FIG. 1 is a schematic overall structure of an electromagnetic induction heating joining system according to the present invention, in which a synthetic resin molded article 1 to be joined, At 2, the joints 3, 4
Forming a joining projection 3a and a joining groove 4a on the corresponding surface of
A heating element 5 is fitted in the groove 4a, both molded products 1 and 2 are vertically stacked, and the heating coil 6 is put into a receiving jig 7 provided around the heating coil 6, and the receiving jig 7 is pressed by a press platen. 8, the press bed 9 is lowered from above to apply pressure, and at the same time, a high frequency current of the high frequency oscillator 10 is passed through the heating coil 6 to generate a high frequency magnetic flux, thereby directly generating heat in the heating element 5. A part of the joint portions 3 and 4 of the molded products 1 and 2 is melted, and a pressure is applied to the melted resin portion to perform adhesive molding.
【0012】この発明は、前記成型品2の溝4aに発熱

イル状接続線5aとしたことにある。The present invention resides in that the heating element 5 is provided in the groove 4a of the molded product 2 as a coil-shaped connecting wire 5a having a required distance between the wires as shown in FIG.

割成型品を前記説明した如く接合させるものである。When the joint portion of the molded product is annular, the coil-like connecting wire 5a is fitted with the conductive metal connectors 11 at both ends as shown in FIG. 3, as shown in FIGS. Although not shown in the figure, after the metal body is elastically clamped and provided in an annular shape, it is fitted into an annular joining groove of a molded product and the divided molded product is bonded as described above.

コイル状接続線5bを形成してもよいものである。The coil-shaped connecting wire 5a, like the coil-shaped metal body 5b shown in FIG. 6, is obtained by winding a wire having a required wire diameter around a coil having a required diameter to provide a coil spring material. The outer diameter of the tape is formed at the tapered end 5b1 and the other end opposite to the required length is formed at the general cut-off opening end 5b2, and then the taper end 5b1 is screwed and fitted into the general cut-off opening end 5b2. As shown in FIG. 7, an annular coil-shaped connecting wire 5b may be formed.

合用溝4aに嵌入する。Also in this case, as shown in FIG. 1 described above, the coil-shaped connecting wire 5b is fitted into the joining groove 4a formed in the molded product 2. Then, the corresponding molded product 1 is placed on the upper side, and the joining projection 3a is fitted into the joining groove 4a of the molded product 2.

At this time, since the annular coil-shaped connecting wire 5b generates heat, the wall portion and the bottom portion of the joining groove 4a and a part of the joining ridge 3a are melted. Therefore, this molten resin is allowed to enter the inside of the annular coil-shaped metal body 5b, the high frequency is cut off when it is filled, the heat generation is stopped, and the whole of the molded product 1 and the molded product 2 is solidified together. .

げて不向きである。Further, in the conventional connection of a wire or sheet metal to an annular shape, since the connection end is butt-welded, not only the manufacturing process becomes complicated, but also the welded portion spreads out in the form of a dumpling and spreads around the exterior. This makes it difficult to see, especially for joining transparent bodies, because the connecting line is visible from the outside, reducing the commercial value.

る。Further, the conventional wire, sheet metal, etc., once welded, have a constant length and do not change. Therefore, even if the wire is too short or too long, one of the joining grooves will be formed. It has a drawback that it does not close easily, especially if it is bent many times, it may eventually become too long or too short, and it will not fit exactly in the joining groove. However, in this invention, since it is a coil-shaped connecting wire, its length can be adjusted by appropriately expanding or compressing.
