Description

  The present invention includes a plurality of terminals that are respectively attached to terminals of a plurality of electric wires each having a conductor, and the metal constituting the conductor of the electric wire is different from the metal constituting the terminal Further, the present invention relates to a connector with an anticorrosion function that can effectively inhibit corrosion caused by contact between different kinds of metals.

  Conventionally, a terminal made of a metal (generally copper or copper alloy) similar to the metal constituting the conductor is generally attached to the end of the electric wire having a conductor. Corrosion caused by the difference between the metal that constitutes the conductor of the wire and the metal that constitutes the terminal, that is, corrosion caused by contact of dissimilar metals with the use of a so-called aluminum electric wire having a conductor made of a system material. It is a problem. For example, when a copper terminal is crimped to an aluminum conductor included in an electric wire, the standard electrode potential of copper is +0.34 V, and the standard electrode potential of aluminum is −1.66 V. A standard electrode potential difference as large as 2.00 V exists between the terminals. Therefore, if moisture adheres to the contact portion between the two, for example, due to running in rainy weather, car washing, or dew condensation, ionization of the aluminum conductor which is electrically base proceeds and the corrosion proceeds.

  Conventionally, as a means for preventing such corrosion, a contact portion between dissimilar metals is applied to the contact portion by applying water-resistant coating, heat-shrinkable tube deposition, or resin insert molding. A technique for preventing the adhesion of moisture is known.

  Since each of the conventional techniques is a process performed on each terminal, the time and cost required for the process significantly increase as the number of terminals increases. As a means for avoiding such inconvenience, it is conceivable to collectively waterproof by housing a plurality of terminals in a waterproof connector housing, but such a waterproof connector housing is fitted between terminals. Since it is designed to completely eliminate the intrusion of moisture into the housing in order to waterproof the entire terminal including the part, it is expensive and large.

  In view of the above circumstances, the present invention can efficiently and efficiently suppress corrosion of contact portions between a plurality of electric wires and terminals connected thereto without using an expensive and large waterproof housing. An object of the present invention is to provide an anticorrosive connector.

  In order to achieve this object, the connector with anticorrosion function according to the present invention is a plurality of terminals that are respectively attached to terminals of a plurality of electric wires each having a conductor, and are made of a metal different from the metal constituting the conductor. And a housing that collectively accommodates these terminals, and an anticorrosive body for preventing corrosion at a contact portion between the terminal and the conductor of the electric wire. Each of the terminals is located on the rear side of the electrical contact portion that is fitted and electrically connected to the counterpart terminal, and is crimped to the end of the electrical wire to be a conductor of the electrical wire. And a wire crimping portion that is in contact with each other so as to be electrically connected. The housing has a plurality of terminal insertion holes into which the electrical contact portions of the terminals are inserted along the axial direction of the terminals, and is located behind the terminal insertion holes and straddles the terminal insertion holes. The anticorrosive body accommodation space which has a shape and can accommodate the anticorrosive body is defined. The anticorrosive body has a shape retaining property that is accommodated in the anticorrosive body accommodating space without leaking, and the electrical contact portion of each terminal penetrates the anticorrosive body and is inserted into a terminal insertion hole corresponding to the terminal. And a gel-like body having a viscosity that wraps around the contact portion between the wire crimping portion of the terminal and the conductor of the wire in a state where the insertion is completed and prevents moisture from entering the contact portion.

  In this connector with anticorrosion function, the common anticorrosion body efficiently and collectively prevents corrosion at the contact portion between the wire crimping portion of the terminal included in the connector with anticorrosion function and the conductor of the wire to which the wire crimping portion is crimped. Deterred. That is, the same work as the terminal insertion work in a normal connector, in which the electrical contact portion is inserted into the corresponding terminal insertion hole while the electrical contact portion of each terminal is pushed into the corrosion prevention body to break through the corrosion prevention body. It is possible to form an anticorrosion state in which the anticorrosive body wraps the contact portion between the wire crimping portion of each terminal and the conductor of the electric wire simply by performing the above. Further, the anticorrosion body only needs to permit the penetration of each terminal and wrap around the contact portion between the wire crimping portion and the conductor of the wire in the penetration state, and into the housing like a conventional waterproof connector. Since it is not necessary to completely eliminate the intrusion of moisture, corrosion prevention of each contact portion can be achieved without significantly increasing the size of the housing and significantly increasing the cost.

Furthermore, in the first anti-corrosion function with the connector according to the present invention, the terminal, between the said electrical contact portion wire crimping portion, larger cross-section than the contact portion between the conductor of the with the wire crimping portion wire the have that have a cross-sectional expanded portion which is in close contact with the anti-corrosion member. This cross-sectional enlarged portion ensures the protection of the contact site in the anticorrosion body by being in close contact with the anticorrosion body.

The second anti-corrosion function with the connector according to the present invention, further, Ru comprising a retainer attached to the housing for locking the terminal in a state in which the electrical contact portion is inserted into the terminal insertion hole. The retainer includes an insertion allowable position that allows insertion of the electrical contact portion into each terminal insertion hole, and the electrical contact portion from the terminal insertion hole in a state where the electrical contact portion is inserted into the terminal insertion hole. It is attached to the housing so as to be movable between a locking position for locking the terminal so as to prevent detachment of the terminal. And in this case, it is possible to improve the anticorrosion function of each said contact site by the said anticorrosive body using the said retainer. Specifically, the retainer mounting position is determined so that the retainer compresses the anticorrosive body in cooperation with the housing as the retainer moves from the insertion allowable position to the locking position. That's fine. The compression of the anticorrosive body by the retainer increases the degree of adhesion between each terminal or each electric wire and the anticorrosive body, thereby enhancing the function of the anticorrosive body to prevent moisture from entering the wire crimping portion.

  Moreover, when the shape-retaining property of the gel-like body constituting the anticorrosive body is relatively high, the anticorrosive body has a slit penetrating along the axial direction of the terminal, and the terminal along the slit The electrical contact portion may be inserted. The slit suppresses the terminal from being shaken in the width direction of the slit when the terminal is inserted into the slit, thereby exhibiting a function of guiding the terminal to the corresponding terminal insertion hole and Make the insertion work easier.

  As described above, according to the present invention, it is possible to efficiently suppress the corrosion of contact portions between a plurality of electric wires and terminals connected thereto without using an expensive and large waterproof housing. A possible anticorrosive connector is provided.

  Preferred embodiments of the present invention will be described with reference to the drawings. In this embodiment, a female connector that can be coupled to a male connector (not shown) is disclosed as the connector with anticorrosion function according to the present invention, but the present invention is not limited to this. For example, the present invention can also be applied to a male connector, a joint connector for short-circuiting a plurality of electric wires, and a ground connector for connecting a plurality of grounding wires to a grounded part.

  The connector shown in FIGS. 1 to 10 includes a plurality of female terminals 10, a housing 20 that collectively accommodates these terminals 10, an anticorrosion body 30, and a retainer 40.

  As shown in FIG. 6, each terminal 10 is attached to each end of a plurality of electric wires 50 having a conductor 52 and an insulating coating 54 covering the conductor 52, and is made of a metal different from the metal constituting the conductor 52. Composed. In this embodiment, a so-called aluminum electric wire whose conductor is made of aluminum is used as the electric wire 50, whereas each terminal 10 is made of a plate material made of copper or a copper alloy.

  Each of the terminals 10 includes an electrical contact portion 12 that comes into electrical connection with the male terminal when a male terminal (not shown) is inserted, and an electric wire located behind the electrical contact portion 12. The electric wire crimping portion 14 includes a pair of conductor barrels 15 and an insulation barrel 16 located behind the pair of conductor barrels 15. On the other hand, each of the electric wires 50 is subjected to a process of removing the insulating coating 54 at the end portion thereof and exposing the conductor 52. The conductor barrel 15 is crimped to the conductor 52 so as to embrace the exposed conductor 52, and the insulation barrel 16 is crimped to the insulating sheath 54 so as to embrace the insulating coating 54 behind the exposed conductor 52. .

  Furthermore, in the terminal 10 according to this embodiment, a cross-sectional enlarged portion 13 is formed between the electrical contact portion 12 and the wire crimping portion 14. The cross-sectional enlarged portion 13 is formed by adding a resin molding so as to enlarge the cross-section of the terminal 10 in order to ensure close contact with the anticorrosive body 30 described later. It has a cross section that is slightly larger than the cross section at the contact portion with the conductor 52 (here, a cross section close to a rectangle as shown in FIG. 4).

  Specifically, as shown in FIG. 13A, the enlarged cross-sectional portion 13 according to this embodiment is between the electrical contact portion 12 and the wire crimping portion 14 in the metal plate constituting the terminal 10. It is comprised by the intermediate part 13a located in this, and the resin molding 13b with which this is filled. The intermediate portion 13a has a bottomed cross section that is open in a specific direction (upward in the drawing), and the resin molded product 13b is fixed by being press-fitted into the intermediate portion 13a, for example.

  The shape of the cross-sectional enlarged portion 13 can be freely set by changing the shape of the resin molded product 13b. For example, as shown in FIG. 13 (b), the resin molded product 13b receives from an anticorrosive body 30 described later by making the cross-sectional shape of the upper half of the resin molded product 13b an outwardly convex curve, for example, a semicircle. The surface pressure can be equalized. Furthermore, as shown in FIG. 13 (c), if the both ends in the width direction of the resin molded product 13b have a shape that covers both end edges of the intermediate portion 13a of the metal plate from above, the outer shape of the cross-sectional enlarged portion 13 can be made smoother. It becomes possible to do.

  The housing 20 is made of an insulating material such as synthetic resin, and is formed in a shape that defines a plurality of terminal insertion holes 22 and anticorrosive body accommodation spaces 24 as shown in FIG. The terminal insertion holes 22 extend in parallel with each other along the front-rear direction (left-right direction in FIG. 7) of the connector, and the electrical contact portions 12 of the terminals 10 extend along the axial direction of the terminals 10 from the rear end side. It is possible to be inserted. In front of each terminal insertion hole 22, a terminal through which a male electrical contact portion, a so-called tab, is inserted from the outside to be inserted into the female electrical contact portion inserted into the terminal insertion hole 22. An insertion hole 23 is formed.

Further, the housing 20 has lances 26 at positions where the electrical contact portions 12 of the terminals 10 inserted into the terminal insertion holes 22 are locked. In this embodiment, each of the electrical contact portions 12 is formed with a locked piece 17 projecting downward from its bottom surface, while each lance 26 is connected to the locked piece 17 when the electrical contact portion 12 is inserted. To be retracted from the locked piece 17 to allow the passage of the locked piece 17, and after the passage, that is, after the insertion of the electric contact portion 12 is completed, the elastic return is performed and It has a tongue-like shape for locking the locked piece 17 from the rear.

  The anticorrosive body accommodating space 24 is located behind the terminal insertion holes 22 (on the right side in FIG. 7) and extends over the terminal insertion holes 22, in other words, all the terminal insertion holes as viewed from the rear. 22 in shape. In this embodiment, a plurality of terminal receiving holes 28 corresponding to the terminal insertion holes 22 are also provided on the rear side of the anticorrosive body accommodation space 24. In other words, the anticorrosive body accommodating space 24 is formed so as to cross the terminal insertion hole 22 and the terminal receiving hole 28 arranged in the terminal axis direction in a direction perpendicular to the terminal axis direction. Further, the position of the anticorrosive body accommodating space 24 is such that the electric wire crimping portion 14 of the terminal 10 is in a state where the electric contact portion 12 of each terminal 10 is inserted into the terminal insertion hole 22 (in the present invention, at least the electric wire crimping portion in the present invention). The contact portion between the wire and the conductor of the electric wire is set so as to be located in the anticorrosive body accommodating space 24.

  The anticorrosive body 30 is made of a gel-like body and is accommodated in the anticorrosive body accommodating space 24. The gel body constituting the anticorrosion body 30 retains the outer shape corresponding to the anticorrosion body housing space 24 (in this embodiment, a substantially rectangular parallelepiped shape) before the terminals 10 are inserted, and the anticorrosion. While having a shape retaining property that can be accommodated in the body accommodating space 24 without leakage, the electrical contact portions 12 of the terminals 10 penetrate the anticorrosion body 30 and are inserted into the terminal insertion holes 22 corresponding to the electrical contact portions 12. In the state where the insertion is completed and the wire crimping portion 14 of the terminal 10 and the conductor 52 of the electric wire 50 to which the terminal 10 is crimped are wrapped, moisture in the contact portion between the wire crimping portion 14 and the conductor 52 is covered. Viscosity is sufficient to prevent the intrusion. Specifically, silicone gel, acrylate gel, urethane gel, olefin-based gel and the like are suitable as this gel-like body.

  In this embodiment, in the assembly of the terminal 10 and the electric wire 52, the portions before and after the contact portion are in close contact with the anticorrosion body 30 over the entire circumference thereof, so that the contact portion within the anticorrosion body 30 is formed. Sealing is achieved. Specifically, in the region on the front side of the contact site, the outer peripheral surface of the cross-sectional enlarged portion 13 having a cross section larger than the contact site is in close contact with the anticorrosive body 30, and in the region on the back side of the contact site, The electric wire 50 located immediately behind the rear end of the terminal 10 is in close contact with the anticorrosion body 30 over the entire circumference.

  The retainer 40 is attached to the housing 20 in order to double-lock the electrical contact portions 12 inserted into the terminal insertion holes 22. Specifically, as shown in FIGS. 7 and 10, an insertion allowable position (temporary locking position) that allows insertion of the electrical contact portion 12 into each terminal insertion hole 22, and a position above the insertion allowable position. The electrical contact so as to prevent detachment of the electrical contact portion 12 from the terminal insertion hole 22 in a state where the electrical contact portion 12 is inserted into the terminal insertion hole 22 as shown in FIG. It attaches to the said housing 20 so that it can move between the latching positions (main latching position) which latch the part 12. FIG.

  The retainer 40 includes a bottom wall 42, left and right side walls 44 that rise from the left and right sides of the bottom wall 42, and a terminal locking portion 46 that is positioned in front of the side walls 44. A locked protrusion 45 that protrudes inward is formed at the upper end of the side wall 44, and a temporary locking protrusion 25 </ b> A that protrudes outward and a temporary locking protrusion 25 </ b> A on the left and right outer surfaces of the housing 20. And a main locking projection 25B that protrudes outward at a position immediately above. The temporary locking protrusion 25A is provided at a position where the retainer 40 is temporarily locked to the insertion allowable position by engaging with the locked protrusion 45 from below, and the final locking protrusion 25B. Is provided at a position where the retainer 40 is fully locked at the locking position by engaging with the locked protrusion 45 from below.

  The terminal locking part 46 has a plurality of locking protrusions 46 a corresponding to the terminal insertion holes 22. As shown in FIGS. 7 and 10, these locking projections 46 a are immersed below the bottom surface of the terminal insertion hole 22 when the retainer 40 is in the insertion allowable position, and are electrically contacted with the terminal insertion hole 22. 12, while the retainer 40 is raised to the locking position as shown in FIG. 1, the terminal insertion hole 22 protrudes above the bottom surface of the terminal insertion hole 22. The electrical contact portion 12 inserted into the is constrained from the rear side to prevent its removal.

  Furthermore, for each position of the retainer 40, when the retainer 40 is in the insertion allowable position, the bottom wall 42 of the retainer 40 is provided with the anticorrosive body accommodating space 24 as shown in FIGS. The bottom wall 42 of the anticorrosive body 30 is separated from the inner anticorrosive body 30 while the retainer 40 is raised from the insertion allowable position to the locking position as shown in FIGS. The mounting position of the retainer 40 (the positions and the retainers described above) is pressed against the lower surface so that the anticorrosive body 30 is compressed vertically with the top wall of the housing 20 (the upper wall of the anticorrosive body accommodating space 24). Forty shapes are set.

  Next, an example of the procedure for using this connector and its operation will be described.

  1) The wire crimping portion 14 of each terminal 10 is crimped to the end of the corresponding wire 50. Specifically, the conductor barrel 15 of the electric wire crimping portion 14 is crimped to the conductor 52 exposed at the end of each electric wire 50, and the insulation barrel 16 is applied to the insulating coating 54 positioned immediately behind the conductor 52. Crimped. As described above, since the conductor 52 is made of aluminum and the entire terminal 10 including the conductor barrel 15 is made of copper or a copper alloy, moisture adheres to the contact portion between the conductor 52 and the conductor barrel 15. Then, the ionization of the electrically conductive aluminum conductor proceeds and the corrosion proceeds. This corrosion is suppressed by the anticorrosive body 30 described in detail later.

  2) On the other hand, in the housing 20, the anticorrosion body 30 can be loaded in the anticorrosion body accommodating space 24 of the housing 20 before the retainer 40 is mounted on the housing 20. After the loading, the retainer 40 is mounted on the housing 20. In the initial stage, the retainer 40 is temporarily locked at the insertion allowable position shown in FIGS.

  3) The electrical contact portion 12 of each terminal 10 is inserted into each terminal insertion hole 22 in the housing 20. Specifically, the electrical contact portion 12 is first inserted into the terminal receiving hole 28 at the rear end of the housing 20, and further penetrates the anticorrosive body 30 made of a gel-like body in the anticorrosive body accommodating space 24 before the terminal insertion hole. 22 is inserted. In a state where the insertion is completed, that is, in the state shown in FIGS. 10 to 12, each of the electrical contact portions 12 is primarily locked by a lance 26 corresponding to the electrical contact portion 12. The crimping part 14 and the terminal of the electric wire 50 to which it is crimped are in a state of being wrapped by the gel-like anticorrosive body 30 pierced by the electrical contact part 12.

Thus, the anticorrosion body 30 that wraps the wire crimping portion 14 and the end of the wire 50 effectively prevents moisture from entering the contact portion between the conductor barrel 15 in the wire crimping portion 14 and the conductor 52 in the wire 50. The corrosion at the contact site resulting from this (in this embodiment, in particular, the corrosion of the aluminum conductor 52) is efficiently and collectively inhibited. Since the anticorrosive body 30 protects the contact portion that is particularly required to prevent the ingress of moisture locally and comprehensively for all the terminals 10, the anticorrosive body 30 is provided in the housing like a conventional waterproof connector. Unlike those having a structure for completely eliminating the intrusion of moisture into the housing, the contact portions can be prevented from being corroded without significantly increasing the size of the housing or significantly increasing the cost.

  In particular, in this embodiment, portions of the assembly of the terminal 10 and the electric wire 50 before and after the contact portion (specifically, the cross-sectional enlarged portion 13 and the terminal 10 having a cross section larger than the contact portion). When the immediately adjacent electric wire 50) is in close contact with the surrounding anticorrosive body 30 over the entire circumference, sealing of the contact portion in the anticorrosive body 30 is achieved.

  4) After the insertion of each terminal 10 is completed, the retainer 40 is pushed up from the insertion allowable position toward the locking position. As a result, the locked protrusion 45 of the retainer 40 shifts from the previous position, that is, the position engaged with the temporary locking protrusion 25A, to the position engaged with the main locking protrusion 25B. The main locking is performed at the locking position shown in FIGS. The terminal locking portion 46 of the retainer 40 in this locking position is such that all the locking projections 46a included in the terminal locking portion 46 restrain the rear end of each electrical contact portion 12 from the rear, 10 is secondarily locked together. At that time, the bottom wall 42 of the retainer 40 compresses the anticorrosion body 30 in the vertical direction together with the top wall of the housing 20, thereby increasing the degree of adhesion between the wire crimping portions 14 and the electric wires 50 and the anticorrosion body 30. Thus, the function of the anticorrosive body 30 to prevent moisture from entering the contact portion between the wire crimping portion 14 and the conductor 52 of the wire 50 is enhanced. Specifically, even if the anticorrosion body 30 has a high viscosity and there are some gaps between the anticorrosion body 30 and the terminals 10 and the electric wires 50, the compression of the anticorrosion body 30 fills the gap. Or reduced. Thereby, the degree to which the penetration | invasion of the water | moisture content from the outside to the said electric wire crimping part 14 or the said conductor 52 is raised.

  In the present invention, the retainer 40 is not indispensable and can be omitted as appropriate according to the specification. Further, the shape and size of the anticorrosion body 30 can be freely set within a range in which the contact portion between the wire crimping portion 14 and the conductor 52 of the wire 50 can be covered and protected. It may be set according to the number or arrangement of.

  In addition, the connector according to the present invention only needs to include at least a terminal made of a metal different from the conductor of the electric wire to which the terminal is mounted, and excludes a terminal including a terminal not corresponding to this. is not. For example, the connector according to the present invention includes a plurality of terminals made of a metal different from a conductor constituting an electric wire to be attached (for example, a plurality of terminals made of copper or a copper alloy attached to an electric wire having an aluminum conductor), and You may have a terminal which consists of the same metal as the conductor which comprises the electric wire which should be mounted | worn (For example, the terminal made from copper or a copper alloy with which the electric wire which has a copper or copper alloy conductor is mounted | worn).

  Moreover, when the shape-retaining property of the gel-like body constituting the anticorrosive body according to the present invention is relatively high, the anticorrosive body has a slit penetrating through it along the axial direction of the terminal, and along this slit The electrical contact portion of the terminal may be inserted. The slit suppresses the terminal from being shaken in the width direction of the slit when the terminal is inserted into the slit, thereby exhibiting a function of guiding the terminal to the corresponding terminal insertion hole and Make the insertion work easier.

  Specifically, for example, as shown in FIG. 14, the slits may be a plurality of slits 32 formed in parallel to each other (in the horizontal direction in the figure), or as shown in FIG. Further, the slits 34 may be formed in a cross shape at positions corresponding to the insertion positions of the respective terminals (that is, formed in a plurality of directions intersecting each other). The former slit 32 can suppress shaking in the width direction (vertical direction in FIG. 14) of the slit 32 with respect to the terminal inserted into the slit 32, and the latter slit 34 has each slit 34. Each of the slits 34 can be prevented from shaking in a plurality of width directions (vertical direction and horizontal direction in FIG. 15).

  Alternatively, as shown in FIG. 16, the anticorrosive body 30 is divided into a plurality of (three in FIG. 16) blocks 30a, 30b, and 30c, and the blocks 30A, 30B, and 30C are combined to be adjacent to each other. A slit may be formed between each other. The block may be divided into a plurality of different directions (for example, the up-down direction and the left-right direction in FIG. 16), and in that case, a plurality of intersecting ones are provided in the same manner as the slit 34 shown in FIG. It is possible to form slits extending in the direction.
