US 2003/0193246 A1 · Self-normalling jack with electronically controlled normal circuit or relay

Abstract

A self-normalling jack with an electronically controlled normal circuit or relay comprising a pair of receptacles having a sensing means for sensing the insertion of a plug, the sensing means in communication with an electronic normalling switch or relay, the electronic normalling switch or relay in communication with a paired receptacle such that the electronic normalling switch or relay is located between the source terminal and the upper jack and between the lower jack and the destination terminal. The electronically controlled normalling circuit or relay also connects the source to the destination when no patch cord is inserted into either the upper or lower jack receptacle. When the patch cord is inserted into the upper jack, the source signal is connected to the patch plug. When the patch cord is inserted into the lower jack, the destination signal is connected to the patch plug. Inserting a cord into either jack receptacle disconnects the source from the destination.

Dependent claims

A self-normalling jack having an electronically controlled normal circuit or relay for redirecting an electronic signal from its source to its destination comprising:

a first jack receptacle in communication with a signal source;
a second jack receptacle in communication with a destination source;
an electronic normalling switch in communication with said source signal and said destination signal;
a first sensing means in communication with said first jack receptacle and in communication with said electronic normalling switch or relay;
a second sensing means in communication with said second jack receptacle and in communication with said electronic normalling switch or relay, said first sensing means and said second sensing means signaling said electronic normalling switch to the presence or absence of a patch cord plug positioned in said first jack receptacle or said second jack receptacle, thereby respectively opening or closing said electronic normalling switch or relay for the redirection of said signal.
