この発明はゴム、プラスチツクケーブルの接続
方法に関し、特に高周波誘導加熱により、接続部
絶縁体をモールドする工程に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of connecting rubber or plastic cables, and particularly to a process of molding a connection insulator by high-frequency induction heating.
背景と目的

A metal support layer 18 is provided on the outside thereof. This is for supporting the metal body 19 in an appropriate position. In addition, the material for the connection part insulator 16 may be silicone rubber, for example.

えばほぼ等しくなる）ようにしておく。 The metal body 19 has a cylindrical shape concentric with the cable conductor 10. Its role is twofold. One is that the cable conductor 10 and the connecting portion insulator 16 are heated from the outside by high-frequency induction heating. Another purpose is to serve as a monitor that directly measures the temperature of the cable conductor 10. That is, a temperature detection sensor 20 is attached thereto and connected to an external indicator 21. As the metal body 19, a braided wire of copper or iron, powder, or the like is used. Further, the material and amount thereof are appropriately selected so that the temperature relationship with the cable conductor 10 is constant (for example, approximately equal) when high-frequency induction heating is performed.

Compared to when the outside is air, heat does not escape to nothing. Also, since the cable conductor 10 is in a similar situation (surrounded by plastic), the monitoring of the cable conductor 10 is facilitated.

周波誘導加熱用のコイル２８を巻く。 A non-metallic pressure cylinder 22 is placed over the metal support layer 18. A small chamber 24 is connected to the pressurizing cylinder 22, and a pressurized gas source 26 is connected thereto. A coil 28 for high frequency induction heating is wound around the pressurizing cylinder 22.

0 and the metal body 19, the temperature distribution in the radial direction is determined in advance. The temperature is adjusted while detecting the temperature of the metal body 19 with the sensor 20, and the connection part insulator 1

The metal support layer 18 also melts, and a portion of it flows out into the small chamber 24 due to expansion. A gas 27 is fed into the chamber 24 from a pressurized gas source 26 and its pressure is applied to the connection insulator 16 via the metal support layer 18 .
このようにして、接続部絶縁体１６のモールド

できるようになる。Effects of the Invention It is not possible to directly attach the temperature detection sensor 20 to the connection part 12. However, if the sensor 20 is attached to the metal body 19 that becomes an external heating element as in the present invention, the temperature relationship between the cable conductor 10 and the metal body 19 during high-frequency induction heating can be made constant in advance (for example, almost equal)
By doing so, the temperature of the cable conductor 10 can be indirectly known, and the temperature can be appropriately adjusted based on it. Therefore, there is no need to worry about overheating as in the past, and molding can be performed under the most appropriate temperature conditions.
