Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an enlarged schematic cross-sectional view showing a basic structure of a mounting structure for mounting a mounting member to a mounted member according to the present invention. In FIG. 1 (a), a protruding portion 111 (a state indicated by a dotted line before thermal caulking) made of a molded resin and protruding from an electronic component mounting member (hereinafter referred to as "first case") 100 is made of a metal plate. An opening 409 provided in the clamping member (hereinafter referred to as “support plate”) 400 and an opening 251 provided in a mounting member (hereinafter referred to as “second case”) 250 made of molded resin for electronic components, The front end of the protrusion 111 is inserted with the surface of the second case 250 inclined by a predetermined angle θ1 from a position perpendicular to the protrusion direction of the protrusion 111 and protruding through the second case 250. A configuration is disclosed in which a heat crushing receiving surface (hereinafter referred to as “heat caulking receiving surface”) 257 is provided around the opening 251 from which the protruding portion 111 protrudes while being fixed by being crushed by heat. Has been Here, the heat caulking receiving surface 257 is formed of a plane perpendicular to the projecting direction of the projecting portion 111 (may be substantially perpendicular). A support plate 400 is disposed between the first case 100 and the second case 250, and the support plate 400 is sandwiched between the first case 100 and the second case 250 and fixed integrally therewith. At this time, an opening 409 is provided in the support plate 400, and the protrusion 111 of the first case 100 passes through the opening 409. Then, as shown in FIG. 1 (a), the protruding portion 111 of the first case 100 is inserted into the opening 409 of the support plate 400 and the opening 251 of the second case 250, and the tips thereof are crushed by heat caulking, thereby Each member is fixed integrally. This thermal caulking is performed by pressing the heated punch from directly above the projecting portion 111 to the tip of the projecting portion 111 as indicated by an arrow. At this time, the heat caulking receiving surface 257 from which the projecting portion 111 projects is projected. Since the surface is perpendicular to the protruding direction of the portion 111, the tip of the crushed protruding portion 111 does not become distorted, that is, the crushed portion of the protruding portion 111 is uniformly along the surface of the receiving surface 257 for heat caulking. The heat caulking receiving surface 257 is in close contact with and spreads and can be easily, surely and firmly attached by heat caulking.

  By the way, in the basic configuration, the support plate 400 is sandwiched between the first case 100 and the second case 250. This is for fixing the first case 100 and the second case 250 to the support plate 400 at the same time. Accordingly, in some cases, the support plate 400 may be omitted, and the first case 100 and the second case 250 may be directly fixed as shown in FIG. Also in this case, as in the case of FIG. 1A, the tip of the crushed protrusion 111 does not become distorted, and attachment by thermal caulking can be performed easily, reliably and firmly.

  In FIGS. 1A and 1B, the shape of the opening 251 provided in the second case 250 widens toward the first case 100 and extends from the protrusion 111 (the heat of the opening 251). The shape is such that a large gap is generated in a portion other than the caulking receiving surface 257. More specifically, in the cross section shown in FIGS. 1A and 1B, one side is a straight line parallel to the protruding direction of the protruding portion 111, and the other side is on the surface of the second case 250. It is a vertical straight line. The reason why the opening 251 has such a shape is as follows. That is, when the second case 250 is made of molding resin, a pair of molds for molding the second case 250 may need to be joined in a direction perpendicular to the surface of the second case 250 and separated. 2 (the second case 250 shown in FIG. 2 described below is provided with a storage portion 253 and its inner peripheral side faces a direction perpendicular to the surface of the second case 250. It is necessary to join and pull away in a direction perpendicular to the surface of the case 250). Therefore, in this case, when the opening 251 is formed in consideration of the moving direction of the mold, the shape becomes the above-mentioned divergent shape (the inner peripheral surface shape of the opening 251 is changed to a cylindrical shape parallel to the protruding direction of the protruding portion 111. If a mold is used, the mold cannot be pulled up and down after molding.)
