Problems solved by technology

However, in the use of the current angular displacement sensors, most of them use a resistor connected in series at both ends of the angular displacement sensor to realize the function of the angular displacement sensor. The angular displacement sensor with an external resistor connected to the sensor can bring a lot of convenience to the actual use of the angular displacement sensor

Embodiment Construction

[0028] like figure 1 and image 3 An angular displacement sensor shown includes a base 2 and a rotating shaft 1 pierced through the base 2 and movably connected with the base 2. The side wall of the base 2 is provided with connecting through holes A21 spaced apart from each other, and connecting through holes A21. Hole B22 and connection through hole C23; the upper end of the rotating shaft 1 is provided with a conductive matrix 3, and the conductive matrix 3 is provided with a resistor body 31, and the resistor body 31 is made of conductive plastic, that is, carbon black is added to the DAP resin. The fabricated resistor body 31. The resistance value of the resistor 31 is related to the content of carbon black in the DAP resin, the higher the content of carbon black, the lower the resistance value. The top of the resistor 31 is provided with a collector ring 4 fixed on the rotating shaft 1, and the collector ring 4 is provided with a multi-finger brush 41, that is, the coll...

Abstract

The invention discloses an angular displacement sensor, which comprises a base and a rotating shaft which penetrates through the base and is movably connected with base, wherein a connecting through hole A, a connecting through hole B and a connecting through hole C which are mutually arranged at intervals are arranged on the side wall of the base, and a conductive substrate is sleeved at the upper end of the rotating shaft; a resistance body is arranged on the conductive substrate, and a collecting ring fixed on the rotating shaft is arranged above the resistance body; a brush is arranged on the collecting ring, and a support fixed on the rotating shaft is arranged above the collecting ring; a first circuit contact, a second circuit contact and a third circuit contact are arranged on the upper surface of the conductive substrate, and the first circuit contact is connected with the end A of the resistance body; the second circuit contact is connected with the end B of the resistance body, and the third circuit contact is connected with the collecting ring through a collecting line; and a first gap is arranged on the resistance body close to the end A of the resistance body. When in use, the invention can realize the proper functions without connecting an external resistance in series, and has simple structure, convenient use, low cost and convenient promotion and use.

Description

technical field [0001] The present invention relates to a sensor, in particular to a high-precision angular displacement sensor for servo equipment with precise electronic and mechanical output performance. Background technique [0002] As the cost of labor is getting higher and higher, and the production equipment is becoming more and more intelligent, the angular displacement sensor is a relatively important component in automatic control and has been more and more widely used. However, in the use of the current angular displacement sensors, most of them use a resistor connected in series at both ends of the angular displacement sensor to realize the function of the angular displacement sensor. The angular displacement sensor with an external resistor connected to the sensor can bring a lot of convenience to the actual use of the angular displacement sensor. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings in the abo...
