Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for fixing a conductive metal plate to an insulating member, for example, for fixing a bus bar to a synthetic resin substrate.

[Prior Art] In electrical circuits and the like, it is often necessary to fix a conductive metal plate such as a bus bar on a synthetic resin substrate that is an insulating material. Conventionally, a hole is made in either a conductive metal plate or a synthetic resin plate, and a protrusion that fits into the hole is provided in the other, for example, as shown in FIG. Although it has been practiced to fit the protrusion 4 of the synthetic resin substrate 3 into the hole, this fitting method has the disadvantage that it is easy to come off.

Further, as shown in FIG. 3, a long protrusion 4 protruding from the synthetic resin substrate 3 is inserted into the hole 2 drilled in the conductive metal plate 1, and the tip of the protrusion 4 is melted on the conductive metal plate 1 side. In addition, a bulge 5 is formed at the tip to prevent the protrusion 4 from coming out of the hole 2. However, in this case, only the melted bulge portion 5 increases in thickness as a whole, which causes problems when laminating these parts.

Furthermore, as shown in FIG. 4, the synthetic resin substrate 3 may be provided with claws 6, and the conductive metal plate 1 may be locked by the claws 6. In this case, too, the claws 6 protrude and the overall thickness is reduced. The disadvantage is that it becomes large.

[Purpose of the invention] The purpose of the invention is to provide a structure for fixing a conductive metal plate to an insulating member, which does not bulge outward as in the conventional example described above and can achieve a reliable connection. be.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
When a conductive metal plate is embedded and fixed in an insulating member made of synthetic resin, a claw portion is provided at a height flush with the surface of the insulating member toward a housing portion of the insulating member that accommodates the conductive metal plate. This is a structure for fixing a conductive metal plate to an insulating member, characterized in that a concave portion is formed in a side portion of the conductive metal plate, and the claw portion is locked in the concave portion.

[Embodiment of the invention] The invention will be explained in detail based on the embodiment shown in FIG.

FIG. 1 shows a case where a bus bar 10 made of a conductive metal plate is buried and fixed in a synthetic resin substrate 13 which is an insulating member.
The edge portion 15 of the buzz bar 10
Recesses 16 are provided at several locations. A plurality of claw portions 17 are provided on the synthetic resin substrate 13 at a height flush with the surface thereof and protrude toward the housing portion. The claw portion 17 is engaged with the recess 16 of the buzz bar 10.

By doing so, the claw portions 17 do not protrude above the surface of the synthetic resin substrate 13, and the bus bar 10 can be fixed to the synthetic resin substrate 13 with a reduced thickness.

[Effect of the invention] As explained above, according to the structure for fixing the conductive metal plate to the insulating member according to the present invention, when the conductive metal plate is fixed to the insulating member, a part of the insulating member protrudes outward. This has the advantage that there is no problem and reliable connection is possible.
