Description

A kind of controllable impedance
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.
Description of the drawings
Fig. 1 is the structural diagram of the present invention;
Fig. 2 is the partial enlarged view of retention mechanism in Fig. 1.
Specific embodiment
The technical solution in the embodiment of the present invention is clearly and completely described below in conjunction with attached drawing.
As shown in Figs. 1-2, a kind of controllable impedance, it is described including insulating cylinder body 1 and the coil 2 being wrapped in outside insulating cylinder body 1 1 both ends of insulating cylinder body are equipped with transmission shaft 3 along axis direction, and the transmission shaft 3 is respectively placed in two relatively-stationary support plates 4, institute Stating transmission shaft 3 can rotate relative to support plate 4;Further include the axis of rolling 5 axially set along insulating cylinder body 1, the axis of rolling 5 A concave wheel 6 that can be slided along the axis of rolling 5 is equipped with, the concave wheel 6 is nested on the circle line of the coil 2, and the concave wheel 6 can be with Coil 2 rotates, and 5 both ends of the axis of rolling are equipped with retention mechanism 7, and the retention mechanism 7 includes the incision being arranged in support plate 4 Reed 8 and compression shrapnel 9, the incision reed 8 radially cut 5 end of the axis of rolling, and the compression shrapnel 9 compresses incision reed 8, Make the axis of rolling 5 close to coil 2, to ensure that concave wheel 6 is fitted closely with coil 2.
During work, rotating drive shaft 3 drives insulating cylinder body 1 and coil 2 to rotate, and the concave wheel 6 of 2 circle line of embedded coil is with line 2 rotation of circle, and moved on the axis of rolling 5, coil sections 2 is made to be in short-circuit condition, to realize the lasting adjustable of inductance.
Described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on the present invention In embodiment, the every other implementation that those of ordinary skill in the art are obtained without making creative work Example, belongs to the scope of the present invention.
