When the positioning claws of the socket product are inserted into the insulator 2 and then assembled with the housing, they are fixed. An insulator 2 is fixedly connected inside the plug housing 1. First positioning claws 3 are symmetrically and fixedly connected inside the plug housing 1. After the contact is wire-pressed, it is inserted into the assembled component and fixed by the positioning claws to achieve sealed waterproofing. Jacks 4 are equidistantly arranged inside the plug housing 1. Two first wire sealing bodies 5 are fixedly connected to the bottom end inside the plug housing 1. After the wire sealing body is assembled into the plastic housing, it is fixed by a pressure plate. A first pressure plate 6 is fixedly connected to the bottom end inside the plug housing 1. Second positioning claws 7 are symmetrically and fixedly connected inside the plug housing 1. Signal holes 8 are symmetrically arranged inside the plug housing 1, and each signal hole 8 is located between the corresponding two second positioning claws 7. A second wire sealing body 9 is fixedly connected to the bottom end of the signal hole 8. A second pressure plate 10 is fixedly connected inside the second wire sealing body 9. A first interface sealing ring 11 is fixedly connected inside the plug housing 1. The interface sealing ring is assembled into the housing to achieve end face sealing.

[0024] Furthermore, third positioning claws 13 are symmetrically and fixedly connected inside the socket housing 12. A power pin 14 is arranged on the adjacent side of every two third positioning claws 13. Second sealing rings 15 are symmetrically arranged inside the socket housing 12, and each second sealing ring 15 is movably connected to the power pin 14. A third pressure plate 16 is fixedly connected inside the socket housing 12. A signal pin 17 is arranged inside the socket housing 12. A fourth positioning claw 18 is arranged on the adjacent side of the signal pin 17. A third interface sealing ring 19 is fixedly connected inside the socket housing 12. The interface sealing ring is assembled into the housing to achieve end face sealing. The sealing ring is installed on the contact, and after wire-pressing, it is inserted into the assembled component and fixed by the positioning claws to achieve sealed waterproofing.

[0025] Further, a protective shell 20 is installed on the upper surface of the socket housing 12. The inclined surface plug rod 21 is driven by the protective shell 20. The inclined surface plug rods 21 are symmetrically and fixedly connected to the lower surface of the protective shell 20. The inclined surface plug rods 21 are inserted into the moving slots inside the socket housing 12. A slot 22 is formed inside each inclined surface plug rod 21. The inclined surface slide rod 24 enters the inside of the slot 22 under the influence of the spring 26, thereby completing the locking of the protective shell 20. The sliding sleeves 23 are symmetrically and fixedly connected to the inside of the socket housing 12. The inclined surface slide rod 24 is slidably connected to the inside of each sliding sleeve 23. The inclined surface slide rod 24 drives the limiting ring 25 to move. The limiting rings 25 are fixedly connected to the outer surface of each inclined surface slide rod 24. The limiting ring 25 drives the inclined surface slide rod 24 to slide inside the sliding sleeve 23. The springs 26 are fixedly connected to the outer surface of each limiting ring 25. The springs 26 rebound and reset to drive the limiting ring 25 to move. The other end of each spring 26 away from the limiting ring 25 is fixedly connected to the corresponding sliding sleeve 23. The other end of the inclined surface slide rod 24 is inserted into the inside of the slot 22. The connecting seat 27 is fixedly connected to the upper surface of the socket housing 12. The connecting plate 28 is fixedly connected to the upper surface of the connecting seat 27. The lower surface of the plug housing 1 is fixedly connected to the inside of the connecting plate 28. A moving slot is formed inside the socket housing 12. The outer surface of the inclined surface plug rod 21 is slidably connected to the inside of the moving slot.

[0026] In summary, this connector product has a sealed and waterproof structure, and external water vapor is not allowed to enter the module box, which may affect the normal operation of the whole machine. The socket product structure consists of a socket housing 12, an inlaid nut, a third interface sealing ring, a third positioning claw, a second wire sealing body, a contact, and a third pressing plate; the plug product structure consists of a plug housing 1, an inlaid nut, a first interface sealing ring, a first positioning claw, a second sealing ring, a contact, and a first pressing plate. The plug housing 1, socket housing 2, pressing plate, sealing ring, wire sealing body, and pressing plate are formed by molding. Among them, the housing mold needs to integrally mold the locking nut with plastic coating. The positioning claw of the socket product is installed in the insulator 2 and fixed when assembled with the housing. The wire sealing body is assembled into the plastic housing and fixed by the pressing plate. The interface sealing ring is assembled into the housing to achieve end face sealing. The contact is pressed and then installed into the assembled components and fixed by the positioning claw to achieve sealed waterproofing. The positioning claw of the plug product is installed in the pressing plate and fixed when assembled with the housing. The interface sealing ring is assembled into the housing to achieve end face sealing. The sealing ring is installed on the contact, pressed and then installed into the assembled components and fixed by the positioning claw to achieve sealed waterproofing. The protective shell 20 drives the inclined plug rod 21, and the inclined plug rod 21 is inserted into the movable slot inside the socket housing 12. The inclined plug rod 21 contacts the inclined slide rod 24 and squeezes the inclined slide rod 24. The inclined slide rod 24 drives the limiting ring 25 to move. When the limiting ring 25 moves, it squeezes the spring 26. When the inclined plug rod 21 crosses the inclined slide rod 24 and reaches the bottom of the movable slot, due to the existence of the slot 22, the stress point of the inclined slide rod 24 is released, the spring 26 rebounds and resets and drives the limiting ring 25 to move. The limiting ring 25 drives the inclined slide rod 24 to slide inside the sliding sleeve 23. Affected by the spring 26, the inclined slide rod 24 enters the inside of the slot 22, thereby completing the connection between the protective shell 20 and the socket housing 12.
