Description

[Detailed description of the invention] This invention relates to a battery storage device for electrical equipment such as radio receivers and tape recorders.
It is an object of the present invention to provide a battery storage device that has a simple configuration, allows a large area for a printed circuit board to be stored in a cabinet, and has good repair serviceability.

Generally, as shown in FIG. 1, a battery storage device for a portable electrical device is provided with a battery storage recess 2 in a cabinet lid 1, and an electrode terminal plate 5 and a battery storage recess 2 in terminal plate holders 3 and 4 provided on the opposite surface of the recess 2, respectively. electrode spring 6
and hold these electrode terminal plate 5 and electrode spring 6
One end of the battery accommodating recess 2 is made to protrude from the bottom surface of the battery accommodating recess 2 and connected to a printed circuit board housed in a cabinet body (not shown) which is superimposed on the cabinet lid 1 using a lead wire.
However, in a battery storage device with such a configuration, when the cabinet cover 1 is separated from the cabinet main body during repair service, the lead wire will be disconnected because the cabinet main body and the cabinet cover are mechanically connected. The drawback was that the tension made it difficult to perform repair services. On the other hand, in order to eliminate the drawbacks caused by the above-mentioned lead wire coupling method, as shown in FIG.
A rib for 9 is protruded, and an electrode terminal plate 10 and an electrode spring 11 are held in terminal plate holding parts 8 and 9 provided on the rib, respectively, and a part of these electrode terminal plate 10 and electrode spring 11 is attached to the above-mentioned cabinet. Main body 7
It was configured to be brought into contact with the conductive foil portion of the printed circuit board 12 housed inside. However, although the battery storage device with such a configuration improves the repair serviceability itself, since the printed circuit board 12, the electrode terminal plate 10, and the electrode spring 11 are simply in contact with each other, the electrical connection between them is broken. However, if a connector was used to solve this problem, the cost would increase.
Further, the printed circuit board 12 housed in the cabinet body 7 has a disadvantage in that the area itself becomes small because a relief must be provided at the portion where the electrode spring 11 is provided.

The present invention is intended to eliminate such conventional drawbacks, and the present invention will be described below with reference to drawings of embodiments.

Figures 3 to 6 show an embodiment of the battery storage device of the present invention, and in the figures, the inner surface of the synthetic resin cabinet body 21 has battery receiving ribs 22 facing each other. Ribs 23 and 24 are provided in a protruding manner. Furthermore, a boss 25 for mounting a printed circuit board is provided on the inner surface of the cabinet body 21, and a printed circuit board positioning rib 26 is provided protruding from the inner surface of the circumferential surface. The printed circuit board 27 is housed in the cabinet main body 21 and positioned with its edge abutting against the positioning rib 26, and the mounting screw 2
8 to the boss 25. The tips of the ribs 22 protrude from through holes 29 provided in the printed circuit board 27. The synthetic resin cabinet cover 30 is provided with a battery housing recess 31 having a U-shaped cross section and openings 31a and 31b at both ends, and is superimposed on the cabinet body 21 and connected with a mounting screw (not shown). It is becoming more and more common. When the cabinet lid 30 is superimposed on the cabinet main body 21, the bottom surface of the battery storage recess 31 comes into contact with the extended portion 27a of the printed circuit board 27 located between the battery receiving ribs 23 and 24, Openings 31a and 31b at both ends are arranged to face the ribs 23 and 24, respectively. As shown in FIG. 7, the electrode terminal plate 32 has cut-and-raised pieces 32a at both ends and has spring properties in the thickness direction, and also has an engaging piece 32b perpendicular to the plate surface. The electrode terminal plate 32 has a concave groove 23a provided in a battery receiving rib 23 protruding from the cabinet body 21.
The engaging piece 32 is held removably within the
b is brought into contact with the printed circuit board 27, its height is regulated, and is opposed to the opening 31a of the battery storage recess 31. The ends of the lead wires 33 soldered to the terminal portions 32c provided on the electrode terminal plate 32 are soldered to the printed circuit board 27. The electrode spring 34 is a concave groove 24 provided in a battery receiving rib 24 protruding from the cabinet body 21.
The lead wire 35 soldered to the terminal portion of the lead wire 35 is detachably held in the printed circuit board 2.
It is soldered to 7. and the electrode spring 3
4 is opposed to the opening 31b of the battery storage recess 31. Note that the battery 36 is inserted into and taken out of the battery storage recess 31 through an opening provided in the cabinet lid 30, and the battery 36 is placed in the battery storage recess 31 and connected to the electrode terminal plate 3 described above.
2. It is electrically contacted with each of the electrode springs 34.

In the battery storage device having such a configuration, since the electrode terminal plate 32 and the electrode spring 34 are removably formed in the grooves 23a and 24a provided in the battery receiving ribs 23 and 24, the printed circuit board 27 and at the same time, the electrode terminal plate 32,
The electrode spring 34 can be removed, and its repair serviceability is good.
Printed circuit board 2 to avoid pulling 5.
7. The electrode terminal plate 32 and the electrode spring 34 are not cut at the soldered portion. Further, since it is not necessary to cut the printed circuit board 27 to escape the electrode spring 34, the area of the printed circuit board 27 itself can be increased, and the degree of freedom in its design is improved. Furthermore, since the printed circuit board 27 can be held down by using the battery storage recess 31, the printed circuit board 27 can be held down over a wide area, and its installation becomes firm. Furthermore, when the cabinet cover 30 is removed, the battery storage recess 31 disappears, but the electrode spring 3 facing the
4 and the electrode terminal plate 32, the printed circuit board 27 has an extended portion 27a.
The extended portion 27a serves as the bottom for receiving the battery, and the battery can be placed between the electrode terminal plate 32 and the electrode spring 34 during repair service.
This is advantageous for electrical checks.

As described above, according to the present invention, the electrode terminal plate and the electrode terminal plate are connected by lead wires to the printed circuit board housed in the cabinet body in the concave grooves of the battery receiving ribs protruding from the inner surface of the cabinet body so as to face each other. Since the electrode spring is made removable, the electrode terminal plate and electrode spring can be removed at the same time as the printed circuit board, making it easy to repair.
Further, no excessive force is applied to the lead wires, and no breakage occurs at the solder joints. Further, since there is no need to provide a notch in the printed circuit board for escape of the electrode spring, the area of the printed circuit board itself can be increased, and the degree of freedom in circuit design can be increased. Moreover, by providing a battery storage recess with openings at both ends in the cabinet lid that is combined with the cabinet main body, and by bringing the bottom surface of this battery storage recess into contact with the printed circuit board extending between the battery receiving ribs, the battery can be easily removed. Since the electrode springs and electrode terminal plates attached to the receiving ribs are placed in the openings at both ends of the battery storage recess, even if the cabinet cover is removed from the cabinet body, the printed circuit board extended between the battery receiving ribs will not hold the battery. It is possible to load the battery by bringing both poles of the battery into contact with the electrode spring and the electrode terminal plate, which has the advantage of being useful for electrical checks during repair services. Also, when the cabinet body is separated from the cabinet lid, the electrode spring
Each electrode terminal plate is attached to the battery receiving rib, and when batteries are loaded in this state, there is no deformation of the electrode spring or electrode terminal plate, and there is no problem in reconnecting the cabinet body and the cabinet lid. It's something that doesn't exist.
