Description
Technical field
The present invention relates to a kind of inductance more particularly to a kind of controllable impedances.
Background technology
Inductance as component common in electronic circuit, it acts as AC signal is carried out Isolation or with electricity
Container, resistor etc. form resonance circuit.So as to be widely used the crowds such as radio communication, radio frequency, frequency modulation, radar transmitter
More technical fields, thus just will appear various specifications, parameter inductor design demand, therefore controllable impedance comes into being.
Adjustable electric sensor is mainly realized by following several technical approach at present:1. by adjusting magnetic core in inductance
Position in coil realizes that inductance value changes, and the usual inductance value adjustable range of controllable impedance of such method design is smaller;2.
The number of turn for changing inductance coil using slide switch realizes inductance value variation, the usual volume of controllable impedance of such method design compared with
Greatly;3rd, by 2 windings of coiling on magnetic core, a Working winding leads to exchange, and a control winding leads to direct current, passes through control
The size of control winding DC current is flowed through so as to fulfill the variation of inductance value.The controllable impedance structure of such method design is answered
It is miscellaneous, it is also necessary to increase degausser in circuit, be unfavorable for the control of production cost, and relative volume is larger is unfavorable for product
Layout arrangement.
However, with the continuous subdivision in market, gradually there are a variety of midget inductors for specific application area.
In data system and industrial electronic application, the demand of POL power supply increases, and hair is brought for high-power, small size inductance
Open up opportunity.Meanwhile the requirement of small-sized controllable impedance is also higher and higher, has both required that its is small, efficient, noise is small, is produced into
This is low, while requires its loss low, rapid heat dissipation, electromagnetism interference etc. again.
A kind of inductance is now provided, while ensureing that its is small, inductance is controllable, also makes it have making simply, production
The advantages that at low cost.
Invention content
The object of the present invention is to provide a kind of controllable impedances, using the design of turnable coil, realize the change of inductance value
Change, ensure inductance be continuously adjusted, it is reliable and stable while, it is simple in structure also with small, it is easy for installation, make it is simple,
The advantages such as production cost is low.
For achieving the above object, the technical scheme is that:A kind of controllable impedance, including insulating cylinder body and winding
Coil outside insulating cylinder body, the insulating cylinder body both ends are equipped with transmission shaft along axis direction, and the transmission shaft is respectively placed in two
Relatively-stationary support plate, the transmission shaft can be rotated relative to support plate;Further include a rolling axially set along insulating cylinder body
Moving axis, the axis of rolling both ends are equipped with retention mechanism, and on the supporting plate, the axis of rolling is equipped with one for the retention mechanism setting
The concave wheel that can be slided along the axis of rolling, the concave wheel are nested on the circle line of the coil, and the concave wheel can be rotated with coil.
Preferably, the retention mechanism includes incision reed and compresses shrapnel, the incision reed one kind as this programme
Radially incision axis of rolling end, the compression shrapnel compress incision reed.
Technical principle:The present invention provides a kind of controllable impedance, by rotating drive shaft, drives insulating cylinder body and coil rotation
Turn, the concave wheel of embedded coil turn line is made to be rotated with coil, and moved 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 beneficial effects of the invention are as follows:
1st, the present invention uses the design of rotating coil, and the variation for realizing inductance value is rotated by coil, not only simplifies electricity
Feel structure, and flexible adjustment is convenient.
2nd, phenomena such as present invention uses adjustable pressing device so that idler wheel and coil case to be kept to fit closely, and no virtual connection is touched,
With higher reliability, while scroll wheel freedom and flexibility, realization controllable impedance inductance value are continuously adjusted.
3rd, the present invention is small, simple in structure, easy for installation, optimizes Conventional tunable inductance adjustment device and is oriented to dress
It puts, reduces the difficulty of manufacture and installation.
