DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cordless telephone for performing wireless communication between a telephone body connected to a telephone line and a handset,
In particular, the present invention relates to a cordless telephone equipped with a charging structure for a handset power supply battery, which is suitable for wall hangings.

[Prior Art] As is well known, in cordless telephones that perform wireless communication between a telephone body connected to a telephone line and a handset, a rechargeable power source battery such as a lithium battery or a nickel cadmium battery is used as a handset. Since the power supply battery is used to supply power to the internal circuit of the handset, it is necessary to charge the same power supply battery of the handset with the consumed power.

For this reason, conventionally, a charger for charging the power supply battery is built in the telephone body or a separately prepared charging tray, and the handset is held in the standby position of the telephone body or the standby position of the charging tray to wait. The power battery is being charged.

[Problems to be Solved by the Invention] However, according to such a conventional charging structure for a cordless telephone, the charging function is started and disconnected separately from the on / off operation of the hook switch. After the call, the hook switch is off and there is no hindrance to the operation, so the user forgets to return the handset to the charging position of the phone body or the charging tray, and the power of the power supply battery is exhausted, making it difficult to talk with the handset There are cases. In the conventional charging structure, when the phone body is hung on a wall and used, it is often necessary to prepare a charging tray at a position completely different from the phone body, and charging is performed separately from the disconnection operation of the hook switch. Since the start and end operations are performed, the handset operation becomes inconvenient.

Even if the handset is hooked and charged at the same time, the means for turning the hook switch on and off is different, so that the hook switch is turned off, the charging is started, and the handset is hooked at once. Not,
Therefore, there are many cases where the handset is left uncharged or the handset is not charged.

[Object of the Invention] In view of the current state of the conventional charging structure as described above, the object of the present invention is that there is no charging error due to misplacement of the handset, and there is no need to charge the handset at a position away from the telephone body. It is possible to obtain a charging structure for a cordless telephone suitable for a wall-hanging type, that is, a structure in which a hook switch can be turned off and a charging operation can be performed at the same time by performing an operation of hooking a handset on a hooking claw.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a recess for accommodating a handset portion of a handset and having a hook button disposed at the bottom thereof for performing a descending or restoring operation by detaching the handset portion. A telephone body which is used by being hung on a wall or the like formed with a hole portion into which a nail block is further inserted in the concave portion, and the handset portion with respect to a hooking nail of the nail block inserted into the telephone body And a handset that can hook the hooking hole formed in the jaw and that is provided for performing wireless communication and has a built-in power supply battery, and a charging contact that uses charging of the power supply battery is provided in the hooking hole of the handset. Place on both sides,
The present invention proposes a structure in which a pair of contact springs that can elastically contact the charging contacts when the hooking holes of the handset are hooked on the hooking claws are projected to both sides of the hooking claws.

The first embodiment shown in FIG. 1 to FIG. 3 is an embodiment in which the present invention is applied to a wall-mounted desk phone, and the upper portion of the telephone main body 1 used by being hung on a wall is commonly used by both the wall hanging and the desk. Handset recess that accepts handset part 2a of handset 2
It has 1a. That is, a charger (not shown) for charging the power supply battery built in the handset 2 is built in the inside of the telephone body 1, and when the handset recess 2a of the handset 2 is received in the handset recess 1a. , When the hook button 4 provided in the handset recess 1a is pressed to turn off the telephone line and the handset 2 is detached from the handset recess 1a, the telephone line of the telephone body 1 is automatically turned on and the telephone body 1 A cordless call can be made between the telephone line and the handset 2.

Then, a mounting hole 6 into which the nail block 5 is inserted is formed at the bottom of the handset recess 1a.
The wall hook claw 7 is engaged with the hook hole 8 formed in the jaw of the handset 2a of the handset 2 to prevent the handset 2 from falling off the telephone body 1. That is, there are guides 6a extending in the depth direction on the left and right of the mounting hole 6, and the wall hooking claws 7 have guide grooves 9d on the left and right sides which can be slidably inserted into these guides 6a, as shown in FIG. Block body 9 equipped
Is integrally molded into. As shown in FIG. 2, a locking hook 9a (shown in FIG. 2) for preventing the claw block 5 from coming out of the mounting hole 6 is integrally formed on the back surface of the block body 9.

FIG. 3 is an exploded view of the claw block 5, and a left and right holding piece capable of holding an intermediate portion 11b of a pair of contact springs 11 having a base portion 11a fixed by a mounting screw 10 on the surface of a resin-molded block body 9. 9b and 9c are formed by protrusion. Although illustration is omitted, the contact spring 11 composed of a leaf spring is connected to the charger built in the telephone body 1 and is extended in the intersecting direction. The left and right windows of the cover 12 formed at the left and right positions of the wall hanging claw 7.
It is projected from 12a to the outside.

In addition, charging contacts 13 are provided on the left and right of the hook hole 8 of the handset portion 2a at positions corresponding to the tips 11c of the contact springs 11. Although not shown, these charging contacts 13 are not shown.
