Abstract
This invention relates to 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 use a collet inside a collet housing to hold the composite cores. The composite cores can be stripped of the aluminum conductor to provide a bond between the collet and the composite core. After inserting the composite core into the collet, a compression implement compresses the collet. The collet holds the composite core with frictional forces and the collet further compresses and strengthens the hold on the composite core if the composite core pulls the collet further into the collet housing.

A collet-type splice to connect a first aluminum conductor composite core reinforced cable and a second aluminum conductor composite core reinforced cable, each cable having a composite core surrounded by a conductor, comprising:
- a. two or more collet-type fittings, each fitting comprising:
- i. a collet having at least one lumen to mate with the composite core from the cable;
- ii. a collet housing, wherein the collet housing mates with the collet to compress the collet, and wherein the collet housing has an opening to expose the at least one lumen to enable the collet to mate with the composite core of the cable;
- and
- iii. a compression implement that couples with the collet housing, wherein the compression implement compresses the collet inside the collet housing, and wherein compressing the collet exerts a compressive and frictional force on the composite core of the cable;
- and
- b. at least one connecting rod that couples the two or more collet-type fittings together.
A method to splice together a first aluminum conductor composite core reinforced cable and a second aluminum conductor composite core reinforced cable, each cable having a composite core surrounded by a conductor, comprising:
- a. exposing a composite core of a first cable;
- b. exposing a composite core of a second cable;
- c. inserting the composite cores of the first and second cables into separate collet-type fittings, the insertion process comprising:
- i. inserting the composite core of each cable into a first and a second collet;
- ii. compressing each collet to hold frictionally each composite core;
- and
- d. coupling a connecting rod to each of the separate collet-type fittings to hold the collet-type fittings together.
A spliced electrical cable, comprising:
- a. a first span of aluminum conductor composite core reinforced cable, the cable having a composite core surrounded by a conductor;
- b. a second span of aluminum conductor composite core reinforced cable, the cable having a composite core surrounded by a conductor;
- c. a splice, comprising:
- i. a first collet-type fitting coupled to the first span of aluminum conductor composite core reinforced cable;
- ii. a second collet-type fitting coupled to the second span of aluminum conductor composite core reinforced cable;
- iii. wherein each collet-type fitting comprises:
- (1) a collet having at least one lumen to mate with the composite core from the cable;
- (2) a collet housing, wherein the collet housing mates with the collet to compress the collet, and wherein the collet housing has an opening to expose the at least one lumen to enable the collet to mate with the composite core of the cable;
- and
- (3) a compression implement that couples with the collet housing, wherein the compression implement compresses the collet inside the collet housing, and wherein compressing the collet exerts a compressive and frictional force on the composite core of the cable;
- and
- iv. a connecting device that couples the first collet-type fitting to the second collet-type fitting.
