  • Patent number: 5474460
    Abstract: A power interconnect system for electronic assemblies, for providing electrical connections between a power supply and a remote electrical conductor element, such as a power bus bar. An electrically insulating block is connected to a bus bar, and holds captive a power coupling connector element for engaging and connecting the bus bar to a power supply. The power coupling connector element includes a conductive end and an insulative end to prevent the supply from shorting out or shocking a maintenance person in contact with the insulative end even when the system is powered up. The conductive end has a larger diameter than the insulative end and the entire power coupling connector element is held captive within the block of insulating material when mounted to a power bus bar, to prevent the power coupling connector element from becoming loose within an electronic assembly.

  • Patent number: 5348485
    Abstract: A vertical stringer or rail system is provided for use with an electronic price display system in a store, warehouse or other application. A vertical rail is made of an insulating material and is of substantially constant cross section along its extent, with ridges along each edge. A channel in the front face of the rail carries a plurality of exposed conductors, and the channel and edges are keyed. Snap-on connectors fit to the rail, and due to the keying it is impossible to snap the connector on backwards. The snap-on connectors each have a flat cable running to a shelf rail at the front of a shelf, and electronic price display labels lie within the shelf rail. U-shaped snap-on cable clamps provide clamping of the flat cable to the vertical rail nearby to the snap-on connectors, and the cable clamps are captive to the flat cable so they are not easily misplaced. Because the snap-on connectors and clamps may be snapped on at a multitude of locations they can easily accommodate shelves at varying heights.

  • Patent number: 5336097
    Abstract: An electrical power distribution system is provided with an elongate track and a plurality of power tap assemblies that are engageable with the track. The power tap assemblies may be moved to any desired location along the track. Power may be fed into the track through one of the assemblies and taken out of the track through another of the assemblies. Receptacles may be mounted to one or more of the power tap assemblies. A latch system can hold the power tap assemblies in (1) a fully inserted, electrically engaging orientation and (2) an electrically disconnected orientation wherein the components are still supported on the track. The components employ spring terminals which establish electrical contact through a surface-to-surface butt engagement with a conducting member. Mechanical key systems are provided for preventing improper mounting of the components on the track and for preventing the connection of more than one power in-feed to the track.
