(54) БЕСКОНТАКТНОЕ РЕЛЕ(54) NON-CONTACT RELAY

II

Изобретение относитс к электротехнике и может быть использовано в схемах контрол учета и управлени производственными процессами, например в устройствах контрол скорости движени конвейерной ленты.The invention relates to electrical engineering and can be used in control circuits for recording and controlling production processes, for example, in devices controlling the speed of a conveyor belt.

Известны бесконтактные реле, содержащие два сердечника, между которыми образована рабоч-а щель, и узел управлени , выполненный в виде пластины с круглыми отверсти ми и с центрами на оси симметрии магнитной системы 1.Contactless relays are known, which contain two cores, between which a working-slit is formed, and a control unit, made in the form of a plate with round holes and with centers on the axis of symmetry of the magnetic system 1.

Однако область применени таких реле ограничена.However, the scope of such relays is limited.

Известны также бесконтактные реле, содержащие генератор автоколебаний, включающий в себ контурные обмотки, размещенные в броневом ферритовом сердечнике со средним стержнем переменного сечени , выполненным со сквозным осевым отверстием и узел управлени , включающий в себ основание и переключающий элемент, размещенный на основании 2..Contactless relays are also known that contain a self-oscillation generator, including contour windings placed in an armored ferrite core with a medium variable cross-section rod, made with a through axial bore, and a control unit including a base and a switching element located on the base 2.

В таких реле отсутствует регулировка длительности включенного состо ни , они обладают ограниченными функциональными возможност ми и значительным весом.In such relays, there is no adjustment of the duration of the on state; they have limited functionality and considerable weight.

Цель изобретени - обеспечение регулировки длительности включенного состо ни , расширение функциональных возможностей и уменйщение веса.The purpose of the invention is to provide adjustment of the duration of the on state, expansion of functionality and weight reduction.

Claims

For this purpose, in a contactless relay containing a self-oscillation generator, including contour windings placed in an armored ferrite core with a medium variable cross-section rod, made with a through axial bore, and a control unit including a base and a switching element disposed on the base, the base of the control unit is made of a flexible dielectric sheet material, and the switching element of the control unit is made in the form of short-circuited coils of a material with high conductivity Strongly and flat springs sawtooth shape of conductive material, said flat springs are electrically coupled together through said squirrel-cage coils, the diameter of the short-circuited turns equal to the minimum diameter of the middle section of the ferrite core rod armor. FIG. 1 shows a control unit for a contactless relay; in fig. 2 - contactless relay. The contactless relay comprises a control unit including a base 1 of a flexible dielectric sheet material and a switching element including short-circuited coils 2 of a material with high conductivity and flat springs 3 and 4 of a sawtooth shape of conductive material. The flat springs 3 and 4 are interconnected through short-circuited coils 2, the diameter of which is equal to the diameter of the minimum cross section of the middle rod 5 of the armored ferrite core 6 having a through axial bore. Contour windings 7 are placed on the armor ferrite core 6. The flat springs 3 and 4 under the influence of the applied force can change their shape. The flow through the loop windings 7 of the loop current generating oscillations creates an alternating magnetic field, the intensity of which determines the magnitude of the sensitive zone capable of reacting. When the control unit introduces a moving organ, due to mutual induction in short-circuited coils 2, an electromotive force (EMF) is induced which causes current to flow and thus the appearance of a magnetic flux opposite to the flow of the self-oscillation generator, causing the inductive coupling of the generator windings to break, causing a non-contact relay to another discrete state. A non-contact relay comprising a self-oscillation generator including contour windings placed in an armored ferrite core with a medium variable cross-section rod, made 1-1 with an axial bore through hole, and a control unit including a base and a switching element spaced by basis, characterized in that, in order to ensure adjustment of the duration of the on state, expansion of functionality and weight reduction, the base of the control unit is made of flexible the dielectric sheet material, and the switching element of the control unit is made in the form of short-circuited turns of highly conductive material and flat saw-shaped springs of conductive material, said flat springs are electrically connected to each other through said short-circuited turns, the diameter of short-circuited turns equal to minimum cross-section of the middle rod of the armored ferrite core.
