Electrical component substrate with cavities for anchoring lead wires therein

Claim 1

A HIGH-HEAT RESISTANT SUBSTRATE OF CERAMIC DIELECTRIC MATERIAL FOR AN ELECTRICAL COMPONENT ADAPTED TO SUPPORT A PLURALITY OF ELECTRICAL DEVICES COMPRISING A FLAT TOP SURFACE FOR SUPPORTING THE ELECTRICAL DEVICES, A FLAT BOTTOM SURFACE PARALLEL TO THE TOP SURFACE, A PAIR OF END SURFACES IN SPACED RELATIONSHIP, A REAR SURFACE AND A FRONT SURFACE, THE DISTANCE BETWEEN THE TOP SURFACE AND THE BOTTOM SURFACE BEING SUBSTANTIALLY LESS THAN THE DISTANCE BETWEEN THE REAR SURFACE AND THE FRONT SURFACE, A PLURALITY OF SPACED RECESSES ARRANGED ALONG THE FRONT SURFACE OF THE SUBSTRATE, EACH OF THE RECESSES BEING PROVIDED WITH AN INNER WALL SUBSTANTIALLY PARALLEL TO THE FRONT SURFACE OF THE SUBSTRATE, AND A CAVITY COMMUNICATING WITH THE INNER WALL OF EACH OF THE RECESSES FOR RECEIVING A LEAD WIRE, THE CAVITY BEING OF A SIZE INSUFFICIENT TO RECEIVE FREELY AN END PORTION OF THE LEAD WIRE, THE END PORTION BEING FORCED INTO THE CAVITY TO DEFORM THE LEAD WIRE AND FIXEDLY SECURE THE LEAD WIRE DIRECTLY TO THE SUBSTRATE.
