However, by this manner of prior art, since the winding segment 12 is wound by starting from the inner side, that is the junction of the first lead 11 and the winding segment 12, some of the available winding space is occupied by the diameter of the first lead 11 itself. For example, at least a width space of the first lead's diameter is occupied. If an angle of the first lead 11 extending out from the winding is large, width space of more than one diameter of the first lead 11 will be occupied.
Therefore, there is a need to provide an improved coil winding.
In accordance with an aspect of the present invention, there is provided a coil winding. The coil winding includes a coil. The coil has a first winding segment and a second winding segment. The first winding segment includes a first lead. The second winding segment includes a second lead. The first winding segment is arranged from an outer concentric of the coil to an inner concentric of the coil along an inward direction as a first winding portion, and the first lead is connected with the first winding portion. The second winding segment is arranged along lateral direction as a second winding portion, overlapping on the second winding portion along an opposite lateral direction as a third winding portion, and further arranged overlapping on the third winding portion along the lateral direction as a fourth winding portion, and the second lead is connected with the fourth winding portion.
In accordance with another aspect of the present invention, there is provided a coil winding. The coil winding includes a coil. The coil has a first winding segment and a second winding segment. The first winding segment includes a first lead. The second winding segment includes a second lead. The first winding segment is stacked along a first direction as a first winding portion, and the first lead is connected with the first winding portion. The second winding segment is arranged along a second direction as a second winding portion, further arranged along a third direction as a third winding portion, and further arranged along the second direction as a fourth winding portion, and wherein the second, third and fourth winding portions are stacked, and the second lead is connected with the fourth winding portion.
In accordance with a further aspect of the present invention, there is provided a coil winding. The coil winding includes a coil. The coil has a first winding segment and a second winding segment. The first winding segment includes a first lead. The second winding segment includes a second lead. The first winding segment is stacked along a direction as a first winding portion, and the first lead is connected with the first winding portion. The second winding segment is sequentially arranged as a plurality of winding portions stacked with each other, and the second lead is connected with the last one of the winding portions.
The present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.
Please refer to
In some embodiments, the length of the second winding segment 22 is preferably greater than the length of the first winding segment 21, and the winding height of the first winding portion 212 is preferably equal to the sum of the winding heights of the second winding portion 222, the third winding portion 223 and the fourth winding portion 224, but are not limited herein.
In an embodiment, when the coil winding 2 of the present invention substantially includes a coil 20 including a total of twenty-four turns of windings that includes three layers and eight turns per layer, the number of turns of the first winding portion 212 is three (i.e. stacked with three turns to form the first winding portion 212). The numbers of turns of the second winding portion 222, the third winding portion 223 and the fourth winding portion 224 are identical. For example, in this embodiment, the number of turns of the second winding portion 222 is seven, the number of turns of the third winding portion 223 is seven, and the number of turns of the fourth winding portion 224 is seven.
In some embodiments, if considering the first winding portion 212 as the inner side, the second winding segment 22 is substantially wound starting from the inner side to the outer side to form a layer of the second winding portion 222, then overlapping a layer by winding from the outer side to the inner side to form a layer of the third winding portion 223, and then overlapping another layer by winding from the inner side to the outer side to form a layer of the fourth winding portion 224. It is envisaged that the winding steps can be implemented in an automatic manner.
As well as the stack and the lateral/horizontal arrangement described in the embodiments mentioned above, other embodiments of the present invention are envisaged as follows. A coil winding 2 of the present invention includes a coil 20. The coil 20 has a first winding segment 21 and a second winding segment 22. The first winding segment 21 includes a first lead 211. Shown in
In some embodiments, the first direction d1 is perpendicular to the second direction d2, the first direction d1 is perpendicular to the third direction d3, and the second direction d2 is parallel to and opposite to the third direction d3. Referring to
Referring to
It should be noted that although the vertical direction described herein is for corresponding with the vertical direction shown in the figures, however it should not be limited when the coil winding 2 of the present invention is practically applied to a magnetic assembly.
By stacking the first winding segment along a vertical direction as a first winding portion and connecting the first lead with the first winding portion, the space where the first lead located at can be directly and sufficiently used, and no extra space is occupied, hence the space can be effectively utilized. Since the first lead is connected with the first winding portion of the first segment, and the second lead is connected with the last one of the winding portions of the second segment, the winding spaces are sufficiently utilized by the two leads of the coil, and thus the problem of occupying more than one diameter of the coil can be avoided.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
