The present invention relates to an electronic signal switching module with connectors on a first side for connecting with a variety of devices and sources and with jacks for receiving patch cords on a second side. The switching modules include two position switches in the circuitry connecting the jacks with the connectors which allow the module to be configured as a straight-through patching module, a fully normal module with paired jacks or a half normal module with paired jacks. One alternative of the invention utilizes card edge connectors on the first side. Another aspect of the invention involves a chassis for holding a plurality of switching modules adjacent to and electronically connected with a plurality of connecting modules. The switching modules may also include designation lenses adjacent to the jacks for holding indicia.

Electronic signal transmission and switching jack

The present disclosure relates to high density patching system. The system includes a card housing having a front end positioned opposite from a rear end. The card housing includes top and bottom walls extending between the front and rear ends. The top and bottom walls define opposing sets of top and bottom slots. The patching system also includes a plurality of patch cords including patch plugs each having a width W and a height H . The patching system further includes a plurality of jack access cards adapted to be mounted in the card housing, and a rear interface module positioned at the rear end of the card housing. The jack access cards include circuit boards having top and bottom edges adapted to fit within the sets of top and bottom slots defined by the card housing. The jack access cards also include a plurality of card edge contacts positioned at a rear of each circuit board. The jack access cards further include front interface pieces having heights H that are greater than two times the height H , and widths W that are each less than two times the width W . The front interface pieces each define upper and lower patch plug ports that are vertically spaced along the height H of each front interface piece. The upper and lower patch plug ports are sized and shaped to receive only a single one of the patch plugs at a time. The rear interface module includes a single row of card edge connectors adapted for providing electrical connections with the card edge contacts of the jack access cards. The rear interface module also includes an array of rear connectors including upper and lower rows of rear connectors. The array of rear connectors is electrically connected to the card edge connectors by a flexible circuit board. The rear interface module also includes a frame that spaces the card edge connectors from the rear connectors. The frame includes a rear wall defining upper and lower rows of openings that respectively receive the upper and lower rows of rear connectors.
