Compact circuit board for an automotive HVAC system

摘要

An automotive heat, ventilation and air conditioning (HVAC) system (20) includes an electrical control module (30) for controlling the motor (26) of the system (20). The module (30) includes a connector base (32) supporting a circuit board (36) having spaced side edges extending into the housing (22) . The circuit board (36) has a first leg (40) extending from the base (32) and through a curved section (42) and into a second leg (44) to a distal end spaced from the base (32) with an electrical circuit (38) extending over the exterior of the first leg (40) and over the curved section (42) and over the second leg (44). The circuit board (36) includes an offset section (46) between the base (32) and the first leg (40) for centralizing the legs (40,44) on the base (32) .
