Anti-breaking anti-loosing copper and aluminum adapter clamp

Abstract

The invention relates to the technical field of copper and aluminum adapter clamps, and provides an anti-breaking anti-loosing copper and aluminum adapter clamp, which comprises a copper body, an aluminum body and a set screw, wherein the left end of the copper body is provided with a copper sheet with a wiring hole; the right end of the copper body and the left end of the aluminum body are fixedly connected together through welding to form a welding joint surface, and the welding joint surface is an inclined plane; the right part of the aluminum body is internally provided with a cable slot with an opening facing the right; and at least two thread screw holes are distributed at left-right intervals on the aluminum body at the upper end of the cable slot. The welding joint surface is the copper body and the aluminum body with the inclined plane, the joint area is large, the strength is high, and breaking by an external force does not happen easily; the joint surface is connected more firmly, the breaking condition generated by heating oxidization is improved, and the service life is long; the end part of the cable is pressed and fixed in the cable slot of the aluminum body through the set screw and a damping pressure plate, assembly and disassembly are convenient, regular screwing and tightening can be carried out by using repair time, firm connection is kept constantly, a wiring loosing condition is improved, line interruption is avoided, and normal operation of the power grid is ensured.

Description

technical field [0001] The invention relates to the technical field of copper-aluminum transition clamps, and relates to a break-proof and loose-proof copper-aluminum transition clamp. Background technique [0002] In the power system, a large amount of conductive materials need to be consumed. The terminals of many devices are made of copper, and the overhead wires are mostly made of aluminum. Therefore, it is necessary to use copper-aluminum transition clamps to connect copper wires and aluminum wires; Including the copper body and the aluminum body; the copper body and the aluminum body are fixed by welding; when wiring is used, the copper-aluminum connection of the copper-aluminum transition clamp will produce contact resistance, resulting in heating and oxidation; and the copper-aluminum transition clamp currently used The welding joint surface of copper and aluminum is a vertical surface with small area and poor strength. When the heat is oxidized to a certain extent, ...
