POWER LEAD-IN OF SEALED CHAMBER Russian patent published in 1995 - IPC

FIELD: radio electronics. SUBSTANCE: power lead-in has radio electronic module 1 put into shell 2 made from structural dielectric based on alumoxide ceramics, for instance, other device 3 electrically connected to A.C. source and to information source and user, dismountable magnetic circuit of transmission of power from A.C. source to elements of sealed module composed of two halves with primary 4 and secondary 5 windings, magnet 6 made from ferromagnetic material with definite Curie point, sealed contact 7 and dismountable magnetic circuits of lead-in into module 1 and output of information from it with primary 8,9 and secondary 10,11 windings coupled correspondingly to sources of information input into module 1, to output of module 1, to input of module 1 and to information user via sealed contact 7. Power supply to sealed module as well as exchange of information signals with it are carried out by contactless method thanks to presence of electromagnetic coupling of dismountable magnetic circuits and to manufacture of shell 2 from structural dielectric material. In compliance with invention when temperature inside shell 2 reaches value of Curie point automatic disconnection of information user from output of module 1 takes place by means of loss of ferromagnetic properties of magnet 6 and breaking of sealed contact 7. EFFECT: expanded functional capabilities and application field, enhanced authenticity of contactless exchange of information between sealed radio electronic module and other device. 1 dwg
