Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature.

[0031] Example:
[0032] refer to Figure 1-Figure 3 A data connector for a car includes: a housing 1, an outer conductor 2, an insulator 3 and a center pin 4. A coaxial groove 11 is provided in the housing 1, and a coaxial flange 21 extends from the outer conductor 2. When the outer conductor 2 is assembled with the housing 1, the coaxial flange 21 and the coaxial groove 11 are interference-fitted. The length of the coaxial groove 11 is greater than the length of the coaxial flange 21. Therefore, when the coaxial flange 21 and the coaxial groove 11 are assembled, a receiving groove 111 is formed between one side of the coaxial groove 11 and one end of the coaxial flange 21. The receiving groove 111 is used to receive the outer conductor 2. The metal scraps generated during the assembly of the conductor 2 and the shell 1, and the metal scraps generated by the interference fit between the coaxial flange 21 and the coaxial groove 11 when the outer conductor 2 and the shell 1 are assembled, directly fall into or are pushed into the accommodating cavity, thereby avoiding the falling of metal scraps generated during assembly. The annular surface of the coaxial groove 11 is coaxial with the annular surface of the coaxial flange 21, thereby ensuring the coaxiality between the shell 1 and the outer conductor 2, and further ensuring the stability of the connection between the connector and other connectors. The insulator 3 is installed in the outer conductor 2, and the center pin 4 is installed in the insulator 3.
[0033] refer to Figure 1-Figure 3A limiting flange 22 extends outward from the outer conductor 2, and a limiting groove 12 is provided in the outer shell 1. The limiting flange 22 cooperates with the limiting groove 12 to limit the relative position between the outer conductor 2 and the outer shell 1, thereby limiting the maximum depth of the outer conductor 2 inserted into the outer shell 1. In order to ensure that the outer conductor 2 and the outer shell 1 can withstand a certain axial separation force, the limiting flange 22 and the limiting groove 12 can be formed in a full-circle manner and the limiting flange 22 and the limiting groove 12 can be interference fit, thereby ensuring that the outer conductor 2 and the outer shell 1 can withstand an axial separation force of more than thirty pounds, ensuring that the outer conductor 2 and the outer shell 1 do not separate.
[0034] refer to Figure 1-Figure 3 A sealing flange 23 extends from the outer conductor 2. A first sealing groove 24 is formed between the sealing flange 23 and the retaining flange 22. A first sealing ring 25 is installed in the first sealing groove 24. The first sealing ring 25 is positioned between the outer conductor 2 and the outer shell 1, thereby providing a seal between the outer conductor 2 and the outer shell 1, thereby achieving a waterproof and dustproof effect. The sealing flange 23 provides a certain positional support for the first sealing ring 25, preventing deformation and damage of the first sealing ring 25 during assembly, which could result in poor waterproofing. The sealing flange 23 also facilitates the accurate installation of the first sealing ring 25.
[0035] refer to Figure 1-Figure 3 A second sealing groove 31 is provided on the insulator 3, and a second sealing ring 32 is installed in the second sealing groove 31. The second sealing ring 32 is located between the insulator 3 and the outer conductor 2, thereby providing a seal between the insulator 3 and the outer conductor 2, and achieving a waterproof and dustproof effect.
[0036] refer to Figure 1-Figure 3, a first umbrella hook 41 and a second umbrella hook 42 extend outward from the center needle 4, the first umbrella hook 41 is arranged near the narrower end of the center needle 4 (that is, the right end of the center needle 4), and the second umbrella hook 42 is arranged on the side of the first umbrella hook 41 away from the narrower end of the center needle 4 (that is, the left end of the center needle 4), the diameter of the second umbrella hook 42 is larger than the diameter of the first umbrella hook 41, and the first umbrella hook 41 and the second umbrella hook 42 are coaxial, so that during the insertion process of the center needle 4 when assembling the insulator 3, the first umbrella hook 41 enters the insulator 3 first, and then the second umbrella hook 42 enters the insulator 3. Because the diameter of the second umbrella hook 42 is larger than the diameter of the first umbrella hook 41 and the first umbrella hook 41 and the second umbrella hook 42 are coaxial, the position between the center needle 4 and the insulator 3 is corrected during the insertion process through the first umbrella hook 41 and the second umbrella hook 42, thereby ensuring the coaxiality between the center needle 4 and the insulator 3, and at the same time, it is also beneficial to the waterproof performance of the product. When the center needle 4 and the insulator 3 are assembled and inserted into place, an air cavity 43 exists between the first umbrella hook 41 and the second umbrella hook 42. By controlling the distance between the first umbrella hook 41 and the second umbrella hook 42, the size of the air cavity 43 can be controlled. This structure improves the impedance matching of the product in electrical transmission, greatly reduces the reflection loss of information during transmission, and makes the electrical performance of the product more excellent.
[0037] refer to Figure 1-Figure 3 In order to further improve the overall waterproof and dustproof protection effects of the product, a protective cap 5 is provided on one end of the outer conductor 2, and a third sealing ring 14 is provided between the protective cap 5 and one end of the outer shell 1. A third sealing groove 13 can be opened on one end of the outer shell 1, so that the third sealing ring 14 is installed in the third sealing groove 13, and then the protective cap 5 presses the third sealing ring 14, thereby further improving the overall protection capability of the product.

Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
