DEVICE FOR CONNECTION OF PRINTED CIRCUIT BOARDS TO ELECTRIC CIRCUIT TESTER Russian patent published in 1994 - IPC

FIELD: electrical and radio engineering. SUBSTANCE: device has dielectric plate 1 with holes which accommodate spring telescopic contacts 2, baseboard 3 with holes housing lower tails 4 of spring contacts, support columns 5, base plate 6, intake plate 7, guiding pins 8 to mount tested printed circuit board 9, cover 10, ultrasonic composite converters composed of radiating straps 11, standard piezoceramic rings 12, current-conducting spacers 13, reflecting straps 14, coupling pins and nuts, support balls 15 put into holes in cover 16, switch 17 which output 18 are connected to current-conducting spacers 13 of generator 19 which output is coupled to input of switch, connecting wires 20, power controller 21. Converters are fastened to covers by screws screwed into coupling pins. Converters are installed in cover with clearance providing for lack of any acoustic coupling between converters. EFFECT: enhanced operational efficiency and reliability. 2 cl, 1 dwg
