  The present invention relates to a wire harness that is provided in a vehicle such as an automobile and includes a plurality of electric wires and includes a plurality of short-circuits that short-circuit the specific electric wires, and a method for manufacturing the wire harness.

  Conventionally, as a wire harness including a short circuit, one using a joint connector for short-circuiting the electric wire is known. For example, Patent Document 1 describes a joint connector that is provided at a terminal of a branched electric wire branched from a trunk line of a wire harness, and the terminals of the branched electric wire are short-circuited by the joint connector. More specifically, a trunk line tape is wound around the electric wire constituting the trunk line, and the branch electric wire is led out to the outside of the trunk line tape. Then, in a state where a common joint connector is connected to the ends of these branch electric wires, a branch line tape different from the main line tape is also wound around these branch electric wires.

JP 2003-297451 A

  In the wire harness described above, since a plurality of branch wires are further branched from the main line around which the main line tape is wound, handling thereof is troublesome. Specifically, it is necessary to wind a tape different from the main line tape around each branch electric wire, and the main line tape is used to fix each branch electric line along the main line. It is necessary to use another tape or the like.

  In addition, since a plurality of branch wires are led out of the trunk of the wire harness, care must be taken in handling the wire harness so that each branch wire and its joint connector do not get caught in other members. Rather, the trouble becomes more pronounced as the number of branch wires increases and as each branch wire becomes longer. In particular, when a large tension acts on the branch wire due to the catch or the like, the connection between the branch wire and the joint connector may be disconnected, which may affect the reliability of the connection.

  In view of such circumstances, the present invention includes a wire harness that is easy to handle and has high connection reliability while including a plurality of short-circuits using joint connectors, and a method for manufacturing the wire harness by a simple process. The purpose is to provide.

  Therefore, in order to solve the above-mentioned problems, the present invention is a wire harness including a plurality of short-circuits, and is wound around a trunk line in which a plurality of electric wires are bundled and the electric wires constituting the trunk line. The main line tape that holds the bundled state, and these branches by being connected to each of the terminals of a plurality of branch electric wires drawn from the main line among the electric wires included in the main line at a plurality of positions along the main line A plurality of joint connectors for short-circuiting the wires to each other, and the plurality of joint connectors are made of a single metal plate and are fitted with a plurality of fittings respectively fitted to the wire-side terminals provided at the ends of the branch wires. A short-circuit metal plate for short-circuiting the branch wires in the fitted state, and the short-circuit metal plate is press-fitted from an opening provided at the rear end. An insulating housing having a plurality of terminal accommodating chambers that are inserted in order to engage the fitting portion with the conductor-side holding portion that holds the circuit board, and the wire-side terminal of each branch wire from the opening. Each joint connector is installed on the trunk line so that the openings of the conductor holding portions of all the joint connectors face one end side of the trunk line, and the trunk line tape is installed on each joint connector. In position, the joint connector is wound around the joint connector and the branch wire and the trunk line from the joint connector to the branch wire connected to the joint connector, and thereby each joint connector is wound around the trunk line. It is fixed on the top.

  Further, in order to solve the above-mentioned problem, the present invention is a wire harness including a plurality of short-circuits, and is wound around a trunk line in which a plurality of electric wires are bundled and an electric wire constituting the trunk line. The main line tape that holds the bundled state, and these branches by being connected to each of the terminals of a plurality of branch electric wires drawn from the main line among the electric wires included in the main line at a plurality of positions along the main line A plurality of joint connectors for short-circuiting the wires to each other, and the plurality of joint connectors are made of a single metal plate and are fitted with a plurality of fittings respectively fitted to the wire-side terminals provided at the ends of the branch wires. The short-circuiting metal plate is short-circuited by press-fitting the short-circuiting metal plate including the joint portion and short-circuiting the branched wires in the fitted state, and the opening provided at the rear end. A conductor holding portion for holding the substrate, and an insulating housing having a plurality of terminal accommodating chambers that are open to the front and into which the wire-side terminals of the branch electric wires are inserted to fit the fitting portions. The joint connectors are located on both sides of a specific intermediate position of the main line, and each joint connector is installed on the main line with the opening of the conductor holding part facing away from the intermediate position. The trunk line tape is bundled around the joint connector, the branch line, and the trunk line from the joint connector toward the branch line connected to the joint connector at the joint connector installation position. The joint connectors are fixed on the main line by being wound around.

  In these wire harnesses, each joint connector and each branch electric wire connected to this joint connector are fixed on the main line, so that the bulge length of the branch electric wire from the main line is reduced. In addition, since the tape for the trunk line is used for fixing the joint connector and the branch wire, the tape winding work for manufacturing the wire harness is simplified, and the joint connector and the branch wire are in direct contact with other members. This is prevented by the trunk tape.

  Further, all the joint connectors have the opening of the conductor holding part directed toward one end of the trunk line, or each joint connector has the opening of the conductor holding part directed to the side opposite to a specific intermediate position of the trunk line. Because it is fixed on the main line, the openings of the joint connectors adjacent to each other on the main line do not face each other, and are pressed into the insulating housing (conductor holding part) from the opening viewed from each opening. Short circuit between metal plates is prevented.

  That is, when adjacent joint connectors are fixed on the main line so that the openings of the conductor holding portions face each other, for example, conductive foreign matters such as water and dirt adhere between the openings of the facing conductor holding portions. This causes a short circuit between the short-circuiting metal plates viewed from the respective openings, and when the distance between the respective openings is narrow, when a current flows through the wire harness and a voltage is applied to the respective short-circuiting metal plates, they are opposed to each other. There may be a case where a short circuit occurs due to discharge between the short-circuiting metal plates as seen through the opening. On the other hand, all joint connectors face the opening of the conductor holding part toward one end of the trunk line, or each joint connector opens the opening of the conductor holding part opposite to a specific intermediate position of the trunk line. Since the openings of the conductor holding portions of the adjacent joint connectors on the main line do not face each other by being fixed on the main line, the adjacent joint connectors can be reliably insulated.

  In addition, since the joint connector is fixed on the main line by the main tape before the branch line at the joint connector installation position on the main line, the branch line for the main line onto the main line thereafter. Fixing with tape is easy to perform, and the tape winding work for manufacturing the wire harness is facilitated.

  That is, by fixing the joint connector on the main line first, both ends of the branch wire connected to the joint connector, in other words, the branch start point from the wire harness and the position of the connection portion with the joint connector Is fixed, it becomes difficult for the branch electric wire to move on the main line, and thereby the winding of the main line tape around the branch electric wire and the main line is facilitated.

  In a wire harness including a plurality of short-circuits according to the present invention, a branch line in which a plurality of electric wires are bundled branches from the main line, the joint connector is provided on the branch line, and the joint connector is connected to the branch line. The branch lines are short-circuited to each other by being connected to each of the terminals of a plurality of branch line wires drawn from the branch line among the wires included in the branch line at one or a plurality of positions along the branch line. The joint connectors are respectively installed on the branch lines so that the openings of the conductor holding portions of all the joint connectors face the terminal opposite to the branch start point of the branch line from the trunk line, and the trunk tape is Wound around the wires that make up the branch line, and at the position where each joint connector is installed, this joint connector Each joint connector is fixed on the branch line by being wound around the joint connector and the branch line branch wire and the branch line all around the branch line connected to the joint connector. Is preferred.

  According to such a configuration, even if a joint connector is provided on the branch line branched from the trunk line, each joint connector in the branch line and each branch line branch wire connected to the joint connector are fixed on the branch line. In this case, the bulge length from the branch line of the branch line branch wire is reduced, and this makes it easier to handle the wire harness than a wire harness in which the bulge length is not reduced in the branch line. Moreover, since the tape for the trunk line is also used for fixing the joint connector and the branch line branch wire in the branch line, the tape winding work for manufacturing the wire harness is simplified, and the joint connector and the branch line branch wire are not included. Direct contact with the members is prevented by the trunk tape.

  Furthermore, since all joint connectors in the branch line are fixed on the branch line with the opening of the conductor holding part facing away from the branch start point of the branch line from the trunk line, not only the trunk line but also the branch line is adjacent. Short-circuiting between the metal plates for short-circuiting of the matching joint connector is prevented.

  Further, in order to solve the above-described problems, the present invention is a wire harness including a plurality of short-circuits, a trunk line in which a plurality of electric wires are bundled, a branch from the trunk line, and a plurality of electric wires are bundled. Included in the branch line at one or a plurality of positions along the branch line, a main line tape wound around the electric wire constituting the main line or the electric wire constituting the branch line, and maintaining the binding state thereof A joint connector for short-circuiting the branch line branch wires to each other by being connected to each of the ends of the branch line branch wires drawn out from the branch line of the wires. It is made of a metal plate, and includes a plurality of fitting portions that are respectively fitted to the electric wire side terminals provided at the ends of the branch line branch wires, and the branch line branch wires are connected to each other in the fitted state. A short-circuiting metal plate to be entangled, and a conductor holding portion for holding the short-circuiting substrate by press-fitting the short-circuiting metal plate from an opening provided at the rear end, and each branch line from the opening to the front Insulating housings each having a plurality of terminal accommodating chambers inserted so that the wire-side terminals of the branch wires are fitted to the fitting portions, and the openings of the conductor holding portions of all the joint connectors are the said branch lines Each joint connector is installed on the branch line so as to face the terminal opposite to the branch start point from the trunk line, and the trunk tape is connected from the joint connector to the joint connector at the installation position of each joint connector. The joint connector, the re-branch wire, and the branch line can be wound around the branch line. Each joint connector, characterized in that it is fixed on the branch by.

  In this way, even when a branch line branches from the main line and a joint connector is provided only on this branch line, each joint connector and each branch line branch wire connected to this joint connector are fixed on the branch line. The bulge length from the branch line of the branch line branching electric wire is reduced, which makes it easier to handle the wire harness than a wire harness in which the bulge length is not reduced in the branch line. Moreover, in addition to bundling the electric wires constituting the main line, the main line tape is also used for bundling the electric wires constituting the branch line and fixing the joint connector and the branch line branching electric wires to the branch line. The tape winding operation is simplified, and the main line tape prevents the joint connector and the branch line branching wire in the branch line from coming into direct contact with other members.

  Furthermore, since all the joint connectors on the branch line are fixed on the branch line with the opening of the conductor holding part facing away from the branch start point of the branch line from the trunk line, the joint connectors adjacent to each other on the branch line are fixed. The openings do not face each other, and short-circuiting between the short-circuiting metal plates press-fitted into the insulating housing from the openings viewed from the openings is prevented.

  Further, at the joint connector installation position on the branch line, the joint contactor is fixed on the branch line by the main tape before the branch line branch wire, so that the branch line branch wire on the branch line thereafter Fixing with the main line tape is facilitated, and the tape winding operation for manufacturing the wire harness is facilitated.

  In the main line of the wire harness, each joint connector is installed on the main line while being folded so that an intermediate portion of the branch electric wire swells in a direction along the main line from the branch start point, and It is preferably fixed on the trunk line. Thus, when each joint connector is fixed on the trunk line, an intermediate portion that bulges in a direction along the trunk line of the branch wire, that is, a slack portion is at a connection portion between the branch wire and the joint connector. Prevent large tensions from acting.

  Further, in the branch line of the wire harness, each joint connector is installed on the branch line while being folded so that an intermediate portion of the branch line branching electric wire swells in a direction along the branch line from the branch start point. It is preferable to be fixed on the branch line by a tape. Thus, when each joint connector is fixed on the branch line, an intermediate part that bulges in a direction along the branch line of the branch line branching wire, that is, a slack part is a connection between the branch line branching wire and the joint connector. Prevent large tension from acting on the part.

  Moreover, in order to eliminate the said subject, this invention is a method for manufacturing the wire harness containing a some short circuit, Comprising: The process of forming a trunk line by bundling a some electric wire, and along the said trunk line A step of drawing out a plurality of specific wires among the wires included in the main line at a plurality of positions as branch wires, and terminals of the plurality of wires drawn out at each position of the main line from which the branch wires are drawn And a plurality of fitting portions each made of a single metal plate and fitted to each of the electric wire side terminals provided at the end of each branch electric wire, and for short-circuiting the branch electric wires in the fitted state A metal plate and a conductor holding portion for holding the short-circuiting substrate by press-fitting the short-circuiting metal plate from an opening provided at the rear end and an opening of the branch wire from the opening and the front A step of short-circuiting the branch wires by connecting a joint connector including an insulating housing having a plurality of terminal receiving chambers inserted so that the terminals are fitted to the fitting portion; A step of installing each joint connector on the trunk line so that the opening of the conductor holding portion faces one terminal side of the trunk line, and the trunk line so as to advance from the one terminal of the trunk line to the other terminal side. The main wire tape is spirally wound around the electric wire constituting the wire to hold the bundling state, and at the joint connector installation position, the joint connector is opened from the end facing the opening of the conductor holding portion. The joint connector, the branch wire and the trunk so as to advance toward the branch wire connected to the joint connector Characterized in that it comprises a step of fixing the respective joint connectors on the main line by winding collectively spirally the trunk tape therearound across and.

  Moreover, in order to eliminate the said subject, this invention is a method for manufacturing the wire harness containing a some short circuit, Comprising: The process of forming a trunk line by bundling a some electric wire, and along the said trunk line A step of drawing out a plurality of specific wires among the wires included in the main line at a plurality of positions as branch wires, and terminals of the plurality of wires drawn out at each position of the main line from which the branch wires are drawn And a plurality of fitting portions each made of a single metal plate and fitted to each of the electric wire side terminals provided at the end of each branch electric wire, and for short-circuiting the branch electric wires in the fitted state A metal plate and a conductor holding portion for holding the short-circuiting substrate by press-fitting the short-circuiting metal plate from an opening provided at the rear end and an opening of the branch wire from the opening and the front A step of short-circuiting the branch wires by connecting a joint connector including an insulating housing having a plurality of terminal receiving chambers inserted so that the terminals are fitted to the fitting portion; and a specific middle of the trunk line Installing each joint connector on the main line so that the joint connector is located on both sides of the position, and the opening of the conductor holding portion of each joint connector faces the opposite side of the intermediate position; and At the installation position of each joint connector, the main wire tape is spirally wound around the electric wire constituting the main line so as to advance from the respective terminals at both ends of the wire to the middle position side. The branch connected to the joint connector from the end facing the opening of the conductor holding portion of the joint connector The joint connectors are fixed onto the main line by spirally winding the main line tape around the joint connector, the branch wire and the main line so as to advance toward the line side. And a process.

  In these methods, the main wire of the wire harness is simply wound around the main wire tape so as to advance from one terminal to the other terminal side or from each terminal at both ends of the main wire to the intermediate position side. The winding of the main line tape and the fixing of each joint connector and each branch wire to the main line are efficiently performed collectively.

  Moreover, each joint connector is installed on the trunk line so that the openings of the conductor holding portions of all the joint connectors face one terminal side of the trunk line, and are advanced from the one terminal of the trunk line to the other terminal side. Thus, since the main line tape is wound in a spiral shape, the joint connector is fixed on the main line before the branch wire at the installation position of each joint connector of the main line. Therefore, the branch wire connected to the joint connector is positioned on the trunk line, which makes it easy to wrap the trunk wire tape around the branch wire and the trunk line at the same time, for the production of the wire harness. Tape winding work can be easily performed.

  On the other hand, when the joint connector is located on both sides of the intermediate position, and each joint connector is installed on the main line so that the opening of the conductor holding portion of each joint connector faces the opposite side of the intermediate position, The main line tape is spirally wound from each end on both ends of the main line so as to advance to the intermediate position side, similarly to the above, at the installation position of each joint connector on the main line, the joint connector before the branch wire Is fixed on the main line, and it becomes easy to wrap the main line tape around the branch wire and the main line.

  That is, as described above, the joint connector is fixed first on the main line, so that both ends of the branch wire connected to the joint connector, in other words, the branch start point from the wire harness and the joint connector By fixing the position of the connection site, the branch wire becomes difficult to move on the trunk line, and this facilitates the wrapping of the trunk line tape around the branch wire and the trunk line.

A step of forming, a step of drawing out a plurality of wires included in the branch line as branch branch wires at a plurality of positions along the branch line, and each of the branch lines from which the branch branch wires are drawn In the position, the step of short-circuiting the branch line branch wires by connecting the joint connectors to the ends of the plurality of drawn-out wires, and the openings of the conductor holding portions of all the joint connectors in the branch lines A step of installing each joint connector on the branch line so as to face the branch start point from the main line. The main line tape is spirally wound around the electric wire constituting the branch line so as to advance from the terminal opposite to the branch start point from the main line of the branch line to the branch start point side, and the bundling state is maintained. In addition, at the joint connector installation position, the joint connector and the branch line branch so that the joint connector proceeds from the terminal on the side facing the opening of the conductor holding portion to the branch line branch electric wire connected to the joint connector. It may further include the step of fixing the joint connectors on the branch line by winding the main line tape in a spiral around the electric wire and the branch line.

  According to this method, even if a branch line branches off from the main line and a joint connector is provided on this branch line, the main line tape is spirally moved so as to advance from the terminal opposite to the branch start point to the branch start point side in the branch line. Winding of the main line tape on the main line of the wire harness, fixing of each joint connector and each branch electric wire to the main line, and winding of the main line tape on the branch line and each of the branch lines The joint connector and each branch line branching wire are efficiently fixed together.

  Moreover, each joint connector is installed on the branch line so that the openings of the conductor holding portions of all joint connectors in the branch line face the terminal opposite to the branch start point, and from the terminal opposite to the branch start point of the branch line. Since the trunk tape is spirally wound so as to advance toward the branch start point, the joint connector is fixed on the branch line before the branch line branch wire at the installation position of each joint connector of the branch line. For this reason, the branch line branch wire connected to the joint connector is positioned on the branch line, which makes it easy to collectively wrap the main line tape around the branch line branch wire and the branch line. Even if the branch line branches off from the main line, the tape winding operation for manufacturing the wire harness can be easily performed.

  Furthermore, when fixing the joint connector on the branch line, each joint connector is installed on the branch line so that the opening of the conductor holding portion faces the terminal opposite to the branch start point of the branch line from the trunk line. A wire harness that is less likely to cause a short circuit between connectors not only on the main line but also adjacent to the branch line can be obtained by an easy operation of winding the main line tape around the connector and the branch line.

  Moreover, in order to eliminate the said subject, this invention is a method for manufacturing the wire harness containing several short circuit, Comprising: The process of forming a trunk line by bundling a some electric wire, and this trunk line are included. A step of forming a branch line branched from the trunk line by drawing a plurality of specific wires out of the wires and bundling the plurality of wires including the drawn wires, and included in the branch lines at a plurality of positions along the branch lines A step of drawing out a plurality of specific wires among the wires as branch branch wires, and a single metal plate at each end of the plurality of wires drawn out at each position of the branch wires from which these branch wire branches are drawn. A plurality of fitting portions that are respectively fitted to the wire-side terminals provided at the ends of the branch-branch wires, and the branch-branch wires are short-circuited in the fitted state. A short-circuiting metal plate, and a conductor holding portion for holding the short-circuiting substrate by press-fitting the short-circuiting metal plate from an opening provided at the rear end, and each branch line electric wire opened from the opening to the front. A step of short-circuiting the branch-branch wires by connecting a joint connector including an insulating housing having a plurality of terminal receiving chambers inserted in order to fit the wire-side terminals of the fitting portion with the fitting portion, Installing each joint connector on the branch line such that the opening of the conductor holding portion of the joint connector faces away from the branch start point of the branch line from the trunk line; and from the one end of the trunk line to the other A step of spirally winding a trunk tape around the electric wire constituting the trunk line so as to advance toward the terminal side and maintaining the bundling state; and the trunk line of the branch line The main line tape is spirally wound around the electric wire constituting the branch line so as to advance from the terminal opposite to the branch start point to the branch start point side, and the binding state thereof is maintained.

A step of fixing the joint connectors on the branch line by winding the main line tape in a spiral manner around the trunk.

  According to this method, even when a branch line branches off from the main line and a joint connector is provided only on this branch line, the main line tape is advanced from the terminal opposite to the branch start point to the branch start point side in the branch line. In addition to bundling the wires constituting the main line of the wire harness with the main tape, the main tape is wound around the branch line, and each joint connector and each branch line branch wire is connected to the branch line. Fixing is performed efficiently in a batch.

  Moreover, each joint connector is installed on the branch line so that the openings of the conductor holding portions of all joint connectors in the branch line face the terminal opposite to the branch start point, and from the terminal opposite to the branch start point of the branch line. Since the trunk tape is spirally wound so as to advance toward the branch start point, the joint connector is fixed on the branch line before the branch line branch wire at the installation position of each joint connector of the branch line. For this reason, the branch line branch wire connected to the joint connector is positioned on the branch line, which makes it easy to collectively wrap the main line tape around the branch line branch wire and the branch line. Even if the branch line branches off from the main line, the tape winding operation for manufacturing the wire harness can be easily performed.

  Furthermore, when fixing the joint connector on the branch line, each joint connector is installed on the branch line so that the opening of the conductor holding portion faces the terminal opposite to the branch start point of the branch line from the trunk line. A wire harness that is less likely to cause a short circuit between connectors that are fixed adjacent to each other on the branch line can be obtained by an easy operation such as winding the tape for the trunk line around the connector and the branch line.

  In the step of installing each joint connector on the main line, each joint connector is installed on the main line while folding the intermediate portion of the branch wire so as to bulge from the branch start point in the direction along the main line. It is preferable to do this.

  By installing the joint connector and fixing it on the main line in this way, the slack portion of the branch wire prevents a large tension from acting on the connection portion between the branch wire and the joint connector, and the connection reliability is higher. A wire harness is obtained.

  Moreover, in the manufacturing method, for each joint connector, the main line tape is spirally wound so as to advance from the terminal on the side facing the opening of the conductor holding portion to the branch wire side connected to the joint connector. Since the wire is fixed on the main line, the tape winding operation for manufacturing the wire harness can be easily performed even if the middle part of the branch wire is expanded in the direction along the main line.

  That is, the joint connector is fixed on the main line before the branch electric wire by the main line tape, so that the intermediate portion where the branch electric wire bulges is also positioned on the main line. Therefore, it is possible to easily wrap the main wire tape around the branch wire and the main wire that are folded so that the intermediate portion bulges. As a result, the tape winding work for manufacturing the wire harness can be easily performed. Can be done.

  Further, in the step of installing each joint connector on the branch line, each joint connector is placed on the branch line while folding an intermediate portion of the branch line branching wire so as to bulge from the branch start point in a direction along the branch line.

High wire harness can be obtained.

  In addition, in the manufacturing method, for each joint connector, the main line tape is spirally wound so as to advance from the terminal on the side where the opening of the conductor holding portion faces to the branch branch electric wire connected to the joint connector. In order to fix the connector on the branch line, as in the case of fixing the joint connector on the trunk line, even if the middle part of the branch line branching wire bulges in the direction along the branch line, the tape for manufacturing the wire harness Winding work can be easily performed.

  From the above, according to the present invention, while constructing a plurality of short-circuits with branch wires and joint connectors, easy handling and connection reliability can be achieved by wrapping the main line tape around each joint connector and the main line. A wire harness having a high height can be provided, and a method by which the wire harness can be manufactured by a simple process can be provided.

I) Manufacture process of main line I-1) Wiring of electric wire 10 A plurality of electric wires 10 are bundled to form a main line 12, and at a plurality of positions along the main line 12 (drawing position 50), A plurality (four in this embodiment) of electric wires 10 out of the electric wires 10 are drawn out from the main line 12 as branch wires 14. Each drawing position 50 does not need to be provided at substantially equal intervals along the trunk line 12 as shown in FIGS. 11A and 11B, and the first harness circuit 17 is required in the wire harness 100. It may be provided in. For each electric wire 10, a so-called covered electric wire is used, and the electric wire 10 has a conductor and an insulating coating that covers the conductor.

  In this embodiment, in order to connect each branch wire 14 to the common joint connector JC at each lead-out position 50, a wire-side terminal 20 as shown in FIG. 6 and FIG. It is installed. The electric wire side terminal 20 has a female electrical contact portion 22 and an electric wire crimping portion 24 at the front and rear. The electrical contact portion 22 has a hollow rectangular tube-shaped main body and a contact spring piece 26 provided so as to be able to bend in the main body. From the bottom wall of the electrical contact portion 22, a locked piece 28 for locking to the joint connector JC protrudes outward.

  The terminal of each branch electric wire 14 is previously subjected to a treatment for removing the insulating coating and exposing the conductor, and the electric wire crimping portion 24 embraces the terminal of the conductor and the insulating coating in the vicinity thereof. By being bent, it is crimped to the end of the branch wire 14 and is electrically connected to the conductor.

I-2) Connection to joint connector JC By connecting the wire-side terminal 20 attached to each branch wire 14 at each extraction position 50 to the joint connector JC as shown in FIGS. The electric wire side terminals 20 are short-circuited.

  The joint connector JC according to this embodiment includes a single short-circuit conductor 30 and an insulating housing 40 for holding the short-circuit conductor 30. The short-circuiting conductor 30 is made of a conductive material, and is short-circuited between the electric wire side terminals 20 by being commonly connected to the electric wire side terminals 20. The insulating housing 40 is integrally formed of an insulating material such as a synthetic resin, and can be held in a state where the shorting conductor 30 is stored. Specifically, the insulating housing 40 is flat in the thickness direction of the shorting conductor 30. Have a different shape.

  The short-circuiting conductor 30 according to this embodiment is composed of a short-circuiting metal plate formed by punching a single metal plate into an appropriate shape, and integrally includes a plurality of electrical contact portions 32 and a short-circuit portion 34. . Each electric contact portion 32 is a male (tab) fitting portion that can be fitted into the female electric contact portion 22 of each electric wire side terminal 20, and these electric contact portions 32 are parallel to the width direction thereof. Is arranged. The short-circuit portion 34 extends in the arrangement direction of the electrical contact portions 32, and the proximal end of each electrical contact portion 32 is connected to the short-circuit portion 34.

  The insulating housing 40 includes a pair of side walls 44 that connect the flat top wall 41 and the bottom wall 42 that are parallel to each other, and both end portions in the width direction of the walls 41 and 42 (that is, the left end portions and the right end portions). And integrally. These walls 41, 42, 44 constitute the outer wall of the insulating housing 40.

  The rear end portion of the outer wall (the right end portion in FIGS. 6 to 9) constitutes a conductor holding portion 43. The short-circuiting portion 34 of the short-circuiting conductor 30 is press-fitted into the conductor holding portion 43 from the opening 43 a provided at the rear end of the insulating housing 40, whereby the short-circuiting portion 34 is held by the conductor holding portion 43. .

  The conductor holding portion 43 has a shape that holds the short-circuit portion 34 of the short-circuiting conductor 30. Specifically, the short circuit 34 has an outer shape that is slightly larger than the short circuit part 34 and extends in the arrangement direction of the electrical contact parts 32 of the short circuit conductor 30, and the short circuit part 34 can be inserted from the rear (right side in FIG. 6). The conductor insertion opening 43a is enclosed. The short-circuit portion 34 is press-fitted into the conductor holding portion 43 from the insertion port 43a in a posture in which each electrical contact portion 32 faces forward. More specifically, protrusions 34 a as shown in FIG. 8 are formed at both ends in the width direction of the short-circuit portion 34, and these protrusions 34 a bit into the inner surface of the conductor holding portion 43 to short-circuit the conductor holding portion 43. The part 34 is fixed.

  A plurality (three in the figure) of partition walls 45 parallel to the side walls 44 are arranged in the connector width direction at a portion in front of the conductor holding portion 43. Each partition wall 45 defines a terminal accommodating chamber 47 between another partition wall 45 or the side wall 44 adjacent to the partition wall 45. Each terminal accommodating chamber 47 has a shape that opens forward and allows the electric wire side terminal 20 to be inserted through the opening. Each electrical contact portion 32 of the short-circuiting conductor 30 protrudes from the rear in each terminal accommodating chamber 47, and the electrical contact portion 22 of the electric wire side terminal 20 inserted into the terminal accommodating chamber 47 is connected to the electrical contact portion 32. The electric wire side terminal 20 and the short-circuiting conductor 30 are electrically connected by fitting.

  Lances (terminal locking portions) 46 are formed on the bottom wall 42 at positions corresponding to the respective terminal accommodating chambers 47. Each lance 46 is surrounded by a substantially U-shaped slit 42 a (see FIG. 9) formed in the bottom wall 42, and can be bent and deformed in the thickness direction with respect to the main body of the bottom wall 42. A free end portion is provided, and a claw-like locking portion is formed at the free end portion. As shown in FIG. 6, this locking portion is bent and deformed to come into contact with the inserted electric wire side terminal 20 to allow passage of the electric wire side terminal 20 and elastically return to a normal position after the passage. By doing so, the locked piece 28 of the electric wire side terminal 20 is restrained from the rear (see FIG. 7). That is, the electric wire side terminal 20 is locked at a position where the electric wire side terminal 20 is fitted to the electric contact portion 32.

  Accordingly, in the joint connector JC, the terminal 20 of each branch wire 14 is inserted into the terminal accommodating chamber 47 and fitted into the electrical contact portion 32 of the short-circuiting conductor 30, so A short circuit between the electric wire side terminals 20 using the conductor 30 as a medium is achieved. That is, at each extraction position 50, the first short circuit 17 is formed by each joint connector JC and each branch electric wire 14 connected to the joint connector JC.

I-3) Installation of Joint Connector JC The joint connector JC to which each branch wire 14 is connected at each lead-out position 50 as described above is installed on the trunk line 12 so that the branch wire 14 is folded. Specifically, in this embodiment, the joint connector JC is folded so that the intermediate portion 16 of each branch wire 14 swells in the direction along the trunk line 12, and the joint connector JC has a branch start point 15 (see FIG. 2). It is installed in the vicinity of

  Each joint connector JC is installed on the trunk line 12 with the short-circuit conductor insertion port 43a of the conductor holding portion 43 facing away from the specific intermediate position 52 of the trunk line 12 (FIGS. 11A and 11). (See (b)). Specifically, the intermediate position 52 is set at a position on the trunk line 12 such that the drawing position 50 is located on both sides of the intermediate position 52, so that the joint connector is located on both sides of the intermediate position 52. JC is located. Each joint connector JC in this state is folded so that the intermediate portion 16 of the branch wire 14 swells in the direction along the trunk line 12, and the short-circuit conductor insertion port 43 a of the conductor holding portion 43 is opposite to the intermediate position 52. It is installed on the trunk line 12 so as to face the side.

  This installation may be performed just before the next tape winding operation, for example, and the operator may simply press the joint connector JC with a finger or the like, or the joint connector JC may be temporarily fixed with an adhesive tape or the like. It may be broken.

  Each joint connector JC installed on the main line 12 is installed in such a posture that the bottom wall 42 of the insulating housing 40 on which the lance 46 is formed faces the main line 12 side as shown in FIG. Alternatively, it may be installed in such a posture as to face the side opposite to the main line 12. Further, as in this embodiment, the joint connectors JC may be installed along the main line 12 in a plurality of lines instead of being arranged in a straight line on the main line 12, and installed along a curve or the like. May be.

I-4) Tape winding operation The trunk line tape 18 is spirally wound around the electric wires 10 constituting the trunk line 12 so as to maintain the bundled state. This winding may be performed so as to cover the entire surface of the main line 12 as shown in FIGS. 11A and 11B, or at a gap where a part of the main line 12 is exposed. May be. In FIG. 11A and FIG. 11B, the branch line 60 is omitted for convenience of explanation.

  Specifically, the main line tape 18 is spirally wound around the electric wires 10 constituting the main line 12 so as to advance from the respective terminals at both ends of the main line 12 to the intermediate position 52 side (see FIG. 11B). See arrow.) When the winding of the main line tape 18 reaches the installation position of each joint connector JC, the side where the short-circuit conductor insertion port 43a of the conductor holding portion 43 faces the joint connector JC (FIGS. 11A and 11B). ) In the periphery of the joint connector JC, the branch wire 14 and the trunk line 12 so as to advance from the terminal on the side opposite to the intermediate position 52) to the branch wire 14 side connected to the joint connector JC. The tape 18 is wound spirally at once. Thus, using the trunk line tape 18, it is possible to efficiently hold the bundled state on the trunk line 12 and fix the joint connector JC on the trunk line 12.

II) Manufacturing process of branch line II-1) Routing of electric wire 10 At a specific intermediate position 52 (branch lead-out position 55) of the trunk line 12 in which a plurality of electric wires 10 are bundled, a plurality of electric wires 10 among the electric wires 10 Is drawn from the main line 12. Thus, the branch line 60 is formed by bundling the electric wires 10 drawn from the trunk line 12 or bundling a plurality of electric wires 10 a so as to include the drawn electric wires 10. In addition to the electric wire 10 drawn out from the main line 12, for example, a plurality of electric wires 10 a constituting the branch line 60 include a main line from a connector provided at a terminal of the branch line 60 (terminal opposite to the branch start point from the main line 12). An electric wire that extends to the side 12 and is drawn out from the middle of the branch line 60 without reaching the main line 12 and forms a part of the second short circuit 17a (that is, an electric wire routed only in the branch line 60) is also included. May be.

  At a plurality of positions along the branch line 60 (drawing position 57: see FIG. 1), a plurality (four in this embodiment) of the electric wires 10a constituting the branch line 60 are branch lines 60a as branch lines 60a. (See FIG. 4). Each drawing position 57 should just be provided in the site | part which requires the 2nd short circuit 17a similarly to the drawing position 50 in the trunk line 12. FIG.

A plurality of wires 10a drawn out from the branch line 60 as a branch branch lines 14a is not limited to the electric wire 10a ₁ which is routed from the mains 12 to branch lines 60 as shown in FIG. 12. For example, Figure 13 only in the branch line 60 as shown in wired been may be one containing only the wire 10a _2, wired electric wires 10a ₁ and the branch 60 from the mains 12, as shown in FIG. 14 to the branch line 60 It may include both of the electric wires 10a ₂ wired only by the wires. The electric wire 10 a ₂ wired only in the branch line 60 extends from the connector C disposed at the end of the branch line 60 and reaches the branch line without reaching the main line 12 as shown in FIGS. 13 and 14. from the middle 60 of or other connector C is wire 10a ₂ as being connected to the joint connector JC constituting the second short circuit 17a. Moreover, the connector C of the terminal of the branch line 60 includes a plurality of connectors C provided in the branch line 60 and a portion 60a where the branch line 60 is further branched. Further, in this embodiment, one branch line 60 is branched from the main line 12, but the present invention is not limited to this, and two or more branch lines 60 may be branched from the main line 12. Moreover, in this embodiment, in order to connect each branch line electric wire 14a to the common joint connector JC in each extraction position 57 in the branch line 60, the electric wire side terminal 20 is previously attached to the terminal of each branch line branch electric wire 14a. (See FIGS. 6 and 7).

II-2) Connection to Joint Connector JC The wire-side terminal 20 attached to each branch line branch wire 14a at each lead-out position 57 in the branch line 60 is connected to the joint connector JC, and the joint connector JC and each branch line branch wire 14a. Thus, the second short circuit 17a is configured at the extraction position 57. At this time, in the joint connector JC, the wire-side terminal 20 at the end of each branch-branch wire 14a is inserted into the terminal accommodating chamber 47 and fitted into the electrical contact portion 32 of the short-circuiting conductor 30. The electric wire side terminals 20 are short-circuited using the short-circuiting conductor 30 as a medium (see FIGS. 6 and 7).

II-3) Installation of Joint Connector JC The joint connector JC to which the branch line wires 14a are connected at the lead-out positions 57 of the branch line 60 as described above is formed by folding the branch line branch wires 14a as shown in FIG. 60.

  At this time, all the joint connectors JC are on the branch line 60 with the short-circuit conductor insertion port 43a of the conductor holding portion 43 facing the terminal on the opposite side to the branch start point of the branch line 60 from the trunk line 12 (in the upper right direction in FIG. 1). Installed.

II-4) Tape winding work The trunk tape 18 is spirally wound around the electric wire 10a constituting the branch line 60 so as to maintain the bundled state.

  Specifically, the main line tape 18 is wound around the electric wire 10a constituting the branch line 60 so as to advance from the terminal opposite to the branch start point of the branch line 60 to the branch start point side (see the arrow along the branch line 60 in FIG. 1). Is spirally wound. When the winding of the main line tape 18 reaches the arrangement position of each joint connector JC, the short-circuit conductor insertion port 43a of the conductor holding portion 43 of the joint connector JC faces the joint connector JC as in the manufacturing process of the main line 12. The main line tape 18 is spirally wound around the joint connector JC, the branch line branch wire 14a and the branch line 60 so as to advance from the terminal to the branch line branch wire 14a connected to the joint connector JC. Wrap it in a shape.

  Since each joint connector JC and each branch electric wire 14 connected to this joint connector JC are fixed on the main line 12 as described above, the bulging length of the branch electric wire 14 from the main line 12 is reduced. Similarly, also in the branch line 60, each joint connector JC and each branch line branch wire 14a connected to this joint connector JC are fixed on the branch line 60. Therefore, the bulge length of the branch line branch wire 14a from the branch line 60 is small. Reduced. Moreover, each joint connector JC and each branch wire 14 fixed to the main line 12 and each joint connector JC and each branch line 14a fixed to the branch line 60 are covered from the outside by the main line tape 18. Since direct contact between these and other members is prevented, handling of the wire harness 100 is facilitated.

  Further, in the trunk line 12, each joint connector JC is fixed on the trunk line 12 with the short-circuit conductor insertion port 43 a of the conductor holding portion 43 facing away from a specific intermediate position 52 (branch line lead-out position 55) of the trunk line 12. Therefore, the short-circuit conductor insertion ports 43a of the joint connectors JC adjacent to each other on the trunk line 12 do not face each other, and the insulating housing 40 (conductor holding portion 43) is inserted into the short-circuit conductor insertion ports 43a. ) The short-circuiting conductors 30 that are press-fitted inside are prevented from short-circuiting.

  For example, when the adjacent joint connector JC is fixed on the trunk line 12 so that the short-circuiting conductor insertion ports 43a of the conductor holding portion 43 are opposed to each other, water is interposed between the short-circuiting conductor insertion ports 43a of the opposing conductor holding portion 43. As a result of adhesion of conductive foreign matter such as dirt or dirt, short-circuiting conductors 30 viewed from the insertion openings 43a are short-circuited, and if the distance between the insertion openings 43a is narrow, a current flows through the wire harness 100 for each short-circuiting. When a voltage is applied to the conductor 30, a short circuit due to discharge may occur between the short-circuiting conductors 30 viewed through the opposing short-circuiting conductor insertion openings 43 a. On the other hand, in the wire harness 100 according to this embodiment, each joint connector JC is fixed on the trunk line 12 with the short-circuit conductor insertion port 43a of the conductor holding portion 43 facing away from the intermediate position 52. In addition, since the short-circuit conductor insertion ports 43a of the conductor holding portions 43 of the adjacent joint connectors JC on the main line 12 are not opposed to each other, insulation between the adjacent joint connectors JC can be reliably achieved.

  In the branch line 60, all the joint connectors JC are installed on the branch line 60 with the short-circuit conductor insertion port 43 a of the conductor holding portion 43 facing the terminal opposite to the branch start point of the branch line 60. However, the short-circuit conductor insertion openings 43a of the adjacent joint connectors JC do not face each other, and the short-circuit conductors 30 viewed from the respective short-circuit conductor insertion openings 43a are prevented from being short-circuited. In addition, all the joint connectors JC in the branch line 60 are placed on the branch line 60 with the short-circuit conductor insertion port 43a facing the terminal opposite to the branch start point, thereby approaching between the main line 12 and the branch line 60. The short-circuit conductor insertion openings 43a of the joint connector JC are also prevented from facing each other, and the short-circuit conductor 30 as seen through the respective short-circuit conductor insertion openings 43a between the joint connector JC of the adjacent branch line 60 and the joint connector JC of the trunk line 12 is prevented. Short circuit between each other is also prevented.

  Further, as in this embodiment, the main line tape 18 is wound around the joint connector JC and the main line 12 (or the branch line 60) so as to cover the entire surface of the conductor holding portion 43 even at the installation position of the joint connector JC. Since the short-circuit conductor insertion port 43a is also closed by the main line tape 18, the insulation between the adjacent joint connectors JC can be further ensured.

  At the installation position of each joint connector JC on the main line 12, the joint connector JC is fixed on the main line 12 by the main line tape 18 before the branch line 14. The main wire tape 18 is easily fixed, and the tape winding work for manufacturing the wire harness 100 can be facilitated.

  That is, when the joint connector JC is first fixed onto the main line 12, both ends of the branch wire 14 connected to the joint connector JC, that is, the branch start point 15 (see FIG. 2) from the wire harness 100 and the joint The position of the connection part with the connector JC is fixed, and thus the branch wire 14 is difficult to move on the trunk line 12. Therefore, even if the joint connector JC is installed on the trunk line 12 so that the intermediate portion 16 (see FIG. 3) of the branch wire 14 bulges in the direction along the trunk line 12 as in this embodiment, the joint connector Since the JC is fixed on the trunk line 12 before the branch wire 14, the intermediate portion 16 where the branch wire 14 bulges is also positioned on the trunk line 12, and the intermediate portion where the branch wire 14 bulges. The main line tape 18 can be easily wound around the main line 16 and the main line 12.

  Also, at the installation position of each joint connector JC in the branch line 60, the joint connector JC is fixed on the branch line 60 by the main line tape 18 before the branch line branching wire 14a, similarly to the main line 12, and thereafter The branch line 14a can be easily fixed on the branch line 60 with the trunk tape 18, and the tape winding operation for manufacturing the wire harness 100 can be facilitated.

  Further, in the trunk line 12, the joint connector JC is installed on the trunk line 12 with the intermediate portion 16 of the branch wire 14 folded as described above, so that the slack portion (intermediate portion of the folded branch wire 14 is intermediate). The length of the portion 16) is shorter than the length of the original branch wire 14 (about half in this embodiment), and therefore the work of winding the trunk tape 18 around the slack portion is facilitated. Similarly, in the branch line 60, the joint connector JC is installed on the branch line 60 in a state where the middle part of the branch line branch wire 14a is folded, so that the length of the slack portion of the folded branch line branch wire 14a is originally Therefore, the operation of winding the main tape 18 around the slack portion is facilitated.

  In this way, in the trunk line 12, the branch wire 14 is folded, so that the branch wire 14 is compactly accommodated on the trunk line 12, and the slack given to the branch wire 14 by the folding is the branch. A large tension is prevented from acting on the connection portion between the electric wire 14 and the joint connector JC. Similarly, in the branch line 60, the branch line branch wire 14a is folded, so that the branch line branch wire 14a is compactly accommodated on the branch line 60, and the slack given to the branch line branch wire 14a by the fold is A large tension is prevented from acting on the connecting portion between the branch line 14a and the joint connector JC.

  Next, a second embodiment of the present invention will be described with reference to FIGS. 15 (a) and 15 (b). The same reference numerals are used for the same configurations as in the first embodiment, and a detailed description will be given. Omitted, only the different configuration will be described in detail. Further, in this embodiment as well as the first embodiment, the wire harness 100 is manufactured by two processes of a trunk line manufacturing process and a branch line manufacturing process. The branch line manufacturing process according to this embodiment is the first embodiment. Since it is the same process as the manufacturing process of the branch line which concerns on a form, description is abbreviate | omitted.

I) Manufacture process of trunk line I-1) Routing of electric wire 10 A plurality of electric wires 10 are bundled to form a main wire 12, and at a plurality of extraction positions 50 along the main wire, The plurality of electric wires are drawn out from the main line 12 as the branched electric wires 14.

I-2) Connection to Joint Connector JC The wire-side terminal 20 attached to each branch wire 14 at each lead-out position 50 is connected to the joint connector JC, and the lead-out position between the joint connector JC and each branch wire 14 50, a first short circuit 17 is constructed (see FIG. 2). At this time, in the joint connector JC, the wire-side terminal 20 at the end of each branch wire 14 is inserted into the terminal accommodating chamber 47 and fitted into the electrical contact portion 32 of the short-circuiting conductor 30, thereby causing the short-circuit. The electric wire side terminals 20 are short-circuited using the working conductor 30 as a medium (see FIGS. 6 and 7).

I-3) Installation of Joint Connector JC The joint connector JC to which each branch wire 14 is connected at each extraction position 50 as described above is installed on the trunk line 12 so as to fold the branch wire 14 (see FIG. 3). .

  At this time, as shown also in FIG. 15A and FIG. 15B, all the joint connectors JC connect the short-circuit conductor insertion port 43a of the conductor holding portion 43 to one terminal side of the trunk line 12 (FIG. 15B). ) On the main line 12 toward the right side). In FIGS. 15A and 15B, the branch line 60 is omitted for convenience of explanation as in the first embodiment.

I-4) Tape winding operation The trunk line tape 18 is spirally wound around the electric wires 10 constituting the trunk line 12 so as to maintain the bundled state.

  Specifically, the trunk line tape 18 is spirally wound around the electric wire 10 constituting the trunk line 12 so as to advance from one terminal of the trunk line 12 to the other terminal side (see the arrow in FIG. 15B). wear. When the winding of the main line tape 18 reaches the arrangement position of each joint connector JC, as in the first embodiment, the side where the short-circuit conductor insertion port 43a of the conductor holding portion 43 faces the joint connector JC (see FIG. The joint connector JC, the branch wire 14 and the trunk line 12 are advanced from the terminal on the right side of 15 (b) to the branch wire 14 side connected to the joint connector JC (left side in FIG. 15B). The main line tape 18 is spirally wound around the periphery.

  Even if all the joint connectors JC are installed on the trunk line 12 with the short-circuit conductor insertion port 43a of the conductor holding portion 43 facing one terminal side of the trunk line 12 as in this embodiment, as in the first embodiment. The short-circuiting conductor insertion ports 43a of the joint connectors JC adjacent on the trunk line 12 do not face each other, and the short-circuiting conductors 30 viewed from the respective short-circuiting conductor insertion ports 43a can be prevented from being short-circuited.

  Moreover, since the joint connector JC is fixed on the main line 12 by the main line tape 18 before the branch wire 14 at the installation position of each joint connector JC on the main line 12 as well, The branch wire 14 can be easily fixed to the trunk line 12 with the trunk tape 18, and the tape winding work for manufacturing the wire harness 100 can be facilitated.

  In addition, the wire harness 100 of this invention is not limited to the said 1st Embodiment and 2nd Embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.

  For example, as in the first embodiment and the second embodiment, all the joint connectors JC have the trunk line 12 in a state in which the intermediate portion 16 of the branch wire 14 (or the branch branch wire 14a) connected to the joint connector JC is folded. It is not necessary to install on (or branch line 60). That is, in the plurality of joint connectors JC installed on the trunk line 12 (or the branch line 60), it is sufficient that the short-circuit conductor insertion ports 43a of the conductor holding portions 43 of the adjacent joint connectors JC do not face each other. The joint connector JC may be installed on the trunk line 12 (or the branch line 60) so that the branch wire 14 (or the branch line branch line 14a) extends along the trunk line 12 (or the branch line 60).

  Further, unlike the first embodiment and the second embodiment, it is not necessary to provide the first short circuit 17 on the main line 12 in the wire harness 100, and the second short circuit 17a is provided only on the branch line 60. Also good. Moreover, the wire harness 100 does not need to be provided with the branch line 60, and may be configured by only the trunk line 12.
