２図の取付部を設けた場合には第４図に示す如くになり
、共にそのパターン不可範囲は大きく現在の高密度実装
を必要とする機器には不利となる。These methods have high manufacturing costs, and when the striped bushing shown in FIG. 1 is used, the unpatterned area becomes as shown in FIG. 3 (the unpatterned area 7 is the hatched area), and When a mounting portion is provided, the result will be as shown in FIG. 4, and the range in which the pattern cannot be used is large, which is disadvantageous for current equipment requiring high-density mounting.
本考案はこの欠点を改良するために案出されたものであ
る。The present invention was devised to improve this drawback.
このため本考案においては、電子機器等の金属シャーシ
にプリント板を保持せしめるプリント板保持構造におい
て、該金属シャーシの複数個所に僅かな間隔を隔てた２
本の爪並びに該２本の爪に対して、間隔を隔て設けられ
、該２本の爪より短かいプリン１〜板支承部分よりなる
プリント板固定部を設けると共に、該固定部に対応して
プリント板に切欠きを設け、該シャーシにプリント板を
載置した後、前記２本の爪を新曲してプリント板を固定
したことを特徴とするものである。For this reason, in the present invention, in a printed board holding structure for holding a printed board on a metal chassis of an electronic device, etc., there are two
A printed board fixing part is provided for the book claw and the two claws at a distance from each other and is shorter than the two claws. The present invention is characterized in that a notch is provided in the printed board, and after the printed board is placed on the chassis, the two claws are bent to fix the printed board.
以下、添付図面に基づいて本考案の実施例につき詳細に
説明する。Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
第５図は本考案のプリント板保持構造を斜視図により示
す。FIG. 5 shows a perspective view of the printed board holding structure of the present invention.
図において１は金属製のシャーシである。In the figure, 1 is a metal chassis.
このシャーシ１の複数個所には夫々僅かな間隔を隔てた
２本の爪８，８′より成るプリント板固定部９が形成さ
れている。Printed board fixing portions 9 are formed at a plurality of locations on the chassis 1, each consisting of two claws 8, 8' spaced apart from each other by a small distance.
この爪８，８′の長さはプノント板３の上面より若干突
き出る程度となし、爪の左右には逃げ部１０を設けて爪
の変形を容易にしている。The lengths of the claws 8, 8' are such that they slightly protrude from the upper surface of the Pnont plate 3, and relief portions 10 are provided on the left and right sides of the claws to facilitate deformation of the claws.
また爪８と爪８′との間隔はねし廻しの先端が挿入でき
る程度としておく。Further, the spacing between the claws 8 and 8' should be such that the tip of the screwdriver can be inserted therein.
このシャーシ１の固定部９に対応してプリント板３には
爪８，８′が挿入される切欠き１１が設けられている。Corresponding to the fixed portion 9 of the chassis 1, the printed board 3 is provided with a notch 11 into which the claws 8, 8' are inserted.
このように形成されたシャーシ１にプリント板３を載せ
て爪８と爪８′との間にねし廻し１２の先端を挿入して
爪の間隔を拡げるようにねし廻し１２を矢印の如く左右
に回動すれば爪８，８′は第６図に鎖線で示す如く変形
してプリント板３を固定することになる。Place the printed circuit board 3 on the chassis 1 formed in this way, insert the tip of the screwdriver 12 between the claws 8 and 8', and move the screwdriver 12 in the direction of the arrow so as to widen the gap between the claws. When rotated left and right, the claws 8, 8' are deformed as shown by chain lines in FIG. 6 to fix the printed board 3.
なお第５図に示した如く爪８，８′の左右に若干のプリ
ント板支承部分１３を残してシャーシ１とプリント板３
との間にすき間１４を設ければ第７図に示す如くプリン
ト板裏面のパターン不可範囲７は従来に比し小範囲とす
ることができる。As shown in FIG. 5, the chassis 1 and the printed board 3 are attached to each other, leaving some printed board supporting parts 13 on the left and right sides of the claws 8 and 8'.
If a gap 14 is provided between them, the area 7 where the pattern cannot be formed on the back side of the printed board can be made smaller than in the past, as shown in FIG.
また第６図に示すように爪８，８′は逃げ１０を設けて
長くしであるためカシメが容易となり、爪８゜８′とプ
リント板の切欠きとの間に多生のすき間Ｃかあっても確
実にプリント板３を固定することができる。In addition, as shown in Fig. 6, the claws 8, 8' are long with a relief 10, which makes caulking easier, and there is a large gap C between the claws 8, 8' and the notch in the printed board. Even if there is a problem, the printed board 3 can be securely fixed.
このため製造公差を緩くすることができ製造コストが安
価となる。Therefore, manufacturing tolerances can be relaxed and manufacturing costs can be reduced.
またプリント板３をシャーシ１より取外す際はベンチ等
で２本の爪の先端を挾めば容易に取外すことが可能であ
り、爪の曲げ量が少ないため数回のカシメ取外しに充分
耐えることができる。In addition, when removing the printed circuit board 3 from the chassis 1, it can be easily removed by holding the tips of the two claws on a bench or the like, and since the amount of bending of the claws is small, it can withstand being crimped and removed several times. can.
さらに本考案のプリント板保持構造はプリント板を保持
することができるばかりでなく第８図および第９図に示
す如く爪８又は８′にワイヤ１５を巻いて半田付けを行
うか、或はアースパターン１６を爪８，８′に半田付け
してアースをとる場合にも有効である。Furthermore, the printed board holding structure of the present invention is not only capable of holding a printed board, but can also be connected to the ground by winding a wire 15 around the claw 8 or 8' and soldering it, as shown in FIGS. 8 and 9. This is also effective when grounding is established by soldering the pattern 16 to the claws 8, 8'.
