Universal/Portable Cable Support and EMI Reduction Bar

摘要

A Universal/Portable Cable Support and EMI Reduction Bar which to attenuate electromagnetic interference on the input/output cables of the electronics rack passing therethrough before the cables exit the rack. The bar works for cables exiting any part of the rack. The design involves an introduction of a grounding bar that can serve as EMI suppression (detuning frame resonance and reducing cable emissions) as well as cable support/retention functions. The bar provides a stable Ethernet cable support and EMI (Electromagnetic Interference) suppression structure which reduces EMI emission on the cable as well as eliminates the extra connection needed when using a separate RF (Radio Frequency) choke. A device, system and method are provided.

主权项

1) A device for cable support and electromagnetic interference (EMI) reduction in an electronics rack, the device comprising:
a cable support bar having at least one opening for at least one cable of the electronics rack to pass therethrough, the cable support bar having a first end and a second end and formed by joining a top section half and a bottom section half, the rack having a first side wall and a second side wall; the top section half of the bar having at least one top channel and the bottom section half of the bar having at least one bottom channel, wherein ferrite inductor portions are dispersed within and around the at least one top channel and the at least one bottom channel; a first attachment mechanism to attach and ground the first end of the bar to the first side of the rack; and a second attachment mechanism to attach and ground the second end of the bar to the second side of the rack; wherein: the top and bottom section halves of the bar are disposed so that when the top section is attached to the bottom section the top section and bottom section thereby form an attached structure with the channels aligned to create the opening through which the at least one cable may pass; and the attached structure applies force to the ferrite inductor portions to ensure that the top ferrite inductor portion and the bottom ferrite inductor portion make physical contact thereby forming an electromagnetic inductor around a cable passing through the opening.
