Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The diagram shows a latching power connector, comprising a male plug 1 and a female socket 7. A plastic partition 9 is fixedly connected to the connection end of the male plug 1. The plastic partition 9 effectively prevents interference between the power terminals 8 and the signal terminals 10 of the female socket, ensuring the independence and stability of power signals and other signal transmissions, and avoiding equipment malfunctions caused by signal crosstalk. The male plug 1 has a pair of power terminals 8 for power transmission, providing a stable power supply to the equipment. The male plug 1 also has multiple female socket signal terminals 10 for transmitting various control and data signals, enabling information exchange between devices. A locking assembly is located on the outer side of the male plug 1. The locking assembly includes a fixing frame 2 fixedly connected to the outer side of the male plug 1. The fixing frame 2 provides the mounting base and support structure for the locking assembly, ensuring stable installation and reliable operation of all components. A rotating shaft 3 is rotatably connected to the inner wall of the fixing frame 2. The rotating shaft 3 provides support and a rotation axis for the rotation of a locking plate 4, allowing the locking plate 4 to rotate flexibly. The locking plate 4 is located on the outer side of the rotating shaft 3. The locking plate 4 is connected to the fixing frame 2 via a torsion spring. The torsion spring provides a restoring force to the locking plate 4, ensuring that the locking plate 4 can automatically reset after completing the locking action and maintain the stability of the locking state. A locking groove 5 is provided on the outer side of the locking plate 4. The locking groove 5 is used to cooperate with the locking block 6 on the male plug 1 to achieve a firm locking between the male plug 1 and the female socket 7, preventing loosening or falling off during the connection process and ensuring the reliability of the connection. A wire 12 is provided on the outer side of the male plug 1. The wire 12 is used to transmit power and signals and is a key component for connecting the power connector to external devices. An insulating washer 16 is provided at the connection position between the wire 12 and the male plug 1. The insulating washer 16 can effectively prevent leakage and improve the safety of the power connector. At the same time, it can also play a certain sealing role to prevent moisture, dust and other impurities from entering the connection part and affecting the connection performance. A locking block 6 is fixedly connected to the outer side of the male plug 1. The locking block 6 engages with the locking groove 5. Through the cooperation of the locking block 6 and the locking groove 5, the mechanical locking between the male plug 1 and the female socket 7 is achieved, further enhancing the stability and reliability of the connection.

[0023] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a waterproof ring 15 be provided on the outer side of the male plug 1. The waterproof ring 15 effectively prevents moisture and liquid from entering the plug by tightly fitting the contact part between the male plug 1 and the external environment, avoiding safety hazards such as short circuits and leakage caused by liquid entry, ensuring electrical safety, and extending the service life of the plug. One end of the power terminal 8 is provided with an anti-touch finger cap 11, which can prevent fingers from accidentally touching the live power terminal 8, avoiding electric shock accidents and providing safety protection for users. The connection end of the female socket 7 is provided with a pair of spring-loaded power terminals 13, which are adapted to the power terminal 8. Through its own elastic structure, the spring-loaded power terminals 13 can provide stable pressure when connected to the power terminal 8, ensuring tight contact between the two, reducing contact resistance, ensuring the stability and reliability of current transmission, and reducing problems such as overheating and power failure caused by poor contact. The connection end of the female socket 7 is provided with multiple male plug signal terminals 14, which are adapted to the female socket signal terminals 10. The male plug signal terminal 14 and the female socket signal terminal 10 work together to achieve stable signal transmission, ensure accurate data exchange between devices, and guarantee the normal operation of electronic equipment.

[0024] The working principle of this utility model is as follows: Dragging the male plug 1 aligns the power terminal 8 with the rotating spring power terminal 13. Pressing down one end of the locking plate 4 causes the end of the locking plate 4 with the slot 5 to lift up, connecting the power terminal 8 with the rotating spring power terminal 13. The plastic partition 9 limits the rotation of the rotating spring power terminal 13 and the male plug signal terminal 14, achieving a foolproof effect. The male plug signal terminal 14 is connected to the female socket signal terminal 10. When the male plug 1 and the female socket 7 are connected, the locking plate 4 is released. Under the action of the torsion spring, the locking block 6 engages with the slot 5, strengthening the connection between the male plug 1 and the female socket 7. The waterproof ring 15 enhances the waterproof sealing effect between the male plug 1 and the female socket 7.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
