Description

本発明は、電子部品およびその部品ホルダーに関し、さらに詳しく言えば、プレスフィット端子を有する電子部品およびその部品ホルダーに関するものである。 The present invention relates to electronic components and component holders thereof, and more specifically to electronic components having press-fit terminals and component holders thereof.

部品素子が内蔵されている外装ケースの封口部から一対のリード端子が同一方向に引き出されているリード同一方向型（ディスクリート型とも言う）の電子部品、例えばアルミニウム電解コンデンサでは、回路基板に対して表面実装可能とするため、外装ケースの封口部側に一対のリード挿通孔を有する合成樹脂製の座板を装着し、そのリード挿通孔を通して座板の底面側に引き出されたリード端子を互いに離反する方向に折り曲げてチップ型とすることが行われている（例えば、特許文献１，２参照）。 In electronic components with the same lead direction (also called discrete type) in which a pair of lead terminals are pulled out in the same direction from the sealing part of the outer case in which the component element is built, such as aluminum electrolytic capacitors, a seat plate made of synthetic resin with a pair of lead insertion holes is attached to the sealing part side of the outer case so that the lead terminals pulled out through the lead insertion holes to the bottom side of the seat plate are bent in directions away from each other to form a chip type (see, for example, Patent Documents 1 and 2).

通常、この種のチップ型電子部品は、リフローはんだ付け法によって回路基板にはんだ付けされるが、まず、その設備やメンテナンスに多大なコストがかかる。また、はんだ槽の温度管理やはんだの品質管理に厳密さが要求され、ともするとはんだ付け不良が出やすい。 Typically, these types of chip-type electronic components are soldered to circuit boards using the reflow soldering method, but first of all, the equipment and maintenance required are very costly. In addition, strict control of the solder bath temperature and solder quality is required, which can easily lead to soldering defects.

次に、図１ないし図７により、本発明のいくつかの実施形態について説明するが、本発明はこれらの実施形態に限定されるものではない。 Next, several embodiments of the present invention will be described with reference to Figures 1 to 7, but the present invention is not limited to these embodiments.

先ず、図１ないし図３を参照して、本発明による電子部品１は、部品本体１０と、部品本体１０に取り付けられる部品ホルダー２０とを備えている。 First, referring to Figures 1 to 3, the electronic component 1 according to the present invention comprises a component body 10 and a component holder 20 attached to the component body 10.

部品本体１０は、外装ケース１１を備えている。部品本体１０を例えばアルミニウム電解コンデンサとすると、外装ケース１１にはアルミニウム製で一端が開放された筒状体（多くの場合、円筒体）が用いられ、外装ケース１１内には部品素子としてのコンデンサ素子１２が収納される。 The component body 10 includes an exterior case 11. If the component body 10 is, for example, an aluminum electrolytic capacitor, the exterior case 11 is an aluminum tubular body (usually a cylindrical body) with one end open, and a capacitor element 12 is housed within the exterior case 11 as a component element.

詳しくは図示しないが、コンデンサ素子１２は、ともにアルミニウムからなる陽極箔と陰極箔とを電気絶縁性のセパレータを介して渦巻き状に巻回することにより作成され、陽極箔にはリード端子１３ａが取り付けられ、同じく、陰極箔にもリード端子１３ｂが取り付けられる。 Although not shown in detail, the capacitor element 12 is made by spirally winding an anode foil and a cathode foil, both made of aluminum, with an electrically insulating separator between them, and a lead terminal 13a is attached to the anode foil, and a lead terminal 13b is also attached to the cathode foil.

リード端子１３ａ，１３ｂにはタブ端子が用いられ、その各々は外部引出リード線１３１ａ，１３１ｂを備えている。リード端子１３ａ，１３ｂは同一構成であるため、それらを区別する必要がない場合には、総称としてリード端子１３と言う。また、外部引出リード線１３１ａ，１３１ｂも区別する必要がない場合には、総称として外部引出リード線１３１と言う。 Tab terminals are used for the lead terminals 13a and 13b, and each of them is equipped with an external lead wire 131a, 131b. Because the lead terminals 13a and 13b have the same configuration, when there is no need to distinguish between them, they are collectively referred to as the lead terminal 13. Furthermore, when there is no need to distinguish between the external lead wires 131a and 131b, they are collectively referred to as the external lead wire 131.

図２の断面図に示すように、外装ケース１１の開口部は、封口体１４により気密的に閉じられている。通常、封口体１４はブチルゴム等のゴム製である。封口体１４には、外部引出リード線１３１（１３１ａ，１３１ｂ）を外部に引き出すための一対のリード端子挿通孔が設けられている。 As shown in the cross-sectional view of FIG. 2, the opening of the exterior case 11 is hermetically closed by a sealing body 14. Typically, the sealing body 14 is made of rubber such as butyl rubber. The sealing body 14 has a pair of lead terminal insertion holes for leading the external lead wires 131 (131a, 131b) to the outside.

部品ホルダー２０は、合成樹脂好ましくは耐熱性の合成樹脂からなる。図５および図６を参照して、部品ホルダー２０は、四角形（好ましくは正四角形）に形成された台座部２１０を備えている。台座部は座板部と呼ばれてもよい。 The component holder 20 is made of synthetic resin, preferably heat-resistant synthetic resin. With reference to Figures 5 and 6, the component holder 20 has a base portion 210 formed in a quadrangle (preferably a regular quadrangle). The base portion may also be called a seat plate portion.

図５（ｅ）の断面図において、台座部２１０は、その上面側に部品本体１０が搭載される搭載部２２０が設けられ、底面（下面）側に図示しない回路基板に対する実装部２３０が設けられている。 In the cross-sectional view of FIG. 5(e), the base portion 210 has a mounting portion 220 on the upper surface thereof on which the component body 10 is mounted, and a mounting portion 230 on the bottom surface (lower surface) thereof for mounting to a circuit board (not shown).

台座部２１０の上面（搭載部２２０の部品搭載面）には、外装ケース１１の封口部側の一端が浅く嵌合する円形の凹部２１１が形成されている。凹部２１１の中央部分には、外部引出リード線１３１ａ，１３１ｂが挿通されるリード線挿通孔２１２，２１２が一対として穿設されている。 A circular recess 211 is formed on the upper surface of the base 210 (the component mounting surface of the mounting portion 220) into which one end of the sealing portion of the exterior case 11 fits shallowly. A pair of lead wire insertion holes 212, 212 through which the external lead wires 131a, 131b are inserted are drilled in the center of the recess 211.

また、搭載部２２０には、搭載される部品本体１０を保持する部品保持部２１３が設けられている。この実施形態において、部品保持部２１３は、部品本体１０の外装ケース１１が密接に嵌合するように台座部２１０の四隅に立設された４つの保持アーム２１３ａ～２１３ｄからなる。 The mounting section 220 is also provided with a component holding section 213 that holds the component body 10 to be mounted. In this embodiment, the component holding section 213 is made up of four holding arms 213a to 213d that are erected at the four corners of the base section 210 so that the exterior case 11 of the component body 10 fits closely to it.

他の例として、部品保持部２１３は、外装ケース１１の外面に沿って延びる対向的に配置された少なくとも２つの保持アーム、例えば２１３ａと２１３ｃの組合せもしくは２１３ｂと２１ｄの組合せであってもよい。また、外装ケース１１が密接に嵌合する円筒体であってもよい。部品本体１０は部品保持部２１３内で接着剤等により固定されてもよい。 As another example, the component holding portion 213 may be at least two holding arms arranged opposite each other and extending along the outer surface of the outer case 11, such as a combination of 213a and 213c or a combination of 213b and 213d. It may also be a cylindrical body into which the outer case 11 fits closely. The component body 10 may be fixed inside the component holding portion 213 with an adhesive or the like.

特に図６（ｂ）を参照して、底面側の実装部２３０には、一方のリード端子１３ａの外部引出リード線１３１ａと電気的に接続される第１端子部２０１と、他方のリード端子１３ｂの外部引出リード線１３１ｂと電気的に接続される第２端子部２０２とが設けられている。 Referring particularly to FIG. 6(b), the mounting portion 230 on the bottom side is provided with a first terminal portion 201 electrically connected to the external lead wire 131a of one lead terminal 13a, and a second terminal portion 202 electrically connected to the external lead wire 131b of the other lead terminal 13b.

例えば、第１端子部２０１が陽極側で、第２端子部２０２が陰極側であり、これら端子部２０１，２０２は、台座部２１０の４辺のうちの対向する２辺２１０Ｌ，２１０Ｒに配置されている。 For example, the first terminal 201 is the anode side and the second terminal 202 is the cathode side, and these terminals 201, 202 are arranged on two opposing sides 210L, 210R of the four sides of the base 210.

本発明では、図示しない回路基板に対する差し込み端子としてプレスフイット端子が用いられる。プレスフイット端子とは、回路基板のスルーホールに挿入される端子にバネ特性を持たせ、そのスルーホールの孔径よりも大きな幅を有する端子をスルーホールに圧入することにより、端子の弾性変形による圧力にてスルーホール内めっきとの接触を維持する端子である。プレスフイット端子には、ニードルアイ端子型、アクション端子型、Σ端子型等があるが、特に制限はない。 In the present invention, a press-fit terminal is used as a plug-in terminal for a circuit board (not shown). A press-fit terminal is a terminal that is inserted into a through-hole of a circuit board and has spring properties. The terminal is pressed into the through-hole with a width larger than the diameter of the through-hole, and the pressure caused by the elastic deformation of the terminal maintains contact with the plating inside the through-hole. There are various types of press-fit terminals, including needle-eye terminals, action terminals, and Σ terminals, but there are no particular limitations.

本発明の好ましい態様によると、第１端子部２０１は２つのプレスフイット端子２３１ａ，２３１ｂを備え、同様に、第２端子部２０２も２つのプレスフイット端子２３１ｃ，２３１ｄを備えている。これらプレスフイット端子２３１ａ，２３１ｂ，２３１ｃおよび２３１ｄは同一構成であるため、区別する必要がない場合には、総称としてプレスフイット端子２３１と言う。 According to a preferred embodiment of the present invention, the first terminal portion 201 includes two press-fit terminals 231a and 231b, and similarly, the second terminal portion 202 includes two press-fit terminals 231c and 231d. Since the press-fit terminals 231a, 231b, 231c, and 231d have the same configuration, they are collectively referred to as press-fit terminals 231 when there is no need to distinguish between them.

この実施形態において、第１端子部２０１のプレスフイット端子２３１ａ，２３１ｂは台座部２１０のリード線挿通孔２１２，２１２を通る中心線Ｘ－Ｘ（図５（ａ）参照）から等距離に配置されている。同じく、第２端子部２０２のプレスフイット端子２３１ｃ，２３１ｄも台座部２１０のリード線挿通孔２１２，２１２を通る中心線Ｘ－Ｘから等距離に配置されている。 In this embodiment, the press-fit terminals 231a, 231b of the first terminal portion 201 are arranged equidistantly from the center line X-X (see FIG. 5(a)) passing through the lead wire insertion holes 212, 212 of the base portion 210. Similarly, the press-fit terminals 231c, 231d of the second terminal portion 202 are also arranged equidistantly from the center line X-X passing through the lead wire insertion holes 212, 212 of the base portion 210.

また、第１端子部２０１のプレスフイット端子２３１ａ，２３１ｂを含む第１平面Ｐ１と、第２端子部２０２のプレスフイット端子２３１ｃ，２３１ｄを含む第２平面Ｐ２は互いに平行であるが、回路基板への逆差し（陽極と陰極の入れ違い）を防止するため、一方のプレスフイット端子２３１ａ，２３１ｂの間隔ｄ１と、他方のプレスフイット端子２３１ｃ，２３１ｄの間隔ｄ２をｄ１≠ｄ２としている。 The first plane P1 including the press-fit terminals 231a, 231b of the first terminal portion 201 and the second plane P2 including the press-fit terminals 231c, 231d of the second terminal portion 202 are parallel to each other, but to prevent reverse insertion (mixing up the anode and cathode) onto the circuit board, the distance d1 between the press-fit terminals 231a, 231b on one side and the distance d2 between the press-fit terminals 231c, 231d on the other side are d1 ≠ d2.

また、目視でも極性が判別できるようにするため、上記間隔ｄ１と上記間隔ｄ２の差の絶対値|ｄ１－ｄ２｜は１ｍｍ以上であることが好ましい。なお、逆差し防止の他の方法として、プレスフイット端子２３１ａ，２３１ｂを含む第１平面Ｐ１とプレスフイット端子２３１ｃ，２３１ｄを含む第２平面Ｐ２を非平行としてもよい。 In order to make it possible to visually distinguish the polarity, it is preferable that the absolute value of the difference between the above-mentioned interval d1 and the above-mentioned interval d2, |d1-d2|, is 1 mm or more. As another method for preventing reverse insertion, the first plane P1 including the press-fit terminals 231a and 231b and the second plane P2 including the press-fit terminals 231c and 231d may be made non-parallel.

さらに、目視でも極性が判別できるようにするため、第１端子部２０１側（陽極側）の保持アーム２１３ａ，２３１ｄと、第２端子部２０２側（陰極側）の保持アーム２１３ｂ，２３１ｃの高さを異ならせるようにしてもよい。本実施形態では、陽極側の保持アーム２１３ａ，２３１ｄの方を陰極側の保持アーム２１３ｂ，２３１ｃよりも高くしている。 Furthermore, in order to make it possible to visually distinguish the polarity, the heights of the holding arms 213a, 231d on the first terminal 201 side (anode side) and the holding arms 213b, 231c on the second terminal 202 side (cathode side) may be made different. In this embodiment, the holding arms 213a, 231d on the anode side are made higher than the holding arms 213b, 231c on the cathode side.

次に、図３および図４を参照して、第１端子部２０１のプレスフイット端子２３１ａ，２３１ｂは台座部２１０に埋設されている中継端子板２３４により連結されており、同様に、第２端子部２０２のプレスフイット端子２３１ｃ，２３１ｄも台座部２１０に埋設されている中継端子板２３４により連結されている。 Next, referring to Figures 3 and 4, the press-fit terminals 231a and 231b of the first terminal portion 201 are connected by a relay terminal plate 234 embedded in the base portion 210, and similarly, the press-fit terminals 231c and 231d of the second terminal portion 202 are also connected by a relay terminal plate 234 embedded in the base portion 210.

中継端子板２３４は、その一部分（上記中心線Ｘ－Ｘに沿った部分）が台座部２１０の底面側に露出しており、そこにリード端子１３（１３ａ，１３ｂ）の外部引出リード線１３１（１３１ａ，１３１ｂ）が接続されている。その接続方法は、はんだ付けや溶接等であってよい。 A portion of the relay terminal board 234 (the portion along the center line X-X) is exposed on the bottom side of the base portion 210, and the external lead wires 131 (131a, 131b) of the lead terminals 13 (13a, 13b) are connected to the portion. The connection may be by soldering, welding, or the like.

この電子部品１を組み立てるには、部品本体１０をその外部引出リード線１３１ａ，１３１ｂをリード線挿通孔２１２，２１２に挿通しながら部品ホルダー２０の搭載部２２０に搭載した後、外部引出リード線１３１ａ，１３１ｂを互いに離れる方向にほぼ９０゜折り曲げて中継端子板２３４，２３４にはんだ付けや溶接等により接続する。 To assemble this electronic component 1, the component body 10 is mounted on the mounting portion 220 of the component holder 20 while its external lead wires 131a, 131b are inserted through the lead wire insertion holes 212, 212, and then the external lead wires 131a, 131b are bent approximately 90 degrees away from each other and connected to the relay terminal boards 234, 234 by soldering, welding, or the like.

回路基板に実装するには、プレスフイット端子２３１（２３１ａ～２３１ｄ）を回路基板に穿設されているスルーホール内に圧入すればよい。これにより、はんだレスの電気的な接続が可能になる。 To mount the device on a circuit board, press-fit terminals 231 (231a to 231d) are simply pressed into through holes drilled in the circuit board. This allows for a solderless electrical connection.

このように、プレスフイット端子によれば、はんだレスの電気的な接続が可能になるが、より接続の信頼性等を高める場合、例えばフローはんだ付けもしくはリフローはんだ付けが併用されることがある。 In this way, press-fit terminals allow for solderless electrical connections, but to further increase the reliability of the connection, for example, flow soldering or reflow soldering may be used in combination.

その際の熱によって保持アーム２１３に反り等の変形が生じないようにするため、図７に示すように、各保持アーム２１３の間（２１３ａと２１３ｂ，２１３ｂと２１３ｃ，２１３ｃと２１３ｄおよび２１３ｄと２１３ａの各間）に補強板２１４を一体に形成することが好ましい。 In order to prevent deformation such as warping of the holding arms 213 due to the heat generated at that time, it is preferable to form reinforcing plates 214 integrally between each holding arm 213 (between 213a and 213b, 213b and 213c, 213c and 213d, and 213d and 213a) as shown in FIG. 7.
