Technical Field

[0001] This utility model belongs to the field of automotive charging dock technology, and particularly relates to a charging dock assembly and a charging dock. Background Technology

[0002] Automobiles are one of the most common means of transportation in modern life. They generally consist of four basic parts: engine, chassis, body, and electrical equipment, offering the advantage of convenient travel. In recent years, with continuous technological advancements, new energy vehicles have become increasingly popular. Common new energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. They require an external power source to replenish their electricity. During charging, a charging socket fixed to the vehicle body connects with a charging plug containing a power cord to form a charging circuit, completing the task of charging the electric vehicle.

[0003] Currently, the AC charging terminals for new energy vehicles generally adopt a structure in which the charging terminals and connecting cables are crimped or welded together, and then the cables are led out to the outside of the charging base one by one. The number of terminals and cables is too large, which can easily lead to misinstallation or omission, resulting in increased product production costs or functional failure. Summary of the Invention
