The intermediate cover divides the housing into a partial conduit which is not accessible to the outside adapted to receive the supply cables, and a portion which is covered by the detachable cover and adapted to receive the ground plates and motor bars. Grooves formed in the housing securely receive the ground plates in the portion of housing covered by the detachable cover.

Abstract: A strain relief structure is provided for direct cable to circuit board connections. The strain relief structure is securely mountable to the circuit board and comprises a body which includes at least one cable receiving aperture extending therethrough. The cable receiving aperture is characterized by a deflectable strain relief engagement for engaging the insulation on the cable and providing necessary strain relief. The aperture is constructed to alternatively permit first and second depths of insertion, each of which permits engagement of the strain relief structure with the cable. The first depth of insertion substantially encloses the exposed conductors of the cable to prevent damage during shipment and storage. The second depth of insertion enables electrical connection between the cable conductors and conductive areas on the circuit board.

Abstract: The electric fence insulator is of linear polyethylene. The insulator includes a vertical panel having a first L-shaped clip thereon providing a downwardly directed prong. A pair of laterally spaced L-shaped clips provide a pair of upwardly directed prongs each having a rib extending therealong. The ribs render these last-mentioned prongs relatively rigid with respect to the downwardly extending prong. The downwardly extending prong has its lower end at an elevation beneath the elevation of the upper ends of the upwardly extending prongs to assure retention of an electric fence conductor by reason of the overlapping prongs.

Abstract: An improved plate for mounting a plurality of receptacles on an electronics device, particularly a data communications peripheral, is disclosed. The plate is designed to be secured to an electronic subassembly which may be dropped into a portion of an enclosure and the plate placed proximate to a large opening in the enclosure. In order to compensate for mechanical tolerances on the fit of the plate within the enclosure, since it is attached to the subassembly, free edges of the plate which may act as an elongated antenna for emitting radio frequency interference are broken up into fingers of predetermined length. This attenuates the radiation from such edge. Additionally, the fingers are bent down to contact an electrically grounded portion of the enclosure to provide further RFI suppression.
