Abstract: 1387587 Making connectors for printed circuit boards PLESSEY CO Ltd 4 July 1972 [22 July 1971 7 Aug 1971 20 Nov 1971 15 Dec 1971] 34410/71 37223/71 54007/71 and 58170/71 Heading B3A [Also in Divisions H1 and H2] An electrical interconnector, for connecting pads on printed circuit boards and comprising a number of separate conductors retained in a block of insulating material and running between opposite faces of the block is made by convoluting a continuous length wire into a form having a plurality of substantially parallel portions, enclosing the wire in the insulating material and cutting through the block produced on parallel planes transverse to the parallel wire portions. The interconnector may be made by winding a wire 8, Fig. 5, around posts 6 in a trough 7 and then covering the wire with liquid rubber. After the rubber has set another wire is wound around the posts and more rubber poured in. The process is repeated until the trough is full. The layers are then bound together by heat to form a block which is removed from the trough 7 and trimmed along the lines 10 and 11. In another method of making the interconnector, the layers are built up by winding wire helices on a cylindrical mandrel and the interconnector produced by taking a radial slice. In another method, a single layer is formed on a cylindrical mandrel, opened out and sliced into portions by cuts parallel with the conductors. The portions are stacked upon each other and the interconnector produced by slicing perpendicular to the conductors. The interconnector may be used to make connections to and between printed circuit boards (see Division H1).

[Also in Division D1] In apparatus for making wire netting having intersecting and welded wires, a transverse wire feed device is rotatable in a plane transverse to the plane in which the netting is formed about the axis of a hollow shaft through which a wire or wires are fed, rotatable transverse wire guide means are provided on opposed longitudinal sides of the netting to advance the transverse wire layer and a pair of welding rollers is provided. The transverse wire feeding means comprises a hollow shaft 11, Fig. 1, through which a single wire 6 is fed rotated by a pulley 10 and carrying a wire laying arm 14. An extending portion 14a of the arm 14 carries a shaft 17 for toothed wheels 15, 16 meshing with wheels 18, 19, the former 18 being fixed and the latter 19 carrying bearings for rotation of the shaft 11 therein. The wheel 19 carries a pair of coils 24, 25 rotatable by chains 31, 32 from the shaft 11 and extending parallel to and beyond the limits of the longitudinal wires 3 of the netting. On rotation of the shaft 11 the wire 6 passes through the shaft, is guided over rollers 33-38, on the arm 14 to be wound round the coils 24, 25 which advance the wire along with the longitudinal wires 3 fed over the lower roller 4 of the pair of roller electrodes. Marginal wires 47, 48 are fed from spools 45, 46. The netting passes through the electrode rollers which are formed of separated discs, the marginal wires being welded by separate rollers beyond the main rollers. In a modified apparatus a star-shaped plate 14b, Fig. 3, is provided on the shaft 11 instead of the arm 14 and at the other end of the shaft 11 a plate 69 carrying a number of spools of wire is arranged. The wires are fed through the shaft and supplied over rollers and through guide holes in the plate 14b to be wound around the coils 24a, 25a so that rotation of the plate 14b produces a netting formed by intersecting diagonal wires.
