Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to an improved high-voltage connector. Background Art

[0002] High-voltage connectors, also known as high-voltage connectors, generally refer to connectors with an operating voltage of 60V or above and are primarily responsible for transmitting high currents. Currently, high-voltage connectors have been used in new energy vehicles (such as electric vehicles). In the high-voltage, high-current circuits of new energy vehicles, high-voltage connectors and wires work together to transmit battery pack energy through various electrical circuits to high-voltage components in the vehicle system, such as the battery pack, motor controller, DC-DC converter, and charger.

[0003] Existing high-voltage connectors mainly include a socket and a plug. The socket is provided with socket terminals, and the plug is provided with plug terminals that are electrically connected to the socket terminals. A pair of socket terminals and plug terminals that plug into each other can realize a corresponding function of the high-voltage connector.

[0004] However, existing high-voltage connectors have shortcomings: a pair of socket terminals and plug terminals on the high-voltage connector that plug into each other can only realize a single function of the high-voltage connector. Since the requirements for the type and function of high-voltage connectors vary, different high-voltage connectors with the same function cannot be shared with each other. Once a high-voltage connector is required to have multiple functions, a single high-voltage connector cannot adapt to such functional requirements. Therefore, multiple high-voltage connectors are required to complete the multiple functional requirements, resulting in poor interchangeability between high-voltage connectors and many interoperability issues between high-voltage connector products.
