The first body 11 is penetrated by a plurality of plug-in cavities 101 extending forward and backward; the first waterproof ring 12 is provided in a plurality, each of which is embedded in a corresponding plug-in cavity 101 and extends out of the inner wall of the plug-in cavity 101; the first terminal group 13 includes a plurality of first terminals 131, each of which extends from the back to the front into the corresponding plug-in cavity 101. The waterproof adhesive layer 14 is provided at the rear end of the first body 11 and seals the connection between the first terminal 131 and the rear end of the plug-in cavity 101. The waterproof adhesive layer 14 is used to prevent external moisture from entering the interior of the first body 11 from the connection between the first terminal 131 and the plug-in cavity 101.

[0039] In this embodiment, a convex portion 111 is provided on the first body 11; a first inclined surface 112 is provided on the side of the convex portion 111 facing the male head 20. The waterproof adhesive layer 14 is made of epoxy resin. A first fool-proof portion 113 is convexly provided on the side wall of a part of the plug-in cavity 101. The plug-in cavity 101 is arranged in two layers, upper and lower, and correspondingly, the first waterproof ring 12 is also arranged in two layers, and the first waterproof rings 12 of the upper and lower layers are arranged in a front-to-back staggered manner; when the two first waterproof rings 12 corresponding to the upper and lower layers are installed in the corresponding upper and lower plug-in cavities 101, the front-to-back staggered arrangement of the first waterproof rings 12 in the two layers can avoid opening a groove for installing the first waterproof ring 12 at the same position on the common side wall of the upper and lower plug-in cavities 101, thereby ensuring the structural strength of the first body 11.

[0040] The male connector 20 includes a second body 21, a second terminal group 22, a wire group 23 and a second waterproof ring 24; the plug-in end of the second body 21 integrally extends with a plurality of plug-in parts 211, each plug-in part 211 is inserted into the corresponding plug-in cavity 101 and is pressed and contacted with the corresponding first waterproof ring 12, thereby achieving a waterproof seal at the connection between the plug-in part 211 and the plug-in cavity 101, and preventing external moisture from entering the plug-in part of the male connector 20 and the female socket 10. The arrangement of the plurality of plug-in parts 211 and the plurality of plug-in cavities 101 ensures that even if moisture enters a certain plug-in cavity 101, it will not affect the transmission process in other plug-in cavities 101. Each plug-in part 211 is penetrated by a mounting cavity 201 extending forward and backward, and the welding end of the second body 21 is provided with a mounting groove 202 inwardly concavely connected to the mounting cavity 201. The second terminal group 22 includes a plurality of second terminals 221 that match the first terminals 131, and each second terminal 221 is installed in the corresponding installation cavity 201; the wire group 23 is arranged in the installation groove 202, and the wire group 23 includes a plurality of wires 231 that are welded to the corresponding second terminals 221. The second waterproof ring 24 is arranged in the installation groove 202 and is squeezed and matched with the inner wall of the installation groove 202. The wire group 23 is embedded in the second waterproof ring 24 and extends outward from the second waterproof ring 24. The waterproof ring 24 is used to prevent external moisture from entering the second body 21 from the welding end of the second body 21, further ensuring its waterproof performance.

[0041] In this embodiment, an elastic arm 212 is provided on the second body 21, and a buckle 213 cooperating with the convex part 111 is integrally provided on the free end of the elastic arm 212, so that when the male connector 20 is plugged into the female socket 10, the buckle 213 on the elastic part 212 cooperates with the convex part 111 to lock the male connector 20 and the female socket 10 together, thereby preventing the female socket 10 and the male connector 20 from falling off during the transmission process. The buckle 213 is provided with a second inclined surface 214 cooperating with the first inclined surface 112 on the side facing the female socket 10, and the buckle 213 and the convex part 111 are conveniently locked during the plugging process through the cooperation between the first inclined surface 112 and the second inclined surface 214. The outer end of the part of the plug-in portion 211 is provided with a second fool-proof portion 215 that cooperates with the first fool-proof portion 113; the cooperation between the second fool-proof portion 215 and the first fool-proof portion 113 prevents the reverse insertion of the female socket 10 and the male plug 20 during the plug-in process, and the user experience is better. The second waterproof ring 24 is integrally provided with an annular sealing ring 241 protruding outwardly, and the sealing ring 241 is arranged in three pieces at intervals in the front and back.
