【考案の詳細な説明】
本案は電子部品、主として固体電解コンデンサ用のチェ
ーンリード構体の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a chain lead structure for electronic components, mainly solid electrolytic capacitors.
一般に固体電解コンテ゛ンサはタンタル、ニオブ。Solid electrolytic capacitors are generally made of tantalum or niobium.
アルミニウムなどのように弁作用を有する金属粉末を円
柱状に加圧成形し焼結してなるコンデンサペレットに予
め弁作用を有する金属線よりなる陽極リードを植立し、
この陽極リードに第１の外部ノード線を溶接すると共に
、第２の外部リード線をコンデンサペレットの表面に酸
化層、半導体層を介して形成された陰極層に半田付けし
、然る後、その周面を樹脂材にて被覆して構成されてい
る。An anode lead made of a metal wire that has a valve action is planted in advance on a capacitor pellet made by press-molding and sintering metal powder that has a valve action, such as aluminum, into a cylindrical shape.
A first external node wire is welded to this anode lead, and a second external lead wire is soldered to the cathode layer formed on the surface of the capacitor pellet via an oxide layer and a semiconductor layer. It is constructed by covering the peripheral surface with a resin material.
特に第１及び第２の外部リード線は例えば第１図に示す
ように金属板よりなる帯状の支持部材Ａに複数のリード
線Ｂを一定のピッチ間隔にて溶接してなるチェーンリー

定されたコンデンサペレットに並接し、それのリード線
Ｂをコンデンサペレットの各電極に接続後、支持部材Ａ
よりリード線Ｂの所定部分を切離することによって引出
されているために量産性の点で優れている。In particular, the first and second external lead wires are made of a chain lead structure in which a plurality of lead wires B are welded at regular pitch intervals to a band-shaped support member A made of a metal plate, as shown in FIG. The support member A is placed in parallel with the capacitor pellets fixed in advance to a band-shaped metal plate at a constant pitch, and after connecting its lead wire B to each electrode of the capacitor pellet.
Since the lead wire B is drawn out by cutting off a predetermined portion thereof, it is excellent in terms of mass productivity.
ところで、近年安価にしてかつ高品質のコンデンサの要
求が強くなっており、製造工程の合理化などによるコス
トの低減が計られている。Incidentally, in recent years there has been a strong demand for inexpensive and high-quality capacitors, and efforts are being made to reduce costs by streamlining the manufacturing process.
その−環としてチェーンリード構体における支持部材Ａ
を金属材より安価な紙材に変更する試みがなされている
。- Support member A in the chain lead structure as a ring
Attempts are being made to replace metal with paper, which is cheaper.
即ち、第２図〜第３図に示すようにプレスポードよりな
る支持部材Ｃにリード線Ｂを一定のピッチ間隔にて載置
し、リード線Ｂの上端を支持部材Ｃの上端縁の裏側に屈
曲することによって構成されている。That is, as shown in FIGS. 2 and 3, lead wires B are placed on a support member C made of presspods at regular pitch intervals, and the upper ends of the lead wires B are bent behind the upper edge of the support member C. It consists of:
しかし乍ら、リード線Ｂは上端部のみが支持部材Ｃに固
定されている関係で、製造工程においてリード線Ｂに横
方向に押圧力などが作用すると、リード線Ｂの上端固定
部を支点として左右いずれかに回転し、リード線Ｂの下
端部におけるピッチ間隔が乱れてしまう。However, since only the upper end of the lead wire B is fixed to the supporting member C, if a pressing force is applied to the lead wire B in the lateral direction during the manufacturing process, the upper end of the lead wire B will be used as a fulcrum. The lead wire B rotates either left or right, and the pitch interval at the lower end of the lead wire B becomes disordered.
このために、リード線Ｂのコンデンサペレットの各電極
への接続作業性が著しく低下するという欠点か゛ある。This has the disadvantage that the workability of connecting the lead wire B to each electrode of the capacitor pellet is significantly reduced.
本案はこのような点に鑑み、支持部材に固定されたリー
ド線に横方向の押圧力などが作用してもリード線の支持
部材上での回転を防止してリード線のピッチ間隔の乱れ
を軽減しうる電子部品のチェーンリード構体を提供する
もので、以下実施例について説明する。In view of these points, this proposal prevents the lead wires from rotating on the support member even if a lateral pressing force is applied to the lead wires fixed to the support member, thereby preventing the pitch interval of the lead wires from being disturbed. The present invention provides a chain lead structure for electronic components that can be reduced in weight, and examples thereof will be described below.

、４は孔３の形成によって裏側に突出された絶縁材の突
出部である。In FIGS. 4 and 5, 1 is a band-shaped support member made of an insulating material such as presspod or fiber; 2, 2 are narrow support arms formed at both ends of the support member; 2a, 2a;
3 is a position regulating portion, 3 is a hole formed at a constant pitch, and 4 is a protrusion of an insulating material that protrudes to the back side due to the formation of the hole 3.
５はリード線で、６は支持部材１の孔３にほぼコ字状の
屈曲状態で凹入係止された凹入部、７は支持部材１の上
端部を挟持するために、支持部材の表側より裏側に屈曲
された屈曲部である。5 is a lead wire, 6 is a recessed part which is bent into the hole 3 of the supporting member 1 in a substantially U-shaped state, and 7 is a recessed part on the front side of the supporting member 1 for holding the upper end of the supporting member 1. This is a bent part that is bent further to the back side.
次にリード線５の支持部材１への係止方法について説明
する。Next, a method of locking the lead wire 5 to the support member 1 will be explained.
まず、第６図ａに示すように支持部材１の上に直線状の
リード線５を載置すると共に、リード線５の上方に押圧
体５を配置する。First, as shown in FIG. 6a, the linear lead wire 5 is placed on the support member 1, and the pressing body 5 is placed above the lead wire 5.
尚、押圧体８の下端部には断面逆Ｖ字状の凹部９が形成
されており、両端部はカッタ一部１０．１０を構成して
いる。A recess 9 having an inverted V-shaped cross section is formed at the lower end of the pressing body 8, and both ends constitute cutter portions 10 and 10.
次に同図すに示すように押圧体８を下降させカッタ一部
１０．１０を支持部材１に突き差し、支持部材１に切れ
目を入れる。Next, as shown in the figure, the pressing body 8 is lowered and the cutter portions 10 and 10 are inserted into the support member 1 to make a cut in the support member 1.
さらに押圧体８を下降させるとそれの凹部９にてリード
線５が押圧される。When the pressing body 8 is further lowered, the lead wire 5 is pressed by the recess 9 of the pressing body 8.
そしてさらに押圧体８を下降されると、同図Ｃに示すよ
うにリード線５はほは゛コ字状の屈曲状態で支持部材１
に凹入される。Then, when the pressing body 8 is further lowered, the lead wire 5 is bent in a U-shape as shown in FIG.
It is indented in.
これと同時にノード線５の凹入された部分の支持部材が
裏側に突出４される。At the same time, the supporting member of the recessed portion of the node line 5 is projected 4 to the back side.
次にリード線５の上端を支持部材１の裏側に屈曲し、支
持部材１の上端部を挟持して組立を完了する。Next, the upper end of the lead wire 5 is bent to the back side of the support member 1, and the upper end of the support member 1 is clamped to complete the assembly.
このようにリード線５はそれの一部分が支持部材１に凹
入係止されていると同時に上端部が挾持されているので
、リード線５に横方向の押圧力などが作用してもリード
線５は凹入部６と孔３の嵌合係止によって横方向に回転
できず、従ってリード線５の回転によるピッチ間隔の乱
れは生じない。In this way, a part of the lead wire 5 is recessed and locked in the support member 1, and at the same time, the upper end is clamped, so that even if a lateral pressing force is applied to the lead wire 5, the lead wire 5 cannot be rotated in the lateral direction due to the engagement and locking between the recessed portion 6 and the hole 3, and therefore, the pitch interval is not disturbed by the rotation of the lead wire 5.
又、リード線５の凹入部６は強制的に支持部材１に凹入
されているので、押圧体８による凹入部分を除く凹入部
分はリード線５と支持部材１との保合が強固に行われて
いて、リード線５の固着性を向上できる。Further, since the recessed part 6 of the lead wire 5 is forcibly recessed into the support member 1, the lead wire 5 and the support member 1 are firmly connected in the recessed part except for the recessed part by the pressing body 8. This is done to improve the adhesion of the lead wire 5.
通常、チェーンリード構体は例えば第７図〜第９図に示
すように他のチェーンリード構体１１と並接して用いら
れることか゛多い。Normally, the chain lead structure is often used in parallel with another chain lead structure 11, as shown in FIGS. 7 to 9, for example.
尚、チェーンリード構体１１は金属板１２にリード線１
３を一定のピッチ間隔で溶接して構成されている。Incidentally, the chain lead structure 11 has a lead wire 1 on a metal plate 12.
3 are welded at regular pitch intervals.

ａ、２ａを載置して整列治具１４のスリット１５に挿入
される。Both chain node structures are overlapped at their central portions, and position regulating portions 2 of the support arms 2, 2 are attached to the upper edge of the metal plate 12 at both ends.
a and 2a are placed and inserted into the slit 15 of the alignment jig 14.
このような場合、支持部材１の両端部を巾の狭い支持腕
部２，２とすることによって両チェーンリード構体相互
間の位置規制を確実に行うことができる上、整列治具１
４に挿入した場合、支持腕部２゜２が若干湾曲するため
にスリット１５に裕度があってもがたつくことがなく、
支持部材が整列治具１４より離脱することがない。In such a case, by forming both ends of the support member 1 into narrow support arms 2, 2, the positions of both chain lead structures can be reliably regulated, and the alignment jig 1 can be reliably controlled.
4, the support arm 2°2 is slightly curved so that it does not shake even if the slit 15 has a margin.
The support member does not come off from the alignment jig 14.
従って、作業時の修正を必要とせず、作業能率を著しく
改善できる。Therefore, no correction is required during work, and work efficiency can be significantly improved.
又、チェーンリード構体１１上に本案に係るチェーンリ

に同時にエージングすることができる。Furthermore, if the chain lead structure according to the present invention is superimposed on the chain lead structure 11, each lead wire 5, 13 is insulated and separated, so when aging is performed by connecting a condenser pellet to the lower end of the lead wires 5, 13. , individual capacitor pellets can be aged separately and simultaneously for multiple capacitor pellets.
しかも、リード線５の上端はチェーンリード構体１１よ

ージングの作業能率を著しく高めることができる。Furthermore, since the upper end of the lead wire 5 protrudes above the chain lead structure 11, the bent portion 7 can be used as an aging terminal, especially when a metal plate or a metal foil plate having a fuse function is used as the power supply side terminal. An electrical connection can be obtained simply by placing the bent portion 7 on the lower side, and the aging work efficiency can be significantly improved.
