  • Publication number: 20090111324
    Abstract: A separable connector shield housing includes a layer of conductive material disposed at least partially around a layer of non-conductive material. The layers are molded together. For example, the conductive material can be overmolded around the non-conductive material, or the non-conductive material can be insert molded within the conductive material. The molding results in an easy to manufacture, single-component shield housing with reduced potential for air gaps and electrical discharge. The shield housing defines a channel within which at least a portion of a contact tube may be received. A contact element is disposed within the contact tube. The conductive material substantially surrounds the contact element. The non-conductive material can extend along an entire length of the contact tube and other components, or it may only extend partially along the contact tube. The non-conductive material can include an integral nose piece disposed along a nose end of the contact tube.

  • Publication number: 20090088014
    Abstract: A loadbreak connector system and methods for visible break include first and second mating connector assemblies configured to make or break an electrical connection under energized circuit conditions, the first and second mating connectors selectively positionable relative to one another. One of the first and second mating connectors includes an arc follower, and the other of the first and second mating connectors includes an arc interrupter. The arc interrupter is configured to receive the arc follower, and the first and second meting connectors are positionable in an disconnected position wherein the arc follower remains engaged to and is located within the arc interrupter. Arc energy is distributed among multiple locations to reduce arc intensity.

  • Publication number: 20090081896
    Abstract: A separable loadbreak connector system includes mating electrical connectors. At least one of the electrical connectors includes an electrically-resistive housing having a generally conically-shaped interior bore. A semiconductive insert is disposed within a portion of the interior bore and presents an inner radial surface that defines a generally conically-shaped recess. An elongated probe assembly is disposed within the housing and includes a probe and a sheath of insulative material disposed over at least a portion of a length of the probe. A portion of the sheath extends in a radially outward direction from a base of the probe. An electrically-resistive insulative layer extends from the conically-shaped interior bore, along at least a portion of the inner radial surface of the semiconductive insert. The insulative layer extends radially inwardly in overlapping engagement with a portion of the sheath.

  • Publication number: 20090029606
    Abstract: An electrical connector for connecting to an electrical apparatus within a high power circuit includes an electrical contact and an enclosure. The electrical contact is configured to connect to a bushing of an electrical apparatus within a high power circuit. The electrical contact extends along a first direction from a coupling region. The enclosure extends from the coupling region in a second direction that is nonparallel to the first direction. The enclosure includes two or more electrical devices, with each electrical device being connected to the electrical contact within the coupling region and providing a current path from the electrical apparatus to at least one external coupling device within the high power circuit.

  • Patent number: 7470131
    Abstract: An electrical device includes a body, an electrical contact having a first end for electrically coupling to an electrical apparatus and a second end within the body, and a conductor electrically coupled to the second end of the electrical contact. The electrical device also includes an access region defining a cavity and a surge arrester that electrically couples to the conductor through the access region. The cavity provides access to an interior of the electrical device. The access region may include an insulating projection extending from an insulating body of the electrical device and a conductive cover surrounding the insulating projection. The insulating projection defines the cavity. The conductive cover is electrically isolated relative to a conductive shell that surrounds the insulating body.

  • Publication number: 20080301937
    Abstract: In one aspect, an electrical connector assembly can be removably coupled to a second electrical connector assembly. The electrical connector assembly includes an elastomeric insulative layer and a rigid conductive sleeve disposed within the insulative layer. One or both of the rigid conductive sleeve and the insulative layer have interior surfaces that define an opening. A conductive contact is disposed within the opening and a conductive or semi-conductive exterior layer at least partially covers the insulative layer. The rigid conductive sleeve is configured to act as a voltage shield and the conductive or semi-conductive exterior layer is configured to act as a ground shield.

  • Publication number: 20080299818
    Abstract: A jacket sleeve with grippable tabs provides protection to exposed portions of cable that are connected to an electrical connection. The jacket sleeve can be made as part of the electrical connector or may be connected subsequent to its creation through the use of glues or other adhesives. The jacket sleeve can be made of a material that is more pliable than the electrical connector, making it easier for a lineperson to place the sleeve over an exposed portion of cable. The jacket sleeve can include holes or slots either in the sleeve or in tabs that are attached to the sleeve. A lineperson can place one or more fingers into each hole or slot in order to get a better grip on the sleeve and pull the sleeve over the exposed portion of cable with less slippage and effort on the part of the lineperson.
