Copper aluminum conducting wire connection structure of high safety

Abstract

The present invention provides a copper aluminum conducting wire connection structure of high safety. The copper aluminum conducting wire connection structure comprises a sleeve, a copper conducting wire, an aluminum conducting wire and a plurality of screws, the sleeve comprises a plastic inner layer and a metal outer layer, and a plurality of threaded holes are arranged at intervals on the metal outer layer and along the axial direction of the sleeve. The bare conductive core wires of the copper conducting wire and the aluminum conducting wire are placed in a fixed inner cavity of the sleeve from the two ends respectively, are interlaced parallelly and are inserted mutually, so that the circumferential surfaces of the bare conductive core wires of the copper conducting wire and the aluminum conducting wire are contacted and connected mutually and electrically. The plurality of screws penetrate the plurality of threaded holes respectively to press against the plastic inner layer to thereby lock and fix the bare conductive core wires of the copper conducting wire and the aluminum conducting wire in the fixed inner cavity. According to the present invention, the bare conductive core wires of the copper conducting wire and the aluminum conducting wire adopt an interlaced connection mode, so that the connection resistance is not generated, and the electric energy can be saved. The sleeve of the present invention is composed of the plastic inner layer and the metal outer layer, and the plastic inner layer can play an insulation part, protects the oxidation of a copper aluminum core wire, at the same time, also can realize a waterproof effect.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a copper-aluminum wire connection structure with high safety performance. Background technique [0002] At present, the connection of copper and aluminum wires is to weld the copper and aluminum together and put a sleeve on the copper-aluminum connection. Using this connection structure not only produces resistance at the copper-aluminum connection, but also the exposed conductive core wire at the electrical connection end of the copper wire and aluminum wire is easily damaged. Oxidation, short service life, and poor waterproof performance. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a copper-aluminum wire connection structure with high safety performance. [0004] A copper-aluminum wire connection structure with high safety performance proposed by the present invention includes a sleeve, a...
