[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Combination Figure 1 to Figure 2 A waterproof connector shown in the figure comprises a socket 1 and a plug 2, wherein a socket 1 is provided with a socket slot 3, a plurality of conductive holes 4 are provided at the bottom of the socket slot 3, a waterproof sleeve structure 5 is fixedly provided at one end of the socket 1, a plurality of conductive terminals 6 matching with the conductive holes 4 are fixedly provided at one end of the plug 2, a rubber sealing ring 7 is provided at the connection between the conductive terminals 6 and the plug 2, electric telescopic rods 8 are provided on both sides of the outside of the plug 2, and a rotating fixing structure 9 is provided at the other end of the plug 2.

[0019] The waterproof sleeve structure 5 comprises a waterproof sleeve 51 , an inner thread ring 52 is provided at the top of the inner wall of the waterproof sleeve 51 , and a socket 53 matching with the electric telescopic rod 8 is provided on the inner wall of the waterproof sleeve 51 for fixing the plug.

[0020] The rotating fixing structure 9 includes a connecting column 91, which is rotatably connected to the bottom of the plug 2 through a bearing. An external thread ring 92 is provided on the outside of the connecting column 91. The external thread ring 92 is meshed with the internal thread 52 to completely fix the plug 2 in the waterproof sleeve 51 for protection and enhanced protection. A base 93 is fixedly provided at the bottom of the connecting column 91, and a waterproof sealing layer 94 is provided at the connection between the base 93 and the connecting column 91.

[0021] The waterproof sealing layer 94 is composed of a water-blocking yarn, which is wrapped around a water-absorbing resin. The water-absorbing resin absorbs water vapor to prevent water vapor from entering the interior from the connection with the base 93. The water-blocking yarn is covered with a silicone rubber sealing material to enhance the sealing effect.

[0022] The exteriors of the socket 1, the waterproof sleeve 51 and the base 93 are all coated with waterproof and corrosion-resistant materials.

[0023] Working principle: When in use, first insert the conductive terminal into the conductive hole through the plug-in slot, and then rotate the base, the base will drive the connecting column to rotate, and the external threaded ring on the outside of the connecting column and the internal threaded ring of the waterproof sleeve will engage with each other through rotation to tightly fix the entire plug inside the waterproof sleeve. At this time, the base fits with the bottom of the waterproof sleeve, and the waterproof layer can block and absorb external water vapor to prevent water vapor from entering the interior from the connection between the base and the bottom of the waterproof sleeve. Secondly, the silicone rubber sealing material can enhance the sealing effect. After fixation, the electric telescopic rod extends out and engages with the jack to further fix the plug and enhance stability. At this time, the rubber sealing ring at the connection between the conductive terminal and the plug is closed at the notch of the plug-in slot to prevent water vapor from penetrating into the plug-in slot, further enhancing the waterproof sealing effect.
