ルの接続部のモールド方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method of molding a connection portion of a rubber/plastic insulated cable such as a cross-linked polyethylene insulated cable (hereinafter referred to as "C" cable).

。[Technical Background of the Invention] Generally, when forming an insulation reinforcing body at the connection part of a rubber/plastic insulated cable such as a CV cable, an uncrosslinked rubber compound containing a crosslinking agent is used on the conductor connection part.
A method is used in which a plastic tape is wound, the wound layers are fused together by heating, and then crosslinked.

れている。Therefore, as a heating means for the rubber/plastic tape wound layer used in such a method of molding a connection part insulator, a method that uses a far-infrared heater (hereinafter referred to as an IR heater) in combination with a high-frequency induction coil has conventionally been used. It has been known.

ている。In this method, as illustrated in FIG. An upper heater is disposed, and the wound layer is heated from the outside by heat radiation from this heater, and high-frequency induction coils 6.6' are placed outside the cable insulators 5.5' on both sides of the IR heater 4. The pull conductor 7.7' is heated by induction, whereby the heat of the rubber/plastic tape wound layer 3 is transferred to the cable conductor 7.7'.
A method is adopted to prevent the leakage from escaping to the outside through 7'.

温度に達するのに長時間を要するという問題があった。[Problems with the Background Art] However, in such conventional heating methods, the heat for heating and molding the rubber/plastic tape wound layer 3 is mainly emitted from the IR heater, and this heat is transferred to the wound layer 3. As the entire layer is heated by conduction inside the layer 3,
There was a problem in that it took a long time for the temperature of the wound layer 3 immediately above the conductor connection sleeve 2 to reach a predetermined temperature.

加熱手段の熱効率が低いという問題があった。In addition, especially when the conductor size is large, a large amount of heat escapes to the outside through the cable conductor 7.7', and this can also be suppressed by induction heating of the cable conductor 7.7' by the high frequency induction coil 6.6'. Because it cannot be adequately prevented,
There was a problem that the thermal efficiency of the heating means was low.

In the method of fusing together and then crosslinking, a metal strip is placed along the outer periphery of the wound layer of the rubber/plastic tape, and a high-frequency induction coil is placed around the outer periphery of the conductor connection sleeve outside the metal strip. The method is characterized in that the metal strip and the conductor connection sleeve are both inductively heated, thereby heating the wound layer.
