Abstract
1,132,552. Variable capacitors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 March, 1967 [22 March, 1966], No. 12698/67. Heading H1M. In a variable capacitor comprising rotor plates 3 and stator plates 5 separated by plastics dielectric layers 7 mounted in a framework of moulded insulating material consisting of front and rear plates 9 and 11 connected by rods, each comprising portions 13, 15, the rotor shaft 1 is journalled in metal plate 17 to eliminate sticking due to expansion of the plastics material, and two of the frame rods serve as supports for the stator plates 5 (Fig. 1, not shown), these tubular rods having a central bore 19 through which passes a bolt 21 screwed into an aperture 23 of metal plate 17 to clamp it to the front frame plate 9. A projection 27 of a metal ring 29 secured to a flange 31 on the rotor shaft co-operates with a segment-shaped cavity in the front plate 9 to limit the rotation of the rotor shaft. A polythene washer 33 separates the flange 31 from metal plate 17 and a wavy metal ring 34 around the flange and between ring 29 and the flange serves as a sliding contact between the rotor and tongue 35. Portion 13 of a frame rod supporting the stator plates has a narrow part 41 passing through tongues 43 of the stator plates, these tongues being separated by metal spacer rings 45 which electrically connect the stator plates. The narrow part 41 fits into a wider portion 47 of axial bore 19 of portion 15 of the frame rod. Correct alignment of the rotor shaft with front plate 9 during assembly is achieved by fitting pins through aligned openings 37 and 39.
