Problems solved by technology

[0003] At present, the conventional method of domestic production of copper-aluminum composite materials is welding, that is, copper and aluminum parts are welded one by one into copper-aluminum electrical connection parts. This production method requires a large number of personnel and equipment, and has low efficiency and high cost. A certain welding failure rate, limited welding joint area, difficult to fully guarantee product quality consistency, stability, and reliability, and unnecessary weight
[0004] Foreign countries use copper-aluminum continuous side composite coil stamping to manufacture electrical connection parts, but the bonding area of ​​the copper-aluminum interface is too small, the ability to prevent crack expansion is insufficient, and there is a possibility of falling off, which affects reliability; moreover, the bonding area has poor flexibility and shock resistance. Mobility weak

Embodiment 1

[0039] Such as Figure 1-5 As shown, the lateral composite copper-aluminum composite material disclosed in this embodiment includes a copper strip 1 and an aluminum strip 2, and one side of the copper strip 1 and one side of the aluminum strip 2 are made into a strip by three mortises. . In this embodiment, there are three mortises, which can double the area of ​​the copper-aluminum interface bonding area, improve the bonding strength, and improve the stability.

[0040] In this embodiment, one side of the aluminum strip 2 is provided with an aluminum tenon groove 22 along its length direction, and the aluminum tenon groove 22 runs through the two ends of the aluminum strip 2. There are three copper tenons 11 adapted to the aluminum tenons 22 , and the three copper tenons 11 are installed in one of the aluminum tenons 21 respectively. Of course, the length of the copper tenon 11 is equal to the length of the copper strip 1 . Two aluminum tenons 21 are formed between the thr...

Embodiment 2

[0056] The difference between this embodiment and Embodiment 1 is that: Figure 8 , 9 As shown, in this embodiment, the aluminum tenon 21 is thickened at the head end, and the copper tenon 12 is narrowed at the notch. Preferably, the aluminum tenon 21 is gradually thickened from the root to the head, and the copper tenon 12 is gradually narrowed from the bottom to the notch. This structure can effectively prevent copper and aluminum tenons from loosening, suppress possible crack propagation, and improve reliability.

Abstract

The invention relates to a continuous side composite copper-aluminum composite material and a manufacturing method thereof, which belong to the technical field of power transmission. The continuous side composite copper-aluminum composite material comprises a copper strip and an aluminum strip; one side of the copper strip is in mortise joint with one side of the aluminum strip to form a strip; one side surface of the aluminum strip is provided with aluminum tenon grooves, the aluminum tenon grooves pass through two end surfaces of the aluminum strip, and three aluminum tenon grooves are arranged vertically at intervals; and one side of the copper strip is provided with three copper tenons matched with the aluminum tenon grooves, and the three copper tenons are loaded in the aluminum tenongrooves respectively. The embedding depth has a large controllable interval, and due to the three tenons, the bonding zone has better flexibility and excellent anti-vibration performance, the area ofa copper-aluminum interface bonding zone can also be increased, and the bonding strength is improved. The continuous side composite copper-aluminum composite material can be efficiently punched toa large number of copper-aluminum conductive rows, the quality is reliable, non-destructive detection is easy, consistency, stability and reliability are good, and a part processing enterprise can save a lot of equipment investment and redundant personnel.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular to a continuous side composite copper-aluminum composite material and a manufacturing method thereof. Background technique [0002] In the power and battery pack industry there is a need for a large number of connections between copper and aluminum conductive bars. Copper-aluminum composite materials have been extensively researched and developed for their excellent properties. [0003] At present, the conventional method of domestic production of copper-aluminum composite materials is welding, that is, welding copper and aluminum parts one by one into copper-aluminum electrical connection parts. This production method requires a large number of personnel and equipment, and is low in efficiency and high in cost. A certain welding failure rate, limited welding joint area, it is difficult to fully guarantee the consistency, stability and reliability of product qua...
