Description
本發明係有關一種線圈模組,用於例如電感器、變壓器等磁感應元件。 The present invention relates to a coil module used in magnetic induction elements such as inductors and transformers.
例如變壓器等磁感應元件的架構至少包括有兩組獨立的線圈(coil),即所謂的「初級線圈」與「次級線圈」,在通電流後根據電磁感應原理、以該兩組線圈的圈(匝)比進行電壓數值的轉換。 For example, the structure of a magnetic induction element such as a transformer includes at least two independent coils, the so-called "primary coil" and "secondary coil". After the current is applied, the coils of the two sets of coils ( Turns) ratio performs voltage value conversion.
實際的應用上,該變壓器通常會被架構在一獨立的絕緣基座(base)上,該絕緣基座會預先佈署有複數導電針(pin)或接觸腳與線圈相連而形成一變壓器總成,並透過這些導電針或接觸腳與外部的電路焊接相連,使這個變壓器總成與外部電路導通使用,同時以該絕緣基座作為訊號隔離避免發生干 擾。 In practical applications, the transformer is usually constructed on an independent insulating base, which is pre-deployed with a plurality of conductive pins or contact pins connected to the coil to form a transformer assembly , And through these conductive pins or contact pins and the external circuit welding connection, so that the transformer assembly and the external circuit conduction use, at the same time the insulating base as a signal isolation to avoid interference Disturb.
為配合消費型電子產品的小型化需求,這些變壓器的設計越為輕薄是不可避免的趨勢,在已知的先前技術中有使用印刷電路板(PCB)的電路印刷技術製成線圈組,產出一種扁平式(或平板式)變壓器(Planar transformer),例如中國公開第CN201138608號專利說明書所揭露者,就是揭露一種在PCB上印刷有導電線圈圖案的變壓器總成。該項第’608號專利使用PCB製作包括了初級線圈及次級線圈,並在該兩組線圈的表面塗布一層絕緣漆予以隔離,通過與磁芯的組裝成為一種扁平式的變壓器。 In order to meet the miniaturization needs of consumer electronic products, it is inevitable that these transformers are designed to be thinner and lighter. In the known prior art, a printed circuit board (PCB) circuit printing technology is used to make a coil assembly. A flat (or flat) transformer, such as the one disclosed in the Chinese Patent Specification No. CN201138608, discloses a transformer assembly with conductive coil patterns printed on a PCB. The '608 patent uses a PCB to make a primary coil and a secondary coil, and coats the surfaces of the two sets of coils with a layer of insulating paint to isolate them, and is assembled with the magnetic core to form a flat transformer.
第’608號先前技術雖然可以讓變壓器的體積薄形化,但是在製造、組裝的過程中仍存在有不少的缺陷如下: Although the prior art No. 608 can make the volume of the transformer thinner, there are still many defects in the manufacturing and assembly process as follows:
1.須知,利用PCB印刷技術製造導電線圈圖案成為變壓器的初級、和次級線圈的工法複雜,耐電流小,而且成本負擔高,所製成之產品難以在市場上具有價格競爭優勢。 1. It should be noted that the use of PCB printing technology to make conductive coil patterns to become the primary and secondary coils of the transformer has a complicated construction method, low current resistance, and high cost burden. It is difficult for the products made to have a price competitive advantage in the market.
2.在該兩組線圈的表面塗布絕緣漆作為彼此隔離,難以符合變壓器製造的安全規範需求,容易使變壓器在運作中產生損害;特別是用在連接市電的AC-DC變壓器,由於AC電源端的電壓差大,初級線圈和次級線圈之間在規範上更必須具備一定安全間距的隔離。 2. Coating insulating paint on the surface of the two sets of coils as isolation from each other, it is difficult to meet the safety requirements of transformer manufacturing, and it is easy to cause damage to the transformer during operation; especially the AC-DC transformer used to connect to the mains, due to the The voltage difference is large, and the isolation between the primary coil and the secondary coil must have a certain safety distance in the specification.
3.第’608號先前技術中的圖7及圖8所揭露之變壓器中,一組初級線圈(5A)及兩組次級線圈(4A,6A)在與磁芯(M1)進行組裝時,該磁芯(M1)的中央導磁柱必須分別通過每一組線圈上預留的組裝孔,所以這些線圈組裝孔的對位必須非常精準,否則將造成組裝上的困難,或者造成線圈與磁芯之間隙過大的間題。特別是,如該案之圖8所示的兩組由PCB製成的次級線圈(4A,6A)還需要精準地通過左側示意的導電針(pin)使彼此的線圈圖案連通後再提供與外部電路連接使用,更是難以依此設計導入自動化、大量生產的主要因素。 3. In the transformer disclosed in Figures 7 and 8 in the prior art No. '608, one set of primary coils (5A) and two sets of secondary coils (4A, 6A) are assembled with the magnetic core (M1), The central magnetic column of the magnetic core (M1) must pass through the assembly holes reserved on each set of coils, so the alignment of these coil assembly holes must be very precise, otherwise it will cause assembly difficulties, or cause the coil and the magnetic The core gap is too large. In particular, the two sets of secondary coils (4A, 6A) made of PCB as shown in Figure 8 of the case also need to be accurately connected to each other's coil patterns through the conductive pins shown on the left before providing them with The use of external circuit connection is the main factor that is difficult to introduce automation and mass production according to this design.
另一項發明人已知與本發明有關的先前技術,是美國公開第2013/0278371號專利所揭露的一種平面式變壓器,其係將複數個預先製作的平板線圈(包括初級及次級線圈)依順序穿套在變壓器的磁芯上,並提供一已建立有複數導電針(pin)的基座(base),利用焊接技術與該些線圈、以及外部的電路連接,其中,該基座可作為磁芯與外部電路的隔離保護。 Another prior art known to the inventors related to the present invention is a planar transformer disclosed in US Patent No. 2013/0278371, which combines a plurality of pre-made plate coils (including primary and secondary coils) Put it on the magnetic core of the transformer in sequence, and provide a base with a plurality of conductive pins (pins) established, and connect the coils and external circuits by welding technology. The base can be As the isolation protection between the magnetic core and the external circuit.
顯而易見的,該項第’371號先前技術所使用之平板式金屬線圈可以預先透過模鑄、或沖壓直接成型,製造的成本相較於前揭以PCB製成的線圈會低廉許多也更適於量產,而且該金屬層的厚度也相較於PCB印刷導電線圈耐受更大的電流;但是就變壓器製造的程序、以及組裝的過程中依然存在有 以下缺陷: Obviously, the flat metal coil used in the prior art No. '371 can be directly formed by die-casting or stamping in advance, and the manufacturing cost is much lower than that of the previously disclosed coil made of PCB and is more suitable. Mass production, and the thickness of the metal layer can withstand a larger current compared to PCB printed conductive coils; however, there are still some problems in the transformer manufacturing process and assembly process. The following defects:
1.各平板線圈之間缺少了安全間距的隔離設計,如前所述,即使在各組線圈的表面塗布一層絕緣漆作為隔離,亦難以符合變壓器安全規範需求,特別是用於連接市電的AC-DC變壓器,由於電源端的電壓差大,容易使該變壓器在運作中產生損害。 1. There is a lack of isolation design for safe spacing between the flat coils. As mentioned above, even if a layer of insulating paint is applied to the surface of each group of coils as isolation, it is difficult to meet the requirements of transformer safety regulations, especially AC used to connect to the mains -DC transformer, due to the large voltage difference at the power supply terminal, it is easy to cause damage to the transformer during operation.
2.各組線圈皆為一獨立的單元與構件,在與磁芯進行組裝時,磁芯的中央導磁柱必須依序通過每一組線圈上預留的組裝孔,所以這些線圈組裝孔的對位必須非常精準,不僅使組裝的難度提高、容易失敗,而且浪費工時,更難以導入自動化製程而不利於大量的生產作業。 2. Each set of coils is an independent unit and component. When assembling with the magnetic core, the central magnetic pole of the magnetic core must pass through the assembly holes reserved on each set of coils in sequence, so these coil assembly holes The alignment must be very precise, which not only increases the difficulty of assembly and is prone to failure, but also wastes man-hours, making it more difficult to introduce automated processes to the disadvantage of large-scale production operations.
3.該些導電針預先被固定在一獨立的基座(base)上,不論是初級、或次級之各線圈的線端都必須一一連接到各導電針上進行導通,如果線圈數需求較多(此與初級和次極線圈的匝比有關),勢必影響到生產的效能,顯而易見的,連接的次數越多越容易發生錯誤,例如盲接、或錯接,進而造成失敗率的增加。 3. The conductive pins are fixed in advance on an independent base, and the wire ends of the coils of the primary or secondary must be connected to the conductive pins one by one for conduction. If the number of coils is required More (this is related to the turns ratio of the primary and secondary coils), it will inevitably affect the efficiency of production. Obviously, the more the number of connections, the more errors will occur, such as blind connection or wrong connection, which will increase the failure rate. .
為改善先前技術存在的缺陷,本發明提供一種更為新穎的「磁感應線圈模組」,相較於先前技術,不僅更利於製造、組裝,在以此作為電感器、或變壓器等磁感應元件的應用時將更為便利,並可以降低終端產品的不良比率,為本發明之主要目的。 In order to improve the shortcomings of the prior art, the present invention provides a more novel "magnetic induction coil module".

本發明所述之第二組線圈可以利用模鑄、或沖壓導電材料製作以降低生產成本,其中,以所述第一迴圈本體及第二迴圈本體一體連接成為第二組線圈,減化了先前技術使用多個獨立線圈在組裝上的工序,以及必須精準對位的麻煩;特別是,在與外部線路連接時只需要通過所提供的第一導通部及 第二導通部兩個接點對接,減少了可能發生盲接的機會,也更有效地提升了終端產品的可靠度。 The second set of coils of the present invention can be made by die-casting or stamping conductive materials to reduce production costs. Among them, the first loop body and the second loop body are integrally connected to form the second set of coils, which reduces It eliminates the prior art using multiple independent coils in the assembly process and the trouble of precise alignment; in particular, it only needs to pass through the provided first conducting part and The two contacts of the second conducting part are connected, which reduces the chance of blind connection and improves the reliability of terminal products more effectively.
