Machined terminal structure capable of preventing explosion of copper wire

Abstract

The invention relates to a machined terminal structure capable of preventing explosion of a copper wire. The machined terminal structure comprises a cable plug; the right side of the cable plug is provided with a connection part and a wrapping part which are integrally formed through mechanical stamping; an aluminum foil layer is arranged inside the sidewalls of the connection part and the wrapping part; and the outer side of the aluminum foil layer is provided with a steel wire layer. When the machined terminal structure is used, the connection part and the wrapping part which are integrallyformed through mechanical stamping have the advantages of high overall strength and low possibility of being bent and damaged; the aluminum foil layer can increase the axial tensile strength of the connection part and the wrapping part, the steel wire layer can increase the toughness of the connecting part and the wrapping part, and therefore, the problem of the fracture of a wire core caused by an excessively large bending angle can be effectively prevented; first bosses and second bosses can cooperate with each other so as to effectively fix and limit the position of the wire core, so that the fracture of the internal wire core caused by the pulling of a cable can be prevented; and third bosses and fourth bosses can effectively cooperate with each other, so that the problem of the exposure of the wire core (copper wire) caused by rubber sheath shrinkage can be prevented.

Description

technical field [0001] The invention relates to the field of machining, in particular to a machined terminal structure capable of preventing exposed copper wires. Background technique [0002] With the advancement of science and technology and the development of society, my country's machining industry has developed rapidly, followed by the rapid development of machining parts. [0003] At present, electric vehicles are the future development trend, and in the connection of electric vehicle lines, strong current lines are particularly critical. Usually, the strong electric circuit is connected through the cable plug and the socket connected to the battery, and the cable core (copper wire) and the plug are usually connected together by mechanical stamping, and during use, due to bending If the angle is too large, the wire core will be broken, which will lead to the disconnection of the strong current line; or the rubber will shrink due to pulling, which will lead to the expo...
