Abstract

The invention discloses an overhead electric power fitting. The overhead electric power fitting comprises a base body, a planar nut, two sets of press claw assemblies and a core rod, wherein the core rod is arranged in a pipe cavity of a sliding pipe of the base body, the base body is provided with the sliding pipe and radial guide limitation holes, the radial guide limitation holes are formed in the sliding pipe, the planar nut sleeves the outer peripheral wall of the sliding pipe of the base body and is arranged between the two sets of press claw assemblies, each press claw is arranged in corresponding one of the radial guide limitation holes, a planar thread part is arranged at each of two side ends of the planar nut, each planar thread part is adaptively engaged with driving thread parts of three press claws in adjacent one set of press claw assembly, the core rod is provided with three arc clamping grooves, each arc clamping groove and the inner wall of corresponding one press claw are clamped to form a wire clamping hole, and the planar nut synchronously drives the two sets of press claw assemblies to get close to or deviate from the center of the sliding pipe. The overhead electric power fitting has a relatively high loosening prevention effect.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings for overhead lines. Background technique [0002] In the construction of overhead power lines, when the cables need to be branched or spliced, it is necessary to connect two insulated wires together with piercing clamps. The puncture clamp has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. Cable branches can be made without cutting off the main cable or stripping the insulation layer of the cable. The joints are completely insulated and can be used for live work, and can be branched at any position on the cable; no terminal box or junction box is needed; and the joints are resistant to twisting, Shockproof, waterproof, anti-corrosion and aging; using insulation piercing clamps as cable branches, the comprehensive benefits are obvious, and the cost performance is better than the traditional connection methods in the past. [0003] The...
