Rotary shafts 13a formed on the support wall 13
Is engaged with the guide grooves 41 on the side wall from the inside of the cover 40, so that the cover 40 is slidable back and forth with respect to the housing 10.

The lower surface of the cover 40 is formed to be shorter in the front than the upper surface, so that when it is mounted on the tip of the housing 10, it slightly covers the front end of the lower surface of the housing 10. . On the contrary,
On the upper surface side, a pushing end 42 having a width slightly shorter than the width of the housing 10 is projected rearward at a portion behind the guide grooves 41, 41, and the pushing end 42 on the upper surface of the housing 10. A wide window portion 14 communicating with the cavities 11, 11, 11 is formed at a position facing.

Since the window portion 14 is formed on the rear side of the guide grooves 41, 41 and faces the push-in end 42, the cover 40 is located at the front end position in the slidable range so that the push-in end 42 is in the window portion 14. It is rotatable so as to enter and move upward at the tip. The window portion 14 is formed at a position where the rear end corner 21a of the upper surface of the terminal portion 21 is exposed to the outside in a process of inserting the terminal fitting 20 into the cavity 11 slightly to the proper insertion position. The pushing end 42 is in a position where the pushing end 42 can come into contact with the corner 21a and be pushed forward from behind. That is, this cover 40
This constitutes the rotating lever of the present invention. The supporting wall 13 has a small projection 13b for temporary holding formed on the front side alongside the rotating shaft 13a, and when the cover 40 is erected, as shown in FIG. Are stuck and are held lightly.

In the present embodiment, the rotary lever is constituted by the cap-shaped cover 40. However, at least the rotary lever can be rotated with respect to the housing 10 so that the pushing end 42 at the rear end can enter the cavity 11. , And the pushing end 42 is rotated by the rotating operation to
It suffices if the terminal fitting 20 in 1 is pushed from the rear side to the front side. Therefore, the plate piece is rotatably supported on the upper surface of the housing 10, and when the front end of the plate piece is lifted, the rear end enters the cavity 11 while rotating from the rear side to the front side. You may keep it. Of course, various configurations can be adopted as the configuration for rotatably supporting in this manner.

Further, in the present embodiment, the pushing end 42 is formed wide so that the three cavities 11, 11, and
Although it is designed to enter the cavity 11 integrally, it is also possible to enter the cavity individually. The cap-shaped cover 40 slides back and forth in a horizontal state to cover the front end portion of the housing 10, and
The joint terminal 50 is press-fitted and held on the back side wall surface facing the front end surface of the first terminal. The joint terminal 50 faces the respective cavities 11, 11, 11, and has a male tab-like terminal piece 51,
When the cover 40 slides rearward, the respective terminal pieces 51 enter the respective cavities 11 and are fitted and connected to the terminal portions 21 of the internal terminal fittings 20.

When sliding backward, the pushing end 42 moves backward with the window end 14 protruding from the window portion 14.
The window 14 is covered at the top. In the rear end position, the front end of the pushing end 42 enters and is held in the arch 15 formed in the width direction at the rear end of the upper surface of the housing 10. In the present embodiment, the joint terminal 50 is held by the cover 40. However, the joint terminal 50 does not necessarily need to be held.
The window 14 can be closed with. Alternatively, the end of the cover 40 may be formed in a cylindrical shape so that the mating connector can be mounted from the front. Of course, it is also possible to hold the joint terminal 50 in this way and use it as a joint connector. Furthermore, in the case where the joint terminal 50 is not provided, the cover 40 is attached only during the transportation so that the opening is not inadvertently released.
May be removed and attached to the mating male connector provided with the hood.

Next, the operation of this embodiment having the above configuration will be described. As shown in FIG. 3, the cover 40 is attached to the housing 10, and the terminal fitting 20 with the wire 30 crimped to the rear end is inserted into the cavity 11 from the rear side of the housing 10. As shown in FIG. 4, when the rear end corner 21 a of the upper surface of the terminal portion 21 of the terminal fitting 20 is inserted to the vicinity of the window 14 on the upper surface of the housing 10, the tip of the cover 40 is rotated so as to be lifted upward. . As the cover is rotated, the pushing end 42 of the rear end of the cover 40 enters the cavity 11 through the window 14 while rotating from the rear side to the front side while rotating, and contacts the corner 21 a of the terminal fitting 20 from the rear side. Touch Then, as shown in FIG. 5, when the cover 40 is in an upright state with respect to the housing 10, the terminal fitting 20 is pushed forward at the pushing end 42 to be in the normal position, or the terminal
