  • Patent number: 7972155
    Abstract: A hotstick operable electrical connector for use in a power distribution system that includes a housing, a well and first and second frustoconical members extending from a surface of the housing. Each frustoconical member has a distal end and an axial bore that extends from the distal end into the housing. The well includes a wall, a base with an aperture and a tapered cavity that extends into the housing from the surface opposite the frustoconical members. The well is adapted to receive a male end of an insert device, such as a feed-thru insert or bushing insert. The aperture provides communication between the cavity and the axial bore of one of the frustoconical members. An electrical contact assembly extends through the aperture between the cavity and the axial bore. The integrally formed well provides a means for direct connection with an insert device without the use of an adapter.

  • Publication number: 20080045058
    Abstract: A high voltage loadbreak bushing insert includes an insulative housing having a first end section, a second end section opposite the first end section, a mid-section disposed between the first and second end sections and a transition shoulder portion disposed between the second end section and the mid-section. The second end section is dimensioned for insertion into a power cable elbow connector and the mid-section is dimensioned to be sealed against an elbow cuff of the power cable elbow connector. The transition shoulder portion includes at least one raised portion protruding radially outwardly from the transition shoulder portion. The raised portion is adapted to force the elbow cuff of the power cable elbow connector to expand in a radially outward direction upon withdrawal of the second end section from the power cable elbow connector, thereby venting a cavity formed between the bushing insert and the power cable elbow connector.
