Description
【0001】[0001]
本考案は、主としてコモンモードチョークコイルとして用いられる巻線体の構 造に関する。 The present invention mainly relates to the structure of a winding body used as a common mode choke coil.
【0002】[0002]
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.
【0003】[0003]
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.
【0005】[0005]
このような目的を達成するために、本考案の巻線体においては、コア両端部そ れぞれの鍔の一側面に、巻回された巻線の引き出し線を接続する一対の電極が形 成されていることを特徴としている。 In order to achieve such an object, in the winding body of the present invention, a pair of electrodes for connecting the lead wire of the wound winding is formed on one side of each brim at each end of the core. It is characterized by being made.
【0006】[0006]
コアに巻線を巻回し、コア両端部それぞれの鍔の一側面上の電極に、巻線の引 き出し線を接続する。 The winding is wound around the core, and the lead wire of the winding is connected to the electrodes on one side of the collar at both ends of the core.
【0007】[0007]
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1 4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3 0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.
【0013】[0013]
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.
