The goal is clear, to absolutely ensure that the connection locks securely and prevents the connection from loosening in adverse driving conditions.
As traditional gasoline vehicles give way to electric vehicles, in-vehicle equipment, which is usually powered by the engine, has instead begun to rely on the vehicle’s high-voltage electrical architecture for power. Some of the original 12V equipment (such as electric heating, air conditioning compressors, on-board chargers, or some DC/DC converters that are usually less than 100A) can also be converted to higher voltages to improve operating efficiency. High-voltage connectors for auxiliary equipment need to be packaged in a compact form, so as to provide the required power while saving space and volume as much as possible. Connector solutions for auxiliary equipment are diverse, including single-core (independent) shielded, multi-core shielded, bundled shielded, and unshielded systems.
