  • Patent number: 7870668
    Abstract: An electrical connector includes a sleeve defining an axis and a contact assembly inserted in the sleeve, the contact assembly including pieces that move axially relative to one another during a fault close operation. An interface between the sleeve and the contact assembly is configured to permit replacement of the contact assembly without replacing the sleeve.
    Type: Grant
    Filed: January 16, 2009
    Date of Patent: January 18, 2011
    Assignee: Cooper Technologies Company

  • Publication number: 20070108164
    Abstract: Insulated vacuum switchgear and active switchgear elements therefor are provided with a rigid support structure mechanically isolating a vacuum insulator from axial loads in use without reinforcing or insulating encapsulations. At least one of the elastomeric insulating housing and the support structure directly contacts an outer surface of the insulator. Systems and methods for assembling the switchgear are also provided.

  • Publication number: 20070026713
    Abstract: A separable loadbreak connector and system includes a connector having a contact tube with an axial passage therethrough, and a contact member slidably mounted within the axial passage and movable therein during a fault closure condition. The contact member is axially movable within the passage with the assistance of an arc quenching gas during the fault closure condition, and a shock absorbent stop element is mounted to the contact tube and limiting movement of the contact member in the fault closure condition.

  • Publication number: 20060148292
    Abstract: A separable insulated connector provides a current path for high-energy distribution between a power transmission or power distribution apparatus and an elbow connector. As gases and conductive particles exit the separable insulated connector during loadbreak switching, the gases and particles are re-directed away from a mating electrode probe and diverted along a path non-parallel to the electrode probe.

  • Publication number: 20020168887
    Abstract: Apparatus for reducing the risk of flashover during loadbreak operations of insulated separable connectors. A substantial airtight seal is prevented between the collar of the bushing insert and the cuff of the mating component. The connection is vented to break any adhesion between the bushing insert and the mating component cuff and to provide a chamfered airway for atmospheric airflow during removal of the mating component. A latch ring is reformed to include at least one raised edge about its outer diameter. Each raised edge has the shape of a sharply angled ramp and extends outward. There may be four or six raised edges.
