Electronic Device and Connector Fitting Method
First Claim
1. An electronic device characterized by comprising:
- an external device connecting connector which is connected to a power supplying connector of an external device having a power supplying function and receives power supplied from said external device;
an electronic circuit which performs predetermined operation upon reception of the power supplied from said external device through said external device connecting connector; and
an electromagnet which is provided to said external device connecting connector and electrically connected between said external device connecting connector and said electronic circuit, generates a magnetic force when a power supply current supplied from said external device flows therethrough, and attracts a predetermined portion formed of a magnetic body of said power supplying connector, to maintain a fitting state between said external device connecting connector and said power supplying connector.

Abstract
An electronic device (30) of the this invention includes an external device connecting connector (33) to be connected to a power supplying connector (40) of an external device (41) having a power supplying function, an electronic circuit (31) which performs predetermined operation upon reception of power supplied from the external device through the external device connecting connector, and an electromagnet (32) which is provided to the external device connecting connector and electrically connected between the external device connecting connector and the electronic circuit. The electromagnet generates a magnetic force when a power supply current supplied from the external device flows through it, and attracts a predetermined portion formed of a magnetic body of the power supplying connector, to maintain a fitting state between the external device connecting connector and the power supplying connector. Thus, the fitting state becomes reliable. When supply of the power supply current from the external device is stopped, the fitting state is canceled. Thus, the power supplying connector can be pulled out from the external device connecting connector readily, so that any damages can be prevented.

8. A connector fitting method characterized by comprising:
-
the step of fitting a power supplying connector of an external device having a power supplying function to an external device connecting connector of an electronic device which receives power from the external device; and the step of fitting the two connectors so that an electromagnet which is provided to the external device connecting connector and electrically connected between the external device connecting connector and the electronic circuit generates a magnetic force when a power supply current supplied from the external device flows to an electronic circuit of the external device, and attracts a predetermined portion formed of a magnetic body of the power supplying connector, thus maintaining a fitting state between the external device connecting connector and the power supplying connector. - View Dependent Claims (9, 10)
