1428698 Making electrical connections NARVA VEB 12 Oct 1973 [12 Oct 1972] 47815/73 Heading B3A [Also in Divisions H1 and H2] An electrical connection is established between a metal wire 4 and a metal member 1 by pulling the wire at an angle to the edge of the member until the wire severs. The pulling may cause the wire to snag into the edge of the member. The wire is a supply lead to the filament of a bulb and the member 1 is the screw-in cap. The bulb has a glass envelope 3 and a siliconresin based cement 2 between the cap and the envelope. The cement expands on hardening to press the wire against the cap to ensure good. electrical contact. The connecting method may be applied in the manufacture of fluorescent tubes, cathode-ray tubes, valves or cartridge fuses.
