Description

  The present invention relates to a connector.

As a connector, a lever-type connector described in Patent Document 1 is known. This includes a pair of connectors that can be fitted to each other, and a lever is supported on one of the connectors so as to be rotatable about a support shaft. The lever is formed in a gate shape as a whole by an operating portion and a pair of left and right arm portions projecting from both ends thereof, and a cam groove and a shaft hole for a support shaft are formed in both arm portions. On the other hand, the other connector is provided with a cam follower. When the two connectors are fitted, the lever is set to the initial position and the cam follower enters the cam groove of the lever. By rotating the lever toward the mating position, the two connectors are pulled toward each other by the cam action by the engagement of the cam groove and the cam follower to obtain a normal mating state. While the lever is rotated, the operation portion is pushed in an arc from one end side to the other end side in the width direction of one connector.

  By the way, when the connector is multipolar, if there is rattling between the mating areas of both connectors, the other end in the width direction of one connector is biased by the pushing force against the operation part and Although the fitting operation is advanced quickly, there is a discomfort for delaying the fitting operation with the other connector by applying a pulling force in the direction away from the other connector on the one end side in the width direction. For this reason, there is a concern that both connectors may take a posture inclined from the normal fitting posture, and that the fitting operation of both connectors is finished in a state where the inclined posture is taken.

  The present invention has been completed based on the above-described circumstances, and an object of the present invention is to reliably guide both connectors to a normal fitting state.

  As a means for achieving the above object, the invention of claim 1 is characterized in that a lever having a cam groove is provided between one of a pair of connectors fitted to each other between an initial position and a fitting position. The other connector is provided with a cam follower that can be engaged with the cam groove, and the two connectors are shallowly fitted while the cam follower is inserted into the cam groove of the lever at the initial position. In the connector in which the two levers are drawn together by the cam action due to the engagement of the cam groove and the cam follower by rotating the lever from the state to the fitting position, the lever includes: An operation portion is provided on one end side across the rotation center, and a hook portion is provided on the other end side across the rotation center, and the other connector is engaged with the hook portion. A functioning receiving portion is provided, and the hooking portion is in a state of being hooked on the receiving portion at an engaging position on the way to the fitting position of the lever, and the lever is further operated by pushing the operating portion. By moving the hook from the engagement position to the fitting position, the hooking portion pulls up the receiving portion in a direction opposite to the pushing direction with respect to the operation portion, and the fitting posture of the two connectors can be corrected. It is characterized by the configuration described above.

  According to a second aspect of the present invention, in the first aspect of the present invention, the lever is formed in a gate shape as a whole by the operation portion and a pair of arm portions protruding from both ends thereof, and straddles the one connector. The hooking portion is recessed in the both arm portions, the receiving portion is protruded on both side walls of the other connector, and the receiving portion enters the hooking portion to be hooked. It is characterized in that the hanging state is constructed.

  According to a third aspect of the present invention, in the one according to the first or second aspect, the one connector is provided with a guide portion extending along a fitting direction of the two connectors, and the other connector is provided with: While the guide receiving portion is provided and the lever is rotated from the initial position to the engaging position, the fitting operation of the two connectors is guided by sliding the guide portion and the guide receiving portion relative to each other. It is characterized by the configuration.

<Invention of Claim 1>
When the operating part is gripped and the lever is rotated from the initial position toward the fitting position, the operating part approaches one end side in the width direction of one connector. After that, when the lever reaches the engaging position, the hooking portion of the lever is hooked with the receiving portion of the other connector on the other end side in the width direction of one connector. When the operating part is further pushed toward the fitting position, the hooking part pulls up the receiving part in the direction opposite to the pushing direction with respect to the operating part, and the fitting posture of both connectors is corrected. Therefore, both the connectors can be reliably guided to the proper fitted state using the lever turning operation.

<Invention of Claim 2>
Since the hooking part is recessed in both arm parts of the lever and the receiving part is protruded on both side walls of the other connector, the hooking state between the hooking part and the receiving part is configured in good balance on both sides of the lever. A smoother fitting situation is realized.

<Invention of Claim 3>
While the lever is rotated from the initial position to the engaging position, the guide portion of one connector and the guide receiving portion of the other connector slide with each other to guide the fitting operation of both connectors, While rotating from the engagement position to the fitting position, the hooking portion of one connector and the receiving portion of the other connector are in the hooked state, so that the fitting operation of both connectors is guided. Therefore, a smooth fitting operation is always ensured while the fitting operation of both connectors proceeds.

  The rear holder 50 that prevents the sealing member 40 from coming off is formed in a substantially rectangular block shape by a synthetic resin material, and the female terminal fitting 30 and the electric wire W connected thereto are inserted through the electric wire at every position corresponding to the electric wire insertion hole 41. An insertion path 53 for passing through the hole 41 is provided. The insertion path 53 has an opening diameter that is the same as or slightly larger than the box portion 32 of the female terminal fitting 30, and is capable of loosely inserting the electric wire W connected to the female terminal fitting 30. Locking leg pieces 51 are formed so as to protrude forward from the upper and lower ends of the rear holder 50. The locking leg 51 has a length that covers the upper and lower surfaces of the sub-housing 11 after passing through the locking leg piece insertion hole 42 of the sealing member 40 from the rear, and a locking claw 51A formed at the tip of the locking leg piece 51A. The rear holder 50 is attached to the sub-housing 11 with the seal member 40 sandwiched between the sub-housing 11 by elastically locking to the stepped portions 13 provided on the upper and lower surfaces of the sub-housing 11. It is like that. In the case of the present embodiment, a range from one having upper and lower pairs of locking leg pieces 51 to three upper and lower pairs are prepared according to the size of each sub-connector 10.

  The rear holders 50 are connected in the alignment direction (width direction) with their side edges butted together, whereby the sub-connectors 10 are held together via the rear holder 50. Specifically, a concave portion (not shown) and a convex portion 55 are respectively provided on the opposing surfaces (side edges) of both rear holders 50 adjacent in the arrangement direction, and the side edges of both rear holders 50 adjacent to each other are arranged in the front-rear direction. The rear holder 50 is united in the disengagement restricted state by sliding it so that the concave portion (not shown) and the convex portion 55 are concavo-convexly fitted in an irregular state.

In addition, a pair of guided portions 59 that form rail grooves that extend in the width direction and open on both side surfaces are formed at both upper and lower end portions of both rear holders 50. When the guide portion 65 formed on the frame 60 slides on the guided portion 59, the rear holder 50 and thus the sub-connector 10 are inserted and guided into the frame 60.
On the upper and lower surfaces of the rear holder 50 in the sub-connector 10 that is finally inserted into the frame 60, lock portions 50B that can be elastically locked with the lock receiving portions 61 of the frame 60 are provided. The lock part 50 </ b> B protrudes from the upper surface of the cover wall 59 </ b> A that covers the guided part 59, and can be bent and deformed toward the guided part 59. Further, a protective wall 50H protruding forward from one side edge of the rear holder 50 is formed in the sub-connector 10 to be inserted last, and this protective wall 50H faces the exposed end surface of the sealing member 40 facing the insertion port 60A of the frame 60. The sealing member 40 is placed in a protected state by covering the surface.

  The frame 60 is also made of synthetic resin and has a flat frame shape as a whole, and is formed with an opening at the front surface and one side surface (the right side surface shown in FIG. 1). One side surface of the frame 60 is configured as an insertion port 60A, and the sub-connectors 10 can be sequentially mounted in the frame 60 through the insertion port 60A. A pair of support shafts 62 are provided on the outer surfaces of the upper and lower walls of the frame 60 so as to rotatably support the lever 70. The upper and lower walls of the frame 60 are recessed with cam follower entry grooves 77 that open in the front edge and extend in the front-rear direction. Further, the front edges are also located closer to the end than the cam follower entry groove 77. A pin entry groove 78 that is open and extends along the front-rear direction is recessed. A cam follower 95 enters the cam follower entry groove 77 and a pin 98 enters the pin entry groove 78 in a slidable manner.

  The frame 60 has one connector accommodating space 64 that can accommodate the sub-connectors 10 collectively without being partitioned by a partition wall, and extends in the width direction on the inner surfaces of both upper and lower walls to form a rail shape. A pair of guide portions 65 is provided. In addition, a pair of receiving walls 66 extending in parallel with the guide portion 65 are formed behind the guide portion 65 on the inner surfaces of the upper and lower walls of the frame 60, and the upper and lower walls of the frame 60 are inserted. In the vicinity of the mouth 60A, a substantially rectangular lock receiving portion 61 is formed penetrating in the thickness direction. In the frame 60, the front region with the receiving wall 66 as a boundary is a connector housing space 64, and the rear region is a wire housing space 67 for collectively housing the wires W drawn from the rear surface of the rear holder 50. . Further, the frame 60 includes a rear wall 68 that guides the electric wire W led out from each sub-connector 10 to the same side as the insertion port 60A.

  The sub-connectors 10 are slid and inserted into the frame 60 from the insertion port 60 </ b> A through the rear holder 50 while keeping the combined state. At this time, the guided portion 59 and the guide portion 65 are engaged in the front-rear direction, so that the sub-connectors 10 are positioned in the front-rear direction in the frame 60. When the sub-connector 10 to be inserted last is attached to the frame 60, the lock portion 50B of the rear holder 50 is elastically inserted into the lock receiving portion 61 of the frame 60, and thus the insertion port of each sub-connector 10 is inserted. The stopper from 60A is prevented. At this time, the side edge of the sub-connector 10 inserted first is abutted against the back wall 69 of the frame 60 so that further insertion operations are restricted.

  As shown in FIGS. 2 and 5, the lever 70 has a gate shape as a whole with the operation portion 72 and a pair of arm portions 73 protruding from both ends thereof, and penetrates substantially at the center of both arm portions 73. By allowing the support shaft 62 to pass through the formed bearing hole 76, both the arm portions 73 are mounted so as to straddle the frame 60 in a state of being rotatably supported by the support shaft 62. Both arm portions 73 are formed with cam grooves 71 that can engage with the cam followers 95 of the male sub-connector 90 in an arc shape. The cam groove 71 is configured to open only on the inner side surfaces of both arm portions 73 and the outer peripheral edge of both arm portions 73, and the outer side is closed by the outer side surfaces of both arm portions 73.

  The lever 70 includes an initial position where the operation portion 72 is disposed so as to be in contact with one side end portion (the right end portion shown in FIG. 2) of the rear wall of the frame 60, and the operation portion 72 on the other side of the rear wall of the frame 60. It is possible to displace between a fitting position arranged so as to be in contact with the side end (the left end shown in FIG. 2). Both arm portions 73 are formed with elastically deformable elastic arm pieces 75 that are bent and deformed. The claw portions of the elastic arm pieces 75 abut against the groove edges of the cam follower entry grooves 77 to hold the lever 70 in the initial position. It is supposed to be. When the release rib 97 provided on the male sub-connector 90 comes into contact with the tip claw portion 75A of the elastic arm piece 75 at the start of fitting of both the connectors F and M, the elastic arm piece 75 releases the release rib 97. The lever 70 is allowed to rotate by being bent and deformed in the unlocking direction while sliding on the surface 97A. When the lever 70 is rotated toward the fitting position with the cam follower 95 facing the entrance of the cam groove 71 of the lever 70, the cam follower 95 moves along the cam groove 71 and the cam action by both of them is caused. As a result, the connectors F and M are attracted to each other so as to be properly fitted. In addition, a pair of opening prevention walls 63 are provided in an arch shape on both the upper and lower walls of the frame 60 so as to surround the periphery of both arm portions 73, and the excess of both arm portions 73 when the connectors F and M are fitted together. Prevents widening deformation.

  In the substantially central portion of the operation portion 72 in the width direction (referring to the left-right direction in FIG. 5; hereinafter, the description of the structure of the lever 70 is the lower side of FIG. 5 is the front and the upper side of FIG. 5 is the rear). When the lever 70 reaches the fitting position, a lever lock portion 74 is formed which can be elastically locked to a lever lock receiving portion 84 protruding from one end portion of the rear wall of the frame 60. As shown in FIG. 4, the lever lock portion 74 is covered with a protective wall 74 </ b> A that extends in the width direction on the outer side in the thickness direction of the operation portion 72 and a protective wall 74 </ b> A on the inner side in the thickness direction of the operation portion 72. It consists of lever lock arms 74B, 74C, 74D. The lever lock arms 74B, 74C, 74D are connected to and latched by a latching portion 74B extending in the width direction, a pair of leg portions 74C projecting forward from both ends of the latching portion 74B, and the front ends of both leg portions 74C. The receiving portion 74D extends in parallel with the portion 74B and bends backward inward in the thickness direction, and the lever portion 74B, both leg portions 74C, and the receiving portion 74D surround the lever lock receiving portion. A locking hole 74 </ b> E that allows entry of the portion 84 is partitioned and formed. When the lever 70 reaches the fitting position, the lever lock receiving portion 84 is elastically fitted into the locking hole 74E, the latching portion 74B abuts on the outer wall of the lever lock receiving portion 84 in a wedge shape, and A lever lock receiving portion 84 is sandwiched between the stopping portion 74B and the receiving portion 74D, and the lever 70 is held in a rotation restricted state (see FIG. 3).

  The hook portions 79 having receiving grooves 79A into which the pins 98 provided on the male sub-connector 90 can enter at both ends of the arm portions 73 across the operation portion 72 and the bearing hole 76. Is formed. The receiving groove 79 </ b> A of the hook 79 has a form that opens only to the outer peripheral edge of the both arm portions 73 on the front side in the rotational direction of the lever 70 and the inner side surfaces of the both arm portions 73. At the same time as the cam groove 71. The hook 79 is configured to be able to hook the pin 98 as the lever 70 is rotated to the engagement position before the fitting position, and then the lever 70 reaches the fitting position. In the process, the pin 98 can be pulled up in the rotation direction of the lever 70.

Next, the effect of this embodiment is demonstrated. First, the seal member 40 is attached to the rear surface of the sub-housing 11, and the rear holder 50 is covered from the rear in that state. As a result, the rear holder 50 is attached to the sub-housing 11 with the seal member 40 interposed therebetween.
Subsequently, the retainer 35 is inserted shallowly into the sub-housing 11, and the female terminal fitting 30 connected to the electric wire W from the rear in that state is inserted into the cavity 12 through the insertion path 53 of the rear holder 50 and the electric wire insertion hole 41 of the seal member 40. It is inserted into the cavity 12 and is primarily locked by the lance 18 in the cavity 12. Thereafter, the retainer 35 is inserted deeply and the female terminal fitting 30 is secondarily locked.

  When the mounting operation of the female terminal fittings 30 is completed for all the sub-connectors 10, the adjacent rear holders 50 are then slid in the front-rear direction while fitting the concave portions (not shown) and the convex portions 55 together. Connect and hold each other in a detachment regulation state. When the pair of sub-connectors 10 are combined, the rear holder 50 of another sub-connector 10 is connected and held to one of the rear holders 50, and the sub-connectors 10 are sequentially combined in the alignment direction via the rear holder 50. In such a combined state, the guided portions 59 of the sub-connectors 10 are continuously connected on a straight line in the width direction.

  Next, the sub-connectors 10 in the combined state are sequentially inserted into the connector housing space 64 of the frame 60 through the insertion port 60A. At the start of insertion, the guided portion 59 of the sub-connector 10 positioned at the left end is fitted to the guide portion 65 of the frame 60, and each sub-connector 10 is pushed into the connector housing space 64 from that state. Then, each sub-connector 10 is inserted into the frame 60 while being guided by the guide portion 65, and the sub-connector 10 to be inserted first is attached to the rear wall 69 as each sub-connector 10 reaches the proper mounting position. At the same time, the lock portion 50 </ b> B provided on the sub-connector 10 inserted last is elastically locked to the lock receiving portion 61 of the frame 60. In addition, the electric wires W drawn from the sub-connectors 10 are collected and stored in the electric wire housing space 67 and drawn in a predetermined direction.

  When the assembly is completed, the male sub-connector 90 is loosely fitted to the corresponding sub-connector 10 from the front. Then, the cam follower 95 enters the cam groove 71 through the cam follower entry groove 77, and the release rib 97 also enters the cam follower entry groove 77 to push the elastic arm piece 75 in the unlocking direction. The locked state is released. Next, the operating portion 72 is picked and the lever 70 is rotated around the support shaft 62 to the fitting position side, whereby the operating portion 72 of the lever 70 is drawn in the width direction while drawing an arc from the right end side to the left end side of the frame 60. Displace greatly. As the lever 70 rotates, the cam follower 95 moves along the cam groove 71 and the cam action causes the male sub-connector 90 to be drawn toward the corresponding sub-connector 10, so that the hood 91 is moved into the frame 60. It enters and is externally fitted to the sub-housing 11. Then, the pins 98 of the male sub-connector 90 enter the pin entry grooves 78 of the frame 60 during the fitting of both the connectors F and M.

  Thereafter, as shown in FIG. 2, as the operation portion 72 of the lever 70 approaches the left end side, the pushing force against the operation portion 72 is biased toward the left end side of the frame 60, and the male end is formed on the left end side of the frame 60. The sub-connector 90 enters deeply into the frame 60. On the other hand, the male sub-connector 90 does not sufficiently enter the frame 60 on the right end side of the frame 60. Therefore, the male connector M descends toward the right end. There is a case of taking an oblique posture that becomes a gradient.

However, in the case of the present embodiment, when the lever 70 reaches the engagement position before reaching the fitting position, the hook portion 79 crosses over the pin entry groove 78 and the pin 98 is hooked. By applying a force to the operating portion 72 and turning the lever 70 toward the fitting position, the pin 98 in the hooked state is gradually fitted into the back side of the receiving groove 79A of the hooking portion 79. It has become. Then, when the pin 98 reaches the back end of the catching portion 79 receiving groove 79A and the rotation operation of the lever 70 further proceeds, the pin 98 is pulled up (fished up) forward in the fitting direction by the catching portion 79, and the frame 60 On the right end side, the fitting operation of both the connectors F and M proceeds at a stroke to correct the inclination of the male sub-connector 90. While the fitting operation of both the connectors F and M proceeds, the partition wall 92 of the hood portion 91 slidably enters between the opposing surfaces of the rear holder 50, and this also guides the fitting operation of both the connectors F and M. It has become so.
When the lever 70 reaches the mating position in this way, the rotation operation of the lever 70 is restricted by the elastic locking of the lever lock receiving portion 84 and the lever lock portion 74 in a state where the rear edge of the lever 70 is arranged substantially horizontally. (See FIG. 3). Moreover, both the connectors F and M are fitted at a normal depth, and the male and female terminal fittings 30 and 94 accommodated in the connectors F and M are connected so as to be conductive.

  In addition, as shown in FIG. 6, when the male connector M takes a slanting posture with a downward slope toward the left end in the process of fitting both the connectors F and M, a force is applied to the operating portion 72 to apply the lever. By pushing 70 into the mating position, the mating operation of both the connectors F and M proceeds at a stroke on the left end side of the frame 60. When the lever 70 reaches the mating position, the male sub-connector 90 is also the same. The fitting posture is corrected.

  As described above, according to the present embodiment, even when both the connectors F and M are inclined from the normal posture due to the turning operation of the lever 70, when the lever 70 reaches the engagement position, The hook portion 79 of the lever 70 is in a state where the pin 98 of the male sub-connector 90 is hooked, and the hook portion 79 pulls up the operation portion 72 in the fitting direction by further turning operation of the lever 70, so that both connectors F, M Therefore, the connectors F and M can be surely guided to the normal fitting state. In addition, since the hook portion 79 is recessed in both arm portions 73 of the lever 70 and the pin 98 is protruded on both the upper and lower walls of the hood portion 91, the hook portion 79 and the pin 98 are hooked on both sides of the lever 70. The hanging state is configured with a good balance, and a smooth fitting state is realized.

Next, Embodiment 2 of the present invention will be described with reference to FIG. The second embodiment is different from the first embodiment in that the guide portion 85 is provided on the inner surface of the frame 60 in the female connector F, but the other is the same as the first embodiment, and is the same as the first embodiment. The same reference numerals are given to the structural parts, and duplicate descriptions are omitted.

That is, the guide portion 85 is formed in a rib shape extending along the fitting direction of the connectors F and M from the inner surface front end of the upper and lower walls of the frame 60 toward the rear. The guide portion 85 is a valley 99 (corresponding to the guide receiving portion of the present invention, which corresponds to the guide receiving portion of the present invention, as shown in FIG. 7) at the start of fitting of both the connectors F and M. Reference) is entered to guide the fitting operation of both connectors F and M.
According to the second embodiment, when the fitting of both connectors F and M is started and the lever 70 has not reached the engagement position, the guide portion 85 enters the valley 99 between the hood portions 91 and slides. By doing so, the fitting operation of both the connectors F and M is guided, and thereafter, the fitting operation of both the connectors F and M is guided by the engagement of the hook portion 79 and the pin 98. Thus, the smooth fitting operation is always ensured while the fitting operation of both connectors F and M proceeds. In addition, by using the valley 99 between the hood portions 91, it is not necessary to provide a dedicated structure to be a guide receiving portion on the other side of the guide portion 85, so that the structure of the male connector M can be simplified.
