Abstract

1,108,903. Plugboards. AMP Inc. 6 July, 1966 [31 July, 1965], No. 32891/65. Heading H2E. A plugboard comprises parallel insulating laminµ (Fig. 2) carrying printed conductors 9, 10 (shown on a lamina turned through 90 degrees from its assembled position) and separated by spacing means, such as spacers 4, which with the laminae define apertures to receive plugs 23 having resilient contacts 29 which interconnect the conductors 9, 10 at respective apertures. Alternatively (Fig. 6) the spacing means may consist of further printed circuit laminµ arranged orthogonal to the first set and in egg-crate fashion. As shown in Fig. 2, the spacers 4 are apertured at 8 to receive tie-bars for securing the assembly together and to mounting brackets, while the laminae 3 are apertured at 12 to receive wires which inter-connect the corresponding conductors 9 of the laminµ in cross-bar or other configuration. The laminµ 3 are slotted at their ends 13 to receive connectors which make contact with the printed conductors 11 associated with the conductors 10. The contacts 29 of each plug 23 extend into a cavity 26 and are interconnected by an electric component or shorting strip, or are connected to flying leads. The plugs 23 and plug apertures may be chamfered as at 24<SP>1</SP>, 24 for polarization. The laminµ 3 may be the edges of printed circuit boards (38) (Fig. 5, not shown) carrying circuitry and electric components and further interconnected by a perpendicularly arranged printed circuit board (39). A transparent cover may be snap-fitted over the plug board. In the arrangement shown in Fig. 6, both sides of the sets 40, 41 of the laminae carry printed conductors 46, 48 arranged to be selectively interconnected by spring contacts 51 on each side of a plug 50 which extend into a componentreceiving cavity 52 as before.
