Abstract
Abstract A first set of conductors (e.g. 25 of them) leading for example to a communications modem, is connected by way of a corresponding set of normally-closed switches to corresponding conductors of a second set, leading for example to local equipment such as a computer. At least one of the above sets of conductors is also connected to connector means into which a multi-wire (e.g. 24 wire) patching cable may be plugged. The plugging-in of the patching cable automatically opens the normally-closed switches to isolate the first and second sets of conductors from each other, as is usually desired for patching purposes. Preferably the switches are magnetically-operable reed switches, switched between their open and closed states by magnet means controlled by the plugging-in of the patching cable. Preferably the plugging-in moves the magnet means physically from a position near the switches for which the switches are operated to one of their states, to a position more remote from the switches for which the switches assume their opposite state. In a preferred embodiment the magnet means are mounted on a slidable panel, which is moved slidably by a protruding tab on the patching-cable plug when the plug is inserted, and the panel is returned to its original position by a spring when the plug is removed. Patching of many-conductor cables is thereby made possible with a simple single motion by the operator, and with reliable and relatively inexpensive apparatus.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
176 words
In connecting apparatus of the class comprising: a first plurality of separate conductors; a second plurality of separate conductors; switch means connected between said first plurality of conductors and said second plurality of conductors; a third plurality of separate conductors; quick-disconnect connector means for temporarily connecting said third plurality of conductors to said first plurality of conductors when said connector means is in a first position; and switch actuating means for actuating said switch means between its closed and open states to disconnect said first plurality of conductors from said second plurality of conductors when said connector means is in said first position and to connect said first plurality of conductors to said second plurality of conductors at other times; the improvement wherein said switch means are magnetically actuatable, and said switch actuating means comprise magnet means positioned adjacent said switch means and means responsive to placing of said connector means into said first position for controlling the effect of said magnet means to actuate said switch means from one of said states to the other.
Claim 2
Dependent Claim
