본 고안은, 예를들면 광대역 증폭기에 사용하는 파이킹코일등의 인덕턴소자에 관한 것이다.The present invention relates to an inductance element such as, for example, a peaking coil for use in a broadband amplifier.
종래, 이 종류의 인덕턴소자는, 예를들면 제1도 및 제2도에 표시함과 같이, 드럼코어(1)의 권장부에 코일(2)을 감음과 동시에 코어(1)의 양측단면에 형성된 원추형상의 요부(3)의 표면에 온도금층(4)을 처리하고, 이 은도금층부분에 코일(2)의 단말(2a)과 리이드신(5)을 납땜하여 고정해서 접속하고, 그 바깥쪽을 절연와장피막(6)으로 피복하도록 구성하고 있는 것이 통상이다. 그러나, 피이킹코일과 같이 비교적 저가격의 전자기기에서, 귀금속과 같이 값비싼 은을 사용할 경우에는 생산비면에서 수지가 맞지않고, 또 은전극의 형성에 그것을 응용한 상태로 사용하지 않으면 안되므로, 필요 이외의 곳에 은이 튕겨서 코일을 더럽히거나, 단락발생원인이 되며, 혹은 Q값이나 자체공전주파수의 산란을 일으킬 원인이 되고 있다.2. Description of the Related Art Conventionally, this kind of inductance element winds the coil 2 around the recommended portion of the drum core 1, as shown in FIG. 1 and FIG. The temperature gold layer 4 is treated on the surface of the concave recessed portion 3 formed in the groove, and the terminal 2a and the leadscene 5 of the coil 2 are fixed by soldering to the silver plated layer portion and connected to the outside. It is common to comprise so that the side may be coat | covered with the insulation coating film 6. However, if expensive silver such as precious metal is used in relatively low-cost electronic devices such as picking coils, the resin is not suitable in terms of production cost and must be used in the state of applying it to the formation of silver electrodes. Silver may bounce off the coils and contaminate the coil, cause a short circuit, or cause scattering of the Q value or its own resonant frequency.
본 고안은, 이러한 결점을 제거하고, 대폭적인 생산비저하를 가능케 함과 동시에 균일한 성능, 품질을 갖도록 구성할 수 있는 인덕턴소자를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide an inductor element that can be configured to eliminate such drawbacks and to allow for a significant reduction in production costs and at the same time to have uniform performance and quality.
즉, 본 고안에 관한 인덕턴소자에 있어서는 은도금충 대신에 구리, 알루미늄등의 금속박을 철심의 양단면에 접착고정하고, 그 금속박위에서 코일의 단말과 리이드단자를 납땜 접속하므로서 구성하고 있다. 이와같이 구성하는 인덕턴소자에서는, 구리박, 알루미늄박등의 금속박이 은등의 귀금속에 비해 저렴하기 때문에 생산비저하를 가능케하고, 또 그것으로 인한 전극층이 박막을 접착하므로서 형성되기 때문에, 작업능률을 향상할 수 있음과 동시에 품질, 성능을 균일하게 구성할 수 있고 또 그 향상도 가능하게 한다. 이하, 이것을 도시한 실시예에 따라서 설명한다.That is, in the inductance element according to the present invention, a metal foil such as copper or aluminum is fixed to both ends of the iron core in place of the silver plating insect, and the solder is connected to the terminal of the coil and the lead terminal on the metal foil. In the inductance element configured in this way, metal foils such as copper foil and aluminum foil are cheaper than precious metals such as silver, thus enabling lower production costs, and the resulting electrode layers are formed by bonding thin films, thereby improving work efficiency. At the same time, the quality and performance can be uniformly configured and the improvement can be made. This will be described below in accordance with the illustrated embodiment.
도시한 인덕턴소자는 피이킹코일등의 소형코일부품이며, 막대 형상의 자심(7) 혹은 드럼자심(7')등 적의 형상의 자심에 코일(8)을 감은 구성을 가진 것이다. 자심(7)(7')의 양측단면에는 구리, 알루미늄등의 도전성을 가진 저렴한 금속박(9)이 각각 접착제(10)에 의해 첩착고정되고, 전극층이 형성되어 있다. 이 전극층을 형성하는 금속박은 시이트형상의 것으로, 광폭시이트를 임의로 형상으로 베어내서 성형하므로서 이용할 수 있다. 또, 그 접합면에는 접착제접합에 의한 경우는 열경화성접착제를 미리 도포해둘 수 있다. 그 도포에 의해, 지그등으로 가열가압해서 금속박을 접착고정할 수 있기 때문에 접합작업을 극히 간단하게 한다. 그 금속박에 대해 코일(8)의 단말(8a)은 리이드선(11)의 축상단과 겹치게 접촉하거나 혹은 얽어 감기 등으로 접합해서, 금속박표면에 당접된다 .당해 당접부는 납땜(12)에 의해 금속박면에 접착고정되고, 리이드단자(11)가 자심(7)(7')의 양측아래쪽에 돌출하도록 위치하고 있다. 그 외주에는 자심(7)(7')의 둘레를 덮는 절연피막(13)이 형성되고, 인덕턴스소자의 완성체로서 구성되어 있다.The inductance element shown is a small coil component such as a picking coil, and has a configuration in which a coil 8 is wound around a magnetic core having an enemy shape, such as a rod-shaped magnetic core 7 or a drum magnetic core 7 '. On both side cross-sections of the magnetic cores 7 and 7 ', inexpensive metal foils 9 having conductivity such as copper and aluminum are attached to each other by the adhesive 10, and an electrode layer is formed. The metal foil which forms this electrode layer is sheet-like, and can be used by shaping | molding a wide sheet arbitrarily in shape. In addition, a thermosetting adhesive can be previously apply | coated to the joining surface by adhesive bonding. Since the application can be performed by pressing with a jig or the like to bond and fix the metal foil, the joining operation is extremely simple. With respect to the metal foil, the terminal 8a of the coil 8 is brought into contact with or overlapped with the axial end of the lead wire 11 by contact with the metal foil surface, and the metal foil surface is brought into contact with the metal foil. Adhesively fixed to the surface, the lead terminal 11 is positioned so as to protrude below both sides of the magnetic cores 7 and 7 '. At its outer periphery, an insulating coating 13 covering the periphery of the magnetic cores 7 and 7 'is formed, and is constituted as a complete body of inductance elements.
또한, 자심의측면에는 제5도에 표시한 바와같이 원형사각형등 적의형상의 요부(4)를 형성하고, 그 요부내에 금속박(9)을 첩착 배치하도록 할수 있다. 적의경우에는 금속박(9)이 밀려나가는 일이없이 자심의 측면 정위치에 간단히 접착할 수 있게되어, 조립작업을 간편하게 할 수 있다.In addition, as shown in FIG. 5, on the side face of the magnetic core, the recessed recessed part 4 of circular shape, such as a circular shape, is formed, and the metal foil 9 can be stuck and arrange | positioned in the recessed part. In the case of the enemy, the metal foil 9 can be easily adhered to the side position of the magnetic core without being pushed out, thereby simplifying the assembly work.
이와같이 구성된 인덕턴소자에서는, 전극층(9)이 구리, 알루미늄등의 저렴한 재료로 구성되어 있으며, 은과같은 고가재료는 일체사용되고 있지않다. 또, 구리, 알루미늄등의 금속재료는 박막체로 해서 접착하므로 전극층(9)을 형성하기 위해서 부착되기 때문에, 은과같은 용융상태로 처리하지 않으면 안될 노력이나 굽기(700℃ ∼ 900℃)가 전혀 불필요하게 되어있다. 또한, 전극층(9)은 미리 소정치수로 성형되기 때문에 손실계수나 자체공진주파수등의 품질, 성능이 특정지어지고 더우기 향상되게 된다. 그 특성변화를 Q값에 따라서 확인한 바, 제6(a)도와 같이 제6(b)도의 은도금 사용예에 비해서 현저하게 향상된 것이 판명되었다.In the inductance element thus constructed, the electrode layer 9 is made of inexpensive materials such as copper and aluminum, and no expensive material such as silver is used at all. In addition, since metal materials such as copper and aluminum are adhered to form a thin film, they are attached to form the electrode layer 9, and thus no effort or baking (700 ° C to 900 ° C) that must be processed in a molten state such as silver is unnecessary. It is supposed to be. In addition, since the electrode layer 9 is molded to a predetermined dimension in advance, the quality and performance of the loss coefficient, the self-resonant frequency, and the like are specified and further improved. The characteristic change was confirmed in accordance with the Q value, and as shown in FIG. 6 (a), it was found to be remarkably improved compared to the silver plating use example of FIG. 6 (b).
이상과 같이, 본 고안에 관한 인덕턴소자에 의하면, 조립작업을 간소화하고 더우기 굽는 에너지의 절약도 가능하게 하여 제품을 값싸게 하고, 또한 소정의 특성을 갖게해서 품질, 특성의 향상을 도모할 수 있게되므로, 이상적인 소자의 제공이 가능하게 된다.As described above, according to the inductor device according to the present invention, the assembly work can be simplified and the saving of burning energy can be achieved, thereby making the product cheaper and having a predetermined characteristic, thereby improving quality and characteristics. Therefore, it is possible to provide an ideal device.
