Abstract
Abstract A radio frequency and electromagnetic shield for an electrical connector comprising a spring band which is interposed between the mating halves of the connector. The band is formed from a sheet of resilient metal which is lanced to provide alternating slits which open at opposite edges of the band. The band is expanded over the male half of the connector so that the slits open, providing therebetween spiraled spring arms. When the mating halves are connected, the band is radially compressed causing the spring arms to untwist thereby closing the slots in the band.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
163 words
In an electrical connector comprising plug and receptacle connector members having contacts therein which engage upon axial mating of said connector members along a center axis thereof, said plug connector member having a barrel slidable into the shell of said receptacle connector member, and shielding means for said contacts disposed between the outer surface of said barrel and the inner surface of said shell, said shielding means comprising an annular band formed of resilient metal being convexly curved in the longitudinal direction, said band having alternating slots therein opening at the opposite edges thereof, the improvement which comprises: at least one side of each said slot being skewed relative to said axis and being higher than the other side of the slot; and said band having a sufficient radial height and interference fit with respect to said shell whereby upon mating of said plug and receptacle connector members, said shell will radially compress said band to cause said slots to substantially completely close.
