BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural diagram of the present utility model.

[0015] In the figure: seat shell 1, insulation component 2, pin assembly 3, cable sleeve 4, cable cover 5, tail nut 6, retaining ring 7, waterproof sealing ring 8, pressing piece 9, limit ring 10, O-ring 11, waterproof rubber plug 12, and wire clamping plate 13. DETAILED DESCRIPTION

[0016] The following is a further description of the specific embodiments of the present invention with reference to the accompanying drawings:

[0017] like Figure 1Figure 1 shows a circular electrical connector socket structure consisting of a socket body and a cable accessory connected to the socket body. The socket body includes a housing 1, within which is mounted an insulating assembly 2, which houses a pin assembly 3. One end of the pin assembly 3 is electrically connected to the reed switch assembly within the electrical connector plug. The housing 1, on the end opposite the plug, is fixedly connected via crimping. The other end of the pin assembly 3 is connected to a cable, which comprises a wiring harness consisting of multiple signal and power lines. The wiring harness passes through the cable accessory, which secures, seals, and shields the harness.

[0018] The cable accessories consist of two parts: a cable sleeve 4 and a cable cover 5. The cable passes through the cable sleeve 4 and the cable cover 5 and is connected to the device to transmit signals. The cable sleeve 4 is a cylindrical shell. A tail nut 6 is installed on the outside of one end of the cable sleeve 4 connected to the seat shell 1. The tail nut 6 cooperates with the external thread of the corresponding end of the seat shell through its internal thread. A retaining ring groove is provided on the inner wall of the tail nut 6, and a retaining ring 7 is installed in the retaining ring groove. A retaining ring groove is also provided at the corresponding position on the outer wall of the cable sleeve 4. The retaining ring 7 is embedded in a pair of retaining ring grooves, which will axially limit the tail nut 6 on the outer wall of the cable sleeve 4 to prevent the tail nut 6 from axial movement. At the same time, a sealing ring groove is provided on the inner wall of the tail nut 6, and a waterproof sealing ring 8 is installed in the sealing ring groove. The waterproof sealing ring 8 cooperates with the step surface of the end face of the cable sleeve 4 to achieve sealing between the cable sleeve 4 and the seat shell 1.

[0019] The cable cover 5 is installed at the end of the cable sleeve 4 away from the seat housing. The cable cover 5 is mated with the end of the cable sleeve 4 through its internal threads. To improve the stability of the connection, the end of the cable sleeve 4 is designed as a multi-stage annular step surface. The diameter of the step surface gradually decreases toward the end, and the slope transition between adjacent step surfaces is formed. A clamping member 9 is sleeved on the step surface. The clamping member 9 is made of rubber. The inner wall of the clamping member 9 is a conical surface that matches the multi-stage step surface at the end of the cable sleeve 4. The outer wall of the clamping member 9 is squeezed and fitted with the inner wall of the cable cover 5. When the cable cover 5 is screwed together with the cable sleeve 4, the clamping member 9 is squeezed into the conical space formed between the multi-stage step surface and the inner wall of the cable cover 5, filling the space and achieving the purpose of sealing.

[0020] To limit the position of the cable cover 5, a raised retaining ring 10 is installed on the outside of the middle of the cable sleeve 4. A sealing groove is installed on the side of the retaining ring 10 near the cable cover 5. An O-ring 11 is installed in the sealing groove, which limits and seals the end face of the cable cover 5. At the same time, a retaining groove is provided in the inner cavity of the cable cover 5, and a waterproof rubber plug 12 is installed in the retaining groove. The central portion of the waterproof rubber plug 12 has a cable hole for mating with the cable. One end of the waterproof rubber plug 12 mates with the end face of the cable sleeve 4 and the outer end face of the compression member 9. The cable passes through the waterproof rubber plug 12, which seals the outer wall of the cable.

[0021] In order to avoid the connection failure caused by swinging of the protruding end of the cable, a pair of wire clamping plates 13 extend outward from the end surface of the cable cover away from the cable sleeve. The pair of wire clamping plates 13 are distributed up and down and are located on the vertical center plane of the cable cover 5. A connecting hole is provided in the center of the pair of wire clamping plates 13. The cable and the cable cover 5 can be fixed by cooperating with a pair of arc-shaped clamping plates distributed on both sides of the wire clamping plates.
