Next, the first connector 25 and the second connector 2
The procedure for connecting the first terminal 23 and the second terminal 27 by fitting the first terminal 23 and the second terminal 27 will be described. First, the connector housing 43 of the second connector 29 is fitted into the fitting hood 37 of the first connector 25. In this state, as shown in FIG. 2A, the plurality of connection pieces 31 are all located on the other side wall 53 side (unconnected position) in the accommodation recess 47. Also,
The slider 33 is located at the lock portion 85, and the lock convex portion 97 is engaged with the lock concave portion 99. After the engagement of the lock portion 85 is released from this state, the slider 33 is moved from the lock portion 85 side to the lock portion 87 side (the direction of the arrow b).

When the slider 33 is moved in the direction of arrow b,
The round convex portion 65 of the connection piece 31 is moved from the entrance opening 111 to the cam groove 6.
9 in order, through the inclined portion 115 and the outlet 11
Exit from 3. As a result, the connection pieces 31 sequentially move as shown in FIG. 6 and move from the non-connection position shown in FIG.
The connection piece 31 slides to the connection position shown in FIG. 2B to connect the second terminal 27 and the first terminal 23. And
When the slider 33 is moved to the lock portion 87, all the connection pieces 31 are moved from the non-connection position to the connection position (arrow a in the figure).
Direction) and the plurality of second terminals 27 and first terminals 23 are connected. In this case, the regulated wall 79 of the connected piece 31 that has moved next is placed on the regulated wall 79 of the connected piece 31 that has moved earlier.
Abuts on each other, the first connection piece 31 is restrained at the connection position. When the last connection piece 31 is positioned at the connection position, the lock projection 107 is engaged with the lock recess 109 of the cam groove 69 of the slider 33. This allows
When the last connection pieces 31 are locked by the connector housing 43, the plurality of connection pieces 31 are restrained at the connection positions. Therefore, the connection state between the first terminal 23 and the second terminal 27 is maintained.

Next, the first connector 25 and the second connector 2
In order to release the engagement with the lock portion 9,
After releasing the lock state to the lock 7, the slider 33 is moved to the lock section 85 side. Slider 33 into lock section 85
When it is moved to the side, the connection pieces 31 sequentially move to the non-connection position side, and the connection between the first terminal 23 and the second terminal 27 is released.

According to this embodiment, the regulation wall 77 of the next connection piece 31 that has moved to the next connection position comes into contact with the regulated wall 79 of the connection piece 31 that has previously moved to the connection position. Since the top 31 is held at the connection position, a separate lock component is not required.

Further, since the connection operation for connecting the first terminal 23 and the second terminal 27 and the operation for maintaining the connection can be performed in one operation, the connection operation is facilitated.

If another connector having a different number of poles between the first terminal 23 and the second terminal 27 is to be manufactured, the connecting piece 31
And the slider 33 can be shared, so that only the connector housing and the cover need to be manufactured. Therefore, the manufacturing cost can be significantly reduced.

[0040]

As described above, according to the first aspect of the present invention, the first connection piece moved to the first connection position is engaged with the next connection piece moved to the next connection position. The connected frame moved to the connection position is restrained by the connection position. Therefore, a separate lock component for holding the connection piece at the connection position becomes unnecessary, and the manufacturing cost can be reduced.

According to the second aspect of the present invention, the plurality of connection pieces can be respectively restrained at the connection positions by fixing the slider to, for example, the first connector by the locking means.

According to the third aspect of the present invention, there is provided a slider which is slidably provided on one of the first connector and the second connector and which sequentially moves the connection piece from the non-connection position to the connection position. Thus, the connection operation between the first terminal and the second terminal and the operation for maintaining the connection state can be performed in one operation, and the connection operation can be easily performed.

According to the fourth aspect of the present invention, the regulating wall of the next connection piece that has moved to the next connection position comes into contact with the regulated wall of the previous connection piece that has moved to the connection position first. Is restricted to the connection position and restricted to the connection position. Therefore, if the connecting pieces are sequentially moved to connect the first terminal and the second terminal, the connecting piece connecting the first terminal and the second terminal is restrained at the connecting position by the next connecting piece. Therefore, a separate locking means for holding the connection piece at the connection position is not required.

According to the fifth aspect of the present invention, all the connection pieces are moved to the connection position, and then the slider is fixed to one of the first connector and the second connector by the lock means. The top can be restrained at the connection position.
