按，一般的線圈結構，依其用途差異，通常會具有不同之名稱，例如用來儲能的電感、可抑制高頻雜訊的扼流圈(choke)以及作為變壓器的繞組(winding)等等，請參閱第一圖所示為一種習用的線圈結構，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，此種習用的線圈結構在繞線時，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。 According to the general coil structure, depending on its application, it usually has different names, such as an inductor for energy storage, a choke for suppressing high-frequency noise, and a winding for a transformer. Please refer to the first figure for a conventional coil structure, 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 columnar 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 The electrode 121, the second electrode 122 and the third electrode 123 are disposed in the same direction in sequence with the fourth electrode 131, the fifth electrode 132 and the sixth electrode 133, and the first coil 21 The start end 211 and the end end 212 are respectively connected to the first electrode 121 and the fifth electrode 132. The start end 221 and the end end 222 of the second coil 22 are respectively connected to the second electrode 122 and the sixth electrode 133. The first end 231 and the end end 232 are respectively connected to the first electrode 121 and the fourth electrode 131, and the fourth coil 24 The starting end 241 and the end 242 are respectively connected to the third electrode 123 and the sixth electrode 133. In addition, please refer to the second figure as shown in the second figure. When the winding structure of the conventional coil is wound, the first coil 21 and the first coil are used first. Two coils such as the two coils 22 are wound around the columnar portion 11 of the drum core 10 to form a coil located in the inner layer, and then two coils such as the third coil 23 and the fourth coil 24 are formed. Set for the group A coil 21 and a periphery of the second coil 22 form a coil at the outer layer.

請參閱第一圖與第二圖所示，前述習用的線圈結構其第一線圈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。 Referring to the first and second figures, the conventional coil structure has a starting end 211 of the first coil 21 and a starting end 231 of the third coil 23 connected to the first electrode 121, and the third coil 23 is connected. After the first coil 21 is wound, the winding is started. Therefore, when the starting end 231 of the third coil 23 and the first electrode 121 are to be thermocompression bonded, at this time, since the first electrode 121 has been The initial end 211 of the pressure-bonded first coil 21 still has a certain thickness, which may adversely affect the pressure welding force of the hot pressing device, and easily lead to the combination between the starting end 231 of the third coil 23 and the first electrode 121. The strength is insufficient. In this case, please refer to the third figure. When the winding device rotates the drum core 10 for winding, the tension formed on the coil is easy to make the starting end 231 of the third coil 23 The separation of the first electrode 121 causes de-soldering, thereby reducing the yield of the process or the product. Therefore, how to improve the above-mentioned defects is the technical difficulty to be solved by the applicant of the present application.

有鑑於習用的線圈結構，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電感結構。 In view of the conventional coil structure, 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 Out of the terminal electrode, reducing product yield and reliability, the purpose of this creation is to develop an inductive structure that avoids or reduces the separation of the coil from the terminal electrode.
