[0002] An automotive connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: it bridges the communication between a blocked or isolated circuit in a circuit, enabling current to flow and the circuit to achieve its intended function.

[0009] Preferably, the size of the conductive cylinder is adapted to that of the conductive core, and both the conductive cylinder and the conductive core are cylindrical structures made of metal copper. At the same time, the conductive core is plugged into the conductive cylinder.
[0010] Preferably, an annular groove is formed on the outer surface of the female connector base, and three fixing pieces are evenly arranged along the circumferential position of the outer side of the male connector base. At the same time, clamping seats are fixedly arranged at the ends of the three fixing pieces, and the cross sections of the clamping seats and the groove are both right trapezoids.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] Please refer to Figures 1-4, the present utility model provides a high-voltage connector for new energy vehicles, which includes a female connector base 1. A high-voltage cable is fixedly installed at the end of the female connector base 1, and a positioning seat 12 is fixedly installed on the surface of the female connector base 1 away from the cable. At the same time, a water-proof frame 13 is fixedly arranged on the surface of the positioning seat 12, and a conductive core 14 is fixedly arranged inside the water-proof frame 13. A male connector base 2 is installed on one side of the female connector base 1. The male connector base 2 includes a water-proof seat 23, and a conductive cylinder 24 is fixedly arranged inside the water-proof seat 23. At the same time, a fixing piece 22 is fixedly arranged on the outside of the male connector base 2, and a clamping seat 21 is fixedly arranged at one end of the fixing piece 22 away from the male connector base 2.
[0020] Working principle: When in use, hold the female connector base 1 and the male connector base 2 with both hands respectively. Insert the water-proof groove 231 opened inside the water-proof seat 23 at the end of the male connector base 2 outside the water-proof frame 13, and at the same time insert the conductive cylinder 24 outside the conductive core 14. When the conductive cylinder 24 and the conductive core 14 are connected together and in a conductive state, the outside can conduct a sealing and waterproof work through the docked water-proof seat 23 and water-proof frame 13, which can prevent the conductive cylinder 24 and the conductive core 14 from short-circuiting due to rainwater, and ensure the safety of this high-voltage connector when working in rainy seasons and humid environments. During the docking process of the female connector base 1 and the male connector base 2, at this time, the clamping seats 21 at the bottom of the three groups of fixing pieces 22 on the outside of the male connector base 2 cross over the end face of the female connector base 1, causing the clamping seats 21 to deform. When the clamping seats 21 are clamped inside the clamping grooves 11, at this time, the three groups of clamping seats 21 are all clamped in the annularly arranged clamping grooves 11, completing the conductive docking and fixed installation work between the female connector base 1 and the male connector base 2; during actual operation, to further ensure the waterproof and sealing performance of the connection between the water-proof frame 13 and the water-proof seat 23, a rubber pad can be wrapped outside the water-proof frame 13 to improve the water-proof effect between the water-proof frame 13 and the water-proof seat 23; to further improve the connection stability between the female connector base 1 and the male connector base 2, through holes can be opened on the surface of the fixing piece 22, and threaded holes (not shown in the figure) are opened on the outer surface of the female connector base 1. Use fixing bolts to pass through the through holes and be screwed into the threaded holes to complete the fixed locking work between the female connector base 1 and the male connector base 2.
[0021] Both the female connector base 1 and the male connector base 2 are cylindrical, and the diameters of the female connector base 1 and the male connector base 2 are the same.
[0022] As a preferred implementation manner, a water-proof groove 231 is opened inside the water-proof seat 23, and the water-proof groove 231 is adapted to the size of the water-proof frame 13, and at the same time, the water-proof frame 13 is inserted inside the water-proof groove 231.
[0023] The cross-sections of both the water-proof seat 23 and the water-proof frame 13 are regular hexagon structures, and the depth of the water-proof groove 231 opened inside the water-proof seat 23 is equal to the length of the water-proof frame 13. The combination of the water-proof seat 23 and the water-proof frame 13 constitutes a waterproof structure for the conductive core 14 and the conductive cylinder 24.
[0024] As a preferred embodiment, the conductive cylinder 24 is adapted to the size of the conductive core 14, and both the conductive cylinder 24 and the conductive core 14 are cylindrical structures made of metal copper. At the same time, the conductive core 14 is inserted into the inside of the conductive cylinder 24.
[0025] An annular groove 11 is formed on the outer surface of the female connector base 1, and three fixing pieces 22 are evenly arranged along the outer circumferential position of the male connector base 2. At the same time, clamping seats 21 are fixedly arranged at the ends of the three fixing pieces 22, and the cross sections of the clamping seats 21 and the grooves 11 are both right trapezoids.
