A power supply connector 6 having a contact piece (not shown) that can be in contact with a charging terminal provided in the power supply 4, and a DC current output from the AC adapter 2 is supplied to the contact piece of the power supply connector 6. And a power supply cable 7.

As shown in FIG. 9, the interface connector 4 of the portable telephone 3 is usually covered with a protective cover 8 to protect the interface connector 4 from rain water and dust.

When charging the battery built in the mobile phone 3 using the wireless telephone charging device shown in FIG. 7, the protective cover 8 covering the interface connector 4 is removed from the mobile phone 3. In addition, the power supply connector 6 is inserted into the interface connector 4, and the contact piece of the power supply connector 6 is brought into contact with the charging terminal in the interface connector 4 of the mobile phone 3.

Then, plug 1 of AC adapter 2 is connected to AC
DC power output from the AC adapter 2 is supplied to the charging terminal in the interface connector 4 through the connection piece of the power supply cable 7 and the power supply connector 6, and is supplied to the battery of the mobile phone 3. Charge the battery.

[0007] This wireless telephone charging device is excellent in portability because it is composed of the AC adapter 2 and the power supply connector 6 having relatively small external shapes, and the power supply cable 7 having flexibility.

FIG. 8 shows another example of a conventional wireless telephone charging apparatus. This wireless telephone charging apparatus includes an AC adapter 2, a power supply connector 6, and a power supply cable 7 as described above. And a table 9.

The pedestal 9 has a concave portion 10 into which a portion near the connector installation end of the mobile phone 3 is inserted from above. The mobile phone 3 into which the connector installation end portion is inserted is inserted into the recess 10. The antenna can be supported in a standing state in which the front end of the antenna is slightly inclined backward.

On the inner bottom surface of the recess 10, two charging terminals 5 (see FIG. 9) of the portable telephone 3, which are separately provided from the charging terminals of the interface connector 4 described above, can come into contact. A contact piece (not shown) is provided, and a power receiving terminal (not shown) is provided on the rear surface of the mounting table 9 to be able to come into contact with the contact piece of the power supply connector 6 when the power supply connector 6 is inserted. Is provided, and the power supply contact piece and the power receiving terminal are electrically connected via a lead wire (not shown).

When charging the battery built in the mobile phone 3 using the wireless telephone charging device shown in FIG. 8, the power feeding connector 6 is inserted into the power receiving connector 11 of the table 9. The contact piece of the power supply connector 6 is brought into contact with the power receiving terminal of the power receiving connector 11.
