1. An electrical connector shield assembly, comprising:
- a shield base having a lower wall extending from a conductor receiving end to a connector receiving end, and lateral side walls extending upwardly from the lower wall, said shield base being formed of an electrically conductive die cast composition;
a shield cover shaped to matingly fit over said side walls of the shield base to form a shielded chamber, said shield cover being formed of an electrically conductive die cast composition;
said shield base having, as an integral part thereof, a die cast central conductor alignment columns, said lateral alignment columns being located on opposite lateral sides of said central alignment column, said central and lateral alignment columns extending upwardly from the lower wall in spaced relationship from the lateral side walls and extending sufficiently above the lower wall to support the shield cover against collapse and further being located to guide at least one conductor extending from the conductor receiving end to the connector receiving end into a desired alignment with a terminal of a connector module at the connector receiving end to reduce misalignment of the terminal; and
means for securing said shield cover to said shield base;
the connector module being located in said connector receiving end of said shield base, said module havinga plurality of electrical contact elements connected to respective conductors in a cable,an electrically insulating housing containing said electrical contact elements in predetermined terminal positions,a conductive shell surrounding said insulating housing, andmeans for establishing electrically conductive and mating engagement of said conductive shell with said shield base and said shield cover; and
said lateral walls at the cable receiving end of said shield base being provided with slots and said shield cover being provided with cable clamping tab elements extending therefrom and sized to respectively fit into said slots, said cable clamping tab elements having a tapered cross-sectional shape with thicker portions being adjacent said shield cover and narrower portions being at ends of said tab elements.

Abstract
A shielded electrical computer cable connector that has high strength and resistance to crushing forces includes a shield base and a shield cover formed from die cast zinc which together form a shielded chamber. A shielded cable is received in one end of the shielded chamber and a connector module having electrical terminals is secured to the other end of the shielded chamber. The shield base has several conductor alignment columns which retain cable wiring within the chamber in alignment with the terminals in the connector module, and which also support the shield cover.
