おそれがあつた。 However, in order to configure the stress cone,
When a medium-width or large reinforcing oil-impregnated paper is laminated and rolled directly onto the cable insulator, the reinforcing oil-impregnated paper easily slides on the insulator because the outer peripheral surface of the cable insulator is smooth. It was not possible to tighten it sufficiently. In this case, there was a risk that the stress cone would be thermally deformed during energization and the dielectric breakdown strength would decrease.

とを特徴とするものである。(Means for solving the problem) That is, the cable connection part of the present invention is a cable connection part equipped with a stress cone formed by wrapping reinforcing oil-impregnated paper on the insulator of a rubber or plastic insulated cable. A stress cone is constructed by wrapping a narrow width of oil-impregnated paper on an insulator and rolling a reinforcing oil-impregnated paper with its winding start end sandwiched within the winding end of said narrow-width oil-impregnated paper. This is a characteristic feature.
（実施例） 以下、実施例に基づき本考案を説明する。(Example) The present invention will be explained below based on examples.

の遮蔽体６が設けられている。 In these figures, a stress cone 2 is provided by wrapping reinforcing oil-impregnated paper on the cable insulator 1 exposed by peeling off the cable end, and a bell mouth shield 3 is attached to the outside of the stress cone 2. There is. A shield 6 such as a metal tape or braid is provided along the tapered surface of the stress cone 2 between the bell mouth shield 3 and the cable's external semiconductive layer 4 or cable shield layer 5 .

うにコーン状になるようにされている。 Thus, the stress cone 2 is made by first wrapping a narrow width oil-impregnated paper 7 on the cable insulator 1 in a tight wrap, and then wrapping a medium-width or large-width reinforcing oil-impregnated paper 8 around the winding start end 8a. It is constructed by inserting it into the winding end portion 7a of the narrow oil-impregnated paper 7 and rolling it. Note that the reinforcing oil-impregnated paper 8 is cut in advance into a tapered shape in the length direction, so that when it is wrapped around the insulator, it becomes a cone shape as shown in the figure.

レスコーンの熱変形が解消できる。(Effects of the invention) As described above, in the cable connection part of the invention, a narrow width of oil-impregnated paper is provided on the cable insulator by wrap-wrapping that can be tightened, and reinforcing oil-impregnated paper is placed inside the end of the winding at the beginning of the winding. Since the stress cone is constructed by sandwiching and rolling the stress cone, the reinforcing oil-impregnated paper can be sufficiently tightened when forming the stress cone, preventing thermal deformation of the stress cone during energization. It can be resolved.
