Electrical connector shield with castellations

摘要

A connector backshell assembly has a first annular member which can be a metal-plated plastic cylinder 20 with castellations 21 at its rear end through the screening sleeves 7 of cables 3 are threaded. A second annular member which can be a cap 30 embraces the castellations 21 and has internal projections 32 that project into recesses 22 between the castellations. A third annular member which can be a coupling nut 50 extends around the cylinder 20 and bears against the rear end of the cap 30 so that the cap is clamped onto the cylinder when the nut is screwed onto the rear of a connector. This clamps the screens 7 between projections 32 in the cap 30 and the recesses 22 in the cylinder 20 so as to make electrical connection with the screens 7.
