か二箇所支持できぬ悩みがあつた。 In this type of structure, the holder with the contact plate attached is attached to the case facing the direction in which the covers join together, and a part of the case has a depth in the direction in which the covers join together. There is a device in which a groove is provided and a part of the contact plate is attached to the bottom of the groove facing in the joining direction (see, for example, Japanese Utility Model Application Publication No. 49-1864). This type of structure has the problem that when multiple contact plates are arranged one above the other, the upper contact plate is located in the middle of the groove, so only the lowest one can be supported in two places. .

Since the structure of the support body 13 is simply that a through hole 14 for passing through the contact plate is formed in the plate body, the structure is simple and has the great advantage of being easy to manufacture. This means that the material appearing on the surface of the case is required to have heat resistance and nonflammability in addition to insulation. Although a material with poor workability is selected due to safety standards, in the present invention the movement of the contact plate 8 in the longitudinal direction is prevented by the first support 7, and the second
It is sufficient to form the support 13 by just drilling holes, and there is a practical advantage that even materials with poor workability can be processed with high workability.

ある。 Moreover, in the above case, a plurality of through holes 1 are arranged vertically and horizontally in a three-dimensional manner corresponding to the arrangement of the plurality of contact plates 8.
4 to the case 1 in a direction (longitudinal direction of the contact plate 8 in the attached state) that intersects the direction in which the first support 7 and the cover 15 are assembled to the case 1. By simply adding the step of inserting the cover into the mounting part 12 provided after the first step, the holding groove 16 provided in the cover 15 can be inserted into the second step during the second step (attachment of the cover). It is possible to complete the fixation of the second support body 13 to the case 1 by inserting it into the support body 13, and in addition, all of the plurality of contact plates 8 arranged vertically and horizontally are connected to the first support body 7. It has the advantage that all the contact plates 8 can be stably supported by being supported at two points by the second support member 13, which has been completely fixed as shown in FIG.
