Elastomeric connectors, also known by the registered trademark ZEBRA connectors,〔http://tmsearch.uspto.gov USPTO Reg. No. 1017912, ''LAYERED ELECTRICAL CONTACTS AND CONNECTORS'', Filed October 10, 1974 by Technical Wire Products Inc, Cranford, NJ, USA; first used in commerce Apr 26, 1974; renewed Sept 11, 2005; last listed owner Fuji Polymer Industries Ltd Chiyoda Nogoya-shi Aichi-ken Japan 〕 consist of alternating conductive and insulating regions in a rubber or elastomer matrix to produce overall anisotropic conductive properties. The original version consisted of alternating conductive and insulating layers of silicone rubber, cut crosswise to expose the thin layers. They provide high-density redundant electrical paths for high reliability connections. One of the first applications was connecting thin and fragile glass liquid crystal displays (LCDs) to circuit boards in electronic devices, as little current was required. Because of their flexibility, they excel in shock and anti-vibration applications. They can create a gasket-like seal for harsh environments. Conductor material possibilities include carbon, silver, and gold. The length, width and height may be specified as well as the stripe pitch. Frequently a recess with ribs is specified that captures and provides the elastomer reference surface for alignment (while allowing the lateral dimension of the elastomer to increase as it is compressed) with a deflection stop to control the final part separation, and alignment pins for substrate alignment.〔(【引用サイトリンク】url=http://www.zaxisconnector.com/elastomeric-connector-design-guide-content.shtml )〕 Elastomeric connectors are widely used, from low cost consumer products such as calculators to high reliability flight data recorders.〔(【引用サイトリンク】url=http://www.zaxisconnector.com/ )〕 They are used in two ways: # spacing of rubber conductive strips equals PWB conductor spacing, with the connector precisely aligned; # spacing of rubber conductive strips less than half the PWB conductor spacing, without precise alignment. A "matrix" version consists of short, fine, metallic wires, 300 to 2,000 per square centimeter, aligned parallel but not touching each other, embedded in a rubber sheet.〔(【引用サイトリンク】url=http://www.fujipoly.com/usa/products/zebra-elastomeric-connectors/w-series-connectors.html )〕 The wires can either protrude slightly from the top and bottom of the rubber sheet, or be curved and flush with the top and bottom planes; the latter is used for repeated assembly or inspection.〔 == Applications == # LCD and electroluminescent displays # Board-to-board connections # Chip-to-board connections # Memory cards 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Elastomeric connector」の詳細全文を読む スポンサード リンク
