The connector body 5a is configured to slide within the range of the clearance 5d to absorb mechanical errors with the connector 10a on the electronic device body side and to be properly fitted. You. However, the conventional plug-in module shown in FIG. 12 has a problem that the connector body 5a is restricted by the wiring 6. Connector body 5a
Is restricted by the wiring 6, it cannot slide within the range of the clearance 5d. Then, the connector main body 5a cannot absorb a mechanical error with the connector 10a on the electronic device main body side, and a mating failure occurs. It is considered that such a problem occurs when the position where the wiring 6 is fixed is inappropriate. For example, as shown in FIG. 12, in the conventional plug-in module, the wiring 6 derived from the connection portion 5b having a predetermined height with respect to the plug-in module wall surface 8a is a module that is short in distance from the connection portion 5b.

The wiring 6 needs to be fixed at a predetermined distance from the connecting portion 5b and at the same height as the connecting portion 5b. However, wiring 6
It is difficult to determine the position to fix the. In the first place, the strength of the wiring stress is determined by various factors such as the type, thickness, hardness, and number of wirings of the wiring 6. Therefore, the position at which the wiring 6 is fixed differs depending on the specifications of the manufactured plug-in module. That is, the wiring 6
The optimal position for fixing is not uniquely determined, but needs to be determined according to the wiring 6 to be mounted.
In addition, when a fitting failure due to wiring stress occurs, it is necessary to perform fine adjustment of the mounting of the floating connector 5, change of the position of the wiring clamp 7, and correction of the wiring layout. However, there is a problem that this kind of adjustment work requires time and cost. In addition, as a result of performing this adjustment work, there occurs a problem that a plug-in module that is well fitted with a certain electronic device main body may have a poor fitting with another electronic device main body. May also break compatibility.
