Abstract
814,832. Potting electrical components. WAYNE KERR LABORATORIIS Ltd., and FLETCHER, K. A. Aug. 21,1957 [Aug. 29,1956], No. 26411/56. Class 87(2). [Also in Group XXXV] A potted inductive device has resilient material disposed between a magnetic core and the potting resin. As shown a winding 18 is disposed on a wound core formed from four C- shaped parts and a rubber band 20 is disposed about the periphery before potting. The winding may be of epoxy or silicone enamelled wire on a bobbin of paper and resin and the band 20 may be of natural rubber or silicone rubber. Alternatively the resilient material may be formed in situ from silicone rubber paste. Such core parts as are not covered with the resilient material may be coated with a release agent such as silicone grease, carnauba wax, cellulose varnish or polythene. The potting resin may be polyester resin, epoxy resin or a mixture of polysulphide and epoxy resins and may include a filler such as mica, glass, alumina, silica, calcium carbonate, nylon or polyurethane.
