本発明に係るコンデンサ及びその製造方法を実施するための形態を、コンデンサとして電解コンデンサを例示して実施例に基づいて以下に説明する。
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mode for carrying out a capacitor and a method for manufacturing the same according to the present invention will be described below based on an example with an electrolytic capacitor as an example.
実施例1に係る電解コンデンサにつき、図1から図5を参照して説明する。図1に示されるように、電解コンデンサ5は、高純度アルミニウム箔を電気化学的に粗面化したあと、陽極酸化を行い、誘電体酸化皮膜を形成してなる陽極箔と粗面化した陰極アルミニウム箔に各々リード線3を接続し、かつセパレータを介して巻回して構成したコンデンサ素子1を、駆動用電解液とともに有底筒状(円筒形状)の外装ケース2に収納し、該ケース2の開放端に封口板4を嵌入して加締め、封口したコンデンサ本体からなる。
The electrolytic capacitor according to Example 1 will be described with reference to FIGS. As shown in FIG. 1, the electrolytic capacitor 5 includes a high-purity aluminum foil that is electrochemically roughened and then anodized to form a dielectric oxide film and a roughened cathode. Capacitor elements 1 each formed by connecting lead wires 3 to aluminum foil and wound through a separator are housed in a bottomed cylindrical (cylindrical) outer case 2 together with a driving electrolyte, and the case 2 It is composed of a capacitor body that is sealed by inserting and sealing the sealing plate 4 at the open end.
尚、本実施例の封口板4は、ゴム材からなるが、封口板の材質は必ずしも上記に限られず、絶縁性を備えていればよく、弾性変形可能な樹脂等の材質であれば好ましい。
In addition, although the sealing board 4 of a present Example consists of rubber materials, the material of a sealing board is not necessarily restricted to the above, What is necessary is just to provide insulation, and it is preferable if it is a material, such as resin which can be elastically deformed.
封口板4を貫通して引き出されるリード線3は、実装基板6に設けられた2つの貫通孔7に貫通されるとともに、実装基板6の外表面に半田付け16等により固定される。なお、リード線3の実装基板6への取り付けは、図1に示すものに限らず、例えば貫通孔7を貫通したリード線3の先端を折曲げて固定してもよいし、さらにはこの折り曲げ部から先において半田付け等により実装基板6へ固定してもよいし、種々の形式のものを採用できることはいうまでもない。
The lead wire 3 drawn out through the sealing plate 4 is penetrated through two through holes 7 provided in the mounting substrate 6 and fixed to the outer surface of the mounting substrate 6 by soldering 16 or the like. Note that the attachment of the lead wire 3 to the mounting substrate 6 is not limited to that shown in FIG. 1. For example, the tip of the lead wire 3 that penetrates the through hole 7 may be bent and fixed. Needless to say, it may be fixed to the mounting substrate 6 by soldering or the like from the part to the end, and various types of parts can be adopted.
電解コンデンサ5のコンデンサ本体には、外装ケース2の外周を覆う略円筒形状をなす耐振部材10が嵌合され、コンデンサ本体は耐振部材10を介して実装基板6に固定されるようになっている。
The capacitor body of the electrolytic capacitor 5 is fitted with a vibration-proof member 10 having a substantially cylindrical shape covering the outer periphery of the outer case 2, and the capacitor body is fixed to the mounting substrate 6 via the vibration-proof member 10. .
図3及び図4に示すように、耐振部材10は、電解コンデンサ5の外装ケース2に嵌合されるバンド部11とバンド部11の一端から延出される端子部12を有する。耐振部材10のバンド部11は、外装ケース2に嵌合された状態で加締めにより強固に固定される。加締め手段は、特に限定されるものではなく、外装ケース2にバンド部11を嵌合した状態(例えば図示しないチャッキング手段でバンド部11を外装ケース2に押さえ付ける等の状態)において、例えば、ロール加締め手段19の加締めロールをバンド部11の外周に押圧させ、図1に示すような加締め部13を形成する。耐振部材10の材質は、加締めにより塑性変形可能なものであればよく、例えば、アルミニウムなどの金属材料等が好ましい。
As shown in FIGS. 3 and 4, the vibration-proof member 10 has a band part 11 fitted to the outer case 2 of the electrolytic capacitor 5 and a terminal part 12 extending from one end of the band part 11. The band portion 11 of the vibration proof member 10 is firmly fixed by caulking while being fitted to the exterior case 2. The crimping means is not particularly limited. In a state where the band portion 11 is fitted to the outer case 2 (for example, a state where the band portion 11 is pressed against the outer case 2 by a chucking means (not shown)), for example, The caulking roll of the roll caulking means 19 is pressed against the outer periphery of the band portion 11 to form the caulking portion 13 as shown in FIG. The vibration-resistant member 10 may be made of any material as long as it can be plastically deformed by caulking. For example, a metal material such as aluminum is preferable.
加締めにより形成される加締め部13は、耐振部材10の外周に沿って形成され、連続した環状、あるいは、非連続の環状をなしている。また、加締め部13は、封口板4の加締め部9に対応する外装ケース2の位置を避けることが好ましい。さらには、加締め部13は、耐振部材10のバンド部11の高さ方向の中心付近又は、外装ケース2の高さ方向の中央付近、特には電解コンデンサ5の重心付近に設けられるのが好ましい。さらに、加締め部13は、1箇所に限らず、外装ケース2の高さ方向の複数箇所設けられてもよい。
The caulking portion 13 formed by caulking is formed along the outer periphery of the vibration-proof member 10 and has a continuous annular shape or a discontinuous annular shape. Moreover, it is preferable that the crimping part 13 avoids the position of the exterior case 2 corresponding to the crimping part 9 of the sealing plate 4. Furthermore, the crimping portion 13 is preferably provided in the vicinity of the center in the height direction of the band portion 11 of the vibration proof member 10 or in the vicinity of the center in the height direction of the exterior case 2, particularly in the vicinity of the center of gravity of the electrolytic capacitor 5. . Further, the crimping portion 13 is not limited to one location, and may be provided at a plurality of locations in the height direction of the exterior case 2.
加締め部13の加締め深さは、例えば、約0.5mm程度であり、本例においては、外装ケース2の内面とコンデンサ素子1の外面との間に所定間隔(0.5mm以上)の空隙部が設けられており、加締めた際に外装ケース2の加締め部13がコンデンサ素子1に当たらないように設定される。このため、加締めによるコンデンサ素子1へのストレスを回避することができる。
The caulking depth of the caulking portion 13 is, for example, about 0.5 mm. In this example, a predetermined interval (0.5 mm or more) is provided between the inner surface of the outer case 2 and the outer surface of the capacitor element 1. A gap is provided, and is set so that the crimped portion 13 of the outer case 2 does not hit the capacitor element 1 when crimped. Therefore, stress on the capacitor element 1 due to caulking can be avoided.
図2に示すように、バンド部11の加締めされる部分の一部には上下方向に延びる長孔14が設けられてもよい。バンド部11の加締めされる部分の一部に長孔14が設けられると、加締められた際に、外装ケース2の一部がバンド部11の長孔14に入り込み、外装ケース2と耐振部材10との周方向の相対的回転を防止することができる。すなわち長孔14は、加締めにより変形する外装ケース2の一部の逃げ代部分として機能する。なお、孔の形状は、長孔に限られず、例えば円孔でもよいし矩形孔であっても構わない。
As shown in FIG. 2, a long hole 14 extending in the vertical direction may be provided in a part of the band portion 11 to be crimped. If the elongated hole 14 is provided in a part of the band part 11 to be crimped, when the crimping is performed, a part of the outer case 2 enters the elongated hole 14 of the band part 11 and the outer case 2 and vibration resistant The relative rotation in the circumferential direction with the member 10 can be prevented. That is, the long hole 14 functions as a part of the clearance allowance of the outer case 2 that is deformed by caulking. The shape of the hole is not limited to the long hole, and may be, for example, a circular hole or a rectangular hole.
バンド部11の一端から延出される端子部12は、好ましくは、周方向に複数設けられるが特に個数が限定されるものではない。図3に示すものでは、周方向に等間隔で4個設けられている。個々の端子部12の長さ及び幅は、電解コンデンサ5の装着される装置の振動状態、あるいは、実装基板6に対する耐振部材10の具体的な装着手法に応じて設計的に最適な値に設定される。図1に示すように、実装基板6に設けられた貫通孔15に端子部12が嵌入され、半田付け16により固定される場合、端子部12の長さは実装基板6から数ミリ突出する程度に設定される。なお、この端子部12は、上述した電解コンデンサのリード線3と同様に、実装基板6の貫通孔15を貫通した端子部12の先端を折曲げて固定してもよいし、さらにはこの折り曲げ部から先において半田付け等により実装基板6へ固定してもよい。また、この端子部12は、別途半田付けが円滑に行えるように、端子部12の表面に半田メッキ等が施されていると良い。またさらには、この端子部12は、バンド部11とは別の材料、例えば半田メッキが施された金属線や条(個片や板状のものを含む)を溶接等の接続にてバンド部11の一端に形成することもできる。
A plurality of terminal portions 12 extending from one end of the band portion 11 are preferably provided in the circumferential direction, but the number is not particularly limited. In the case shown in FIG. 3, four are provided at equal intervals in the circumferential direction. The lengths and widths of the individual terminal portions 12 are set to optimum values in terms of design according to the vibration state of the device to which the electrolytic capacitor 5 is mounted or the specific mounting method of the vibration-proof member 10 to the mounting substrate 6. Is done. As shown in FIG. 1, when the terminal portion 12 is inserted into a through hole 15 provided in the mounting substrate 6 and fixed by soldering 16, the length of the terminal portion 12 protrudes from the mounting substrate 6 by several millimeters. Set to The terminal portion 12 may be fixed by bending the tip of the terminal portion 12 penetrating the through hole 15 of the mounting substrate 6, as in the case of the lead wire 3 of the electrolytic capacitor described above. You may fix to the mounting board | substrate 6 by soldering etc. from a part ahead. Further, the terminal portion 12 is preferably provided with solder plating or the like on the surface of the terminal portion 12 so that the soldering can be smoothly performed separately. Still further, the terminal portion 12 is made of a material different from that of the band portion 11, such as a metal wire or strip (including individual pieces or plate-like ones) plated with solder by connecting the band portion by welding or the like. 11 can also be formed at one end.
加締めにより耐振部材10が電解コンデンサ5に強固に固定され、また、耐振部材10の端子部12を介して電解コンデンサ5が実装基板6へ十分な強度で装着されることにより、実装した後に外部からの衝撃や振動に十分耐えうる強度を備えた構造を有する電解コンデンサ5を製造し、当該電解コンデンサ5を得ることができる。
The vibration-proof member 10 is firmly fixed to the electrolytic capacitor 5 by caulking, and the electrolytic capacitor 5 is attached to the mounting substrate 6 with sufficient strength via the terminal portion 12 of the vibration-proof member 10, so that it is externally mounted. It is possible to manufacture the electrolytic capacitor 5 having a structure with sufficient strength to withstand shocks and vibrations, and to obtain the electrolytic capacitor 5.
図3に示すように、バンド部11の端子部12の設けられる端部には、凸部17が延出されている。例えば、図4の矢印に示すように、電解コンデンサ5に対して耐振部材10が下方から嵌入される場合、電解コンデンサ5と耐振部材10との高さ方向の相対的位置が調整され、凸部17の位置と電解コンデンサ5の端面位置を合わせた状態で加締め固定できる。具体的には、凸部17の位置と電解コンデンサ5の端面位置となる封口板4に設けた段部8や、この段部8がない電解コンデンサでは、外装ケース2の端面の加締め部位との高さ位置とを合わせた状態とする。この場合、図1に示すように、電解コンデンサ5と実装基板6との間に間隙を設けることができ、電解コンデンサ5と実装基板6との間に存在する空気の抜けを良好にすることができる。なお、凸部17を塑性変形可能に形成してもよく、この凸部17を任意の部位で折り曲げることで、当該折り曲げ部位が電解コンデンサ5の端部に引っ掛かり、電解コンデンサ5と耐振部材10との高さ方向の相対的位置を最適な状態に制御することができる。
As shown in FIG. 3, the convex part 17 is extended in the edge part in which the terminal part 12 of the band part 11 is provided. For example, as shown by the arrow in FIG. 4, when the vibration proof member 10 is inserted into the electrolytic capacitor 5 from below, the relative position in the height direction of the electrolytic capacitor 5 and the vibration proof member 10 is adjusted, and the convex portion Clamping and fixing can be performed with the position of 17 and the end face position of the electrolytic capacitor 5 being matched. Specifically, in the step portion 8 provided on the sealing plate 4 serving as the position of the convex portion 17 and the end face position of the electrolytic capacitor 5, or in an electrolytic capacitor without this step portion 8, It is assumed that the height position is matched. In this case, as shown in FIG. 1, a gap can be provided between the electrolytic capacitor 5 and the mounting substrate 6, and air escape between the electrolytic capacitor 5 and the mounting substrate 6 can be improved. it can. The convex portion 17 may be formed so as to be plastically deformable. By bending the convex portion 17 at an arbitrary portion, the bent portion is caught on the end of the electrolytic capacitor 5, and the electrolytic capacitor 5 and the vibration-proof member 10 The relative position in the height direction can be controlled to an optimum state.
凸部17は、好ましくは、周方向に複数設けられるが特に個数が限定されるものではない。図3に示すものでは、隣接する端子部12の間に位置して周方向に等間隔で4個設けられている。なお、この凸部17が実装基板6の実装面に当接することで、電解コンデンサ5と実装基板6との高さ位置が制御される。
Preferably, a plurality of convex portions 17 are provided in the circumferential direction, but the number is not particularly limited. In the example shown in FIG. 3, four pieces are provided at equal intervals in the circumferential direction located between adjacent terminal portions 12. Note that the height positions of the electrolytic capacitor 5 and the mounting substrate 6 are controlled by the projections 17 coming into contact with the mounting surface of the mounting substrate 6.
図5は、電解コンデンサ5の外装ケース2に耐振部材10が嵌合され、加締めにより固定された状態を示す斜視図である。図5において、図1ないし図4の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。図5によれば、加締め部13により耐振部材10が電解コンデンサ5に強固に固定されていることがわかる。また、耐振部材10の端子部12を介して電解コンデンサ5が実装基板6へ十分な接着強度で装着されることから、実装した後に外部からの衝撃や振動に十分耐えうる強度を備えた構造を有する電解コンデンサ5を得ることができる。
FIG. 5 is a perspective view showing a state in which the vibration-proof member 10 is fitted to the outer case 2 of the electrolytic capacitor 5 and fixed by caulking. In FIG. 5, the same reference numerals as those in FIGS. 1 to 4 indicate the same members, and redundant descriptions are omitted. As can be seen from FIG. 5, the vibration-proof member 10 is firmly fixed to the electrolytic capacitor 5 by the caulking portion 13. In addition, since the electrolytic capacitor 5 is attached to the mounting substrate 6 with sufficient adhesive strength via the terminal portion 12 of the vibration-proof member 10, a structure having a strength that can sufficiently withstand external impact and vibration after mounting. Thus, the electrolytic capacitor 5 can be obtained.
このように、本実施例では、電解コンデンサ5は、コンデンサ素子1が有底筒状の外装ケ-ス2内部に格納され、その開口部が封口板4により封口されるとともに、封口板4を貫通させて引き出されるリード線3を有する電解コンデンサにおいて、電解コンデンサ5の外装ケース2に嵌合されるバンド部11とバンド部11の一端から延出される端子部12を有する耐振部材10を備え、耐振部材10は、電解コンデンサ5の外装ケース2にバンド部11が加締めにより固定されることにより、耐振部材10が電解コンデンサ5に強固に固定され、また、耐振部材10の端子部12を介して電解コンデンサ5が実装基板6へ十分な強度で装着され、もって、実装した後に外部からの衝撃や振動に十分耐えうる強度を備えた構造を有する電解コンデンサ5を得ることができる。
Thus, in this embodiment, the electrolytic capacitor 5 includes the capacitor element 1 housed in the bottomed cylindrical outer case 2, the opening thereof being sealed by the sealing plate 4, and the sealing plate 4 being An electrolytic capacitor having a lead wire 3 that is led through and includes a vibration-proof member 10 having a band portion 11 fitted to the outer case 2 of the electrolytic capacitor 5 and a terminal portion 12 extending from one end of the band portion 11, The vibration proof member 10 is firmly fixed to the electrolytic capacitor 5 by fixing the band portion 11 to the outer case 2 of the electrolytic capacitor 5 by caulking, and is also connected via the terminal portion 12 of the vibration proof member 10. The electrolytic capacitor 5 is mounted on the mounting substrate 6 with sufficient strength, so that the electrolytic capacitor 5 has sufficient strength to withstand external shocks and vibrations after mounting. It is possible to obtain a capacitor 5.
またこのように、本実施例では、電解コンデンサ5は、バンド部11の加締めされる部分13の一部に長孔14が設けられることにより、加締めた際に、外装ケース2の一部がバンド部11の長孔14に入り込み、外装ケース2と耐振部材10との相対的回転を防止することができる。
As described above, in this embodiment, the electrolytic capacitor 5 is provided with a long hole 14 in a part of the portion 13 to which the band portion 11 is crimped. Can enter the elongated hole 14 of the band portion 11 and prevent relative rotation between the exterior case 2 and the vibration-proof member 10.
またこのように、本実施例では、電解コンデンサ5は、端子部12が設けられるバンド部11の一端に塑性変形可能な凸部17が延出されることにより、塑性変形可能な凸部17を利用して加締める際の電解コンデンサ5と耐振部材10との高さ方向の相対的位置を制御することができる。また、塑性変形可能な凸部17を利用して電解コンデンサ5と実装基板6との間に間隙を設けることができ、電解コンデンサ5と実装基板6との間に存在する空気の抜けを良好にすることができる。
As described above, in this embodiment, the electrolytic capacitor 5 uses the convex portion 17 that can be plastically deformed by extending the convex portion 17 that can be plastically deformed at one end of the band portion 11 on which the terminal portion 12 is provided. Thus, the relative position in the height direction between the electrolytic capacitor 5 and the vibration-proof member 10 when crimping can be controlled. Moreover, a gap can be provided between the electrolytic capacitor 5 and the mounting substrate 6 by using the plastically deformable convex portion 17, and air escape existing between the electrolytic capacitor 5 and the mounting substrate 6 can be improved. can do.
またこのように、本実施例では、電解コンデンサ5は、加締めにより形成される加締め部13は、連続した環状または非連続の環状をなしていることにより、加締め部13の形成をロール加締め手段等により行うことができ、特別な手段を用いることなく耐振部材10を電解コンデンサ5に強固に固定することができる。
In this way, in this embodiment, the electrolytic capacitor 5 is formed by caulking part 13 formed by caulking, so that the caulking part 13 is formed by forming a continuous annular shape or a non-continuous annular shape. The vibration-proof member 10 can be firmly fixed to the electrolytic capacitor 5 without using any special means.
またこのように、本実施例では、電解コンデンサ5は、加締め部13の深さは、外装ケース2がコンデンサ素子1に当接しないように設定されることにより、加締めによるコンデンサ素子1へのストレスを回避することができる。
As described above, in the present embodiment, the depth of the caulking portion 13 of the electrolytic capacitor 5 is set so that the outer case 2 does not contact the capacitor element 1. Can avoid the stress.
図6を参照しながら、実施例2に係る電解コンデンサについて説明する。実施例2においては、加締め部13の深さが実施例1と相違するが、その他の点では実施例1と同じであり、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 2 will be described with reference to FIG. In the second embodiment, the depth of the caulking portion 13 is different from that of the first embodiment, but is otherwise the same as the first embodiment, and the same reference numerals as those in FIGS. 1 to 5 indicate the same members. Therefore, a duplicate description is omitted.
図6に示すように、加締め部13の深さは、外装ケース2がコンデンサ素子1に当接するように設定され、また、コンデンサ素子1の外周には緩衝部材18が設けられている。このため、加締めによりコンデンサ素子1も固定することができ、その際、緩衝部材18が外装ケース2とコンデンサ素子1との間に介在され、外装ケース2の加締め部13のコンデンサ素子1への押圧力が緩和されるため、コンデンサ素子1に作用するストレスを低減することができる。
As shown in FIG. 6, the depth of the caulking portion 13 is set so that the outer case 2 contacts the capacitor element 1, and a buffer member 18 is provided on the outer periphery of the capacitor element 1. For this reason, the capacitor element 1 can also be fixed by caulking. At this time, the buffer member 18 is interposed between the outer case 2 and the capacitor element 1, and is connected to the capacitor element 1 of the caulking portion 13 of the outer case 2. Therefore, the stress acting on the capacitor element 1 can be reduced.
緩衝部材18は、例えば、巻きとめテープを複数周巻いて構成してもよく、あるいは、コンデンサ素子1を構成する陽極箔と陰極アルミニウム箔との間に介在するセパレータ(図示省略)を複数周空巻きするなどして構成してもよい。なお、緩衝部材18は、巻きとめテープあるいはセパレータに限らず、例えば、緩衝作用のあるゴムバンド等を使用してもよい。尚、図6では、加締め部13がコンデンサ素子1に当接する位置にのみ緩衝部材18が設けられているが、コンデンサ素子1の外周面全体を緩衝部材18で覆うようにしてもよい。
For example, the buffer member 18 may be formed by winding a plurality of winding tapes, or a plurality of separators (not shown) interposed between the anode foil and the cathode aluminum foil constituting the capacitor element 1 may be formed. You may comprise by winding etc. The buffer member 18 is not limited to a winding tape or a separator, and for example, a rubber band having a buffering action may be used. In FIG. 6, the buffer member 18 is provided only at a position where the caulking portion 13 contacts the capacitor element 1, but the entire outer peripheral surface of the capacitor element 1 may be covered with the buffer member 18.
このように、実施例2では、電解コンデンサ5は、加締め部13の深さが、外装ケース2がコンデンサ素子1に当接するように設定され、また、コンデンサ素子1の外周に緩衝部材18が設けられることにより、加締めによりコンデンサ素子1も固定することができ、その際、緩衝部材18が外装ケース2とコンデンサ素子1との間に介在され、外装ケース2の加締め部13のコンデンサ素子1への押圧力が緩和されるため、コンデンサ素子1へのストレスを低減することができる。
Thus, in Example 2, the electrolytic capacitor 5 is set such that the depth of the caulking portion 13 is set so that the outer case 2 contacts the capacitor element 1, and the buffer member 18 is provided on the outer periphery of the capacitor element 1. By being provided, the capacitor element 1 can also be fixed by caulking. At this time, the buffer member 18 is interposed between the outer case 2 and the capacitor element 1, and the capacitor element of the caulking portion 13 of the outer case 2. Since the pressing force to 1 is relieved, the stress on the capacitor element 1 can be reduced.
図7を参照しながら、実施例3に係る電解コンデンサについて説明する。実施例3においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 3 will be described with reference to FIG. In the third embodiment, the same reference numerals as those in FIGS. 1 to 5 denote the same members, and duplicate descriptions are omitted.
図7に示すように、実施例3における電解コンデンサ5は、その外周側を実装基板6に向けて取り付けられる横置き型となっている。耐振部材10aには、バンド部11の左右両方の端部から延出される端子部12a、別の端子部12a’を有している。これらの端子部12a、別の端子部12a’の先端部が実装基板6に向けてL字状に屈曲され、実装基板6の貫通孔15を貫通して半田付け16により固定される。また、リード線3の先端部もL字状に屈曲され、実装基板6の貫通孔7を貫通して半田付け16により固定される。
As shown in FIG. 7, the electrolytic capacitor 5 in Example 3 is a horizontal type in which the outer peripheral side is attached to the mounting substrate 6. The vibration-proof member 10 a has a terminal portion 12 a extending from both left and right ends of the band portion 11 and another terminal portion 12 a ′. The tip portions of these terminal portions 12 a and another terminal portion 12 a ′ are bent in an L shape toward the mounting substrate 6, pass through the through holes 15 of the mounting substrate 6, and are fixed by soldering 16. In addition, the leading end portion of the lead wire 3 is also bent in an L shape, passes through the through hole 7 of the mounting substrate 6, and is fixed by soldering 16.
このように、実施例3では、耐振部材10aの両端部がそれぞれの端子部12a、別の端子部12a’により実装基板6に固定されるため、耐振部材10aの端子部12a、別の端子部12a’を介して電解コンデンサ5が実装基板6へ十分な強度で装着される。
Thus, in Example 3, since the both ends of the vibration proof member 10a are fixed to the mounting substrate 6 by the respective terminal portions 12a and the other terminal portions 12a ′, the terminal portions 12a and the other terminal portions of the vibration proof member 10a are fixed. The electrolytic capacitor 5 is attached to the mounting substrate 6 with sufficient strength via 12a ′.
図8及び図9を参照しながら、実施例4に係る電解コンデンサについて説明する。実施例4においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 4 will be described with reference to FIGS. In the fourth embodiment, the same reference numerals as those in FIGS. 1 to 5 indicate the same members, and redundant descriptions are omitted.
前述した実施例1~3では、バンド部11の端部に端子部12が形成されているが、実施例4における耐振部材10bでは、バンド部11の中央部に端子部12bが形成される。耐振部材10bの製造時において、図8(a)に示すように、耐振部材10bのバンド部11の中央部に切断手段を用いて切り込みを入れて切込部Kを形成する。この切込部Kの形状は、端子部12b及び凸部17bの形状となるように形成する。
In the first to third embodiments described above, the terminal portion 12 is formed at the end portion of the band portion 11, but in the vibration-proof member 10b in the fourth embodiment, the terminal portion 12b is formed in the center portion of the band portion 11. At the time of manufacturing the vibration-proof member 10b, as shown in FIG. 8A, a cut portion K is formed by cutting the central portion of the band portion 11 of the vibration-proof member 10b using a cutting means. The shape of the cut portion K is formed to be the shape of the terminal portion 12b and the convex portion 17b.
そして、図8(b)に示すように、バンド部11における切込部Kが形成された部位を展開すると、端子部12b及び凸部17bがバンド部11から外方に向かって延出される。なお、図8(b)では、電解コンデンサ5の外装ケース2に耐振部材10を嵌合させる前に、バンド部11における切込部Kの部位を展開しているが。電解コンデンサ5の外装ケース2に耐振部材10を嵌合させて、加締め部13を形成した後に、バンド部11における切込部Kの部位を展開するようにしてもよい。
Then, as shown in FIG. 8B, when the portion where the cut portion K is formed in the band portion 11 is developed, the terminal portion 12 b and the convex portion 17 b are extended outward from the band portion 11. In FIG. 8B, the portion of the cut portion K in the band portion 11 is developed before the vibration-proof member 10 is fitted to the outer case 2 of the electrolytic capacitor 5. After the vibration-proof member 10 is fitted to the outer case 2 of the electrolytic capacitor 5 and the crimped portion 13 is formed, the portion of the cut portion K in the band portion 11 may be developed.
図9に示すように、実施例4における電解コンデンサ5は、その外周側を実装基板6に向けて取り付けられる横置き型となっている。そして、耐振部材10bのバンド部11の中央部から延出された端子部12bが実装基板6の貫通孔15を貫通して半田付け16により固定される。更に、端子部12b近傍の凸部17bが実装基板6の上面に接触される。
As shown in FIG. 9, the electrolytic capacitor 5 in Example 4 is a horizontal type in which the outer peripheral side is attached to the mounting substrate 6. And the terminal part 12b extended from the center part of the band part 11 of the vibration proof member 10b penetrates the through-hole 15 of the mounting substrate 6, and is fixed by soldering 16. Further, the convex portion 17 b near the terminal portion 12 b is in contact with the upper surface of the mounting substrate 6.
このように、実施例4では、耐振部材10bが、バンド部11の中央部から延出された端子部12bにより実装基板6に固定されるため、耐振部材10bの端子部12bを介して電解コンデンサ5が実装基板6へ十分な強度で装着される。
Thus, in Example 4, since the vibration proof member 10b is fixed to the mounting substrate 6 by the terminal portion 12b extending from the central portion of the band portion 11, an electrolytic capacitor is provided via the terminal portion 12b of the vibration proof member 10b. 5 is attached to the mounting substrate 6 with sufficient strength.
図10を参照しながら、実施例5に係る電解コンデンサについて説明する。実施例5においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 5 will be described with reference to FIG. In the fifth embodiment, the same reference numerals as those in FIGS. 1 to 5 denote the same members, and redundant descriptions are omitted.
図10に示すように、実施例5の耐振部材10cのバンド部11cは、上面側が塞がる有底筒状をなしている。そして、実装基板6を搭載する装置の筐体40における電解コンデンサ5の搭載位置に対応する部位には、耐振部材10cのバンド部11cの上面全体に接触する接触部41が突設されている。また、電解コンデンサ5は、実施例1と同様に、そのリード線3が設けられた端部側が、耐振部材10cによって実装基板6に取り付けられている。
As shown in FIG. 10, the band portion 11c of the vibration-proof member 10c of Example 5 has a bottomed cylindrical shape whose upper surface is closed. A contact portion 41 that protrudes from the entire upper surface of the band portion 11c of the vibration proof member 10c is provided at a position corresponding to the mounting position of the electrolytic capacitor 5 in the housing 40 of the apparatus on which the mounting substrate 6 is mounted. Similarly to the first embodiment, the electrolytic capacitor 5 is attached to the mounting substrate 6 by a vibration-proof member 10c on the end side where the lead wire 3 is provided.
このように、耐振部材10cのバンド部11cの上面全体が筐体40の接触部41に接触されることで、耐振部材10c及び電解コンデンサ5は、実装基板6と筐体40の接触部41との間に挟み込まれるように配置され、外部からの衝撃や振動に十分耐えうるようになる。なお、耐振部材10cのバンド部11cの上面側の有底筒状付近に貫通孔を設け、異常時にコンデンサ本体から放出されるガスを該貫通孔より外部に排出するように構成すると良い。また、耐振部材10cのバンド部11cの上面側が塞がる有底筒状とせず、開口とするように構成し、このバンド部11cの開口部に、筐体40の接触部41を嵌め込み固定してもよい。その際、バンド部11cにおける電解コンデンサ5の外装ケース2の底面よりも上面側にスリット又は穴を開けてもよい。このようにすることで、電解コンデンサ5の外装ケース2の底面に電解コンデンサ5内で発生したガスの放出手段として形成した圧力弁の動作時に、電解コンデンサ5の外部へのガス抜き用の隙間として当該スリット又は穴を利用することができる。
In this way, the entire upper surface of the band portion 11c of the vibration proof member 10c is brought into contact with the contact portion 41 of the housing 40, whereby the vibration proof member 10c and the electrolytic capacitor 5 are connected to the contact portion 41 of the mounting substrate 6 and the housing 40. It is arranged so as to be sandwiched between them so that it can sufficiently withstand external impacts and vibrations. In addition, it is preferable to provide a through hole in the vicinity of the bottomed cylindrical shape on the upper surface side of the band portion 11c of the vibration proof member 10c, and to discharge the gas released from the capacitor main body to the outside through the through hole at the time of abnormality. Even if the upper surface side of the band portion 11c of the vibration proof member 10c is not closed, it is configured as an opening, and the contact portion 41 of the housing 40 is fitted and fixed in the opening portion of the band portion 11c. Good. In that case, you may make a slit or a hole in the upper surface side rather than the bottom surface of the exterior case 2 of the electrolytic capacitor 5 in the band part 11c. In this way, when the pressure valve formed as a means for releasing the gas generated in the electrolytic capacitor 5 on the bottom surface of the outer case 2 of the electrolytic capacitor 5 is operated, a gap for degassing to the outside of the electrolytic capacitor 5 is obtained. The slit or hole can be used.
図12を参照しながら、実施例6に係る電解コンデンサについて説明する。実施例6においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 6 will be described with reference to FIG. In the sixth embodiment, the same reference numerals as those in FIGS. 1 to 5 denote the same members, and duplicate descriptions are omitted.
図12に示すように、耐振部材10dのバンド部11dの端子部12の設けられる端部には、上述した実施例1の凸部17に代えて、高さ方向にスリット状に切り欠かれた溝部27が、周方向に沿って複数個所(本実施例では4カ所)設けられている。
As shown in FIG. 12, the end portion of the band portion 11d of the vibration proof member 10d provided with the terminal portion 12 was cut out in a slit shape in the height direction instead of the convex portion 17 of Example 1 described above. A plurality of groove portions 27 are provided along the circumferential direction (four in this embodiment).
このように、耐振部材10dのバンド部11dの端部に溝部27が設けられていることで、例えばバンド部11dの空回転を防止するため図示しないチャッキング手段等でバンド部11dを押さえつける際に、このバンド部11dの変形が溝部27に吸収されるため、バンド部11dが空回転する等の非固定状態を回避して、良好なチャッキング状態を得ることができる。
Thus, when the groove part 27 is provided at the end of the band part 11d of the vibration proof member 10d, for example, when the band part 11d is pressed by a chucking means (not shown) to prevent idling of the band part 11d. Since the deformation of the band part 11d is absorbed by the groove part 27, a non-fixed state such as idling of the band part 11d can be avoided and a good chucking state can be obtained.
なお、耐振部材10dのバンド部11dの端部には、本実施例の溝部27と併せて上述した実施例1の凸部17が設けられていてもよく、このようにすることで、溝部27の効果と凸部17の効果をいずれも得ることができる。
In addition, the convex part 17 of Example 1 mentioned above together with the groove part 27 of a present Example may be provided in the edge part of the band part 11d of the vibration proof member 10d, By doing in this way, the groove part 27 may be provided. Both the effect of the above and the effect of the convex portion 17 can be obtained.
図13を参照しながら、実施例7に係る電解コンデンサについて説明する。実施例7においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 7 will be described with reference to FIG. In the seventh embodiment, the same reference numerals as those in FIGS. 1 to 5 denote the same members, and a duplicate description is omitted.
図13に示すように、上述した実施例1における加締め部13とは別段に、バンド部11よりも高さ方向に突出した外装ケース2eの部分を単独で加締めて、この加締め部23をコンデンサ素子1に対し押圧してコンデンサ素子1を固定する。
As shown in FIG. 13, separately from the caulking portion 13 in the first embodiment described above, the portion of the exterior case 2 e that protrudes in the height direction from the band portion 11 is caulked alone, and this caulking portion 23. Is pressed against the capacitor element 1 to fix the capacitor element 1.
このように、バンド部11の加締め部13とは別段に、コンデンサ素子1を固定するため加締め部23が外装ケース2eに構成されていることで、バンド部11の固定とコンデンサ素子1の固定とを独立させる構造を採ることができるため、外装ケース、バンド部及びコンデンサ素子の三体以上の部材を一つの加締め部により固定する場合に比べて、各々の部材同士の固定性を高めることができる。なお、コンデンサ素子1を固定するための加締め部23は、図13のように、バンド部11よりも高さ方向に突出した外装ケース2eの部分に限らず、バンド部11に覆われている外装ケース2eの部分であっても良く、また加締め部23は複数個所に設けてもよい。
As described above, the caulking portion 23 is configured in the exterior case 2e to fix the capacitor element 1 separately from the caulking portion 13 of the band portion 11, so that the fixing of the band portion 11 and the capacitor element 1 can be performed. Since it is possible to adopt a structure in which the fixing is independent, the fixing property of each member is improved as compared with the case where three or more members of the exterior case, the band part, and the capacitor element are fixed by one caulking part. be able to. The caulking portion 23 for fixing the capacitor element 1 is not limited to the portion of the exterior case 2e protruding in the height direction from the band portion 11 as shown in FIG. It may be a portion of the outer case 2e, and the caulking portions 23 may be provided at a plurality of locations.
また、加締め部23が形成される高さ位置のコンデンサ素子1の外周には、緩衝部材28が設けられている。このため、加締めによりコンデンサ素子1も固定することができ、その際、緩衝部材28が外装ケース2eとコンデンサ素子1との間に介在され、外装ケース2eの加締め部23のコンデンサ素子1への押圧力が緩和されるため、コンデンサ素子1に作用するストレスを低減することができる。
Further, a buffer member 28 is provided on the outer periphery of the capacitor element 1 at a height position where the caulking portion 23 is formed. For this reason, the capacitor element 1 can also be fixed by caulking. At this time, the buffer member 28 is interposed between the outer case 2e and the capacitor element 1, and the capacitor element 1 of the caulking portion 23 of the outer case 2e is provided. Therefore, the stress acting on the capacitor element 1 can be reduced.
図14及び図15を参照しながら、実施例8に係る電解コンデンサについて説明する。実施例8においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 8 will be described with reference to FIGS. 14 and 15. In the eighth embodiment, the same reference numerals as those in FIGS. 1 to 5 denote the same members, and a duplicate description is omitted.
図14及び図15に示すように、実施例8の耐振部材10fのバンド部11fは、上面側の端部が開放する筒状をなしている。より詳しくは耐振部材10fは、電解コンデンサ5の外装ケース2に嵌合されるバンド部11fとバンド部11fの一端から延出される端子部12とに加え、この端子部12が設けられるバンド部11fの一端とは反対側である上面側の端部に、別の端子部12’を有する。
As shown in FIGS. 14 and 15, the band portion 11 f of the vibration-proof member 10 f of Example 8 has a cylindrical shape with an open end on the upper surface side. More specifically, the vibration-proof member 10f includes a band portion 11f provided with the terminal portion 12 in addition to the band portion 11f fitted to the outer case 2 of the electrolytic capacitor 5 and the terminal portion 12 extending from one end of the band portion 11f. Another terminal portion 12 ′ is provided at the end portion on the upper surface side opposite to one end of the terminal portion.
図14及び図15では別の端子部12’は、端子部12と同様に周方向に等間隔で4個設けられているが、特に個数が限定されるものではなく、また別の端子部12’は、端子部12と異なる個数や間隔で設けられていてもよい。
In FIG. 14 and FIG. 15, four other terminal portions 12 ′ are provided at equal intervals in the circumferential direction like the terminal portion 12, but the number is not particularly limited, and the other terminal portions 12 are not limited. 'May be provided in a different number or interval from the terminal portion 12.
別の端子部12’は、実装基板6を搭載する装置の筐体42に設けられた貫通孔43に嵌入される。このようにすることで、耐振部材10fの端子部12を介して電解コンデンサ5が実装基板6に装着されるうえに、これと反対側に設けた別の端子部12’を介して電解コンデンサ5が筐体に装着され、電解コンデンサ5が実装基板6と筐体42とに挟み込まれるように配設されるため、電解コンデンサ5の耐振動性が向上し、多方向からの衝撃や振動に耐え得る十分な強度を獲得できる。
Another terminal portion 12 ′ is fitted into a through-hole 43 provided in the housing 42 of the device on which the mounting substrate 6 is mounted. By doing so, the electrolytic capacitor 5 is mounted on the mounting substrate 6 via the terminal portion 12 of the vibration-proof member 10f, and the electrolytic capacitor 5 is connected via another terminal portion 12 ′ provided on the opposite side. Is mounted on the housing, and the electrolytic capacitor 5 is disposed so as to be sandwiched between the mounting substrate 6 and the housing 42, so that the vibration resistance of the electrolytic capacitor 5 is improved and it can withstand impacts and vibrations from multiple directions. You can get enough strength.
図14及び図15に示すように、別の端子部12’が設けられるバンド部11fの上面側の端部には、凸部17’が延出されている。このようにすることで、筐体42に対して耐振部材10fが嵌入される場合、凸部17’を利用して電解コンデンサ5と筐体42との間に間隙を設けることができ、電解コンデンサ5と筐体42との間に存在する空気の抜けを良好にすることができる。
As shown in FIGS. 14 and 15, a convex portion 17 ′ is extended to an upper end portion of a band portion 11 f where another terminal portion 12 ′ is provided. By doing so, when the vibration-proof member 10f is inserted into the casing 42, a gap can be provided between the electrolytic capacitor 5 and the casing 42 by using the convex portion 17 ′, and the electrolytic capacitor The escape of air existing between the housing 5 and the housing 42 can be improved.
図14及び図15では凸部17’は、凸部17と同様に周方向に等間隔で4個設けられているが、特に個数が限定されるものではなく、また凸部17’は、凸部17と異なる個数や間隔で設けられていてもよい。
In FIG. 14 and FIG. 15, four convex portions 17 ′ are provided at equal intervals in the circumferential direction like the convex portion 17, but the number is not particularly limited, and the convex portions 17 ′ are convex. It may be provided at a different number or interval from the part 17.
尚、実施例8では、バンド部11fが、その一端に端子部12及び凸部17を有するとともに、一端とは反対側に端子部12’及び凸部17’を有する一体の部材からなっていたが、これに限らず、例えば本発明のバンド部は、特に図示しないが、外装ケース2の一端側に加締められ実装基板6に嵌合する端子部12及び凸部17を有する一方の分割バンド部と、当該一方の分割バンド部とは別体であって、当該一方の分割バンド部から離間して外装ケース2の他端側に加締められ筐体42に嵌合する端子部12’及び凸部17’を有する他方の分割バンド部とからなる、分割された分割構造を有していてもよい。
In Example 8, the band portion 11f was composed of an integral member having the terminal portion 12 and the convex portion 17 at one end thereof, and having the terminal portion 12 ′ and the convex portion 17 ′ on the opposite side to the one end. However, the present invention is not limited to this, for example, the band portion of the present invention is not particularly shown, but is one split band having the terminal portion 12 and the convex portion 17 that are crimped to one end side of the outer case 2 and fitted to the mounting substrate 6. And the one split band part, which are separate from the one split band part and are crimped to the other end side of the outer case 2 and fitted into the housing 42 and You may have the divided | segmented division structure which consists of the other division | segmentation band part which has convex part 17 '.
このようにすることで、電解コンデンサ5の多様な軸方向の長さに対応できるばかりか、バンド部の軽量化を実現でき、また外装ケース2表面の分割バンド部同士の離間した箇所を介した放熱効果を得ることができる。
In this way, not only can the various lengths in the axial direction of the electrolytic capacitor 5 be accommodated, but also the weight of the band portion can be reduced, and the separated band portions on the surface of the exterior case 2 can be separated from each other. A heat dissipation effect can be obtained.
図16を参照しながら、実施例9に係る電解コンデンサについて説明する。実施例9においては、図1ないし図5の符号と同じ符号は同じ部材を示しており、重複する説明は省略する。
The electrolytic capacitor according to Example 9 will be described with reference to FIG. In the ninth embodiment, the same reference numerals as those in FIGS. 1 to 5 denote the same members, and a duplicate description is omitted.
図16(a)に示すように、耐振部材10gのバンド部11gの端子部12gの設けられた端部には、この端子部12gの基端側に一体化して凸部17gが延出されており、更にバンド部11gの当該端部には、一体化した端子部12gの基端側と凸部17gとに架けて、円弧状に湾曲した切込み部45が形成されている。
As shown to Fig.16 (a), the convex part 17g is integrally extended by the base end side of this terminal part 12g in the edge part in which the terminal part 12g of the band part 11g of the vibration proof member 10g was provided. In addition, a cut portion 45 that is curved in an arc shape is formed at the end portion of the band portion 11g so as to span the proximal end side of the integrated terminal portion 12g and the convex portion 17g.
このように、実施例9では、耐振部材10gの端子部12gが設けられた端部に、湾曲状の切込み部45が形成されていることで、この耐振部材10gを備えた電解コンデンサ5を実装基板6に固定する場合、この切込み部45が耐振部材10gと実装基板6との間の密着を避ける空隙部として機能する。
As described above, in Example 9, the curved notch 45 is formed at the end of the vibration proof member 10g where the terminal portion 12g is provided, so that the electrolytic capacitor 5 including the vibration proof member 10g is mounted. When fixing to the board | substrate 6, this notch part 45 functions as a space | gap part which avoids contact | adherence between the vibration proof member 10g and the mounting board | substrate 6. FIG.
したがって図16(b)に示すように、実装基板6の貫通孔15に端子部12gを嵌入して半田付け16をする際に、熱溶融した半田が、耐振部材10gと実装基板6との間で四方八方に噴出せずに貫通孔15から均等に基板表面に這い上がり、空隙部として機能する切込み部45の内側に留保された状態で経時とともに凝固するため、耐振部材10gと実装基板6とが頑強に固定され電解コンデンサ5の防振性が格段に高まるばかりか、噴出した半田が実装基板6表面に付着して基板上の部品同士がショートを起こす虞を回避できる。また切込み部45によって、実装基板6の貫通孔15を凸部17gや耐振部材10gの端部で塞ぐことがないため、貫通孔15内の半田付け16の付着状態を目視確認することができる。
Therefore, as shown in FIG. 16B, when the terminal portion 12 g is inserted into the through hole 15 of the mounting substrate 6 and soldering 16 is performed, the heat-melted solder is interposed between the vibration-proof member 10 g and the mounting substrate 6. Therefore, the vibration-proof member 10g and the mounting substrate 6 are solidified over time in a state in which they crawl evenly from the through holes 15 to the substrate surface without being ejected in all directions and are retained inside the cut portions 45 functioning as gaps. Is firmly fixed and the vibration-proof property of the electrolytic capacitor 5 is remarkably improved, and it is possible to avoid the possibility that the ejected solder adheres to the surface of the mounting substrate 6 and the components on the substrate cause a short circuit. Further, since the through hole 15 of the mounting substrate 6 is not blocked by the projecting portion 17g or the end portion of the vibration proof member 10g by the cut portion 45, the adhesion state of the soldering 16 in the through hole 15 can be visually confirmed.
更に、端子部12gの基端側に湾曲状を成す切込み部45が存在することによって、上記のように半田付けした電解コンデンサ5が振動した際に、例えば端子部の基端が直角に形成される場合と比較して、振動時に端子部の基端に加わる応力が集中せずに、湾曲線に直交する放射方向に応力が分散されるため、振動に起因する電解コンデンサ5の疲労破壊を抑制することができる。
Further, the presence of the curved cut portion 45 on the base end side of the terminal portion 12g allows the base end of the terminal portion to be formed at a right angle when the electrolytic capacitor 5 soldered as described above vibrates. Compared with the case where the stress is applied, the stress applied to the base end of the terminal portion during vibration is not concentrated, and the stress is dispersed in the radial direction perpendicular to the curved line, so that fatigue breakdown of the electrolytic capacitor 5 due to vibration is suppressed. can do.
また、切込み部45は、端子部12gと凸部17gとに架けて形成されていることで、湾曲状を成す切込み部45が、耐振部材10gの端部における凸状部分に形成されるため、耐振部材10gの構造強度を落とさず維持できる。
Further, since the cut portion 45 is formed so as to span the terminal portion 12g and the convex portion 17g, the curved cut portion 45 is formed at the convex portion at the end of the vibration-proof member 10g. The structural strength of the vibration-resistant member 10g can be maintained without dropping.
尚、実施例9では、切込み部45は、耐振部材10gの一体化した端子部12gと凸部17gとに架けて形成されているが、例えば、端子部と凸部とが周方向に離間して別体に設けられ、当該端子部の基端側に、切込み部が前記凸部とは別体に形成されていても構わない。
In the ninth embodiment, the cut portion 45 is formed on the terminal portion 12g and the convex portion 17g integrated with the vibration-proof member 10g. For example, the terminal portion and the convex portion are spaced apart in the circumferential direction. The cut portion may be formed separately from the convex portion on the base end side of the terminal portion.

例えば、実施例1~2では、耐振部材10の端子部12は、実装基板6の貫通孔15に貫通させて半田付けなどによって固定しているが、これに限らず、例えば、図11(a)に示されるように、耐振部材20の端子部22に周方向に切り欠かれた切欠部22aが形成されており、この端子部22を実装基板6の貫通孔15を貫通させてこの切欠部22aを基点に所定角度回動することで、切欠部22aを貫通孔15内の図示しない突部等に嵌合させて実装基板6に固定するようにしてもよい。また例えば、図11(b)に示されるように、耐振部材30の端子部32の基端側に周方向に突出した凸部37を一体化して形成し、この端子部32を実装基板6の貫通孔15に嵌入して凸部37を実装基板6の背面に当接させることで、実装基板6への電解コンデンサ5の高さ位置を調整するようにしてもよい。
For example, in the first and second embodiments, the terminal portion 12 of the vibration-proof member 10 is fixed by soldering or the like through the through-hole 15 of the mounting substrate 6, but is not limited to this, for example, FIG. ), A notch 22a is formed in the terminal portion 22 of the vibration-proof member 20 so as to be cut out in the circumferential direction. The terminal portion 22 is passed through the through hole 15 of the mounting substrate 6 so that the notch The cutout portion 22a may be fitted to a projection (not shown) or the like in the through hole 15 and fixed to the mounting substrate 6 by rotating a predetermined angle about the base point 22a. Further, for example, as shown in FIG. 11 (b), a convex portion 37 protruding in the circumferential direction is integrally formed on the base end side of the terminal portion 32 of the vibration-proof member 30, and the terminal portion 32 is formed on the mounting substrate 6. The height position of the electrolytic capacitor 5 with respect to the mounting substrate 6 may be adjusted by fitting into the through hole 15 and bringing the convex portion 37 into contact with the back surface of the mounting substrate 6.

また、前記実施例では、円筒状の外装ケース2に円筒状の耐振部材10が嵌合されるようになっているが、これに限らず、角型形状等の非円筒形の外装ケースにも適用することができる。なお、角型形状の外装ケースであれば、その角型形状に適合させ、耐振部材の形状を角筒形状にすればよい。
Moreover, in the said Example, although the cylindrical vibration-proof member 10 is fitted to the cylindrical exterior case 2, not only this but non-cylindrical exterior cases, such as a square shape, are also included. Can be applied. In addition, if it is a square-shaped exterior case, it may be adapted to the rectangular shape and the shape of the vibration-proof member may be a rectangular tube.
また、実施例1~5において、円筒状の耐振部材10のバンド部11の内側面に凸部などを設け、外装ケース2にバンド部11を挿入した際に、前記凸部を外装ケース2に当接させ、外装ケース2の所定の位置に耐振部材10を仮固定させてもよい。
Further, in Examples 1 to 5, a convex portion or the like is provided on the inner surface of the band portion 11 of the cylindrical vibration-proof member 10, and when the band portion 11 is inserted into the outer case 2, the convex portion is attached to the outer case 2. The vibration-proof member 10 may be temporarily fixed at a predetermined position of the outer case 2 by abutting.
また、前記実施例では、端子部12や凸部17が予め形成されているバンド部11を外装ケース2に対し加締めることにより、耐振部材10を固定するコンデンサの製造方法について説明したが、これに限らず、例えば特に図示しないが、端子部12や凸部17が未形成のバンド部を外装ケースに対し加締めることにより、耐振部材を固定した後に、当該バンド部に端子部12や凸部17を形成するようにしてもよく、更に、リード線3を基準として、外装ケース2の開口部円周上における端子部12の形成位置を定めて、前記バンド部の一部に端子部12を形成するようにしてもよい。
In the above-described embodiment, the method of manufacturing the capacitor for fixing the vibration-proof member 10 by crimping the band portion 11 on which the terminal portion 12 and the convex portion 17 are formed in advance to the outer case 2 has been described. For example, although not particularly illustrated, after fixing the vibration-proof member by crimping the band portion in which the terminal portion 12 and the convex portion 17 are not formed to the exterior case, the terminal portion 12 and the convex portion are fixed to the band portion. 17 may be formed, and the position where the terminal portion 12 is formed on the circumference of the opening portion of the outer case 2 with respect to the lead wire 3 is determined, and the terminal portion 12 is formed on a part of the band portion. You may make it form.
このようにすることで、バンド部を加締めて耐振部材を固定した後の位置固定されたリード線を基準にして、外装ケースの開口部円周上における端子部の形成位置を定めて、バンド部の一部に端子部を形成することで、コンデンサの取り付けの位置決め精度が格段に向上させることができる。
In this way, the position where the terminal portion is formed on the circumference of the opening portion of the outer case is determined with reference to the position-fixed lead wire after the band portion is swaged and the vibration-proof member is fixed. By forming the terminal part in a part of the part, the positioning accuracy of the capacitor attachment can be remarkably improved.
また、前記実施例においては、実装基板に一つの電解コンデンサ5を配置したが、複数の電解コンデンサ5を近接して配置してもよく、その場合に実施例8のようにバンド部11fの上面側の端部に別の端子部12’を形成し、端子部12’,12’同士が接触するように折り曲げて、端子部12’,12’同士の接触部を接続させて、複数の電解コンデンサ5を一体化させて振動性を向上させてもよい。このとき、端子部12’の表面に半田メッキを施すことで、端子部12’,12’同士の接続に半田を用いることができ、電解コンデンサ5間の狭小な隙間でも端子部12’,12’同士の接続を容易に実現することができる。また、近接して配置した複数の電解コンデンサ5の固定手段として、実施例5のように耐振部材10cをバンド部11cが電解コンデンサ5の上面側を覆うように形成し、バンド部11cの上面全体を複数の電解コンデンサの上面を覆うキャップのようなもので固定して、複数の電解コンデンサを一体化させることで振動性を向上させてもよい。
