Abstract:
1. A group wiring device for facilitating wire pair identification, said group wiring device comprising: a plurality of wire pair receptacles capable of receiving plugs, each receptacle further comprising at least two contacts each connecting with a conductive wire; and a plurality of testing circuits each testing circuit coupling between said conductive wires of said contacts of one receptacle and further comprising: at least one light emitting means connected on said testing circuit for emitting light when a testing voltage is applied to said light emitting means; and at least one switch mechanism connected with the light emitting means on said testing circuit and being switchable between an “OPEN” status and a “CLOSE” status; wherein, the switch mechanism remains on the “CLOSE” status when there is no plug received in the receptacle, and the switch mechanism switches to the “OPEN” status when there is a plug mated with the receptacle; wherein the switch mechanism comprises at least one metal stick having one end thereof connected with the light emitting means, the contact is a flexible contact pin, one end of the pin is coupled with the light emitting means, while the other end is a bendable and contactable with the metal stick of the switch mechanism the bendable end of the pin keeps contact with the metal stick when no plug is received in the receptacle so as to make the circuit of the light emitting means to be a close loop, and when the plug is plugged in the receptacle, the bendable end of the pin is pressed and bended by the plug and thus lose contact with the metal stick so as to make the circuit of the light emitting means to be an open circuit.
