[Explanation of Embodiments of the present disclosure]
First, embodiments of the present disclosure will be listed and described.

(1) The connector of the present disclosure includes a male housing having a hood portion that opens forward, a terminal fitting that is housed inside the male housing and has a tab protruding inside the hood portion, and the hood portion. A female housing fitted inside the hood, and a moving plate that positions the tab inside the hood and is movable in the front-rear direction between the initial position and the fitting position behind the initial position. The female housing has a female claw that engages with a plate protrusion provided on the moving plate while being fitted inside the hood portion, and the male housing has a female housing. The female housing, which has a reverse tapered surface and has a hooking claw that holds the moving plate in the initial position by being locked to the plate protrusion, and the female housing fitted inside the hood portion is the hood. When detaching forward from the inside of the portion, the hooking claw engages with the plate protrusion and bends the plate protrusion to release the lock between the female claw and the plate protrusion, and the female housing. It is a connector that allows the moving plate to move forward from the initial position while allowing the moving plate to move forward.

According to such a configuration, since the hooking claw that locks with the plate protrusion has an inverted tapered surface, the locking force that locks the moving plate so as not to be disengaged at the initial position is unlikely to decrease. Further, since the hooking claw bends the plate protrusion, it becomes easy to release the lock between the female claw and the plate protrusion, and it is possible to prevent the moving plate from being separated from the male housing together with the female housing.

(2) The male housing has a plate lock portion that holds the moving plate in the initial position by being locked to the plate protrusion, and the female housing fitted inside the hood portion is said. When the moving plate moves forward from the inside of the hood portion to the initial position, the plate lock portion engages with the plate protrusion to cause the female claw. It is preferable to make it difficult to disengage the lock between the plate and the plate protrusion.

According to such a configuration, in the process of moving the moving plate from the fitting position to the initial position, it becomes difficult to release the lock between the female claw and the plate protrusion, and the moving plate is initially set as the female housing moves. It becomes easy to move to the position.

(3) It is preferable that the female claw protrudes to the outer surface of the female housing, and the protruding end of the female claw is a fillet portion having a rounded shape.

According to such a configuration, in the process of moving the moving plate from the fitting position to the initial position, the plate protrusion can easily get over the female nail, and the moving plate can be prevented from being separated from the male housing together with the female housing.

That is, the female housing 40 moves to the back of the hood portion 11. As shown in FIG. 7, the female engaging portion 44b of the female claw 44 engages with the plate protrusion 36, and when the female housing 40 advances further to the depth of the hood portion 11, as shown in FIG. 6, the female housing 40 The front end abuts on the plate body 31, and the plate protrusion 36 gets over the female claw 44. Here, the female locking portion 44c is in a state of being locked with the rear locking portion 36a. When the female housing 40 further moves, the female engaging portion 44b engages with the plate lock portion 24, and the male locking portion 24a of the plate lock portion 24 gets over the plate protrusion 36. Then, as shown in FIG. 5, the outer locking portion 36b of the plate protrusion 36 engages with the male engaging portion 24b, and when the female housing 40 further moves, the plate main body portion 31 becomes the main body as shown in FIG. It comes into contact with the front end of the portion 12, and the fitting of the connector 1 is completed. At the fitting position, the rear locking portion 36a locks the female locking portion 44c and the outer locking portion 36b locks the male engaging portion 24b, respectively. As shown in FIG. 10, in a state where the fitting of the connector 1 is completed, the lever lock portion 55 is engaged with the lever lock receiving portion 21 and the locking projection receiving portion 56 is engaged with the locking projection 20b, respectively. The combined state is maintained.

[Separation of male housing and female housing]
When the male housing 10 and the female housing 40 in the fitted state are separated from each other, the female housing 40 is relative to the male housing 10 as the lever 50 is rotated, contrary to the above fitting. By pulling it apart, the detachment operation is assisted. That is, the female housing 40 moves from the position shown in FIG. 4 to the position shown in FIG. As shown in FIG. 5, the outer locking portion 36b of the plate protrusion 36 engages with the male engaging portion 24b to maintain a state in which the rear locking portion 36a and the female locking portion 44c are not easily disengaged. While still, the female housing 40 moves to the left in the drawing. When the moving plate 30 reaches the vicinity of the initial position (the position of the moving plate 30 shown in FIG. 6), the outer locking portion 36b and the male engaging portion 24b are disengaged, and as shown in FIG. The stop portion 36c rides on the reverse tapered surface 23b of the hooking claw 22, and the plate protrusion 36 bends in the direction approaching the side wall 17. Further, the rear locking portion 36a and the female locking portion 44c are disengaged, and the plate protrusion 36 begins to get over the fillet portion 44a. As shown in FIG. 7, with the front locking portion 36c engaged with the reverse tapered surface 23b, the female claw 44 is allowed to disengage in the left direction in the drawing while engaging with the plate protrusion 36. When the female claw 44 and the plate protrusion 36 are disengaged, the moving plate 30 reaches the initial position as shown in FIG.

[Design of suitable inclined surfaces of each member]
In order to properly fit and detach the connector 1 as described above, the inclined surface of each member may be designed as follows. As shown in FIG. 11, the inclination angle of the inclined surface of each member is defined. θ1 is the angle formed by the rear locking portion 36a and the virtual surface P1 extending in the fitting direction. θ2 is the angle formed by the female locking portion 44c and the surface 45 extending in the fitting direction in the female housing 40. θ3 is the angle formed by the reverse tapered surface 23b and the surface 25 extending in the fitting direction on the hooking claw 22. θ4 is the angle formed by the front locking portion 36c and the virtual surface P1. θ5 is the angle formed by the male engaging portion 24b and the virtual surface P2 extending in the fitting direction. θ6 is an angle formed by the outer locking portion 36b and the virtual surface P3 extending in the fitting direction.

In relation to θ1 and θ2, it is preferable to satisfy the following equation (1).
θ1 <θ2 <90 ° (1)
By designing in this way, the locking between the rear locking portion 36a and the female locking portion 44c can be easily disengaged, and when the connector 1 is disengaged, the moving plate 30 does not disengage together with the female housing 40, and the male housing is not disengaged. It becomes easy to be held inside the 10.

In relation to θ3 and θ4, it is preferable to satisfy the following equation (2).
θ4 <θ3 <90 ° (2)
With this design, when the front locking portion 36c engages with the reverse tapered surface 23b in the process of disconnecting the connector 1, the plate protrusion 36 tends to bend, and the rear locking portion 36a and the female locking portion 36a and the female locking portion. The lock with 44c is easily released.

In relation to θ5 and θ6, it is preferable to satisfy the following equation (3).
θ6 <θ5 <90 ° (3)
By designing in this way, the male engaging portion 24b and the outer locking portion 36b are easily engaged with each other, and the moving plate 30 is connected to the rear locking portion 36a from the fitting position to the vicinity of the initial position. The lock with the female locking portion 44c is less likely to come off.

To summarize the above, θ1, θ2, θ3, θ4, θ5, and θ6 are all acute angles, and the inclined surface of each member is designed so as to satisfy the magnitude relationship of equations (1), (2), and (3). Is preferable.

[Action and effect of this embodiment]
According to this embodiment, the following actions and effects are exhibited.

The connector 1 according to the present embodiment includes a male housing 10 having a hood portion 11 that opens forward, and a male terminal 14 that is housed inside the male housing 10 and has a tab 14a protruding inside the hood portion 11. The female housing 40 fitted inside the hood portion 11 and the tab 14a are positioned inside the hood portion 11 so that the tab 14a can be moved in the front-rear direction between the initial position and the fitting position behind the initial position. The female housing 40 is a connector 1 provided with a moving plate 30, and the female housing 40 is a female claw 44 that locks to a plate protrusion 36 provided on the moving plate 30 in a state of being fitted inside the hood portion 11. The male housing 10 has an inverted tapered surface 23b, has a hooking claw 22 that holds the moving plate 30 in the initial position by being locked to the plate protrusion 36, and is fitted inside the hood portion 11. When the combined female housing 40 is detached forward from the inside of the hood portion 11, the hooking claw 22 engages with the plate protrusion 36 and bends the plate protrusion 36 to bring the female claw 44 and the plate protrusion 36 together. It is a connector 1 that releases the lock, allows the female housing 40 to be detached, and restricts the moving plate 30 from moving forward from the initial position.

According to the above configuration, since the hooking claw 22 that locks with the plate protrusion 36 has the reverse tapered surface 23b, the locking force that locks the moving plate 30 so as not to disengage at the initial position is unlikely to decrease. .. Further, since the hook claw 22 bends the plate protrusion 36, it becomes easy to release the lock between the female claw 44 and the plate protrusion 36, and the moving plate 30 can be prevented from being separated from the male housing 10 together with the female housing 40. ..

In the present embodiment, the male housing 10 has a plate lock portion 24 that holds the moving plate 30 in the initial position by being locked to the plate protrusion 36, and the female housing 40 fitted inside the hood portion 11. When the moving plate 30 separates from the inside of the hood portion 11 forward, the plate lock portion 24 engages with the plate protrusion 36 in the process of moving the moving plate 30 from the fitting position to the initial position, so that the female claw 44 And the plate protrusion 36 are hard to be disengaged.

According to the above configuration, in the process of moving the moving plate 30 from the fitting position to the initial position, it becomes difficult to release the lock between the female claw 44 and the plate protrusion 36, and as the female housing 40 moves, it becomes difficult to release the lock. It becomes easy to move the moving plate 30 to the initial position.

In the present embodiment, the female claw 44 projects to the outer surface of the female housing 40, and the protruding end of the female claw 44 is a fillet portion 44a having a rounded shape.

According to the above configuration, in the process of moving the moving plate 30 from the fitting position to the initial position, the plate protrusion 36 easily gets over the female claw 44, and the moving plate 30 separates from the male housing 10 together with the female housing 40. Can be suppressed.
