A piercing electric fitting

Abstract

The invention discloses a puncture-type electric power fitting, and the electric power fitting comprises puncture systems which are adjacent in a lateral direction. Each puncture system comprises a housing, and the central part of the upper side wall of each housing is provided with an adjustment head, wherein the adjustment head vertically passes through the central part of the upper side wall ofthe housing. The interior of each adjustment head is provided with an adjustment rod, and the lower end of each adjustment rod is provided with a puncture needle. The upper and lower sides of the outer side wall of each adjustment rod are provided with limiting rings. The interior of each housing is provided with a fixed seat between the upper and lower limiting rings. The interior of each fixedseat is provided with an adjustment nut, and each adjustment nut is in threaded connection with the corresponding adjustment rod. The central part of the lower side wall of the hosing is provided witha first clamping groove, and the lower side wall of the housing and the upper side of the first clamping groove are provided with puncture holes in a passing-through manner. The upper surface of an inner cavity of each housing is provided with resetting seats in a manner of lateral symmetry. The left and right ends of the upper side wall of each housing are provided with resetting through holes in a passing-through manner. The electric power fitting can clamp wires with different diameters, can firmly clamp the wires, and facilitates the removing of the wires.

Description

technical field [0001] The invention relates to the technical field of electric power fittings, and specifically relates to a puncture-type electric fitting. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. Piercing type power fittings can take electricity from the wires and pierce the insulator protective layer of the wires , have good contact with the conductor, so as to lead out the electric energy and introduce part of the current in the main line into the branch line. The existing puncture-type power fittings may loosen when fixing the wires due to the different thickness of the wires. It is inconvenient to need tools to operate, and it is difficult to remove after fixing, which is not conducive to subsequent maintenance operations. Contents of the invention [0003] The purpose of the present invention is to provi...
