Secondary transformer device for attachment to motor car for inductively coupling with primary transformer device, has spacer designed so that damage to spacer by alteration of physical quantity measured by measuring unit is prevented

摘要

The secondary transformer device (10) has a secondary coil (12) which is partially arranged in a housing (14). The housing is provided with a spacer (16) which is coupled with a measuring unit. The measuring unit is adapted to measure the physical quantity. The spacer is designed such that the damage to the spacer by the alteration of the physical quantity measured by the measuring unit is prevented. The spacer is electrically conductive and is adapted to guide an electric current. An independent claim is included for motor car.
