Description

Technical Field

[0001] This utility model relates to the field of AC / DC charging socket technology, specifically an integrated charging socket for high current. Background Technology

[0002] Electric vehicles are gaining increasing attention from automakers due to their wide range of energy sources, quiet operation, and zero emissions, leading to the widespread launch of electric vehicles for home use. Currently, electric vehicle charging sockets commonly use AC / DC charging sockets, which include both AC and DC charging ports. The charging terminals of these sockets are primarily made of copper, and their structures fall into two categories: solid terminals, which are less prone to deformation and have high structural strength, but are more expensive; and hollow terminals, which, while reducing costs, have lower structural strength, are more susceptible to deformation, and have a shorter lifespan. Furthermore, current AC / DC charging sockets transmit power via cables, limiting the amount of current they can handle and thus hindering effective charging speed improvements. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated charging socket with excessive current to solve the deficiencies of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: an integrated charging socket for high current, comprising a panel, a back cover mounted on the panel, and a DC charging module and an AC charging module integrated on the back cover. The AC charging module includes multiple cable entry terminals and return terminals. The cable entry terminals are connected to externally introduced cables. Each cable entry terminal includes a copper tube and an insulating cap. The copper tube is hollow, and the insulating cap is injection molded inside the copper tube to form an integrally coated structure. The DC charging module includes a DC charging housing, aluminum busbars, and DC terminals. The DC terminals are disposed within the DC charging housing, which is connected to the panel. Multiple aluminum busbars are disposed on the DC charging housing, installed longitudinally, and each aluminum busbar is connected to a DC terminal. Both the return terminals and the DC terminals adopt an integrally coated structure.

[0005] Furthermore, one end of the DC terminal extends into the DC charging housing and is fixed with a pin plate. The pin plate has a threaded hole, and one end of the aluminum busbar has a through hole. A screw passes through the through hole and is threaded into the threaded hole of the pin plate.

[0006] Furthermore, an AC circuit board is installed inside the panel. The AC circuit board has mounting holes at the positions of the corresponding circuit terminals. A conductive post is fixed to one end of the circuit terminal near the AC circuit board. Several arc-shaped spring pieces are fixed to the side wall of the conductive post. The arc-shaped spring pieces are evenly distributed around the circumference of the conductive post. The arc-shaped spring pieces are interference-fitted into the mounting holes by their own deformation.

[0007] Furthermore, the rear cover has a through-hole for cable entry, through which the cable is inserted and connected to the cable entry terminal. Multiple elastic teeth are fixed inside the cable entry hole, and the multiple elastic teeth are evenly distributed around the circumference of the cable entry hole. A step is formed on the copper tube, and the elastic teeth engage with the step on the copper tube.

[0008] Furthermore, thermally conductive silicone is fitted onto the copper tube, and the thermally conductive silicone contacts the AC circuit board.

[0009] Furthermore, the AC circuit board is connected to a mounting plate by screws, and a sealing plate is fixed on the mounting plate. The sealing plate has sealing holes for cable entry terminals and return terminals to pass through, and both the cable entry terminals and return terminals are interference-fitted with the sealing holes.

[0010] Furthermore, a T-shaped sealing ring is interference-fitted into the cable inlet hole, and the T-shaped sealing ring is interference-fitted onto the cable.

[0011] Furthermore, a tail cover is installed at the end of the rear cover away from the panel. The tail cover has a through hole for the cable to pass through. A boss is fixed on the side wall of the rear cover. An installation groove is opened on the side wall of the tail cover. The boss is adapted to the installation groove.

[0012] The beneficial effects of this utility model are:

[0013] 1. Charging new energy vehicles via aluminum busbars allows for a larger current flow, thus increasing charging speed.

[0014] 2. The insulating cap is injection molded into the hollow copper tube to form an integrated rubber-coated structure, making the rubber-coated injection molded terminal a solid structure, improving the structural strength of the terminal, extending the service life of the terminal, and at the same time, the plastic injection filling improves the structural strength of the terminal while reducing costs, avoiding the risk of breakage and detachment of the separate insulating cap during assembly.

Detailed Implementation

[0022] Example 1

[0023] like Figures 1 to 6As shown, an integrated charging socket for high current 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 AC charging module includes multiple cable entry terminals and return terminals. The cable entry terminals connect to externally introduced cables and include a copper tube 3 and an insulating cap 4. The copper tube 3 is hollow, and the insulating cap 4 is injection molded inside the copper tube 3 to form an integral encapsulated structure. The DC charging module includes a DC charging housing 5, aluminum busbars 6, and DC terminals 7. The DC terminals 7 are disposed inside the DC charging housing 5 and are connected to the panel 1. Multiple aluminum busbars 6 are disposed on the DC charging housing 5, installed longitudinally, and each of the multiple aluminum busbars 6 is connected to a DC terminal 7, a return terminal, and a DC charging module. Terminals 7 all adopt an integrated rubber-coated structure. The insulating cap 4 is injection molded inside the hollow copper tube 3 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 4 during assembly. In specific implementation, the cable inlet terminal and return terminal are matched with the charging hole of the charging plug to realize charging plug-in, providing two charging methods, namely AC charging and DC charging. AC charging is completed through traditional cable power transmission, while DC charging is transmitted through aluminum busbar 6, which can carry a larger current and improve the charging speed. The aluminum busbar 6 is installed longitudinally to adapt to new energy vehicles with longitudinal plugs.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, one end of the DC terminal 7 extends into the DC charging housing 5 and is fixed with a pin plate 8. The pin plate 8 has a threaded hole, and one end of the aluminum busbar 6 has a through hole. The screw 9 passes through the through hole and is threaded into the threaded hole of the pin plate 8. The pin plate 8 and the aluminum busbar 6 are connected together by the screw 9, so that the DC terminal 7 and the aluminum busbar 6 are electrically connected.

[0025] Example 2

[0026] Based on Example 1, such as Figures 1 to 5 As shown, an AC circuit board 10 is installed inside the panel 1. The AC circuit board 10 has mounting holes 11 at the positions of the corresponding circuit terminals. A conductive post 12 is fixed to one end of the circuit terminal near the AC circuit board 10. Several arc-shaped spring pieces 13 are fixed to the side wall of the conductive post 12. The arc-shaped spring pieces 13 are evenly distributed around the circumference of the conductive post 12. The arc-shaped spring pieces 13 are interference-fitted into the mounting holes 11 by their own deformation. The circuit terminal is installed on the AC circuit board 10 by the deformation of the arc-shaped spring pieces 13. The installation is simple and quick, and it is also easy to disassemble.

[0027] Furthermore, the rear cover 2 has a through-hole 14 for cable entry. The cable passes through the cable entry hole 14 and connects to the cable entry terminal. Multiple elastic teeth 15 are fixed inside the cable entry hole 14. The multiple elastic teeth 15 are evenly distributed around the circumference of the cable entry hole 14. A step is formed on the copper tube 3. The elastic teeth 15 are engaged with the step of the copper tube 3. When the cable entry terminal is inserted into the cable entry hole 14, the elasticity of the elastic teeth 15 causes the elastic teeth 15 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.

[0028] Example 3

[0029] Based on Embodiment 2, thermally conductive silicone 16 is sleeved on the copper pipe 3. The thermally conductive silicone 16 contacts the AC circuit board 10 and dissipates heat between the cable inlet terminal and the AC circuit board 10 through the thermally conductive silicone 16.

[0030] Example 4

[0031] Based on Example 3, such as Figures 1 to 6 As shown, the AC circuit board 10 is connected to the mounting plate 17 by screws. A sealing plate 18 is fixed on the mounting plate 17. The sealing plate 18 has a sealing hole 19 for the cable inlet terminal and the return terminal to pass through. The cable inlet terminal and the return terminal are both interference fit with the sealing hole 19, forming a sealing surface below the AC circuit board 5 to prevent moisture, dust and other substances from entering the back cover 2 through the panel 1. A T-shaped sealing ring 20 is interference fitted in the cable inlet hole 14. The T-shaped sealing ring 20 is interference fitted on the cable, forming a sealing surface above the AC circuit board 10, thereby completely sealing the working environment of the AC circuit board 10.

[0032] Example 5

[0033] Based on Example 4, such as Figure 1 As shown, a tail cover 21 is installed at the end of the rear cover 2 away from the panel 1. The tail cover 21 has a through hole for the cable to pass through. A boss 22 is fixed on the side wall of the rear cover 2. An installation groove 23 is opened on the side wall of the tail cover 21. The boss 22 fits into the installation groove 23. The tail cover 21 is elastic. The elasticity of the tail cover 21 allows the boss 22 to fit into the installation groove 23. After removing the tail cover 21, the T-shaped sealing ring 20 can be installed into the cable inlet hole 14.
