  • Patent number: 5399095
    Abstract: A device for resolving axial and angular misalignments between electrical conductors of adjacent sections of a pre-bussed rigid conduit electrical feeder system. The variable phase positioning device includes a flexible housing with an end piece attached to each end. A number of flexible electrical conductors are enclosed within the housing. Each conductor is enclosed in an electrically insulating sheath. A substantially rigid terminal is fixedly attached to each end of each conductor. At each end of the housing the terminals are loosely captivated within a terminal support such that each terminal can rotate freely. The terminal supports are made from an electrically insulating material. A retaining sleeve is loosely received over each terminal support and attached to the end piece in a manner that permits the terminal supports to rotate freely within the retaining sleeve.

  • Patent number: 5312265
    Abstract: This invention provides a single type of electrical connector suitable for use with cables containing from one up to the maximum number of electrical conductors that can be accommodated by passages within the connector without impairing the ability of the connector to exclude moisture and other contaminants from the area occupied by junctions between mating pairs of conductors. This is achieved by the combination of a preformed perforated gasket and a layer of penetrable, non-self-healing, non-flowing elastomer that seals all of the passages in the connector not occupied by conductors.
