Sleeve-type cable clamp device

Abstract

The invention provides a sleeve-type cable clamp device, which comprises a cable clamp body, an inner sleeve, an outer sleeve and a locking nut, wherein the inner sleeve is arranged at the inner side of a hollow cavity of the cable clamp body; the outer sleeve sleeves the outer side of the inner sleeve; the inner sleeve and the outer sleeve are matched with each other through a conical surface; the locking nut is screwed and engaged with the cable clamp body; the locking nut pushes the outer sleeve to extrude the inner sleeve inwards in the screwing process; and the inner diameter of the inner sleeve shrinks. The sleeve-type cable clamp device has the beneficial effects that the problems that a bolted cable clamp with an open structure is poor in pollutant-resistance and a hidden danger of an accident is caused by a resistance increase are solved; and the problems that a crimped cable clamp is low in clamping force, cannot be applied to a cable with a relatively large diameter and is used for one time are also solved. The cable clamp is simple and convenient to operate and applicable to cables with different sectional area and can be repeatedly used. The sleeve-type cable clamp device is simple and compact in structure, reliable in performance and very applicable to various power transmission and distribution systems at home, and is especially applied to the current domestic environment with relatively serious air pollution.

Description

technical field [0001] The invention relates to a ferrule-type cable clamp device, which can be used for reliable fastening and connection of power cables and ordinary wires with various power transmission and transformation equipment and power distribution equipment, and can also be used for power cables and various equipment connection of conductive busbars. technical background [0002] At present, in domestic power transmission and distribution systems, cable clamps are generally used to connect various power equipment and conductive cables. The cable clamps widely used in China are mainly divided into two types: bolted type and crimped type. The bolted cable clamp is an open structure with a simple structure, but more bolts are used to ensure the holding force, and the wires at the connection between the cable and the cable clamp are exposed. After use, the contact resistance between the clamp and the cable increases, resulting in serious heating, increased line loss,...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a ferrule-type cable clamp device, which is beneficial to solve the problem that the cable in the current bolt-type clamp structure is directly exposed to the atmosphere and has poor anti-pollution and anti-oxidation capabilities. The problem of narrow application range of type wire clamp

[0005] The effect of the present invention is that the wire clip device solves the problem that the bolted wire clip with an open structure has poor anti-pollution ability, and long-term use leads to an increase in the resistance of the contact surface between the wire clip and the cable, which causes the hidden danger of accidents.
