Protector module test set

Claim 1

A test set for a telephone connector protector (17) module used in a telephone connector (11) for cable terminations, said telephone connector (11) having a multiplicity of five prong protective modules (17) plugged therein, each of said modules having a tip and a ring circuit (29, 31) with a tip, ring, and ground, long prong (21, 23, 25), and a tip and ring short prong (27, 28), one heat coil (33, 35) and a shunt switch (37, 39) coupled to the tip and ring circuits and the ground prong, said test set comprising in combination; a. a rectangular box-like housing (55), with a front panel (59); b. a receptacle (61) in the center of said panel for receiving a five prong module having tip ring and ground long plugs (21, 23, 25) and tip and ring short plugs (27, 28); c. tip, alarm, and ring lamp sockets and lamps (63, 65, 67) in line in said panel above said receptacle (61), a clear switch (73), pilot lamp (69), power switch (71), in line in said panel below said receptacle; d. a power line (75) connected to said housing (55) with a plug in unit (77); e. a power line circuit connected to said plug-in unit including said power switch (71), a transformer primary and secondary (81), a pilot lamp (69) in parallel with said transformer primary and a fuse (79); f. first and second side lines (85, 83) connected to said secondary, said first side (85) terminating in tip and ring short plugs of said receptacle (61); g. a tip circuit connected between said second side (83) and said tip long plug having said tip lamp (63) in series therein; h. a ring circuit connected between said second side (83) and said ring long plug having said ring lamp (67) in series therein; i. an alarm circuit connected between said second side and said ground long plug having said alarm lamp (65) and a junction in series therein; and, j. a clear circuit connecting said second side and said junction having said clear switch (73) and a high value resistor therein, whereby, when a module to be tested is placed in said receptacle and the power switch is closed, the ring and tip lamps will light up if the module is in good order, the alarm light will not light up if there is no short, and if the clear switch is pressed the circuit closing should clear carbon dust in the modules, while if the tip or ring lamps fail to light or if the alarm lamp remains lit, the module is defective.
