JP2000134807A - Ac adaptor for charging portable telephone set - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain an AC adaptor for charging a portable telephone set, which can be stored and carried satisfactorily. SOLUTION: A charging pedestal 8 has a pair of terminals 9, which are brought into contact with the charging electrodes of a portable telephone set. The one end of a cord 3 is connected to the pair of terminals 9. The charging pedestal 8 is held on a front side in a case cover 7. An AC/DC converter block 1 and the cord 3 are housed in a main case 6 and the case cover 7, when they are not used. In order to charge the telephone set, when the case cover 7 is opened, the AC/DC converter block 1 is taken out and the case cover 7 is turned by an angle 270 deg.+θ (0<θ<=45 deg.) and a top surface plate is brought into contact with the front edge of a bottom surface plate and held at that position with the front edge as a stopper. If the main case 6 is put on an approximately horizontal reference plate with its open top face down in that state, the top surface plate is held with an inclination angle of approximately θ from a vertical plane. The telephone set is made to lean along the inner surface of the top surface plate and the tail part of the telephone is placed on the charging pedestal 8, so as to bring the charging electrodes of the tail part into contact with the terminals.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an AC adapter for charging a mobile phone.

[0002]

2. Description of the Related Art As shown in FIG. 7, a conventional AC adapter for charging a portable telephone (hereinafter simply referred to as an AC adapter) includes an AC / DC converter block 1, an I / O plug (16P) 2, and a And a charging stand 4. When charging the mobile phone 5, the I / O plug 2 is fitted into an I / O socket 4a provided on the side of the charging stand 4, and the tail of the phone 5 is inserted into the phone engagement hole 4b. Then, a terminal (not shown) provided on the bottom surface of the engagement hole 4b is connected to the mobile phone 5 (FIG. 8).
The internal battery can be charged by contacting the charging electrode 4a exposed at the tail portion of the battery. The AC / DC converter block 1 is provided with a pair of blade-shaped contact pieces that are inserted into an outlet of a commercial power supply. When the AC / DC converter block 1 is not used, the blade-shaped contact piece is housed in the body of the block 1 and, when used, is rotated approximately 90 ° outward so as to protrude from the body.

As shown in FIG. 8, when a tail portion of a telephone is provided with an I / O socket 4b together with a charging electrode 4a, it is bulky at the time of traveling, so that it is not necessary to carry the charging stand 4 without traveling.
