ABSTRACT:
A double-barreled tool for inserting and extracting electrical contacts includes an inner barrel and an outer barrel, the inner barrel being coaxial with the outer barrel and fully retractable therein. Each barrel has an elongated slot which are in alignment with one another. A means is provided for retracting the inner barrel into and extending the inner barrel from one end of the outer barrel. The contacts have lead wires extending therefrom. To extract and electrical contact from its installed position within an insulator body cavity, the contact lead wire is first slipped into the aligned slots of the inner and outer barrels. Then, the tool is guided along the wire and into the cavity, until the outer barrel impacts the dielectric within the cavity at a point at which the cavity narrows. At this juncture, the inner barrel is extended from the other barrel such that the end of the inner barrel approaches the electrical contact, thereby releasing the contact. Once the contact is released, the wire and tool are gripped together and pulled simultaneously from the cavity, thereby extracting the contact from the cavity. Finally, the wire is released from the tool.
