Abstract
Abstract A cathode for an electrochemical apparatus, such as an electroplating barrel, is provided which is more securely attached to the end of the electrical conductor cable in order to better resist detachment caused by chemical erosion and/or impact with work products being agitated or tumbled in the barrel. The combination of a cathode and a length of insulated electrical conductor cable extending into the electroplating barrel is referred to in the art as a dangler. The subject dangler assembly comprises an insulated conductor cable having one end stripped of insulation and inserted into a compressible sleeve. A pin is driven into the sleeve encased end of the conductor concentric therewith. A metal cylinder, referred to in the art as a contactor, is then concentrically fitted over the sleeve encased conductor end and compressed, usually by rolling, to place the sleeve and conductor end in compression about the pin. This assembly has been found to have longer life and greater current carrying capacity than prior art danglers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
55 words
A dangler assembly for an electrochemical installation comprising: a. an electrical conductor, b. a metallic sleeve encasing one end of said conductor, c. a metallic pin embedded in said end concentric therewith, and, d. a contactor encasing said metallic sleeve in compression, whereby said conductor is compressed between said metallic sleeve and said concentric pin.
Claim 2
Dependent Claim
55 words
A dangler assembly for an electrochemical installation comprising: a. an electrical conductor, b. a metallic sleeve encasing one end of said conductor, c. a metallic pin embedded in said end concentric therewith, and, d. a contactor encasing said metallic sleeve in compression, whereby said conductor is compressed between said metallic sleeve and said concentric pin.
Claim 3
Dependent Claim
101 words
A dangler assembly for an electrochemical installation comprising: a. an insulated electrical conductor having at least one end stripped of insulation, b. a metallic sleeve adapted to fit snugly over and encase the uninsulated end of said conductor, c. a metallic pin embedded in the center of said uninsulated end and extending coaxially therewith, d. a metal contactor having a blind coaxial hole in one end to form a second sleeve telescoped over said uninsulated end and a portion of the insulated conductor in pressure gripping contact therewith, whereby said uninsulated conductor is gripped between said metallic sleeve and said pin.
Claim 4
Dependent Claim
101 words
A dangler assembly for an electrochemical installation comprising: a. an insulated electrical conductor having at least one end stripped of insulation, b. a metallic sleeve adapted to fit snugly over and encase the uninsulated end of said conductor, c. a metallic pin embedded in the center of said uninsulated end and extending coaxially therewith, d. a metal contactor having a blind coaxial hole in one end to form a second sleeve telescoped over said uninsulated end and a portion of the insulated conductor in pressure gripping contact therewith, whereby said uninsulated conductor is gripped between said metallic sleeve and said pin.
Claim 5
Dependent Claim
153 words
The dangler assembly for an electrochemical installation comprising: a. an elongated electrical conductor, b. an insulating sheath of electrically non-conductive material enclosing the intermediate portion of said electrical conductor and terminating short of at least one end of said conductor, c. a metallic conductor sleeve adapted to fit snugly over said one end of said conductor and to extend coterminously with said end from said sheath to the outer axial extremity of said end, d. a metallic pin embedded in the center of said conductor and extending axially from said sheath to beyond the said outer axial extremity of said end, and e. a contactor having a blind end sleeve snugly telescoped over said sleeve encased conductor end and an adjacent portion of said insulating sheath in pressure gripping contact therewith, whereby said blind end sleeve compresses said conductor sleeve causing said conductor to be gripped between said conductor sleeve and said pin.
