H.F. screening for electrical systems - has connectors with mu-metal screen to reduce magnetic reluctance between inner and outer surfaces of screen

The device provides an interconnection between two parts of an annular electrically conductive screen and incorporates an arrangement for reducing the magnetic reluctance of the magnetic path between the inner and outer surfaces of the screen in the region of the interconnection. Improvement in connector screening is possible by separation of the two contact rings combined with a reasonable length of separate conducting paths. Further improvements can be made by insertion of a high permeability magnet material such as a small toroid of laminated mu-metal between the conducting paths. L'INVENTION CONCERNE LA CONNEXION DU BLINDAGE DES CONNECTEURS.ELLE SE RAPPORTE A UN CONNECTEUR DANS LEQUEL DEUX JUPES FENDUES 6, 7 COOPERENT AVEC DEUX JUPES PLEINES 10, 11 AU NIVEAU DE CONTACTS ANNULAIRES 12, 14. SELON L'INVENTION, LA RELUCTANCE MAGNETIQUE ENTRE LES CONTACTS 12, 14 EST REDUITE PAR DISPOSITION D'UN ELEMENT TOROIDAL 15 AYANT UNE PERMEABILITE MAGNETIQUE ELEVEE, ENTRE LES DEUX JUPES 6, 7.APPLICATION A LA CONNEXION DU CONDUCTEUR EXTERNE DES CABLES BLINDES.
