Description

[Detailed description of the invention] This invention relates to a battery connection device for various electrical devices such as radio receivers and tape recorders, and its purpose is to reduce the number of parts of the device, making it easier to assemble and smaller. The goal is to make it possible.

Conventionally, as shown in FIG. 1, the electrical connection between the battery 3 of the battery storage section 2 provided in the housing 1 of an electrical device and the conductive foil of the printed wiring board 4 was made by connecting the opposite side wall 2a of the battery storage section 2. ,2
Generally, the lead wires 7, 7 are soldered to the compression spring 5 and the terminal piece 6, which are respectively fixed to the terminal b.

However, this type of configuration has major disadvantages in that it requires a large number of parts, is difficult to assemble, and is large in size.

The present invention is intended to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to FIG. 2 and subsequent drawings.

In FIG. 2, reference numeral 11 denotes a cabinet for an electrical device, such as a tape recorder with a radio receiver. It is made up of.

A plurality of bosses 14 are integrally formed on the inner surface of the first cabinet 12, and screws 15 are attached to these bosses 14.
Therefore, the flexible printed wiring board 16 is stretched and fixed.

Electronic components 17 such as resistors, capacitors, and transistors are attached to the flexible printed wiring board 16 to constitute circuits such as a radio receiving circuit and a recording/reproducing amplifying circuit.

Further, as shown in FIG. 3, the conductive foil 18 for circuit formation of the flexible printed wiring board 16 is located on the side opposite to the component mounting surface, and the conductive foil portion 19 for power application, which is a part of the conductive foil 18, is located on the side opposite to the component mounting surface. A part of the flexible printed wiring board 16 is a bent piece 20 that is cut and bent approximately at right angles to the main surface.

21.21 indicates a notch for forming this bent piece 20.

On the other hand, a battery storage section 21 is integrally formed in the second cabinet 13, and one of the opposing side walls 22 forming this storage section 21 has an L facing on both sides thereof.
A letter-shaped guide rib 23.23 is formed.

When the first cabinet 12 is fitted into the second cabinet 13, the bent piece 20 of the flexible printed wiring board 16 on the side of the first cabinet 12 is passed through the through hole 24 of the electrical storage section 2 into the guide rib. 23,2
3, the electrically conductive foil section 19 for applying power provided on the bent piece 20 is brought to a position where it contacts the positive electrode of the right battery 25 housed in the battery housing section 21.

Note that in this embodiment, a compression spring 5 similar to that shown in FIG. For connection, a bent piece as shown in Fig. 3 is used to connect directly.

It goes without saying that the negative electrode side of the battery 26 can also have the same construction as shown in FIGS. 2 to 4, provided that a spring that biases the battery in its longitudinal direction is not used for electrode connection.

Further, in FIG. 2, reference numeral 27 indicates a lid for closing the battery storage section 21. As shown in FIG.

As explained above, according to the battery connection device for electrical equipment of the present invention, the flexible printed wiring board itself is used for connection to the electrodes of the battery, so the number of parts is reduced and assembly is easy, and the electrical equipment can be made smaller, especially thinner. It exerts great power in
