DETAILED DESCRIPTION

[0017] The following is a further description of the specific embodiments of the present invention with reference to the accompanying drawings:

[0018] As shown in the figure, a crimp-connection type electrical connector socket structure consists of two parts: a socket and a cable assembly.

[0019] The socket consists of a socket housing 1, an insulating assembly 2, a reed switch assembly 3, and a head nut 4. The insulating assembly 2 is mounted within the socket housing 1, and the reed switch assembly 3 is mounted within the insulating assembly 2. Each reed switch in the reed switch assembly 3 is connected to a cable. The cables corresponding to each reed switch form a wiring harness and pass through the cable assembly to connect to other corresponding devices.

[0020] The head nut 4 is mounted on the outside of the end of the socket housing 1 corresponding to the plug. The head nut 4 is sleeved on the end of the socket housing 1. A limit ring 5 is provided on the outer side of the socket housing 1, and the limit ring 5 is used to limit the head nut 4 axially. The side of the limit ring 5 close to the plug is limited by the stepped surface inside the head nut 4, and the other side of the limit ring 5 is limited by the inner retaining ring 6 on the inner side of the head nut end face. The head nut 4 forms a certain axial stroke on the outside of the socket housing 1. An anti-jump ring 7 and a wave spring 8 are sleeved on the outside of the socket housing 1. The anti-jump ring 7 contacts and cooperates with the inner retaining ring 6. The wave spring 8 is squeezed between the anti-jump ring 7 and the limit ring 5. When the head nut 4 moves axially, it needs to overcome the elastic force of the wave spring 8. A circle of pin holes is provided on the head nut 4, which cooperates with a circle of elastic pins on the outside of the plug housing. After the cooperation is completed, the wave spring 8 is squeezed, and the wave spring 8 can prevent the connection from loosening.

[0021] The end of the socket housing 1 corresponding to the cable assembly is fixedly connected to the cable assembly through the tail nut 9. The cable assembly includes a metal sleeve 10 for the cable to pass through, and the tail nut 9 is installed on the end of the sleeve 10 corresponding to the socket housing 1. The inner wall of the tail nut 9 is provided with a retaining ring groove, and the outer wall of the sleeve 10 is provided with a corresponding retaining ring groove. The tail nut 9 is sleeved on the end of the sleeve 10 and is axially limited by the retaining ring 11 and a pair of retaining ring grooves. The tail nut 9 is axially locked on the sleeve 10 and can only rotate. An internal thread is provided on the inner wall of one end of the tail nut 9, and the internal thread cooperates with the external thread of the end face of the socket housing. A circle of threaded holes 12 is also provided on the outer wall of the tail nut, and a set screw is installed in the threaded hole 12. The sleeve 10 and the socket housing 1 are further locked by the set screw.

[0022] A compression nut 13 is installed at the other end of the sleeve 10. The compression nut 13 is screwed to the end face of the sleeve 10 via an internal thread. A sealing rubber sleeve 14 is installed inside the sleeve 10. The sealing rubber sleeve 14 is a corrugated spiral sleeve made of rubber material. It can deform when compressed. The sealing rubber sleeve 14 is located on the side of the sleeve 10 near the compression nut 13. The wiring harness passes through the sealing rubber sleeve 14. One end of the sealing rubber sleeve 14 is limited by the step surface inside the sleeve 10, and the other end of the sealant 14 is squeezed and fitted with the compression nut 13. A compression ring 15 is installed between the compression nut 13 and the sealing rubber sleeve 14. The outer diameter of the compression ring 15 corresponds to the inner diameter of the sleeve 10. One end of the compression ring 15 fits with the end face of the sealing rubber sleeve 14, and the other end of the compression ring 15 fits with the inner wall of the compression nut 13. When compression nut 13 is rotated and tightened, compression ring 15 compresses sealing sleeve 14, causing it to deform and fill the space between the cable and sleeve 10, squeezing and securing the cable while also creating a seal. A shielding ring 16 is installed between sealing sleeve 14 and the stepped surface within the sleeve. One end of shielding ring 16 engages the end surface of sealing sleeve 14, while the other end is held in place by the stepped surface, improving shielding performance.
