Abstract
This invention relates to an electrical connection and is particularly concerned with an electrical connection to conductive materials that can serve the purpose of a heating means. It has long been known that materials that are electrically conductive can generate heat. This phenomenon has spawned a considerable number of heating means for a considerable number of different purposes. Whilst electrical heaters at large are generally successful, and more than capable of meeting their intended purpose, what has proved to be difficult, is the achieving of a uniform heating effect over a relatively wide area, substantially free from hot and cold spots or areas. Sheets or webs embodying or coated with carbon particles are known, as are flexible semi-conductive materials. Even with considerable care being exercised the surface of such materials can exhibit roughness with peaks and troughs formed by carbon particles where undesirable arcing can occur. The object of the invention is to provide a means of connecting a source of electrical power to a coating or film incorporating carbon particles, an objective met by providing a coating of a nickel compound to the coating or film of carbon particles, and applying to the nickel coating a tin-copper tape coated with a silver-loaded conductive adhesive.
