本考案は貫通形コンデンサに関する。 The present invention relates to a feedthrough capacitor.
【０００２】0002
従来の貫通形コンデンサは、図３に示すように、外周面に外部電極ａが形成さ れた筒形誘電体ｂの断面円形の貫通孔ｃに断面円形のリード線ｄを挿通し、リー ド線ｄを貫通孔ｃの壁面に形成された内部電極に半田付けした構成になっており 、例えば電子機器のシャーシｅの孔ｆに挿入して外部電極ａをシャーシｅに半田 付けし、リード線ｄは折り曲げてプリント基板ｇの孔ｈに挿通し、配線部ｉに半 田付けされる。 As shown in Fig. 3, a conventional feedthrough capacitor has an external electrode a formed on its outer peripheral surface. A lead wire d having a circular cross section is inserted into a through hole c having a circular cross section in the cylindrical dielectric body b. The wire d is soldered to the internal electrode formed on the wall of the through hole c. For example, insert the external electrode a into the hole f of the chassis e of an electronic device and solder the external electrode a to the chassis e. Then, bend the lead wire d, insert it into the hole h of the printed circuit board g, and insert it halfway into the wiring part i. It is planted in rice fields.
【０００３】0003
前述のコンデンサのリード線ｄの端部とプリント基板ｇの孔ｈが合わないとき は、リード線ｄの端部を、孔ｈに差し込むために紙面と直角方向に力を加える。 このときリード線に加える力は筒形誘電体ｂの内部電極とリード線ｄの接着部に ねじれ力として加わり、この力が内部電極とリード線ｄを接着する接着剤（半田 ）の接着強度を上回るときは、接着が破壊され、リード線ｄと内部電極との電気 的接続が悪くなってコンデンサとしての機能が損われる。 When the end of the lead wire d of the capacitor mentioned above does not align with the hole h of the printed circuit board g applies force in a direction perpendicular to the plane of the paper in order to insert the end of the lead wire d into the hole h. At this time, the force applied to the lead wire is applied to the bond between the internal electrode of the cylindrical dielectric body b and the lead wire d. This force is added as a twisting force, and this force is applied to the adhesive (solder) that adheres the internal electrode and lead wire d. ), the bond is broken and the electricity between the lead wire d and the internal electrode is The connection between the capacitors and the capacitors becomes poor and the function as a capacitor is impaired.
【０００４】 本考案は、従来のコンデンサのこのような課題を解決することをその目的とす るものである。0004 The purpose of this invention is to solve these problems with conventional capacitors. It is something that
【０００５】[0005]
本考案は、上記の目的を達成するために、筒形誘電体の外周面に外部電極を形 成し、貫通孔の壁面に内部電極を形成し、貫通孔に挿通したリード線を内部電極 に導電接着剤で接着した貫通形コンデンサにおいて、貫通孔を円形以外の形状と し、リード線の貫通孔挿通部の断面を円形以外の形状としたことを特徴とする。 In order to achieve the above objectives, this invention forms external electrodes on the outer peripheral surface of a cylindrical dielectric. An internal electrode is formed on the wall of the through hole, and the lead wire inserted through the through hole is connected to the internal electrode. In feed-through capacitors that are bonded with conductive adhesive to the The present invention is characterized in that the cross section of the lead wire insertion portion through the through hole has a shape other than circular.
【０００６】[0006]
リード線の貫通孔挿通部にねじれ力が作用したとき、リード線及び貫通孔の断 面が非円形であるので、リード線に加わるねじれ力は直接筒形誘電体に加わり、 接着剤に加わらない。したがって、リード線と内部電極との接着は損われず、コ ンデンサの機能は保持される。 When a twisting force is applied to the part where the lead wire passes through the through hole, the lead wire and the through hole may break. Since the surface is non-circular, the twisting force applied to the lead wire is applied directly to the cylindrical dielectric, Does not add to adhesive. Therefore, the adhesion between the lead wire and the internal electrode is not impaired, and the core The function of the capacitor is retained.

以下本考案の実施例を図面につき説明する。 Embodiments of the present invention will be described below with reference to the drawings.
【０００８】 図１及び図２は本考案の一実施例を示す。[0008] 1 and 2 show an embodiment of the present invention.
【０００９】 同図において、筒形誘電体１は、例えば外径の大径部が４．６mmφ、小径部が ３．０mmφ、長さが３．２mmの大きさを有し、その中心に４角形の貫通孔２が、 該誘電体１の一端面に貫通孔２に連なる外周形状が６角形の凹部３がそれぞれ形 成され、貫通孔２及び凹部３の壁面に内部電極４が形成され、該誘電体１の外周 面に外部電極５が形成されている。内部電極４及び外部電極５はいずれも例えば ニッケル、銅及び半田のメッキにより形成されたものである。[0009] In the figure, the cylindrical dielectric 1 has a large diameter part of 4.6 mmφ and a small diameter part, for example. It has a size of 3.0 mmφ and a length of 3.2 mm, and has a rectangular through hole 2 in the center. A recess 3 having a hexagonal outer circumference connected to the through hole 2 is formed on one end surface of the dielectric 1. An internal electrode 4 is formed on the walls of the through hole 2 and the recess 3, and the outer periphery of the dielectric 1 is External electrodes 5 are formed on the surface. Both the internal electrode 4 and the external electrode 5 are, for example, It is formed by plating nickel, copper, and solder.
【００１０】 リード線６は、この実施例では、貫通孔２への挿通部が断面４角形に形成され たもので、これを貫通孔２に挿入した後、半田槽に筒形誘電体１を浸漬して凹部 ３及び貫通孔２に導電接着剤である半田７を充填し、半田７によりリード線６を 内部電極４に半田付けし、外部電極５に半田を被着形成する。0010 In this embodiment, the insertion portion of the lead wire 6 into the through hole 2 is formed to have a rectangular cross section. After inserting this into the through hole 2, immerse the cylindrical dielectric 1 in a solder bath to form the recess. 3 and the through hole 2 are filled with solder 7, which is a conductive adhesive, and the lead wire 6 is connected with the solder 7. The internal electrodes 4 are soldered, and the external electrodes 5 are coated with solder.
【００１１】 以上のようにして形成された貫通形コンデンサは、小径部を例えばシャーシ８ の孔に嵌入して外部電極５をシャーシ８に半田付けし、リード線６は直角方向に 折曲してその端部を図示しないプリント基板の配線部に半田付けする。[0011] The feedthrough capacitor formed as described above has a small diameter portion attached to the chassis 8, for example. solder the external electrode 5 to the chassis 8, and the lead wire 6 in the right angle direction. Bend it and solder the end to the wiring part of a printed circuit board (not shown).
【００１２】 配線部に接続するためにリード線６の端部に力を加え、リード線６の貫通孔挿 入部にねじれ力を加えたとき、その力は筒形誘電体１に直接加わってこれに吸収 され、半田７には力が加わらず、リード線６は内部電極４から剥離しない。この 実施例では、半田溜り部である凹部３の外周形状は６角形状になっているので、 リード線６にねじり力が加わったとき、凹部３においては、力は６角形の半田７ から誘電体１の６角形の凹部３の壁面に作用し、この壁面で吸収される。0012 Apply force to the end of the lead wire 6 to connect it to the wiring part, and insert the lead wire 6 into the through hole. When a torsional force is applied to the input part, the force is directly applied to the cylindrical dielectric 1 and absorbed by it. Therefore, no force is applied to the solder 7, and the lead wire 6 does not peel off from the internal electrode 4. this In the embodiment, the outer periphery of the recess 3, which is the solder pool, is hexagonal. When a twisting force is applied to the lead wire 6, the force is applied to the hexagonal solder 7 in the recess 3. It acts on the wall of the hexagonal recess 3 of the dielectric 1 and is absorbed by this wall.
【００１３】 前記誘電体１の貫通孔２の形状は、４角形の他、３角形、５角形、６角形ある いは楕円形等円形以外の形状でもよく、リード線６は、少なくとも貫通孔挿通部 が貫通孔２の形状に合った形状のものを使用する。[0013] The shape of the through hole 2 of the dielectric 1 is not only quadrangular but also triangular, pentagonal, and hexagonal. Alternatively, the lead wire 6 may have a shape other than a circular shape such as an ellipse. Use one whose shape matches the shape of the through hole 2.
【００１４】 また、前記凹部３の外周形状は円形でもよく、凹部３を形成しなくてもよい。[0014] Further, the outer peripheral shape of the recess 3 may be circular, and the recess 3 does not need to be formed.
【００１５】[0015]
本考案は、上述の通りの構成を有するから、他の配線部に接続するためにリー ド線の端部に力を加えてもリード線と内部電極との接着が損われることがなく、 コンデンサの機能が保持される効果を有する。 Since the present invention has the above-mentioned configuration, the present invention has a lead for connecting to other wiring parts. Even if force is applied to the end of the lead wire, the adhesion between the lead wire and the internal electrode will not be damaged. This has the effect of maintaining the function of the capacitor.
