Problems solved by technology

[0006] EMI, RFI and ESD sleeves made from coated conductor yarns like this are often effective at eliminating electrical interference, but are rather expensive to construct, especially when expensive coatings like silver are used
In addition, the conductive coating may be worn away, rendering the conductive connection between the conductive components ineffective, thereby affecting the performance of the bushing to provide optimal EMI, RFI and ESD protection

Embodiment Construction

[0030] Referring more particularly to the drawings, FIG. 1 shows a sleeve 10 constructed in accordance with the present invention constructed from yarns comprising at least some blended yarns or filaments, hereinafter simply referred to as blended yarn elements 12 . The term filament here includes monofilaments and / or multifilaments, with specific reference to the type of filament. Non-conductive monofilament and / or non-conductive multi-filament elements (hereinafter referred to as non-conductive element 14 unless otherwise specified) twisted and / or wound micron-scale continuous conductive wire filaments (hereinafter referred to as wire filaments) Filament 16) forms hybrid yarn element 12 (Figs. 5-16). For example, the diameter of each wire filament 16 is about 20-100 μm, and the wire filament provides electromagnetic interference (EMI), radio frequency interference (RFI) and / or protection from at least one of electrostatic discharge (ESD). Once enclosed, the generally seale...

Abstract

A hybrid yarn filament and sleeve constructed therefrom for protecting elongate members against at least one of EMI, RFI or ESD is provided, along with methods of constructing the hybrid yarn filament and sleeves. The hybrid yam filament has a non-conductive filament and at least one conductive wire filament overlying an outer surface of the non-conductive filament. The hybrid yarn filament is arranged in electrical communication with itself or other hybrid yarn filaments during construction of the sleeve to provide uniform shielding against EMI, RFI, and / or ESD.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 12 / 554,454, filed September 4, 2009, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention mainly relates to a sleeve for protecting elongated elements, and more particularly to a sleeve for shielding EMI / RFI / ESD yarn and its construction. Background technique [0004] Electromagnetic interference (EMI), radio frequency interference (RFI), and electrostatic discharge (ESD) are known to pose potential threats to the proper operation of electronic components due to inductive coupling between adjacent electrical conductors and electromagnetic wave propagation. Electronic systems generate electromagnetic energy due to the flow of current in a circuit. Electromagnetic energy can adversely affect the performance of surrounding electronic components, whether they are directly connected to a circuit or...
