A grounding plate having a flanged edge wall continuously around its periphery is press fit into the open end of a connector part shell. The plate provides a continuous intimate contacting relationship between the plate flange and the inner wall of the connector shell. A plurality of openings are formed in the plate aligned with the connector contacts contained within the connector part. A length of shielding braid, which can be identical to that carried by a cable wire has one open end soldered onto a cable wire shield. A metal ferrule grounding plug has an open end which is soldered or otherwise electrically and mechanially secured to the other end of length of shield braid. The outer end of the grounding plug has a radially outwardly directed flange and a slotted side wall, such that the plug on being inserted into a grounding plate opening is compressed, and then when the flange has passed through the plate it snaps outwardly to lock the plug in place. An alternative form includes a removable grounding plate held within the connector part end by an end cap or connector shell extender.

Cable shield termination for an electrical connector

A non-intrusive, annular, broad range current sensor is located about the transmission line at the shorting location of the shielding device. Effectiveness of the shielding of the device can be readily determined for any particular predetermined frequency or range of frequencies by noting the current sensor readings and output voltage. That is, the lower the output voltage/sensor voltage readings in the test frequency range, the higher the shielding effectiveness of the device.

Coaxial test fixture for determining shielding effectiveness of a device

A current detection device has an annular dielectric substrate with a thin (e.g., less than one skin depth at maximum frequency) resistive foil laid down on the substrate outer surface and extending completely thereabout. Annular metal rims are affixed to the substrate edges respectively contacting the metal foil or film. A conductive strip of appropriate dimensions is received onto the outer edges of the metal rims and extends about the complete circumference of the rims. A resistive material is used to secure the conductive strip to the edges of the rims so that the entire resistance of the strip and resistance material exceeds that of the sensing metal foil to prevent shorting out of the foil.

Current detection device having an extended frequency range of response

The outer insulation on a cable to be terminated is removed leaving a section of exposed cable shield. An annular metal contact with a deformable circumferential flange is received on the cable and affixed (soldered) to the bare shield completely encircling the shield with a mechanical and electrical connection. A receiving tube slid onto the cable has a contoured end for receipt under the contact flange. A clamping ring is soldered, mechanically or electromagnetically formed over the flange and contoured end of the receiving tube. A cylindrical cap encloses the bare shield section and contact with thin-wall portions being deformed to tightly engage the receiving tube. The cable and outer end of the receiving tube are passed through an opening in a termination plate (e.g., ship deck) and the receiving tube is welded to the plate.

Cable shield termination means

Cable wires to be interconnected by a plug and receptacle connector are received within the end portion of each connector part, the cables themselves being conventionally connected to a pin and socket contacts. The contacts are received within insulative inserts which, in turn, are mounted within metal shell members. A portion of the cable shields outwardly of the insulative inserts are located on the outer end portion of a connector part metal shell surrounding the inserts. A metal ring is placed over the individual cable shields and formed in place mechanically securing and electrically connecting the cable shields to the metal cylinder and thus to the connector part.
