Description

  The present invention relates to an electric wire support for supporting an electric wire on an insulator, and more particularly, to an electric wire support that can facilitate an operation of attaching an electric wire to an insulator or removing an electric wire from the insulator using an indirect live tool.

  Conventionally, in the distribution line work by the indirect hot-line method, the electric wire is put along the groove of the insulator, and the insulator and the electric wire are used by using an indirect hot-line tool (a hot stick with a wrapping grip tongue as a tip tool). An operation of attaching the electric wire to the insulator by winding a bind between the insulator and the insulator or removing the electric wire from the insulator by removing the bind wound between the insulator and the electric wire is performed.

  In such a work, the tip of the hot stick is operated near the arm of the electric pole, and the binding is wound between the insulator and the wire, or the binding wound between the insulator and the wire is removed. Therefore, skilled workers and inexperienced workers may damage the binding coating and reduce the quality of the binding, or remove the metal parts of the tool bit from the arm metal or the wire. May cause ground-fault accidents by contacting with the Further, since it is necessary to pay close attention to the work, the work requires time and labor, and the work efficiency is deteriorated.

  To cope with the above-described problem, for example, it is conceivable to use the technology described in Patent Document 1. The technology (bindless cap) described in Patent Literature 1 is such that a pair of half-cut clamps are pivotally supported at the upper end thereof, and when the two half-cut clamps are closed on a projecting portion provided on the lower outer surface of the lower half of the clamp. The engaging projection and the engaging hole are formed so as to match each other, and by closing both half clamps, the distribution line is clamped and the insulator is clamped at the same time.

  By using a bindless cap having such a configuration, it is not necessary to wind a bind between the insulator and the electric wire, so that the quality of the bindless cap does not deteriorate. In addition, since the bindless cap is made of synthetic resin, even if the bindless cap comes in contact with the arm or the part where the coating of the electric wire is peeled, it does not lead to a ground fault accident, and it is an inexperienced worker. Can work safely. Furthermore, by closing both half clamps, the distribution line can be clamped and the insulator can be clamped at the same time, so that the work can be performed easily and in a short time, and the working efficiency can be improved.

  However, the bindless cap described in Patent Literature 1 has a complicated structure, so that it takes time and effort to manufacture, and the manufacturing cost is high.
