Abstract
This application belongs to the field of automotive charging technology and discloses an automotive DC fast-swap charging socket, including an outer insulating shell, an inner insulator detachably disposed inside the outer insulating shell, and a circuit board disposed at the rear end of the inner insulator within the outer insulating shell. The circuit board has 6 pin holes, 1 PE hole, 2 power holes, 1 low-voltage connector, and 1 surface mount resistor. Pin contacts are disposed in the pin holes, PE contacts are disposed in the PE holes, and signals from the pin contacts and surface mount resistor are transmitted to the low-voltage connector through the circuit board body. Power contacts are disposed in the power holes. Nine hollow terminal blocks are correspondingly disposed on the inner insulator. A pressure plate tail cover is disposed at the rear end of the outer insulating shell. The detachable separation of the inner and outer insulating shell allows for the removal and replacement of the inner insulator for repair or replacement when parts age or malfunction, without disassembling the entire socket. This improves repair efficiency, reduces repair costs, and enables fast-swap functionality.
