Abstract

A system for locating corresponding ends of a patch cord used to conduct a signal between a first receptacle and a second receptacle. The system includes a cable having a main signal transmission means and a pair of electrically conductive members extending along the length of the cable. A first connector is attached to one end of the cable and a second connector is attached to the other end of the cable. The first and second connectors are adapted to removably mate with the first and second receptacles, respectively. The first connector has a pair of leads associated therewith. Each of the leads is connected to and corresponds to one of the conductive members. An electrical indicator is attached to the first receptacle. The indicator is electrically connected to the pair of leads when the first connector is mated to the first receptacle. A power supply is used to apply current through the conductive members so that upon application of the current, the indicator is activated.

9. The system of claim 8 wherein said adapter body leads are in the form of prongs and said connector leads are disposed in apertures formed in said connector for receiving said prongs.

10. The system of claim 1 further comprising:

a pair of leads associated with said second connector, each second connector lead connected to and corresponding to one of said conductive members; and

a second electrical indicator attached to the second receptacle, said second indicator electrically connected to said second connector leads when said second connector is mated to the second receptacle;

wherein application of said current to said first and second conductive members results in activation of both said first and second indicators.

11. An indicator assembly adapted for attachment to a patch cord receptacle, the receptacle configured to mate with a patch cord connector disposed on one end of a cable having a main signal transmission member, the connector having two electrical leads that are electrically connected to corresponding conductive members that extend along the cable, the indicator assembly comprising:

an indicator module having an electrical indicator disposed therein that indicates the presence of a current through the indicator, said module having a pair of leads connected to the electrical indicator that are located to contact the pair of leads of the connector when the connector engages the receptacle; and

means for attaching said indicator module to the receptacle.

12. The indicator assembly of claim 11 wherein said attaching means includes a pair of spaced outwardly deformable tabs extending from one side of the receptacle, said module received between said tabs in a snapping action to attach said module to the receptacle.

13. The indicator assembly of claim 11 wherein said attaching means includes a shroud for surrounding both the receptacle and said module so that said module is attached to the receptacle.

14. The indicator assembly of claim 13 wherein said module snaps into said shroud and said shroud snaps onto the receptacle.
