Abstract
Abstract An EMI shielded connector is provided having an exterior receptacle shell, plug housing and coupling member constructed of plastic. Metallic sleeves line the shell and housing interiors and enclose insert assemblies. The sleeves are releasably engaged at a joint connection to provided electrical continuity through the connector for EMI protection. A junction means may be used to enhance electrical communication at the joint connection and a sealing member is used for environmental protection of the connector interior parts.
