[0019] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0020] An embodiment of the present application discloses an electrical connector with a reinforced bayonet connection. Referring to Figure 1 and Figure 2 , it includes a male socket head 1 and a female socket head 2. The end of the male socket head 1 is provided with a pin 11, and the end of the female socket head 2 is provided with a pin socket that cooperates with the pin 11. The male socket head 1 and the female socket head 2 are inserted and connected in alignment. A clamping ring 3 is coaxially and slidably sleeved outside the male socket head 1. A clamping portion 4 is provided at the end of the clamping ring 3 close to the female socket head 2. The clamping portion 4 is clamped and connected to the female socket head 2. A second limiting member is also provided outside the male socket head 1 to limit the sliding of the clamping ring 3 on the male socket head 1, which plays a secondary guarantee effect on the connection between the male socket head 1 and the female socket head 2.

[0021] Specifically, the clamping portion 4 includes an integrally fixed elastic portion 41. One end of the elastic portion 41 is fixedly connected to the clamping ring 3, and one end extends toward the female socket head 2 to form a hook portion 42 that bends toward the axis of the female socket head 2. An operating piece 44 is integrally fixed on the elastic portion 41. A fulcrum portion 43 that protrudes in the direction away from the male socket head 1 is formed on the operating piece 44. The operating piece 44 extends from the hook portion 42 to the side away from the female socket head 2 and passes through the fulcrum portion 43. The operator presses the side of the fulcrum portion 43 on the operating piece 44 away from the hook portion 42 downward against the male socket head 1, so that the operating piece 44 pivots the hook portion away from the female socket head 2 with the fulcrum portion 43 as the fulcrum. A connecting ring 21 for cooperating with the hook portion 42 is protrudingly provided on the outer wall of the female socket head 2. By moving the clamping ring 3 to the position on the male socket head 1 closest to the female socket head 2 and inserting the female socket head 2 into the male socket head 1, the hook portion 42 of the clamping portion 4 is located on the side of the connecting ring 21 away from the male socket head 1, and the connecting ring 21 is hooked by the hook portion 42 to limit the separation of the male socket head 1 and the female socket head 2.

[0022] In the embodiment of the present application, the second limiting member includes a limiting ring 5. The limiting ring 5 is coaxially sleeved outside the male socket head 1 and is located on the side of the clamping ring 3 away from the female socket head 2. An external thread 13 is provided on the outer wall of the male socket head 1, and the limiting ring 5 is threadedly connected to the external thread 13 of the male socket head 1. By rotating the limiting ring 5, the limiting ring 5 can be moved on the male socket head 1. When the clamping portion 4 on the clamping ring 3 is connected to the female socket head 2, the limiting ring 5 is rotated to abut against the clamping ring 3, which can effectively prevent the clamping ring 3 from retracting and plays a role in strengthening and guaranteeing the connection between the male socket head 1 and the female socket head 2.

[0023] First anti-slip protrusions 51 can also be designed on the outer wall of the limiting ring 5 to facilitate the operator to rotate the limiting ring 5. Second anti-slip protrusions 45 can also be designed on the outer wall of the operating piece 44 to prevent the operator from slipping during the process of pressing down the operating piece 44.

[0024] Furthermore, a guiding inclined surface 22 is provided at the end face edge of the connecting ring 21 facing the male socket head 1. Through the design of the guiding inclined surface 22, when the clamping ring 3 moves towards the female socket head 2 to connect the clamping portion 4 with the female socket head 2, the clamping portion 4 automatically expands outwards under the guiding action of the guiding inclined surface 22, enabling the clamping portion 4 to smoothly connect with the connecting ring 21 of the female socket head 2. At the same time, through the design of the clamping portion 4, after the male socket head 1 and the female socket head 2 are inserted, the operator can also directly rotate the limiting ring 5 to push the clamping ring 3 to move to connect with the female socket head 2, improving the connection efficiency between the male socket head 1 and the female socket head 2.

[0025] In the embodiment of the present application, a gap for the external thread 13 to pass through is provided between the clamping ring 3 and the outer wall of the male socket head 1, enabling the clamping ring 3 to smoothly slide on the male socket head 1. Furthermore, a guiding groove 12 is axially provided on the outer wall of the male socket head 1 along its own axis. The inner ring cross-section of the clamping ring 3 is designed in a shape that matches the guiding groove 12. By the sliding fit between the clamping ring 3 and the guiding groove 12, the rotation of the clamping ring 3 can be restricted and the width change of the gap between the clamping ring 3 and the outer wall of the male socket head 1 can be restricted, avoiding friction between the clamping ring 3 and the external thread 13 on the outer wall of the male socket head 1.

[0026] Furthermore, a connecting groove 14 is coaxially provided in a circle on the end face of the male socket head 1 outside the pin 11. A plugging ring 23 is integrally and fixedly provided coaxially on the end face of the female socket head 2. A ring groove is coaxially provided on the inner wall of the connecting groove 14, and a sealing rubber ring 15 is embedded in the ring groove. When the male socket head 1 and the female socket head 2 are connected to each other, the plugging ring 23 is aligned and inserted into the connecting groove 14, and the plugging ring 23 is in close contact with the sealing rubber ring 15, effectively waterproofing the pin 11 and the pin socket.
