Abstract

FIELD: electrical equipment, such as adjusting resistors; miscellaneous radio electronic devices. SUBSTANCE: variable-resistor assembly has resistive unit built up of at least two layers with two relevant fixed current contacts in the form of heat and current conducting plate; resistive unit is mounted on plate so that its layers are arranged one on top of other and one of layers or both are trapezoidal in shape as viewed from top with straight or curved sides. Material of first layer applied directly on plate has volume resistivity at least twice as high as that of second layer material applied above first one. First resistive layer may be located in cavity made in plate and trapezoidal-shaped sides may be made as second-order curve sections. EFFECT: improved dissipation power at rather small size and simple design. 4 dwg

Изобретение относится к электрическому оборудованию, в частности к регулируемым резисторам, и может быть использовано в различных радиоэлектронных устройствах. Узел переменного резистора имеет большую мощность рассеяния при сравнительно малых габаритных размерах и простой конструкции. Узел переменного резистора содержит резистивный элемент, выполненный по меньшей мере из двух слоев с двумя связанными с ним неподвижными токовыми контактами, выполненными в виде пластины из теплопроводного электропроводного материала, причем резистивный элемент размещен на пластине таким образом, что его слои расположены один на другом, один из слоев или оба имеют в плане трапецеидальную форму с прямыми или кривыми боковыми сторонами. Материал первого нанесенного непосредственно на пластину слоя имеет удельное объемное электрическое сопротивление по меньшей мере в два раза больше, чем удельное объемное электрическое сопротивление материала второго слоя, размещенного на первом. Первый резистивный слой может быть расположен в углублении, выполненном в пластине, а боковые стороны трапецеидальной формы могут быт выполнены в виде участков кривых второго порядка. 4 ил.The invention relates to electrical equipment, in particular to adjustable resistors, and can be used in various electronic devices. The variable resistor assembly has a large dissipation power with relatively small overall dimensions and a simple design. The variable resistor assembly comprises a resistive element made of at least two layers with two fixed current contacts connected to it, made in the form of a plate of thermally conductive electrically conductive material, the resistive element being placed on the plate so that its layers are located one on top of the other, one of the layers or both are trapezoidal in plan with straight or curved sides. The material of the first layer deposited directly on the plate has a specific volumetric electrical resistance of at least two times greater than the specific volumetric electrical resistance of the material of the second layer placed on the first. The first resistive layer can be located in the recess made in the plate, and the sides of the trapezoidal shape can be made in the form of sections of the curves of the second order. 4 ill.
