In practice, the number and arrangement of the metal pins 212 can be set according to actual needs, but must correspond to the female metal holes 19 within the female connector 1.

[0041] In this embodiment, the end of the metal needle 212 is arranged inside the male plug rubber head 214. When the male plug 2 and the female plug 1 are plugged in, the male plug rubber head 214 is pushed, and the male plug rubber head 214 pushes the spring 215 inward. At the same time, the metal needle 212 is exposed, so that it can be plugged in with the female metal hole 19 in the female plug 1.

[0042] The present invention can achieve overall waterproofing when the male connector 2 and the female connector 1 are plugged in or unplugged in shallow water or when powered on. The front end of the locking ring 23 is provided with a petal-type locking ring buckle 24, and the front end of the female connector socket housing 11 is provided with a "V"-shaped snap ring groove 12. After the male connector 2 and the female connector 1 are plugged in, the push ring 26 is pushed forward, and the petal-type locking ring buckle 24 of the locking ring 23 is tightened and snapped into the "V"-shaped snap ring groove 12 at the front end of the female connector socket housing 11, thereby locking the male connector 2 and the female connector 1. The push ring 26 is pushed backward, and the petal-type locking ring buckle 24 of the locking ring 23 is opened and disengaged from the "V"-shaped snap ring groove 12 at the front end of the female connector socket housing 11, thereby separating the male connector 2 and the female connector 1.

[0043] In this embodiment, the outer side surfaces of the female socket rubber head 17 and the male plug rubber head 214 (i.e., the surface where the female socket rubber head 17 and the male plug rubber head 214 contact each other) are in the shape of an outwardly protruding arc surface. When the male connector 2 and the female connector 1 are plugged into each other, the arc surfaces of the female socket rubber head 17 and the male plug rubber head 214 fit together, water is discharged outward from both sides, the bellows 216 and the spring 215 are compressed and deformed, the male plug rubber head 214 slides backward, and the metal needle 212 is exposed and inserted into the female metal hole 19, thereby conducting with it. The metal needle plastic insert 213 is located in the middle of the contact surface between the female socket rubber head 17 and the male plug rubber head 214, thereby ensuring that the metal needle 212 is completely isolated from water.

[0044] When the male connector 2 and the female connector 1 are plugged in, water is discharged from above the waterproof rubber pad 16 of the female connector socket. After the plug is inserted to the bottom, the male connector front body 6 presses the waterproof rubber pad 16 of the female connector socket, causing it to deform and isolate water from entering.

[0045] The utility model is mainly used in shallow water (1 to 2 meters deep), on equipment working underwater or outdoors in an environment with heavy rain and water accumulation, and can be plugged in and out while ensuring that it is in a charged state.
