られないという欠点があった。However, in such conventional mold molding method, when the conductor connection part of the cable is inserted into the mold, the cable is fixed by the couple insulator gripping parts at both ends of the mold. Therefore, when the heated and molten polyolefin composition is press-fitted, the set conductor connection part and the cable insulation following it are transferred by OJ, resulting in uneven thickness in the formed mold, and the insulator connection part with good characteristics is lost. The disadvantage was that it was not possible to obtain

を固化させ、しかる後二つ割り金型を開放する。After the mold 1 is fitted around the outer periphery of the conductor connection part in this way, the melted crosslinkable polyolefin composition is poured into the resin press-fit hole 7 provided in the mold 1: 1-Yavity 2
Press it inside. In addition to the polyolefin composition containing a crosslinking agent, a silyl-modified polyolefin composition capable of water crosslinking may be used as the above composition. At this time,
Since the spacer is formed from a cross-linked polyester material, it will not melt at the human temperature of the composition, and the movement of the connecting portion 2 can be suppressed. In addition, since the material is the same as the press-fitted composition, the two are completely integrated and have good electrical properties.In this way, the heated molten resin is completely filled into the cavity. After that, the mold is allowed to cool to solidify the composition in the cavity 2, and then the two-split mold is opened.
