Abstract

A conductor tester including two contour-identical parts of a main unit and a remote unit is used to test and indicate present condition of conductors. Both the main and the remote units are formed at two ends with high and low raised portions that are provided with fastening means for the two units to detachably connect to each other to form a compact unit. The high and low raised portions are provided at side walls with notches that are electrically connected to internal circuits of the main and the remote units, and at inner walls between the high and low raised portions with light-emitting diodes. By connecting the main and/or the remote unit at two notches thereof to two ends of one or more conductors, internal circuits of the main and/or the remote unit are brought to contact with the conductor or conductors, causing one or more of the light-emitting diodes to light to indicate present conditions of the conductor or conductors, such as short circuit, open circuit, reverse connection, wrong connection, etc.

Claims

1. A conductor tester comprising two contour-identical parts of a main unit and a remote unit, both of said main and said remote units being respectively formed at two ends thereof with high and low raised portions, said high raised portions being provided at top inner middle points with fastening means and said low raised portions being provided at bottom outer middle points with catchers so that said main unit can be turned upside down to superpose on and connect to said remote unit to form a compact unit by engaging said fastening means on one of said two units with said catchers on the other said unit;

said high and said low raised portions respectively being provided at side walls thereof with notches that are electrically connected to respective internal circuits of said main and said remote units; and

an inner wall of each of said main unit and said remote unit having at least one row of light-emitting diodes provided thereon between said high and said low raised portions;

whereby by separately connecting said main and said remote units at notches thereof to conductors at two remotely spaced ends of a wiring system, said internal circuits of said main and said remote units are brought into contact with said conductors, and at least one of said light-emitting diodes lights to indicate different conditions of said conductors connected to said main and said remote unit.
