Splice enclosure for electrical wires

Claim 2

An enclosure for providing environmental sealing, insulating, and strain relief of a splice joining electrical wires that are surrounded by insulation which is stripped away for the splice characterized by: (a) a molded housing comprising two halves having opposing internal faces and containing a plurality of cavities which are the mirror image of cavities in the other half, a first pair of said cavities defining, when said halves are joined, a wire conductor void for receiving said splice and second and third pairs of cavities each defining, insulation receiving void for grasping the perimeter of insulation on each side of said splice; (b) hinge means joining the two halves on one side of the cavities for allowing the two halves to be pivotally joined together; (c) mastic sealer adhered to at least a portion of each internal face for providing a seal around the insulation and the splice as the two halves are joined; and (d) cooperating locking means for locking said two halves together.

Claim 3

The enclosure of claim 1, further characterized in that said mastic sealer is adhered to the internal faces of said housing in said second and third pair of cavities.

Claim 4

The enclosure of claim 2 further characterized by: release paper positioned to cover at least a portion of the mastic sealer to protect the mastic sealer prior to application of the enclosure to the splice.

Claim 5

The enclosure of claim 2 further characterized in that the hinge means comprises a living hinge.

Claim 6

The enclosure of claim 3 further characterized in that said living hinge is integrally formed with said two halves.

Claim 7

The enclosure of claim 1 further characterized in that said locking means comprises are elevated tab on one of said halves and an aperture on the second of said halves for receiving and engaging said tab.

Claim 8

The joint described in claim 6 further characterized in that said mastic sealer is adhered to the internal faces of said housing in said insulation voids.

Claim 9

An electrical joint which comprises: (a) a plurality of electrical wires each having a central conductor and surrounding insulation and said central conductors being joined to form a splice, (b) a preformed housing made of injected molded plastic, the housing having internal and external faces, edges, and a longitudinally extending living hinge means defining two housing halves that swing together around the hinge, (c) a plurality of mirror imaged cavities located equidistant from the living hinge means having a pair of insulation voids of a predetermined radius based on the radius of the wire including insulation for receiving and grasping the perimeter of the insulations of the wires, said insulation voids being connected by a conductor void for receiving the conductors and the conductor splice; (d) mastic sealer adhered to at least a portion of the internal faces of the housing for providing a seal around the insulation and the splice formed when the two halves are joined, and (e) means for locking the enclosure about the conductor splice and the insulation of the electrical wires to secure the insulations of the wires to the housing, whereby the housing in combination with the means for locking the enclosure and the mastic sealer will allow potential loads to be passed from one wire to another wire without passing through the connector splice connecting said wires and the joint will be environmentally sealed and insulated.

Claim 10

An electrical joint which comprises: (a) a plurality of electrical wires each having a central conductor and surrounding insulation and said central conductors being joined to form a splice, (b) a preformed housing made of injected molded plastic, the housing having internal and external faces, edges, and a longitudinally extending living hinge means defining two housing halves that swing together around the hinge, (c) a plurality of mirror imaged cavities located equidistant from the living hinge means having a pair of insulation voids of a predetermined radius based on the radius of the wire including insulation for receiving and grasping the perimeter of the insulations of the wires, said insulation voids being connected by a conductor void for receiving the conductors and the conductor splice; (d) mastic sealer adhered to at least a portion of the internal faces of the housing for providing a seal around the insulation and the splice formed when the two halves are joined, and (e) means for locking the enclosure about the conductor splice and the insulation of the electrical wires to secure the insulations of the wires to the housing, whereby the housing in combination with the means for locking the enclosure and the mastic sealer will allow potential loads to be passed from one wire to another wire without passing through the connector splice connecting said wires and the joint will be environmentally sealed and insulated.

Claim 11

The joint as set forth in claim 8 and further comprising: release paper positioned to cover at least a portion of the mastic sealer to protect the mastic sealer prior to application of the enclosure to the splice.

Claim 12

The joint as set forth in claim 8 wherein the means for locking the enclosure comprises: a plurality of locking tabs projecting from one of the internal faces of the preformed housing and located in close proximity to one of the edges; and corresponding cutouts in the preformed housing located in close proximity to the opposite edge for receiving the locking tabs.

Claim 13

The joint according to claim 10, further characterized in that at a position adjacent each insulation void there is a said insulation void for holding the two halves together.
