この考案はラグ端子付プリント基板、特に半田浸漬法に
よりプリント配線されたプリント基板と他の基板に固設
したリード支柱とを電気機械的に結合するに好適なラグ
端子の構造に関する。[Detailed description of the invention] This invention is a printed circuit board with lug terminals, particularly a lug terminal suitable for electromechanically connecting a printed circuit board printed with solder dipping and a lead support fixed to another board. Regarding the structure of
通信機器等の組立構造では複数の配線基板をサブアッセ
ンブルした後、相互に電気機械的に結合して取付部品の
実装密度を高めて小型化を計ることが行なわれている。BACKGROUND ART In the assembly structure of communication equipment, etc., a plurality of wiring boards are sub-assembled and then electromechanically coupled to each other to increase the mounting density of attached parts and to reduce the size.
例えば、各配線基板としてプリント基板を互に結合する
場合やチューナのようにシャーシベースとプリント基板
との結合がある。For example, there is a case where printed circuit boards are connected to each other as each wiring board, or a case where a chassis base and a printed circuit board are connected as in a tuner.
このような結合構造は、通常一方の基板に固定されたリ
ード支柱を他方の基板に設けたはとめ端子に挿通し半田
固着したり、それぞれにはとめ端子を設けた複数のプリ
ント基板を各はとめ端子を挿通したリード支柱を用いて
半田固着している。Such a bonding structure usually involves inserting and soldering a lead post fixed to one board into a grommet terminal on the other board, or connecting multiple printed circuit boards each with a grommet terminal. It is fixed by soldering using a lead post with a stop terminal inserted through it.
そして、プリント基板のサブアッセンブルは半田浸漬法
で半田付けし、リード支柱とはとめ端子間の接続は手半
田で行なわれる。The subassembly of the printed circuit board is soldered using the solder dipping method, and the connection between the lead support and the eyelet terminal is made by hand soldering.
しかし、従来のはとめ端子構造では半田浸漬に際しては
とめ半田埋まり、すなわち、はとめ端子の穴づまりが生
じてリード支柱の挿通を不可能にすることがあった。However, in the conventional eyelet terminal structure, when the eyelet terminal is dipped in solder, the eyelet solder may become buried, that is, the hole of the eyelet terminal may become clogged, making it impossible to insert the lead support.
このような半田埋まりはその補修に多大の工数を要し組
立作業にとって重大な障害となっていた。Such solder filling requires a large amount of man-hours to repair, and is a serious hindrance to assembly work.
特に、多数のはとめ端子を連続的に並べてはとめ穴を比
較的小径にする場合には半田の表面張力が増大して穴づ
まりを生じ易くしている。In particular, when a large number of eyelet terminals are arranged in succession to make the eyelet holes relatively small in diameter, the surface tension of the solder increases, making the holes more likely to become clogged.
従って、本考案の目的は上記に鑑み提案されたものであ
り、改良されたラグ付きプリント基板を提供することに

対向する脚部を折曲形威し、更に脚部先端を折曲する。That is, each press piece is separated from a punched body that has been press-formed into a predetermined shape while continuing on a metal sheet plate, and then the opposing legs are bent and the tips of the legs are bent.
このような金属板ラグ端子はその両脚部を弾性変形して
プリント基板のスルーホールに挿着され、その先端側で
プリント基板の導電ランドと半田浸漬法で半田付けされ
る。Such a metal plate lug terminal is inserted into a through hole of a printed circuit board by elastically deforming both legs, and its tip side is soldered to a conductive land of the printed circuit board by a solder dipping method.
ここで、ラグ端子の基部はスルーホールより大きく形威
しラグ端子の挿着を容易にし脚部の折曲先端と共にプリ
ント基板上での仮保持に役立てられる。Here, the base of the lug terminal is larger in shape than the through hole to facilitate insertion and attachment of the lug terminal, and to be used together with the bent ends of the legs to temporarily hold the lug terminal on the printed circuit board.
また、プリント基板の導電ランドはスルーホールの周辺
部分のうちラグ端子の脚部が位置する部分にのみ延在さ
せることで導電ランド間の半田ブリッヂやそれによるス
ルーホール穴づまりの防止になる。Further, by extending the conductive lands of the printed circuit board only to the portions around the through holes where the leg portions of the lug terminals are located, solder bridges between the conductive lands and clogging of the through holes due to the solder bridges can be prevented.
一方、本考案の別の観点において、前述するようなラグ
端子付プリント基板は、別の基板に固設したリード支柱
、例えば、シールドケースに取付けた貫通コンデンサの
リードと電気的機械的に結合される。On the other hand, in another aspect of the present invention, a printed circuit board with lug terminals as described above is electrically and mechanically coupled to a lead support fixed to another board, for example, a feedthrough capacitor lead attached to a shield case. Ru.
リード支柱はこれをラグ端子の基部の中央透孔に挿通し
ラグ端子と手半田等により半田付けされる。The lead support is inserted into the central through hole at the base of the lug terminal and soldered to the lug terminal by hand soldering or the like.
従って、半田埋まりかなく配線基板間をリード支柱で結
合し得るラグ端子付プリント基板が簡単な構造と組立作
業により得られる。Therefore, a printed circuit board with lug terminals capable of connecting wiring boards with lead supports without being filled with solder can be obtained with a simple structure and assembly work.

２図参照）、プリント基板２を半田浸漬処理するとき、
第３図に示すように、スルーホール７に半田槽８のデツ
プ用半田が゛ない上って半田埋よりとなる。Normally, the eyelet terminal 1 is located around the entire circumference of the through hole 7 on the conductive land 6 side of the printed circuit board 2 (see Fig. 2), so when the printed circuit board 2 is subjected to solder dipping,
As shown in FIG. 3, there is no solder for the depth in the solder tank 8 in the through hole 7, and the solder is buried therein.
このような半田埋まりのしたはとめ端子１はリード支柱
４の挿通を不能にするので第１図の組立体に利用できず
再度加熱して穴づまりの半田を除去しなければならない
。Such a solder-filled eyelet terminal 1 makes it impossible to insert the lead support 4, and therefore cannot be used in the assembly shown in FIG. 1, and must be heated again to remove the solder stuck in the hole.
また、このような半田埋まりを防ぐため、半田の付かな
い詰物の使用や半田レジストの利用があったが、作業性
を著しるしく低下させ付加部品や付加工程を必要とする
ので製造コストの上昇を招いていた。Additionally, in order to prevent such solder filling, non-solder fillers and solder resists have been used, but this significantly reduces workability and requires additional parts and processes, which increases manufacturing costs. was inviting.

第５図に示すように、ラグ端子１０は中央に透孔１１を
形成した基部１２に先端１３を折曲した脚部１４を対向
して設けた金属板から戒る。As shown in FIG. 5, the lug terminal 10 consists of a metal plate having a base 12 having a through hole 11 formed in the center and legs 14 having bent tips 13 facing each other.
このラグ端子１０は好ましくは、第６図に示すような金
属シート板１５を所定形状にプレス加工して互に連絡し
た打抜片１６を、その連結部分１７から切り離して新曲
加工されて作られる。This lug terminal 10 is preferably made by pressing a metal sheet plate 15 into a predetermined shape as shown in FIG. .
ここで１８は切り離しを容易にする孔である。Here, 18 is a hole that facilitates separation.
一方、プリント基板２０は、第７図に示すように、ラグ
端子の対向する脚部１４を挿通する略長方形のスルーホ

る導電ランド２２を形成している。On the other hand, as shown in FIG. 7, the printed circuit board 20 has a substantially rectangular through hole 21 through which the opposing legs 14 of the lug terminals are inserted, and a conductive land 22 extending around the through hole 21. ing.
スルーホール２１の寸法はラグ端子１０の基部１２の寸
法より小さく形成することによりラグ端子１０のプリン
ト基板への挿着の容易化が計られる。By forming the size of the through hole 21 smaller than the size of the base 12 of the lug terminal 10, the lug terminal 10 can be easily inserted into the printed circuit board.
また、対向する脚部１４の弾性と折曲する先端１３との
利用によりラグ端子１０は半田固着されるまでの間プリ
ント基板２０上で仮係止され得る。Further, by utilizing the elasticity of the opposing leg portions 14 and the bent tip 13, the lug terminal 10 can be temporarily secured on the printed circuit board 20 until it is fixed by soldering.
従って、半田浸漬法による半田付けが確実に達成できる
。Therefore, soldering by the solder dipping method can be reliably achieved.
本考案の重要な特徴は、プリント基板２０とラグ端子１
０とが半田２５により互に電気機械的に結合されるが、
この際、第８図に示すように、スルーホール２１内への
半田槽２８からの侵入半田が残されず且つラグ端子１０
の基部の透孔１１が半田浸漬処理で全く関係ない位置に
あることにより、半田埋まりが確実に阻止できる。The important features of the present invention are that the printed circuit board 20 and the lug terminals 1
0 are electromechanically coupled to each other by solder 25,
At this time, as shown in FIG.
By locating the through hole 11 at the base at a position completely unrelated to the solder dipping process, solder filling can be reliably prevented.
従って、第４図に示すリード支柱３２はスルーホール２

Then, a lead support 32 fixed to another board 30 is fixed to the base of the lug terminal 10 with solder 35.
従って異なる基板間の電気的機械的結合が遠戚できる。Therefore, electrical and mechanical coupling between different substrates can be distantly related.
特に、本考案に係る構造では各基板の修理、交換におい
ての分解時にその離脱も比較的容易であるという利点も
ある。In particular, the structure according to the present invention has the advantage that it is relatively easy to remove each board when it is disassembled for repair or replacement.
