Abstract: A connector having a core with a flexible circuit supported therearound, the flexible circuit having an array of signal conduction tracings on the first, exterior, surface thereof, the connector being characterized in that the second, interior, surface of the flexible circuit has an impedance control arrangement comprising at least one ground tracing connectable to ground potential and arranged with respect to the signal conduction tracings such that the impedance of the signal conduction tracings matches the impedance of conduction paths to be interconnected.

Abstract: An electrical wiring device comprising an insulated flat cable having a plurality of parallel electrical conductors disposed in a plane and encased in a flexible insulation with at least one connector assembly permanently attached for plug-in service is provided. Also provided is a method of making the device in which insulation-piercing interconnecting elements are passed through the insulation, have a tight bight of conductor formed outside the insulation and are permanently bonded to tines in each interconnecting element, and the associated parts are enclosed in a dielectric housing.

Abstract: A vertical header with an integral housing surrounding a block through which straight pins extend. The pins project beyond one face of the housing that is adapted for mounting against a circuit board. Above the block, the housing and pins receive an electrical connector. At each end of the housing block, there is a latch member that extends upwardly from the block for engagement with a connector fitted into the housing.
