Abstract

PURPOSE:To make it possible to perform soldering on the captioned battery alike on the other electrical parts by inserting a linear U-shaped terminal, which has flexibility and whose print substrate holding parts are doglegged, into a hole the more narrowing the more approaching both ends provided on the print substrate. CONSTITUTION:The print substrate holding parts 4a of a battery terminal 4 are made to have an angle not exceeding 180 deg. and the shape of a semicircle and an oval so that the battery terminal itself may have self-supporting balance. The width B of the battery terminal hole 5 is made to be smaller than the free length F of the battery terminal 4 so that the battery terminal 4 may continue to hold restoring force due to a spring property even after it is inserted into the battery terminal hole 5. Further, the end shape of the battery terminal hole 5 is so made that the angle not exceeding 180 deg. and the end of a semicircle and a circle may be smaller than the base part. Thereby, the battery terminal can have the self-supporting property thus enabling to perform automatic soldering.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to batteries used in portable electrical products.

Conventional structure and problems Conventionally, to attach a wire battery terminal, as shown in Figure 1, insert the end of the battery terminal 1 into the printed circuit board 2, and press it with your hand or a holding stand to prevent it from coming off. soldering iron 3
Many of them had a structure that required soldering.

However, the above configuration has the problem that only the battery terminals have to be worked in a separate process from other electrical parts, making it difficult to reduce the number of man-hours.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems and is a self-supporting battery terminal device that can be soldered in the same way as other electrical components.

Structure of the Invention The present invention has devised the shapes of the legs of the terminal and the holes of the printed circuit board in order to effectively utilize the elasticity of the battery terminal itself, making it possible to realize a battery terminal made of a wire material that is self-supporting. This makes it possible to automate soldering.

DESCRIPTION OF EMBODIMENTS FIG. 2 shows the shapes of battery terminals and battery terminal holes in a first embodiment of the present invention. In FIG. 2, 4 is a battery terminal and 6 is a battery terminal hole.

The printed circuit board holding portion 4a of the battery terminal 4 has an angle of 180Q or less, or
Make it into a semicircle, oval, etc. shape. The width B of the battery terminal hole 6 is made smaller than the free length F of the battery terminal 4, so that even after the battery terminal 4 is inserted into the battery terminal hole 6, the restoring force due to the spring property is maintained and continuity is obtained. In addition, the end face shape of the battery terminal hole 5 is set to 1 in order to satisfy the principle of restoration as shown in FIG.
Use an angle of 80 degrees or less, or a shape such as a semicircle or ellipse where the end is thinner than the root trunk. In Fig. 3, 40 is the battery terminal 4
5 is the battery terminal hole. FIG. 4 shows the battery terminal of this embodiment inserted into the battery terminal hole. In FIG. 4, 4 is a battery terminal, and 6a is a cross section of a printed circuit board.

Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 6 shows the shapes of battery terminals and battery terminal holes showing a second embodiment of the present invention. In FIG. 6, 7 is a battery terminal, and 8 is a battery terminal hole. The difference from the configuration shown in FIG. 2 is that the spring force of the battery terminal 7 acts to sandwich the printed circuit board as shown in FIG. By providing this, a self-sustaining balance is provided to the battery terminal from the printed circuit board side.

The state is shown in FIG. FIG. 8 shows how the battery terminal of this embodiment is assembled into the battery terminal hole. That is, one side of the battery terminal 7 is fitted into the end, and then the battery terminal 7 is rotated using the end as a fulcrum, so that both sides are fitted as shown in FIG.

As mentioned above, the first. According to the second embodiment, the battery terminals can be self-supporting and can be automatically soldered as shown in FIG. In FIG. 9, 9 is a solder liquid, 4 and 7 are battery terminals, and 6 is a printed circuit board. In other words, according to this embodiment, soldering can be performed in the same process as other electrical components,
Man-hours can be reduced. FIG. 10 is a cross-sectional view when the battery is installed in a product. Note that 10 is a case and 11 is a battery.

Effects of the Invention According to the present invention, automatic soldering can be performed by making battery terminals self-sustaining, thereby achieving excellent cost efficiency and reducing the number of man-hours.
