Has been fixed. On the outer surface of each side plate 21B, a linear slider guide 21C is formed so as to protrude.

[0004] Each side plate 21B has an n-step groove (not shown).
The operation frame 23 is mounted in the groove of each step so as to be movable in a direction orthogonal to the paper surface in FIG. Each of the operation frames 23 is symmetrical, and has connectors 25 on both sides near the center, and mold bosses 23A on both ends.

A slider 24 is employed as a means for moving each operation frame 23. The slider 24 includes a pair of cam plates 2.
4A and a connecting plate 24B for connecting both cam plates 24A to form a U-shape. A linear guide groove 24B and an operation frame driving cam groove 24C are formed from the lower end of each cam plate 24A, and the operation frame driving cam groove 24C is linearly shaped with the mold boss driving groove 24D and the mold boss holding groove. Groove 24E
Are configured continuously.

Next, the connection and disconnection of the connector will be described. The two cam plates 24A of the slider 24 are inserted between the two side plates 21B of the main body 21A of the operation frame housing 21 and the respective guide plates 22.
Push down from the positions (a) and (b) toward the position (c). Then, each guide groove 24B of the slider 24 is guided by the slider guide 21C of each side plate 21B. First, each mold boss driving groove 24D is provided on the operation frame 23 mounted on the uppermost groove of both side plates 21B. Press both mold bosses 23A. Therefore, since the operation frame 23 moves, the two connectors 25 held by the operation frame 23 respectively fit into both header connectors (not shown) provided on the back side of the operation frame housing 21. Subsequently, since each mold boss holding groove 24E holds each mold boss 23A, the fitting between both connectors 25 and both header connectors is maintained.

When the slider 24 is further depressed, the operation frame 23 mounted in the second groove from the top of the operation frame housing 21 is also moved to the operation frame 23 mounted in the top groove.

It is a range of two dashed lines in (b). The slider 24 cannot be removed from the operation frame 23 when the connector is fitted.

To detach each connector 25 from each header connector, the connecting plate 24B of the slider 24 located in the state shown in FIG. 6C is lifted upward.
Then, contrary to the case of the fitting described above, the operation frame 23 is sequentially moved from the operation frame 23 mounted on the lowermost groove to the operation frame 23 mounted on the uppermost groove. As a result, each connector 25 reaches a position separated from each header connector.

Japanese Patent Laid-Open Publication No. 2000-123914 describes a connector drive mechanism in which a pin-side connector and a socket-side connector are fitted and disengaged by moving a slider. However, although the pin-side connector and the socket-side connector are locked in the fitted state, the connector is large and complicated because a lock plate, a wire, a pulley and the like are employed.

[0010]

The conventional connector driving mechanism has the following disadvantages. That is, the connector
Locked in the fitted state, but not locked in the disengaged state. Further, since a large operation space for the slider is required, it is difficult to reduce the size of the connector driving mechanism. Furthermore, in the state where the connectors are fitted, it is impossible to remove the slider, so one connector drive mechanism requires one slider.

Therefore, the present invention solves the drawbacks of the conventional connector drive mechanism, locks the connector drive mechanism in both the fitted state and the disengaged state, and makes it easy to reduce the size of the connector drive mechanism. An object of the present invention is to provide a connector drive mechanism with a fitting lock that can share a slider with a plurality of connector drive mechanisms.
