Description

用於脈衝濾波器的變壓器Transformer for pulse filter

本創作係有關於一種用於脈衝濾波器的變壓器,尤其是利用包含頂部段、中間段以及底部端的初級側端子及次級側端子配置於基座,並藉位於基座內中間段的轉折段,防止頂部段不會太靠近鐵芯而保持最佳間距以方便初級側線圈、次級側線圈電氣連接至相對應的頂部段,改善焊接,並大幅降低高頻阻抗。The present invention relates to a transformer for a pulse filter, in particular, a primary side terminal and a secondary side terminal including a top section, an intermediate section and a bottom end are arranged on the base, and the turning section is located in the middle section of the base. The top section is prevented from being placed too close to the core to maintain an optimum spacing to facilitate the electrical connection of the primary side coil and the secondary side coil to the corresponding top section, improving soldering and substantially reducing high frequency impedance.

在網路脈衝變壓器中,一般是需要功率電感器當作主線圈使用,而功率電感器的理想特性是耐電流能力越大越好,尤其在微型化尺寸下,可藉提高耐電流能力而降低漏磁,改善整體電氣操作效率。In the network pulse transformer, the power inductor is generally required to be used as the main coil, and the ideal characteristic of the power inductor is that the greater the current withstand capability, the better, especially in the miniaturized size, the leakage resistance can be improved by increasing the current withstand capability. Magnetic to improve overall electrical operation efficiency.

以具微型化尺寸特性的貼片變壓器為例,連接用的端子是由本體的外側向外延伸出去,所以端子在本體的外側,使得整體的體積是包含本體與端子,會較占用印刷電路板(PCB)的空間。例如,本體為10mm,而端子為3mm時,整個片變壓器就是13mm,加上線圈的引出端需要朝向端子而往外且往下延伸,導致引出部分較長,而且焊接也較費時、費力。Taking a chip transformer with miniaturization characteristics as an example, the terminal for connection is extended outward from the outside of the body, so the terminal is on the outer side of the body, so that the overall volume includes the body and the terminal, which will occupy the printed circuit board. (PCB) space. For example, when the body is 10 mm and the terminal is 3 mm, the entire transformer is 13 mm, and the leading end of the coil needs to extend outward and downward toward the terminal, resulting in a long lead-out portion, and the welding is time consuming and laborious.

因此,非常需要一種創新的用於脈衝濾波器的變壓器,利用包含頂部段、中間段以及底部端的初級側端子及次級側端子配置於基座,並藉位於基座內中間段的轉折段以防止頂部段不會太靠近鐵芯而保持最佳間距,能方便初級側線圈、次級側線圈電氣連接至相對應的頂部段,進而改善焊接處理,並能大幅降低高頻阻抗,藉以解決上述習用技術的所有問題。Therefore, there is a great need for an innovative transformer for a pulse filter that is configured on the base by a primary side terminal and a secondary side terminal including a top section, a middle section, and a bottom end, and is borrowed from a turning section of the intermediate section in the base. Preventing the top section from being too close to the core to maintain an optimal spacing, which facilitates the electrical connection of the primary side coil and the secondary side coil to the corresponding top section, thereby improving the soldering process and greatly reducing the high frequency impedance, thereby solving the above All the problems of the conventional technology.

本創作之主要目的在於提供一種用於脈衝濾波器的變壓器,包括基座、鐵芯、初級側線圈、次級側線圈、二初級側端子以及至少二次級側端子,其中基座具電氣絕緣性,並包含凹槽,而鐵芯是黏固於底座的凹槽上。鐵芯具有二中空管道,而且每個中空管道在鐵芯的二端面具有出口孔,並由初級側線圈及次級側線圈繞設該等中空管道。The main purpose of the present invention is to provide a transformer for a pulse filter, comprising a base, a core, a primary side coil, a secondary side coil, two primary side terminals, and at least a secondary side terminal, wherein the base is electrically insulated Sex, and contains grooves, and the core is adhered to the groove of the base. The iron core has two hollow pipes, and each hollow pipe has an outlet hole at two end faces of the iron core, and the hollow pipes are wound by the primary side coil and the secondary side coil.

進一步,每個初級側端子及次級側端子為類似L形,且都包含依序連接的頂部段、中間段以及底部端,中間段是位於基座內,而頂部段、底部端是裸露於基座外,其中頂部段是靠近中空管道的出口孔,尤其,位於基座內的中間段具有轉折段,而底部端是藉轉折段朝向鐵芯而位於基座的底部表面。整體而言,所有的初級側端子及所有的次級側端子都是配置成不超出基座的邊緣,亦即,初級側端子及次級側端子不會增加基座的外觀尺寸大小,可減少占用空間,有利於需要輕、薄、短、小特性的應用領域。Further, each of the primary side terminal and the secondary side terminal are L-shaped, and both include a top section, a middle section and a bottom end which are sequentially connected, the middle section is located in the base, and the top section and the bottom end are bare Outside the base, the top section is an exit aperture adjacent the hollow duct, and in particular, the intermediate section in the base has a turning section and the bottom end is located on the bottom surface of the base by the turning section towards the core. In general, all of the primary side terminals and all of the secondary side terminals are arranged so as not to extend beyond the edge of the base, that is, the primary side terminal and the secondary side terminal do not increase the size of the base, and can be reduced. Taking up space is beneficial to applications that require light, thin, short, and small features.

此外,初級側線圈及次級側線圈是分別電氣連接至初級側端子及次級側端子的頂部段,而初級側端子及次級側端子的底部段係用以電氣連接至印刷電路板(PCB)的電氣線路,比如以表面黏著的方式。Further, the primary side coil and the secondary side coil are respectively electrically connected to the top side of the primary side terminal and the secondary side terminal, and the bottom side sections of the primary side terminal and the secondary side terminal are electrically connected to the printed circuit board (PCB) Electrical wiring, such as by way of surface adhesion.

由於轉折段,所以頂部段不會太靠近鐵芯,能保持最佳的間距,方便底部端對準PCB的接點,容易焊接,不會輕易脫落。此外,轉折段還可降低高頻阻抗,改善電氣品質。再者,初級側線圈、次級側線圈的大部分是在繞設在中空管道的內部,所以能大幅降低漏磁,提高電氣訊號強度。Due to the turning section, the top section is not too close to the core, and the optimum spacing can be maintained, so that the bottom end is aligned with the joint of the PCB, which is easy to solder and does not fall off easily. In addition, the turning section also reduces high frequency impedance and improves electrical quality. Furthermore, most of the primary side coil and the secondary side coil are wound inside the hollow duct, so that the magnetic flux leakage can be greatly reduced and the electric signal strength can be improved.

本案特點在於端子有頂段與底端是外露的,中間段是在基座裡並具有轉折段,端子整體不超出基座之邊緣,因此可減少占用空間。另外,水平的中空管道剛好讓線圈的引出端對應且靠近端子,容易連接極易於焊接,不容易脫落。再者,端子具有轉折段,可使端子的頂部不會太靠近鐵芯,因而端子底部仍可剛好對應於PCB的接點。The present invention is characterized in that the terminal has a top section and a bottom end which are exposed, the middle section is in the base and has a turning section, and the whole terminal does not exceed the edge of the base, thereby reducing the occupied space. In addition, the horizontal hollow pipe just makes the lead end of the coil correspond to and close to the terminal, and the connection is easy to be welded, and it is not easy to fall off. Furthermore, the terminal has a turning section so that the top of the terminal does not come too close to the core, so that the bottom of the terminal can still correspond exactly to the contact of the PCB.

尤其,端子的轉折段可用有效降低高頻阻抗,因為高頻線路佈局的任何不連續性都嚴重影電氣傳輸特性,而銳角轉折即會增加每單位長度的電容,且每單位長度的電感會減少。因此,本創作特別設計出轉折段,藉以解決上述問題。In particular, the turning section of the terminal can effectively reduce the high frequency impedance, because any discontinuity of the high frequency line layout seriously affects the electrical transmission characteristics, while the acute angle turning increases the capacitance per unit length and the inductance per unit length is reduced. . Therefore, this creation specifically designed a turning section to solve the above problems.

以下配合圖示及元件符號對本創作之實施方式做更詳細的說明,俾使熟習該項技藝者在研讀本說明書後能據以實施。The implementation of the present invention will be described in more detail below with reference to the drawings and component symbols, so that those skilled in the art can implement the present specification after studying the present specification.

具體而言,底座10具電氣絕緣性,並包含凹槽11,而鐵芯20是卡合於底座的凹槽11。此外,鐵芯20具有相互分離的二中空管道21,而且每個中空管道21在鐵芯20的二端面分別具有出口孔22,並由初級側線圈50及次級側線圈60繞設該等中空管道21,且相互間並不電氣連接。Specifically, the base 10 is electrically insulating and includes a recess 11 and the core 20 is a recess 11 that is engaged with the base. In addition, the iron core 20 has two hollow pipes 21 separated from each other, and each hollow pipe 21 has an outlet hole 22 at each end surface of the iron core 20, and the hollow is wound by the primary side coil 50 and the secondary side coil 60. The pipes 21 are not electrically connected to each other.

每個初級側端子50及次級側端子60為具有類似L形的外觀,並包含依序連接或一體成型的頂部段、中間段以及底部端,且初級側線圈50及次級側線圈60是分別電氣連接至初級側端子50及次級側端子的頂部段。以次級側端子60為例,次級側端子60是包含頂部段61、中間段62以及底部端63,且中間段62是位於基座10內,而頂部段61、底部端63是裸露於基座10外,其中頂部段61是靠近中空管道21的出口孔22。此外,底部端63是以正L型的90度角連接中間段62,並朝向鐵芯20而位於基座10的底部表面。Each of the primary side terminal 50 and the secondary side terminal 60 has an L-like appearance and includes a top section, a middle section, and a bottom end which are sequentially connected or integrally formed, and the primary side coil 50 and the secondary side coil 60 are They are electrically connected to the top sections of the primary side terminal 50 and the secondary side terminal, respectively. Taking the secondary side terminal 60 as an example, the secondary side terminal 60 includes a top section 61, a middle section 62, and a bottom end 63, and the intermediate section 62 is located in the base 10, while the top section 61 and the bottom end 63 are bare. Outside the base 10, the top section 61 is an exit aperture 22 adjacent the hollow conduit 21. Further, the bottom end 63 is joined to the intermediate section 62 at a 90 degree angle of a positive L-shape and is located on the bottom surface of the base 10 toward the core 20.

進一步而言,底部端63是可藉焊接方式而電氣連接印刷電路板(PCB)70的電氣線路71,比如表面黏著技術(SMT)。Further, the bottom end 63 is an electrical line 71 that can be electrically connected to a printed circuit board (PCB) 70 by soldering, such as surface mount technology (SMT).

整體而言,所有的初級側端子50及所有的次級側端子60都是配置成不超出基座10的邊緣,且頂部段61的部分也不超過鐵芯20的頂面,其中鐵芯20的頂面是相對於鐵芯20被黏合於基板的一面,亦即,初級側端子50及次級側端子60不會增加基座11的整體外觀尺寸大小,因而可減少占用空間,有利於需要輕、薄、短、小特性的應用領域。In general, all of the primary side terminals 50 and all of the secondary side terminals 60 are configured not to extend beyond the edge of the base 10, and the portion of the top section 61 does not exceed the top surface of the core 20, wherein the core 20 The top surface of the core 20 is bonded to the substrate with respect to the core 20, that is, the primary side terminal 50 and the secondary side terminal 60 do not increase the overall size of the base 11, thereby reducing the space occupied and facilitating the need. Light, thin, short, and small features.

進一步參考第二圖,本創作第二實施例用於脈衝濾波器的變壓器的示意圖。如第二圖所示,本創作的第二實施例是類似於第一實施例,也同樣包含基座10、鐵芯20、初級側線圈30、次級側線圈40、二初級側端子50以及至少二次級側端子60,而其間的主要差異在於第二實施例的變壓器是在基座11內的中間段62特別設置成具有轉折段62A,而且底部端63是藉轉折段62A朝向鐵芯20而位於基座10的底部表面。With further reference to the second figure, a second embodiment of the present invention is a schematic diagram of a transformer for a pulse filter. As shown in the second figure, the second embodiment of the present invention is similar to the first embodiment, and also includes a susceptor 10, a core 20, a primary side coil 30, a secondary side coil 40, two primary side terminals 50, and At least the secondary side terminal 60, and the main difference therebetween is that the transformer of the second embodiment is disposed in the intermediate section 62 in the base 11 to have a turning section 62A, and the bottom end 63 is oriented toward the core by the turning section 62A. 20 is located on the bottom surface of the base 10.

尤其,第二實施例的轉折段62A實質上是包含至少二彎折角,圖中只顯示二彎折角的示範性實例,而且每個彎折角的範圍是較佳的在30~60度之間,用以提供降低高頻阻抗的功能,尤其是最佳的45度,因而達成中間段62至且底部端63的整體轉彎為90度角,係有別於第一實施例的中間段62是藉單一的90度角彎折而轉到底部端63的方向。進一步而言,第二實施例的具體功效是可減緩電氣線路佈局的不連續性,減少每單位長度的電容,並增加每單位長度的電感,進而有效降低高頻阻抗,改善電氣信號的傳輸品質。In particular, the turning section 62A of the second embodiment substantially includes at least two bending angles, and only an exemplary example of two bending angles is shown, and the range of each bending angle is preferably between 30 and 60 degrees. The function of reducing the high frequency impedance, especially the optimum 45 degrees, thus achieving the intermediate turn 62 and the overall turn of the bottom end 63 is a 90 degree angle, which is different from the middle section 62 of the first embodiment. A single 90 degree angle bends to the direction of the bottom end 63. Further, the specific effect of the second embodiment is to slow down the discontinuity of the electrical circuit layout, reduce the capacitance per unit length, and increase the inductance per unit length, thereby effectively reducing the high frequency impedance and improving the transmission quality of the electrical signal. .

綜上所述,本創作的特點在於利用包含頂部段、中間段以及底部端的初級側端子及次級側端子配置於基座,並藉位於基座內中間段的轉折段,防止頂部段不會太靠近鐵芯而保持最佳間距以方便底部端對準PCB的接點,並改善焊接而將初級側線圈、次級側線圈電氣連接至相對應的頂部段,同時水平的中空管道剛好能讓線圈的引出端對應且靠近端子,所以很容易焊接而不會輕易脫落。再者,端子整體不超出基座之邊緣,因而可減少所占用的空間,改善PCB的使用效率。In summary, the present invention is characterized in that the primary side terminal and the secondary side terminal including the top section, the middle section and the bottom end are arranged on the base, and the turning section of the middle section in the base is prevented, so that the top section is not prevented. Too close to the core to maintain the optimal spacing to facilitate the bottom end to align the PCB contacts, and to improve the soldering to electrically connect the primary side coil and the secondary side coil to the corresponding top section, while the horizontal hollow duct just allows The leading end of the coil corresponds to and is close to the terminal, so it is easy to solder without falling off easily.
