Plug insertion detection circuits and related methods and communications connectors

摘要

Methods of detecting a plug insertion into a plug aperture of a communications connector are provided in which a control signal is transmitted to a control signal input circuit of the connector that includes a reactive coupling element. The control signal is electromagnetically coupled through the control signal input circuit. The electromagnetically coupled control signal is thereafter detected on a first differential pair of conductive paths that are included in the connector. A determination is made that a plug is present in the plug aperture based at least in part on detecting the electromagnetically coupled control signal on the first differential pair of conductive paths.

1. A method of detecting a plug insertion into a plug aperture of a communications connector that includes a plurality of input ports, a plurality of output ports, and a plurality of conductive paths that connect respective ones of the input ports to respective ones of the output ports, where the conductive paths are configured as a plurality of differential pairs of conductive paths, the method comprising:
transmitting a control signal to a control signal input circuit on the communications connector that includes a reactive coupling element; electromagnetically coupling the control signal through the control signal input circuit onto a first of the differential pairs of conductive paths; outputting at least a portion of the electromagnetically coupled control signal from the communications connector via a control signal output circuit of the communications connector; detecting at a controller associated with the communications connector the electromagnetically coupled control signal that is output from the communications connector; and determining that a plug is present in the plug aperture based at least in part on detecting the electromagnetically coupled control signal that is output from the communications connector.
