The battery receiving spring in a quartz watch is one of the parts that plays the role of establishing electrical continuity between the battery that is the driving source of the watch, the electronic components that are the driving mechanism, or the circuit board on which they are mounted, and its function is very important. is important. For this reason, various types of battery receiving springs have been considered up to now, but they have many drawbacks in terms of ease of assembly, electrical conductivity, etc. Figure 1 shows the assembly structure of a watch battery receiving spring according to the prior art.
A is a plan view thereof, and B is a sectional view of A. In FIG. 1, 1 is a base plate, 2 is a battery receiving spring, 3 is a circuit board, 4 is a screw, and 5 is a battery indicated by a chain double-dashed line. The battery receiving spring 2 and the circuit board 3 are stacked,
Further, a pattern (not shown) of the circuit board 3 is electrically connected to the battery receiving spring 2 and fixed onto the base plate 1 with screws 4. However, in such a structure, the base plate 1 is
It has a structure in which the battery receiving spring 2 and the circuit board 3 are stacked on top, and the thickness near the screw 4 part is thicker, and it is applicable when there are restrictions on the thickness of the finished product or spatial restrictions in the thickness direction. Can not do it. In addition, screws are often standardized for the purpose of reducing the number of parts and improving ease of assembly, and the length of the part where the thread exists is determined, so when it comes to a laminated structure, the thread There were many drawbacks, such as the length of the part where the screw engaged with the base plate became shorter, making the tightening force unstable and preventing the screw from fully demonstrating its original function.

It is an A sectional view. 20 is a battery receiving spring, 21 is a battery contact portion of the battery receiving spring 20, and 22 is a battery receiving spring 20.
The circuit board contact portion 30 is a circuit board, and the other numbers are the same as in FIG. In this structure, a circuit board contact part 22 is newly provided on the battery receiving spring 20, and the circuit board contact part 22 is extended to a pattern part (not shown) on the upper surface of the circuit board 30. By providing electrical continuity, a laminated structure near the screw 4 is avoided. The structure of the battery receiving spring 20 is such that a downwardly downward part is formed from the screwed part into the battery storage hole, and the battery contact part 21 is slightly raised or lowered, so that when the battery 5 is stored, it has a spring property. 5. The circuit board contact portion 22 is located on the opposite side of the battery contact portion 21 from a straight line that passes through the center of the screw 4 and is approximately perpendicular to the straight line connecting the screw center and the battery contact portion 21 .

If an upward floating force such as this occurs, and the tightening force of the screw 4 is weak, or if the screw 4 loosens due to external vibration or impact, the force acts in the direction of weakening the contact with the circuit board 30. Therefore, it also has the disadvantage that electrical continuity becomes unstable.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows an assembled structure of a battery receiving spring according to the present invention, where A is a plan view thereof and B is a sectional view taken along line A-A of A. 40 is a battery receiving spring made of a conductive material;
41 is a battery contact portion of the battery receiving spring 40, which is electrically connected to one pole of the battery 5; 42 is a circuit board contacting portion of the battery receiving spring 40. Other numbers are the same as in Figures 1 and 2. The structure of the battery receiving spring 40 is exactly the same as the battery receiving spring 20 shown in FIG. A hanging part is formed from the tightening part along the battery storage hole, and a battery contact part 41 is formed in the part from the hanging part to the battery contact part 41 as shown in FIG. 3B.
A receiving spring portion is formed that applies a bending force in the direction. Further, the circuit board contact part 42 is composed of a circuit contact part for contacting the circuit board 30 with a pattern (not shown) to establish electrical continuity, and a pressing member having spring properties that connects the circuit contact part and the screw tightening part. The circuit contact part is a perpendicular line drawn from the circuit contact part to the straight line passing through the center of the screw 4 that fixes the battery receiving spring 40 and connecting the center of the screw and the battery contact part 41. It is located on the 41 side.
According to this structure, since the circuit board contact portion 42 of the battery receiving spring 40 is provided below the screw 4 in FIG. 3A, the force generated when the battery 5 is assembled as shown in FIG. 3B. Due to P, a downward force W 2 is applied to the circuit board contact portion 42 of the battery receiving spring 40 by the spring force of the pressing spring in the same direction as the bending direction of the receiving spring, as shown in the figure, due to the reaction force of the receiving spring, and the circuit The contact pressure with the substrate 30 is strengthened, and electrical continuity becomes stable. Further, even if the screws 4 are loosened due to external vibrations or shocks, the contact pressure of the circuit board contact portion 42 with the pattern of the circuit board 30 is increased, and electrical continuity becomes more stable. Therefore, it is possible to obtain a stable function as a battery receiving spring having a contact portion with a circuit board.
