Abstract

In a computer system many machines and control units are combined to complete an installation. These units are connected by cables that in most instances are connected to the circuitry of the unit by connector plugs. Often these plugs are located on the sides or back of the unit frame, even within the machine itself. They are, therefore, awkward to reach when it is desired to temporarily disconnect the unit from the system. This cable plug contains devices for switching that permit the removal of part or all of the circuitry of the machine from the system without disconnecting the cable.

Switchable Cable Connector

In a computer system many machines and control units are combined to complete an installation. These units are connected by cables that in most instances are connected to the circuitry of the unit by connector plugs. Often these plugs are located on the sides or back of the unit frame, even within the machine itself. They are, therefore, awkward to reach when it is desired to temporarily disconnect the unit from the system. This cable plug contains devices for switching that permit the removal of part or all of the circuitry of the machine from the system without disconnecting the cable.

Normally, connectors 10 and 12 are plugged together. If a given computer system requires a connect-disconnect ability between certain machine units, the connectors 10 and 12 can be separated and reconnected with switching unit 11 in series to provide the switching ability. Such is with little or no alterations to the machine unit.

The device comprises one-half of a normal multi-position connector 10, switching unit 11, and one-half of a second connector 12. Connector 10 has male block 14 and female block 15. Plug 12 is formed of two similar blocks 16 and 17. Block 17 is provided with cover 18 enclosing ends of cable 19.

Switching unit 11 has reed switches 20. Their terminals 21 are secured by wires soldered to the connectors 22 in the blocks 15 and 16. Switches 20 are stacked in groups with their terminals held in end plates 23 of insulating material an...
