Abstract: A top shield arrangement for elongated filter traps, comprising an elongated sleeve member adapted to receive through one and thereof at least one filter trap such that the filter trap lies completely inside the sleeve member. The sleeve member is formed at the other end thereof for preventing withdrawal of the filter trap from the other end. A wafer seal is inserted into the sleeve member at the one end of the sleeve member for preventing unauthorized removal of the filter trap from the sleeve member through the one end thereof. The top shield arrangement of the invention protects filter traps against tampering by unauthorized persons.

Abstract: A ground connector for securing a grounding wire to a conductive shield of a coaxial cable. The connector comprises a strip of flexible sheet metal which is configured to be bent to form a grounding wire attachment loop and a coaxial cable loop. The strip of sheet metal defines clamp portions each having a fastener securing aperture. A fastener clampingly engages the clamp portions through the apertures to clampingly engage the grounding wire attachment loop and the coaxial cable loop about respectively to a grounding wire and a conductive shield of a coaxial cable. At least the coaxial cable loop has an inner serrated surface portion for frictional retention with an outer surface of the conductive shield when clamped substantially thereabout by the tightening of the fastener and prevents the shield from being punctured or damaged thereby.
