Claims

[Scope of claim for utility model registration] The connecting portion of the conductor exposed by peeling off the cable insulating layer, the conductor cover attached to the conductor connecting portion, and the diameter adjustment attached to the end of the cable insulating layer. The cable comprises an insulator, and a prefabricated reinforcing insulator having a high voltage shield electrode and attached to the outer periphery of the conductor cover covering part and the diameter matching insulator covering part so that the high voltage shield electrode contacts the conductor cover, At the connection part of a rubber/plastic power cable where the insulation layer, the diameter-matching insulator, and the prefabricated reinforcing insulator are fused together by pressure and heat, the outer periphery of the above-mentioned conductor cover and the diameter-matching insulator covering part. The rubber surface is a tapered surface that is inclined in one direction in the longitudinal direction of the cable connection part, and the inner circumferential surface of the prefabricated reinforcing insulator is a tapered surface that fits with the tapered surface. Plastic power cable connections.
