HVIL, or high voltage interlock loop connector, is a safety feature of hybrid and all-electric vehicles that protects people during the assembly, repair, maintenance and operation of a vehicle. The HVIL system is in place to protect those who may come into contact with high-voltage components at any stage of the electric vehicle lifecycle. HVIL acts as a circuit breaker that sends an alert or trouble code to the driver if a high-voltage connection becomes loose, disconnected or damaged during the vehicle’s operation. It also helps protect a vehicle’s driver and passengers in the event of an accident.
The exact composition of high voltage interlock loop connector plugs may vary depending on the model and manufacturer, but in general, they contain: Housing, Contacts, Pins, Locking Mechanism, Sealing Ring etc.
HVIL connector consists of a plug wrench with a card slot, a secondary lock with a guide slot and a high-voltage interlock microswitch to form an interlock mechanism. High-voltage interlock connectors include solutions for high-voltage, high-current, and signal connections for hybrid and electric vehicle high-voltage power harnesses and signal connections. It is available in a wide range of product options, 1 core to 3 cores, rated from 23A to 250A, touch resistant, single or multi-core shielded cables are available.
