Description
Изобретение относитс к электротехнике и может быть использовано при -изготовлении контактных элемен , тов. Известен переменный резистор, В котором подвижный токосъемный элемент выполнен как контакт скольжени по резистивному слою DlОднако известный переменный резис тор обладает сравнительно низкой надежностью вследствие износа резистив ного сло при скольжении токосъемного контакта. Другим недостатком в л ютс шумы, создаваемые в зоне контакта токосъемного элемента и резистивного сло при перестройке резистора . Наиболее близким по технической сущности к предлагаемому вл етс ре зистор, содержащий два роликовых кон такта, один из которых перекатываетс по резистивному, а другой по токосъе ному элементам 2. Однако он обладает сравнительно низкой надежностью за счет износа резистивного элемента при перекатьтании по нему роликового контакта. Цель изобретени - повьшение надежности контактировани . Поставленна цель достигаетс тем, что известный резистор, содержащий корпус, размещенные в нем резистивные элементы и расположенные между ними прижимные ролики, перемещающиес вдоль поверхности резистивных элементов , он дополнительно снабжен упругой токопровод щей лентой, охватывающей прижимные ролики, с возможностью ее контактировани с поверхностью резистивных элементов. На чертеже представлена конструкци переменного устройства резистора. Резистор содержит корпус 1, на внутренних параллельных поверхност х которого расположены два рнзистивных элемента 2, соединенных с электрическими выводами 3, прижимные ролики 4,The invention relates to electrical engineering and can be used in the manufacture of contact elements, Com. A variable resistor is known, in which the movable current-collecting element is designed as a sliding contact over the resistive layer. Dl However, the known variable resistor has a relatively low reliability due to the wear of the resistive layer when the current-collecting contact slides. Another disadvantage is the noise generated in the contact zone of the current collector element and the resistive layer during resistor tuning. The closest in technical essence to the present invention is a resistor containing two roller contacts, one of which rolls along the resistive and the other along current-collecting elements 2. However, it has a relatively low reliability due to the wear of the resistive element when the roller contact rolls over it. . The purpose of the invention is to increase the reliability of contact. The goal is achieved by the fact that a known resistor, comprising a case, resistive elements placed in it and pressure rollers located between them, moving along the surface of the resistive elements, is additionally equipped with an elastic conductive tape covering the pressure rollers with the possibility of its contact with the surface of resistive elements . The drawing shows the construction of a variable resistor device. The resistor comprises a housing 1, on the inner parallel surfaces of which there are two resistance elements 2 connected to the electrical leads 3, the pressure rollers 4,
