  • the low voltage cabling safety connector is also referred to as HV Interlock (High Voltage Interlock) or pilot contact or pilot line.
  • HV Interlock High Voltage Interlock
  • pilot contact or pilot line In known from practice motor vehicles or drive unit cabling systems this safety connector is designed as a separate module. There is therefore a risk that the plug connection of the high-voltage cabling is disconnected or connected by a person working on the drive unit even when the high-voltage cabling is still under voltage. This is disadvantageous for safety reasons.
  • a further disadvantage of drive unit wiring systems known from practice is that, in particular, the high-voltage cabling is excited to oscillate during operation, as a result of which it can be damaged.
