Abstract
A multiconductor shielded connector is disclosed in which a flexible, compressible double bushing is used between the connector half shells and the multiconductor cable. The double bushing comprises an outer bushing dimensioned to grasp the outer jacket of the cable at the exiting end of the connector. A concentric, longitudinally offset inner bushing is inserted under the shielding (braid or foil) and mates with ridges on the inner surface of the half shells to form a tight, continuous radiation seal. The inner and outer bushings are connected together with a fine web which maintains concentricity and axial displacement of the bushings before and during assembly, but which does not interfere with the operation of the connector after assembly. The outer bushing may have a sleeve extending outside of the half shells to prevent sharp bends at the connector exit. A single bushing can be used which defines a serpentine cable path when it is desired to use the same half shells with non-shielded cable. In that case, the bushing merely provides strain relief. Both the double bushing and the single bushing can be supplied in graduated thicknesses to permit a single pair of connector half shells to accommodate a large variety of cable diameters.
