Abstract
The utility model discloses a kind of high-precision slide rheostat, form primarily of insulating support, the resistance wire scribbling insulating barrier, slide plate, contact slideway, resistance wire binding post, slide plate binding post, Metallic rod and label, described contact installation of slide track is between two insulating supports, contact slideway is provided with the resistance wire scribbling insulating barrier, the resistance wire two ends scribbling insulating barrier are provided with resistance wire binding post, be provided with Metallic rod above contact slideway, Metallic rod is provided with label, is provided with slide plate on the downside of label.The utility model high-precision slide rheostat still has the traditional function of dividing potential drop, but with common high-precision slide rheostat unlike, the adjustable range of voltage is original half.And along with slide plate slides between the two ends of coil, voltage intersegmentally all can accomplish unidirectional continuously adjustabe each, independently of one another, is independent of each other.It has structure simple, design ingenious and demonstrate advantage easily.
Description
Technical field
The utility model belongs to rheostat field, is specifically related to a kind of high-precision slide rheostat.
Background technology
High-precision slide rheostat is a critical elements in circuit, and it can change self by the position of mobile slide plate
Resistance, thus the effect playing control circuit.In circuit analysis, high-precision slide rheostat both can as a fixed value resistance, also can as a resistance-changing resistor.Its operation principle changes resistance by the length of change place in circuit partial ohmic line, thus change the size of current in circuit gradually.The rheostatic resistance wire of high-precision slide is generally that fusing point is high, the nichrome that resistance is large, and Metallic rod is generally the metal that resistance is little, so when resistance cross section area one timing, resistance wire is longer, and resistance is larger, and resistance wire is shorter, and resistance is less.The rheostatic formation of high-precision slide of the prior art generally comprises binding post, slide plate, resistance wire, Metallic rod and porcelain cylinder etc., because the resistance wire winding zone on porcelain cylinder does not arrange protective cover, is easily subject to human factor on the impact of resistance, falls
The low rheostatic accuracy of high-precision slide and stability.
Utility model content
The purpose of this utility model is to provide a kind of high-precision slide rheostat, solves the deficiency existed in such scheme.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of high-precision slide rheostat, form primarily of insulating support, the resistance wire scribbling insulating barrier, slide plate, contact slideway, resistance wire binding post, slide plate binding post, Metallic rod and label, described contact installation of slide track is between two insulating supports, contact slideway is provided with the resistance wire scribbling insulating barrier, the resistance wire two ends scribbling insulating barrier are provided with resistance wire binding post, be provided with Metallic rod above contact slideway, Metallic rod is provided with label, is provided with slide plate on the downside of label.
Described Metallic rod two ends are provided with slide plate binding post.
With the resistance wire joint scribbling insulating barrier on the downside of described slide plate.
The utility model the utility model high-precision slide rheostat still has the traditional function of dividing potential drop, but with common high-precision slide rheostat unlike, the adjustable range of voltage is original half.And along with slide plate slides between the two ends of coil, voltage intersegmentally all can accomplish unidirectional continuously adjustabe each, independently of one another, is independent of each other.It has structure simple, design ingenious and demonstrate advantage easily.
