Multiple types of dedicated chargers with connectors that match the connectors are required. In addition, when considering going out, etc., multiple types of portable external power sources must be prepared.

Also, in portable electronic devices such as game consoles and digital cameras, charging connectors differ from mini USB connectors, round pin plugs, etc. due to differences in sales companies and models, etc. And multiple external power supplies are required.

Against this background, chargers and the like having a plurality of types of charging connectors have been proposed. For example, Patent Document 1 discloses a battery pack portion in which a plurality of thinly connected batteries are arranged in the same plane, a fixing means for detachably attaching the battery pack portion to the back surface of a mobile phone, and a battery pack. A connecting terminal portion (similar to a charging connector) having a pair of elastic lead terminals connected to the positive and negative electrodes of the portion, and a contact contact on the other end side of the elastic lead terminal can be elastically contacted with a charging contact of a mobile phone A mobile phone charger having the above function is disclosed.

Such a charger for a mobile phone can be reduced in size, thickness, and weight, can talk while being charged, and includes first and second connection terminal portions corresponding to charging contacts of a mobile phone that are roughly divided into two types. In addition, only by selectively connecting these connection terminal portions to the battery pack portion in a detachable manner, it can be adapted to drive and charge all types of mobile phones.

By charging the mobile phone or the like with b, or by inserting the connector b into the connector B of the charger body, the mobile phone or the like can be charged with the connector a. In such a general-purpose charger for mobile communication devices, for example, two types of mobile communication devices can be charged with one charging cable.

Patent Document 3 discloses a mobile phone connector and a mobile phone charging device having a plurality of types of connection connectors (charging connectors) individually connected to interface connectors of a plurality of types of mobile phones having different fitting shapes. Has been. Also disclosed are a mobile phone connector and a mobile phone charging device in which a plurality of types of connection connectors are arranged in a connector body, and all of these connection connectors can be changed to positions where they are fitted to corresponding interface connectors. Yes. Further, there is disclosed a connector for a mobile phone that can charge a mobile phone by providing a battery connection terminal (terminal) to which a battery can be connected and connecting the battery and a commercial power source (a DC power source obtained by rectifying the commercial power source). That is, by changing the connection connector (charging connector) to a position where it is fitted to the interface connector, it can be connected to a plurality of interface connectors of a mobile phone, and a plurality of types of mobile phones can be driven from a battery or a commercial power source. A technique for charging is disclosed.
