Description

Technical Field

[0001] The present invention relates to the field of charging sockets, and specifically to an over-current charging socket with split-slot terminals. Background Art

[0002] Due to the characteristics of wide energy sources, quiet driving, and no pollution emissions, electric vehicles have been increasingly valued by various automobile manufacturers, and they have successively launched household electric vehicles. Currently, the charging sockets of electric vehicles often adopt AC-DC charging sockets, which include AC charging sockets and DC charging sockets. At present, the terminals of AC-DC charging sockets are plug-in terminals, which are connected by the insertion of male terminals and female terminals. Their connection is not stable enough, and it is easy to cause loosening or separation of the cable and the socket joint due to reasons such as vibration. Secondly, at present, all AC-DC charging sockets conduct power transmission through cables and cannot pass over-current, so their charging speed cannot be effectively improved.

After the slotted terminal 3 is inserted into the charging plug, the protrusion of the charging plug is fitted into the insertion slot 4. The protrusion on the charging plug is also made of copper material. By using the elasticity of the copper tube 3 and the elasticity of the protrusion, the protrusion is interference-fitted into the insertion slot 4, improving the connection strength between the charging plug and the slotted terminal, making the connection between the cable and the socket more stable and improving the seismic performance. The DC module includes a DC charging socket mounting plate 5 and an aluminum row male plug 6. An installation space is formed between the DC charging socket mounting plate 5 and the panel 1. The aluminum row male plug 6 is arranged in the installation space. An aluminum row assembly is arranged on the DC charging socket mounting plate 5. The aluminum row assembly includes an aluminum row mounting housing 7 and an aluminum row 8. The aluminum row mounting housing 7 is fixed on the DC charging socket mounting plate 5. A plurality of aluminum rows 8 are arranged at one end of the aluminum row mounting housing 7. The aluminum rows 8 are horizontally installed.

The elastic buckle 13 is adapted to be arranged in the installation groove 14. By forming the operation hole 10, it is convenient to connect or disassemble the aluminum busbar 8 and the aluminum busbar male plug 6 through the operation hole 10. Specifically, press the elastic buckle 13 to deform, so that the elastic buckle 13 disengages from the installation groove 14 of the cover plate 12, and then the cover plate 12 can be removed. Then, the blind plug plate 11 is taken off to expose the operation hole 10, and the aluminum busbar 8 can be installed or disassembled. After the connection between the aluminum busbar 8 and the aluminum busbar male plug 6 is completed, the blind plug plate 11 is covered on the boss to block the operation hole 10, and then the cover plate 12 is installed to press the blind plug plate 11 on the boss, improving the sealing effect on the operation hole 10 and having a good dust-proof and waterproof effect.
