[Description of embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.
The lever type connector of the present disclosure includes:
(1) Includes a pair of sliders, a wire cover, and a lever. The pair of sliders have a housing that can be fitted with the mating housing, a cam groove for sliding the cam follower of the mating housing, and a pair of racks, and are provided to be movable linearly with respect to the housing. The wire cover can be attached to the housing so as to cover the wire drawing-out surface of the housing, and in the opposite direction in the moving direction of the slider. The lever is rotatably attached to the wire cover and has a pair of gears. In this lever type connector, by rotating the lever with a pair of gears individually engaged with a pair of racks, the rotational force of the lever is transmitted to the slider, and the mating housing and the housing are mated and uncoupled. It is now possible to do so. The pair of gears are asymmetrically formed, and the pair of racks are asymmetrically formed. According to this configuration, the pair of gears are formed asymmetrically and the pair of racks are formed asymmetrically, so even if you try to assemble the wire cover to which the lever is attached to the housing in the opposite direction from the specified direction, , the gear and rack will no longer mesh. Therefore, it is possible to prevent the lever and the slider from engaging in an inappropriate orientation.

(2) The pair of gears and the pair of racks have the same pitch. The pair of gears are arranged so as to be offset from each other in the circumferential direction around the spindle, and when the pair of sliders are placed at a predetermined initial position with respect to the housing, the pair of racks are arranged so as to be offset from each other in the direction of slider movement. It is preferable that they be arranged as follows. According to this configuration, since the pair of gears and the pair of racks have the same pitch, it is easier to design them than when designing them with different pitches.

(3) Preferably, the pair of sliders are housed inside the housing. According to this configuration, since the slider does not protrude from the housing, the outer shape of the connector can be easily suppressed.

(4) It is preferable that the mating housing is fixed to the circuit board, and that the pair of sliders can be assembled to the housing by being reversed in the moving direction of the sliders. According to this configuration, the orientation of the housing with respect to the circuit board is determined by the orientation of the mating housing fixed to the circuit board. The direction of movement of the slider in the housing during engagement and disengagement determines the direction of rotation of the lever during engagement and disengagement. Once the direction of rotation of the lever is determined, the direction in which the wires are led out (the direction in which the wire cover is assembled to the housing) is determined. In this lever type connector, the slider can be assembled with the slider reversed in the direction of movement of the slider, so even if the orientation of the housing is determined, the direction in which the electric wires are led out can be set arbitrarily.

[Embodiment 1]
Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 13. The lever type connector 10 includes a housing 20, a wire cover 22, a lever 40, and a pair of sliders 60.

Both ends of the slider accommodating portions 26 in the front and rear directions are open and are formed to penetrate in the front and rear direction. The slider accommodating portion 26 can accommodate a slider 60 therein through openings at both ends in the left and right direction (see FIG. 1).

A window portion 34 is formed at the upper end of the central portion of each slider accommodating portion 26 in the front-rear direction and is long and open in the front-rear direction. The window portion 34 communicates the interior space of the slider accommodating portion 26 with the outside. The upper end surface of the housing 20 is a wire drawing surface 35. The electric wire connected to the female terminal fitting is drawn out from the housing 20 via the wire drawing surface 35.

A pair of grooves 24A are formed at both ends of the upper edge of each long side surface portion 24 in the front-rear direction, recessed inward in the left-right direction. A pair of protrusions 25A that protrude outward in the front-rear direction are provided at both ends in the left-right direction of the upper end edge of each short side surface portion 25.

The wire cover 22 is made of synthetic resin. The wire cover 22 is attached to the upper end of the housing 20 and has a function of covering the wire drawing surface 35 of the housing 20 (see FIG. 5). As shown in FIGS. 3 and 4, the wire cover 22 includes a first wall portion 22A and a second wall portion 22B facing each other, and a connecting wall portion 22C that connects the first wall portion 22A and the second wall portion 22B. It is equipped with The first wall portion 22A is arranged so as to stand upward with the plate thickness direction facing in the left-right direction. The second wall portion 22B is arranged so as to stand upward with the plate thickness direction facing the front-rear direction, and is arranged so as to be continuous with the front end portion of each first wall portion 22A (see FIG. 4). The connecting wall portion 22C is arranged so as to be continuous with the upper ends of the pair of first wall portions 22A and second wall portions 22B. A wire outlet 22D is formed at the rear end of the wire cover 22 and opens from the lower end to the upper end. The ends of each electric wire drawn upward from the upper end of the housing 20 are accommodated inside the electric wire cover 22 in a bent state, and are led out from the electric wire outlet 22D. A cylindrical support shaft 38 is provided at the lower end of the center portion in the front-rear direction on the outer surface of the pair of first wall portions 22A so as to protrude outward in the left-right direction.

One claw portion 37A that protrudes inward in the left-right direction is provided at each of the inner lower end portions in the left-right direction of the pair of first wall portions 22A on the side where the wire outlet 22D opens. A pair of locking holes 38A are formed at both ends of the second wall portion 22B in the left-right direction so as to penetrate in the front-back direction (see FIG. 4).

The wire cover 22 can be attached to the housing 20 by being reversed in the front-back direction. For example, as shown in FIG. 5, the second wall portion 22B of the wire cover 22 is arranged to cover the upper end portion of the front short side surface portion 25 from the front, and the locking hole 38A of the second wall portion 22B is Insert the protrusion 25A of the short side surface portion 25 on the front side. Then, the claw portion 37A of the first wall portion 22A of the wire cover 22 is engaged with the groove 24A located on the rear short side surface portion 25 side. In this way, the wire cover 22 can be attached to the housing 20 with the wire outlet 22D disposed on the rear short side surface portion 25 side.

Further, the second wall portion 22B of the wire cover 22 is arranged so as to cover the rear short side portion 25 from the rear, and the rear short side portion 25 is inserted into the locking hole 38A of the second wall portion 22B. Insert the protrusion 25A. Then, the claw portion 37A of the first wall portion 22A of the wire cover 22 is engaged with the groove 24A located on the front short side surface portion 25 side. In this way, the wire cover 22 can be attached to the housing 20 with the wire outlet 22D disposed on the front short side surface portion 25 side.

The lever 40 is made of synthetic resin. As shown in FIG. 6, the lever 40 has a gate-like plate shape as a whole, and has an operating portion 41 extending in the left-right direction, and a flat plate-shaped parallel to each other, facing rearward from each of the left and right ends of the operating portion 41. It has a pair of action parts 42 extending to . A bearing hole 43 for receiving the support shaft 38 is formed at the rear end of each operating portion 42 so as to penetrate in the plate thickness direction (horizontal direction).

As shown in FIG. 7, a gear 44 is formed on each outer peripheral edge of the rear end portion of each action portion 42. As shown in FIG. That is, the lever 40 has a pair of gears 44. These gears 44 have the same pitch. Each gear 44 is formed around the bearing hole 43. A recess 45 is formed in the gear 44 . Each recess 45 is opened toward the inside of the action portion 42 in the left-right direction and toward the outside of the outer peripheral edge. When the wire cover 22 is attached to the housing 20, the tip of each gear 44 (the portion radially away from the bearing hole 43) enters into the slider housing portion 26 through the window portion 34. (See Figure 1).

Each gear 44 provided in each of the pair of action parts 42 is asymmetrically formed. Specifically, the gear 44 in one of the action parts 42 and the gear 44 in the other action part 42 are arranged offset from each other around the bearing hole 43. In other words, the gears 44 provided in each of the pair of action parts 42 are arranged so as to be out of phase with each other.

The lever 40 formed in this manner is rotatably attached to the wire cover 22 by fitting the support shaft 38 into the bearing hole 43 (see FIG. 1). Specifically, the gears 44 of the pair of acting parts 42 are oriented downward, the pair of acting parts 42 are oriented to extend forward and upward from the support shaft 38, and the operating part 41 is arranged above the second wall part 22B. In this position, the lever 40 is attached to the wire cover 22 (see FIG. 1). In this state, the pair of gears 44 are arranged so as to be offset from each other in the circumferential direction of the support shaft 38. When the lever 40 is in this attitude with respect to the wire cover 22, the lever 40 is in the initial position (see FIG. 1).

The pair of sliders 60 are made of synthetic resin and have a flat plate shape extending in one direction. As shown in FIG. 8, each of the pair of sliders 60 is formed with a cam groove 63 that receives and slides the cam follower 104 of the mating housing 100. The cam groove 63 is inclined upward in the forward direction and opens at the lower end. A rack 64 is formed at the upper edge of each slider 60. That is, the pair of sliders 60 have a pair of racks 64. Each rack 64 has the same pitch, has a serrated shape along the front-rear direction, and is formed at the center of the upper edge of the slider 60 in the front-rear direction. The pitch of each rack 64 is the same as the pitch of the gear 44 of the lever 40. A trough 65 is formed in the rack 64. Each trough portion 65 is open to the outside and upper side of the slider 60 in the left-right direction.

As shown in FIG. 9, the racks 64 provided on each of the pair of sliders 60 (that is, the pair of racks 64) are asymmetrically formed. Specifically, the plurality of racks 64 in one slider 60 and the plurality of racks 64 in the other slider 60 are arranged to be shifted from each other in the front-rear direction. In other words, the phases of the racks 64 provided on each of the pair of sliders 60 are shifted in the front-rear direction. Each of the pair of sliders 60 is provided with a locking convex portion 66 that projects outward in the left-right direction.

The pair of sliders 60 can be assembled by being reversed in the moving direction of the sliders 60 with respect to the slider accommodating portion 26 of the housing 20 (inside the housing 20). For example, as shown in FIG. 10, one slider 60 is accommodated in the slider accommodating section 26 on the left side, and the other slider 60 is accommodated in the slider accommodating section 26 on the right side. At this time, the attitude of each slider 60 is such that the rack 64 faces upward and the rack 64 faces outward in the left-right direction. Then, the locking convex portion 66 of each slider 60 is fitted into the first locking recess 26A formed so as to face the rear side of the slider accommodating portion 26. Then, each slider 60 is accommodated in the slider accommodating portion 26 of the housing 20 so as to be flush with the outer surface of the short side surface portion 25 on the rear side. Each slider 60 is held at the initial position in each slider accommodating portion 26 by fitting each locking convex portion 66 into each first locking recess 26A. In this way, when the pair of sliders 60 are arranged at the predetermined initial position with respect to the housing 20, the pair of racks 64 are arranged so as to be out of phase with each other in the front-rear direction (the direction of movement of the slider 60). .

Further, the other slider 60 is accommodated in the slider accommodating section 26 on the left side, and the one slider 60 is accommodated in the slider accommodating section 26 on the right side. In this case, the locking convex portion 66 of each slider 60 fits into the second locking recess 26B formed so as to face the front side of the slider accommodating portion 26. As a result, each slider 60 is accommodated in the slider accommodating portion 26 of the housing 20 so as to be flush with the outer surface of the short side surface portion 25 on the front side. The slider 60 accommodated in the slider accommodating portion 26 in this manner is capable of linear movement in the front-rear direction with respect to the housing 20. That is, the pair of sliders 60 are provided so as to be linearly movable with respect to the housing 20.

[An example of the process of attaching the wire cover to the housing]
Next, an example of the process of attaching the wire cover 22 to the housing 20 in a set orientation will be described. First, the lever 40 is attached to the wire cover 22. Specifically, the posture of the lever 40 with respect to the wire cover 22 is such that the gears 44 of the pair of acting parts 42 face downward, the pair of acting parts 42 extend forward and upward from the support shaft 38, and the operating part 41 is arranged above the second wall portion 22B. Then, the bearing hole 43 is fitted into the support shaft 38 (see FIG. 1). At this time, the lever 40 is in an initial position relative to the wire cover 22.

Next, the pair of sliders 60 are accommodated in the slider accommodating portion 26 of the housing 20. Specifically, one slider 60 is accommodated in the slider accommodating section 26 on the left side, and the other slider 60 is accommodated in the slider accommodating section 26 on the right side. At this time, the posture of each slider 60 is such that the rack 64 is at the upper end, and the rack 64 is oriented outward in the left-right direction. Then, the locking protrusion 66 of each slider 60 is fitted into the first locking recess 26A on the rear side (see FIG. 10). In this way, each slider 60 is accommodated in the slider accommodating portion 26 while being held at the initial position.

Next, the wire cover 22 is attached to the housing 20. First, the support shaft 38 of the electric wire cover 22 is oriented to be located at the lower end, the second wall portion 22B is placed on the front side, and the electric wire outlet 22D is placed on the rear side. Then, the wire cover 22 is approached from above the housing 20. Then, as shown in FIG. 11, the gear 44 of the left action section 42 of the lever 40 engages with the rack 64 of one slider 60, and the gear 44 of the right action section 42 of the lever 40 engages the rack 64 of the other slider 60. mesh with each other. In this way, the pair of gears 44 are individually engaged with the pair of racks 64. At the same time, the protrusion 25A of the front short side surface 25 is inserted into the locking hole 38A of the second wall 22B, and the claw 37A of the first wall 22A of the wire cover 22 is inserted into the locking hole 38A of the second wall 22B. It is locked in the groove 24A located at (see FIG. 5). In this way, the wire cover 22 is attached to the housing 20 with the wire outlet 22D disposed on the rear side.

Here, with one slider 60 accommodated in the left slider accommodating section 26 and the other slider 60 accommodated in the right slider accommodating section 26, the second wall section 22B is arranged on the rear side, and the electric wire outlet The wire cover 22 is approached from above the housing 20 with the wire cover 22D placed on the front side. In this case, as shown in FIG. 12, the gear 44 and the rack 64 collide and do not mesh with each other. In this way, when one slider 60 is accommodated in the left slider accommodating part 26 and the other slider 60 is accommodated in the right slider accommodating part 26, the electric wire cover 22 has the electric wire outlet 22D arranged on the rear side. It is permitted to assemble the electric wire outlet 22D to the housing 20, and it is prohibited to assemble the electric wire outlet 22D by arranging it on the front side.

Also, one slider 60 is accommodated in the slider accommodating portion 26 on the right side, the other slider 60 is accommodated in the slider accommodating portion 26 on the left side, and the locking convex portion 66 of each slider 60 is inserted into the second locking recess on the front side. 26B. In this case, the wire cover 22 is allowed to be assembled to the housing 20 with the wire outlet 22D disposed on the front side, and is prevented from being assembled with the wire outlet 22D disposed on the rear side. That is, by changing the combination in which each slider 60 is inserted into each slider accommodating portion 26, the electric wire cover 22 can be assembled in the reverse direction in the front-back direction (the moving direction of the slider 60).

[An example of the process of fitting the housing and the mating housing]
Next, the housing 20 to which the wire cover 22 is attached is fitted into the mating housing 100. With the lever 40 at the initial position, the housing 20 and the mating housing 100 are shallowly fitted. Then, each cam follower 104 enters into each cam groove 63 of the slider 60 from below. Then, the operating portion 41 of the lever 40 is rotated around the support shaft 38 in a direction to bring it closer to the wire outlet 22D. Then, the rotational force applied to the lever 40 is transmitted to the slider 60 via the gear 44 and the rack 64, and the slider 60 linearly moves forward within the slider accommodating portion 26. As a result, each cam follower 104 moves relatively along each cam groove 63, and the fitting between the housing 20 and the mating housing 100 progresses.

Then, the operating portion 41 of the lever 40 reaches a position close to the wire outlet 22D (see FIG. 13). At this time, each cam follower 104 reaches the inner end of each cam groove 63, and the housing 20 and the mating housing 100 are properly fitted, and both male and female terminal fittings are connected at a regular depth. A state in which the operating portion 41 of the lever 40 is close to the wire outlet 22D is a mating completion position.

Further, in a state where the housing 20 and the mating housing 100 are properly fitted, the operating portion 41 of the lever 40 is rotated around the support shaft 38 in a direction to bring it closer to the second wall portion 22B. Then, the rotational force applied to the lever 40 is transmitted to the slider 60 via the gear 44 and the rack 64, and the slider 60 moves rearward within the slider accommodating portion 26. As a result, each cam follower 104 moves relatively along each cam groove 63, and separation of the housing 20 and the mating housing 100 progresses.

Next, the operation of the first embodiment will be explained.

The lever type connector 10 includes a pair of sliders 60, a wire cover 22, and a lever 40. The pair of sliders 60 have a housing 20 that can be fitted with the mating housing 100, a cam groove 63 for sliding the cam follower 104 of the mating housing 100, and a pair of racks 64, and are linear with respect to the housing 20. Provided to allow movement. The wire cover 22 can be attached to the housing 20 so as to cover the wire drawing surface 35 of the housing 20 and in an opposite direction in the moving direction of the slider 60. The lever 40 is rotatably attached to the wire cover 22 and has a pair of gears 44 . In the lever type connector 10, by rotating the lever 40 with a pair of gears 44 individually engaged with a pair of racks 64, the rotational force of the lever 40 is transmitted to the slider 60, and the mating housing 100 and the housing 20 are rotated. and can be fitted and separated. The pair of gears 44 are asymmetrically formed, and the pair of racks 64 are asymmetrically formed. According to this configuration, since the pair of gears 44 are formed asymmetrically and the pair of racks 64 are formed asymmetrically, the wire cover 22 to which the lever 40 is attached can be reversed from the specified direction and attached to the housing 20. Even if an attempt is made to assemble the gear 44 and the rack 64 will not mesh with each other. Therefore, it is possible to prevent the lever 40 and the slider 60 from engaging in an inappropriate orientation.

The pair of gears 44 and the pair of racks 64 have the same pitch. The pair of gears 44 are arranged to be offset from each other in the circumferential direction around the support shaft 38, and when the pair of sliders 60 are arranged at a predetermined initial position with respect to the housing 20, the pair of racks 64 are arranged so as to be offset from each other in the circumferential direction around the support shaft 38. 60 in the direction of movement. According to this configuration, the pair of gears 44 and the pair of racks 64 have the same pitch, so it is easier to design them than if they were designed with different pitches.

A pair of sliders 60 are housed inside the housing 20. According to this configuration, since the slider 60 does not protrude from the housing 20, the external shape of the lever type connector 10 can be easily suppressed.

The mating housing 100 is fixed to a circuit board, and the pair of sliders 60 can be assembled to the housing 20 by being reversed in the moving direction of the sliders 60. According to this configuration, the orientation of the housing 20 with respect to the circuit board is determined by the orientation of the mating housing 100 fixed to the circuit board. The direction of movement of the slider 60 in the housing 20 when it is fitted and removed determines the direction of rotation of the lever 40 when it is fitted and removed. When the rotation direction of the lever 40 is determined, the direction in which the electric wire is led out (the direction in which the electric wire cover 22 is assembled to the housing 20) is determined. Since this lever-type connector 10 can be assembled with the slider 60 reversed in the moving direction of the slider 60, even if the orientation of the housing 20 is determined, the direction in which the electric wires are led out can be arbitrarily set.
