摘要:
Spring apparatus is provided which includes coil springs having intermediate and end coils suitable for interconnection in order to form a continuous spring which maintains a constant load-deflection characteristic over all intermediate coils unaffected by the joint end coils. This configuration therefore finds particular utility in providing bias without compromise of sealing, electromagnetic shielding and/or conductivity.

An electromagnetic shielding spring gasket assembly includes a coil spring for blocking the propagation of electromagnetic waves therepast. The coil spring includes a plurality of coils having a major and a minor axis and canted along a center line defined by an intersection of the major and minor axes and may be interconnected in a manner forming a radial garter-type canted-coil spring. A back angle of each coil defines the disposition of a trailing portion of each coil with respect to a line normal to the center line which determines a radial load-deflection characteristic of the canted-coil spring assembly. A front angle of each coil defines the disposition of a leading portion of each coil with respect to the normal line. The plurality of coils are noninvasively supported in an orientation for controlling the blocking of electromagnetic waves, for radial loading of the radial garter-type canted-coil spring and for controlling the resilient characteristics of the radial garter-type canted-coil spring.

L'invention concerne un joint d'étanchéité amélioré destiné à protéger un équipement électronique, et notamment destiné à des enceintes adaptées pour recevoir de l'équipement électronique. Ledit joint d'étanchéité a la forme d'un composant à deux couches solidaires, c'est-à-dire une couche de support (16) et une couche de couverture (18), le support étant résistant et présentant d'excellentes propriétés physiques, et la couche de couverture étant remplie de métal et présentant d'excellentes propriétés d'atténuation d'énergie électrique.
摘要:
Zwischen den Flächen zweier aufeinanderliegender Teile eines Gehäuses für elektronische Geräte wird in einer Nut in einem der Gehäuseteile eine Dichtungsschnur, die mindestens an der Oberfläche aus einem Drahtgewirk besteht, eingelegt, um eine hochfrequenzmäßige Dichtung zu erreichen. Diese Dichtungsschnur wird von einem längeren Stück auf Maß abgeschnitten, und an den Schnittstellen können sich lose Drahtteile des Gewirks bilden, die nach dem Einlegen der Dichtungsschnur in das Gehäuse mit der elektronischen Schaltung fallen und dort Kurzschlüsse auslösen können. Um dies zu verhindern, werden die Enden der Dichtungsschnur in Sacklöcher gesteckt, die in der Nut angebracht sind. Dabei kann die Nut im Bereich der Sacklöcher verbreitert sein, so daß die beiden Enden der Dichtungsschnur auf einem kurzen Stück parallel verlaufen. Zum besseren Fixieren der Enden und zum zuverlässigen Verhindern des Herausfallens von Drahtenden können die Sacklöcher mit Klebstoff versehen sein.
摘要:
A conductive electromagnetic interference (EMI) shielding gasket having a compressible non-conductive core enwrapped with a conductive sheath. The sheath is a laminate formed by laminating a conductive metal foil at least 0.2 mils thick to a flexible non-conductive substrate, preferably a non porous polyester film.

An electromagnetic shielding gasket is provided, which is capable of reducing the amount of projection from the inner surface of a first opposing wall having gasket holding holes and is less likely to come off through the gasket holding holes in the direction from the inner surface side toward the outer surface side of the first opposing wall. A communication device as an electronic device has a device body having a plural number of sub-casings and electromagnetic shielding gaskets 1. A first opposing wall 102a disposed on the sub-casing of the device body includes a plural number of gasket holding holes 104 and gasket guiding holes. The electromagnetic shielding gasket 1 has a gasket body 2 and a plural number of fitting parts 4 and come-off stopping parts 3. The fitting parts 4 are guided in the gasket guiding holes and then fitted in the gasket holding holes. The come-off stopping parts 3 are formed not to come off through the gasket holding holes 104 in the direction from the inner surface side to the outer surface side of the front wall 102a even if they deform under external forces.

Tor mit einer zumindest teilweise umlaufenden Dichtungseinrichtung, mit einer Halteleiste aus Metall, innerhalb welcher die Dichtung angeordnet ist, wobei die Dichtung pneumatisch aktivierbar ist, mit einer oberhalb der Dichtung befindlichen verstellbaren Platte, die durch Führungseinrichtungen gegenüber der Halteleiste verstellbar geführt ist, mit einem elektrisch leitenden Gewebestreifen, der die Halteleiste elektrisch mit der Platte verbindet, und mit auf der Platte angeordneten Kontaktfedern, die elektrisch leitfähig sind und in Anlage zur Anschlagleiste des gebäudeseitig vorgesehenen Einbaurahmens verbringbar sind.
摘要:
A shielding strip (100) according to one aspect of the invention includes a generally longitudinally extending region and at least one generally transversely extending slot (108) along the generally longitudinally extending region. The slot (108) has at least one enlarged portion (112) having a larger cross section than the slot (108). The enlarged portion(s) (112) may be, for example, at an end portion of the slot (108) and/or at about a predetermined area of high stress concentration. Other aspects of the invention include methods of making shielding strips (100).
摘要:
A method and apparatus for grounding a chamber isolation valve (101) are provided. Generally, the method makes use of an electrically conductive elastomeric member or members (107a) to effectively ground a chamber isolation valve and/or isolation valve door (107) while avoiding metal-to-metal contact between moving parts in the processing system. In one embodiment, the elastomeric member is attached to and in electrical communication with the door (107) of the chamber isolation valve. The elastomeric member is brought into contact with a grounded component of the plasma processing system when the door is in the closed position. In another embodiment, the conductive elastomeric member is attached to a bracing member (109) of the isolation valve and is brought into contact with a grounded component of the plasma processing system when the bracing member is deployed to hold the isolation valve door in place during substrate processing. Other configurations are also provided.
