〔Example〕

Hereinafter, the gist of the present invention will be described in detail with reference to the embodiments shown in the drawings.

The lower and upper members constituting the stack structure 1, for example, the coupling device 2 between the main and sub circuit boards 1b and 1a is a perspective view of FIG.
As shown in the side view of the figure and the enlarged exploded perspective view of the main part of FIG. 3, it is composed of a first coupling member 2a and a second engagement member 2b.

The first coupling member 2a is provided with penetrating engagement pins 2a-4 through both bent pieces 2a-1 and 2a-2 formed by bending both ends in the longitudinal direction of a strip-shaped sheet metal into a right-angled U-shape. The piece 2a-3 is provided with a screw hole 2a-5 for attaching the upper member of the stack structure 1, for example, the sub circuit board 1a.

The second coupling member 2b is formed by bending both ends of the strip-shaped sheet metal in the longitudinal direction into a U shape so as to be fitted and slidable on the outer surfaces of the two bending pieces 2a-1, 2a-2 of the first coupling member 2a. First on both bent pieces 2b-1, 2a-2
Inserting and sliding the engaging pin 2a-4 of the connecting member 2a, the initial moving length in the separating direction (the play length of the connector 3 for electrically connecting the main and auxiliary circuit boards 1b and 1a is several mm Second vertical groove, horizontal groove and first vertical groove on the edge side of the bent piece, which have an added length) and are bent at a right angle to the separating direction and are bent again in the separating direction to open at the edge. A guide groove 2b-4, and a screw hole 2b-5 for attaching a lower member of the stack structure 1, for example, the main circuit board 1b, is formed in the U-shaped intermediate piece 2b-3.

In addition, the U-shaped intermediate pieces 2a-3 of the first and second coupling members 2a and 2b,
Positioning protrusions 2a-6 and 2b-6 are integrally provided on one end of 2b-3, respectively.

To connect electrical signals with the plug-in connector 3 shown in FIG. 1 and connect optical signals with optical cords 4 using the coupling device 2, the primary and secondary circuit boards 1b and 1a are coupled to each other. The coupling member 2a of No. 1 has its positioning protrusion 2a-6 engaged with the end surface of the sub-circuit board 1a, and is attached by the mounting screw 5. Second
For the coupling member 2b of the above, the positioning projections 2b-6 are inserted into the positioning holes 1b-1 which are preliminarily aligned and drilled so that the connector 3 can be plugged in corresponding to the four corners of the sub-circuit board 1a. Attach with 6. Then, the connector 3 is plugged in while the engagement pin 2a-4 is inserted and guided in the guide groove 2b-4 that is bent in a hook shape. After connecting the connector 3,
It is screwed to a conventional spacing member (not shown) interposed between the main and sub circuit boards 1b and 1a.

The separation of the sub-circuit board 1a from the main circuit board 1b is shown in FIG. 4 (a), (b), (c) which is a side view (however, the engagement state of the connector 3 is not shown) showing the separation process sequence. As shown in the drawing, after removing the mounting screws fixed to a conventional spacing member (not shown), the sub-circuit board 1a is lifted in the separating direction (upward) to disconnect the connector 3 and the engaging pin 2a-4 is moved to the initial length ( distance)
It moves in the direction of the upward arrow A by L (see FIG. 4 (a)), then shifts in the direction of the right arrow B (see FIG. 4 (b)), and further lifts in the upward arrow C direction (see FIG. 4). (See FIG. 4 (c)).

In this way, the second coupling member attached to the lower member of the stack structure and the first coupling member attached to the upper member of the stack structure are fitted to each other and the engagement pin of the first coupling member 2a By inserting and sliding 2a-4 into the guide groove 2b-4 of the second coupling member 2b, the mutual relation of the stack structures is automatically positioned when the stack structures are coupled. It can be plugged in at the same time as coupling, and only the optical cord needs to be considered.

Further, when the upper member of the stack structure is separated, the engaging pin engages with the guide groove to temporarily move the initial moving distance from the lower member,
Limit to a safe range (In the example, after disconnecting the connector,
It is possible to add a little play (several mm) to the extent that the optical cord is not accidentally cut], and further, the engaging pin can be slid along the guide groove to separate the stack structure. for that reason,
When the connector is detached as in the conventional case, the problem of pulling and cutting the optical cord with excessive force can be solved.
