## Abstract

A novel end aluminum part including a first cylinder (1) for accommodating a conductor (7) of an aluminum wire (5), a second cylinder (2) for abutting an insulation layer (6) of the aluminum wire (5), and a third cylinder (3) for accommodating the aluminum wire (5). The first cylinder (1) is connected to the top of the second cylinder (2), and the third cylinder (3) is connected to the bottom of the second cylinder (2). An inner diameter of the bottom of the second cylinder (2) is larger than an inner diameter of the top of the second cylinder (2), an inner diameter of the first cylinder (1) is the same as the inner diameter of the top of the second cylinder (2), and an inner diameter of the third cylinder (3) is the same as the inner diameter of the bottom of the second cylinder (2). The second cylinder (2) will not only reduce the stress between the insulation layer and the end aluminum part, so as to reduce the possibility of cracking or breakage of the end aluminum part due to excessive concentration of stress during crimping with the aluminum wire, but also prevent the insulation layer from being pressed into the conductor

## Claims

### Claim 1

A novel end aluminum part comprising a first cylinder for accommodating a conductor of an aluminum wire, a second cylinder for abutting an insulation layer of the aluminum wire, and a third cylinder for accommodating the aluminum wire, wherein the first cylinder is connected to the top of the second cylinder, and the third cylinder is connected to the bottom of the second cylinder; the first cylinder and the third cylinder are both hollow column-shaped, and the second cylinder is hollow frustum-shaped; an inner diameter of the bottom of the second cylinder is larger than an inner diameter of the top of the second cylinder, an inner diameter of the first cylinder is the same as the inner diameter of the top of the second cylinder, and an inner diameter of the third cylinder is the same as the inner diameter of the bottom of the second cylinder.

### Claim 2 (depends on 1)

The novel end aluminum part according to claim 1, wherein the top of the first cylinder is provided with a baffle.

### Claim 3 (depends on 2)

The novel end aluminum part according to claim 2, wherein a center position of the baffle is provided with a through hole.

### Claim 4 (depends on 3)

The novel end aluminum part according to claim 3, wherein an inner diameter of the through hole is smaller than the inner diameter of the first cylinder.

### Claim 5 (depends on 1)

The novel end aluminum part according to claim 1, wherein the inner diameter of the first cylinder is 1 to 3 times the diameter of the circumscribed circle of the conductor.

### Claim 6 (depends on 1)

The novel end aluminum part according to claim 1, wherein the inner diameter of the third cylinder is 1 to 3 times the diameter of the circumscribed circle of the insulation layer.

### Claim 7 (depends on 1)

The novel end aluminum part according to claim 1, wherein a projection length of the second cylinder in an axial direction thereof is 0.01 to 1.7 times the sum of lengths of the first cylinder and the third cylinder.
