Embodiment Construction

[0029] Such as Figure 1 to Figure 5 As shown, a wire quick connection device is composed of the following parts.

[0030] The static pressure plate 1 of the aluminum alloy casting has a T-shaped profile as a whole. On the front top of the static pressure plate, there are jaw protrusions 11 on the same straight line and circular holes arranged on both sides, wherein the jaw protrusions and the movable The pressing plate cooperates to form a jaw, and when the movable pressing plate moves closer to the protrusion of the jaw, a clamping action is formed, which can clamp the wire. Two arc-shaped guide grooves 12 arranged in a figure-eight shape are arranged symmetrically on the face plate of the static pressure plate.

[0031] The two vertical tie rods 2 are also aluminum alloy castings, and the top of each vertical tie rod is slip-knotted on the round holes on both sides of the static pressure plate through round pins 6 to form a hinged connection. Round pin holes are respectiv...

Abstract

The invention relates to a quick wire connecting device and a live wire connecting structure. The live wire connecting structure comprises a first wire, a second wire and two quick wire connecting devices, wherein the first wire and the second wire are to be connected. Shunt line pressing nuts of the two quick wire connecting devices are linked respectively through one copper wire. Jaws formed by jaw protrusions in dynamic press plates and static press plates in the two quick wire connecting devices are clamped on the first wire and the second wire respectively. The problem that in transmission and distribution line equipotential operation, due to usage of a parallel groove clamp, drainage wires are difficult to connect and install is solved. Accordingly, the live wire connecting structure is a replacement tool of the parallel groove clamp.

Description

technical field [0001] The invention relates to a tool used in the maintenance and repair process of electric facilities, in particular to a device for quick connection of wires used in the live work maintenance process. Background technique [0002] In the operation and maintenance of power transmission and distribution lines, live treatment of overheated connection equipment, replacement of switches, knife switches, poor connection of connectors, opening and re-connection, etc., all need to set up temporary drainage lines. The method currently adopted is to use wires to connect with parallel trench clamps. [0003] The parallel groove clamp is used for the connection of small and medium-sized aluminum stranded wires or steel-cored aluminum stranded wires and the steel stranded wires of overhead lightning conductors at positions that do not bear tension. It is also used for jumper connections of non-linear poles and towers. At present, the use of wires to connect with para...
