Abstract
To solve problem that is too much variation of inductance value along with frequency variation above 10KHZ working frequency, the invention modifies one framework into four frameworks. After separately winding on each framework, they are placed in inductance box. Two inductance coils on one diagonal line is normal to ground. Two inductance coils on another diagonal line are parallel with ground and are in quadrature each other. All four coils are connected by a way of end of a coil connecting to start of next coil.
Description
Technical field
The present invention relates to produce the instrument of inductance by coil windings.
Background technology
The all coilings on same skeleton of current coaxial type standard inductance box, when inductance value when 40mH is above, the distributed capacitance of himself has influenced frequency of utilization scope, particularly frequency and has brought up to 10KHZ when above, inductance value produces great changes with frequency change.
Summary of the invention
The technical problem to be solved in the present invention is to make inductance box when frequency change, reduced by frequency influence.
In order to address the above problem, take following technical scheme:
To original single standard inductance box, take four coil combination, allow four coils equal the standard inductor value by the inductance value that identical coiling direction is together in series from beginning to end, four coils are placed in the square inductor case wooden case, wherein two coil axises on one group of diagonal are perpendicular to ground, two coil axises on another group diagonal are parallel to ground and mutually orthogonal, four coils are filled out consolidation with plank, height is filled and led up with plank, compress with plank again, and the dowel fixes made from nonferromugnetic material is on wooden case, and remaining head and the tail two ends, four coils series connection backs are welded on two binding posts that are fixed in panel, panel with four screw on wooden case.
Owing to be divided into four skeleton coilings, coil turn greatly reduces, and the interlayer distributed capacitance is just little, and the axis mutually orthogonal is placed between adjacent windings, and the mutual inductance influence is little, therefore makes the standard inductance box frequency characteristic fine.
Because space coordinates have only three directions can quadrature, so always have two coils to want axis to be parallel to each other,, so just have two of 0.25 inductor coils of inductance box indicating value if four coils are all got inductance box indicating value 0.25, their axis are parallel to each other, and its mutual inductance influence is bigger; And when coiling, as the coil around one 0.3 inductance box indicating value: the lead number of turns of first 0.1 indicating value and lead length overall will be far more than the lead number of turns and the conductor lengths of the 3rd 0.1 indicating value.In order to repair the inductance box indicating value, as long as go to repair a coil value, this coil value is unsuitable big, and the coil value is little, Zong lead is just long, it is also longer to repair the used lead of small inductance value like this, and is just convenient to repairing accurate inductance box indicating value; Therefore to take four coil values be respectively 0.1,0.3,0.3,0.3 of inductance box indicating value in the present invention, measure more convenient like this, wherein the coil axis of 0.1 indicating value is parallel to each other with the coil axis of another on the diagonal perpendicular to ground perpendicular to ground.

Fig. 3 is four coil placements of standard inductance box figure
Embodiment
Pass through lead among the figure, by the coil winding direction four independent inductor coils 9 are joined end to end, press Fig. 3 modes of emplacement, be placed in the wooden case 3, wherein the coil of standard inductance box indicating value 0.1 is the parallel and vertical ground of coil axis of standard inductance box indicating value 0.3 with another, be placed on the diagonal two ends of wooden case, the indicating value correction is that 0.1 coil carries out to indicating value only, repair four coil stationary after the standard, two leads that connect binding post pass from 4 holes of the same big plank with wooden case 3 internal volumes, and the pin 8 that nonferromugnetic material is made is fixing, two binding posts 1 are fixed on the panel 2, and respectively with two wire bonds of drawing from plank, be fixed on 3 four angles of wooden case with four screws 10 again.
