The invention provides EMI cable shield termination apparatus. The apparatus includes (a) a cable exit panel coupled to a first electronic system and (b) one or more clamps coupled to the exit panel. The exit panel serves as an interface for one or more cables coupled to the first electronic system; the clamps provide mechanical coupling, and EMI shielding, for the cables to that interface. The exit panel couples to electrical ground such as through connection to the chassis of the first electronic system. The clamps also couple to ground through connection with the exit panel. Preferably, one end of the cables attaches to the clamps, at the interface formed by the exit panel, and the other end of the cables attach to respective ferrules coupled to a second electronics system. Beneficially, the apparatus reduces EMI effects generated from the first electronic system and coupled into the second electronic system. In preferred aspects of the invention, the first and second electronic systems are computers; and each of the clamps forms at least one aperture (&ldquo;clamp aperture&rdquo;) to affix to a cable coupled to the first electronic system. The invention facilitates configurable cable shield terminations to meet mechanical requirements of a given installation; that is, a single cable construction permits multiple optional clamp attachment locations to accommodate different separations of the attached equipment.

A control panel assembly includes a modular control panel box that is mounted to a door. The door is used to cover an opening that affords access to an internal component bay that resides within an electrical system housing. A tongue and groove joint provides a mechanism for selective positioning of the modular control panel box on the door such that the modular control panel box may be moved to a position that does not interfere with opening motion of the door that, otherwise, would occur when the modular control panel box moves rearwardly of the opening to contact an adjacent chassis.

A shielded cable assembly contains one or more hardpoints that resist damage arising from possible collapse of the shielded cable assembly under strong compressional forces that are exerted by a clamp assembly in the form of a separable block having first and second opposed members. The hardpoint contains a conduit that protects a data transfer line or cable bundle by compressing electromagnetic shielding between the conduit and the clamp assembly. Cable electromagnetic shielding may be exposed over a selected hardpoint for use as needed in a particular application.

A system for ventilating electronic equipment and suppressing the radiation of electromagnetic interference (EMI) from the electronic equipment. More particularly, the present invention relates to a ventilation port and EMI wave-guide. There is provided corrugated spring member is compressed between a first plate and a second plate so as to define a plurality of ducts, each having a depth and a cross-sectional width. The spring member is in electrical contact with the first plate and the second plate.
