  • Patent number: 4159860
    Abstract: A high voltage cable coupler for releasably connecting together one or more high voltage cables having a concentrically located insulated conductor bounded by a semiconductive and/or metallic shield. The cable housing is provided to be in two moisture-proof halves, one-half for supporting the female connector assembly and the other half for supporting the male connector assembly. Each cable terminus includes a cable termination adaptor which provides a stress relief cone as well as insulative means in combination with an insulator tube assembly within which the conductor connector is secured. This combination also provides for proper positioning and support of the adaptor assembly within the housing as well as providing definitive means for the relationship separation of the termination of the cable shielding and the conductor connector which has an influence on the resultant creepage path.

  • Patent number: 4074926
    Abstract: A universal electrical connector particularly adaptable for terminus applications of high voltage cables. The insulative body portions of the connector employ a combination of engaging primary and secondary tapers. One body portion represents a plug member and the other body portion represents a socket member. Each body portion taper is a frusto-conical contour. The primary set of mating plug and socket tapers constitute nonlocking mating tapers and the secondary set of mating plug and socket surfaces constitute holding tapers. These engaging tapered surfaces together provide an interference fit upon plug and socket engagement. The double taper interference fit of the engaging surfaces provides high electrical integrity upon plug and socket engagement, but minimal disconnecting frictional encounter upon plug and socket disengagement.Each connector body portion has perimetric resilient flange. The engagement and securement of these flanges provides environmental sealing.
