Abstract
The utility model discloses an angle potentiometer, which comprises a substrate and a lead assembly. A rotating assembly is arranged on the substrate and comprises a rotating shaft and a current-collecting sheet arranged on the rotating shaft; a reed is arranged on the current-collecting sheet and provided with an electric brush; the rotating shaft can rotate relative to the substrate; the electric brush moves on a conductive track on the surface of the substrate under the drive of the rotating shaft; and the substrate is connected with the lead assembly through a wire and is made of diallyl phthalate (DAP) resin. The angle potentiometer has the advantages of high linearity, long rotational life, high reliability and the like, has a simple structure and low production cost, and is convenient to use and popularize.
Description
Technical field
The utility model relates to a kind of potentiometer, is specifically related to a kind of angle potentiometer.
Background technology
Along with development of science and technology, potentiometer realizes moving to from machinery the conversion of electronic signal as angular transducer and position transducer, and being widely used in has the complete machine such as Aeronautics and Astronautics of higher technical requirement and precision instrumentation etc. to high accuracy and long-life.In recent years, people wish to produce have linearity height, rotational life is long, reliability is high, degree of regulation is high, flatness is good potentiometer.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of angle potentiometer is provided.Linearity height of the present utility model, long, the reliability advantages of higher of rotational life, and it is simple in structure, easy to use, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of angle potentiometer, it is characterized in that: comprise matrix and lead assemblies, described matrix is provided with runner assembly, described runner assembly comprises rotation axis and the flow collection sheet that is arranged on the rotation axis, described flow collection sheet is provided with reed, described reed is provided with brush, described rotation axis can rotate relative to matrix, described brush moves on the strip conductor at matrix surface under the drive of rotation axis, described matrix is connected with lead assemblies by lead, and described matrix is made by the DAP resin.
Above-mentioned a kind of angle potentiometer also comprises the shell that is arranged on the runner assembly outside.
Above-mentioned a kind of angle potentiometer is arranged with bearing on the described rotation axis, and described bearing is provided with bearing holder (housing, cover).
Above-mentioned a kind of angle potentiometer, described rotation axis is provided with packing ring near matrix one side and with the bearing contact position.
Above-mentioned a kind of angle potentiometer, described rotation axis is provided with collar away from matrix one side and with the bearing contact position.
Above-mentioned a kind of angle potentiometer, described brush are to be made by the hexa-atomic alloy silk of noble metal.
Above-mentioned a kind of angle potentiometer is coated with lubricating oil on the described strip conductor.
The utility model compared with prior art has the following advantages: linearity height of the present utility model, long, the reliability advantages of higher of rotational life, and it is simple in structure, easy to use, production cost is low, is convenient to promote the use of.Because matrix is made by the DAP resin, because the DAP resin is very excellent in the performance of aspects such as electrical characteristic, dimensional stability, thermal endurance, moisture-proof and chemical stability, its polymer film densification, any surface finish are like mirror.The resistance to wear of this resistive element is outstanding, and rotational life can reach up to ten million times, and its flatness is good, contact reliability is good, resolving power is high.Brush of the present utility model is selected the elasticity hexa-atomic alloy silk making of noble metal preferably for use, has good resistance to wear, is coated with lubricating oil on the described strip conductor, has guaranteed brush and strip conductor excellent contact, and has further improved its anti-wear performance.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
