Abstract

1,021,926. Sealing fuse boxes and lampholders. BELLING & LEE Ltd. May 1, 1964, No. 18113/64. Headings H2E and H2G. An electrical lead-through connection for a fuseholder or lampholder comprises a fluid-tight seal consisting of a silicone rubber or neoprene bung 7 (Fig. 1) which surrounds one or more conducting members 5 and 6 between the closed ends of two insulating sleeves 1 and 8 and which is held in compression by a spring 11. A metal washer 13 having teeth 16, 17; 18, 19; 20, 21 (Fig. 2) on its periphery is forced into the sleeve 1 to compress the spring 11 after which, under pressure from the spring, the teeth bite into the walls of the sleeve 1 to retain the spring 11 under compression. The embodiment in Fig. 1 shows a fuseholder arranged to hold a cartridge fuse between a contact limb 10 of conducting member 6 and a spring 28 which is connected to contact fingers 27 of conducting member 5. Solder tag eyelets may be attached to the ends of the conductors 5 and 6 outside the holder. In an alternative embodiment a sealed lampholder, consisting of a transparent lid screwed on to the open end of body 1, houses a lamp in sleeve 8.
