摘要:
A heater assembly (10) includes a heating member (12), a mounting member (14) that mounts the heating member (12) to a wall (16) of an external component, and an insulator (22) disposed between the heating member (12) and the wall (16). The insulator (22) electrically insulates the heating member (12) from the wall (16) and blocks a ground path from the heating member (12) to the wall (16) of the external component.
