Controlled-impedance cable termination for cables having conductive foil shields

A termination assembly comprising:

• (a) a controlled impedance cable having one or more signal conductors, a dielectric surrounding the signal conductor, and a ground return composed only of a foil shield surrounding the dielectric;
• (b) a ferrule for each signal conductor, the ferrule composed of a rigid material, the ferrule having an axial through bore extending from a line opening to a face opening in a ferrule face, the bore receiving and securing the signal conductor with the dielectric and the foil shield, wherein the foil shield and the dielectric are flush with the ferrule face to form a planar mating surface with the signal conductor protruding from the ferrule face;
• (c) a boss composed of a rigid material and that has features for capturing the ferrule such that the ferrule face is aligned with a connector opening in the boss;
• and
• a rigid cover attached to the boss.

A method for terminating a controlled impedance cable having one or more signal conductors, a dielectric surrounding each signal conductor, and a ground return composed only of a foil shield surrounding the dielectric, the method comprising the steps of:

• (a) assembling a cable subassembly by at least stripping back the foil shield;
• (b) providing an electrically conductive housing having a strain relief, a junction space with a neck and a throat, and a signal run extending from the throat to a projection face of a cylindrical projection extending from an edge of the housing;
• and
• (c) installing the cable subassembly into the housing such that the cable enters via the strain relief, the foil shield is compressed in the neck, and each signal conductor with the dielectric extends through the throat into the signal run with the signal conductor protruding from the projection face.
