Abstract
Abstract A contact insertion and extraction tool for use with multi-pin connectors is provided with an elongate handle having one fixed extension to which a first semi-circular tubular segment is attached and a sliding extension attached to a second semi-circular segment which, when articulated, opposes the longitudinal edges of the first tubular segment. When the segments are abutted against each other a cylindrical, hollow guide is formed which may grasp the lateral surfaces of a lead for insertion or extraction into the insulator block of the connector.

A tool for inserting and withdrawing electrical leads in the body of a multiple lead connector comprising: an elongate handle of substantially rectangular form provided with a longitudinal groove in one lateral surface thereof, said groove communicating through one end of said handle and terminating in an urging surface proximate the other end of said handle, said handle including an arcuate opposing surface formed on one edge thereof proximate said one end and a slot transversely extending through the other edge into the interior of said groove; a substantially rectangular slide received in said groove for longitudinal translation therein, said slide including an end extension projecting through said one end of said handle and having an arcuate seat at the end thereof; a helical spring received between said slide and said urging surface of said groove for urging said slide to extend outwardly from said one end of said handle; a post attached to said slide and aligned to extend through said slot for manual articulation of said slide along a longitudinal motion segment determined by the width of said slot; an elongate plate attached to said handle in alignment over said groove for retaining said slide in the interior thereof, said plate including an end projection extending along said slide beyond said one end of said handle and having an arcuate end segment aligned in opposition to said seat; a first and second tubular section respectively fixed to said arcuate end segment and to said arcuate seat to extend in cantelever therefrom, said first and second sections cooperating to form a tubular structure conformed to retain said electrical leads when opposed relative each other and to release said leads when separated, said tubular sections being aligned to guide said leads over said arcuate opposing surface to be compressed thereat by the fingers of a user of said tool; and detent means connected to said slide for fixing the sliding extension thereof in said opposing and separated alignments.
