Изобретение относитс  к контактным устройствам и предназначено дл  использовани  при измерении слаботочных параметров изделий в полупроводниковой промышленности.The invention relates to contact devices and is intended for use in the measurement of low-current parameters of products in the semiconductor industry.

Известны электромагнитные измерительные устройства, состо щие из катушки электромагнита и подвижного сердечника любой формы. Такие электромагнитные устройства с подвижным сердечником характеризуютс  ИЕ1тенсивным износом из-за частого срабатывани .Electromagnetic measuring devices are known, consisting of an electromagnet coil and a moving core of any shape. Such a moving-core electromagnetic device is characterized by its intense wear and tear due to frequent operation.

Дл  ускорени  процесса измерени  контактные стержни предложенного устройства расположены внутри электромагнита неподвижно и отделены от его сердечника прокладкой.To speed up the measurement process, the contact rods of the proposed device are located inside the electromagnet stationary and separated from its core by a gasket.

На чертеже изображено предлагаемое устройство .The drawing shows the proposed device.

Устройство состоит из двух катушек 1, 2 электромагнита. Кажда  катушка имеет неподвижный сердечник, состо щий из втулки 3, выполненной из магнитного материала (прижимна  часть), контактного стержн  4 из материала с малым удельным сопротивлением (измерительна  часть) и прокладки 5 из диэлектрика дл  устранени  токов утечки.The device consists of two coils 1, 2 electromagnet. Each coil has a fixed core consisting of a sleeve 3 made of magnetic material (pressure part), a contact rod 4 of a material with low resistivity (measuring part) and a dielectric gasket 5 to eliminate leakage currents.

Стержни 4 подключены к электроизмерительному прибору 6.The rods 4 are connected to an electrical measuring device 6.

При подаче контролируемой детали 7 к устройству запитываютс  катушки 1, 2 электромагнита и прижимают деталь к стержн м 4, через которые подаетс  коммутируемый ток от электроизмерительного прибора 6. Происходит измерение параметра. По окончании измерени  катушки 1, 2 элек7ромагнита обесточиваютс , и изделие попадает в устройство сортировки.When the monitored part 7 is supplied, the coils 1, 2 of the electromagnet are fed to the device and the part is pressed to the rods 4, through which the switched current from the electrical measuring device 6 is supplied. The parameter is measured. At the end of the measurement, the coils 1, 2 of the electromagnet are de-energized, and the product enters the sorting device.
