Description
本發明係提供一種具導電膠成型的線圈導體之電感元件，尤指絕緣膠座之複數U形板上為設有導電膠所固化成型之導體，並於絕緣膠座內安裝有導磁元件，且各導體為與連接載體上之線路陣列電性連接，搭配導磁元件形成磁感效應之線圈迴路。 The invention provides an inductance component of a coil conductor with a conductive adhesive, in particular, a plurality of U-shaped plates of the insulating rubber seat are formed by a conductive adhesive, and a magnetic conductive component is installed in the insulating rubber seat. And each of the conductors is electrically connected to the line array on the connection carrier, and the magnetic circuit is combined with the magnetic conductive element to form a coil circuit with a magnetic induction effect.
按，隨著電子技術快速成長，使得電子產品內部之電路板上皆會使用到主動元件與被動元件，其中主動元件(如微處理器或晶片等)可單獨執行運算、處理功能，而被動元件(如電阻、電容與電感等)相對於主動元件則是在進行電流或電壓改變時，可使電阻或阻抗不會隨之改變的元件，並在使用時亦必須考慮各元件之間的電路特性，以相互搭配應用於資訊、通訊、消費電子等，達成電子迴路控制之功能。 According to the rapid growth of electronic technology, active components and passive components are used on the circuit boards inside electronic products. Active components (such as microprocessors or chips) can perform arithmetic and processing functions separately, while passive components. (such as resistors, capacitors, inductors, etc.) relative to the active components, the components that can change the resistance or impedance when the current or voltage changes, and must also consider the circuit characteristics between the components. To match the information, communication, consumer electronics, etc., to achieve the function of electronic loop control.
再者，電感元件會因電路中通過電流的改變產生電動勢，從而抵抗電流的改變，電感元件有多種型式，其中常作為電磁鐵和變壓器中使用的電感依外觀稱為線圈，可對高頻提供較大的電阻，而通過直流或低頻使用的則依功用常稱為扼流圈或抗流圈，並常配合鐵磁性材料來安裝在變壓器、電動機和發電機中所使用的較大電感，亦稱為繞組，且電感元件依電磁感應也可分為自感應和互感應，當纏繞磁性體(如磁芯或鐵磁性 材料)的導線匝數增多時，導體的電感也會變大，不僅是匝數、每匝(環路)的面積等，連導線材料都會影響到電感大小。 Furthermore, the inductive component generates an electromotive force due to the change of the current passing through the circuit, thereby resisting the change of the current. The inductive component has various types, and the inductor used in the electromagnet and the transformer is often referred to as a coil according to the appearance, and can be provided for the high frequency. Larger resistance, while used by DC or low frequency, is often referred to as a choke or choke, and is often used with ferromagnetic materials to install larger inductors used in transformers, motors, and generators. It is called winding, and the inductance component can also be divided into self-induction and mutual induction according to electromagnetic induction, when winding magnetic body (such as magnetic core or ferromagnetic) When the number of wires of the material increases, the inductance of the conductor also becomes large, not only the number of turns, the area of each turn (loop), etc., but the wire material affects the inductance.
而一般電感元件為由鐵磁性之磁芯或比空氣磁導率高的芯材所製成，並於芯材外部纏繞有一環形線圈，便可藉由芯材配合線圈通過電流時產生的磁通量變化，並利用變動的磁場感應誘發出電流，惟該電感元件於實際應用時，仍存在有以下諸多缺失： In general, the inductive component is made of a ferromagnetic core or a core material having a higher magnetic permeability than the air, and a loop coil is wound around the core material to change the magnetic flux generated when the core material is engaged with the coil. And using a variable magnetic field induction to induce current, but in the actual application of the inductance component, there are still many defects:
(1)當電感元件之芯材外部纏繞線圈時，由於人工纏繞手法及方向的不同，常會因繞線分佈上的差異造成線圈疏密不均的情況，並使電感元件上的雜散電容將難以控制，導致相同規格的線圈之間雜訊抑制能力的差異增大，而必須準確的控制線圈繞線彼此間之間距，且因芯材體積較小，採用人工繞線方式不僅整體工序相當耗費工時，亦無法因應製程的需求大量生產，使製造成本也無法降低。 (1) When the core of the inductor element is wound around the core, due to the different manual winding methods and directions, the unevenness of the coil is often caused by the difference in the distribution of the winding, and the stray capacitance on the inductor element will be It is difficult to control, which leads to an increase in the difference in noise suppression capability between coils of the same specification, and it is necessary to accurately control the distance between the coil windings, and because the core material is small in volume, the manual winding method is not only labor-intensive. At the same time, it is impossible to mass-produce according to the requirements of the process, so that the manufacturing cost cannot be reduced.
(2)電感元件為求得較大的電感量，一般會將線圈繞線進行重疊，所以在人工繞線過程中很容易刮傷漆包線的絕緣層，而芯材外部纏繞線圈後，亦會造成芯材體積變大，並將佔用其焊固於電路板上較大的空間而影響到整體電路佈局，而電感元件焊接的過程中，也容易因體積較大與其他電子元件碰觸，導致線圈可能產生刮傷的現象，進而影響到電感元件電氣特性和充放電功能。 (2) Inductive components are used to obtain a large inductance, which generally overlaps the coil windings. Therefore, it is easy to scratch the insulating layer of the enameled wire during the manual winding process, and the core material is wound around the outer coil. The volume of the core material becomes large, and it occupies a large space welded to the circuit board, which affects the overall circuit layout. In the process of soldering the inductor component, it is also easy to touch the other electronic components due to the large volume, resulting in the coil. Scratches may occur, which in turn affects the electrical characteristics of the inductive components and the charge and discharge functions.
是以，習用電感元件纏繞線圈的方式，無論是在整體結構及製程上所衍生之問題都必須予以改善，並因應生產線治具與製程的需求大量生產，使生產效率提高而降低成本，即為從事此行業者所亟欲研究改善之關鍵所在。 Therefore, the way in which the inductive component is wound around the coil, the problems derived from the overall structure and the process must be improved, and the mass production is required in response to the requirements of the production line jig and the process, so that the production efficiency is improved and the cost is reduced. The key to the research and improvement of those who work in this industry.
故，發明人有鑑於上述之習用電感元件很容易因線圈相鄰間距之差異而影響產品的電氣特性，繞線工序複雜所導致生產效率較差及耗費工時與成本之問題與缺失，乃搜集相關資料經由多方的評估及考量，並利用從事於此行業之多年研發經驗不斷試作與修改，始有此種具導電膠成型的線圈導體之電感元件的發明誕生。 Therefore, the inventors have in view of the above-mentioned conventional inductive components that are susceptible to the electrical characteristics of the product due to the difference in the adjacent pitch of the coils. The complicated winding process leads to poor production efficiency and labor and cost. The data was evaluated and evaluated by various parties, and the inventions of the coil conductors with conductive adhesives were born.

續將絕緣膠座1倒置，使其定位部12之U形板121分別向下抵靠於轉印部412上對應互補狀之凸軌4121，並由複數U形板121來將凸軌4121表面上之導電膠130沾起後，使導電膠130分別轉印至U形板121表面上，同時藉由分隔槽122分別具有一預定間距W使各二相鄰U形板121上之導電膠130不會相互沾黏，以有效控制U形板121上未固化(如黏稠狀或膏狀)之導電膠130彼此分隔形成一安全距離，或者是可進一步利用刮板伸入至分隔槽122內將殘膠刮除而不會相互接觸，再將絕緣膠座1為由底模41處移出取下，並於導電膠130在經由烘烤或紫外光固化的過程後，可使導電膠130在複數U形板121表面上分別成型出彼此隔開一距離之導體13，且各導體13二側處分別形成有先向上再外水平延伸之引腳131，便可藉由各二相鄰U形板121間所形成之分隔槽122具有一預定間距W結構設計， 有效防止導電膠130轉印至U形板121上時產生相互沾黏，並使導電膠130固化後彼此之間可分隔形成一安全距離，以精準的控制複數導體13成型的方向及密度，不但可消除導體13相鄰間距之差異，亦可確保絕緣膠座1設置於連接載體3上時，導體13分別焊接於線路陣列32上對應之接點組321形成連續捲繞式之線圈迴路的完整性，進而達到提升產品良率與可靠度、低成本及提高產品一致性之效用。 The insulating rubber seat 1 is continuously inverted, so that the U-shaped plates 121 of the positioning portion 12 respectively abut against the corresponding complementary convex rails 4121 on the transfer portion 412, and the surface of the convex rails 4111 is covered by the plurality of U-shaped plates 121. After the conductive adhesive 130 is smeared, the conductive paste 130 is transferred onto the surface of the U-shaped plate 121, and the conductive paste 130 on each of the two adjacent U-shaped plates 121 is separated by a predetermined spacing W. They are not adhered to each other, so as to effectively control the uncured (e.g., viscous or paste) conductive paste 130 on the U-shaped plate 121 to form a safe distance from each other, or to further extend into the partitioning groove 122 by using the squeegee. The residual glue is scraped off and does not contact each other, and then the insulating rubber seat 1 is removed from the bottom mold 41, and after the conductive adhesive 130 is cured by baking or ultraviolet light, the conductive adhesive 130 can be made in plural. The conductors 13 are formed on the surface of the U-shaped plate 121 at a distance from each other, and the leads 131 of the conductors 13 are respectively formed on the two sides of the first and second horizontally extending pins 131, respectively, by two adjacent U-shaped plates. The partitioning grooves 122 formed by 121 have a predetermined spacing W structural design. The conductive adhesive 130 is effectively prevented from being adhered to each other when being transferred onto the U-shaped plate 121, and the conductive adhesive 130 is solidified and separated to form a safe distance therebetween, so as to accurately control the direction and density of the formation of the plurality of conductors 13, not only the direction and density of the plurality of conductors 13 are precisely controlled. The difference between the adjacent pitches of the conductors 13 can be eliminated, and when the insulating rubber seats 1 are disposed on the connection carrier 3, the conductors 13 are respectively soldered to the corresponding contact groups 321 on the line array 32 to form a complete winding coil circuit. Sexuality, which in turn achieves the benefits of improved product yield and reliability, low cost and improved product consistency.
