Buried-type splice case

Claim 2

A buried-type splice case comprising a dielectric base having a pair of spaced openings for receiving the opposite runs of a loop of cable that has a metallic grounding shield and an insulating sheath surrounding the grounding shield said base being split along a parting region that passes substantially through the centers of said openings to provide cooperating base sections, said base sections having additional openings for receiving service wires, means sealing said pair of openings and additional openings with the cable and service wires extending therethrough, said base sections cooperating to provide grooves at the parting region receiving sealing material, there being grooves laterally outwardly of said pair of spaced openings and a groove intermediate said pair of openings, means outwardly of sAid outward grooves clamping the base sections together, means secured to said base for grounding the metallic shield on the cable; said grounding means including an inner clamp surrounded by the grounding shield and projecting therethrough, and an outer clamp engaging the inner clamp and said insulating sheath; and bracket means also mounted on said base supporting the loop of cable remote from said base.

Claim 3

A buried-type splice case according to claim 1 including ribs on the walls of said pair of spaced openings, and sealing means disposed around each cable run and engaged by said ribs whereby to form the seals at said pair of spaced openings.

Claim 4

A buried-type splice case according to claim 1 further including a cover, and means peripherally and removably sealing the cover to said base to enclose said loop of cable.

Claim 5

A buried-type splice case comprising a dielectric case of moisture impervious material, said base having a pair of base sections each with adjacent recesses, the base sections being separably secured together such that the recesses form two adjacent openings receiving the opposite runs of a loop of cable having a metallic grounding sheath, an outer insulating sheath surrounding the grounding sheath, an inner insulating sheath surrounded by the grounding sheath, and core wires surrounded by the inner insulating sheath; inner sheath clamping means engaging the inside of said grounding sheath, outer sheath clamping means engaging the outer sheath and said inner sheath clamping means, said outer sheath clamping means comprising opposed cooperating members that provide side-by-side recesses surrounding the cable runs, means drawing said members together and tightly around the cable runs and providing a firm mechanical and electrical contact of said outer sheath clamping means with said inner sheath clamping means, means securing said outer sheath clamping means to one of said base sections, said securing means providing a connection for grounding said sheath through said outer sheath clamping means, a bracket in conductive connection with said outer sheath clamping means and having an end remote from said base supporting the core wires of the loop of cable, said base sections each having additional openings receiving service wires for splicing with said core wires, said service wires having a grounding shield, means forming a ground connection between the service wire shield and said bracket, means sealing said two adjacent openings and said additional openings, means forming a seal at the juncture of said base sections, and a cover removably attached to said base and enclosing the core wires of the loop of cable.

Claim 6

A buried-type splice case comprising a dielectric case of moisture impervious material, said base having a pair of base sections each with adjacent recesses, the base sections being separably secured together such that the recesses form two adjacent openings receiving the opposite runs of a loop of cable having a metallic grounding sheath, an outer insulating sheath surrounding the grounding sheath, an inner insulating sheath surrounded by the grounding sheath, and core wires surrounded by the inner insulating sheath; inner sheath clamping means engaging the inside of said grounding sheath, outer sheath clamping means engaging the outer sheath and said inner sheath clamping means, said outer sheath clamping means comprising opposed cooperating members that provide side-by-side recesses surrounding the cable runs, means drawing said members together and tightly around the cable runs and providing a firm mechanical and electrical contact of said outer sheath clamping means with said inner sheath clamping means, means securing said outer sheath clamping means to one of said base sections, said securing means providing a connection for grounding said sheath through said outer sheath clamping means, a bracket in conductive connection with said outer sheath clamping means and having an end remote from said base supporting the core wires of the loop of cable, said base sections each having additional openings receiving service wires for splicing with said core wires, said service wires having a grounding shield, means forming a ground connection between the service wire shield and said bracket, means sealing said two adjacent openings and said additional openings, means forming a seal at the juncture of said base sections, and a cover removably attached to said base and enclosing the core wires of the loop of cable.

Claim 7

A buried-type splice according to claim 4 in which the means forming the seal at the juncture of the two sections including grooves at said juncture, and sealing material in said grooves.
