Detailed Implementation

[0025] Example 1

[0026] like Figures 1 to 7 As shown, an aluminum busbar integrated charging socket includes a panel 1, a back cover 2 mounted on the panel 1, and a DC charging module and an AC charging module integrated on the back cover 2. The DC charging module includes a DC charging housing 3, aluminum busbars 4, and DC terminals 5. The DC terminals 5 are disposed inside the DC charging housing 3, which is connected to the panel 1. Multiple aluminum busbars 4 are disposed on the DC charging housing 3 and are installed horizontally. Each aluminum busbar 4 is connected to a DC terminal 5 to enable charging plug-in. It provides two charging methods: AC charging and DC charging. AC charging is completed through traditional cable power transmission, while DC charging is transmitted through the aluminum busbars 4, which can carry a larger current and improve the charging speed. The horizontal installation of the aluminum busbars 4 is suitable for new energy vehicles with horizontal sockets.

[0027] Example 2

[0028] Based on Example 1, such as Figures 1 to 4As shown, the top of the DC terminal 5 extends into the DC charging housing 3 and has a threaded hole. The aluminum busbar 4 has a through hole. The end of the aluminum busbar 4 with the through hole is slidably inserted into the DC charging housing 3. The tail of the screw 6 passes through the through hole and is threaded into the threaded hole. Due to the horizontal installation of the aluminum busbar 4, the aluminum busbar 4 and the DC terminal 5 are arranged vertically. In order to realize the electrical connection between the DC terminal 5 and the aluminum busbar 4, a threaded hole is opened on the top of the DC terminal 5. The aluminum busbar 4 and the DC terminal 5 are connected together by the screw 6 to improve the stability of the connection.

[0029] Example 3

[0030] Based on Example 2, such as Figures 1 to 4 As shown, a boss is formed on the top of the DC charging housing 3, and an operation hole 7 is provided on the boss. The operation hole 7 is coaxially arranged with the threaded hole. A blind plug 8 is provided on the top of the operation hole 7. A cover plate 10 is mounted on the boss, and the cover plate 10 presses the blind plug 8 against the boss. An elastic buckle 9 is fixed on the side wall of the boss, and an installation groove 11 is provided on the side wall of the cover plate 10. The elastic buckle 9 is adapted to the installation groove 11. By providing the operation hole 7, it is convenient to connect the aluminum busbar 4 to the DC terminal 5 through the operation hole 7. To connect or disconnect, press the elastic buckle 9 to deform it, causing the elastic buckle 9 to disengage from the mounting groove 11 of the cover plate 10, and then remove the cover plate 10. Then remove the blind plug plate 8 to expose the operating hole 7, and then install or remove the aluminum busbar 4. After the aluminum busbar 4 is connected to the aluminum DC terminal 5, cover the boss with the blind plug plate 8 to seal the operating hole 7. Then install the cover plate 10 to press the blind plug plate 8 tightly onto the boss, improving the sealing effect of the operating hole 7 and providing better dustproof and waterproof effects.

[0031] Example 4

[0032] Based on Example 3, such as Figure 1 , Figure 2 , Figures 5 to 7 As shown, the AC charging module includes multiple cable entry terminals and multiple circuit terminals disposed within the rear cover 2. The cable entry terminals connect to externally introduced cables. Each cable entry terminal includes a copper tube 12 and an insulating cap 13. The copper tube 12 is hollow, and the insulating cap 13 is injection molded inside the copper tube 12 to form an integrated rubber-coated structure. Both the circuit terminals and the DC terminals 5 adopt an integrated rubber-coated structure. The insulating cap 13 is injection molded inside the hollow copper tube 12 to form an integrated rubber-coated structure, making the injection-molded terminal a solid structure, improving the structural strength of the terminal, and extending the service life of the terminal. At the same time, the plastic injection filling improves the structural strength of the terminal while reducing costs, and avoids the risk of breakage and detachment of the separate insulating cap 13 during assembly.

[0033] Example 5

[0034] Based on Example 4, such as Figures 5 to 7As shown, an AC circuit board 14 is installed inside the panel 1. The AC circuit board 14 has mounting holes 15 at the positions of the corresponding circuit terminals. A conductive post 16 is fixed to one end of the circuit terminal near the AC circuit board 14. Several arc-shaped spring pieces 17 are fixed to the side wall of the conductive post 16. The arc-shaped spring pieces 17 are evenly distributed around the circumference of the conductive post 16. The arc-shaped spring pieces 17 are interference-fitted into the mounting holes 15 by their own deformation. The circuit terminal is installed on the AC circuit board 14 by the deformation of the arc-shaped spring pieces 17. The installation is simple and quick, and it is also easy to disassemble.

[0035] Furthermore, the rear cover 2 has a through-hole 19 for cable entry. The cable passes through the cable entry hole 19 and connects to the cable entry terminal. Multiple elastic teeth 20 are fixed inside the cable entry hole 19. The multiple elastic teeth 20 are evenly distributed around the circumference of the cable entry hole 19. A step is formed on the copper tube 12. The elastic teeth 20 are engaged with the step of the copper tube 12. When the cable entry terminal is inserted into the cable entry hole 19, the elasticity of the elastic teeth 20 causes the elastic teeth 20 to pass through the step and abut against the bottom of the step, thereby quickly connecting the cable entry terminal to the rear cover 2.

[0036] Example 6

[0037] Based on Example 5, such as Figure 1 , Figure 2 , Figures 5 to 7 As shown, the AC circuit board 14 is connected to a mounting plate 22 by screws. A sealing plate 23 is fixed on the mounting plate 22. The sealing plate 23 has a sealing hole 24 for the cable inlet terminal and the return terminal to pass through. The cable inlet terminal and the return terminal are both interference-fitted with the sealing hole 24, forming a sealing surface below the AC circuit board 14 to prevent moisture, dust, etc. from entering the back cover 2 through the panel 1. A T-shaped sealing ring 25 is interference-fitted in the cable inlet hole 19. The T-shaped sealing ring 25 is interference-fitted on the cable, forming a sealing surface above the AC circuit board 14, thereby completely sealing the working environment of the AC circuit board 14.

[0038] Furthermore, a tail cover 26 is installed at the end of the rear cover 2 away from the panel 1. The tail cover 26 has a through hole for the cable to pass through. A boss 27 is fixed on the side wall of the rear cover 2. An installation groove 28 is opened on the side wall of the tail cover 26. The boss 27 fits into the installation groove 28. The tail cover 26 is elastic. The elasticity of the tail cover 26 allows the boss 27 to fit into the installation groove 18. After removing the tail cover 26, the T-shaped sealing ring 25 can be installed into the cable inlet hole 19.

[0039] Example 7

[0040] Based on Example 6, such as Figure 5As shown, thermally conductive silicone 21 is fitted on the copper pipe 12. The thermally conductive silicone 21 contacts the AC circuit board 14 and dissipates heat between the cable inlet terminal and the AC circuit board 14 through the thermally conductive silicone 21.
