It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] like Figure 1 , Figure 2 As shown, a power connector includes a connector body, the connector body includes a shell 1, a pin 2 is arranged in the shell 1, an annular groove 21 is arranged on the pin 2, a first annular protrusion 11 is arranged in the shell 1, at least a part of the first annular protrusion 11 extends into the annular groove 21, so that a detachable connection between the pin 2 and the shell 1 is realized, and the pin 2 can be taken out from the shell 1 without destroying the structure of the entire power connector, which is convenient for maintenance and replacement, reduces maintenance costs, and improves the maintainability and flexibility of the power connector.

[0031] like Figure 1 , Figure 2 As shown, in the present embodiment, the thickness of the first annular latching protrusion 11 gradually decreases along the depth direction of the annular latching groove 21, so that during disassembly, as the pin 2 is gradually pulled out of the shell 1, the first annular latching protrusion 11 can be deformed, which helps the pin 2 to smoothly detach from the shell 1, thereby reducing the force required for disassembly and reducing the risk of damage caused by disassembly.

[0032] like Figures 1 to 3 , Figure 5 As shown, in this embodiment, the pin 2 extends outward to form a first pin 24 protrusion and a second pin 25 protrusion, and the first pin 24 protrusion and the second pin 25 protrusion are arranged at intervals to form an annular clamping groove 21, which provides convenience for subsequent assembly or maintenance processes. In addition, a second annular clamping protrusion 12 is arranged on one side of the first annular clamping protrusion 11 in the housing 1, and the first annular clamping protrusion 11 is clamped with the first pin 24 protrusion, and the second annular clamping protrusion 12 is clamped with the second pin 25 protrusion, which improves the stability of the connection between the pin 2 and the housing 1 and can limit the pin 2.

[0033] like Figure 2 As shown, in this embodiment, the thickness of the second annular clamping protrusion 12 is less than the thickness of the convex part of the second plug pin 25. When the plug pin 2 is disassembled, the second annular clamping protrusion 12 can be deformed to reduce the resistance during disassembly, so that the plug pin 2 can be more smoothly separated from the housing 1, thereby improving the maintenance efficiency and replacement efficiency of the power connector. In addition, there is a gap between the second annular clamping protrusion 12 and the annular clamping groove 21, which can provide deformation space for the first annular clamping protrusion 11 and the second annular clamping protrusion 12, so as to facilitate the rapid disassembly of the plug pin 2 from the housing 1.

The first arc surface 111 is arranged at an angle. The first arc surface 111 can guide the plug pin 2 to be smoothly inserted into the housing 1, effectively reducing the resistance during insertion, so that the plug pin 2 can be quickly and accurately positioned to the predetermined position, thereby improving the assembly efficiency. In addition, the second arc surface 112 contacts the bottom surface of the annular clamping groove 21, and the flat surface contacts the convex part of the first plug pin 24, thereby limiting the plug pin 2 and preventing the plug pin 2 from shaking or shifting in the housing 1.
