Container, resistor etc. constitute resonance circuit.So as to be widely used the crowds such as radio communication, radio frequency, frequency modulation, radar transmitter
Many technical fields, therefore the inductor design demand of all size, parameter just occurs, therefore controllable impedance arises at the historic moment.
At present adjustable electric sensor is mainly by following several technical approach realizing：1. by adjusting magnetic core in inductance
Position in coil changes realizing inductance value, and the usual inductance value range of accommodation of controllable impedance of this kind of method design is less；2.
The number of turn for changing inductance coil using slide switches realizes that inductance value changes, the usual volume of controllable impedance of this kind of method design compared with
Greatly；3rd, by 2 windings of coiling on magnetic core, a Working winding leads to exchange, and a controling winding leads to direct current, by control
The size of controling winding DC current is flow through so as to realize the change of inductance value.The controllable impedance structure of this kind of method design is multiple
It is miscellaneous, in addition it is also necessary to increase degausser in circuit, it is unfavorable for the control of production cost, and relative volume is larger is unfavorable for product
Layout arrangement.

Moving axis, the axis of rolling two ends are provided with retention mechanism, and the retention mechanism is arranged on the supporting plate, and the axis of rolling is provided with one
The recessed wheel that can be slided along the axis of rolling, the recessed wheel are nested on the circle line of the coil, and the recessed wheel can be rotated with coil.
Preferred as one kind of this programme, the retention mechanism includes cutting reed and compresses shell fragment, the incision reed
Axis of rolling end is cut radially, the compression shell fragment compresses incision reed.
Know-why：The present invention provides a kind of controllable impedance, by rotating drive shaft, drives insulating cylinder body and coil rotation
Turn, the recessed wheel of embedded coil turn line is rotated with coil, and move on the axis of rolling, by the present invention in that coil sections are in short
Line state, to realize the lasting adjustable of inductance.
The invention has the beneficial effects as follows：
1st, design of the present invention using rotating coil, rotates the change for realizing inductance value by coil, not only simplify inductance knot
Structure, and flexible adjustment is convenient.
2nd, the present invention adopt adjustable pressing device to keep roller and coil case to be brought into close contact, without the phenomenon such as virtual connection is tactile,
With higher reliability, while scroll wheel freedom and flexibility, realize the continuously adjustabe of controllable impedance inductance value.
3rd, small volume of the present invention, simple structure are easy for installation, optimize Conventional tunable inductance adjustment device and are oriented to dress
Put, reduce manufacture and the difficulty installed.
