DEVICE FOR ELECTROMAGNETIC SHIELDING OF CONTACT CONNECTION OF HOUSINGS OF RADIOELECTRONIC EQUIPMENT Russian patent published in 2018 - IPC H05K9/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the field of radio engineering, in particular the protection against electromagnetic interference of radio electronic equipment, and can find application in the creation of radioelectronic equipment with increased efficiency of shielding the contact end connection of detachable housings. Claimed device for electromagnetic shielding of a contact connection of electronic equipment housings comprises metal housing 1 and reciprocal removable cover 2, on surface 3 of which an ultra-wideband mode-impedance phase-inverter is made, consisting of the first cavity resonator 13 in the form of a rectangular ring and the second cavity resonator 19 in the form of a parallelepiped, additional open cavity resonator 26 of rectangular cross-section in the form of a rectangular ring which is installed without galvanic contact inside the first cavity resonator 13, one 7 and the other 8 U-shaped spring metal contact strips are mounted on side walls 30 and 32 of additional cavity resonator 26, the second open additional cavity resonator 44 of rectangular cross-section in the form of a rectangular ring, in which additional metal spring contact strip 46 is mounted, the third additional open cavity resonator 51 of rectangular cross-section in the form of a rectangular ring.

EFFECT: increase in the effectiveness of electromagnetic shielding of the contact connection of metal housings of electronic equipment in a wide frequency range with a high degree of reliability of the contact connection.
