The second U-shaped protruding wall 9b is provided with a pair of engagement grooves 11 for mounting the second battery spring 15, and a contact rib 16 for preventing the second battery spring 15 from coming off. and a claw 17. Further, the second U-shaped protruding wall 9b is provided with a convex rib 18 that serves as a pillow for the wire portion 14 of the first battery spring 10. 2nd above
In the battery spring 15, the connection part 27 of the battery spring 15 is located on the boss 19 provided in the cabinet body 8, solder is applied to the foil of the printed circuit board 20, and the printed circuit board 20 is attached to the boss 19 with screws 21. Connected by tightening and fixing. The first battery spring 10 and the second battery spring 15 are such that the wire portion 14 of the first battery spring 10 having a U-shaped straight portion is located on the convex rib 18, and The outermost coil portion 22 of the spring 15 comes into contact with the engagement groove 11 of the second U-shaped protruding wall 9b by fitting thereinto.

The assembly operation of the battery spring mounting device constructed as above will be described below with reference to FIGS. 2 and 3.

First, FIG. 2 is a top view, and on the convex rib 18 provided on the second U-shaped protruding wall 9b is a straight wire rod portion of the first battery spring 10 attached to the first U-shaped protruding wall 9a. Say 14. In this state, the second
The outermost coiled part 22 of the battery spring 15 is the second
By fitting into the pair of engagement grooves 11 of the U-shaped protruding wall 9b, the linear wire portion 14 of the first battery spring 10 is connected to the convex rib 18 and the second battery spring 1.
The linear wire portion 14 of the first battery spring 10 is located inside the coiled portion 22 of the first battery spring 10.
8 as a fulcrum and comes into contact with the coiled part 22 of the second battery spring 15, and the spring load of the second battery spring 15 is constantly applied to the straight wire part 1.
The battery springs 10 and 15 are connected in a two-point contact manner, with the load always moving to two points 23 and 24, which are trying to contact the two battery springs 10 and 15. Above convex rib 1
The height of 8 is determined by the wire diameter of the battery spring 10 and the convex rib 18.
The sum of the heights is the engagement groove 1 of the second U-shaped protruding wall 9b.
1 and the wire diameter of the battery spring 15. As shown in Figure 4, battery 2
5 is inserted and stored, a spring load is applied to the battery spring 15 in the direction A, and the two battery springs 1
Stable contact can be obtained by applying a larger load to the contact points 23 and 24 of 0 and 15.

In this embodiment, the - pole of the battery 26 and the - pole of the battery 25 are combined, and the circuit of the battery 26 and the circuit of the battery 25 are different.

Effects of the Invention As described above, the present invention has first and second U-shaped protruding walls adjacent to each other provided in the cabinet, and the first battery spring attached to the first U-shaped protruding wall has a second battery spring mounted on the first U-shaped protruding wall. The second U-shaped protruding wall is provided with a linear wire portion extending from the U-shaped protruding wall, and the second U-shaped protruding wall is provided with a convex rib that serves as a pillow for the wire portion of the first battery spring. When the second battery spring is attached to the letter-shaped protruding wall, the coiled part of the second battery spring comes into contact with the straight wire part of the first battery spring, applying spring pressure, and the two-point contact stabilizes the battery spring. It is possible to achieve electrical conduction. As a result, the number of parts can be reduced to two, and the screws can also be used as screws for mounting the board, reducing the number of parts and the number of work steps.
