The invention has better anti-loosening effect.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings for overhead lines, and in particular relates to an electric power connection fitting with better clamping fastness. Background technique [0002] In the construction of overhead power lines, when the cables need to be branched or connected, it is necessary to use power line connecting fittings to connect two insulated conductors together. Power line connection fittings have 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 insulated power line connection fittings as cable b...
