Abstract
A protective cover for use particularly in a sealed splice of electrical cables comprises a generally cylindrical, elongate tubular member having a wall the ends of which are in overlapping relation over a circomferential portion of the tubular member. A groove extends radially into the inner circumferential surface of the tubular member and axially therealong at least for a portion of the length of the member. It is preferred that the tubular member be formed from a pre-contoured sheet of rubber-like material, the inner contoured sheet surfaces being coated with a sealing material.
Claims31
A protective cover for an electrical connection, comprising a generally cylindrical, elongate tubular member of resilient, non-conductive material having a wall the ends of which overlap over a circumferential portion of said member, the facing surfaces of said overlapping wall portion being relatively smooth, the inner circumferential surface of said member having a recess extending radially therein and axially along at least a portion of the longitudinal extent of said member, and a sealant on a relatively smooth wall surface portion of said member at the overlapping portion of said wall.
A cable splice protector, comprising a pre-contoured sheet of flexible, non-conductive material formed into a generally cylindrical, elongate tubular member, the free ends of said sheet being in overlapping relation over a circumferential portion of the member, the surface portion of said sheet defining the inner circumferential surface of said member having therewithin a curved groove extending axially along at least a portion of the longitudinal extent of said member, said overlapped free end of said sheet having on its inner surface an arcuate surface portion coextending axially with said groove, said arcuate portion having a radius of curvature different from that of said groove such that said arcuate portion intersects the outer surface of said sheet at said overlapped free end forming thereby a relatively sharp edge thereat.
A sealed splice of electrical cables, comprising:
- means connecting exposed conductors of the cables;
- a resilient elongate cover of electrically insulating material positioned over said connecting means and said exposed conductors, a portion of said cover extending over said electrical cables, said cover comprising a generally cylindrical, tubular member having a wall the ends of which are in circumferentially overlapping relation, the inner circumferential surface of said member having a groove extending radially therewithin and axially along at least a portion of the longitudinal extent of said member, a wall portion of said groove engaging axially one of said cables and a portion of the inner circumferential surface of said tubular member engaging axially another one of said cables;
- and
- means for radially compressing said cover on said cables.
A sealed splice of electrical cables wherein a plurality of smaller cables are electrically connected to a larger cable, the larger cable having an axial portion of its outer insulation removed to expose conductors for connection to conductors of the smaller cables, the smaller cables extending coaxially with said larger cable on both sides of said exposed portion of said larger cable, said splice comprising:
- means connecting exposed conductors of said smaller and larger cables;
- a layer of electrically insulating material covering said connecting means and said exposed conductors and on the outer insulation of said larger cable adjacent both sides of the exposed portion thereof;
- a flexible, non-conductive elongate cover positioned over said layer, said cover comprising a generally cylindrical tubular member having a wall the ends of which circumferentially overlap, the inner circumferential surface of said tubular member having a plurality of grooves extending radially therewithin and along at least a portion of the longitudinal extent of said tubular member, said grooves being spaced about the longitudinal axis of said tubular member in an arc of revolution and engaging the smaller cables, a portion of the inner circumferential surface of said tubular member engaging a portion of the insulating layer around said larger cable, said smaller cables contacting a portion of the insulating layer around said larger cable around a peripheral portion thereof;
- a coating of sealing material on the inner circumferential surface of said tubular member, on the walls of said grooves and on an overlapping wall surface;
- and
- means radially compressively engaging said cover for effecting sealed contact between said cover and said layer and between said overlapping wall of said cover.
A protective cover for an electrical connection, comprising a generally cylindrical, elongate tubular member of resilient, non-conductive material having a wall the ends of which overlap over a circumferential portion of said member, the inner circumferential surface of said member having a plurality of recesses extending radially therein and axially along at least a portion of the longitudinal extent of said member, said recesses being spaced radially about a first longitudinal axis, and a cavity defined by a portion of the inner circumferential surface, said cavity being centered about a second longitudinal axis spaced from said first axis.
