Abstract
The invention discloses a bent-wire contact potentiometer. The bent-wire contact potentiometer comprises a base, a resistor body, fixed contacts, a movable contact, a rotating drive plate and a conductive sliding piece; the resistor body is fixed on an end face of the base; the fixed contacts are fixedly arranged at the two ends of the base; the movable contact is arranged between the fixed contacts; one ends of the fixed contacts and the movable contact are connected to the resistor body, respectively; leading-out end contacts are arranged at the other ends of the fixed contacts and the movable contact; through holes are formed in the centers of the leading-out end contacts; a plurality of conductive bent wires are arranged in the through holes; the conductive bent wires are arranged longitudinally in parallel to each other. Through the mode, the bent-wire contacts can be arranged on the potentiometer so that the area of the contacts of the potentiometer is larger, and therefore, the potentiometer has better conductivity and contacting performance.
Description
Technical field
The present invention relates to potentiometer field, particularly relate to a kind of curly wire contact potentiometer.
Background technology
Potentiometer is called again variable resistance, and potentiometer is to have three exits, the resistive element that its resistance can regulate by certain Changing Pattern.Potentiometer conventionally by resistive element and movably brush form.In the time that brush moves along resistive element, obtain the resistance value that becomes certain relation with displacement at output, it is the most common during circuit connects, the most extensive circuit element of use, but potentiometer can cause the loosening situation in contact of contact exit in long-term use procedure, cause that contact performance reduces greatly, make electric current fluctuated, reduced the useful life of carbon-film potentiometer, and then is affected the useful life of whole electric device, impact is normally used.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of curly wire contact potentiometer, and curly wire contact can be set on potentiometer, makes the contact contact point face of potentiometer larger, has more conductibility, and contact performance is better.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of curly wire contact potentiometer is provided, comprise: pedestal, resistive element, fixed touching plate, movable contact spring, revolving dial and conduction slide plate, described resistive element is fixed on described pedestal end face, described pedestal two ends are fixedly installed described fixed touching plate, described movable contact spring is located between described fixed touching plate, described fixed touching plate is connected respectively described resistive element with described movable contact spring one end, described fixed touching plate and the described movable contact spring other end are provided with exit contact, described exit contact central authorities offer through hole, in described through hole, be provided with many conduction curly wires, the opposing parallel setting of longitudinally arranging between described conduction curly wire.
In a preferred embodiment of the present invention, described pedestal central authorities are provided with described revolving dial, and described revolving dial one end connects described movable contact spring, and the described revolving dial other end connects conduction slide plate, and described conduction slide plate connects described resistive element.
In a preferred embodiment of the present invention, described movable contact spring is located at described pedestal centre position, on the pedestal at described movable contact spring two ends, is symmetrical arranged described fixed touching plate.
