Technical Field

[0001] This application relates to the field of new energy vehicle charging, and particularly to a charging socket that is convenient for assembly and maintenance. Background Art

[0002] The electric vehicle charging socket is an important part of electric vehicle charging. With the popularization of new energy vehicles and the increasing charging demand, the design of charging sockets is constantly improving. To ensure the safety and reliability of charging sockets, most charging sockets on the market currently adopt the method of connecting internal terminals to wires and fixing them to the PCB board with screws. This connection method not only ensures the durability of the charging socket but also provides a basic guarantee for the vehicle to charge safely.

[0003] When maintenance and troubleshooting are required, special tools are needed for operations such as the screwing of terminals, wires, the PCB board, and screws, as well as the connection of terminals and wires. Moreover, the large number of terminals leads to an even larger number of wires, so the inspection and troubleshooting are rather cumbersome and thus need to be improved.

Detailed Description of the Embodiment

[0030] The following is a further detailed description of the present application in combination with the attached Figures 1-3 drawings.

[0031] An embodiment of the present application provides a charging socket that is convenient for assembly and maintenance. Referring to Figure 1 and Figure 2 , it includes a housing 1. One end inside the housing 1 is snap-connected with a PCB board 2. A metal sleeve 3 is welded on the PCB board 2. One end of the housing 1 away from the PCB board 2 is snap-connected with a plug-in connector 4. A plug-in terminal 5 is snap-connected inside the plug-in connector 4. One end of the plug-in terminal 5 away from the plug-in connector 4 can be inserted into the metal sleeve 3 to realize the conduction between the plug-in terminal 5 and the PCB board 2 through the metal sleeve 3, achieving the effects of simplifying maintenance and quickly replacing the terminal.

[0032] Referring to Figure 2 and Figure 3 , one end of the plug-in connector 4 passes through the housing 1 to protrude to form a plug-in port, and the plug-in port has various structural designs. The multi-hole socket can simultaneously meet more wiring requirements and improve the adaptability range of the socket. A folding cover 12 or a flip cover 12 is provided at the connection part between the plug-in connector 4 and the housing 1. The folding cover 12 realizes the opening and closing operations by using a hinge structure, which is convenient for daily maintenance and use; the flip cover 12 is made of an elastic material and can automatically close, having a better waterproof and dustproof effect.

[0033] An opening arc plate 121 is provided at one end of the cover 12 away from its connection with the housing 1. The opening arc plate 121 is integrally formed with the cover 12. The distance between the opening arc plate 121 and the housing 1 is greater than the distance between the cover 12 and the housing 1; when the cover 12 is closed, the gap formed between the opening arc plate 121 and the housing 1 is convenient for the user's finger to insert, and the opening and closing operations of the cover 12 can be easily completed.

[0034] Referring to Figure 2 and Figure 3 , the metal sleeve 3 provided on the PCB board 2 is a copper sleeve. The copper sleeve has good electrical conductivity and low cost, and is suitable for ordinary application scenarios. A positioning ring 31 is integrally formed on the outer side wall of the metal sleeve 3. The positioning ring 31 is in contact with the end wall of the PCB board 2 to limit the position of the metal sleeve 3.

[0035] A metal elastic tightening ring 6 is arranged inside the metal sleeve 3. A placement ring groove 32 is opened on the inner wall of the metal sleeve 3. The metal elastic tightening ring 6 is placed in the placement ring groove 32. Both ends of the metal elastic tightening ring 6 abut against the inner side end wall of the placement ring groove 32. The inner diameter of the metal elastic tightening ring 6 decreases from both ends in the axial direction to the middle, and the middle of the metal elastic tightening ring 6 elastically abuts against the plug-in terminal 5.

[0036] The metal elastic clamping ring 6 includes a spring steel ring and a metal elastic piece. The spring steel ring utilizes the elastic characteristics of the material to tightly clamp the plug-in terminal 5, ensuring good electrical contact; the metal elastic piece also ensures the reliability of the elasticity and the stability after long-term use through the optimized selection of the material. When the metal elastic clamping ring 6 is arranged inside the metal sleeve 3, it is fixed by the inner wall of the placing ring groove 32, ensuring that the metal elastic clamping ring 6 is not easily detached during the installation and disassembly of the plug-in terminal 5. The middle part of the spring steel ring is slightly inwardly contracted to form elastic deformation, so that it can apply a certain outward pressure to the inserted plug-in terminal 5, ensuring tight contact between the terminals, and thus achieving good electrical conductivity and structural stability. The metal elastic clamping ring 6 not only improves the connection reliability between the plug-in terminal 5 and the PCB board 2, but also makes the entire socket have a better user experience and safety.

[0037] The mating relationship between the plug-in terminal 5 and the metal sleeve 3 adopts a tight fit design to ensure that the plug-in terminal 5 can be firmly embedded in the metal sleeve 3 during installation and form a stable electrical connection. This tight fit design not only ensures good electrical conductivity, but also improves the reliability and service life of the charging socket.

[0038] Refer to Figure 2 , an abutting protrusion 11 is integrally formed on the inner wall of one end of the housing 1 away from the insertion port. The linear abutting protrusion 11 is suitable for low-speed contact occasions and can achieve a reliable fixed connection with the end of the plug-in terminal 5 after it is inserted into the metal sleeve 3, reducing the problem of poor contact caused by terminal loosening during use. Through the action of the abutting protrusion 11, the plug-in terminal 5 can be in close contact with the protrusion after being inserted into the metal sleeve 3, enhancing the stability and reliability of the overall socket.

[0039] Refer to Figure 2 , a plurality of cover plates 13 are detachably arranged on the outer wall of one end of the housing 1 close to the PCB board 2, and there is a replacement area between the cover plates 13 and the housing 1. The replacement area provided between the cover plates 13 and the housing 1 can accommodate power cords of different lengths. This design not only takes into account the different requirements of users for the length of the power cord, but also simplifies the maintenance and replacement operation steps in practical applications. Specifically, when the power cord needs to be replaced, only the corresponding cover plate 13 needs to be removed, and the power cord can be quickly replaced in the replacement area without disassembling the entire outer shell, improving the maintenance efficiency. At the same time, the housing 1 can be provided with a card slot or a network port at the position of the cover plate 13. The card slot is used to fix other components inside the socket, providing better structural support; the network port reserves space for installing communication modules such as SIM cards, facilitating later upgrades and maintenance.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
