[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a camera fast power supply DC head with good sealing performance, comprising a female head 1 and a male head 2, wherein the female head 1 and the male head 2 are spliced ​​and fixed to each other through a mechanical structure.

[0021] During assembly and installation, first align the locking head 202 on the male connector 2 with the limiting groove 102 on the female connector 1. After inserting the plug 201 into the wiring port 101, rotate the male connector 2 so that the locking head 202 enters the locking groove 103 to fix the position of the male connector 2. At this time, the wall of the small sealing rubber ring 203 and the large sealing rubber ring 104 are combined with each other to form a complete closed structure.

[0022] Specifically, the female connector 1 includes a wiring port 101, a limiting groove 102, a locking groove 103 and a large sealing rubber ring 104. The wiring port 101 is a cylindrical hole arranged on the central axis of the female connector 1, with a vertical pin built in. The limiting groove 102 is a long rectangular through groove structure arranged on both sides of the wiring port 101. The locking groove 103 is a circular groove structure arranged on the inner wall of the wiring port 101. The limiting groove 102 and the locking groove 103 are connected to each other, and the large sealing rubber ring 104 is fitted on the top of the wiring port 101.

[0023] Specifically, the male connector 2 includes a plug 201, a locking head 202, a small sealing rubber ring 203 and an external wire 204. The plug 201 is a cylindrical plug structure with a cylindrical groove on the central axis. The locking head 202 is a protruding structure arranged on both sides of the top of the plug 201. The small sealing rubber ring 203 is arranged at the end of the plug 201. The external wire 204 is a wire connection structure arranged below the small sealing rubber ring 203.

[0024] Specifically, the diameter of the locking head 202 matches the width of the limiting groove 102 and the locking groove 103 , so that the locking head 202 can move in the limiting groove 102 and the locking groove 103 .
