Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging guns, in particular to a modular electric vehicle charging gun head assembly. Background Technique

[0002] Charging technology is constantly evolving with the development of the electric vehicle industry. The new energy electric vehicle charging device is connected through a connector (charging gun, charging socket) and a charging cable. The new energy electric vehicle charging gun is an important component for connecting the new energy electric vehicle and the power supply equipment. The main components of the AC charging gun include a charging gun housing, plug terminals (pins), a plug insulator, a micro switch, a mechanical lock, etc.

[0003] In most of the current market charging gun designs, the mechanical lock, the insulating head, and the micro switch are all independently installed in the gun housing. The cumulative assembly tolerance is large, the assembly is complex, the structural accuracy requirements are high, and the mechanical lock is prone to failure. At the same time, once the shape of the charging gun is changed, parts such as the insulating head need to be redesigned and tooled, and compatible design cannot be achieved. Summary of the Invention

[0004] By providing a modular electric vehicle charging gun head assembly in the embodiments of the present application, by designing a support, a terminal bracket, and an insulating head on the same modular component, the cumulative assembly tolerance is small, the assembly is simple, and it can be directly used modularly, reducing the cost.

[0005] To achieve the above object, the utility model provides the following technical solution: A modular electric vehicle charging gun head assembly, the gun head assembly includes a support that cooperates with the button of the vehicle charging gun head, a terminal bracket for accommodating terminals, and an insulating head. The front end of the insulating head is provided with an integrated centralized mounting seat. The centralized mounting seat is respectively provided with a support connection part, a terminal bracket mounting cavity, and a support fixing part. The terminal bracket is embedded inside the terminal bracket mounting cavity. The tail end of the support is sleeved on the support fixing part and fixedly connected to the support fixing part. The upper part of the tail end of the support is sleeved and positioned with the support connection part for installation.

[0006] Compared with the prior art, the advantages of the utility model are as follows:

[0007] By designing an integrated centralized mounting seat, integrating the support connection part, the terminal bracket mounting cavity, and the support fixing part, the integrated centralized installation of each component is realized. This design not only makes the cumulative assembly tolerance small and the assembly simple, but also optimizes the overall structure, making the charging gun head more compact and lightweight, and can be directly used modularly, reducing the cost;

[0008] The design of the centralized mounting seat provides stronger stability and rigidity for the overall structure, ensuring the stable connection of the gun head assembly during the charging process;

[0009] The tail end of the support is directly sleeved on the support fixing part and fixedly connected thereto. At the same time, it is sleeved and positioned with the support connecting part above. This design greatly simplifies the installation steps, reduces the errors during the installation process, and ensures the precise docking of the charging gun head assembly with the vehicle charging interface.

[0010] As an improvement, a limiting piece protrudes forward at the upper end of the terminal support. A positioning boss is arranged at the upper end of the limiting piece. A positioning hole adapted to the shape of the positioning boss is arranged at the lower end of the support connecting part corresponding to the positioning boss. The front end of the positioning boss abuts against the side wall of the positioning hole, and the upper end of the limiting piece abuts against the lower end of the support connecting part. The tight abutment of the front end of the positioning boss against the side wall of the positioning hole ensures the precise positioning between the terminal support and the support connecting part. This design reduces the assembly difficulty and errors caused by position deviation, improves the stability and reliability of the overall structure. At the same time, the abutment of the upper end of the limiting piece against the lower end of the support connecting part further enhances the connection firmness and prevents loosening or offset.

[0011] As an improvement, the terminal support is embedded in the terminal support installation cavity and joined by the first connection structure. By being embedded and joined in the terminal support installation cavity, the terminal support ensures the firmness and reliability of the connection. The design of embedding and joining usually requires high dimensional accuracy and fitting accuracy to ensure that the terminal support can be accurately installed in the predetermined position. This precise positioning helps to reduce the performance problems caused by installation errors and improves the accuracy and reliability of the overall structure.

[0012] As an improvement, the first connection structure includes first card slots arranged on both sides of the lower end of the terminal support, and first blocks arranged on both side walls of the support fixing part corresponding to the first card slots. The first card slots are engaged with the first blocks. The terminal support and the support fixing part are connected by the engagement of the first card slots and the first blocks, which facilitates the installation and disassembly of the terminal support and the insulating head.

[0013] As an improvement, the tail end of the support is sleeved on the support fixing part and fixedly connected to the support fixing part through the second connection structure. Through the fixed connection of the second connection structure, the connection between the tail end of the support and the support fixing part is tighter, and it is not easy to loosen or displace, thereby enhancing the stability of the overall structure.

[0014] As an improvement, the second connection structure includes second card slots arranged on both sides of the tail end of the support, and second blocks arranged on both side walls of the support fixing part corresponding to the second card slots. The second card slots are engaged with the second blocks. Through the engagement design of the second card slots and the second blocks, the quick connection and disassembly between the support and the support fixing part can be realized. This design does not require additional fasteners or complex operation steps, greatly improving the work efficiency and convenience.

[0015] As an improvement, a fitting groove for the fitting and positioning of the fixing part of the support is provided at the tail end of the support. A plurality of positioning blocks are provided on the inner wall of the fitting groove, and a positioning groove for cooperating with the positioning blocks is provided inside the fixing part of the support. Through the precise cooperation of the positioning blocks and the positioning groove, it can be ensured that the fixing part of the support is firmly fixed in the fitting groove, effectively preventing loosening or deviation caused by external forces or long-term use, thereby greatly enhancing the stability and firmness of the overall structure, and at the same time enabling the support to be positioned and installed on the insulating head.

[0016] As an improvement, a first socket is provided above the tail end of the support, and a second socket is provided on the support connection part. The first socket and the second socket are fitted and positioned to achieve the support connection between the support and the insulating head. Through the fitting and positioning of the first socket and the second socket, the connection between the support and the insulating head becomes extremely stable. This design not only enhances the reliability of the connection, but also improves the anti-vibration and anti-impact capabilities of the entire structure, ensuring the stable operation of the electric vehicle charging gun. At the same time, the precise fitting between the first socket and the second socket ensures the precise positioning and alignment between the support and the insulating head.
