YGEV2-4Pin Series Electrical Connectors

  • The product can achieve 360-degree full shielding;

  • The product can realize secondary interlocking and unlocking;

  • The product has a delayed high voltage interlocking function;

  • The key positions at both ends adopt 4 different combinations to realize the function of preventing wrong insertion;

  • The plug and receptacle utilize a direct plug-in locking mechanism for connection.

  • The plug and receptacle adopt terminal crimping.

Suitable for electrical connections of electric vehicle components such as DC/DC converters, PTC heaters, compressors, and high-voltage boxes.
