Description

  The present invention relates to a low-fitting connector that allows a male connector or a female connector, at least one of which is composed of a plurality of connectors, to be fitted or released simultaneously by a lever turning operation.

  Many structures have been disclosed for a so-called lever-type low-fitting connector that has a connector structure that holds a lever and that allows the one connector to be fitted to the other connector with a low fitting force by rotating the lever. (For example, Patent Document 1).

  Also, in order to cope with the increase in the number of connection points and the high functionality of vehicles and the like in which these connectors are used, after holding multiple connectors on a holder with levers, the levers can be turned together to rotate the other party Many types of connectors that connect to connectors have been proposed (for example, Patent Document 2).

  However, the lever-type low-fitting connector as described in Patent Document 1 is formed with a lever holding projection or lock projection, a shaft for rotating the lever, etc. on the connector itself, so the structure of the connector is complicated, When it is desired to change the size of the connector by increasing or decreasing the number of connection points, the connector has to be redesigned, and there is a problem that the increase or decrease in connection points cannot be flexibly handled. In addition, since the lever is a separate part, there was a problem in labor and workability of parts management. Further, the lever-type low-fitting connector as described in Patent Document 2 can be flexibly adapted to increase / decrease of the connector because the connector is held by the holder, and the lever is also assembled to the holder. Although there is no problem, since the lever is formed in a bifurcated shape and both side plates of the lever are locked on both sides of the holder, there is a problem that the holder including the lever is enlarged.

  On the other hand, as shown in FIGS. 22 to 24, the inventors have a plurality of first connector holding portions 110 that hold the female connector 30, and a second connector holding portion 120 that holds a laminated connector (not shown). And a lever 200 attached to the connector holder. The lever 200 is pivotally supported by a lever receiving groove 140 formed at the center in the width direction of the connector holder 100, and a plurality of connector holding portions are provided. There has been proposed a lever-type low-fitting connector that is provided in a connector holder so as to sandwich a lever, and that can be fitted to a mating connector by rotating the lever 200 (Japanese Patent Application No. 2004-183060). This lever-type low-fitting connector cannot be flexibly adapted to the increase / decrease in the number of connection points, as in Patent Documents 1 and 2, and the problem that the holder including the lever is enlarged because the lever is not bifurcated. Has been resolved.

  However, in the previously proposed lever-type low-fitting connector, as shown in FIGS. 22 to 24, after the female connector 30 is held in the connector holder 100, it is connected to the mating connector (not shown). Therefore, when the lever 200 is rotated, the electric wire 400 becomes an obstacle, and the lever cannot be rotated unless the electric wire 400 is scraped. In this case, in addition to the trouble of scraping the electric wire, when the electric wire is straightened, there is a possibility that the habit of the scraping may remain and a problem such as occurrence of pre-length may occur.

  Further, in the previously proposed lever-type low-fitting connector, the order in which the laminated connectors are assembled to the second connector holding portion 120 is limited. That is, in the state of FIGS. 22 and 23, the lever 200 blocks the second connector holding portion 120, and the laminated connector cannot be inserted into the second connector holding portion 120. After scraping and moving the lever 200 to the position shown in FIG. 24, a laminated connector (not shown) was inserted into the second connector holding portion 120. The existence of such process restrictions has a concern of increasing process management costs.

  An object of the present invention is to provide a lever-type low-fitting connector for fitting a plurality of connectors to a mating connector at a time via a lever so that the electric wire does not interfere with the rotation of the lever when the lever is rotated.

  Hereinafter, the lever type low fitting connector 1 concerning one embodiment of the present invention is explained based on a drawing. A lever-type low-fitting connector 1 according to an embodiment of the present invention includes a female connector 30 and a laminated connector 40, a connector holder 10 that can hold the female connector 30 and the laminated connector 40, and a connection to the connector holder 10. It consists of a lever 20 assembled in a movable manner, and a single male connector 50 that can be fitted to a plurality of female connectors 30 and laminated connectors 40.

  Each of these components will be described in detail below. First, the connector holder 10 will be described. 1 to 3 are perspective views showing the connector holder 10. 2 shows the surface of FIG. 1 cut along line AA, and FIG. 3 shows the surface of FIG. 1 cut along line BB.

  The connector holder 10 is made of a sufficiently strong resin material that is easy to mold during manufacture and can be used for a long period of time, and holds a pair of first connectors arranged in parallel so that two female connectors 30 can be attached. Part 11 and a second connector holding part 12 to which one laminated connector 40 can be attached. In addition, a lever housing groove 14 capable of housing a lever 20 described later is formed in the central portion of the pair of first connector holding portions 11, and a single plate-like lever 20 can be attached to this portion. ing.

  As shown in FIG. 2, a boss 14a for assembling the lever 20 protrudes from one wall portion inside the lever receiving groove 14 at the center of the wall portion, and the lever slides on the side of the boss 14a. Is provided with a lance 14b that prevents the lever 20 from rotating at a position spaced apart by a certain distance in the opposite direction. One end of the lance 14b has a cantilever shape separated from the holder body, and is provided with a tapered surface 14c and a locking projection 14d whose thickness decreases toward the side away from the holder body. As will be described later, the lance 14b is used to house the lever 20 in the lever housing groove 14 and to restrict the movement of the lever. The lever receiving groove 14 is provided with a stopper 14e that restricts the rotation of the lever and prevents the lever from falling off.

  Further, since a plurality of connectors are fitted to the male connector 50, the two connector holders 10 are in the male connector 50 in the left and right reversed state between the first connector holding portion 11 and the second connector holding portion 12. A holder misbonding prevention groove 15 for preventing misbonding is formed. The holder miscoupling prevention groove 15 is formed from one side of the connector holder 10 toward the center of the connector holder 10. Further, a fitting temporary locking piece 15a is formed in the holder miscoupling prevention groove 15, so that the connector holder 10 can be temporarily locked to the male connector 50 when the connector holder 10 is inserted into the male connector 50 described later.

When this is done, the connector engaging projection 17 acts as a retainer on the female connector 30. That is, if the terminal is left half inserted into the female connector 30, the female connector 30 cannot be completely inserted into the first connector holding portion 11 of the connector holder 10, and the terminal half insertion state into the female connector 30 is detected. It is like that. Further, the first connector holding portion 11 is formed with a pair of holder locking pieces 11 a for locking the female connector 30 inserted into the connector holding portion 11.

  On the other hand, also in the second connector holding portion 12, convex portions 12a that allow a laminated connector 40 to be described later to be inserted in an aligned state are formed on the inner wall surface of the holding portion on both sides in the connector holding portion arrangement direction. . In addition, a holder locking piece 12 b for locking the laminated connector 40 inserted into the second connector holding portion 12 is formed on the inner wall surface of the second connector holding portion 12.

  In addition, a misassembly prevention rib 12c that prevents misassembly of a laminated connector 40 described later is formed inside the second connector holding portion 12.

  Next, the structure of the lever 20 will be described. 4 is a perspective view of the lever 20, and FIG. 5 is a perspective view of the lever 20 of FIG. 4 viewed from the opposite side. The lever 20 is also made of a sufficiently strong resin material that can be easily molded at the time of manufacture and can be used for a long period of time. The lever 20 includes a finger-shaped portion 21 at one corner and a substantially rectangular plate-like portion 20a. A rotation shaft hole 22 is formed near the center of the shaped portion 20a, and the boss 14a of the connector holder 10 is engaged with the rotation shaft hole 22. Then, in a state where the boss 14a of the connector holder 10 is engaged with the rotation shaft hole 22, this engaging portion becomes an action point when the lever 20 is considered as a lever.

  Further, the lever 20 is formed with a temporary locking hole 22a that is connected to the rotation shaft hole 22 and has the same size as the rotation shaft hole 22, and is inserted or inserted when the female connector 30 is inserted into the connector holder 10. Previously, the temporary locking hole 22a and the boss 14a are engaged. The lever 20 has a slide groove 23 connecting the temporary locking hole 22 a and the rotation shaft hole 22. The slide groove 23 has a slide groove opening 23a at the end portion on the temporary locking hole 22a side, and a chamfer 23b is formed so that the boss 14a can be easily inserted. The slide groove 23 is linearly formed with the same width as the diameter of the rotary shaft hole 22 and the temporary locking hole 22a, and is formed so as not to penetrate the plate-like portion 20a on both side surfaces of the plate-like portion 20a. Has been.

  On the other hand, a notch is formed as a connector low fitting groove 24 in a part of the lever periphery. The connector low-fitting groove 24 meshes with a low-fitting cam protrusion 51a of a male connector 50 described later, and by rotating the lever 20, the plurality of female connectors 30 and the laminated connector 40 are moved to the male connector side together with the connector holder 10. It plays the role of mating connectors with low mating force. That is, when the lever 20 is considered as a lever, a portion where the connector low fitting groove 24 and the low fitting cam protrusion 51a mesh with each other serves as a fulcrum. In addition, a plurality of protrusions 21a are formed in parallel on the finger hanging portion 21 to prevent the slipping of the fingers when the lever is rotated. When the lever 20 is considered to be a lever, the finger hook portion 21 corresponds to a power point. In addition, a flexible lever lock piece 25 for locking the lever 20 to the male connector 50 at the end of connector fitting is formed immediately below the finger hook portion 21, and a part of the lever lock piece 25 is formed. A lever lock claw 26 is formed.

  A lever arcuate protrusion 27 and a lever angular protrusion 28 are formed on a part of the lever periphery. The lever arcuate protrusion 27 and the lever angular protrusion 28 play a role of regulating the movement of the lever in cooperation with the lance 14 b provided on the connector holder 10.

  Next, the female connector 30 that is a connector inserted into the first connector holding portion 11 of the connector holder 10 and that requires a relatively large fitting force with the male connector 50 will be described. FIG. 6 is a perspective view of the female connector 30, and FIG. 7 is a perspective view showing the female connector 30 from the opposite side of FIG. The female connector 30 is also made of a sufficiently strong resin material that is easy to mold during manufacture and can be used for a long period of time, has a thin rectangular parallelepiped shape, and has a terminal housing portion arranged in parallel and a terminal insertion on one end face A plurality of openings 30a are formed in parallel, and a terminal insertion port (not shown in FIGS. 6 and 7) of the male connector 50 is formed on the side opposite to the terminal insertion opening 30a. As shown in FIG. 7, a flexible cantilever-shaped housing lance (terminal insertion detection piece) 31 is formed in parallel on the side of the female connector 30. A terminal (not shown) attached to () is inserted from above in FIGS. 6 and 7, and a part of the terminal is locked by the housing lance 31. When the female connector 30 is inserted into the first connector holding part 11 of the connector holder 10, the connector engaging convex part 17 formed on the connector holder 10 reaches a position where it overlaps the housing lance 31. When the terminal is correctly inserted into the female connector 30, the housing lance 31 maintains a normal bending state, and the housing lance 31 is correctly engaged with the connector engaging convex portion 17. On the other hand, when the terminal is half inserted into the female connector 30, the housing lance 31 is abnormally bent and the housing lance 31 does not engage with the connector engaging convex portion 17, whereby the terminal is completely or incompletely inserted into the female connector 30. Can be confirmed.

  Further, engaging portions 32 with the connector holder 10 are formed on both side surfaces of the female connector 30, and the engaging portions 32 and the holder locking pieces 11a (see FIG. 3) of the connector holder 10 cooperate to form a female connector. 30 is locked to the connector holder 10.

  Subsequently, the laminated connector 40 inserted into the second connector holding portion 12 of the connector holder 10 will be described with reference to FIGS. 8 and 9 are connectors 42 that are stacked above the second layer, and FIG. 10 is a perspective view showing a connector 41 that is assembled to the outermost layer of the plurality of connectors shown in FIGS. 8 and 9. It is. 9 is a perspective view of the connector 42 of FIG. 8 as viewed from the opposite side. FIG. 11 is a perspective view showing a laminated connector 40 in which connectors 41 and 42 are laminated. Each of the connectors 41 to 42 constituting the laminated connector 40 is made of a sufficiently strong resin material that is easy to be molded at the time of manufacture and can be used for a long time, has a thin rectangular parallelepiped shape, and has terminal accommodating portions arranged in parallel inside. In addition, a female connector terminal insertion opening 40a is formed on one end face, and a male connector terminal insertion port 40b is formed on the opposite side of the female connector terminal insertion opening 40a. The laminated connector 40 allows the terminals 42 and connectors 41 to be laminated after the wiring harness terminals (not shown) are inserted into the respective connectors 42 before lamination so that the terminals can be multipolarized. Yes.

  Each connector has a secondary locking projection 40c (see FIG. 9) and a secondary locking insertion hole 40d (see FIG. 8), which are adjacent to each other at the stage of stacking the connectors 41 and 42. The secondary locking protrusions 40c and the secondary locking insertion holes 40d of the connectors 41 and 42 are engaged with each other. Each connector is provided with an interlayer lock 40e (see FIG. 9) and an interlayer lock engaging portion 40f (see FIG. 8), and the interlayer lock 40e of adjacent connectors overlapping each other at the stage of stacking the connectors 41 and 42. And the interlayer lock engaging portion 40f are engaged with each other.

  In stacking each connector 41, the connector 41 shown in FIG. 10 is the first layer, and a required number of connectors 42 shown in FIGS. 8 and 9 are stacked thereon, and a lid 43 is assembled on the opposite side of the connector 41. The laminated connector 40 is completed. Further, the lid 43 and the first-layer connector 41 are formed with an incorrect assembly prevention piece 40g. This is because when the laminated connector 40 is inserted into the second connector holding portion 12 of the connector holder 10, the direction of the laminated connector 40 is rotated by 180 degrees, for example, and it is not noticed that it is misassembled. Is preventing. The misassembly prevention pieces 40g are formed at three corners of the multilayer connector 40 in a direction perpendicular to the terminal insertion direction of the multilayer connector 40, and are misassembled in the second connector holding portion 12 of the connector holder 10. When the attachment prevention rib 12c is formed and the assembly direction is wrong, one of the three erroneous assembly prevention pieces 40g of the multilayer connector 40 abuts to prevent the insertion of the multilayer connector 40. Yes. When properly assembled, the corner portion of the laminated connector 40 where the erroneous assembly preventing piece 40g is not formed corresponds to the location of the erroneous assembly preventing rib 12c, and insertion is not hindered. Thereby, the incorrect assembly | attachment of the laminated connector 40 can be prevented.

  Next, the male connector 50 will be described. FIG. 12 shows a perspective view of the male connector 50. The male connector 50 is also made of a sufficiently strong resin material that is easy to mold during manufacture and can be used for a long time, has a thin rectangular parallelepiped shape, and a connector holder insertion portion in which two connector holders 10 can be inserted in a predetermined arrangement Two 51 are formed side by side in the width direction of the male connector 50. The male connector 50 is formed with an incorrect connection preventing wall 52 in each connector holder insertion portion 51 for preventing the connector left and right erroneous connection when the connector holder 10 is inserted into the male connector 50. As a result, if the incorrect connection prevention wall 52 and the holder incorrect connection prevention grooves 15 formed in different shapes on the left and right connector holders 10 do not match, the connector holder 10 in which the female connector 30 and the laminated connector 40 are inserted is correctly set. It cannot be inserted into the male connector 50 side by side.

  Further, the connector holder insertion portion 51 of the male connector 50 is provided with a low fitting cam projection 51 a on one side wall thereof, and the low fitting cam projection 51 a is rotated by turning the lever 20. The lever 20 is engaged with the connector low fitting groove 24, and further, the lever 20 is further rotated so that the meshed portion becomes a fulcrum of a so-called lever, and the connectors are fitted with a low fitting force. .

  A plurality of terminal insertion holes 51b into which male terminals can be inserted are formed side by side on the bottom surface of the male connector 50, and a convex wall 51c for preventing terminal twisting is formed. A lock claw engagement portion 55 is formed on the inner wall of the connector holder insertion portion 51, and a temporary locking release piece 56 is formed. Further, a fitting temporary locking groove 57 is formed in the erroneous coupling preventing wall 52.

  In the present embodiment, as described above, a structure is shown in which two connector holders 10 to which the female connector 30 and the laminated connector 40 are attached can be assembled to the male connector 50. However, it goes without saying that it is not necessary to limit the two connector holders 10 to which the female connector 30 and the laminated connector 40 are attached to the male connector 50 in this way.

  Next, a method of assembling the lever type low fitting connector 1 having such a structure and fitting the connectors together will be described. First, as shown in FIG. 13, the lever 20 is assembled in the lever receiving groove 14 of the connector holder 10. In this assembly, the lever 20 is inserted from the opening (on the left side in FIG. 13) of the lever receiving groove 14 of the connector holder 10, but is inserted between the locking projection 14d of the lance 14b and the stopper 14e. When the lever 20 is housed in the lever housing groove 14, the downward movement (downward direction in FIG. 13) of the lever 20 is restricted by the angular protrusion 28 coming into contact with the locking protrusion 14d. The movement of the lever 20 in the direction of pulling out the lever 20 (the left direction in FIG. 13) is restricted by the engagement of the stop hole 22a and the boss 14a of the connector holder 10, and the stopper 14e moves upward in the lever 20 The movement (upward direction in FIG. 13) and the movement in the rotating direction (clockwise direction in FIG. 13) are restricted. In this state, the boss 14a enters from the slide groove opening 23a of the slide groove 23, the temporary locking hole 22a and the boss 14a are engaged, and the lever 20 is temporarily locked to the connector holder 10. It has become. When the lever 20 is assembled in the lever receiving groove 14 of the connector holder 10 as described above, the lever 20 cannot be detached from the connector holder 10 unless the lance 14b is operated with a tool or the like. And the management cost of the number of parts is reduced.

  FIG. 14 is a perspective view showing a state in which the lever 20 is attached to the connector holder 10, and FIG. 15 is a perspective view of FIG. 14 cut out along the line CC and seen from the side opposite to FIG. 14. 14 and 15 are in a lever temporary locking state, and in this state, the female connector 30 and the laminated connector 40 can be inserted into the connector holder 10. That is, in the conventional lever-type low-fitting connector shown in FIGS. 22 to 24, the laminated connector is not connected to the second connector holding portion unless the female connector is inserted into the connector holder and the lever is moved to a predetermined position. However, in this embodiment, it is possible to insert the female connector 30 and the laminated connector 40 from either one without any restriction.

  Subsequently, an operation of inserting the two female connectors 30 into the connector holder 10 will be described. Prior to inserting the two female connectors 30 into the connector holder 10, the terminals of the wire harness are inserted into the female connector 30 in advance. Here, the housing lance 31 maintains a normal state when the terminals are completely inserted into the female connector 30. As a result, as shown in FIGS. 16 and 17, when all the terminals are completely inserted into the female connector 30, when the female connector 30 is inserted into the first connector holding portion 11 of the connector holder 10, the connector holder The connector engaging projection 17 as a front retainer 10 is engaged with the housing lance 31 in a normal state, and the female connector 30 can be inserted into the connector holder 10 to a predetermined position. On the other hand, if the female connector 30 has at least one terminal that is incompletely inserted, the connector engaging projection 17 formed on the connector holder 10 and the housing lance 31 of the female connector 30 interfere with each other. The first connector holding part 11 of the holder 10 cannot be completely inserted to a predetermined position. Thereby, it can be easily confirmed from the outside whether all the terminals are completely inserted into the female connector 30 or at least one terminal is incompletely inserted.

  18 to 20, after inserting the female connector 30 into the first connector holding portion 11 of the connector holder 10 and the laminated connector 40 (not shown) into the second connector holding portion 12, the lever 20 is moved forward ( FIG. 18 shows the state of being pushed into the right side). FIG. 20 is a perspective view of FIG. 19 taken along the line DD and viewed from the side opposite to FIG.

  In this state, the boss 14a passes through the slide groove 23 from the engagement state between the boss 14a formed in the connector holder 10 and the temporary locking hole 22a of the lever 20, so that the boss 14a passes through the slide groove 23 and rotates. The state is engaged with the hole 22. Further, when the lever-shaped projection 28 abuts against the locking projection 14d, the downward movement of the lever 20 (the downward direction in FIG. 18) is restricted, and the stopper 14e moves upward. (Upward direction in FIG. 18) and movement in the rotating direction (clockwise direction in FIG. 18) are restricted.

  Next, the low-fitting operation of the male / female connector using the lever 20 will be described. When the connector holder 10 to which the female connector 30 and the laminated connector 40 are attached is inserted into the male connector 50 as described above, the provisional temporary locking groove 57 (see FIG. 12) of the male connector 50 and the provisional engagement of the connector holder 10 The stop piece 15a (see FIG. 3) is engaged, and the lance 14b of the connector holder 10 is bent and deformed by the temporary locking release piece 56 (see FIG. 12) formed inside the wall of the male connector 50, so that the lever angle of the lever 20 is increased. The temporary locking is released when the protrusion 28d does not abut against the locking protrusion 14d of the connector holder 10. Thereby, the lever 20 can be rotated. Thereafter, the finger hooking portion 21 is pressed against the male connector side and rotated so as to press the lever 20 in the insertion direction of the connector (in the direction of the arrow in FIG. 21), whereby the boss 14a acts as the lever action point and the finger hooking portion 21 acts as the power point. The lever 20 rotates with the connector low fitting groove 24 as a fulcrum. At this time, since the distance between the boss 14a and the finger hooking portion 21 is smaller than the distance between the connector low fitting groove 24 and the finger hooking portion 21, the female connector 30 having a large number of terminals and the laminated connector 40 are connected to each other. Thus, the male connector 50 can be fitted at a time with a low fitting force. Then, by engaging the lever lock claw 26 (see FIG. 5) with the lock claw engaging portion 55 (see FIG. 12) of the male connector 50, all fitting operations are completed.

  When the male female connector once fitted is released, the lever lock claw 26 of the lever 20 and the lock claw engagement portion 55 of the male connector 50 are released by operating the lever lock piece 25 of the lever 20. After that, the lever 20 may be rotated in the opposite direction to that when the lever 20 is fitted. Accordingly, the plurality of female connectors 30 and the laminated connector 40 can be released from the male connector 50 at a low fitting force at a time based on the above-described lever principle. After the plurality of female connectors 30 and the terminals of the laminated connector 40 and the terminals of the male connector 50 are disengaged, the male connector 50 is pulled away from the connector holder 10 and the lever 20 is slid to the position shown in FIG. The connector fitting release operation can be easily performed by removing the female connector 30 and the laminated connector 40 from the connector holder 10 in this state.

  As described above, in addition to the fact that the plurality of connectors 30 and 40 can be simultaneously fitted with a low fitting force by the rotation of the lever 20 attached to the connector holder 10, the lever type according to this embodiment is used. The low mating connector 1 is such that when the lever is pivoted, the electric wire does not obstruct the pivoting of the lever, facilitating the fitting work, and the female connector 30 and the laminated connector 40 are not restricted in order, and the connector holder Can be installed on.

  Further, by forming the connector engaging convex portion 17 having a retainer function in the connector holder 10, the number of parts can be reduced as compared with a method in which a retainer is directly fitted like a conventional connector. .

In addition, by providing a single-plate lever in the center of the connector holder, the connector width can be reduced compared to conventional connectors with levers that straddle both sides of the connector. Similarly, the width of the side connector can be reduced, and the overall size of the connector can be reduced.

  In the above-described embodiment, the configuration is such that a plurality of female connectors are inserted into the connector holder, and then the connector holder is inserted into the male connector and the connectors are fitted to each other with a lever. Instead, a plurality of male connectors may be inserted into the connector holder, and then the connector holder may be inserted into the female connector and the connectors may be fitted together with a lever.
