Abstract

1444776 Making electrical contact elements; extruding G RAU 17 Oct 1973 [17 Oct 1972] 48450/73 Headings B3A and B3P [Also in Division H1] An electrical contact element is made of fibre impregnated material and at least its contact surface is shaped by plastic deformation. The fibre reinforced material may form the whole element or just the contact surface, Fig. 2 (not shown). The fibres extend unidirectionally and are substantially normal to the contact surface. The fibres may be all of the same material, e.g. a base metal, or of different materials. They are provided in a matrix material, e.g. silver. Suitable material combinations are silver/nickel, copper/tungsten and silver/titanium. The element is produced by upsetting a cut-off length of fibre impregnated wire. In the second embodiment the contact surface is cold welded to the stem which may be copper.
