Abstract

1,240,787. Making cartridge fuses. LUCIEN FERRAZ & CIE. 15 Dec., 1969 [17 Dec., 1968], No. 60978/69. Heading B3A. [Also in Division H2] A method of making cartridge fuses comprises forming an end of a tubular body 1 with angularly spaced notches defining teeth 1c, shaping an end cap 3 with teeth 3a corresponding to these teeth 1c so that it may assume a first position in which the teeth 3a are engaged in the notches and a second position in which the teeth 3a abut the teeth 1c, welding fuse elements 6 to the cap 3, engaging this cap in the body 1 in the first position so that the elements 6 project beyond the opposite end of the body, welding the elements 6 to a non-toothed end cap 2, bringing the cap 3 to the second position with the cap 2 abutting the opposite end of the body and fixing the caps 2, 3 in position. The caps are held in place by clips 8, 9, which engage in peripheral grooves 1a, 1b. The body is filled with sand 7 through an aperture 3c in the cap 3 and a corresponding aperture in the clip 9, the apertures then being sealed. The terminal blades 4, 5 may be notched to accommodate clips (10) on which insulated handles are attached for removing the fuse from its support, Fig. 6 (not shown). An indicator head (11) of plastics material may be secured in a depression (9b) in the clip 9 by a retaining wire (12) which melts when the fuse has operated thereby releasing the head, Fig. 7 (not shown).
