[0002]

[Prior art]

 Conventionally, this type of inter-device connection connector has been configured as follows, for example. That is, in a car-mounted radio or communication device (for example, car audio), as shown in FIG. 5, the main body 10 of the car audio as the first device and the front operation unit 12 as the second device are detachable. There is something. That is, the main body portion 10 is provided with the front operation portion insertion port 14 on the front surface, and the socket 16 fixed to the sub-board 15 is exposed to the outside at the front operation portion insertion port 14. Further, inside the main body 10, the FPC connector 22 of the main board (main board) 20 is connected to the socket 16 via an FPC (flexible wiring board) 18.

As shown in FIG. 6, in the socket 16, a large number of thin plate-shaped contacts 26 are provided in a housing 24 at equal intervals, and a contacting portion is projected to the outside. The contact 26 is covered with a grounding / protecting plate 28. The grounding / protecting plate 28 is biased by a spiral spring (not shown) so that the contact 26 is normally exposed to a window (not shown). It covers without any damage. A plug 34 fixed to the substrate 33 is provided on the back side of the front operation section 12, and the plug 34 has a large number of contacts 38 at equal intervals in a housing 36, as shown in FIG. It is provided.

In such a configuration, the main body 10 is fixedly attached to the vehicle. Then, when using the vehicle, when the front operating portion 12 is brought into the vehicle and inserted into the front operating portion insertion port 14 of the main body portion 10, the front portion of the housing 36 of the plug 34 is grounded by the socket 16. The protection plate 28 is pressed against the spiral spring around the fulcrum 40, and the contact 26 is projected from the window to be connected to the contact 38. Further, when the plug 34 is pushed in, as shown in FIG. 7, the contact 38 and the contact 26 are completely brought into contact with each other. In this way, the front operation unit 12 is made operable. When getting out of the vehicle, the front operation unit 12 is pulled out from the main body unit 10 and brought back to prevent it from being stolen.
