Assignee:

Thomas & Betts International, Inc. - Sparks NV

International Classification:

H01R 1204
H05K 111

US Classification:

174262

Abstract:

An electrical interconnect comprising a non-conductive substrate having respective opposite surfaces and a plurality of apertures formed therein extending between the respective opposite surfaces, and a corresponding plurality of elastic conductive interconnect elements located within the plurality of apertures, in which each elastic conductive interconnect element extends between the respective opposite surfaces of the substrate. Each elastic conductive interconnect element is formed of a non-conductive elastic material having a quantity of conductive flakes and a quantity of conductive powder granules interspersed therein. The interconnect elements can be integrally molded in the substrate or separately formed and inserted in the substrate.

International Classification:

B32B 522

US Classification:

4283179

Abstract:

An electrically conductive elastomer for grafting to an elastic substrate is disclosed. The conductive elastomer comprises a non-conductive elastic material having a quantity of conductive flakes interspersed therein. The conductive elastomer may further comprise a quantity of conductive particles interspersed in the non-conductive elastic material. Alternatively, a quantity of conductive particles may be imbedded in an outer surface of the conductive elastomer. The conductive elastomer is typically grafted to an elastic substrate by a thermal process.

International Classification:

H05K 100

US Classification:

174254

Abstract:

Several different types of electrically conductive elastomers are disclosed along with the methods for their fabrication. In one particular embodiment, a layered composition is disclosed which comprises a substrate, a first layer, and a second layer. The substrate is formed of a non-conductive elastic material and it has an outer surface. The first layer, which is formed with a non-conductive elastic material, is grafted to the outer surface of the substrate. The second layer, which is formed with a non-conductive elastic material having a quantity of conductive flakes interspersed therein, is grafted to an outer surface of the first layer. The second layer can further be formed with a quantity of rounded or jagged conductive particles interspersed in the non-conductive elastic material such that some of the conductive particles are present along an outer surface of the second layer. Alternatively, a quantity of rounded or jagged conductive particles may be imbedded in an outer surface of the second layer.
