【従来の技術】[Prior Art]

図５は環状コアに巻線が巻回された巻線体の分解斜視図であり、図６はその組み立て斜視図である。この巻線体１は環状コア２を有する。環状コア２には巻線４がバイファイラに巻回されている。環状コア２は、一対のケース６間にセットされ、巻線４それぞれの引き出し線８がケース下端部の巻線端子１０に絡げられた状態で半田付けで固定されている。 FIG. 5 is an exploded perspective view of a winding body in which a winding is wound around an annular core, and FIG. 6 is an assembled perspective view thereof. The winding body 1 has an annular core 2. A winding 4 is wound around the annular core 2 around a bifilar. The annular core 2 is set between a pair of cases 6, and the lead wires 8 of the windings 4 are fixed by soldering in a state of being entwined with the winding terminals 10 at the lower end of the case.

【考案が解決しようとする課題】[Problems to be solved by the device]

上記巻線体１では、環状コア２に巻線４を環状巻きする構造であるから、巻線４を手巻きでしか巻回できず、量産性にたいへん劣り、製造コストも高くつくものである。また、環状コア２とは別に上記のような巻線端子１０付きのケース６が必要な分、全体のサイズが大型化し、しかもそれだけ製造コストも高くつくものとなるうえに、ケース６の巻線端子１０があるために回路基板上などへの面実装には適さない。さらに、環状コア２を用いているので巻線４の巻始め端、巻終り端がどうしても近接して位置されるため、その間に浮遊容量を生じ易く、特性に悪影響を与えていた。 Since the winding body 1 has a structure in which the winding wire 4 is wound around the annular core 2, the winding wire 4 can be wound only by manual winding, which is very inferior in mass productivity and high in manufacturing cost. In addition to the ring-shaped core 2, the case 6 with the winding terminal 10 as described above is required, so that the entire size is increased and the manufacturing cost is increased accordingly. The terminal 10 is not suitable for surface mounting on a circuit board or the like. Furthermore, since the winding core 4 is used, the winding start end and the winding end end of the winding 4 are inevitably located close to each other, and stray capacitance is likely to occur between them, which adversely affects the characteristics.

【０００４】したがって、本考案においては、量産性に優れた、製造コストも安価に済むのみならず、回路基板などへの面実装も可能で特性の良好な巻線体を提供することを目的としている。Therefore, the object of the present invention is to provide a winding body which is excellent in mass productivity, can be manufactured at low cost, and can be surface-mounted on a circuit board or the like and has good characteristics. I am trying.

It is characterized by being made.

【実施例】【Example】

以下、本考案の一実施例を図面を参照して詳細に説明する。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

【０００８】図１は、本考案の実施例に係る巻線体の斜視図であり、この巻線体１２は、断面矩形状のコア１４を有し、このコア１４は両端部のそれぞれに鍔１６を有している。両鍔１６は、ほぼ同一形状とされ、それぞれその一側面中央を所要深さの凹部１８に形成することで、該凹部１８を間にして一対の巻線端部取付柱２０が形成されている。一対の各巻線端部取付柱２０の上端部は、先端部が縮径されるとともに、銀塗装やメッキされた電極部２２に形成されている。そして、コア１４にバイファイラに巻回された巻線２４のそれぞれ４本の引き出し線２６は各電極部２２に絡げられた状態で半田付けで電気的かつ機械的に接続固定される。FIG. 1 is a perspective view of a winding body according to an embodiment of the present invention. The winding body 12 has a core 14 having a rectangular cross section, and the core 14 is provided at both ends. It has a collar 16. Both the collars 16 have substantially the same shape, and by forming a recess 18 having a required depth at the center of one side surface thereof, a pair of winding end mounting columns 20 are formed with the recess 18 therebetween. .. The upper end of each of the pair of winding end mounting columns 20 is formed with a silver-painted or plated electrode portion 22 while the tip end is reduced in diameter. Then, each of the four lead wires 26 of the winding wire 24 wound around the core 14 by the bifilar is electrically and mechanically connected and fixed by soldering while being entwined with each electrode portion 22.

【０００９】上記構造の巻線体１２は、各電極部２２の高さが同一であるから、回路基板上に搭載して該回路基板に面実装できるとともに、コア１４には巻線機による巻線が可能であるから量産性に優れ製造コストの低減が可能なものであり、さらに、巻線の引き出し線を絡げるための巻線端子を備えたケースも不要化し製造コストの一層の低減が可能なものである。Since the winding body 12 having the above structure has the same height of each electrode portion 22, it can be mounted on a circuit board and surface-mounted on the circuit board, and the core 14 is wound by a winding machine. Since it is possible to wire, mass production is excellent and the manufacturing cost can be reduced. Furthermore, the case with a winding terminal for entwining the lead wire of the winding is not required and the manufacturing cost is further reduced. Is possible.

【００１０】なお、上述の実施例では、電極部２２を鍔１６の電極柱２０上に形成したが、図２のように鍔１６の一側面中央を凸部２８形状とし、この凸部両側に電極部３０を形成し、該電極部３０に引き出し線２６を熱圧着等で電気的かつ機械的に固定接続してもよい。Although the electrode portion 22 is formed on the electrode column 20 of the collar 16 in the above-described embodiment, the center of one side surface of the collar 16 is formed into a convex portion 28 as shown in FIG. The electrode portion 30 may be formed, and the lead wire 26 may be electrically and mechanically fixedly connected to the electrode portion 30 by thermocompression bonding or the like.

【００１１】また、上述の実施例では、鍔１６の端面１６ａに穴が無かったが、図３のように該端面１６ａにスピンドル端部の挿通可能な径の穴３２を設け、この穴３２にスピンドル端部を挿入し該スピンドルを回転させてコア１４に巻線を施すようにしてもよい。Further, in the above-mentioned embodiment, the end surface 16a of the collar 16 has no hole, but as shown in FIG. 3, the end surface 16a is provided with a hole 32 having a diameter through which the spindle end can be inserted. Alternatively, the end of the spindle may be inserted and the spindle may be rotated to wind the core 14.

【００１２】なお、図１ないし図３のようにコア１４への巻線を行い、その引き出し線を電極部に半田付けしてのちは、巻線体の両側面に図４のようにそれぞれケース３６を取り付けるとともに、内部に絶縁樹脂３８を注入することで製品化される。It should be noted that after winding the core 14 as shown in FIGS. 1 to 3 and soldering the lead wires to the electrode parts, the winding body is wound on both side surfaces as shown in FIG. The product is commercialized by attaching the case 36 and injecting the insulating resin 38 inside.

【考案の効果】[Effect of the device]

以上のように本考案によれば、コア両端部それぞれの鍔の一側面に、バイファイラに巻回された巻線の引き出し線が接続される一対の電極を形成したから、例えば従来のようにケースを用意し、そのケース下端部に巻線端子を設け、その巻線端子に引き出し線を接続させる必要がなくなり、結果、量産性に優れかつ製造コストの低減が可能なものとなる。また、鍔に電極を形成したから、回路基板などへの面実装も可能となる。さらに、巻回された巻線の両端が離れて位置することになるので、その間に浮遊容量が発生して悪影響を及ぼすこともない。 As described above, according to the present invention, a pair of electrodes to which the lead wires of the winding wound around the bifilament are connected are formed on one side surface of each of the flanges at both ends of the core. It is not necessary to prepare a case, provide a winding terminal at the lower end of the case, and connect a lead wire to the winding terminal. As a result, mass productivity is excellent and manufacturing cost can be reduced. Further, since the electrodes are formed on the flange, surface mounting on a circuit board or the like is possible. Furthermore, since both ends of the wound winding are located apart from each other, stray capacitance is not generated between them, and there is no adverse effect.
