1473529 Terminal blocks; terminals WESTERN ELECTRIC CO Inc 4 Sept 1974 [10 Sept 1973] 38580/74 Heading H2E An insulating terminal block (101, Fig. 1, not shown) has terminals 102 seated in apertures (110) and has attached to it wire forming strips (103), 104 having tapered wire insertion slots 305, whose width narrows to slightly less than the wire to be inserted, leading into fanning apertures 306 partially closed by lips 307, 308 to restrain any wire in the apertures 306 and thus to prevent wire breakages due to bending. The terminals 102 are of phosphor bronze stampings and comprise two sets of insulation piercing jaws 203 which may be spot-welded together, one set being integral with a wire wrapping post 202. The strip and block assembly may be used in the distribution frame of a telephone office and is located on a frame (Fig. 7, not shown) by grooves (402) in one strip and posts 501-503 in the other. The block (101) and strips (103), 104 may be injection moulded polycarbonate thermoplastic resin.
