Technical Field

[0001] This utility model relates to an NACS / J1772 adapter. Background Technology

[0002] Utility model patent application CN117832901A discloses an AC charging converter for new energy vehicles, including a main housing and a nozzle mounted on the lower end of the main housing. The upper end of the main housing has a first connecting end, and the lower end of the nozzle has a second connecting end. The main housing is internally provided with a positioning wheel and a positioning frame located below the positioning wheel. The positioning frame is provided with an installation end. The first connecting ends of a first control adapter and a second control adapter are respectively mounted on the positioning wheel. A control module is provided below the positioning wheel. The control module has a first input end, a second input end, a first output end, and a second output end. The lower ends of the first connecting ends of the first control adapter and the second control adapter are respectively connected to the first input end and the second input end. The second connecting ends of the first control adapter and the second control adapter are respectively mounted on the installation end and respectively connected to the first output end and the second output end. This patent application represents our company's first-generation product. In this product, a second handle is rotatably mounted on the outside of the main housing via a second pin. The upper end of the second handle has a second hook, and the lower end of the second handle is supported on the housing by a second spring. However, users have discovered a defect in this structure. Although the second hook uses the second spring to secure the connection end via a lever structure, this connection easily detaches when a slight separation force is applied. Since the voltage and current of new energy vehicle charging are relatively high, this defect needs to be addressed for charging safety. Summary of the Invention

[0022] Appendix Figure 1 A perspective view of the NACS / J1772 adapter according to this utility model is attached. Figure 2 This is a perspective exploded view of the NACS / J1772 adapter according to this utility model. The NACS / J1772 adapter in this embodiment includes a housing base 1, a housing 2 mounted on the housing base 1, a first locking unit, and a second locking unit. The housing base 1 and housing 2 are fixed together by self-locking screws 18. The overall material is made of flame-retardant and high-pressure resistant engineering plastic to achieve a safety level. The housing base 1 has a first connection end for connecting to a charging gun, and the housing 2 has a second connection end for connecting to a charging socket. A gun head liner 16 is installed inside the second connection end of the housing 2, and a gun head sealing ring 17 is provided between the housing 2 and the gun head liner 16.

[0023] The first locking unit is configured to lock together with the charging gun when the charging gun is connected to the first connection end. The first locking unit includes a positioning seat 3 mounted on the housing 1, a first handle 4 mounted on the positioning seat 3, and a cover 5 mounted on the first handle 4. The positioning seat 3 is mounted on the housing 1 by a plurality of locking pins 19. The middle part of the first handle 4 is rotatably mounted on the positioning seat 3 by a first pin 6, and the two ends of the first pin 6 are connected to the cover 5.

[0024] The second locking unit is configured to lock together with the charging dock when the charging dock is connected to the second connection end. The second locking unit includes a second handle 9 mounted on the housing 1. The middle part of the second handle 9 is rotatably mounted on the housing 1 via a second pin 10. One end of the second handle 9 forms a second pressing part 91, and the other end of the second handle 9 has a hook 92. A torsion spring 11 is sleeved on the second pin 10 to lock the hook 92 together with the charging dock.

[0025] A pair of high-voltage adapter terminals 12, a pair of control adapter terminals 13, and a grounding adapter terminal 14 are provided between the housing 1 and the housing 2. The high-voltage adapter terminals 12, 13, and 14 each have a first adapter end and a second adapter end. The first adapter end extends into the first connection end of the housing 1, and the second connection end extends into the second connection end of the housing 2. The second adapter ends of the high-voltage adapter terminals 12 and 14 are formed into a clamp-like structure by milling grooves from silver-plated copper pillars. The terminal interface uses milling grooves to create a clamp-like contact to ensure good contact and prevent overheating caused by incomplete contact. The diameters of the high-voltage adapter terminals 12 and 14 are larger than the diameter of the control adapter terminal 13. Rubber rings 20 are fitted around the middle portions of the high-voltage adapter terminals 12 and 14. The conversion conductors are made of copper cylinders to increase the operating current and reduce the disadvantage of overheating caused by the wires.

[0026] A rubber-coated circuit board 15 is disposed between the outer casing 1 and the outer casing 2, with the outer casing being rubber-coated to achieve a sealing effect. High-voltage adapter terminal 12 and grounding adapter terminal 14 pass through the cutouts in the rubber-coated circuit board 15. A control adapter terminal 13 is connected to the rubber-coated circuit board 15. The rubber-coated circuit board 15 has a control unit configured to output a control signal based on the input signal from the control adapter terminal 13. A micro switch 16 is disposed on the rubber-coated circuit board 15. The hook 92 of the second handle 9 is elastically pressed against the micro switch 16. When the second pressing part 91 is pressed, the control unit outputs a shutdown control signal.

[0027] Appendix Figure 3 A perspective view of the first locking unit of the NACS / J1772 adapter according to this utility model; attached. Figure 4 This is a schematic diagram illustrating the working principle of the first locking unit of the NACS / J1772 adapter according to this utility model. One end of the first handle 4 forms a first pressing part 41, which is elastically supported on the positioning seat 3 by a first spring 7. The other end of the first handle 4 is equipped with a locking tongue 42, which is rotatably connected to the end of the first handle 4. The positioning seat 3 has a corresponding opening 31. The upper part of the locking tongue 42 is elastically supported between itself and the cover 5 by a second spring 8, allowing the locking tongue 42 to pass through the opening 31 and extend into the first connecting end to lock with the charging gun. This double locking structure of the first spring 7 and the second spring 8 effectively ensures a firm locking force under separation force during use. Only when the first pressing part 41 presses down and tightens the first spring 7, the second spring 8 is also compressed under leverage, allowing the locking tongue 42 to retract, thus ensuring safety during charging. In addition, a guide plate 32 extending vertically is provided at the opening 31. Since the locking tongue 42 is rotatably connected to the first handle 4, the locking tongue 42 can always remain vertical as it extends into or out of the opening 31 along the guide plate 32, thus ensuring the stability of the lock.
