Technical Field

[0001] The present invention relates to an inductor device, and more particularly to a distributed core inductor device in which a strip conductor passes through a core only once. Background Art

[0002] Generally speaking, the inductor device in the market is an electromagnetic induction element. It winds a certain number of turns of coils around a bobbin or a core by repeatedly passing a wire through the copper window of the core to achieve the required inductance.

[0003] However, the above method of manufacturing an inductor device has the following disadvantages. The above wire repeatedly passes through the copper window of the core, so a large length of wire is consumed, the wire resistance and copper loss are increased, and the heat generated by the wire winding and the core is easily accumulated inside the parts, resulting in poor heat dissipation, and the overall shape has less flexibility for the internal space layout of the module.

[0004] It can be seen that the above technology still has obvious inconveniences and defects, which are urgent problems to be solved in this industry. Summary of the Invention

[0006] An embodiment of the present invention provides a distributed core inductor device. The distributed core inductor device includes at least one first strip conductor and a plurality of magnetic cores. The first strip conductor is flexible. These magnetic cores are sequentially fixed on the first strip conductor, and each magnetic core is only passed through by the first strip conductor once.

[0007] According to one or more embodiments of the present invention, in the above distributed core inductor device, each magnetic core has a through channel, the first strip conductor is located in these through channels, and these through channels are respectively only passed through by the first strip conductor once.

[0008] According to one or more embodiments of the present invention, the above distributed core inductor device further includes a transformer and at least one second strip conductor. The second strip conductor sequentially passes through these magnetic cores, is located in these through channels, and is adjacent to the first strip conductor. Each through channel is only passed through by the second strip conductor once. The transformer is respectively connected to the first strip conductor and the second strip conductor.

[0009] According to one or more embodiments of the present invention, in the above-described distributed iron core inductor device, each magnetic core includes an outer side surface, a top, and a bottom. The top and the bottom are opposite to each other, the outer side surface surrounds the top and the bottom, and a through-channel connects the top and the bottom respectively. A part of the first strip conductor continuously passes through the bottoms of two adjacent magnetic cores, another part of the first strip conductor continuously passes through the tops of another two adjacent magnetic cores, a part of the second strip conductor continuously passes through the tops of two adjacent magnetic cores, and is opposite to the part of the first strip conductor, and another part of the second strip conductor continuously passes through the bottoms of another two adjacent magnetic cores, and is opposite to the other part of the first strip conductor.

[0010] According to one or more embodiments of the present invention, in the above-described distributed iron core inductor device, the cross-sectional width of one of the through-channels is the same as the cross-sectional width of the first strip conductor.

[0011] According to one or more embodiments of the present invention, in the above-described distributed iron core inductor device, these magnetic cores are kept separated from each other such that a part of the first strip conductor is exposed between any two adjacent magnetic cores.

[0012] According to one or more embodiments of the present invention, in the above-described distributed iron core inductor device, these magnetic cores can be separably and sequentially directly stacked.

[0013] According to one or more embodiments of the present invention, in the above-described distributed iron core inductor device, the first strip conductor includes a metal wire and an insulating layer, and the insulating layer surrounds and coats the outer surface of the metal wire.

[0014] According to one or more embodiments of the present invention, in the above-described distributed iron core inductor device, each magnetic core includes two C-shaped bodies, and the first strip conductor is clamped by these C-shaped bodies.

[0016] Thus, through the above architecture, the distributed iron core inductor device of the present invention does not require the strip conductor to repeatedly pass through the through-channel of the magnetic core, which not only reduces the length usage, resistance, and copper loss of the strip conductor, but also greatly improves the utilization rate of the through-channel. In addition, the overall surface area of the magnetic core is significantly exposed, and no heat accumulation is caused inside, which helps to improve the overall heat dissipation efficiency.

[0063] Multiple embodiments of the present invention will be disclosed below with reference to the accompanying drawings. For the sake of clarity, many practical details will be described together in the following narrative. However, it should be understood that these practical details should not be used to limit the present invention. That is to say, in one embodiment of the present invention, these practical details are non-essential. In addition, for the purpose of simplifying the drawings, some conventional structures and elements will be shown in a simple schematic manner in the drawings.

[0064] Figure 1ASchematic diagram of a circuit to which a distributed iron core inductor device 10 according to an embodiment of the present invention is applied. In this embodiment, as Figure 1A shown, the distributed iron core inductor device 10 includes a first strip-shaped conductor 100 and a plurality of magnetic cores (or iron cores) 300. The first strip-shaped conductor 100 is flexible, and these magnetic cores 300 are sequentially fixed on the first strip-shaped conductor 100, and each magnetic core 300 is only passed through by the first strip-shaped conductor 100 once. For example, each magnetic core 300 has a through-channel 310. The first strip-shaped conductor 100 is located in these through-channels 310 of these magnetic cores 300, and these through-channels 310 are respectively only passed through by the first strip-shaped conductor 100 once. In other words, among two adjacent magnetic cores 300, after the first strip-shaped conductor 100 extends out of the through-channel 310 of one magnetic core 300, it will directly extend into the through-channel 310 of the other magnetic core 300 and will not wind around the same magnetic core 300.

[0065] More specifically, in this embodiment, these magnetic cores 300 are kept separated from each other, so that the first strip-shaped conductor 100 is partially exposed between any two adjacent magnetic cores 300. Since these separated magnetic cores 300 are connected in series by the first strip-shaped conductor 100, these magnetic cores 300 can be arbitrarily and dispersedly arranged according to the spatial layout inside the product module, greatly improving the configuration flexibility of the component layout.

[0066] In this embodiment, the cross-sectional area of each through-channel 310 is the same as the cross-sectional area of the first strip-shaped conductor 100, or each through-channel 310 and the first strip-shaped conductor 100 have at least the same cross-sectional width 311, so that the first strip-shaped conductor 100 can be fixed in the through-channels 310 of these magnetic cores 300.

[0067] In this embodiment, each magnetic core 300 is integrally formed, and the through-channel 310 is directly formed thereon. However, the present invention is not limited thereto. Although the first strip-shaped conductor 100 is located in the through-channel 310 of the magnetic core 300, in other embodiments, the magnetic core 300 does not have a through-channel 310, that is, each magnetic core 300 may also be directly formed on the first strip-shaped conductor 100, so that the first strip-shaped conductor 100 is fittingly embedded in the magnetic core 300.

[0068] Furthermore, the distributed iron core inductor device 10 further includes a transformer ID and a wire B. More specifically, the transformer ID is electrically connected to the wire B respectively, and the first strip-shaped conductor 100, the transformer ID and the wire B are connected in series in sequence.

[0069] In addition, in this embodiment, Figure 1B Cross-sectional view of the first strip-shaped conductor 100 of this embodiment. As Figure 1BAs shown, the first strip-shaped conductor 100 is a conductive cable, and includes an axially-shaped metal wire 110 and an insulating layer 120. The insulating layer 120 surrounds and covers the outer surface of the metal wire 110. However, the present invention is not limited thereto. In other embodiments, the first strip-shaped conductor may also be a sheet-shaped conductive cable.

[0070] It should be understood that although the inductance generated by the first strip-shaped conductor 100 passing through N magnetic cores 300 once is similar to the inductance generated by a conventional wire winding around a single magnetic core N times, however, the distributed iron core inductance device 10 of this embodiment can not only reduce the length, resistance, and copper loss of the first strip-shaped conductor 100, but also contribute to the improvement of the heat dissipation efficiency due to the large exposure of the overall magnetic core surface area.

[0071] Figure 2A FIG. is an exploded view of a magnetic core 300 according to an embodiment of the present invention. Figure 2B is Figure 2A a combined view of the magnetic core 300 of. The magnetic core 300 of this embodiment is substantially the same as the magnetic core 300 of Figure 1A except that, as shown in Figure 2A and Figure 2B each magnetic core 300 includes a first C-shaped body 320 and a second C-shaped body 330, and the first strip-shaped conductor 100 is clamped by the first C-shaped body 320 and the second C-shaped body 330. More specifically, a first groove 322 is recessed on a side surface 321 of the first C-shaped body 320, and a second groove 332 is recessed on a side surface 331 of the second C-shaped body 330.

[0072] Therefore, when the side surface 321 of the first C-shaped body 320 is in direct contact with the side surface 331 of the second C-shaped body 330, the first groove 322 and the second groove 332 are connected to each other to form the above-mentioned through-channel 310, and the first strip-shaped conductor 100 is clamped in the through-channel 310. In this way, it helps the user to install each magnetic core 300 on the first strip-shaped conductor 100. In addition, each magnetic core 300 can fix the first strip-shaped conductor 100 to the magnetic core 300 through a fixing structure (not shown in the figure) such as a screw or a clamp. However, the present invention is not limited thereto.

[0073] Figure 3 FIG. is a circuit schematic diagram of one application of a distributed iron core inductance device 11 according to an embodiment of the present invention. As shown in Figure 3 the distributed iron core inductance device 11 of this embodiment is substantially the same as the distributed iron core inductance device 10 of Figure 1A except that, as shown in Figure 2A and Figure 2BAs shown, the distributed iron core inductor device 11 further includes a second strip-shaped conductor 200. These magnetic cores 300 are sequentially fixed on the second strip-shaped conductor 200, and the second strip-shaped conductor 200 sequentially passes through these magnetic cores 300, is located within these through-channels 310, and is adjacent to the first strip-shaped conductor 100. In other words, the first strip-shaped conductor 100 and the second strip-shaped conductor 200 are arranged side by side within the through-channels 310 of each magnetic core 300.

[0074] The through-channel 310 of each magnetic core 300 is only passed through by the second strip-shaped conductor 200 once. In other words, among two adjacent magnetic cores 300, after the second strip-shaped conductor 200 extends out of the through-channel 310 of one magnetic core 300, it will directly extend into the through-channel 310 of the other magnetic core 300 and will not wind around the same magnetic core 300 multiple times.

[0075] More specifically, the second strip-shaped conductor 200 is flexible, and the second strip-shaped conductor 200 is electrically connected to the transformer ID. The transformer ID is respectively connected to one end of the first strip-shaped conductor 100 and one end of the second strip-shaped conductor 200.

[0076] In this embodiment, at least the cross-sectional widths 311 of each through-channel 310 are substantially the same as the cross-sectional widths of the first strip-shaped conductor 100 and the second strip-shaped conductor 200 arranged side by side, so that the first strip-shaped conductor 100 and the second strip-shaped conductor 200 are clamped within the through-channels 310 of these magnetic cores 300.

[0077] Figure 4 It is a schematic structural diagram of one application of the distributed iron core inductor device 12 according to an embodiment of the present invention. As Figure 4 shown, the distributed iron core inductor device 12 of this embodiment is substantially the same as Figure 3 the distributed iron core inductor device 11, and the difference is that each magnetic core 340 is annular and includes an outer side surface 341, a top 342, and a bottom 343. The top 342 and the bottom 343 face each other. The outer side surface 341 surrounds the top 342 and the bottom 343, and the through-channels 310 located within the magnetic core 340 are respectively connected to the top 342 and the bottom 343. However, the present invention is not limited to the shape of the magnetic core.

[0078] A part of the first strip-shaped conductor 100 continuously passes through the bottoms 343 of two adjacent magnetic cores 340, another part of the first strip-shaped conductor 100 continuously passes through the tops 342 of another two adjacent magnetic cores 340, a part of the second strip-shaped conductor 200 continuously passes through the tops 342 of two adjacent magnetic cores 340, and is opposite to the said part of the first strip-shaped conductor 100, and another part of the second strip-shaped conductor 200 continuously passes through the bottoms 343 of another two adjacent magnetic cores 340, and is opposite to the said another part of the first strip-shaped conductor 100.

[0079] In this embodiment, more specifically, one or two magnetic cores 340 form a set, and the magnetic cores 340 of each set are directly stacked on top of each other, such that the bottom 343 of one magnetic core (reference numeral 340A) of each set is in direct contact with the top 342 of the other magnetic core (reference numeral 340B). These sets are spaced apart from each other, and the first strip conductor 100 passes through these sets in a wavy pattern, and the second strip conductor 200 passes through these sets in a wavy pattern.

[0080] In this embodiment, the above-mentioned magnetic cores 340 are grouped into a first set A1, a second set A2, a third set A3, and a fourth set A4 that are spaced apart from each other. The first part 130 of the first strip conductor 100 extends from the top 342 of the upper magnetic core 340A of the first set A1 into the first set A1. The second part 140 of the first strip conductor 100 connects to the first part 130, and extends from the bottom 343 of the lower magnetic core 340B of the first set A1 out of the first set A1, and then directly extends into the second set A2 from the bottom 343 of the lower magnetic core 340B of the second set A2. The third part 150 of the first strip conductor 100 connects to the second part 140, and extends from the top 342 of the upper magnetic core 340A of the second set A2 (see the second dashed line, Figure 4 ) out of the second set A2, and then directly extends into the third set A3 from the top 342 of the upper magnetic core 340A of the third set A3 (see the second dashed line, Figure 4 ) The fourth part 160 of the first strip conductor 100 connects to the third part 150, and extends from the bottom 343 of the lower magnetic core 340B of the third set A3 (see the second dashed line, Figure 4 ) out of the third set A3, and then from the bottom 343 of the lower magnetic core 340B of the fourth set A4 (see the second dashed line, Figure 4)It directly extends into the fourth set A4. The fifth part 170 of the first strip conductor 100 is connected to the fourth part 160 and extends out of the fourth set A4 from the top 342 of the upper magnetic core 340A of the fourth set A4. The sixth part 210 of the second strip conductor 200 extends into the fourth set A4 from the bottom 343 of the lower magnetic core 340B of the fourth set A4 and is arranged relative to the fifth part 170 of the first strip conductor 100. The seventh part 220 of the second strip conductor 200 is connected to the sixth part 210 and extends out of the fourth set A4 from the top 342 of the upper magnetic core 340A of the fourth set A4, and then directly extends into the third set A3 from the top 342 of the upper magnetic core 340A of the third set A3 and is arranged relative to the fourth part 160 of the first strip conductor 100. The eighth part 230 of the second strip conductor 200 is connected to the seventh part 220 and extends out of the third set A3 from the bottom 343 of the lower magnetic core 340B of the third set A3, and then directly extends into the second set A2 from the bottom 343 of the lower magnetic core 340B of the second set A2 and is arranged relative to the third part 150 of the first strip conductor 100. The ninth part 240 of the first strip conductor 100 is connected to the eighth part 230 and extends out of the second set A2 from the top 342 of the upper magnetic core 340A of the second set A2, and then directly extends into the first set A1 from the top 342 of the upper magnetic core 340A of the first set A1 and is arranged relative to the second part 140 of the first strip conductor 100. The tenth part 250 of the first strip conductor 100 is connected to the ninth part 240 and extends out of the first set A1 from the bottom 343 of the lower magnetic core 340B of the first set A1 and is arranged relative to the first part 130 of the first strip conductor 100.

[0081] Thus, when the distributed core inductor device 12 is operated and the current direction CR1 of the first strip conductor 100 and the current direction CR2 of the second strip conductor 200 are opposite to each other, the current directions CR1 and CR2 of the first strip conductor 100 and the second strip conductor 200 in the penetration channel 310 of the same magnetic core 340 are the same.

[0082] Figure 5 It is a schematic structural diagram of one application of the distributed core inductor device 13 according to an embodiment of the present invention. As Figure 5 shown, the distributed core inductor device 13 of this embodiment is substantially the same as the Figure 3 distributed core inductor device 12, and the difference is that these magnetic cores 340 can be detachably stacked directly in sequence, and the first strip conductors 100 and the second strip conductors 200 are respectively a plurality of. These first strip conductors 100 are arranged side by side in the penetration channel 310 of each magnetic core 340, these second strip conductors 200 are arranged side by side in the penetration channel 310 of each magnetic core 340, and the first strip conductors 100 and the second strip conductors 200 are in contact with each other or at least quite close.

[0083] Thus, through the above architecture, the distributed iron core inductor device of this case does not need the strip conductor to repeatedly pass through the through-channel of the magnetic core, which not only reduces the length usage, resistance and copper loss of the strip conductor, but also greatly improves the utilization rate of the through-channel. In addition, the surface area of the overall magnetic core is largely exposed, without causing heat accumulation inside it, which helps to improve the overall heat dissipation efficiency.

[0084] Finally, in the above-disclosed embodiments, they are not intended to limit the present invention. Any person skilled in this art can make various changes and modifications without departing from the spirit and scope of the present invention, and all can be protected by the present invention. Therefore, the protection scope of the present invention shall be subject to that defined by the appended claims.
