2. Description of the Related Art Conventional contact devices of this type are shown in FIGS. 6 to 10 as examples employed in electromagnetic contactors. In the figure, insulation case 1
A pair of fixed contacts 2a and 2b are attached to the front side of the housing, and each of the fixed contacts 2a and 2b has a fixed contact 3 on the opposite side thereof.
a and 3b are attached, and a terminal (not shown) is extended to the opposite side. A contact support 4, which is guided by the inner wall of the insulating case 1 and is movable in the vertical direction as shown in FIG. 6, is provided between the opposing fixed contacts 2a and 2b. A square hole 4a is provided therethrough along the axis of the square hole 4a, and the other end is connected to an electromagnet having a return spring (not shown). A movable contact 5 is supported through the square hole 4a of the contact support 4,
The spring force of the contact spring 6 and the spring receiver 7 prevent it from falling off. The movable contactor 5 is of a bridge type and consists of contact mounting parts 5a at both ends and a mounting part 5b of the spring receiver 7 in the center, and there is a step between the contact mounting part 5a and the mounting part 5b in which the mounting part 5b is recessed. Contact mounting part 5
Movable contacts 8a, 8 divided into two are disposed at a, facing the fixed contacts 3a and 3b, respectively.
a' and 8b, 8b' are integrated. The spring receiver 7 has a seat plate 7b that fits into the mounting portion 5b of the movable contact 5 and has a protrusion 7a in the center, and a seat plate 7b that is bent from both ends of the seat plate 7b and rises from both outer walls of the square hole 4a of the contact support 4. Leg piece 7c that protrudes and becomes wider
It is made up of. Therefore, the fixed contact 3a,
Movable contacts 8a, 8a', 8b, 8 that come into contact with and separate from 3b
There are multiple contact points with b', so that even if dust or the like adheres to one contact point and causes a contact failure, current can be passed through the other contact point. However, in the contactor device with this configuration, the movable contactor 5
The disadvantage is that the shape is complicated and the material yield is poor, making it expensive. More specifically, in order to improve contact reliability, the movable contacts 8a, 8a', 8b,
The contact attachment portion 5a with which the contact point 8b' is integrated is divided into two parts by the narrow groove 5c, and the movable contact 8b' is divided into two parts by the narrow groove 5c.
a, 8a', 8b, 8b' are bent to increase the length L of the bent portion as a means of increasing the sliding amount of the surfaces of the fixed contacts 3a, 3b. Therefore, the material dimensions required for manufacturing the movable contact 5 are as shown in FIG.
If the width of a is A, the width of the narrow groove 5c is B, and the width of the connecting part in the punching process is C, and the developed length corresponding to the material width is W, then it becomes [(2 x A) + B + C] x W, and the material yield is extremely high. To make matters worse, material costs accounted for an extremely large portion of the unit price of parts, making it impossible to absorb them through cost reductions from processing alone. Furthermore, the width D1 of the fixed contacts 3a, 3b is also the same as that of the movable contacts 8a, 8a', 8.
Since it is necessary to make the width slightly larger than the width (2×A)+B of b, 8b', there is also a drawback that it becomes expensive.

1 to 5 are diagrams showing an embodiment of the contactor device according to the present invention. In the figures, the same parts as those of the conventional device shown in FIG. 6 described above are given the same reference numerals, and differences will be explained. do. The difference between this embodiment and the conventional device is that first, the movable contactor 15 is divided into two parts, each of which is shaped like an unbent band, and one part is assembled by rotating it by 180 degrees. The movable contactor 15, which is a molded product made of synthetic resin, is divided into two parts and has the function of integrating the movable contactor 15 and ensuring the deflection length L. To explain in detail with the drawings, each part of the movable contactor 15 is formed into a strip having the same width as a whole, with the center part being displaced from both ends by a distance F toward one side on the same plane, as shown in FIG. This is formed by progressive punching from a strip plate using a press or the like, and has a protrusion 15a in the center, and movable contacts 8 at both ends.
a and 8b are fixed. The amount of displacement F of the movable contact 15 must be selected so that when the two strips are rotated 180 degrees and combined, a gap E1 is created between them. On the other hand, the spring receiver 17 is formed in a gate shape, and has a protrusion 17b in the upper center of the top side 17a for guiding one end of the contact spring 6, and a recess 17c in the lower center into which the protrusion 15a of the movable contact 15 is fitted. A protruding seat 17d is provided, respectively. Furthermore, a leg piece 17f having a narrow neck 17e located on the axis is extended on each of the longitudinally opposing sides of the top side 17a, and it is possible to sandwich both side walls from inside the square hole 4a of the contact support 4. It's getting old. In the above component configuration, the square hole 4 of the contact support 4
To assemble the movable contact 15 into the spring receiver 17, the movable contact 15 is inserted into the spring receiver 17 by pushing each of the divided movable contacts 15 between the necks 17e of the spring receiver 17 from both sides and engaging the protrusions 15a with the recesses 17c of the protrusion 17d. Unify through. Thereafter, the integrated movable contact 15 and the spring receiver 17 are inserted through the square hole 4a, and the contact spring 6 is attached and fixed at a position where the leg piece 17f straddles the square hole 4a. In the above configuration, the movable contact 15 can be formed by simply cutting the material and feeding it sequentially, so it can be manufactured almost by a scrap press. Therefore, the material yield is greatly improved, and the spring receiver 17
Since the movable contact 15 is pressed by the protruding seat 17d provided in the movable contact 15, the length L of the bent portion can be secured without bending the movable contact 15.
The material width W1 can be made narrower, and the weight of the material that occupies the movable contactor 15 in total can be significantly reduced. In addition, since the movable contacts 15 are configured by rotating the same-shaped contacts by 180 degrees and combining them, the contact point becomes tapered, and the width D2 of the fixed contacts 3a and 3b can be adjusted accordingly without affecting the current carrying performance at all. It also has the advantage of being narrower and cheaper.

[Effects of the Invention] According to the present invention, the movable contactor is divided into two strips, and the two divided strips are supported by a spring receiver and integrated.
The cost of materials that make up the movable contact is significantly reduced,
An inexpensive contact device can be provided without deteriorating current carrying performance or increasing the size.
