[0039] The technical solution of the present invention will be clearly described below in conjunction with the accompanying drawings. Obviously, the described embodiments are not all embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] It should be noted that the terms "center", "up", "down", "horizontal", "left", "right", "front", "back", "lateral", "longitudinal", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] Combine Figures 1-4 As shown, the present invention provides a terminal assembly 1 , comprising a contact 4 , a shielding member 3 connected to the contact 4 , a cable assembly 5 disposed within the contact 4 and the shielding member 3 , and an insulating member 6 .

[0042] The front end of the shielding member 3 is sleeved on the rear end of the contact 4, the front end of the cable assembly 5 is wrapped inside the head of the contact 4, and the rear end of the cable assembly 5 is exposed outside the shielding member 3. The front end of the insulating member 6 is sleeved inside the contact 4, and the rear end is connected to the front end of the shielding member 3.

[0043] The contact 4, the main conductive portion of the terminal assembly, is used to establish an electrical connection with an external device or circuit. The shield 3 provides electromagnetic shielding, protecting the cable assembly 5 from external electromagnetic interference while ensuring stable electrical performance of the terminal assembly. The cable assembly 5 acts as a signal transmission medium, transmitting external signals to the internal circuit or device through the contact 4. The insulator 6 provides electrical insulation, ensuring electrical isolation between the contact 4 and the shield 3 to prevent short circuits or electrical interference.

[0044] A support ring 2 is coaxially arranged inside the shielding member 3 , and the shielding member 3 and the support ring 2 are connected after being abutted by an abutting structure.

[0045] The support ring 2 provides additional support and stability for the shielding member 3 , ensuring the coaxiality and position accuracy between the shielding member 3 and the contact member 4 .

[0046] Combine Figure 6-Figure 8 As shown, at least one fixed stop 31 is provided at the rear end of the shielding member 3. The fixed stop 31 comprises a flat portion 31b at the front and an inclined portion 31a at the rear. The fixed stop 31 is used to provide abutment with the tilted protrusion 21 of the support ring 2, thereby ensuring a stable connection between the shielding member 3 and the support ring 2 and preventing the support ring 2 from moving in the axial direction.

[0047] The inclined portion 31a is inclined downward from the back to the front, the top of the inclined portion 31a is connected to the outer wall 32 of the shielding member, the bottom of the inclined portion 31a is connected to the rear end of the flat portion 31b, and a gap is left between the front end of the flat portion 31b and the inner wall close to the shielding member 3 to ensure the flexibility or elasticity of the fixed stop block 31.

[0048] The flat portion 31b is an arc-shaped structure.

[0049] The top surface of the flat portion 31 b is located within the curved surface of the inner wall 33 of the shielding element.

[0050] like Figure 5 As shown, the tail end of the support ring 2 is provided with at least one tilting 21, the number and position of the tilting 21 are adapted to the number and position of the fixed stop block 31. The support ring 2 has a support ring outer wall 23, a support ring inner wall 24 and a support ring rear end face 22.

[0051] like Figure 9 As shown, in a specific embodiment, the protrusion 21 is provided on the rear end surface 22 of the support ring, wherein the front end of the protrusion 21 is connected to the rear end surface 22 of the support ring, and the rear end of the protrusion 21 is higher than the outer wall 23 of the support ring. This design enables the protrusion 21 to form an effective abutment with the fixed stop block 31 in the axial direction.

[0052] like Figure 10 As shown, in a specific embodiment, the tilting 21 is provided on the outer wall 23 of the support ring, the front end of the tilting 21 is connected to the outer wall 23 of the support ring, and the rear end of the tilting 21 is higher than the outer wall 23 of the support ring. A gap is left between the rear end of the tilting 21 and the support ring 2.

[0053] Combine Figure 1 、 Figure 3 、 Figure 5 As shown, the protrusion 21 of the support ring 2 abuts against the fixed stop block 31 of the shielding member 3 on the axis, the protrusion 21 and the fixed stop block 31 form an abutting structure, and the bottom wall of the protrusion 21 abuts against the front end of the fixed stop block 31, so that the support ring 2 is tightly connected to the contact member 4, thereby ensuring a stable connection between the support ring 2 and the shielding member 3.

[0054] The angle between the bottom of the tilting 21 and the axis of the support ring 2 is 0°-180°.

[0055] When the tilting part 21 is not assembled, it is formed on the support ring 2 by stamping. This forming method not only ensures the structural stability and precision of the tilting part 21, but also improves production efficiency.

[0056] Combine Figures 11-17 As shown, the cable assembly 5 includes an inner contact 51, a cable 52 connected to the inner contact 51, a coaxial cable 53 sleeved on the cable 52, and a shielding braid 54 sleeved on the coaxial cable 53. The shielding braid 54 includes a first shielding braid section 54a and a second shielding braid section 54b, and the second shielding braid section 54b is flipped and connected to the outside of the first shielding braid section 54a.

[0057] The cable assembly 5 is a crucial component of the terminal assembly, responsible for signal transmission and electrical connection. The inner contact 51 serves as the conductive core of the cable assembly 5, transmitting signals from the cable to the rest of the terminal assembly, or vice versa.

[0058] Cable 52 is the signal transmission medium. Coaxial cable 53 is sleeved over cable 52, further enhancing signal transmission and providing additional electromagnetic shielding. Shielding braid 54 is a key component of coaxial cable 53, providing additional electromagnetic shielding to protect the signal from external electromagnetic interference.

[0059] The main body of the support ring 2 is embedded between the shielding braided section 1 54a and the shielding braided section 2 54b.

[0060] The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the needs of different situations.

[0061] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
