## Abstract

According to an embodiment, a method for manufacturing a safety busbar comprises placing a second conductor on each of two opposite ends of a first conductor, performing linear friction welding between the first conductor and the second conductor, and cutting the first conductor to a predetermined depth.

## Claims

### Claim 1

A method for manufacturing a safety busbar, the method comprising:
placing a second conductor on each of two opposite ends of a first conductor;
performing linear friction welding between the first conductor and the second conductor; and
cutting the first conductor to a predetermined depth.

### Claim 2 (depends on 1)

The method of claim 1, wherein the first conductor is formed of aluminum.

### Claim 3 (depends on 1)

The method of claim 1, wherein the second conductor is formed of copper.

### Claim 4 (depends on 1)

The method of claim 1, further comprising forming a notch in a middle of the first conductor.

### Claim 5 (depends on 1)

The method of claim 1, further comprising etching the first conductor.

### Claim 6 (depends on 1)

The method of claim 1, further comprising performing first surface treatment on two opposite side surfaces of the first conductor and performing second surface treatment on a side surface of the second conductor.

### Claim 7 (depends on 1)

The method of claim 1, further comprising coating the first surface with a coating material, wherein the coating material includes a resin.

### Claim 8 (depends on 1)

The method of claim 1, further comprising:
installing a spacer on the first conductor; and
installing a tube on the first conductor, with the spacer interposed between the first conductor and the tube, wherein a space is formed between the tube and the first conductor.

### Claim 9 (depends on 1)

A safety busbar manufactured by the method of claim 1.

### Claim 10

A safety busbar, comprising:
a first conductor formed of aluminum; and
a second conductor formed of copper, the second conductor formed on each of two opposite sides of the first conductor, wherein the first conductor is formed to have a smaller thickness than the second conductor.

### Claim 11 (depends on 10)

The safety busbar of claim 10, wherein a notch is formed in a middle of the first conductor.

### Claim 12 (depends on 10)

The safety busbar of claim 10, wherein a terminal hole are formed in an end of the second conductor.

### Claim 13 (depends on 10)

The safety busbar of claim 10, wherein the first conductor is coated with a resin.

### Claim 14 (depends on 10)

The safety busbar of claim 10, further comprising:
a spacer formed on the first conductor; and
a tube formed on the first conductor, with the spacer interposed between the first conductor and the tube, wherein a space is formed between the tube and the first conductor.
