Electric energy transmission connector and preparation method thereof

Abstract

The invention discloses an electric energy transmission connector and a preparation method thereof. The electric energy transmission connector comprises an electric energy transmission copper piece, an electric energy transmission aluminum piece and an aluminum wire. The electric energy transmission copper piece comprises a fixing piece used for being connected with an electric device and a connecting piece used for being connected with the electric energy transmission aluminum piece, a first through hole is formed in the electric energy transmission aluminum piece, a second through hole is formed in the connecting piece, an aluminum conducting core exposed after an insulating layer is stripped from the front end of the aluminum conducting wire extends into a cavity formed by connecting the first through hole and the second through hole, and the electric energy transmission aluminum piece is connected with the aluminum conducting wire in a crimping mode. The electric energy transmission copper piece is light in weight and rapid in production, and the production cost is saved. And moreover, the feeding and discharging automation of the electric energy transmission copper part and the electric energy transmission aluminum part can be realized, and the flash generated during welding is directly cut off after welding, so that the processing time is saved, and the assembly efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to an electric energy transmission joint and a preparation method thereof. Background technique [0002] At present, under the premise of reducing the weight of the wiring harness, aluminum wires will be used in large quantities. However, since most of the terminals of electrical devices are still made of copper, aluminum wires must be connected to copper parts for power transmission. Power transmission copper parts are generally solid, which is a waste of material, and solid power transmission copper parts are generally processed by hot forging, which consumes high energy, has large processing errors, and the production cost of power transmission copper parts is high. . Moreover, when the copper parts for power transmission of different shapes are connected to the aluminum wires by welding, different fixtures need to be used, which increases the cost and complicates ...

AI Technical Summary

Problems solved by technology

Power transmission copper parts are generally solid, which is a waste of material, and solid power transmission copper parts are generally processed by hot forging, which consumes high energy, has large processing errors, and the production cost of power transmission copper parts is high.

Moreover, when copper parts of different shapes for power transmission are connected to aluminum wires by welding, different fixtures need to be used, which increases costs and complicates the management of fixtures.

In addition, when welding, the aluminum wire is also welded in the welding equipment. Because the aluminum wire is relatively long and soft, it not only increases the cost of equipment tooling, but also is not easy to realize automatic production and loading and unloading. After welding, due to the aluminum Wire cannot be rotated to remove welding flash
