Cable tester with first and second interengaging test modules

Claim 1

A cable tester device comprising: a first and second module, said modules each having a main face, each main face being companionately sized and configured for mating interengagement with each other in snug nested relation, each of said main faces having a bank of connector adapters composed of male and female pin means to connect one of the modules to each end of a cable provided with a companionate connector, said banks of pin means being composed of mating pins electrically in engagement with one another when said modules are interengaged in nesting relation with one another, a circuit means in said first module including a conductor electrically connected to each pin and electrically in series with a separate light emitting diode and resistor in series with one another, all of said conductors including said light emitting diodes and resistors in series therewith being in parallel with one another and in series with a main conductor circuit, said main conductor circuit including a battery in series with said parallel conductors to simultaneously energize the same and switch means for controlling energy flow from said battery through said circuit means of said first module; the pin means of said second module being arranged in an array corresponding to the pins of said first module and said pin means of said array of said second module being in a pattern of odd and even pin means with an odd pin means between each even pin means, and a circuit in said second module connecting each adjacent odd and even pin through a light emitting diode in series therewith and comprising 24 separate circuits.
