  As shown in FIG. 16, the outer surface of the housing main body 21 includes a pair of long side surface portions 24 along the width direction and a pair of short side surface portions 25 along the height direction. The housing main body 21 is formed with a pair of slide accommodating portions 26 bulging out on both long side surface portions 24 on both sides in the height direction across the cavities 23. The slide accommodating portion 26 has a bag shape with one end in the width direction opened, and is formed over substantially the entire long side surface portion 24. Further, the rear end surface of the slide accommodating portion 26 opens to the rear end surface of the housing main body 21 leaving a closing portion 27 at one end in the width direction. In this slide accommodating portion 26, an arm portion 62 (described later) of the slide type lever 60 can be accommodated in the fitted state through the opening 28 on one end side in the width direction.

  On the rear end surface of the housing main body 21, a pair of detection accommodating portions 29 are formed to bulge out at the other end in the width direction and at a position continuous with both the long side surface portions 24. The detection accommodating part 29 has comprised the bag shape which opened the width direction both ends. In addition, a communication portion 30 that communicates with the rear end opening of the slide housing portion 26 is formed at the front end of the detection housing portion 29, and the outer surface of the slide housing portion 26 and the outer surface of the detection housing portion 29 are stepped from each other. There is no continuous integration. In the detection accommodating portion 29, a detection main body portion 82 (described later) of the detection member 80 can be accommodated in the fitted state through the opening 31 on the other end side in the width direction.

  Further, as shown in FIG. 3, a temporary locking receiving portion 32 is formed in the rear end surface of the housing main body 21 so as to open to the wall surface of the detection accommodating portion 29 and is wider than the temporary locking receiving portion 32. On one end side in the direction, the main lock receiving portion 33 is formed to open in the detection accommodating portion 29. The temporary latch receiving part 32 opens to the communication part 30 at the other end in the width direction.

Further, a pair of windows 34 elongated in the width direction are formed on the rear end surface of the housing body 21 between one end in the width direction of the detection housing portion 29 and the other end in the width direction of the closing portion 27. . The window portion 34 constitutes a rear end opening of the slide accommodating portion 26. The rear end surface of the housing body 21 is an electric wire drawing surface 35 from which an electric wire (not shown) connected to the female terminal fitting is drawn.
The cover 22 is made of a synthetic resin and has a cap shape as a whole as shown in FIG. Then, the cover 22 is attached to the housing main body 21 from behind so as to cover the electric wire drawing surface 35. One end in the width direction of the cover 22 is opened as an electric wire outlet 36. Each electric wire drawn out from the housing body 21 is housed in the cover 22 in a bent state, and is led out from the electric wire outlet 36 to one side in the width direction. The cover 22 has a pair of side walls 37 along the width direction, and a substantially cylindrical support shaft 38 projects from the center of the outer surface of both side walls 37.

  The rotary lever 40 is made of synthetic resin and has a portal plate shape as a whole as shown in FIG. 9, and is substantially parallel to each other from the operation portion 41 along the height direction and both ends of the operation portion 41. It consists of a pair of projecting portions 42 that protrude. Both action portions 42 are formed with penetrating substantially circular bearing portions 43 that receive the support shaft 38. The rotary lever 40 is rotatable about the axis of the support shaft 38 between the initial position and the fitting position with respect to the housing 20 with the support shaft 38 fitted to the bearing portion 43.

  A plurality of pinion teeth 44 (corresponding to the interlocking portion of the present invention) are formed on the outer peripheral edge of the action portion 42. Each pinion tooth 44 has a radial shape centered on the support shaft 38 as a whole, and is repeatedly formed over a range of a semicircular arc or more on the outer peripheral edge of the action portion 42. Each pinion tooth 44 is defined between a plurality of recesses 45 formed in the action portion 42. Each recess 45 is opened on the outer surface and the outer peripheral edge of the action part 42, and is closed on the inner surface of the action part 42. In a state where the cover 22 is attached to the housing body 21, the front end portion of each pinion tooth 44 enters the inside of the slide accommodating portion 26 through the window portion 34.

  The sliding lever 60 is made of a synthetic resin and has a portal plate shape as a whole as shown in FIG. 8, and protrudes substantially parallel to each other from the connecting portion 61 along the height direction and both ends of the connecting portion 61. And a pair of arm portions 62. Both arm portions 62 are formed with cam grooves 63 that receive the opposite cam follower 104. The cam grooves 63 are arranged in a pair in the width direction substantially parallel to each other, extend in a downward gradient toward the other end in the width direction, and open at the front end of the arm portion 62. The sliding lever 60 is configured such that the housings 20 and 100 are fitted to the housing 20 at an initial position where the connecting portion 61 is spaced apart and a fitting position where the connecting portion 61 is placed close to the housing 20. It is possible to advance and retract linearly in the width direction substantially orthogonal to the direction. In the initial position, the housings 20 and 100 are shallowly fitted and the cam followers 104 enter the respective cam grooves 63. By relatively moving, the fitting of both the housings 20 and 100 proceeds, and at the fitting position, each cam follower 104 reaches the back end of each cam groove 63 so that both the housings 20 and 100 are properly fitted. ing.

  A plurality of rack teeth 64 (corresponding to an interlocking portion of the present invention) are formed on the rear end edge of the arm portion 62. Each rack tooth 64 has a sawtooth shape along the width direction as a whole, and has a length range approximately half of the protruding dimension of the arm portion 62 on the other end side (front end side) in the width direction at the rear end edge of the arm portion 62. It is repeatedly formed over the entire area. Each rack tooth 64 is defined between a plurality of valley portions 65 formed at the rear end edge of the arm portion 62. Each valley portion 65 is opened at the inner surface and the rear end edge of the arm portion 62, and is closed at the outer surface of the arm portion 62. In a state where the arm portion 62 is inserted into the slide accommodating portion 26, each rack tooth 64 faces the window portion 34, and each rack tooth 64 and each pinion tooth 44 mesh with each other through the window portion 34. . Then, by the engagement of each rack tooth 64 and each pinion tooth 44, the forward / backward movement of the slide lever 60 is interlocked with the rotation of the rotation lever 40.

  The detection member 80 is made of a synthetic resin and has a portal plate shape as a whole as shown in FIG. 10, and is substantially parallel to each other from both the detection operation unit 81 along the height direction and both ends of the detection operation unit 81. It comprises a pair of projecting detection main body portions 82. The detection operation part 81 and the detection main body part 82 are each in the shape of a square bar, and an intermediate part of the detection operation part 81 is thicker than the detection main body part 82. Moreover, the detection member 80 is made smaller than each of the sliding lever 60 and the rotating lever 40 as a whole.

  As shown in FIG. 11, a pair of recesses 83 are formed in the middle part of both detection main body parts 82 so as to open inward, and a pair of elastic pieces 84 are formed so as to protrude into the recesses 83. Has been. As shown in FIG. 12, the elastic piece 84 includes an elastic main body 85 extending from one end surface in the width direction of the recess 83 to the other side, and a protrusion protruding downward from the other width direction other end (tip portion) of the elastic main body 85. Part 86 and a locking part 87 projecting downward from a substantially middle part of the elastic main body 85, and can be bent and deformed in the front-rear direction with one end surface in the width direction of the concave part 83 serving as the root part of the elastic main body 85 as a fulcrum ing.

  The protrusion 86 is larger than the locking portion 87 and smaller than each of the pinion teeth 44 and the rack teeth 64. The front part of the one end surface in the width direction of the protrusion 86 is an inclined surface 88 that is inclined downward toward the other side, and the other end surface in the width direction of the protrusion 86 is a straight surface 89 along the front-rear direction. . The detection member 80 moves in a width direction substantially perpendicular to the fitting direction of the housings 20 and 100 and moves the sliding lever 60 between a standby position where the housing 20 is approached shallow and a detection position where the housing 20 is approached deeply. It can be displaced in the direction opposite to the direction. The detection member 80 is detected by the engagement of the engagement portion 87 with the temporary engagement reception portion 32, thereby holding the movement restricted state at the standby position, and the engagement of the engagement portion 87 with the main engagement reception portion 33. The position is held in the movement restricted state. The protrusion 86 is always in a state of entering the communication part 30.

  By the way, when the detection member 80 is in the detection position and the slide lever 60 is in the fitting position, the protrusions 86 of the detection main body portions 82 engage the rack teeth 64, and the slide lever 60 is in the initial position. Return displacement to the position is regulated. Further, at this time, the both arm portions 62 are disposed so as to be able to contact the closing wall 39 (see FIG. 6) on the other end in the width direction of the slide accommodating portion 26, so that the sliding lever 60 is positioned more than the fitting position. Displacement to the other side is also regulated. That is, the protrusion 86 locks the rack teeth 64, so that the advancement / retraction of the slide lever 60 is restricted, and thus the elastic piece 84 constitutes the advance / retreat restriction part of the present invention.

  Further, when the detection member 80 is in the detection position and the rotary lever 40 is in the fitting position, the head 90 (see FIG. 13) at one end (tip) in the width direction of both detection main body portions 82 is a pinion. The teeth 44 are locked to restrict the return displacement of the rotary lever 40 to the initial position and the displacement forward of the fitting position. That is, the heads 90 of the two detection main body portions 82 are engaged with the pinion teeth 44 so that the rotation of the rotary lever 40 is restricted. The part 90 constitutes a rotation restricting part.

Next, a method for fitting the connector 10 according to this embodiment will be described.
Prior to the fitting of the two housings 20 and 100, as shown in FIGS. 1 and 3, the operating portion 41 is pulled toward the other end in the width direction, and the rotary lever 40 is retained at the initial position, and the slide accommodating portion. 26, the arm portion 62 is shallowly inserted from one end in the width direction, the sliding lever 60 is held at the initial position, and the detection main body portion 82 is inserted shallowly from the other end in the width direction into the detection accommodating portion 29. The member 80 is retained at the standby position. At this time, the portions on the other end side in the width direction of the pinion teeth 44 and the rack teeth 64 mesh with each other. Specifically, the pinion teeth 44 on the other side in the width direction are fitted in the valleys 65, and the rack teeth 64 on the other side in the width direction are fitted in the recess 45.

  Subsequently, the housings 20 and 100 are shallowly fitted, and the cam follower 104 is inserted into the entrance of the cam groove 63. In this state, the rotary lever 40 is fitted to the other side in the width direction (fitting). Rotate toward (position). Then, as shown in FIG. 4, the slide-type lever 60 advances toward the fitting position in conjunction with the rotary lever 40 by the rack and pinion mechanism. Further, when the sliding lever 60 moves, the cam follower 104 is relatively displaced toward the back end side of the cam groove 63, and a cam action is exerted between the mating housing 100 and the sliding lever 60. Is attracted to the housing 20 with a low fitting force.

  Thus, when the rotary lever 40 and the slide lever 60 reach the fitting position, as shown in FIGS. 3 and 5, the operation portion 41 reaches one end in the width direction and is supported on the rear end surface of the cover 22. The distal end of the arm portion 62 is disposed so as to be able to contact the closing wall 39 of the slide accommodating portion 26, and the arm portion 62 is fitted to substantially the entire inside of the slide accommodating portion 26. Further, at the fitting position, the pinion teeth 44 on one end side in the width direction are fitted into the valley portion 65, and the rack teeth 64 on one end side in the width direction are fitted in the recess 45. Then, when the sliding lever 60 reaches the fitting position, both the housings 20 and 100 are properly fitted, and both male and female terminal fittings are conductively connected at a normal depth.

  When the sliding lever 60 reaches the fitting position, the rack tooth 64 on the other end in the width direction comes into contact with the protrusion 86, and the elastic piece 84 is bent and deformed. It rides on the side rack teeth 64. As a result, the locking portion 87 is separated from the temporary locking receiving portion 32 and the locked state of both is released, and the movement of the detection member 80 to the detection position is allowed. At this time, the head 90 of the detection main body 82 and the recess 45 in the intermediate portion of the rotary lever 40 are opposed to each other in the width direction with a predetermined gap.

  In the above state, the detection operation unit 81 is pushed toward the other end in the width direction to bring the detection member 80 to the detection position. Then, as shown in FIG. 6, the protruding portion 86 gets over the rack tooth 64 on the other end in the width direction, and the elastic piece 84 is elastically restored, so that the protruding portion 86 becomes the valley portion 65 on the other end in the width direction. Fit into. Thus, the protrusion 86 locks the rack teeth 64 from one end in the width direction, whereby the sliding lever 60 is held in the movement restricted state at the fitting position. Further, with the return of the elastic piece 84, the locking portion 87 is fitted into the main locking receiving portion 33, whereby the detection member 80 is held in the movement restricted state at the detection position.

  Further, when the detection member 80 reaches the detection position, the head 90 of the detection main body 82 enters the recess 45 of the rotary lever 40 from the other end in the width direction. Thus, when the head 90 is engaged with the pinion teeth 44, the turning operation of the turning lever 40 is restricted, and the turning lever 40 is held in the movement restricted state at the fitting position. The sliding lever 60 and the pivoting lever 40 are thus locked to the detection member 80, and the detection member 80 is locked to the housing 20, so that the two housings 20, 100 are properly fitted. Kept in a state.

  On the other hand, when the sliding lever 60 has not reached the fitting position, the protrusion 86 is not ridden on the rack tooth 64, and the locking state between the locking portion 87 and the temporary locking receiving portion 32 is the same. The displacement of the detection member 80 to the detection position is restricted. Further, if the sliding lever 60 has reached the fitting position, but the rotating lever 40 has not reached the fitting position, the detection member 80 can be pushed into the detection position. However, the head 90 does not bite into the pinion teeth 44, and the detection member 80 does not reach the detection position. Therefore, it is possible to detect whether or not both housings 20 and 100 have reached the normal fitting state based on whether or not the detection member 80 can be moved to the detection position.

  By the way, depending on the installation situation of the connector 10 and the like, it may be difficult to operate the rotary lever 40. In that case, it is possible to remove the cover 22 and the rotary lever 40 from the housing 20 and operate only with the slide lever 60. That is, as shown in FIGS. 14 to 17, the sliding lever 60 is pressed in the state where the sliding lever 60 is held at the initial position and the housings 20 and 100 are shallowly fitted, and the sliding lever 60 is pressed. Is pushed into the mating position. Then, similarly to the above, the fitting of the two housings 20 and 100 proceeds by the cam action of the cam groove 63 and the cam follower 104, and the two housings 20 and 100 are properly fitted by reaching the fitting position. Further, when the sliding lever 60 reaches the fitting position, the rack teeth 64 release the locked state of the elastic piece 84, and the displacement of the detection member 80 to the detection position is allowed. Thus, when the detection member 80 is pushed into the detection position, as shown in FIG. 18, the protrusion 86 engages the rack teeth 64, and the sliding lever 60 is held in the movement restricted state at the fitting position.

  As described above, according to the present embodiment, the detection member 80 is pushed into the detection position after the rotary lever 40 and the slide lever 60 reach the fitting position, so that the head of the detection main body portion 82 is pressed. The portion 90 locks the rotary lever 40 to restrict the rotation of the rotary lever 40, and the protrusion 86 of the elastic piece 84 locks the slide lever 60 to move the slide lever 60 forward and backward. In order to regulate, it is possible to know that both the sliding lever 60 and the rotating lever 40 have reached the fitting position when the detection member 80 reaches the detection position.

  At the detection position, the head 90 of the detection main body 82 locks the pinion teeth 44, and the protrusion 86 of the elastic piece 84 only locks the rack teeth 64. The locking structure of the rotary lever 40 and the slide lever 60 is provided with a relatively simple shape such as 86, and the configuration of the detection member 80 is simplified.

  Even if the rotary lever 40 is omitted, the fitting of the housings 20 and 100 proceeds only by the slide lever 60, and the protrusion 86 of the detection member 80 reaching the detection position causes the slide lever 60 to move. In order to restrict the advance and retreat of the slide lever 60 by locking, it is possible to remove the rotary lever 40 according to the installation status of the connector 10 and use the slide lever 60 alone.

  In addition, the detection member 80 is held at the standby position by the locking portion 87 locking the temporary locking receiving portion 32, and the slide lever is locked by the projection 86 locking the rack teeth 64 at the detection position. Since 60 is retained at the fitting position and both the locking portion 87 and the protrusion 86 are formed on the elastic piece 84, the configuration of the detection member 80 is further simplified.

  Further, since the rotation of the rotary lever 40 is restricted by the head 90 of the detection main body 82, the structure of the rotation restricting part is not particularly complicated, and the structure of the detection member 80 is further simplified. The
