Description

Conductive plastics center tap angle displacement sensor

Technical field

The utility model belongs to sensor technical field, particularly relates to a kind of conductive plastics center tap angle displacement sensor.

Background technology

At present, the function of displacement transducer is that a straight line or annular mechanical displacement convert electric signal to, by variable leading moulded the fixed position of resistance slide rail fixation at sensor, measure different resistance values by the displacement of brush plate on slide rail, voltage between brush plate and the sensor top is directly proportional with the angle that brush plate moves.Conventional angle displacement sensor design generally all designs the effective electric angle that needs, and gamut has only preceding zero-bit and back zero-bit, single input and input voltage terminal.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of conductive plastics center tap angle displacement sensor of importing two voltages.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of conductive plastics center tap angle displacement sensor is provided, comprises tightening up ring, exit, the precision resistance matrix, housing, axle, bearing, brush, axle sleeve, lid, collector ring, afflux arm and two afflux silks, described precision resistance matrix are long around 320 ° of circumference, draw the center tap terminal on its central point, its other two end points are drawn tap terminal and tap terminal.

Beneficial effect

The utility model provides a kind of conductive plastics center tap angle displacement sensor of importing two voltages, and is simple in structure, easy to use.

Embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

The utility model needs 320 ° of corner centers of effective electric stroke that one voltage leading-out ends is set, promptly become 2 * 160 ° of electric ranges, when brush plate position during at 160 °, when the center tap terminal is shared as preceding zero-bit, 320 ° of the effective electric stroke of original sensor promptly are convertible into the angular transducer of 2 * 160 ° of electric strokes, when brush plate by the rotating shaft displacement, up time just or the inverse time timing, two groups of sensors that are respectively 160 ° of effective electric strokes have been changed in practice.Can control required front and back of mechanical displacement or side-to-side movement amount, when 160 ° of centers of brush plate, be the control holding state.

As shown in Figure 1, the utility model comprise tighten up the ring 1, exit 2, precision resistance matrix 3, housing 4, axle 5, bearing 6, brush 7, axle sleeve 8, lid 9, collector ring 10, afflux arm 11 and two afflux silks 12, screw 13, as shown in Figure 2, precision resistance matrix 3 described in the utility model is long around 320 ° of circumference, draw center tap terminal 16 on its central point, its other two end points are drawn tap terminal 14 and tap terminal 15.

Claims

1. a conductive plastics center tap angle displacement sensor comprises tightening up ring (1), exit (2), precision resistance matrix (3), housing (4), axle (5), bearing (6), brush (7), axle sleeve (8), lid (9), collector ring (10), afflux arm (11) and two afflux silks (12) is characterized in that: described precision resistance matrix (3) is for long around 320 ° of circumference, draw center tap terminal (16) on its central point, its other two end points are drawn tap terminal (14) and tap terminal (15).
