[0008]

However, in the above-mentioned conventional structure, the plug 1 is inserted into the interface connector 25 with the portable battery pack 20 mounted.
When 9 is inserted and power is supplied from the car battery, the portable battery pack 20 is connected by a relay or the like.
It is necessary to electrically disconnect the battery or, conversely, to configure a circuit to charge the portable battery pack 20. In this case, there is a problem that the volume of the circuit and the mechanism portion increases, and as a result, the size of the mobile phone main body 26 itself increases, which is an obstacle to miniaturization.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide an interface connector capable of downsizing the apparatus body and improving portability.

[0010]

In order to achieve this object, the interface connector of the present invention plugs when the battery pack is mounted on the main body of the apparatus, contacts the power terminal of the battery pack, and when the plug is inserted from the outside. A pair of battery terminals equipped with a fixing claw to prevent the plug from being easily removed, a switch terminal that contacts one of the switch terminal contact parts of the pair of battery terminals, and a plug when the plug is inserted. By being pushed, the switch terminal is pushed back so that the switch terminal and the battery terminal are separated from each other.

[0011]

With this configuration, the size of the interface connector is almost the same as that of the conventional interface connector, power can be supplied from an external power source by connecting with an external device, signals can be exchanged with the external device, and the plug can be easily removed. Power can be supplied from the pack to the main circuit and the battery pack can be automatically disconnected from the main circuit when the plug is inserted.
