ABSTRACT:

This invention relates generally to electrically conductive carbon fiber composites having a metal electromotively coated thereon to facilitate the electrical connection of composites to another electrical component.
Extensive effort has been expended recently in investigating various ways to make reliable electrical connections to pultruded carbon composites. Inasmuch as they are solid members, they usually require a connection scheme that includes crimping, application of conductive adhesives, or driving a connection pin into them. It is highly desirable to be able to solder the solid composite to a printed circuit board.
Carbon fiber composites, sometimes referred to as distributed filament contacts, are used in electrophotographic printing machines to make electrical connections, for example to rotating elements. Heretofore, the electrical connections have been made by mechanical means rather than by soldering the pultruded carbon fibers to a printed circuit board. Pultruded carbon fibers have been used for various types of devices.
The following disclosures may be relevant to certain aspects of the present invention:

The previously-identified patents may be briefly summarized as follows:
U.S. Pat. No. 5,139,862 describes a carbon fiber brush which may be used for electrically contacting a rotating member.
U.S. Pat. No. 5,281,771 discloses a multilayer wiring board in which fibrillated portions of pultruded carbon fibers contact the conductive portions of the first and second wiring boards.
U.S. Pat. No. 5,354,607 describes pultruded carbon fibers used as a static eliminator.
U.S. Pat. No. 5,420,465 discloses electronic switches and sensors having pultruded carbon fiber contact members.
Pursuant to features of the present invention, there is provided an electrical component having one end adapted to be electrically connected to another component. The electrical component includes a support and a plurality of electrically conductive surrounded by the support. The support has an end that is adapted to contact the other component with the end having a metal electroplated thereon.
In accordance with another aspect of the present invention, there is provided a wiring assembly including a wiring board, a support, and a plurality of electrically conductive fibers. The electrically conductive fibers are surrounded by the support. The support has an end adapted to be electrically connected to the wiring board. The end of the support connected to the wiring board has a metal electroplated thereon.
