A connector assembly providing uninterrupted protection against electromagnetic interference includes a receptacle having a recess in which a first contact assembly is positioned, and a plug having a mating portion which fits into the recess. The mating portion contains a second recess in which a second contact assembly is positioned to mate with the first contact assembly as it projects into the second recess from the first recess. Pivotally mounted doors within the first and second recesses protect the contact assemblies from radiation when unmated, and a spring contact between the mating portion of the plug and the walls of the first recess protect the contact assemblies from radiation during transition between unmated and mated conditions.

EMI protected connector assembly

An electrical connector member including a hollow housing member with an internal restricted passageway, an adjacent outer radial shoulder and a reference surface axially spaced from the shoulder oppositely to the passageway; and an insert member snugly retained against axial movement in first and opposite axial directions by said shoulder and surface, the insert member including a restraining surface in abutment with said shoulder, the restraining surface being shaped by plastic deformation of the weakened peripheral surface portion on the insert member by the wall of the restricted passageway during the final stages of the positioning of the insert member. The insert member before deformation includes the weakened peripheral surface portion formed by a plurality of axially extending knurls, and an adjacent protective collar which protects the weakened portion from deformation until the collar has passed through the restricted passageway and the insert member is in the final stage of positioning.
