DEFINITION

Classification: 337/199

(under subclass 186) Subject matter wherein the housing, casing or support structure comprises means; (1) whereby a conductive connection is established between the support and ground or other conducting body serving as ground, (2) a dielectric structure whereby any discharge between conducting surfaces within the structure is prevented, or (3) a metallic covering or screen whereby any electrical leakage fields outside the casing are prevented. For example, a corona shield.
