Inductor is as a kind of conventional magnetic element, and it act as the elements such as filtering, inhibition peak voltage and peak current, protection switch pipe, rectifying tube and electric capacity composition resonant circuit etc.Thereby be widely used numerous technical fields such as radio communication, radio frequency, frequency modulation, radar transmitter.Therefore just there will be the inductor design demand of all size, parameter, this has just increased employee's workload and the workload of handling of goods and materials, increases design cost, and handling of goods and materials cost, also can cause warehousing pressure.
In order to reduce design cost and handling of goods and materials cost, to reduce stock, the approaching inductor (as from tens microhenrys to hundreds of microhenry) of many kinds of parameters can substitute with a kind of adjustable inductor, can also solve some needs because of special occasions as airborne, Shipborne Electronic Equipment, therefore adjustable inductor just arises at the historic moment, adjustable electric sensor is mainly realized by following several technical approach at present: 1. realize inductance value variation by adjusting the position of magnetic core in inductance coil, the common inductance value adjustable range of controllable impedance of this kind of method design is less; 2. the number of turn that adopts slide switch to change inductance coil realizes inductance value and changes, and the common volume of controllable impedance of this kind of method design is larger; 3, by 2 windings of coiling on magnetic core, Working winding is logical to be exchanged, and controls the perfectly straight stream of winding for one, thereby realizes the variation of inductance value by the size that control winding direct current is flow through in controls.The controllable impedance complex structure of this kind of method design also need to increase degausser in circuit, be unfavorable for the control of production cost, and relative volume is unfavorable for more greatly the layout arrangement of product.
For above-mentioned situation, provide a kind of novel inductor, with lower production cost; Less volume; Higher reliability, the adjusting that realizes inductance value is the problem that prior art need to solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of novel adjustable electric sensor, with lower production cost; Less volume; Higher reliability, realizes the adjusting of inductance value.
For achieving the above object, the technical solution of the utility model is that a kind of novel adjustable electric sensor, is characterized in that: described inductor is that magnetic core coil is enclosed within base, and magnetic core coil side is provided with permanent magnet and contacts with magnetic core coil; Shell entangles permanent magnet and ferromagnetic coil and base and fixes, thereby changes coil magnetic field intensity around to reach the adjustable object of inductance value by rotating permanent magnet.
Between described shell and permanent magnet, be provided with fixation spring tab.
Described shell is provided with two clips and a permanent magnet stopper slot.
Described base is provided with two pins, two holddown grooves and a magnetic core coil stopper slot.
Described magnetic core coil is made up of an I-shaped ferrite magnetic core and a coil.
Described permanent magnet is cylindrical shape, is provided with the harmony groove of in-line at an end face.
Described fixation spring tab is circular, and centre is provided with a circular harmony hole.
A kind of novel adjustable electric sensor, owing to adopting above-mentioned structure, the utility model not only can reduce design cost, handling of goods and materials cost, reduce stock, solve some has higher reliability because of the needs of special occasions, can also sinking production cost, enhance productivity and good looking appearance.
