Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 185 words
An interceptor plug for intercepting an phone signal available at a standard electrical jack comprising: (A) a central shaft of electrically conductive material having an integral interior tip, said tip being eccentric relative to said central shaft; (B) an electrically insulating sleeve concentric and coextensive with said central shaft except for said tip; (C) an electrically conductive sleeve concentric and coestensive with and exterior to said insulating sleeve except that the length of said conductive sleeve is adjusted to expose said insulating sleeve at said interior tip end; (D) a positioning sleeve of electrically insulating material surrounding the combination of said central shaft, insulating sleeve and conductive sleeve so as to insulate said conductive sleeve from the body of said jack; (E) a grip of nonconductive material firmly affixed to said positioning sleeve, said grip surrounding two conductive wires running lengthwise through said grip and extending beyond the ends of said grip; and, (F) a connection means for connecting one of said wires to said exterior end of said central shaft and the other of said wires to said exterior end of said conductive sleeve.
