Abstract
Abstract A one piece metal stamping forming an RF-EMI shield for an electrical connector has a central face portion and a pair of mating shell portions connected by respective bights to opposite sides of the face portion. The face portion is profiled to conform to the connector to be shielded and has an opening exposing the connector mating face. The shell portions have depending peripheral walls which overlap to enclose the rear portion of the connector and conductors extending therefrom. The subject shield is particularly suitable for electrical connectors which are overmolded with an insulative layer.
