サブプリント板２とを平行に装着しである。As described above, a terminal fitting consisting of a lower terminal fitting 10 and an upper terminal fitting 20 is mounted on the opposite edge side, and the opposite side edge side is connected by a hinge member 3 to connect the mother printed board 1 and the sub printed board 2. and are installed in parallel.
したがって、下部端子金具１０とサブプリント板２とを
固着している固着ねじ２８を取り外すと、サブプリント
板２は蝶番部材３を軸にして扉状に開閉し得る。Therefore, when the fixing screws 28 fixing the lower terminal fitting 10 and the sub-printed board 2 are removed, the sub-printed board 2 can be opened and closed like a door around the hinge member 3.
よって、サブプリント板２は勿論のこと、マザープリン
ト板Ｉに実装した搭載部品のチエツク。Therefore, check not only the sub printed board 2 but also the components mounted on the mother printed board I.
電気試験、保守等が容易である。Electrical testing, maintenance, etc. are easy.
下部端子金具１０と上部端子金具２ｏとの電気的接続に
ついて、第４図を参照しながら説明する。The electrical connection between the lower terminal fitting 10 and the upper terminal fitting 2o will be explained with reference to FIG. 4.
サブプリント板２を閉じる前に第４図（ａ）に示すよう

整すする。Before closing the sub-printed board 2, as shown in FIG. 1-
This is the position where the sub printed board 2 becomes parallel to the mother printed board 1 when it comes into contact with the upper end surface of the printed board 19. ).
そして、サブプリント板２を閉じて、第４図（ｂ）に示
すように、上部端子金具２０の貫通孔２３内に下部端子
金具１０の筒体１２を挿入する。Then, the sub-printed board 2 is closed, and the cylindrical body 12 of the lower terminal fitting 10 is inserted into the through hole 23 of the upper terminal fitting 20, as shown in FIG. 4(b).
この際、上部端子金具２０の下部側面に切欠き２４を設
けであるので、筒体１２の先端部が貫通孔２３の側壁に
衝突することがない。At this time, since the notch 24 is provided in the lower side surface of the upper terminal fitting 20, the tip of the cylindrical body 12 does not collide with the side wall of the through hole 23.
上部端子金具２０の下端面が調整ナツト１９の上端面に

ツト１９の上端面に圧着させる。After the lower end surface of the upper terminal fitting 20 comes into contact with the upper end surface of the adjustment nut 19, insert the tip of the fixing screw 28 into the sub-printed board 2.
hole and the through hole 23 of the upper terminal fitting 20, screw the threaded part into the screw hole 13 of the lower terminal fitting 10, tighten the fixing screw 28, and adjust the lower end surface of the upper terminal fitting 20 of the adjustment nut 19. Press it onto the top end surface.
よって、マザープリント板Ｉの電源パターン−下部端子
金具１０−調整ナット１９−上部端子金具２〇−サブプ
リント板２という、低インピーダンスの電源供給回路が
、マザープリント板ｌとサブプリント板２との間に構成
されろ。Therefore, a low impedance power supply circuit consisting of the power supply pattern of the mother printed board I, the lower terminal fitting 10, the adjustment nut 19, the upper terminal fitting 20, and the sub printed board 2 connects the mother printed board I and the sub printed board 2. be composed in between.
なお、固着ねじ１Ｂを用いて、下部端子金具１０をマザ
ープリント板１に取付け、マザープリント板１と下部端
子金具１０とを一体に固着しである。The lower terminal fittings 10 are attached to the mother printed board 1 using fixing screws 1B, and the mother printed board 1 and the lower terminal fittings 10 are fixed together.
よって、固着ねじ２８を締め付けても突子１５とスルー
ホールとを固着している半田に応力が付与されないので
、半田が剥離したり、亀裂が入る恐れがなく、下部端子
金具１０と電源パターンとが接続不良になる恐れがない
。Therefore, even when the fixing screw 28 is tightened, stress is not applied to the solder fixing the projection 15 and the through hole, so there is no risk of the solder peeling off or cracking, and the connection between the lower terminal fitting 10 and the power supply pattern is eliminated. There is no risk of poor connection.
また、下部端子金具と上部端子金具とよりなる端子金具
の搭載位置、数量は、第３図に示した位置等に限定され

載できるものでしる。Furthermore, the mounting position and quantity of the terminal fittings, which are composed of the lower terminal fitting and the upper terminal fitting, are not limited to the positions shown in Fig. 3, and the desired number and number of terminal fittings can be mounted at desired positions on the printed board. I'll write something down.
なお、アースパターン用の端子金具は、電源用の端子金
具とは別の位置に設置することは勿論のことである。It goes without saying that the terminal fitting for the ground pattern is installed at a different position from the terminal fitting for the power supply.
さらにまた、下部端子金具１０に筒体１２を設けること
なく、第１図に示したように下部端子金具１０の上端面
