Abstract: A card cage formed of mating, identical halves provides parallel slots for circuit boards carrying snap-on retainer clips with integral pawl-like clasps which lock over ridges on the exterior of the card cage. The clip is released from the cage by squeezing the clasps with one hand before withdrawing the circuit board. Slotted side brackets capture mating ribs on the card cage halves to assemble and mount the card cge to a wiring clost panel.

Abstract: A mounting for the electronic components of computer system's functional control unit comprises a housing for supporting a display unit and for enclosing an electronics chassis comprising electronics to control access to a variety of peripheral units. The electronics chassis is removably mounted within the housing on slide rails so as to be removed, serviced or replaced without having to lift the terminal off the housing of the functional control unit. The mounting thus simplifies the installation and maintenance procedures for computer systems.

Abstract: A modular faceplate system having four levels of modularity includes a standard faceplate, a plurality of secondary support members, and a plurality of modules. The faceplate may be secured to a variety of support structures such as an outlet box, a modular box and a wall box. The faceplate has an elongated opening formed therein for the secondary support members. The secondary support members support the various different modules in various configurations. The modules can support a variety of electrical devices including plugs and electrical connectors. The faceplate, secondary support members and modules all include snap-type fastening means such that a desired faceplate configuration can be assembled from the component parts without the use of hardware.
