Plug-in connecting adapter for making an electrical link between a motor vehicle's power network and that of a trailer selects between a trailer and a hook-on carrier

摘要

A motor vehicle's power network (100) has a multi-pole connector plug (101). A trailer's power network (200) also has a multi-pole connector plug (201). Both networks interlink after inserting an adapter (300) with electrical contacts for the vehicle (102) and the trailer (202). These contacts interconnect via current paths (301-304).
