Abstract

This invention relates to collet-type fittings 201 for use in collet-type splices and collet-type dead ends and methods for splicing together two aluminum conductor composite core reinforced cables (ACCC) or terminating one ACCC cable. The collet-type fittings 201 comprise a collet 202 coincident with a collet housing 204 to hold the composite cores. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet 202 and the composite core. After inserting the composite core into the collet 202, a compression element 206 compresses the collet 202. The collet 202 holds the composite core with frictional forces and the collet 202 further compresses and strengthens the hold on the composite core if the composite core pulls the collet 202 further into the collet housing 204.

Claims (10)

1. A fitting for a cable having a composite core comprising:
a collet comprised of one or more sections that form a truncated conical shape, the shape of the collet comprising an outer diameter that increases from a first end to a second end creating an outside slope to slide within a collet housing, the collet further comprising a concentrically oriented lumen, the lumen having a cross-section and length to fit a cross section and length of composite core; and a collet housing having a first open end to allow the collet to fit into the collet housing and a second open end having a smaller internal diameter than the first open end, the housing having a funnel-shaped interior that mirrors the outside slope of the collet to enable the collet to slide into the collet housing without allowing the collet to be forcibly pulled through the second open end of the collet housing.
2. A fitting according to claim 1, wherein tension applied to the composite core in the direction of the second open end pulls the collet into the collet housing applying a compressive force to the collet causing compression of the composite core along the length of the lumen.
3. A fitting according to claim 1, wherein the fitting further comprises an implement that engages with the first open end of the collet housing to enable connection to a second collet housing.
4. A fitting according to claim 3, wherein the implement that engages with the first open end of the collet housing acts to drive the collet into the housing and initiate compression of the collet against the composite core.
5. A fitting according to claim 1, wherein the collet housing comprises a rigid material that enables the collet housing to retain its shape when tension is applied to the composite core and the collet is pulled into the collet housing.
6. A fitting according to claim 1, wherein the collet comprises at least two sections of equal size and shape that fit together to form the collet.
7. A fitting according to claim 1, wherein the collet comprises more than one section, each section identical in size and shape that fit together to form the collet.
8. A fitting according to claim 1, wherein the fitting further comprises a connecting element that couples two or more fittings together to form a splice.
9. A fitting according to claim 1, wherein the fitting further comprises a connector that connects the fitting to a structure to form a dead-end.
10. A fitting according to claim 8, wherein the fitting further comprises an aluminum housing that couples with one or more fittings and electrically connect a conductor of a first cable with a conductor of a second cable.

We claim:
1. A fitting for a cable having a composite core comprising:
a collet comprised of one or more sections that form a truncated conical shape, the shape of the collet comprising an outer diameter that increases from a first end to a second end creating an outside slope to slide within a collet housing, the collet further comprising a concentrically oriented lumen, the lumen having a cross-section and length to fit a cross section and length of composite core; and a collet housing having a first open end to allow the collet to fit into the collet housing and a second open end having a smaller internal diameter than the first open end, the housing having a funnel-shaped interior that mirrors the outside slope of the collet to enable the collet to slide into the collet housing without allowing the collet to be forcibly pulled through the second open end of the collet housing.
2. A fitting according to claim 1, wherein tension applied to the composite core in the direction of the second open end pulls the collet into the collet housing applying a compressive force to the collet causing compression of the composite core along the length of the lumen.
3. A fitting according to claim 1, wherein the fitting further comprises an implement that engages with the first open end of the collet housing to enable connection to a second collet housing.

4. A fitting according to claim 3, wherein the implement that engages with the first open end of the collet housing acts to drive the collet into the housing and initiate compression of the collet against the composite core.
5. A fitting according to claim 1, wherein the collet housing comprises a rigid material that enables the collet housing to retain its shape when tension is applied to the composite core and the collet is pulled into the collet housing.
6. A fitting according to claim 1, wherein the collet comprises at least two sections of equal size and shape that fit together to form the collet.
7. A fitting according to claim 1, wherein the collet comprises more than one section, each section identical in size and shape that fit together to form the collet.
8. A fitting according to claim 1, wherein the fitting further comprises a connecting element that couples two or more fittings together to form a splice.
9. A fitting according to claim 1, wherein the fitting further comprises a connector that connects the fitting to a structure to form a dead-end.
10. A fitting according to claim 8, wherein the fitting further comprises an aluminum housing that couples with one or more fittings and electrically connect a conductor of a first cable with a conductor of a second cable.
