An improved rack assembly is provided which includes an improved configuration for mounting multiple enclosed circuit boards. The rack assembly includes improvements in heat sinking power supplies incorporated within the assembly, relative adjustability of various elements of the rack after assembly, and ventilation of the rack during operation in an efficient manner.

Apparatus for rack mounting multiple circuit boards

An improved plate for mounting a plurality of receptacles on an electronics device, particularly a data communications peripheral, is disclosed. The plate is designed to be secured to an electronic subassembly which may be dropped into a portion of an enclosure and the plate placed proximate to a large opening in the enclosure. In order to compensate for mechanical tolerances on the fit of the plate within the enclosure, since it is attached to the subassembly, free edges of the plate which may act as an elongated antenna for emitting radio frequency interference are broken up into fingers of predetermined length. This attenuates the radiation from such edge. Additionally, the fingers are bent down to contact an electrically grounded portion of the enclosure to provide further RFI suppression.

A cable management system for directing cables connected to the back of an equipment enclosure of the type containing a computer peripheral device or other electronics apparatus to enter and exit the equipment enclosure at a selected one of a plurality of predetermined orientations. A bottom cover of the equipment enclosure is provided with a recessed portion including a vertical wall upon which is mounted receptacles for receiving cable terminations. Upper stanchion portions at the rear of the recessed portion together with a hinged plate or with lower stanchion portions contacting the upper stanchion portions from the bottom form rear legs for the equipment enclosure. The rear legs and the vertical wall of the recessed portion confine cable entry and exit positions to particular angular segments corresponding to the sides and rear of the equipment enclosure. Injection molded latches each including an elongated finger and a retaining tab are included within the upper and lower stanchion portions for connecting them together.

A separately formed slanted front panel bezel manufactured using injection molding techniques. The interior slanted surface has a plurality of positioning tabs extending perpendicular thereto. An arch shaped screw receptacle extends above the surface, the geometry which allows the mold for same to be withdrawn in a conventional fashion. When the bezel is used in final assembly, a self-tapping screw bites a semi-circular section of the arch shaped protrusion.

An improved standoff for use in assembly of an electronics device includes a generally cylindrical body with a bore hole through the longitudinal axis. A plurality of reinforcing fin-shaped members disposed radially about the outer surface provide additional rigidity to the structure as well as providing surfaces at each end of the standoff upon which circuit boards may rest. A plurality of clips may be moved under compression and passed through holes on a circuit board. Once they have passed through, they will elastically return to their normal position thus loosely, but securely, holding the circuit boards together. This allows the standoffs to hold the circuit boards together, without the use of additional nuts and bolts and conventional spacers, and also allows the passing of final assembly screws through the longitudinally bore of the spacer. An electrically conductive stamped metal spring clip is provided over a mounting post and serves the dual function of providing electrical contact between grounded conductors on a circuit board and the equipment enclosure, as well as providing a spring to compensate for mechanical tolerances and to assure the application of sufficient stress to an assembly screw to maintain the apparatus in a dependable assembly state irrespective of subsequent stress relaxation in any plastic components.

Standoff and grounding clip assembly

An enclosed circuit board assembly is provided which includes two mating enclosure members mounted to a circuit board and to each other, which combine to isolate the circuit board from contact with stray wires, human fingers, other undesirable foreign objects. The assembly is sufficiently ventilated to allow effective cooling of the circuit board by natural convection and/or forced convection, and includes a plurality of locking fingers which attach to the circuit board. A plurality of pry holes are provided to provide an effective means of removing the assembly when mounted between similar assemblies.
