Abstract
Abstract The adapter for use on a compression tool to create a live wire detecting and grounding device comprises a spike engaged to a hydraulically actuated plunger of the tool, the plunger being movable with a jaw defined by a C shaped body of the tool. The spike is conductive, is engaged to a grounding assembly and is used to engage a core of an electrical cable snared within the jaw, causing shorting of a controller for the cable, making the cable currentless. For use with cables of smaller diameter, a reducing sleeve is provided for holding such cables for spike piercing thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
95 words
A live wire detection adapter with grounding capability for use with an hydraulic compression tool, the tool having a jaw of a predetermined height and having hydraulic actuating means for modifying the height of the jaw, the hydraulic actuating means including a plunger within the jaw, the adapter comprising a cable piercing spike mounted by a platform to the plunger of the tool and extending into the jaw of the tool, the spike having a grounding assembly engaged thereto for grounding an electrical high voltage cable pierced by the spike if current is flowing therethrough.
Claim 2
Dependent Claim
95 words
A live wire detection adapter with grounding capability for use with an hydraulic compression tool, the tool having a jaw of a predetermined height and having hydraulic actuating means for modifying the height of the jaw, the hydraulic actuating means including a plunger within the jaw, the adapter comprising a cable piercing spike mounted by a platform to the plunger of the tool and extending into the jaw of the tool, the spike having a grounding assembly engaged thereto for grounding an electrical high voltage cable pierced by the spike if current is flowing therethrough.
Claim 3
Dependent Claim
13 words
The adapter of claim 1 wherein said spike is made of conductive material.
Claim 4
Dependent Claim
35 words
The adapter of claim 1 wherein said grounding assembly comprises at least an electrical cable having a clamp at one end thereof with a second end of the electrical cable being engaged to the spike.
Claim 5
Dependent Claim
36 words
The adapter of claim 1 further including a reducing sleeve which is mountable within the jaw of the compression tool to hold cables of small diameter in place within the jaw for piercing by the spike.
Claim 6
Dependent Claim
36 words
The adapter of claim 4 wherein said reducing sleeve has two flanges extending therefrom, each flange having a notch therein which is positioned and configured to engage a hub on each side surface of the jaw.
Claim 7
Dependent Claim
22 words
The adapter of claim 5 wherein said reducing sleeve comprises a semi-cylindrical member extending across the jaw, a cable being cradled therein.
