本創作係有關於一種變壓器結構。 This creation is about a transformer structure.
請參閱第一圖所示為一種習用的變壓器，其係由一鼓型鐵芯10、一第一線圈21、一第二線圈22、第三線圈23以及一第四線圈24所構成，其中，該鼓型鐵芯10包括位於中間的柱狀部11與連接於柱狀部11兩端的第一法蘭12及第二法蘭13，該第一法蘭12上依序設有第一電極121、第二電極122與第三電極123，該第二法蘭13以相同的方向順序依序設有第四電極131、第五電極132與第六電極133，該第一線圈21的起始端211與末端212分別連接該第一電極121與第五電極132，該第二線圈22的起始端221與末端222分別連接該第二電極122與第六電極133，該第三線圈23的起始端231與末端232分別連接該第一電極121與第四電極131，該第四線圈24的起始端241與末端242分別連接該第三電極123與第六電極133，此外，請再配合參閱第二圖所示，此種習用的變壓器在繞線時，係先以第一線圈21及第二線圈22等兩條線圈為一組繞設在該鼓型鐵芯10的柱狀部11上，形成位於內層的線圈，然後，再以第三線圈23及第四線圈24等兩條線圈為一組繞設在該第一線圈21與第二線圈22的外圍，形成位於外層的線圈。 Referring to the first figure, a conventional transformer is constructed, which is composed of a drum core 10, a first coil 21, a second coil 22, a third coil 23, and a fourth coil 24. The drum core 10 includes a cylindrical portion 11 in the middle and a first flange 12 and a second flange 13 connected to the two ends of the column portion 11. The first flange 12 is sequentially provided with a first electrode 121. The second electrode 122 and the third electrode 123 are sequentially provided with the fourth electrode 131, the fifth electrode 132 and the sixth electrode 133 in the same direction, and the starting end 211 of the first coil 21 The first electrode 121 and the fifth electrode 132 are respectively connected to the end 212. The start end 221 and the end 222 of the second coil 22 are respectively connected to the second electrode 122 and the sixth electrode 133, and the start end 231 of the third coil 23 The first electrode 121 and the fourth electrode 131 are respectively connected to the end 232. The start end 241 and the end 242 of the fourth coil 24 are connected to the third electrode 123 and the sixth electrode 133, respectively. As shown in the figure, when the conventional transformer is wound, the first coil 21 and the second coil 22 are first used. The coil is wound around a column portion 11 of the drum core 10 to form a coil located in the inner layer, and then wound around the two coils such as the third coil 23 and the fourth coil 24 The first coil 21 and the outer periphery of the second coil 22 form a coil on the outer layer.
請參閱第一圖與第二圖所示，前述習用的變壓器其第一線圈 21的起始端211與第三線圈23的起始端231均連接到該第一電極121，且第三線圈23係於第一線圈21繞設完畢後才開始繞設，因而，當第三線圈23的起始端231與第一電極121兩者欲進行熱壓焊接結合時，此時，由於第一電極121上已壓焊好的第一線圈21之起始端211仍具有一定厚度，故會對熱壓設備的壓焊力道造成負面影響，容易導致第三線圈23的起始端231與第一電極121之間的結合強度不足，如此一來，請再配合參閱第三圖所示，當繞線設備轉動該鼓型鐵芯10進行繞線時，其對線圈形成的張力易使第三線圈23的起始端231與第一電極121分離，造成脫焊，進而降低製程或產品的良率，是故，如何針對上述缺失加以改進，即為本案申請人所欲解決之技術困難點所在。 Please refer to the first figure and the second figure, the first coil of the aforementioned conventional transformer The start end 211 of the 21 and the start end 231 of the third coil 23 are both connected to the first electrode 121, and the third coil 23 is wound after the first coil 21 is wound, and thus, when the third coil 23 is When both the starting end 231 and the first electrode 121 are to be subjected to thermocompression bonding, at this time, since the initial end 211 of the first electrode 21 that has been pressure-welded on the first electrode 121 still has a certain thickness, it will be hot. The pressure welding force of the pressing device has a negative influence, which easily causes the bonding strength between the starting end 231 of the third coil 23 and the first electrode 121 to be insufficient. Therefore, please refer to the third figure as shown in the third figure. When the drum core 10 is rotated to perform winding, the tension formed on the coil easily separates the starting end 231 of the third coil 23 from the first electrode 121, causing de-soldering, thereby reducing the yield of the process or the product. How to improve the above-mentioned deficiencies, that is, the technical difficulties that the applicant of this case wants to solve.
有鑑於習用的變壓器，其不同組線圈的繞線起始端共同連接到鼓型鐵芯的同一個端電極，造成後繞的線圈其起始端與端電極之間的焊接強度不足，甚至導致線圈脫離端電極，降低產品良率與可靠度，因此本創作之目的在於發展一種可避免或減少線圈脫離端電極之變壓器結構。 In view of the conventional transformer, the winding start ends of different sets of coils are commonly connected to the same terminal electrode of the drum core, resulting in insufficient welding strength between the starting end and the end electrode of the wound coil, and even causing the coil to be detached. The terminal electrode reduces product yield and reliability, so the purpose of this creation is to develop a transformer structure that avoids or reduces the coil from the terminal electrode.
為達成以上之目的，本創作係提供一種變壓器結構，其包含一鼓型鐵芯、一第一線圈、一第二線圈、一第三線圈與一第四線圈，其中：該鼓型鐵芯具有一柱狀部以及連接於該柱狀部兩端的第一法蘭與第二法蘭，該第一法蘭上依序設有第一電極、第二電極、第三電極與第四電極，該第二法蘭依序設有第五電極、第六電極與第七電極；該第一線圈的起始端及末端分別與第二電極及第五電極相連接，該第二線圈的起始端及末端分別與第三電極及第六電極相連接，該第三線圈的起始端及末端分別與第一電極及第五電極相連接，該第四線圈的起始端及末端分別與第四電極及 第七電極相連接。 In order to achieve the above object, the present invention provides a transformer structure including a drum core, a first coil, a second coil, a third coil and a fourth coil, wherein: the drum core has a columnar portion and a first flange and a second flange connected to the two ends of the column portion, wherein the first flange is sequentially provided with a first electrode, a second electrode, a third electrode and a fourth electrode, The second flange is sequentially provided with a fifth electrode, a sixth electrode and a seventh electrode; the starting end and the end of the first coil are respectively connected to the second electrode and the fifth electrode, and the starting end and the end of the second coil Connected to the third electrode and the sixth electrode respectively, the start end and the end of the third coil are respectively connected to the first electrode and the fifth electrode, and the start end and the end end of the fourth coil are respectively connected to the fourth electrode and The seventh electrode is connected.
藉此，本創作即可確保後繞的線圈其頭端與鼓型鐵芯的端電極之間的壓焊強度，避免後續繞線時，線圈與端電極之間容易因張力而脫落分離的缺失，進而使本創作可達到大幅提高產品良率與可靠度之功效。 Therefore, the creation can ensure the welding strength between the front end of the coil and the end electrode of the drum core, and avoid the loss of separation between the coil and the end electrode due to tension during subsequent winding. In turn, this creation can achieve a significant increase in product yield and reliability.
