工業發展持續進步，然而各式電路基本元件，如電感之發展卻 受到製程技術之限制，造成其效能遲遲無法突破。如第1圖所示， 習知電感總成1，係由一導磁芯11與線圈12所構成。其中，線圈 12纏繞並容置於導磁芯11所構成之一容置空間内，因此導磁芯 11之容置空間越大及容置空間内部高度越大，線圈12之導線截面 積適可越大。線圈12之導線截面積越大，則電感總成1之直流阻 抗（Direct Current Resistance ; DCR)可降至越低。因此，此產業無 不驥望線圈12之導線截面積可持續加大，使電感總成1之直流阻 抗值可降低，藉此避免習知電感總成1所輸入的電能耗損在直流 阻所產成之熱能。然而，習知電感總成1之線圈12係使用習知之 圓形截面導線，且線圈12於導磁芯11内纏繞之空間，實質上係 被導磁芯11之高度所限制，故線圈12之截面積無法任意擴展， 進而限制直流阻抗值降低之極限。 因此，此產業之供應商無不盡力提高導磁芯11内部容置空間之 高度，以降低直流阻抗，然而其中仍存在製造上之瓶頸。當導磁 芯11於製造過程中，必須先將呈顆粒狀之原材料填充進入一模具 内，再施加一相當程度之外力壓擠填充材料，以使顆粒中間缝隙 被高壓壓縮，使導磁芯體積減小並且更為結實。更進一步地來說， M361107 若高度過高及深寬比過大，將使得導磁芯11内顆粒分佈不均勻， 造成所完成之導磁芯11末端具有鑄造成形缺陷及成分粒子濃度不 均之嚴重問題，進而造成導磁芯11密度不均勻、導磁特性不穩定、 易碎，更甚者成為瑕疵品無法使用等各項嚴重問題。 承上所述，習知電感總成1之導磁芯u囿於製造上之實際困 難，其内部空間之高度限制仍然無法突破。因而，目前仍只能製 造出較低深寬比之導磁芯u，實質限制線圈12纏繞於導磁芯n 之纏繞空間，隨之線圈12之截面積便無法提高，更無法降低直流 阻抗。 有鑑於此，提供一種低直流阻抗之電感總成，為此技術領域所 亟需解決之目標。 【新型内容】 本創作之目的在於提供一種電感總成，係利用二導磁部分之相 應接合以提升導磁㈣寬比達—倍，制Μ平之導線纏繞形成 線圈，以增加截面積’藉此達到降低直流阻抗之目的。 為1¾工地 A D ό —守碗芯以及— 該導磁m Ε字形之導磁部分。該等導㈣分各具有^ 支臂m支臂具有-軸向。該等 报成一a窣弗社接 1刀適以相對應接合 4 +〜構。猎此，相對於習知電感總成，本創作 芯具有更大之線圈容置空間、更大之深寬比、 W： , Ar ^ A- Ρϊ "^線圈具有一導 讀’該W讀具有—寬度方向垂直㈣ 繞於該等導磁部分之該等中I φ 11，並/σβ亥轴向 刀茨寺中央支臂上，以形成誃始萌甘心 導電帶條更包含-體成形之二引腳，該^ ° /、， X、腳係位於導電帶條 M361107 二末端，經一厚度薄化之後得以彎折至該等導磁部分之一底板， 並設置於該底板之二卡槽中，俾該等引腳適可接合於一印刷電路 板上。相對於習知線圈，在相同之導線厚度上，本創作之線圈具 有較大之截面積。藉此，本創作之電感總成達到大幅降低直流阻 抗之目的。 為讓上述目的、技術特徵及優點能更明顯易懂，下文係以較佳 之實施例配合所附圖式進行詳細說明。Industrial development continues to improve. However, the development of basic components of various circuits, such as inductors, is limited by process technology, resulting in delays in its performance. As shown in Fig. 1, the conventional inductor assembly 1 is composed of a magnetic core 11 and a coil 12. The coil 12 is wound and accommodated in one of the accommodating spaces formed by the magnetic core 11. Therefore, the larger the accommodating space of the magnetic core 11 and the higher the internal height of the accommodating space, the cross-sectional area of the coil 12 is suitable. The bigger. The larger the cross-sectional area of the coil 12, the lower the direct current resistance (DCR) of the inductor assembly 1 can be reduced. Therefore, the industry can only hope that the cross-sectional area of the coil 12 can be continuously increased, so that the DC resistance value of the inductor assembly 1 can be reduced, thereby avoiding the electrical energy loss input by the conventional inductor assembly 1 in the DC resistance. Into the heat. However, the coil 12 of the conventional inductor assembly 1 uses a conventional circular section wire, and the space in which the coil 12 is wound in the core 11 is substantially limited by the height of the core 11, so the coil 12 The cross-sectional area cannot be arbitrarily expanded, thereby limiting the limit of the DC resistance value reduction. Therefore, suppliers in this industry have tried their best to increase the height of the internal space of the magnetic core 11 to reduce the DC resistance, but there are still manufacturing bottlenecks. When the magnetic conductive core 11 is in the manufacturing process, the raw material in the form of particles must be first filled into a mold, and a relatively large force is applied to squeeze the filling material so that the intermediate gap of the particles is compressed by high pressure, so that the volume of the magnetic core is compressed. Reduced and more robust. Furthermore, if the height of the M361107 is too high and the aspect ratio is too large, the particle distribution in the magnetic core 11 will be uneven, resulting in the formation of the forming core defect and the uneven concentration of the constituent particles. The problem is that the density of the magnetic core 11 is not uniform, the magnetic permeability is unstable, and it is fragile, and even more serious problems such as the inability to use the product. As described above, the magnetic core of the conventional inductor assembly 1 is practically difficult to manufacture, and the height limitation of the internal space cannot be broken. Therefore, at present, only the magnetic core u having a low aspect ratio can be manufactured, and the coil 12 is substantially confined around the winding space of the magnetic core n, so that the cross-sectional area of the coil 12 cannot be increased, and the DC impedance cannot be lowered. In view of this, it is an object of the art to provide an inductor assembly with low DC impedance. [New content] The purpose of this creation is to provide an inductor assembly that utilizes the corresponding joints of the two magnetically conductive portions to increase the magnetic permeability (four) width ratio by a factor of -1, and the winding of the wire to form a coil to increase the cross-sectional area. This achieves the goal of reducing DC impedance. It is a 13⁄4 site A D ό — the bowl core and — the magnetically conductive m Ε shaped magnetic part. The guides (four) each have an arm arm that has an axial direction.

Compared to conventional coils, the coil of the present invention has a larger cross-sectional area at the same wire thickness. In this way, the inductor assembly of the present invention achieves the purpose of greatly reducing the DC resistance. The above objects, technical features and advantages will be more apparent from the following description.

The magnetic core 21 includes two E-shaped magnetic conductive portions 211, and the two E-shaped magnetic conductive portions 211 are two independent elements from each other before being combined. Each of the magnetic conductive portions 211 has a central arm 211a, and the central arm 211a has an axial direction, and the two E-shaped magnetic conductive portions 211 are adapted to be joined to each other to form a day-shaped structure. Thereby, the height of the internal space of the inductor assembly 2 can be doubled. The coil 22 has a conductive strip 221 comprising a flat copper wire and an insulating varnish film wrapped around the copper wire. Among them, the conductive strip 221 has a width direction perpendicular to the axial direction. It should be noted here that the width of the conductive strip 221 itself in the width direction is greater than the thickness in the axial direction. The conductive strip 221 is wound on the central arm 211a of the magnetic conductive portion 211 in the axial direction perpendicular to the axial direction to form the coil 22. Thereby, the same or larger coil wire cross-sectional area can be obtained at the same or smaller wire thickness to improve the internal space utilization of the inductor assembly 2. With the design of the magnetic core 21 and the coil 22 of the present invention, the DC resistance of the inductor assembly 2 of the present invention can be greatly reduced. If the DC inductance of the inductor assembly 2 is larger than that of the conventional inductor assembly 1, the size of the inductor assembly 2 M361107 is larger and the internal space is more efficient, so that the size can be made smaller. Please refer to FIG. 4 and FIG. 5, which depict the magnetic conductive portion 211 of the E-shape of the present invention at different angles. The artificial magnetic conductive portion 211 further includes a bottom plate 211b and two side walls 211c. The bottom plate 211b, the two side walls 211c, and the central arm 211a collectively constitute an E-shaped structure of the magnetic conductive portion 211. In the preferred embodiment, the two side walls 211c and the bottom plate 211b are further extended to form a shield as shown. When the two magnetic conductive portions 211 are joined to each other, the inductor assembly 2 can shield the external electromagnetic interference by the shield. Thereby, the inductor assembly 2 can have a stable inductance effect. The shielding cover of the magnetic core 21 surrounds an accommodating space for accommodating the coil 22, and the shielding cover of each magnetic conductive portion 211 forms two notches 21 If, when the two shielding portions of the two magnetic guiding portions 211 are engaged with each other, The corresponding combination is a two-pin hole 23 for the two pins 222 of the conductive strip 221 to pass through. As shown in Fig. 5, the bottom plate 211c of one of the magnetic conductive portions 211 further includes a second card slot 211d and an outer bottom surface 211e. The card slots 21 Id are formed on opposite sides of the outer bottom surface 21 le . The two card slots 211d are adapted to respectively receive two pins 222 formed by one of the conductive strips 221. The lead 222 located at the end of the strip 221 is subjected to a thickness thinning process, and is bent and disposed in the second card slot 211d of the bottom plate 211c. The pin 222 is adapted to be bonded to a printed circuit board. . Please refer to FIG. 3 and FIG. 6 in combination, wherein the two pins 222 included in the conductive strip 221 are the two end segments of the conductive strip 221 . In the preferred embodiment, the two pins 222 pass through the two-pin holes 23, are bent and partially disposed in the two card slots 221d, so that the inductor assembly 2 of the present invention is suitable for directly bonding to a circuit board (not shown). One of the surfaces is shown, and it is not necessary to pierce the lead holes in the circuit, that is, the inductor assembly 2 M361107 of the present invention is a Surface Mounted Device (SMD). In other implementations, the pins 222 are not allowed to be placed in the card slot, and are not bonded to the circuit board by using different bonding modes. Furthermore, the magnetically conductive portions 211 of the two E-shapes may not extend to form a mask, and the heights thereof may be unequal. Variations of such equivalence are within the scope of the claims claimed herein. ^ The above-mentioned only examples are only used to illustrate the implementation of this creation, and to explain the creative features of this creation, which is not intended to limit the protection of this creation.
