Electrical conductor identifying assembly

Claim 1

An identifying assembly 10 designed to identify remotely located ends of individual elongated electrical conductors 18, wherein the opposite ends of said conductors are disposed in a large group of such conductors, said assembly comprising: (a) a control unit 12 attachable to one end of one elongated electrical conductor 18' of a plurality of commonly disposed conductors 18 and including electrical power source 44 connected to said control unit 12. (b) a plurality of indicator units 14, each being individually attachable to an opposite end of one 18' of a plurality of commonly disposed conductors 18 and structured to receive current passing through the correspondingly attached conductor, (c) each of said indicator units 14 comprising a first signal means 30 and 32 for indicating current flow to said indicator unit through the conductor from said control unit, (d) said first signal means of said indicator units 14 comprising an illuminated signal structure 30 visually discernible when activated by current flow through the conductor 18' attached to said indicator unit 14, said illuminated signal structure 30 comprising a light emitting diode, (e) said first signal means of said indicator unit 14 further comprising an audio signal structure 32 audibly discernible when activated by a current flow through the conductor attached to said indicator unit, (f) said control unit 12 comprising control circuitry 36 including a switch assembly 24 connected in current controlling relation between said power source and a remainder of said control circuitry, whereby activation of the entire circuitry is facilitated, (g) said control unit 12 and one of said indicator units 14 being electrically interconnected through respective attachment to opposite ends of the conductor 18' and said control circuitry structured to deliver current flow to said indicator unit through the conductor from said power source 44, (h) said control unit further comprising a second signal means 21 and 22 including a first control signal structure 21 interconnected to said control circuitry 36 and structured for activation upon current flow passing from said power source 44 through the control circuitry 36 and the attached conductor 18' and to said indicator unit 14, (i) said second signal means further comprising a second control signal structure 22 interconnected to said control circuitry 36 and structured for activation upon current flow directed thereto and failure of current flow to said indicator unit 14, the latter condition being indicative of a short circuit condition between said power source 44 and said indicator unit 14, (j) said first control signal structure 21 and said second control signal structure 22 comprising a light emitting diode structured and disposed for visual observation upon activation thereof, (k) the current flow through the conductor 18' and between said control unit 12 and said indicator unit 14 being evidenced by activation of said first signal means 30 and 32 and distinguishing the end of the conductor 18' attached to said indicator unit 14 and identifying the conductor 18' from a plurality of other similarly placed conductors 18, and (l) said control unit further comprising noise reduction means 23 interconnected to said control circuitry 36 for reducing noise within said circuitry and thereby substantially increasing the maximum length between said opposite ends of the conductor 18' to be identified while still permitting the activation of said first and second signal means.
