Abstract

A shield for the enclosure of a data processor is made of C-shaped channel members that are located along the edges of the enclosure with the vertical surface of the channel facing outward. A channel extends horizontally from corner to corner along short edges of the enclosure, and members of a modular length are combined for longer edges. Non- modular lengths are provided for spanning the openings that are made in the raised floor for electrical connections to the processor. The channel extends vertically for slightly less than the distance between the bottom of the enclosure and the top of the openings in the raised floor. A leveling pad is located at each end of a channel member and the outwardly facing surface of the channel has an opening to admit a wrench for adjusting the pad.

Enclosure for Data Processor With Removable Electromagnetic Shield Located Between the Bottom of the Enclosure and the Raised Floor

A shield for the enclosure of a data processor is made of C-shaped channel members that are located along the edges of the enclosure with the vertical surface of the channel facing outward. A channel extends horizontally from corner to corner along short edges of the enclosure, and members of a modular length are combined for longer edges. Non- modular lengths are provided for spanning the openings that are made in the raised floor for electrical connections to the processor. The channel extends vertically for slightly less than the distance between the bottom of the enclosure and the top of the openings in the raised floor. A leveling pad is located at each end of a channel member and the outwardly facing surface of the channel has an opening to admit a wrench for adjusting the pad. The upper horizontal surface of the channel has outwardly facing L-shaped elements that engage the lower

edge of the processor frame when the channel is raised to its proper position. The upper edge also carries leaf springs that make electrical contact with the processor enclosure. Leaf springs are located at intervals along the bottom of the channel to contact the surface of the raised floor. Fig. 1 shows a floor 2 of a computer room, a channel 3 that forms the lower edge of the processor enclosure, a section of a C-shaped channel membe...
