[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detachable connector for making an electrical connection between a main body and an operation panel in an automobile stereo or the like in which a main body and an operation panel are detachable. .

[0002]

2. Description of the Related Art A conventional detachable connector of this type comprises a main body-side connector attached to a main body and an operation panel-side connector attached to an operation panel. Several contacts protrude from the connector on the main body,
A contact portion corresponding to the contact is exposed in the operation panel portion side connector. The contact has a contact portion bent in a substantially rectangular shape, and the contact portion is bent to the back side of the main body side connector.

[0003]

However, this type of detachable connector of the related art has a problem that the operation panel portion may be bent and deformed when used for a long period of time. This is because the contact pressure between the main body side connector and the operation panel portion side connector, that is, the contact pressure between the contact and the contact portion, all acts in the same direction as the attachment / detachment direction of the operation panel portion. In particular, the bending deformation of the operation panel is likely to occur in summer when the temperature inside the vehicle rises. Such bending deformation not only impairs the electrical connection between the main body and the operation panel, but also greatly reduces the commercial value of the stereo for an automobile.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a detachable connector in which an operation panel portion is not bent and deformed even when used for a long period of time.
