Abstract

Abstract A circuit continuity tester for automotive circuits and the like features a simplified wire stabilizing and piercing means which prevents the wire from shifting as the pointed piercing element enters the same. The point of the piercing element is protected. A long bearing contact surface is provided between the piercing rod and the wire stabilizer. The structure is simplified, durable and economical.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 217 words
A circuit continuity tester comprising a body portion comprised of a flat plate having a pair of flanges extending from said plate at the ends thereof, said plate forming a main web and said flanges forming two side webs and cooperating to provide a substantially rigid channel member, a conductive rod projecting from one of the flanges of the channel member outwardly therefrom and having a pointed terminal, a sleeve of substantial length slidable upon the rod, a stabilizing head rigidly secured to the sleeve comprised of a flat plate extending parallel to said sleeve along the length of the sleeve and near one side of said rod and having a forward tapering wire stabilizing seat comprised of two plate sections arranged substantially at right angles defining an apical portion forwardly oF and in advance of said sleeve, and said pointed terminal adapted to position a wire being tested said seat having a clearance opening for the pointed terminal formed therethrough at the apical portion, and a light indicator means including an indicator light bulb electrically connected to said conductive rod and anchored between flanges of the channel member and protected and covered by the main web thereof and a grounding cable anchored to the flange opposite said one flange and being in circuit with said bulb.
Claim 2
Dependent Claim 217 words
