Abstract

994,031. Making electrical conductor assemblies. STANDARD TELEPHONES & CABLES Ltd. Aug. 30, 1963 [Aug. 31, 1962], No. 33532/62. Addition to 993,983. Heading B3A. [Also in Division H1.] In an electrical conductor assembly, one or more layers of metal wire or strip, formed to a predetermined standard pattern, is/are embedded in insulating material to form an insulating member having one or more layers of conductive tags projecting from one or both of its longer edges; and holes are drilled, manually or by a programme controlled drilling machine, into the insulating material and through at least one metal layer to separate each such layer into electrically separate parts to provide a desired pattern. In Fig. 2, two conductor forms 7, 8, which may be grids formed by welding, or punched plain strips, are encapsulated in an insulating strip, holes being drilled where shown to provide a desired pattern of interconnections. Interconnection between separate conductive layers is provided in the embodiment shown in Figs. 3, 4, in which the tag portions on two conductive forms are connected and a border, which may be drilled as required, joins the tags on each side. Circular forms may be used; Fig. 8 shows an annulus of brass or copper in which holes 31, 32 have been punched. The inner and outer regions 34, 33 are removed and a plurality of mutually insulated forms are encapsulated in a grooved and castellated ring of insulating material, or, by moulding or casting, in a plastics material. Fig. 12 shows one of two such conductor assemblies, between which are connected modular units which may be of the type described in Specification 931,570, and may be of keystone configuration, as at 46. Semi-circular and other arcuate forms may also be employed; the semi-circular layout of a transistorized bi-stable circuit is depicted in Fig. 7 (not shown). Where blind holes are drilled to sever one of a plurality of conductive layers, the hole may be filled with insulation. Tags not used electrically may be retained for use as mechanical anchors. Complete assemblies of conductors and modules may be totally encapsulated.
