Abstract: Method as well as apparatus makes and breaks electrical connections between at least one electrical cable connector and an electronics module that has at least one corresponding panel connector. A rack receives and holds the module. A cable-connector holder, formed in the rack, receives and holds the cable connector(s) in positions aligned with the panel connector(s) when the electronics module is held in the rack. Each cable-connector holder easily and quickly engages, or disengages from, a corresponding cable connector. The rack itself provides only a mechanical intermediary, not an electrical intermediary, between the panel connectors and cable connectors. Preferably there are numerous cable connectors, with corresponding cable-connector holders and panel connectors. In this case the rack includes a device for quickly and easily disengaging the electronics module from the rack, and all the cable connectors from panel connectors, essentially simultaneously.

Abstract: Electrical connections between a cable connector and an electronics module—that has a corresponding panel connector—are made/broken quickly and easily with a light, low-bulk half-shell that is an exclusively mechanical, nonelectrical intermediary from connector to module. A rack receives and holds the module, and a connector holder, formed in the rack, receives and holds the cable and panel connectors aligned. A cam is associated with the rack or module, and a cam-follower with the other—preferably in duplicate opposed sets. A single, one-hand-actuated lever on the rack or module operates the cam or follower to bodily shift module vs. rack and engage/disengage the connectors. Preferences: each holder easily and quickly engages/disengages from a corresponding cable connector. Typically a module weighs at least several pounds. The cam has a concave arcuate segment to draw the module in and seat the connectors, and a convex arcuate segment to eject the module and unseat them.

Abstract: The system provides electricity to operate any of a multiplicity of device and most typically receives power from a source and passes power to any of the devices. The system also accepts electronic-device identification information for any particular one of such devices. The system also has one or more programmed digital electronic microprocessors that use the identification information to select power parameters--for passage of power from the source to the powered device. The system activates its own power-passing capability to apply power to each device according to the power parameters selected by the microprocessor.
