Embodiment

[0011] An insulating cap for wires, which includes a trumpet-shaped insulating cap 2 made of rubber and a nut 1 installed outside the insulating cap 2. Threads matching the nut 1 are processed on the outer surface of the insulating cap. Nut 1 is made of metal, hard plastic or hard rubber, and it is non-deformable. The left side of the insulating cap 2 is conical, and the right side is cylindrical. A blind hole 2.3 is provided in the frustum-shaped insulating cap 2 at the bell mouth end. Around the blind hole, that is, the frustum-shaped insulation cap, cut out some longitudinal gaps 2.1, so that this part forms several claws 2.2 whose cross-section is fan-shaped, and the fan-shaped central angle of the claw 2.2 is 26 degrees. During use, the cable ends are inserted in the blind hole 2.3 of the insulating cap 2, and when the nut 1 is rotated forward, several claws 2.2 at the front end of the insulating cap 2 are tightened and closed, and the cable ends are wrapped therein.

Abstract

The invention provides a wire insulation cap, comprising a trumpet-shaped insulation cap made of rubbers and a nut arranged outside the insulation cap, wherein an outer surface of the insulation cap is provided with a thread matched with the nut; the insulation cap is internally provided with a blind hole; and the insulation cap around the blind hole is cut to form a plurality of longitudinal notches so as to form a plurality of claws. The wire insulation cap can be substituted for a PVC (polyvinyl chloride) insulating tape to carry out insulation protection on cable thread ends, thus preventing short circuit or injuries caused by overlapping multiple test thread ends, improving the field operation safety and the working efficiency and being convenient to use.

Description

technical field [0001] The invention belongs to the technical field of electric power transmission, and in particular relates to a safety protection device for electric power system relay protection and other professionals working on a secondary circuit. Background technique [0002] In the process of testing the relay protection of power systems, it is often necessary to disconnect the cable ends of some devices, and many of these ends are live. It is very cumbersome to wrap them with tape, etc., and they are easy to fall off, with high potential risks. Contents of the invention [0003] In order to solve the problem of inconvenient binding of cable ends when the relay protection of power system and other professionals work on the secondary circuit, the following technical scheme is proposed. [0004] A wire insulating cap, which is special in that it includes a trumpet-shaped insulating cap made of rubber material and a nut installed outside the insulating cap. The oute...
