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

Abstract

The invention discloses a novel pre-twisted reinforced T-shaped wire clamp capable of preventing wire breakage. The wire clamp comprises a wire clamp main body, a drainage plate, an equipment wire clamp and a pre-twisted wire, wherein the upper end of the drainage plate is fixedly connected with the middle part of the wire clamp main body, the upper end of the equipment wire clamp is detachably fixed with the lower end of the drainage plate, the pre-twisted wire is longer than the wire clamp main body and is wound outside the wire clamp main body and the wire, and two end parts of the wire clamp main body are tightly pressed outside a lead when the wire clamp main body is fixed on the lead. A layer of preformed armor rod is wound on the outer sides of the wire clamp body and the wire, andthe length of the preformed armor rod exceeds the crimping area, so that the rigidity of the crimping outlet part is improved, the stress concentration phenomenon of the non-crimping end of the hydraulic T-shaped wire clamp is reduced, the flow guide area is increased, the flow guide characteristic of the T-shaped wire clamp is improved, and the problem of water inflow corrosion in the prior art is solved.

Description

technical field [0001] The invention relates to a T-shaped wire clip, in particular to a novel anti-broken pre-twisted reinforced T-shaped wire clip. Background technique [0002] The T-shaped clamp connects the wire and the branch line to transmit the fittings for the electrical load. At present, T-shaped wire clamps mainly include bolt-type T-shaped wire clamps and hydraulic type T-shaped wire clamps according to the installation type. Among them, the bolt-type T-shaped clamp is used to fasten the wire by the compression force of the screw, so its grip on the wire is much smaller than that of the compression type, and the performance of the bolts purchased by different manufacturers is different, and the torque required for installation At the same time, it is used in areas with strong wind and heavy ice, and is affected by the environment such as breeze and vibration, and issues such as bolt loosening need to be considered. The installation of hydraulic T-shaped clamps ...

Problems solved by technology

The open end is easy to accelerate the wear of the wire steel core and aluminum monofilament, which makes the line have hidden dangers during operation

[0004] Secondly, the existing T-shaped cable clamp structure has stress concentration at the installation point. During operation, affected by factors such as long-term breeze vibration, it is easy to accelerate the wear of the wire steel core and aluminum monofilament, making the line in the process of operation. There are hidden dangers in

The existing T-shaped clamps and equipment clamps are fixed by double bolts on a single plate. The drainage plate is easy to bend and deform during operation, and the small resistance of the contact surface is easy to generate heat.

The crimping tube of the existing T-shaped clamp adopts an up-and-down asymmetric drawer structure, and the welding drain plate cannot be crimped. After crimping, there are gaps in the crimping tube and the crimping is not solid, and the contact resistance with the wire is relatively large.
