DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a charging device for a wireless telephone.

[0002]

2. Description of the Related Art In recent years, various wireless telephones such as a portable telephone or a cordless handset attached to a wired telephone have become widespread. Such a wireless telephone obtains power required for transmission and reception. Built-in battery.

FIG. 7 shows an example of a conventional wireless telephone charging device. This wireless telephone charging device uses an AC current obtained by a plug 1 inserted into an AC outlet (not shown) for indoor power supply. (AC 100 V) to a predetermined voltage value and an AC adapter 2 for rectifying the voltage, and the interface connector 4 when inserted into the interface connector 4 installed at the end of the mobile phone 3 near the antenna.
Contact piece (not shown) that can come into contact with the charging terminal provided inside
Power supply connector 6 having
And a power supply cable 7 for transmitting the DC current output from the power supply to the contact piece of the power supply connector 6.

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.

This wireless telephone charging apparatus has a stand 9 which can support the mobile phone 3 in an upright state in which the front end of the mobile phone near the antenna is slightly inclined backward, so that the mobile phone 3 is being charged. Even in this case, the reception failure due to the decrease in the antenna gain does not occur, and the visibility of the light emitting diode display unit 12 and the liquid crystal display unit 13 of the mobile phone 3 does not decrease.

[0015]

However, the charging device for a wireless telephone shown in FIG.
Is placed directly on a desk or the like in a sideways position, resulting in poor reception due to reduced antenna gain,
The light emitting diode display section 12 and the liquid crystal display section 13 are difficult to visually recognize.

In addition, since the protective cover 8 needs to be removed from the mobile phone 3 for charging, if the protective cover 8 is lost or if the user forgets to attach the protective cover 8 after charging is completed, the interface connector is required. 4
May be soiled.

The guaranteed number of insertion / removal of the interface connector 4 and the power supply connector 6 is generally about 5000 times, and there is a concern that the interface connector 4 and the power supply connector 6 may be deteriorated and damaged by the insertion / removal during charging. You.

In the charging device for a wireless telephone shown in FIG. 8, a large mounting table 9 surrounding the connector installation end portion of the mobile phone 3 is interposed between the mobile phone 3 and the power supply connector 6. Not good.

Furthermore, in any of the wireless telephone charging devices shown in FIGS. 7 and 8, a connector (not shown) connected to a microcomputer, a facsimile or the like is connected to the interface connector 4 during charging. Therefore, data cannot be transmitted / received via the mobile phone 3.
