The another alternative of the choke coil of current compensation is shown in Figure 15 to 17.Herein six shape camber members in order to
It further increases packing density and/or reduces external dimensions and be equipped with impression (Pr gung) in determining region, thus in annular
The cross-sectional configuration of conductors in the inner opening of core 1501 is circle section (cake is block-shaped) and the top in toroidal cores
It is flattened with lower section, i.e. on two end sides of toroidal cores.This allow that the inner opening with conductors is also better abundant
It uses, this realizes the smaller internal holes of core in the situation of identical conductors cross.Flattening at end side reduces
The height of entire component, this generally leads to the smaller size of choke coil.Conductors 1502 to 1507 can at this on side (example
Such as lower section) it is orientated at an angle far from toroidal cores central point relative to radial direction again, go out as shown in Figure 15, and
And on another side (such as top) but it is as shown in Figure 17 accurately radial oriented.It is clear that so close
Filling situation in, conductors as example by paint layer (as example in the situation of copper paint wire rod) or plastics jacket by it is electric absolutely
Edge.
The conductors of the shape with cross section amendment (Querschnittsmodifikation) are shown in FIG. 18
1801 are specifically illustrating, as can obtain in its such as component shown in Figure 15 and 16 using.There are two the tools of conductors 1801
End conductor section 1802 and 1803, wherein end conductor section 1802 bends to S-shaped, thus two end conductor sections 1802
It is arranged parallel to each other with 1803.Two end conductor sections 1802 and 1803 are so spaced apart herein, so that it is being assembled
Not only being spaced from each other in the radial direction in the peripheral direction of toroidal cores but also in toroidal cores after at the toroidal cores.In addition,
The cross section of conductors 1801 is configured to circular sector in the region of the inner opening of toroidal cores (not shown) 1804.In addition, leading
The cross section of body part 1801 is in the area of U-bend bent (its in the state of assembly in toroidal cores at the end side of circuit board)
Towards external flattening in domain 1806.In addition, S-shaped curved region 1805 of the cross section of conductors 1801 between two bendings
In two sides flatten.Cross section in the region of end conductor section 1802 and 1803 can be on the contrary it is round, such as example
In the region of welded eye, however can also (approximation) shrilly lead in the drilling for being preferably introduced into welded eye.Other
In alternative, toroidal cores can be surrounded by plastic casing, for example using fixed pinprick, the convex nose of guidance, card at the plastic casing
Latch hook etc., this is also such as shown in Figure 10,15 and 17.
The assembly or bending of conductors can be realized with mode in different forms herein.On the one hand, conductors can be linearly
Construction, and so individually plug can pass through the internal holes of toroidal cores and most end form is bent to by subsequent bending step
Shape.When all conductors are bent in final shape, these conductors can be oriented and snap onto fixed pinprick.It is another
The conductors of any predeformation also can be used in aspect.Such as can assemble U-shaped conductors and can be then by the conductors direction
Internal end conductor section is brought into desired S-shaped.Another possibility is that using pre- towards end conductor section S-shaped
The conductors of deformation, plug take in final shape by inner opening and then via U-bend song.In order to be bent, close
Suitable tool can be placed at toroidal cores.It is preferably used in the situation in the choke coil of current compensation with higher using
Magnetic permeability soft magnetism toroidal cores, to realize higher decaying (D mpfung) with less coil.In this regard, for example using μ
>=40.000, such as also > 80.000 magnetic permeability.
The bow of very thin protective layer (such as the core slot (Kerntrog) being made of insulating materials) is had in toroidal cores
The combination of the biasing of the advantages of shape part solution and the connecting portion at the outer peripheral edge of toroidal cores and the core contacted with this
The minimum of internal holes leads to very small magnetic core, that is to say, that the core with smaller size smaller, lower weight and smaller cost,
And therefore cause lesser choke coil and shorter length of wires, this causes lesser copper impedance again
(Kupferwiderstand).The reduction of gauge or diameter of wire is possible as a result, this makes slightly lesser core, lesser heavy again
Amount and lesser cost are possibly realized.In other respects in the situation of identical circuit board, coiling direction (Wickelsinn)
It can be changed by the simple change of the bending die or camber member component of single conductor camber member.By extraly changing conductor
The cross section of part or profile or geometry for example can optimally utilize the space in the inner opening of toroidal cores.In this way, setting
The design scheme for setting the circle section shape of the end conductor section of the inner opening for toroidal cores causes compared to this with round wire rod
Accessible considerably higher packing density.Substitution is mechanically fixed device, for fixation of the wire rod in toroidal cores internal holes and
Plastic castings (Kunststoffverguss) or bonding agent (Klebstoff) also can be used in guidance.
The take-up force needed for firmer wire rod needs the higher strong of core jacket (such as slot (Trog)) to be used
Pressure should be output at soft magnetic core by degree, the core jacket as few as possible.This needs bigger wall thickness and/or stronger material
Material, this generally leads to bigger and more expensive structural detail.It can be obviously reduced by camber member described above in winding
The power of appearance and thus to obtain volume and cost advantage.It can be by melting by the jacket that opaque, nonmagnetic material is constituted
Plastic powders, be for example made of thermoplastic or thermosetting plastics or have such plastics.For jacket
It immerses or spray method may also be combined with epoxy resin, japanning etc. and obtain using this provides insulating layer and/or fixing layer relative to slot
Lesser volume.
Although the main choke coil for considering current compensation, the understanding presented herein are fitted in a manner of same or similar above
For all types of induction structure elements with magnetic annular core.
