Description
Technical field
The utility model is related to field of electrical components, particularly a kind of miniaturization angular displacement sensor.
Background technology
Angular displacement sensor is usually used in precision instrumentation measurement, high-accuracy machine tool, track traffic and weapon
In the fields such as system, it is typically made up of base, shell, rotating shaft, resistive element, brush, travelling arm, exit, afflux part, with
China's armament systems and electronic product develop to the direction of miniaturization, and the demand for minimizing angular displacement sensor is increasing,
This requires that sensor need to be updated, simplify design, reduces volume.
Utility model content
Goal of the invention of the present utility model is：For above-mentioned problem, there is provided one kind miniaturization angle displacement transducer
Device.
The technical solution adopted in the utility model is as follows：
One kind miniaturization angular displacement sensor, it is characterised in that including base and rotating shaft, the rotating shaft passes through bearing and card
Circle is fixed in base, and the rotating shaft one end extending into base is provided with circuit board, and brush is provided with circuit board；The base
Interior setting resistor disc, in resistive band and the dual-attenuation structure of conductive strips symmetry arrangement, the brush can be in the band of rotating shaft for resistor disc
Being slided on resistor disc under dynamic produces output signal to be exported through exit.
Further, the brush is fixed on the offside on circuit board the same face.
Further, the brush is mutually 180 ° of angles.
Further, the resistor disc is the dual-attenuation structure of resistive band and conductive strips symmetry arrangement.
In sum, by adopting the above-described technical solution, the beneficial effects of the utility model are：Circuit board is used as " absolutely
Edge set " plays electrical isolation in the sensor, makes all the time in good state of insulation between brush and rotating shaft, as " sliding
The mechanical movement of rotating shaft is passed to brush by swing arm ", while the output voltage of brush is passed to exit, is which reduced absolutely
The correlated parts such as edge set, reed, afflux part, in the case of the identical function for completing sensor, the volume of product is reduced product
10%, weight reduction 10%, the structure of sensor is simpler, compact, small volume.

Specific embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
As shown in figure 1, the utility model sensor includes base (2) and rotating shaft (1), rotating shaft (1) is by bearing (3) and card
Circle (7) is fixed in base (2), and base (2) top is provided with shell (8), and one end that rotating shaft (1) is extend into base (2) sets
Circuit board (9) is equipped with, brush (5) is set on circuit board (9), brush (5) can be sliding in resistor disc (10) under the drive of rotating shaft (1)
It is dynamic.Resistor disc (10) is provided with base (2), resistor disc (10) is in resistive band and the dual-attenuation structure of conductive strips symmetry arrangement.
As shown in Fig. 2 the brush (5) is fixed on the both sides on circuit board the same face, 180 ° of angles are mutually, two brushes pass through
Circuit turn-on on circuit board.One end of resistive band sets electrode 1, and the other end sets electrode 3, and one end of conductive strips sets electrode
2, weld lead-out wire respectively on each electrode.Brush produces output voltage when resistor disc surface is slided, and output voltage is by drawing
Terminal (6) passes to extraction component (4).
When rotating shaft (1) rotates, brush (5) is driven to be slided on resistor disc (10), the electrical connection of movable contact is by brush (5)
Movable contact exit is delivered to through circuit board (9), signal output is obtained by exit.Double brush is under the drive of rotating shaft in electricity
Slided on resistance piece and produce output signal, now circuit board plays electrical isolation and acts on as " insulation sleeve ", make rotating shaft and brush it
Between be in good state of insulation all the time, while " travelling arm " effect is served as in rotating shaft, reed, afflux part etc. related zero can be saved
Part.
Used as a kind of preferred embodiment, circuit board is directly bonded in rotating shaft, and brush rivet welding is in circuit board both sides.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
