１２が変形したり破損する等の欠点があった。In recent years, the connection part (or termination part) of a rubber or plastic cable as shown in FIG.
Or on the cable core 11) is now widely used, but according to this method, the axial hole of the rubber molded insulation reinforcing tube 12 is designed to be smaller than the outer diameter of the cable core 11. Therefore, when inserting the reinforcing tube 12 onto one of the cable cores 11 to be connected, and when pulling the reinforcing tube 12 inserted over the core onto the conductor connection part 13, the frictional resistance is extremely large, and a lubricant is applied to the interface. Even if applied, a large pressing force is still required, and special tools must be used especially in the case of large connections for high voltage, resulting in disadvantages such as deformation or damage of the molded insulation reinforcing tube 12. was there.
本発明は斯る欠点を解消する目的でなされたもので、地
下図面によって本発明の一実施例を説明する。The present invention has been made to eliminate such drawbacks, and one embodiment of the present invention will be described with reference to underground drawings.

First, an insulation reinforcing tube 2 to be inserted into the cable conductor connection part (or termination part) is inserted into the circumferential groove shown in Figure 2. A plurality of rounded annular bearings 4 are provided to protrude in the longitudinal direction, and the cylinder is slid over and covered with a two-split cylinder 3 whose inner diameter is slightly larger than the outer diameter of the cable core 1, and the cylinder is covered with an insulating reinforcing cylinder 2. body 3
After inserting the cable conductor over one of the cable cores 1 to be connected as shown in the figure and connecting the cable conductor with a sleeve,
Cover the insulation reinforcing tube 2 in advance and pull the cylindrical body 3 inserted over the cape core 1 onto the cable conductor connection part 5 as shown in FIG. , connect both ends of the insulation reinforcing tube 2 to the cable core 1.
, 1 and pulled out, the cylindrical body 3 is divided into two, disassembled, and removed from above the cable core 1.

く向上する等の利点がある。According to the present invention, as described above, the insulating reinforcing tube 2 that is fitted onto the cable conductor connection portion is divided into two parts with a plurality of annular bearings 4 protruding in the longitudinal direction and the inner diameter of which is slightly larger than the outer diameter of the cable core. Slide the bearing onto the cylindrical body 3 and insert the insulation reinforcing tube 2 onto the cable core 1 through the cylindrical body 3, so when inserting it onto one cable core and onto the cable conductor connection part 5. is extremely easy to move,
Further, when the cylindrical body 3 is pulled out from the insulation reinforcing tube 2 after being moved to a predetermined position, the resistance is only the rolling friction of the bearing and does not require a large force, so the insulation reinforcing tube 2 can be inserted easily and quickly. Unlike the conventional method, there is no fear that the insulation reinforcing cylinder will be damaged or deformed during insertion, and there are advantages such as a marked improvement in work efficiency.
