Description

[Detailed Description of the Invention] The present invention relates to a battery storage device for electrical equipment such as radio receivers and transceivers.

Generally, battery storage devices use electrode terminals to connect the batteries to each other, and the electrode terminals are soldered to the conductor layer of a printed wiring board with lead wires, or to pins fixed on the printed wiring board. Was. However, since the electrode terminals are connected to the printed wiring board with lead wires, there is a problem in that the wiring process becomes troublesome. In order to simplify the processing of such lead wiring, it is conceivable to attach the electrode terminals directly to the printed wiring board, but in this case, there is a problem that attachment of the electrode terminals to the battery case becomes troublesome. In other words, since the battery case is installed on either the main body side or the lid side of the electrical equipment cabinet and is configured in a combined state, there is a problem that it becomes difficult to attach the electrode terminals attached to the printed wiring board to the battery case. It was hot.

The present invention solves these conventional drawbacks by forming a battery case separately from the cabinet, and using electrode terminals to hold the battery case on the printed wiring board. This is a feature. The battery storage device of the present invention will be described below with reference to drawings of embodiments.

1, 2, and 3 show an example of the configuration of the battery storage device of the present invention. In the figures, 1 is a synthetic resin cabinet body constituting a radio receiver, and 2 is the inside of the cabinet body 1. 4 is a synthetic resin battery case attached to the printed wiring board 2, which is constructed separately from the main body of the cabinet. has been done. 5 is a coil-shaped electrode terminal fitted into the fitting groove 4a at the end of the battery case 4, and 6 is the fitting groove 4 at the end of the battery case 4.
It is a flat electrode terminal fitted into b. Here, the printed wiring board 2 has conductor layers 7a, to which electrode terminals 5, 6 are connected, as shown in FIG.
A conductor layer 7c to which only the electrode terminal 7b and the electrode terminal 5 are connected, and a conductor layer 7d to which only the electrode terminal 6 is connected are provided. Six mounting holes 8a to 8f are provided. The electrode terminals 5 and 6 are inserted into the mounting holes 8a to 8f of the printed wiring board 2 while being fitted into the fitting grooves 4a and 4b of the battery case 4, together with other electrical components (not shown). It is soldered and fixed with solder 9. Therefore, the three batteries 1 housed in the battery case 4
0 are connected in series, and the series voltage is taken out between conductor layers 7c and 7d. Further, the other end of the electrode terminal 6 has a fitting portion 6a, which is engaged with the upper end of the battery case 4. Therefore, the battery case 4 is attached to the printed wiring board 2 through the electrode terminals 6.

The electrode terminal 5 is brought into contact with the negative electrode of the battery 10, and the electrode terminal 6 is brought into contact with the positive electrode of the battery 10, and a cabinet lid (not shown) is integrated into the cabinet body 1. Needless to say, the battery 10 is housed between the battery case 4 and the battery case 4.

As described above, according to the present invention, the electrode terminals are fitted into the battery case separate from the cabinet and attached directly to the printed wiring board, so there is no need to wire the lead wires. In addition, since the battery case can be held on the printed wiring board with electrode terminals formed separately from the cabinet, the electrode terminals can be attached to the fitting grooves of the battery case when the cabinets are assembled. The battery case itself does not need to be inserted into the battery, and its assembly is extremely easy, and the battery case itself can be configured to be airtight, which is advantageous in terms of measures against leakage. Furthermore, the battery case is formed so that a plurality of batteries are arranged side by side, and flat electrode terminals are located at either end facing each other, and a number connecting part provided at the tip of the flat electrode terminal is provided. Since they are engaged with the upper end of the battery case, their practical value is extremely great, as the battery case can be securely mounted on the printed wiring board by means of these flat electrode terminals.
