[0028] like Figure 1-4 , Figure 6 and Figure 7 As shown, the pin assembly 12 includes a first pad 121, an insulating slot seat 122 and a pin member 123. The insulating slot seat 122 is fixed on the first pad 121 and the first pad 121 is fixedly connected to the male plug housing 11. The pin member 123 is plugged and fixed on the insulating slot seat 122. The front end of the pin member 123 extends into the interior of the insulating slot seat 122, and the rear end of the pin member 123 extends out of the outside of the first pad 121. The front end of the pin member 123 is a metal guide pin, and the rear end of the pin member 123 is a mounting portion with a wire hole for fixing the conductor of the external circuit. The insulating slot seat 122 is circular and has a circular groove at one end, and the insulating block 222 is inserted into the circular groove. The jack assembly 22 includes a second pad 221, an insulating block 222 and a pin member 223. The insulating block 222 is fixed on the second pad 221. A socket 224 is provided on the insulating block 222 and the socket 224 is matched with the pin member 123. The pin member 223 is fixed on the second pad 221 and the front end of the pin member 223 extends into the socket 224. The first pad 121 and the second pad 221 are both made of insulating materials, and the pin members 123 are arranged in plurality. One end of the cable is torn into a plurality of wiring harnesses and inserted into the interior from the ends away from the male plug housing 11 and the female plug housing 21. The wiring harnesses are fixedly connected to the rear ends of the pin members 123 and the rear ends of the pin members 223 one by one to complete the electrical connection. A sealing block 13 with a hole is embedded in the rear end of the male plug housing 11 . The rear end of the male plug housing 11 is open and threadedly connected with a sealing cover 14 , which facilitates the connection and fixation of the wiring harness with the rear end of the pin member 123 .

[0029] like Figure 1-2 , Figure 6 and Figure 7As shown, the insulating block 222 is plugged into the insulating slot seat 122 and a positioning groove 225 is provided on the outer side edge of the insulating block 222 along the axial direction, and a positioning protrusion 124 is provided on the inner wall of the insulating slot seat 122 to facilitate the precise insertion of the pin member 123 into the socket 224, while avoiding relative rotation damage to the pin member 123 after the insulating block 222 and the insulating slot seat 122 are plugged into each other.

[0030] like Figure 1-4 , Figure 6 and Figure 7 As shown, the outer wall of the insulating slot seat 122 is provided with a snap ring 125 and the second pad 221 is located on the outer side of the insulating block 222 and is fixedly connected with a spring 226. The inner wall of the female plug shell 21 is provided with a snap groove 212. After the side wall of the insulating slot seat 122 is inserted into the annular groove between the female plug shell 21 and the insulating block 222, the snap ring 125 is snapped into the snap groove 212. The snap ring 125 is an arc-shaped protrusion surrounding the insulating slot seat 122. The snap ring 125 has a certain elasticity. After the snap ring 125 is inserted into the annular snap groove 212, the male plug component 1 and the female plug component 2 are pre-fixed together, which can also further improve the sealing performance. The spring 226 abuts against the end face of the insulating slot seat 122, providing a certain buffer while also facilitating the male plug component 1 to be pulled out of the female plug component 2.

[0031] like Figure 8 As shown, a rubber gasket 25 is provided between the second gasket 221 and the edge 231 of the inner shell 23, and wave raised rings 251 are provided on both surfaces of the rubber gasket 25, and wave recessed rings 252 matching the wave raised rings 251 are provided on the surface of the edge 231 and the surface of the second gasket 221, thereby improving the sealing between the second gasket 221 and the edge 231.

[0032] like Figure 1 , Figure 7 As shown, a wire distribution plate 26 is fixedly connected to the interior of the inner shell 23, and a wire distribution hole 261 coaxial with the pin member 123 is provided on the wire distribution plate 26 for separating the wire bundles in the cable one by one to avoid entanglement between the wire bundles. At the same time, the rear end of the inner shell 23 is a conical structure with a through hole, which is sealed after the cable passes through the through hole to further improve the sealing performance.

[0033] like Figure 1 , Figure 5 As shown, the tail of the male plug component 1 and the female plug component 2 are both provided with a locking device 3, and the locking device 3 includes a plate 31 with a central hole, and a locking sleeve 32 coaxial with the central hole is provided on one side of the plate 31, and a locking nut 33 is threadedly connected to the outer side of the locking sleeve 32. When the locking nut 33 is screwed toward the plate 31, the locking sleeve 32 shrinks toward the axis to fix the cable, and at the same time, the locking nut 33 abuts against the rear end face of the male plug shell 11 or the rear end face of the female plug shell 21 to fix the plate 31.

[0034] The locker 3 and the cable are both sealed and connected. If sealant is added, the locker 3 can be omitted, and the tail ends of the male plug housing 11 and the female plug housing 21 can be directly connected to the cable as a whole, thereby improving the sealing performance.

[0035] like Figure 1 , Figure 5 As shown, an outer side of the female plug shell 21 is provided with an outer convex ring 213, and an outer side wall of the male plug shell 11 is provided with a first external thread 111. After the nut sleeve 24 is threadedly connected with the first external thread 111, the nut sleeve 24 abuts against the outer convex ring 213, and a second external thread 214 is provided on the outer side wall of the rear end of the female plug shell 21. A clamping ring 27 is threadedly connected to the second external thread 214. The clamping ring 27 is arranged on the side of the nut sleeve 24 away from the outer convex ring 213. The setting of the clamping ring 27 prevents the nut sleeve 24 from slipping off the male plug shell 11 to improve the seismic resistance.

[0036] In this embodiment, the male plug shell 11 and the inner shell 23 of the female plug component 2 are detachable structures, and sealing measures are also provided at the contact connection parts, such as adding O-rings, etc., and some O-rings or gaskets can also be added to the docking part of the male plug component 1 and the female plug component 2 to increase the sealing performance. This part can be determined according to the situation and will not be described in detail here.

[0037] The working principle of the present invention is: by inserting the pin assembly 12 of the male plug assembly 1 into the interior of the female plug shell 21 and threadedly connected to the outside of the male plug shell 11 through a threaded sleeve, a double-layer wrapping method is used to surround the connecting part of the column assembly and the socket assembly 22, and at the same time, an inner shell 23 is provided to divide the interior of the female plug assembly 2 into a two-layer structure, thereby preventing water vapor from entering from the rear end of the female plug assembly 2, greatly improving the sealing and waterproof properties of the connector, avoiding poor contact, facilitating plugging and unplugging operations and subsequent maintenance, and being suitable for outdoor use in severe weather.
