Abstract

The utility model relates to the technical field of electric power fittings, and especially relates to a novel wedge-shaped strain clamp. The novel wedge-shaped strain clamp comprises a housing, a pull ring, and a left wedge block and a right wedge block which are in pairs, wherein the housing is internally provided with a wedge-shaped hole, the left wedge block and the right wedge block are inserted into the wedge-shaped hole in an opposed manner, a wire hole for clamping a wire is disposed inside both the left wedge block and right wedge block, the outer faces of the left wedge block and the right wedge block are inclined faces matched with the wedge-shaped hole, suspension loops are disposed on the two sides of the rear end of the housing, the two front ends of a U-shaped pull ring penetrate through the suspension loops, and the front ends of the pull ring are provided with torsion nuts. The novel wedge-shaped strain clamp is simple and reasonable in structure, the wedge-shaped housing and the wedge blocks coordinate with each other and are driven and clamped by the self weight of cables, and the pull ring is fixed on a cable pole and fastened through the torsion nuts, so the standard grip among the housing, the wedge blocks and the cables is achieved, and the novel wedge-shaped strain clamp is stable in connection and convenient to mount.

Description

Novel wedge-shaped strain clamp
Technical field
The utility model relates to electric armour clamp technical field, particularly Novel wedge-shaped strain clamp.
Background technology
Along with the progress in epoch and scientific and technological development, the also vigorous growth of China's power industry technologies, the construction of various power infrastructures has also entered brand-new developing period.And the problem existing in disconnected etc. use is resisted in circuit installation, line security, lightning protection, existing various electric armour clamps are proposed to higher requirement.Strain clamp is wherein for fixed cable, to bear the tension force between cable circuit, and by cable hang with string group or shaft tower on gold utensil.
Existing strain clamp generally adopts screw bolt-type and wedge strain resistance cable clamp, the wire clamp of the type can repeated removal use after installing on wire, wedge strain resistance cable clamp is wherein the contraction of sliding in adaptive cavity according to the slide block of wedge shape, and then drive and clamping wire design principle that it is locked.Existing strain clamp processing and installation more complicated, need to be fixed wire by many groups U-bolt, and every group of bolt is wayward by manual operation to the tautness of wire clamp, and wire clamp is unequal to the pressure of wire, makes grip not reach the requirement of national standard.Therefore, be necessary current technology to improve.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of compact conformation, easy to use.
For achieving the above object, the utility model is by the following technical solutions:
Novel wedge-shaped strain clamp described in the utility model, the left and right voussoir that comprises housing, draw ring and two pairings, in described housing, be provided with wedged hole, two left and right voussoirs are relatively inserted in wedged hole, the wire guide of clamping wires is all established in voussoir inner side, left and right, and the lateral surface of left and right voussoir is the inclined-plane coordinating with wedged hole; Both sides, described housing rear end are provided with hangers, and two front ends of U-shaped draw ring are arranged on hangers, and the front end of draw ring is provided with torque nut.
Further, described hull outside is interval with some reinforcements, and some reinforcements are uniformly distributed along housing rear and front end.
Further, voussoir rear end, described left and right is equipped with lead-in wire handle, and lead-in wire handle inboard has wire lead slot, and lead-in wire handle end is provided with bolt clip plate.
Further, described in, be located at the teeth groove that on the voussoir of left and right two lead-in wire handle front ends are provided with pairing.
The utility model beneficial effect is: the utility model is simple and reasonable, by wedge shape housing, coordinate with voussoir, by cable deadweight, driven and clamped, draw ring is fixed on online bar and is screwed by torque nut, guarantee to reach standard grip between housing, voussoir and cable, stable connection is easy for installation.
