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.

Environmentally protected EMI shielded connector

A threat field sensor has a hollow metal enclosure with imperforate side walls except for a single aperture that is small as compared with the wavelength of interfering electromagnetic energy. A coaxial conductor is located in the enclosure cavity and has separate sets of leads interconnected to each conductor end. Electric signals induced in the coaxial conductor and present at the conductor ends by the external electromagnetic fields passing through the enclosure aperture are converted to two corresponding light signals. The light signals are transmitted to remotely located processing apparatus by an optical fiber link where the light signals are converted once again to electric signal counterparts. Summing and differencing these electric signals provides two final signals representative of the electric and magnetic field, respectively. The electric field being normal to the coaxial conductor is uniquely defined by one such measurement; however, since the magnetic field is parallel to the sensor coaxial conductor, two orthogonal measurements must be taken to resolve the magnetic field.

Electromagnetic field measuring technique to assess shielding

An electrically conductive block assembly is provided for positioning contact pins in an electrical connector and dissipating high energy voltage pulses to a ground. A voltage variable material is used to space the pins out of direct contact with the block. The block is in electrical communication with a grounded electrical connector housing. High voltage pulses to the contact pins will divert into the voltage variable material, through the block and to the grounded housing.
