Description
本新型創作是有關於一種磁性組件,且特別是有關於一種薄型化的磁性組件。 The present invention relates to a magnetic component, and in particular, to a thinned magnetic component.
現今的電子產品經常使用各式的磁性組件,例如變壓器、電感元件等,以藉由電磁感應原理滿足所需的電路設計。現有的磁性元件是利用在二個磁芯的中心柱之間形成的單一氣隙,來避免磁飽和。然而,單一氣隙若間距過大,則會造成較高的磁損,而導致能量耗損增加。再者,目前具氣隙的磁性元件需使用繞線組,其中線圈繞設於繞線架,而繞線架固定於二個磁芯之間,因而無法有效地達到輕薄化。為了因應電器設備的薄型化,磁性元件及內部使用的繞線組亦須朝薄型化的趨勢發展,以降低電器設備的整體體積。因此,如何在提高效率且降低的磁損及漏電感的同時,還能薄型化磁性組件,已成為本領域亟需解決的問題之一。 Today's electronic products often use various magnetic components, such as transformers, inductance components, etc., to meet the required circuit design by the principle of electromagnetic induction. Existing magnetic components use a single air gap formed between the central legs of the two magnetic cores to avoid magnetic saturation. However, if the single air gap is too large, it will cause higher magnetic loss, resulting in increased energy loss. Furthermore, the current magnetic element with an air gap needs to use a winding set, wherein the coil is wound on the winding frame, and the winding frame is fixed between the two magnetic cores, so it cannot effectively achieve thinning. In order to cope with the thinning of electrical equipment, the magnetic components and windings used inside must also develop toward thinning, so as to reduce the overall volume of electrical equipment. Therefore, how to reduce the magnetic loss and leakage inductance while improving the efficiency and reducing the thickness of the magnetic component has become one of the urgent problems to be solved in the art.

一般來說,由於氣隙漏磁的磁通在磁芯橫截面上相當於以氣隙的間隙為直邊的半圓形或弓形,因此隨著氣隙高度的增加,漏磁磁通的橫截面積呈平方倍數增加,對於實際的立體空間來說是呈立方倍數增加。因此,本實施例透過多個柱體140a來形成單一間距的多個氣隙A1,除了可防止磁飽和的效果外,亦可大大降低與分散漏磁耗損,降低擴散磁通,而使磁性組件100a具有低漏電感與低磁損,進而提高工作效率。
Generally speaking, since the magnetic flux of the air-gap leakage magnetic flux is equivalent to a semicircle or an arcuate shape with the gap of the air gap as a straight side on the cross section of the magnetic core, as the height of the air gap increases, the horizontal leakage magnetic flux The cross-sectional area increases in square multiples, and for the actual three-dimensional space, it increases in cubic multiples. Therefore, in this embodiment, multiple air gaps A1 with a single pitch are formed through

考圖1B與圖3A,本實施例的磁性組件200a與上述實施例的磁性組件100a相似,兩者的差異在於:本實施例的第一磁芯210a與第二磁芯220a皆分別呈現一凹槽狀,且柱體包括多個第一柱體242a與多個第二柱體244a。詳細來說,請同時參考圖3A與圖3B,每一電路板230具有彼此分離的多個貫孔232,且電路板230的貫孔232彼此對應設置。第一磁芯210a與第二磁芯220a相互組裝而定義出內部空間S2,而對應堆疊在一起的電路板230、第一柱體242a以及第二柱體244a皆位於內容空間S2中。電路板230的連接孔234位於第一磁芯210a與第二磁芯220a外,且連接件250分別對應穿過連接孔234,而使電路板230可與外部電路電性連接。更進一步來說,在本實施例中,第一柱體242a配置於第一磁芯210a上,且第一柱體242a與第一磁芯210a一體成形。第二柱體244a配置於第二磁芯220a上,且第二柱體244a與第二磁芯220a一體成形。第一柱體242a的數量對應於第二柱體244a的數量,且第一柱體242a對應第二柱體244a而形成相同間距的氣隙B1。因此,本實施例的磁性組件200a具有高效率、薄型化、易組裝、製程生產效率高、低磁損及低漏感等優勢。

磁芯220b上,且第二柱體244b與第二磁芯220b為各自獨立的構件。第一柱體242b對應第二柱體244b而形成相同間距的氣隙B2。

第二氣隙B62的間距。也就是說,本實施例透過第一柱體242f、第二柱體244f來形成不同間距的第一氣隙B61與第二氣隙B62,除了可防止磁飽和的效果外,亦可使磁性組件200f具有高效率、薄型化、易組裝、製程生產效率高、低磁損及低漏感等優勢。

綜上所述,在本新型創作的磁性組件的設計中,多個柱體會分別對應穿過電路板的貫孔,而在柱體彼此之間或柱體與第一磁芯及第二磁芯至少其中一者之間形成多個氣隙。藉此,可提高本新型創作的磁性組件的工作效率,而具有高效率、低磁損及低漏感的優勢。此外,透過彼此堆疊的電路板來取代現有的繞線組,可達到薄型化的效果,而使本新型創作的磁性組件滿足現今對電器設備的薄型化需求。 To sum up, in the design of the magnetic component created by the present invention, a plurality of cylinders respectively correspond to the through holes passing through the circuit board, and between the cylinders or between the cylinders and the first magnetic core and the second magnetic core A plurality of air gaps are formed between at least one of them.
