Description
Technical field
The present invention relates to inductance component technical field, more particularly to a kind of annular are vertical around inductor and its manufacturer
Method.
Background technology
The vertical structure around inductor of annular, be by the loop wire magnetic core cut with stand around quad flat coil assemble.
As shown in figure 1, symmetrical cutting of the toroidal core by instruments such as high speed grinding wheels, magnet ring is cut into the magnetic core 1 of two pieces of semicircular rings, so
The flat copper wire shown in Fig. 2 is stood afterwards and founds coiling 2 around squarely, according to the assembling mode shown in Fig. 2, two halves magnetic core
Insert flat wire to stand inside coiling, then apply bonded adhesives on the cut surface of magnetic core, magnet ring is bonded, form inductance
Device 3.
The core material and copper cash that this inductor is used with it are the most economical, good heat dissipation effect, the parasitism of inductance coil
Electric capacity is small, electromagnetic compatibility effect is good in circuit application, and is favored deeply by Power Engineer.
However, the inductance element that structure as using is assembled into, is inevitably present following problem：
1) to reduce processing cost, cutting technique generally carries out mill using high speed grinding wheel piece and cuts, because grinding wheel thickness compared with
Greatly, the size penalty of core material is big after cutting, and when two halves are spelled back into a magnet ring, actual upper magnetic ring has not been circle,
Do not cause singly the loss of permeability magnetic material to cause the change of inductance value, more diminish because the change of magnet ring size is flat, cause in annular cavity
The wire number of turn being discharged into declines, it is difficult to obtains bigger inductance value；
2) during grinding wheel high speed circumgyration incision, because emery wheel rotates control reason and cutting feeding depth not
Together, easily occur grinding wheel shake so that the cut surface of two halves magnetic core can not keeping parallelism, cause two halves cut after magnetic
After core combination, occur V-type gap 4 as shown in Figure 3, such V-type gap 4, not only easily making magnetic circuit produce serious leakage field
Phenomenon, causes the change of inductance value, and forms the eddy-current loss and electromagnetic compatibility problem of periphery copper cash, can also have a strong impact on magnetic core
Adhesive strength, cause be bonded quality problem；
3) coil assembled using the method for semicircle cutting, each wire are bent to the shape of circular magnetic core by force
Arrangement, wire is around the arrangement crimp of magnetic core arcuation, so that each circle of wire is outwardly formed such as Fig. 4 and Fig. 5 institutes by the center of circle
The pressure along wire to magnetic core inwall shown, these pressure act on along arrangements of conductors direction, notice that force direction is different,
But as shown in Figure 4 and Figure 5, these wire active forces 5 be broken down into horizontal and vertical directions wire effect make a concerted effort 6,
The wire effect of wherein horizontal direction makes a concerted effort 6, acts on toroidal core, as long as magnetic core array intensity is enough, then these active forces
Offset each other, the effect of horizontal direction wire makes a concerted effort 6 to be zero, but the active force of vertical direction is then all acted on cut surface.
And two halves magnetic core is integral by bonding, so the high intensity formd on bonding plane from inside to outside is made a concerted effort, these wires are made
With 6 permanent actions with joint efforts on bonding plane, form this semicircle cutting mode inductor to adhesive strength reliability most
For fatal creep rupture power.
4) in addition to above-described problem, the annular formed using the magnetic core of semicircle cutting is vertical around inductor, also a protrusion
The shortcomings that fatal, it is exactly in the presence of coil elastic force, easily occurs assembling dislocation between two halves magnetic core, inductance assembling is very tired
It is difficult；Even if moreover, assembling bonding after, in order to bonded adhesives baking and curing, it is also necessary to using dry tool two halves magnetic core is kept
The fixed drying of extruding, the substantial amounts of production cost for producing tool and improving such inductor.
