The receiving hole 201 is used to embed a cable and electrically connect to another high-voltage component through the cable. The conductive element 20 is passed through and fixed inside the insulator 30. The outer wall surface of the conductive element 20 is provided with a limiting portion (not shown), and the limiting portion is used to limit the movement of the conductive element 20 relative to the insulator 30 along the axial direction of the insulator 30.

[0111] In this embodiment, the insulator can reliably fix the conductive element inside the insulator, can effectively protect the conductive element and the cable, and improve the reliability of the electrical connection between high-voltage components.

[0112] In this embodiment, the limiting portion is a barb portion, and the inner wall surface of the insulator is provided with a recessed portion, and the recessed portion is adapted to the barb portion. The barb portion has a first inclined surface and a second inclined surface, and the first inclined surface and the second inclined surface both have a head end and a tail end, the head end of the first inclined surface is connected to the outer wall surface of the conductive element, the tail end of the first inclined surface is connected to the head end of the second inclined surface, and the tail end of the second inclined surface is connected to the outer wall surface of the conductive element, and relative to the first inclined surface, the second inclined surface is close to the tail end of the conductive element; a first angle is formed between the tail end of the first inclined surface and the head end of the second inclined surface, and the first angle is greater than 0° and less than 90°; a second angle is formed between the head end of the first inclined surface and the outer wall surface of the conductive element, and the second angle is greater than 90° and less than 180°; a third angle is formed between the tail end of the second inclined surface and the outer wall surface of the conductive element, and the third angle is greater than 0° and less than 90°. The barb portion has a simple structure and can relatively reliably fix the conductive element inside the insulator, which is beneficial to improving the reliability of the electrical connection between high-voltage components.

[0113] like Figure 1-3 As shown, the outer wall surface of the conductive element 20 is provided with a first positioning portion 202 that protrudes radially outward, the inner wall surface of the insulator 30 is in contact with the outer wall surface of the first positioning portion 202, and the barb portion is provided on the outer wall surface of the first positioning portion 202. In addition, the outer wall surface of the first positioning portion 202 is provided with a groove, and the inner wall surface of the insulator 30 is provided with a first abutting portion 301 that matches the groove, and the first abutting portion 301 is used to limit the movement of the conductive element 20 relative to the insulator 30 along the axial direction of the insulator 30.

[0114] In this embodiment, the groove in the first positioning portion cooperates with the first abutting portion, so that the conductive element can be more reliably fixed inside the insulator, which is more conducive to improving the reliability of the electrical connection between high-voltage components.

[0115] like Figure 1-3 As shown, the high-voltage plug 10 further includes a centering block 40, which is a cylindrical structure, and is connected to the accommodating hole 201. The centering block 40 is sleeved on the outer wall surface of the tail end of the conductive element 20, and is fixed against the conductive element 20. In addition, one end of the centering block 40 abuts against the first positioning portion 202 of the conductive element 20, and a protrusion 401 extends toward the central axis on the inner wall surface of the centering block 40, and the tail end of the conductive element 20 abuts against the protrusion 401.

These centering units may be completely identical, partially identical or completely identical. In addition, these centering units may be separated in a direction parallel to the axis of the centering block, or in a direction inclined to the axis of the centering block.

[0119] like Figure 1 and Figure 2 As shown, the high-voltage plug 10 further includes a shell 50, the insulator 30 and the shell 50 both have a head end and a tail end, the insulator 30 is passed through and fixed inside the shell 50, the head end of the insulator 30 is close to the head end of the shell 50, and the tail end of the shell 50 has an opening, which is connected to the accommodating hole 201. The shell can protect the insulator, conductive elements and cables, which is more conducive to improving the reliability of electrical connection between high-voltage components.
