A conventional example known as this type of connector connection structure will be briefly described with reference to FIGS. 7 and 8. On the electronic device housing 1 side such as an instrument housing, a large number of printed wiring boards 2 are provided. A fixed-side connector 3 having a male contactor 3a and the like is provided, and a guide plate body 4 bent and formed in a substantially U-shape is provided on the front side of the fixed-side connector 3.
The movable side member 6 having the above-mentioned features is fitted between the side edge portions 4a, 4b on both sides of the guide plate body 4 and guided on the slide plate body 7 which is bent and formed in a substantially reverse U-shape. It is provided. When the side edges 7a and 7b on both sides of the slide plate body 7 are slid and guided along the insides of the side edges 4a and 4b of the guide plate body 4, respectively, the fixed side A movable side connector 8 having a female contactor 8a coupled to each contactor 3a of the connector 3 is provided via a printed wiring board 9 and the like. Reference numeral 10 in the drawing denotes a connector attaching / detaching operation lever rotatably supported by a support shaft 10a on a side wall of a part of the movable member 6, and the lever tip is provided on the guide plate body 4 side. An engaging groove 10a for engaging with the engaging pin 11 is formed, and by rotating the lever 10 in a state where these are engaged, the connectors 3 and 8 can be coupled or separated from each other. Was becoming.

[Problems to be solved by the device]

However, according to the above-described conventional structure, a thin metal plate material or the like is bent into a substantially U-shape as a simple guide means for sliding and detaching the electron supply housing 1 side and the movable side member 6. Using the formed guide plate body 4 and slide plate body 7, these are opposed to each other and combined, and side edge portions 4a, 7a; 4b, 7b are fitted together in a state of contacting each other, The slide plate body 7 may be combined with the guide plate body 4 as shown by the imaginary line in FIG. 8, but as shown by the solid line by mistake, the slide plate body 7 is placed outside the one side edge 4a of the guide plate body 4. ,
If the side edge portions 7a are combined in a position, the connectors 3 and 8 are displaced from each other, and the required connector connection cannot be performed. In particular, even in the above-mentioned combined state, the slide plate body 7 can slide on the guide plate body 4, and the amount of deviation thereof is as small as the thickness of the thin plate material forming the side edge portion 4a. Therefore, if the operator does not notice it, the connectors 3 and 8 will be forcedly coupled to each other, whereby the connector pin which is the male contactor 3a is inserted while being inclined toward the female mold side. There is a possibility that it may cause bending, breakage, or the like, and may cause problems such as being incapable of being detached or attached, or being unable to operate the main equipment due to poor connection. Such a problem is remarkable when the connectors 3 and 8 are forcibly connected to each other by the attaching / detaching lever 10 as in the above-described conventional example, and some measures can be taken to solve such a problem. Is desired.
