Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a charging device used to charge a battery in a battery-powered cordless telephone or the like.

BACKGROUND ART FIG. 3 shows an example of this type of charging device, in which a handset 10 serving as a case for a battery-powered electronic device is inserted through an opening 2 of a charger 1, and An elastic and conductive charging terminal 8 is brought into contact with the upper bottom 3 of the bottom, protrudes from a hole 5 formed in the side wall 4 of the opening 2, and has one end 7 fixed to a printed base 6 inside the double bottom. The tip 9 is
It engages with the recess 10a of the handset 10, and from the charging terminal 8,
The configuration is such that current is supplied to a battery (not shown) inside the handset 10 via a recess 10a connected to the battery.

Problems to be Solved by the Invention However, in the conventional charging device 1 described above, since the tip portion 9 of the charging terminal 8 is exposed from the hole 5 in the side wall 4, (1
There were problems such as:) the charging terminal 8 is susceptible to deterioration due to corrosion due to the adhesive, (2) there is a risk of electric shock, and (3) frictional resistance with the handset makes insertion and removal difficult.

It is an object of the present invention to eliminate the drawbacks of the above-mentioned conventional examples and to provide a charging device in which charging terminals are not exposed.

Means for Solving the Problems In order to achieve the above object, the present invention has a slide that moves when a handset is inserted into the charger, and a slide that is normally housed in a side wall and that protrudes in conjunction with the movement of the slider. The device is configured to include a charging terminal for charging the battery.

Function Since the present invention is configured as described above, it has the effect that the charging terminal of the charging device is not exposed.

Embodiments FIGS. 1 and 2 show the configurations of first and second embodiments of the present invention, respectively.

In FIG. 1, 20 is a charger, 21 is the double-bottomed upper bottom of the opening 34, 22 is a slide rod protruding from a hole 35 provided in a part of the upper bottom 21, and 23 is a slider. An inclined surface 24 contacts a lower end 36 of the slide rod 22. A vertical surface 32 of the slider 23 opposite to the inclined surface 24 is pressed by a spring 31 housed in a holding portion 30 . Reference numeral 25 denotes a charging terminal, the lower end of which is fixed to the flat part 28 of the slider 23, the upper end 26 of which is bent into a V shape, and is entirely made of an elastic metal plate. 27 is the hole, 29
is a movement stopper of the flat portion 28.

Next, the operation will be explained. When the handset 10 is inserted (placed) in the opening 34 of the charger 20, the handset 10 is inserted into the upper base 21.
The slide rod 22 protruding from the hole 35 is pushed down against the spring force of the spring 31, and the slider 23 moves to the left by a component of this pushing down force. The terminal 25 also moves to the left, and the upper end 2
6 emerges from the hole 27 in the side wall and is exposed. As a result, the upper end portion 26 and the recessed portion 10a are engaged and charging is performed. When the handset 10 is lifted up when charging is finished, the slider dent moves to the right until it comes into contact with the stopper 29 due to the repulsive force of the spring J31. is restored, and the upper end 26 of the charging terminal 25 also moves to the right and is housed inside the hole 27.

Note that the recess 32 provided in the handset 10 and the recess 33 provided at one end of the upper base 21 are designed to engage with each other when the handset 10 is inserted, thereby making the handset 10 more stable to hold. be.

In FIG. 2, 40 is another charger, 41 is a crank as a type of slider, 42 is a holding part provided at the bottom 46 of the charger 40, and 43 is a crank 41 held by the holding part 42.
44 is a charging contact provided at the tip 48 of the vertical portion 54 of the crank 41; 45 is a spring provided between the inner wall 47 of the charger 40 and the tip 48; 49 is a 50 is a hole, 51 is an upper base, 52 is a recess, and 53 is a convex portion.

With the above configuration, when the handset 10 is placed on the upper base 51 of the charger 40, the crank 41 rotates counterclockwise around the shaft 43, and therefore the tip 48 of the crank 41 is also rotated by the spring 45.
rotates counterclockwise against the spring force of contact 4.
4 is exposed from the hole 50, and the contact 44 comes into contact with the recess 10a (!) of the handset 10, as in the case of FIG. Also the first
Same as the figure.

Note that the charger may be provided separately or may be incorporated as a part of the cordless telephone. The slide rod 22, the slider 3, the charging terminal 25, etc., or the crank 41, etc. all constitute a connecting means.

Effects of the Invention As is clear from the above embodiments, the present invention is configured such that the charging terminal contacts the handset and the like to perform charging only after the case of the handset and the like is housed in the charger. There is no need to worry about deterioration and electric shock due to adhesion of foreign objects when the charger is not in use, and also has the advantage that the charging terminal does not get in the way when inserting the handset into the opening.
