Abstract: A cable clamp particularly adapted for use with ribbon-type connectors is readily mounted on a connector end by means of a clamp anchor portion connected to a cable-supporting base having a projecting rib. Integral opposed side walls are adapted to move inwardly relative to the base and clampingly urge a cable, containing wires to be terminated in the connector, against such base over the projecting rib which extends transversely to the cable axis. Each side wall includes laterally extending ear portions for urging engaged cable portions downwardly on either side of the base rib so as to deform the cable over the rib and assure a secure cable-clamp engagement. Such engagement enables the cable and the individual wires to resist movement relative to the clamp upon the exertion of axial forces thereon, thereby functioning as an efficient strain relief preventing disruption of terminations of the wire conductors within the connector.

Each of a plurality of terminals is provided with filter sleeves which are soldered thereto. The filtered terminal assemblies are inserted into a header housing in a fixed array. At least one conductive rubber gasket on the housing interconnects the filters to a ground plane. A metal bushing can be mounted on the conductive rubber gasket to make an interconnection with mounting means, such as a bulkhead. The elastomeric ground plane engages the filters in such a manner as to apply a biasing force to the filters without creating such a high force that there would be a possibility of destroying the filters. The header housing also allows for accommodating filters of various sizes as well as for having terminal pins pass straight through without any filtering.
