End plate wire fixer

Abstract

The invention relates to the field of power wire connection equipment, in particular to an end plate wire fixer; it comprises an upper clamp plate, a lower clamp plate, an arc-shaped washer, a torque nut, a disc spring washer and a screw rod; the arc-shaped washers are buckled with each other There are toothed arc grooves on the clamping wire, the upper splint and the lower splint respectively, the bottom of the lower splint is provided with a threaded hole, the threaded hole cooperates with the screw to lock the fixed screw, and the upper surface of the upper splint is arc-shaped , which is provided with a hole for the screw to pass through, the lower surface of the arc-shaped gasket is designed with an arc that matches the upper surface of the upper splint, and the arc-shaped gasket is provided with a hole for the screw to pass through. The moment nut is located above the arc-shaped washer and connected with the screw rod; the end plate wire fixing device of this technical solution has a large holding area when the wire is clamped, and is reliable and versatile.

Description

technical field [0001] The invention relates to the field of electric wire connection equipment, in particular to an end plate wire fixer. Background technique [0002] Power connection fittings are commonly used devices when circuit breakers, isolating switches, fuses, transformers and other electrical equipment are connected to wires, and play a very important role. [0003] At present, the most common power connection fittings are flat bolt-fastened equipment connection clamps, such as the clamps announced in the comparative document CN202259748U, which include upper and lower splints that are interlocked to realize wire clamping. The clamp body is Made of non-magnetic aluminum alloy, one side of the upper splint is provided with two downward-curved claw-shaped structures along the clamping direction, and one side of the corresponding lower splint is provided with three upward-curved claw-shaped structures, the same The distance between the adjacent claw-shaped structure...

AI Technical Summary

Problems solved by technology

[0005] 1. Although a certain tightening torque is maintained when the nut is used for locking installation, the tightening torque is often not constant. Even if the torque nut has been used, there is still a situation where the wire cannot be effectively compressed, resulting in the contact between the wire and the clamp Defective and affect the safe operation of the power grid

[0006] 2. The end plate head protruding from one or both ends of the lower splint occupies a large volume, which not only makes the end plate wire fixer much heavier as a whole, but also requires a lot of cutting on the basis of the original lower end plate blank , grinding and other processes, the processing cost is relatively high
