ては停電時間を短縮し得ない難点があった。[Problems to be Solved by the Invention] However, in such a conventional method for forming a branch connection, since the conductor connector 2 and the conductor of each cable 3, 4 are connected by compression, if an accident occurs, The problem was that it was difficult to disconnect the accident cable, which made it impossible to shorten the power outage time.

いる（実公昭５３−３３１７９号公報参照）。On the other hand, in order to unitize the branch connection and reduce the number of on-site work, the main cable conductor is compressed and connected to both ends of a T-shaped connecting metal rod, and the main cable conductor is connected approximately at the center of the connecting metal rod. A method is known in which a branch cable is detachably connected perpendicularly to the connecting metal rod (see Japanese Utility Model Publication No. 33179/1983).

特性が劣るという難点もあった。However, in this method of forming a branch connection, the conductors of the pair of main cables to be connected are connected to both ends of the connection metal rods exposed from both sides of the unitized insulator. Therefore, there was a problem in that the axial dimension of the branch connection part became large due to the presence of a certain length of connection metal rod. In addition, an insulating protective layer is usually formed by winding an insulating tape over the joint between the connecting metal rod and the main cable conductor, but there is a drawback that it takes a long time to form this insulating protective layer.
The insulating protective layer formed by winding insulating tape has a disadvantage in that its insulating properties are inferior to molded insulators manufactured in a factory that undergoes quality control in advance.

It is an object of the present invention to provide a method for forming a branch connection part, which allows current to flow through the branch connection part and reduces the axial dimension of the branch connection part.

特徴としている。[Means for Solving the Problems] That is, the method for forming a branch connection part of the present invention has a screw hole orthogonal to the axis at approximately the center, and conductors of a pair of main cables to be connected to both ends are respectively connected. An insulating tube having a branch port approximately in the center and previously fitted into one of the main cables is placed on the straight conductor connector, which is connected to the insulating tube, so as to straddle the insulating layers of the pair of main cables, and While pulling back so that the axes of the screw hole and the branch port are aligned, the tip of the socket inserted from the branch port is screwed into the screw hole, and the conductor tip of the branch cable is attached to the rear end of the socket. It is characterized by being able to be connected detachably.

The vicinity of the ends of the connector and the insulating layer of the trunk cable are covered. Therefore, compared to a conventional branch connection, the axial dimension of the branch connection can be shortened by the amount that the tip of the trunk cable enters the insulating cylinder.
