Novel pre-twisted support type T-shaped wire clamp capable of preventing wire breakage

Abstract

The invention discloses a novel pre-twisted supporting type T-shaped wire clamp capable of preventing wire breakage. The wire clamp comprises a wire clamp main body, a drainage plate and two groups ofsupport twisted wires, wherein the wire clamp body is sleeved on the conductor, two ends of the wire clamp body are tightly pressed on the outer side of the conductor, one end of the drainage plate is fixed in the middle of the wire clamp body, one ends of the two groups of support twisted wires are respectively wound on the conductor at two ends of the wire clamp body, and the other ends of thetwo groups of support twisted wires are wound on the lower end of the drainage plate and the drainage wire. The drainage plate is welded in the middle of the wire clamp main body, and the crimping area of the wire is changed from the original one side to two-side symmetrical crimping, so that the concentrated stress of a single side to the wire is reduced; and meanwhile, the two sides are all tightly crimped, so that the problem of water accumulation in the prior art is solved, and corrosion of the wire clamp and the wire is avoided.

Description

technical field [0001] The invention relates to a T-shaped wire clamp, in particular to a novel anti-breakage pre-twisted support type T-shaped wire clamp. Background technique [0002] The T-shaped clamp connects the wire and the branch line to transmit the fittings for the electrical load. For small cross-section wires, clamp oval tubes are used for T-connection, and manual crimping pliers are used for crimping, which is rarely used; for large cross-sections, bolt-type and aluminum crimping tubes are used. Any kind of T-shaped clamp should ensure sufficient contact pressure with the wire to obtain stable contact. Bolt-type T-shaped cable clamps are more convenient to install and disassemble, and the wires are fixed by the pressing force of the bolts, but whether the electrical contact of the cable clamps is stable or not mainly depends on the installation quality of the operator, as well as the differences in the torque of the bolts of various manufacturers. The grip is ...
