Description

Technical Field

[0001] The present application relates to the technical field of wiring harness terminals, and in particular to a wiring harness terminal based on a copper-aluminum transition plate. Background Art

[0002] The copper-aluminum transition plate is a transition plate used to connect copper and aluminum. Due to the different chemical properties of copper and aluminum, directly connecting them will produce an electrochemical reaction and easily corrode in a humid environment. Therefore, it is used to connect copper wires and aluminum wires to ensure the stability and safety of current transmission.

[0003] After searching, the announcement number is CN212412220U, which discloses a copper-aluminum transition terminal for the transition connection between the copper end of the equipment and the aluminum conductor, including an aluminum terminal and a copper-aluminum composite transition piece. The aluminum terminal includes an aluminum tube and a terminal plate part connected to one end of the aluminum tube, and a copper-aluminum composite transition piece is bonded to the terminal plate part. The copper-aluminum composite transition piece has an aluminum sheet and a copper sheet connected to the aluminum sheet. The aluminum sheet is bonded and connected to the terminal plate part. The copper sheet is used to connect the copper end of the equipment. The copper-aluminum composite transition piece and the terminal plate part form a crimping end, and a mounting hole is provided on the crimping end. The copper-aluminum composite transition piece realizes a tight transition connection between the copper end of the equipment and the aluminum conductor. The copper-aluminum composite transition piece does not require friction welding and has high production efficiency. The copper and aluminum transition contact of this structure is sufficient, and its surface is completely covered with copper. During installation and use, direct contact between the conductor end and the equipment end is completely avoided, and the connection is good and the performance is stable.

[0004] However, existing wiring harness terminals are often made of die-cast copper sheets. Although this can provide good conductivity and corrosion resistance, the use of copper materials will increase the manufacturing cost of the wiring harness terminals. At the same time, due to the poor plasticity of copper wiring harness terminals in daily use compared to aluminum wiring harness terminals, it is more likely to cause wire stripping and falling off when connected to the end wires of the wires.

[0005] Therefore, it is necessary to provide a wiring harness terminal based on a copper-aluminum transition plate to solve the above problems.
