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.
The adaptor is made of elastomeric material and is provided with an integrally bonded semiconductive layer on the stress relief cone area, the largest diametrical extent of which is provided with an annular flange. The semiconductive layer is feathered at its outer extents in that it diminishes in layer thickness to be contiguous with the insulative portion of the stress relief cone at the other end. The structure of the adaptor is particularly suited for constructing high voltage cable terminations free of voids or air pockets particularly where it is used in the field.
