のであつた。 Generally, as a power supply contact spring for a battery-powered watch, a battery receiving spring is used on the bottom surface of the battery on the back side of the watch to make an electrical connection between the negative terminal and the circuit board pattern electrode (hereinafter referred to as the pattern), and a battery receiving spring is placed on the top surface of the battery. A presser spring is used to secure the battery and make an electrical connection between the positive electrode and the pattern. The battery receiving spring and battery holding spring ensure continuity with the pattern.
In order to securely hold the battery, it is necessary to fix it to a circuit board or the like by screwing, soldering, or the like, which has the drawback of increasing the number of parts and assembly man-hours.

Reference numeral 2a denotes a battery storage section provided in the device cover 2 and into which the battery 1 is placed. Although the circuit board 3 is held down by the device cover 2, since there is a space into which the battery storage section 2a can be dropped, the circuit board 3 and the battery storage section 2a do not overlap in cross section.

The hook 4a is used to fix the battery holding spring 4 to the device cover 2, and its cross section is shown in FIGS. 3 and 4. In order to hang the hook 4a, a through hole 2b is provided on the outer periphery of the battery accommodating portion 2a, and a hook receiving portion 2c is provided on the inner surface of the through hole 2b on the side of the battery accommodating portion. As shown in FIG. 4, one of the two hook receiving parts is provided with a slope 2f to make it easier to hang the hook 4a, but of course both may be provided with a slope 2f.

Further, the pattern contact portion 4b that is brought into contact with the pattern has spring properties and is connected through the through hole 2e of the device cover 2.

大な効果を有するものである。 As described in detail above, according to the battery holding spring mounting structure of the present invention, when fixing the battery holding spring, there is no need to use any secondary members such as screw tightening or soldering, to ensure a secure connection. In addition, by not using the above-mentioned parts, the space that was considered troublesome until now can be removed, the watch can be made smaller, and the hook structure makes it easy to assemble, and the number of parts and man-hours are reduced. This has great practical effects, such as the ability to significantly reduce costs.
