第2(甲）圖係用以實施本發明之收納電端子片用托板 (以下，簡稱作「端子用托板」）1〇的立體圖。端子用托板10 宜以通常之銅板或青銅板製作為佳。第2(乙）圖係第2(甲）圖 之A-A線部分剖面圖。端子用托板10的上面係隨著必要而凹 版加工成矩形體狀之2個1組（1對）的端子片收納溝11、11。 在第2(甲）、（乙）圖所顯示之範例中，端子用托板10的上面 於長寬各設有4組(4對）端子片收納溝11，整體排列有16組 (16對)端子片收納溝11。各端子片收納溝11的規格，亦即各 端子片收納溝11的長X寬X高係受最終製品的規格所影響， 而非無差別地規定者。又，2個1組的端子片收納溝11、11 間之間隔，亦受後述之空心線圈等之最終製品的規格所影 響。更進一步，在第2(曱）、（乙）圖所顯示之範例中，包含2 個1組的端子片收納溝11、11之平面雖然為正方形狀，但這 並非本發明之必需要件，可隨著要求之製品的形態而不 同。又，符號12係表示使用在與後述之排列空心線圈用托 板進行緊固之緊固銷孔。 端子用托板10實際上係安裝在通常之振動板（未圖示） 201042676 上而使用。亦即，使端子用托板10在預定之既存的振動事 置上適切地結合後，作動前述振動裝置，在端子用托板10 的表面上供給適當量之預定規格之電端子片13，藉由振動 作用’使各電端子片13自動地收納、排列於端子用托板1〇 之各端子片收納溝11。電端子片13宜以鍍錫之磷青銅板製 作為佳。雖然電端子片13的規格大體上是對應端子片收納 溝11的規格，但是如第2(丙）圖所示，在本發明之實施，電 端子片13的厚度宜較端子片收納溝11的深度稍微厚，以自 端子用托板10的表面稍微突出。電端子片13的厚度雖然宜 為端子片收納溝11的深度之約1.1~1.2倍，但並非是必須 者，亦可適切地變更。當全部的端子片收納溝丨丨皆收納電 端子片13後’以適切的方式將多餘的電端子片自端子用托 板10的表面去除。這與例如在銀行，為了簡單地計算硬幣 的數量而使用設置有該尺寸的硬幣收納溝之計數板的原理 類似。（以上稱作「第1步驟」。） 為了加熱，端子用托板10以通常的方式與通常之適切 的電加熱機構(參考第4圖之符號10’，例如最大可加熱至約 280°C〜300°C之電熱器）結合。對該技術領域之具有通常知 識者而言，如此之與電熱器的結合可有各式各樣的選擇， 故在此省略其具體的構成例。 第3(甲）圖係用以實施本發明之排列空心線圈用托板 (以下，簡稱作「線圈用托板」）20的立體圖。線圈用托板2〇 亦宜以與端子用托板1〇相同之材料(銅板或青銅板）製作為 佳。第3(乙）圖係第3(甲）圖之B-B線部分剖面圖。如第3(曱）、 7 201042676 (乙）圖所示’線圈用托板20的表面設有收納後述之空心線圈 23之圓筒狀的線圈投入孔21。線圈投入孔21的大小（直徑、 深度等)係受使用之空心線圈23的規格所影響。各線圈投入 孔21係設置在與前述第2(甲）、（乙）圖之2個1組的端子片收 納溝11、11的位置分別以1:1正確地對應之位置。又，符號 22係顯示與設置在端子用托板10之緊固銷孔12對應之緊固 銷。 線圈用托板20亦與端子用托板10相同，係與通常的振 動裝置（未圖示）結合而使用。亦即’使線圈用托板2〇與振動 裝置結合後，作動前述振動裝置，在線圈用托板2〇的表面 上才又入適當數量之空心線圈23 ’藉由振動，使各空心線圈 23自動地投入、排列於各線圈投入孔21。多餘的空心線圈 23係以適切的方式而自線圈用托板1〇的表面去除。如第 3(乙）圖所示，線圈投入孔21具有可自由收納空心線圈23的 深度，該入口之左右設置有分別支撑線圈引線23a(23b)、 23b(23a)之線圈引線支撐溝21a(21b)、21b(21a)。如第3(丙） 圖所示，各線圈引線支撐溝21a、21b的深度係線圈引線 23a、23b自線圈用托板20的表面稍微突出之深度，且受使 用之線圈的規格所影響。第3(丙）圖概略地顯示了空心線圈 23投入、排列至線圈投入孔21的狀態之剖面。（以上稱作「第 2步驟」。） 在此，如第3(丙）圖之S所示，空心線圈23之各線圈引線 23a、23b的上面事先進行了適切之預定厚度的焊料接合。 如上述，電端子片13分別收納、排列於端子用托板1〇 201042676 之各端子片收納溝i，空心線圈23分別投入、排列於空心線 ' 圈用托板20之各線圈投入孔21，如第4圖所示，藉由在端子 用托板10之各緊固銷孔12插入線圈用托板20之緊固銷22而 鎖緊’可使線圈用托板20整合於端子用托板10。（以上稱作 「第3步驟」。） 在前述第3步驟中，如先前所述，藉由與端子用托板1〇 結合之電加熱機構10’而傳達熱，各電端子片13係加熱至預 0 定的溫度。在此，加熱溫度宜為焊料熔融溫度以上，亦即 約280°C〜300°C為佳，加熱時間在前述溫度範圍則約秒 為佳。如此’藉由傳達至端子用托板1〇之端子片收納溝^ 所收納之電端子片13的熱，由於焊料s接合於接觸電端子片 13之線圈用托板20之空心線圈23之線圈引線23a、23b，熱 會傳達至焊料S而炫融之，各電端子片π會分別熔接於線圈 引線23a、23b。接著，當端子用托板10及線圈用托板2〇冷 卻’且去除端子用托板10後，在維持於線圈用托板2〇之線 〇 圈投入孔21内之線圈-端子片組合件31的端子背面貼上接 著紙30,使線圈-端子片組合件31自線圈用托板2〇分離。（以 上稱作「第4步驟」。） 以如此方式分離之貼著於接著紙3〇狀態之個別的線圈 -端子片組合件31如第5圖所示。接著，例如，如第5圖所示， 沿著一點鏈線P-P及Q-Q切除接著紙30的邊緣部以準備下一 步驟。（亦可對應需求而省略邊緣部的切斷。） 如第6(甲）圖所示，貼著於接著紙30之線圈_端子片組合 件31係在已貼著於接著紙3〇的情形下放入適切之成形用模 9 201042676 62。又，符號63係可裝卸模a之脫模用基部。接著，如第 6(乙）圖所示，於模62之中空部以既存之方式加入預定量之 金屬磁性粉末而形成金屬磁性粉末層66，藉由加壓裝置P 施加預疋之壓力以加壓成形後進行脫模，藉此，可獲得包 含16個(=4x4)複合電感器之成形件67。第6(丙）圖及第6(丁) 圖分別為前述獲得之成形件67的模式抑圖及模式底面 圖。（以上稱作「第5步驟」。） 為了從成形件67獲得個別之複合電感器^，例如，沿 著在第6(T)圖以-點鎖線顯示之長方向及寬方向之各切斷 線，以適切之切斷方法將成形件67切斷、分離。（以上稱作 「第6步驟」。） 本實施型悲獲得之結果為一次形成合計16個個別的複 合電感Ha。業經切斷、分離之丨個複合電感器α的例擴大 顯示在第6(丁）圖的兩點鎖線圓内。 如前述所不，可對應使用之電或電子裝置所要求之各 種規格而改變最終之複合電感器α之規格與形狀，因此， 對該技術領域之具有通常知識者而言，很明顯地，亦可改 變端子用托板10及線圈用托板20的設計形態。又，在本發 明之方法中，前述第1歩驟與前述第2步驟的順序亦可改變。 以上雖然係舉在1次成形作業中可獲得包含合計16個 (=4x4)複合電感器之成形件的例來說明，但本發明並非限定 於此，依據本發明之方法，隨著需要，在丨次成形作業中至 少可獲得包含2個預定規格之複合電感器的成形件，多則可 獲得包含數十~數百個預定規格之複合電感器的成形件。例 201042676 如’在長寬分別設置10對端子片收納溝11與10個線圈投入 孔21時’可一次獲得100個(=10x10)複合電感器。 因此’依據本發明，藉由以下步驟，可大量形成均一 品質之複合電感器：第1步驟，使收納電端子片用托板在振 動裝置上振動，前述收納電端子片用托板係於表面設置複 數個業經凹版加工以與預定之電端子片形狀一致之2個1組 (1對）之電端子片收納溝η，且於背面以通常方法連結任意 之通常電加熱機構10,者，藉此，使投入至收納電端子片用

[Effects of the Invention] 5 201042676 Compared with the conventional method of forming a composite inductor which is formed by hand work and which is generally of a non-uniform quality, as in the present invention, the following effects can be obtained: a simple one-time production A large number of quality improvements are achieved into a uniform composite inductor. [Embodiment] 1 [Best Mode for Carrying Out the Invention] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The second (a) diagram is a perspective view of a pallet for accommodating an electrical terminal piece of the present invention (hereinafter, simply referred to as a "terminal pallet"). It is preferable that the terminal pallet 10 is made of a usual copper plate or a bronze plate. The second (B) diagram is a partial cross-sectional view taken along line A-A of the second (A) diagram. The upper surface of the terminal pallet 10 is formed into two rectangular (one pair) terminal piece housing grooves 11, 11 in a rectangular shape as necessary. In the example shown in the second (A) and (B) drawings, the upper surface of the terminal pallet 10 is provided with four sets (four pairs) of terminal piece receiving grooves 11 in the length and width, and 16 groups (16 pairs) are arranged in total. The terminal piece accommodation groove 11 is provided. The specifications of the terminal piece accommodation grooves 11, that is, the length X width X of each of the terminal piece accommodation grooves 11 are affected by the specifications of the final product, and are not defined indiscriminately. Further, the interval between the terminal pieces accommodating grooves 11 and 11 of the two sets is also affected by the specifications of the final product such as the air-core coil to be described later. Further, in the example shown in the second (曱) and (B) diagrams, the planes of the terminal sheet accommodation grooves 11 and 11 including the two sets are square, but this is not a necessary part of the present invention. It varies with the form of the desired product. Further, reference numeral 12 denotes a fastening pin hole for fastening to a carrier for arranging the air-core coils to be described later. The terminal pallet 10 is actually used by being mounted on a normal diaphragm (not shown) 201042676. In other words, the terminal pad 10 is appropriately coupled after the predetermined vibration is placed, and the vibrating device is actuated to supply an appropriate amount of the predetermined terminal electrical terminal piece 13 on the surface of the terminal pad 10, Each of the electrical terminal pieces 13 is automatically housed and arranged in the terminal piece accommodation grooves 11 of the terminal pallet 1 by the vibration action. The electric terminal piece 13 is preferably made of a tin-plated phosphor bronze plate. Although the specification of the electrical terminal piece 13 is substantially corresponding to the specification of the terminal piece accommodation groove 11, as shown in the second (c) diagram, in the practice of the present invention, the thickness of the electrical terminal piece 13 is preferably smaller than that of the terminal piece accommodation groove 11. The depth is slightly thicker to protrude slightly from the surface of the terminal pallet 10. The thickness of the terminal piece 13 is preferably about 1.1 to 1.2 times the depth of the terminal piece receiving groove 11, but it is not essential and can be appropriately changed. When all of the terminal piece housing grooves are accommodated in the terminal piece 13, the excess electric terminal piece is removed from the surface of the terminal pad 10 in an appropriate manner. This is similar to the principle of using a counting plate provided with a coin receiving groove of this size, for example, in a bank, in order to simply calculate the number of coins. (The above is referred to as "the first step".) For heating, the terminal pallet 10 is in a usual manner and generally suitable for the electric heating mechanism (refer to the symbol 10' of Fig. 4, for example, it can be heated up to about 280 ° C at the maximum. ~300 °C electric heater) combined. As a person of ordinary skill in the art, there are various options for such a combination with an electric heater, and thus a specific configuration example is omitted here. Fig. 3(a) is a perspective view showing a pallet for arranging an air-core coil according to the present invention (hereinafter, simply referred to as a "coil pallet"). It is preferable that the coil pallet 2 is preferably made of the same material (copper plate or bronze plate) as the terminal pallet 1〇. Figure 3(b) is a partial cross-sectional view taken along line B-B of the third (A) diagram. As shown in Fig. 3 (曱), 7 201042676 (b), the surface of the coil pallet 20 is provided with a cylindrical coil insertion hole 21 for accommodating the air-core coil 23 to be described later. The size (diameter, depth, and the like) of the coil insertion hole 21 is affected by the specifications of the air-core coil 23 to be used. Each of the coil insertion holes 21 is provided at a position corresponding to 1:1 of the positions of the terminal piece receiving grooves 11 and 11 of the two sets of the second (A) and (B) drawings, respectively. Further, reference numeral 22 denotes a fastening pin corresponding to the fastening pin hole 12 provided in the terminal pallet 10. The coil pallet 20 is also used in the same manner as the terminal pallet 10, and is used in combination with a normal vibration device (not shown). That is, after the coil tray 2 is combined with the vibrating device, the vibrating device is actuated, and an appropriate number of air-core coils 23' are inserted into the surface of the coil pallet 2' by the vibration to make the air-core coils 23 The coil insertion holes 21 are automatically placed and arranged. The excess air-core coils 23 are removed from the surface of the coil pallet 1 in a suitable manner.
