(57) [Abstract] [Purpose] While having a spring member that makes electrical contact with a circuit member in contact with a battery anode and a spring member that makes electrical contact with a watch body in contact with a case of a timepiece, It is to reduce the manufacturing process of the spring member. [Structure] A spring member that is in electrical contact with a circuit member in contact with an anode of a battery and a spring member that is in electrical contact with a watch body in contact with a case of a watch are integrally formed through a battery positive terminal. To do. [Effect] Conventionally, it was necessary to process each spring member, but the processing time of one member can be eliminated and the processing time can be shortened, so that the cost of parts can be reduced.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic timepiece having a battery plus terminal.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 5, a positive conduction spring 1 that contacts the positive electrode of the battery to establish electrical conduction with a circuit member (not shown), and a ground spring 2 that contacts the case of the timepiece to establish electrical conduction with the watch body. Generally, the structure is formed at a position different from that of.

[0003]

[Problems to be solved by the device]

 However, when the plus conduction spring 1 and the earth spring 2 are formed at different positions in a plane, it is necessary to process each spring member, which causes a problem of increasing the manufacturing process of the spring member. Therefore, in order to solve such a conventional problem, an object of the present invention is to provide a spring member which is in contact with a positive electrode of a battery for electrical conduction with a circuit member and a timepiece which is in contact with a case of a watch. It is to reduce the manufacturing process of the spring member while having the spring member that conducts electricity.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention integrates a spring member that makes electrical contact with a circuit member in contact with an anode of a battery and a spring member that makes electrical contact with a watch body in contact with a watch case. Formed.

[0005]

[Action]

 According to the above configuration, the cost of parts can be reduced by eliminating the step of processing one spring member and shortening the processing time.

[0006]

Embodiment An embodiment of the present invention will be described below with reference to the drawings. 1, FIG. 2 and FIG. 3, the battery plus terminal 3 has an elastic arm portion 3a and a tip arm portion 3b, and is fixed to the main plate 4 by using fastening means such as screws. The elastic arm portion 3a elastically contacts the side surface of the battery 5 guided by the main plate 4, and is connected to the circuit block through the battery plus terminal 3 which is in contact with the positive conducting portion of the circuit block (not shown). It is electrically conducting.

The tip arm portion 3b is arranged so as to be bent in the direction of the back cover 6 of the watch case arranged on the side opposite to the base plate 4 from the vicinity of the battery 5 contact portion of the elastic arm portion 3a. By being pressed against 6, the circuit block is electrically connected to the elastic arm portion 3a and the battery positive terminal 3 which is in contact with the positive conduction portion of the circuit block. At this time, the tip arm portion 3b is effective whether it is a rigid body or an elastic body.

In the above structure, the force of the elastic arm portion 3a acting in the direction of the center of the battery 5 is A, the force of the tip arm portion 3b acting in the direction of the back cover 6 is B, and the tip arm portion 3b is If the friction coefficient acting on the contact surface with the back cover 6 is μ, the condition of A> μB is set, so that the elastic arm portion 3a and the battery 5 are always in contact with each other. 2, 3, and 4, the battery positive terminal 3 has the elastic arm portion 3a, the tip arm portion 3b, and a battery holding portion 3c, and is fixed to the main plate 4 by using fastening means such as screws. Has been done. The battery 5 is held and fixed to the battery plus terminal 3 by elastically pressing the side surface of the battery 5 guided by the base plate 4 by the elastic arm portion 3a toward the battery holding portion 3c.

[0009]

[Effect of the device]

 As described above, the present invention, as described above, includes an elastic arm portion that elastically contacts the positive electrode of the battery to establish electrical conduction with the circuit member, and a watch body that contacts the watch case near the battery contact portion of the elastic arm portion. By integrally forming a metal member that electrically conducts with the battery positive terminal, it was necessary to process each member in the past, while eliminating the processing step of one part, Since the processing time can be shortened, the cost of parts can be reduced.

Further, since the battery is held and fixed by the elastic arm portion, it is possible to reduce the number of battery holding members, which contributes to the cost reduction of the timepiece.
