DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal structure of an electronic device, and more particularly, to an attachment to an electronic device main body while sliding the attachment side terminal of the attachment to a main body side terminal of the electronic device main body. The present invention relates to a terminal structure of an electronic device configured to be mounted.

[0002]

2. Description of the Related Art FIGS. 10 and 11 show a charger A and a battery pack B as an example of this kind of conventional electronic equipment.
And a charger A as an electronic device main body includes a pocket Ap into which a battery pack B is inserted.
And a charging terminal C as a main body side terminal,
The battery pack B as an attachment has a contact plate Ba as an attachment-side terminal. When the battery pack B is charged by the charger A, the end of the battery pack B is fitted into the pocket Ap from above the charger A as shown by an arrow V in FIG. By attaching the battery pack B to the charger A while sliding the contact plate Ba, the charging terminal C and the contact plate Ba are brought into contact with each other.

[0003]

In general, the contact plate Ba of the battery pack B is gold-plated or nickel-plated for the purpose of stabilizing contact resistance or the like. There is a problem that an oxide film is formed by leaving the device and the like, and further, dirt adheres. On the other hand, like the above-described charger A and battery pack B, when the battery pack B is mounted on the charger A, the contact plate Ba slides with respect to the connection protrusion Ca of the charging terminal C. In this case, when the battery pack B is inserted into and removed from the charger A, the connection protrusion Ca of the charging terminal C scrapes the oxide film or the like on the surface of the contact plate Ba, so that the surface of the contact plate Ba is cleaned. However,
Foreign matter scraped off from the contact plate Ba concentrates on the contact point between the contact plate Ba and the connection protrusion Ca, so that the contact resistance between the contact plate Ba and the charging terminal C increases, resulting in poor charging of the battery pack B or the like. There is a problem that causes inconvenience. SUMMARY OF THE INVENTION An object of the present invention is to provide a terminal structure of an electronic device that can prevent inconvenience caused by the presence of a foreign substance between a main body side terminal and an attachment side terminal in view of the above situation. is there.

[0004]

In order to achieve the above object, in a terminal structure of an electronic device according to the present invention, a connection is formed in such a manner that an attachment comes into contact with a terminal on a main body side when the attachment is mounted on the main body of the electronic device. A projection is provided, and in a region in front of the connection projection in the moving direction of the attachment mounted on the electronic device main body, when the attachment is mounted on the electronic device main body, it slides on the attachment side terminal prior to the connection terminal, and the attachment is electronically mounted. A cleaning projection is provided to be separated from the attachment when mounted on the device body.
