[0007] Preferably, an interference fit is achieved between the second insulating sleeve and the shell body through a pressure ring so as to achieve fixed installation.

[0008] Preferably, a portion of the center needle is also placed in the second insulating sleeve.

[0009] Preferably, a center needle tail needle extends from one end of the center needle near the end of the first insulating sleeve, and the center needle tail needle is placed outside the shell body, and the side of the center needle and the outer circle opposite to the center needle tail needle are concave.

[0010] Preferably, the hoop has a certain elasticity, and the hoop shrinks axially to clamp the first insulating sleeve.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0018] Reference Figure 1 to Figure 2 , a high-definition data and image transmission connector that prevents rotation, comprising a shell body 1, a first insulating sleeve 2 placed in the shell body and supported by a groove in the shell body, a center needle 3 placed in an inner hole of the first insulating sleeve, and a second insulating sleeve 4 placed in the shell body 1 and supported by one end of the first insulating sleeve;

[0019] In order to limit the installation of the second insulating sleeve 2, a pressure ring 5 is further provided between the second insulating sleeve 2 and the shell body 1, and an interference fit is achieved between the second insulating sleeve 2 and the shell body 1 through the pressure ring 5, so as to achieve fixed installation;

[0020] In order to ensure the installation between the center needle 3 and the second insulating sleeve 4 and prevent rotation after assembly, a hoop 6 is provided on the outside of the second insulating sleeve 4 in an interference fit;

[0021] The side edge of the part of the center needle 3 placed in the second insulating sleeve 4 is provided with a serration 31, which is convenient for tight fit with the first insulating sleeve and can prevent rotation. A part of the center needle 3 is also placed in the second insulating sleeve 2;

[0022] A center needle tail needle 32 extends from one end of the center needle 3 near the end of the first insulating sleeve 2, and the center needle tail needle 32 is placed outside the shell body 1;

[0023] The side edge of the center needle 3 and the outer circle opposite to the center needle tail needle 32 are punched with concave points 33 to prevent the two from rotating relative to each other;

[0024] The hoop ring 6 is of convex structure, and an installation groove 61 similar to the first insulating sleeve is opened at the end. The outer wall of the end of the hoop ring 6 is inclined inward, and the hoop ring 6 has a certain elasticity. The hoop ring 6 axially contracts and clamps the first insulating sleeve 2, so that the inside is fixed and not loose, thereby improving the stability and reliability of the product.

[0025] In this implementation case, the center needle 3 is placed in the inner hole of the first insulating sleeve 4, and the accessories are assembled. The assembly is placed, the hoop 6 is put on the assembly, and the outer shell body 1 is press-fitted to assemble into a second group of components. The second insulator is then placed in the outer shell body 1 of the second group of components and press-fitted with the pressing ring 5. Finally, it is placed on the jig, and the center needle is bent to form a tail needle.

[0026] refer to Figure 3 The hoop ring 6 is formed by stamping, and specifically, a strip plate is used. First, the section difference is made, and the large and small outer diameters are punched out, and then the groove is punched out to punch out a notch that can be installed in the shape of the insulator, and finally it is rolled to facilitate the installation of the insulator; the side of the hoop ring 6 is a C-shaped structure. When the first insulating sleeve is installed during the installation, the groove punched by the hoop ring 6 is embedded in the surrounding profiling structure, and the hoop ring 6 is fixed by locking the section 62;

[0027] Compared with the turned hoop, the stamped hoop 6 needs not only turning but also milling to mill out the groove for fitting the first insulating sleeve, and also needs special processing of the material, which consumes a lot of time, has low work efficiency and high cost. In addition, since it is integrated, the dimensions of the four inner walls for fitting the first insulating sleeve need to be accurate, and four groups need to be locked and fixed at the same time during installation.

[0028] The stamped hoop 6 can be formed directly by stamping, which has high work efficiency and low cost. Moreover, since it is C-shaped and has a break, the groove only needs to be suitable for the first insulating sleeve for installation, and there is no need to lock four groups at the same time. After being set on the first insulating sleeve, only the C-shaped port needs to be locked to complete the fixation.

[0029] The benefits of the utility model are that the center pin of the technical solution is embedded in the inner hole of the insulator through the serrations and is not easy to shake, ensuring that the user can maintain stability during mutual mating and plugging; the first insulating sleeve and the inner hole of the shell body are further fixed inside by a hoop, which facilitates the performance stability and reliability of the product. On the one hand, it ensures that the internal structure of the product is stable after assembly and does not loosen after high temperature, and on the other hand, it has excellent electrical performance.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
