It is characterized in that it is bent inside and the inclined terminal and the free end of the contact spring are overlapped in the plate thickness direction of the terminal. [Operation] According to the present invention, the terminal on which the free end of the contact spring is finally overlapped is provided so as to be inclined when punching from the metal plate for a terminal, so that the contact spring is fixed from the metal plate for a terminal. It can be performed immediately after punching without disturbing other terminals. [Embodiment] The present invention will be described in detail below with reference to the illustrated embodiment. In the present invention, as the terminal member 9, as shown in Fig. 2 (a), a punched metal plate for a terminal is used. However, at the time of this punching, of the terminals 2a, 2b, 2c, a pair of terminals 2a, 2b, which will be fixed contact terminals and are finally stacked at intervals in the plate thickness direction, will be terminals that will be common contact terminals. It is assumed that it is not parallel to 2c but tilted in the plane of the plate.
Further, in keeping one end of each terminal 2a, 2b, 2c connected to each other by the connecting piece 1, between the connecting piece 1 and the inclined terminals 2a, 2b, the neck portion 7 having a narrow width, I will leave it as 7. Also, for the terminal 2c immediately after punching,
The contact spring 10 is fixed by welding or caulking. Terminal
Since 2a and 2b are inclined as described above, the contact spring 10
Both terminals 2a and 2b do not get in the way when they are fixed.
Further, since the terminals 2a, 2b, 2c are still connected to the connection piece 1 and are parallel to each other in the plate surface, it is easy to hold and fix the terminal 2c to which the contact spring 10 is fixed. And it can be performed reliably. Next, the terminals 2a, 2 of the terminal member 9 punched out as described above
b, that is, the terminals 2a and 2b that are inclined with respect to the longitudinal direction of the connection piece 1 and the other terminals 2c are subjected to Z-shaped bending in the plate thickness direction by press working, and the tips of both terminals 2a and 2b are fixed. The terminals 2a, 2b are displaced from the neck portions 7, 7 in the plate surface of the terminal member 9 by displacing the terminals 2a, 2b in the opposite direction in the plate thickness direction and further as shown in FIG. 2 (b). Of the contact springs are overlapped with each other in the plate thickness direction with a gap between them.
The free end of is located between the terminals 2a, 2b. Then, for each terminal 2a, 2b, 2c, the base 8 shown in FIG.
Then, the terminals 2a, 2b, 2c are inserted into the base 8 and then the connecting piece 1 is cut off to make the terminals 2a, 2b, 2c independent. On the lower surface side of the base 8, the terminals 2a, 2b, 2c are arranged in a line, and on the upper surface side of the base 8, the terminals 2a, 2b overlap in the plate thickness direction and the free ends of the contact springs 10 are located between them.
It can be obtained from a single terminal member 9. Moreover, not only a separate terminal material is not required, but the terminals that are inclined with respect to the longitudinal direction of the connection piece 1 when punching out from the metal plate for terminals are stacked at intervals in the plate thickness direction.
2a and 2b are provided and they are stacked by bending the base ends of them, and the space between the terminals on both sides is effectively used as the space for forming the terminals 2a and 2b in a tilted state. Therefore, the material loss of the metal plate for terminals is the same as that when the terminals 2a and 2b do not overlap in the plate thickness direction. FIG. 3 to FIG. 5 show an example of the form of bending performed by press working so that the terminals 2 are spaced in the plate thickness direction. One of the pair of terminals 2a and 2b, which are overlapped with each other in the plate thickness direction with an interval, may be bent at the same time as shown in each figure (a), and at the same time, the other may be bent as shown in each figure (b). 6 to 9 show examples of the shapes of the pair of terminals 2a and 2b which are overlapped with each other in the plate thickness direction with a gap therebetween. The inclination in the plate surface at the time of punching out the terminals 2a, 2b is not limited to that shown in FIG. 2, and the terminal 2a should be in the left direction in the drawing and the terminal 2b should be in the right direction in the drawing. Good. Both terminals
As shown in FIG. 2, when the inclinations of 2a and 2b are in the same direction, the inclination angles α 1 and α 2 are the same as the angle α 2 of the terminal 2b on the side close to the terminal 2c to which the contact spring 10 is fixed. Is the terminal
It should be smaller than the angle α 1 of 2a.

を得られるものである。As described above, in the present invention, the tilted terminal is bent in the plate thickness direction, and the base end of the connection piece side is bent in the plate surface, so that the tilted terminal and the contact spring fixed to another terminal are free. Since the end and the terminal overlap in the plate thickness direction,
The process of fixing the contact spring to the other terminal, which is finally overlapped with the terminal in the plate thickness direction, is performed immediately after punching when all terminals are still connected to one side edge of the connection piece and are in a flat plate state not bent. Therefore, the contact spring can be fixed without being disturbed by other terminals, and the terminal can be easily and surely held at this time. The stabilization of is obtained.
