Abstract

The utility model relates to a lightweight wire clip. An upper and a lower clipping plates are buckled together, and the buckling surfaces of the two clipping plates is provided with two parallelly opposite concave wiring troughs which are tightly fixed by the penetration of screw bolts, screw nuts and washers from the middle. The cross sections of the plate bodies of the upper and the lower clipping plates are provided with through holes which are circular, elliptical, rectangular or polygonal in shape, wherein, the upper and the lower edges of the rectangular or the polygonal polygon holes have radian. On the basis of conforming to national standards, the utility model is made of aluminium alloy with high strength and good quality, and the shapes of the upper and the lower clipping plates of the wire clip are improved. The lightweight wire clip has the advantages of simple manufacture, material saving, light weight and low manufacturing cost, and simultaneously can ensure power transmission performance and safety performance of the wire clip to reach or exceed standard technical index. The lightweight wire clip can be used for the connection engineering of steel strands, aluminum strands or steel-cored aluminum strands of overhead power lines.

Description

Light-duty wire clamp

Technical field

The utility model relates to a kind of electric armour clamp, particularly a kind of parallel groove clamp.

Technical background

Traditional parallel groove clamp is usually cast with cast alumin(i)um, owing to consider requirement of strength, its shape must be solid design.It is snapped together by solid train wheel bridge and lower plate, and its buckling surface has parallel relative twice spill wire casing, penetrates fastening from the middle part by bolt, nut, packing ring.This parallel groove clamp just is necessary to improve its shape after adopting the fine aluminum alloy casting, under the condition that is implemented in influence technique performance not, save material, reduces cost, and alleviates the weight of wire clamp.

Technology contents

The utility model solves light-duty wire clamp under the condition that does not influence every technical performance, saves material, reduces cost, and alleviates the problem of the weight of wire clamp.

The technical scheme of light-duty wire clamp: train wheel bridge, lower plate snap together, its buckling surface has parallel relative twice spill wire casing, penetrate fasteningly by bolt, nut, packing ring from the middle part, it is characterized in that: on the plate body cross section of train wheel bridge, lower plate, penetrating hole is arranged.

The shape of above-mentioned hole is circle, ellipse, rectangle or polygon.

Wall thickness is 0.8-3.0mm between above-mentioned hole, and wall thickness is 0.8-3.0mm up and down.

There is radian on the upper and lower limit of above-mentioned rectangle or polygon hole.

On the above-mentioned spill wire casing inner face vertical or horizontal anti-skidding burr is arranged.

Beneficial effect: the utility model is meeting on the basis of national standard, adopts the manufacturing of high-quality high-strength aluminum alloy, has improved the shape of lower plate on the wire clamp, and its processing technology is simple, saves material, weight reduction, the manufacturing cost of reduction wire clamp; Guarantee that simultaneously wire clamp power delivery performance and safety and reliability meet or exceed the standard technique index, this light-duty wire clamp is applicable to steel strand wire, aluminium stranded conductor or the steel reinforced aluminium conductor of the overhead power line engineering that continues.
