Detailed Implementation

[0017] The power connector of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description and claims.

[0018] Please refer to Figures 2 to 4 This embodiment provides a power connector, including a plug 1 and a socket 2; the plug 1 is provided with an elastic positioning pin 3; the socket 2 is provided with a groove 4 that cooperates with the elastic positioning pin 3, so that after the plug 1 and the socket 2 are mated and rotated relative to each other, the elastic positioning pin 3 is embedded in the groove 4 to form a rotation lock and prevent the connector from loosening. The socket 2 has a detachable push button 5 installed on its outer shell. The push button 5 has a top block 6. When the push button 5 slides forward along the outer shell, the top block 6 pushes the elastic positioning pin 3 out of the groove 4 to unlock it. The push button 5 has a snap-fit ​​structure between it and the outer casing, which allows the push button to be quickly installed and removed without tools.

[0019] The power connector's plug-mounted spring-loaded locating pin and socket groove form a dual "rotation + insertion" locking mechanism, providing strong vibration and impact resistance and significantly reducing the risk of accidental loosening due to dragging or shaking. Furthermore, the push button and socket housing are connected using a snap-fit ​​structure, allowing for quick tool-free disassembly. In situations requiring protection against accidental contact by non-professionals (such as rail transit and outdoor base stations), operators can remove the push button after insertion, placing the connector in a unlocked state and fundamentally preventing power outages caused by misoperation.

[0020] Specifically, in this embodiment, the elastic positioning pin 3 is a spring pin that extends and retracts radially along the plug 1; the groove 4 is an annular groove or a partially arc-shaped groove, the depth of which matches the extension amount of the elastic positioning pin 3. The plug 1 and the socket 2 are locked by rotating an angle α, where 30°≤α≤120°.

[0021] Please refer to Figures 5 to 8 The push button 5 is equipped with at least two elastic ejector pins 7. When the push button 5 is installed on the socket housing, the elastic ejector pins 7 abut against the housing and keep the top block 6 in the initial position separated from the elastic positioning pin 3, preventing accidental unlocking. The push button 5 is of moderate size and its shape fits the finger, making it easy to push.

[0022] Furthermore, the top of the push button 5 is provided with a guide slope at the front end, which is used to smoothly push the elastic positioning pin 3 out of the groove 4 when the push button moves forward.

[0023] The main body of the push button 5 has a through round hole 8 for threading a key ring or lanyard so that the operator can carry it.

[0024] Please refer to Figures 9 to 11 The push button 5 is connected to the socket housing using a snap-fit ​​structure, which includes: A protruding buckle 9 is provided on the side wall of the push button; A corresponding recess 10 is provided on the side wall of the socket housing; The protruding buckle 9 and the recessed buckle 10 engage elastically when the push button slides into the socket housing, and disengage when a reverse pulling force is applied, thus enabling tool-free disassembly of the push button.

[0025] A limiting structure is provided between the push button and the socket housing to limit the sliding stroke of the push button and prevent it from moving too far forward or falling off. This limiting structure is integrally formed with the socket housing, and its structure matches the bottom structure of the push button 5. It has a first cavity 11 for accommodating the top block 6 of the push button 5, and a second cavity 12 for accommodating the two elastic ejector pins 7. The front end of the first cavity 11 is open to facilitate the extension of the top block 6. When the push button 5 is installed in the socket housing, the elastic ejector pins 7 abut against the inner wall of the second cavity 12, keeping the top block 6 in its initial position separated from the elastic positioning pin 3.

[0026] The socket in this embodiment is either a wire-end socket or a board-end socket, and both structures have the same fixed anti-loosening structure and a detachable push-button unlocking mechanism.

[0027] Please refer to Figure 12 and 13 In this embodiment, there are two types of power connectors, both of which have the same fixed anti-loosening structure and detachable push-button unlocking mechanism.

[0028] In summary, the power connector in this embodiment integrates the three major functions of locking, unlocking, and preventing accidental contact into three parts: the plug positioning pin, the socket groove, and the detachable push button. This reduces the need for additional accessories such as locking wires, fuses, and lead seals, thereby lowering the overall cost and size of the device. It also facilitates mass production and on-site maintenance.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
