た。As described in Japanese Patent Application Laid-Open No. 60-128699, a conventional board fixing structure is such that long plate-shaped reinforcing metal fittings are attached to the sides of a pair of connectors mounted on a board, so that the connectors can be easily inserted and removed. This was to prevent warping and distortion of the board.
また、特開昭６２−２４２３９８号公報に記載のように

延設することにより、基板面の垂直方向に力を加えても
基板のそりや歪みを防ぐものであった。Furthermore, as described in Japanese Patent Application Laid-Open No. 62-242398, by extending the heat sink on the board in the longitudinal direction of the board to both ends of the board, even if force is applied in the direction perpendicular to the board surface, the board will not work. This was to prevent warping and distortion.

が必要であった。2(a) and 2(b) show a conventional board fixing structure, in which the bracket 1 only has the function of fixing the printed circuit board 2 and the main chassis 5, and the board support part 7 prevents the board from deflecting when the connector 4 is inserted or removed. However, it required a separate support component and a wiring-prohibited area around the board support part.

て固定する部分のみであった。FIG. 2(c) shows the shape of a conventional bracket, in which the only parts that support the printed circuit board are parts to which the printed circuit boards at both ends are fixed with fixing screws.
上記従来技術は、基板をメインシャーシに固定するブラ
ケットとは別に、コネクタ挿抜時の基板のたわみによる
配線パターン切断、半田付部接触不良を防ぐための基板
支持部品が必要であった。In addition to the bracket for fixing the board to the main chassis, the above-mentioned conventional technology requires a board support component to prevent wiring pattern breakage and poor contact at soldered parts due to board deflection during connector insertion and removal.
また、基板支持部品が導電性材質の場合は、基板が基板
支持部品と接触する部分を配線禁止領域とする必要があ
った。Further, when the board support component is made of a conductive material, it is necessary to set a portion where the board comes into contact with the board support component as a wiring prohibited area.
本発明の目的は、簡単な構造で基板面と垂直方向のコネ
クタ挿抜時の基板のたわみによるパターン切断、半田付
部接触不良を防ぐことにある。An object of the present invention is to use a simple structure to prevent pattern breakage and poor contact at soldered parts due to board deflection when inserting and removing a connector in a direction perpendicular to the board surface.
上記目的を達成するために、本発明の基板固定構造は、
コネクタをブラケット近傍にブラケットと平行に直線状
に集中配線し、ブラケットの板厚面で基板のコネクタ実
装面の裏側を支持することを特徴とする。In order to achieve the above object, the substrate fixing structure of the present invention includes:
The connector is concentrated in a straight line near the bracket in parallel with the bracket, and the thickness of the bracket supports the back side of the connector mounting surface of the board.
本構造により、コネクタ挿抜時にプリント基板に力がか
かつても、ブラケットの板厚でコネクタ実装面の裏側か
ら基板を直線状に支持しているため、いずれのコネクタ
挿抜を行っても基板のたわみを発生することがない。With this structure, even if force is applied to the printed circuit board when inserting or removing the connector, the thickness of the bracket supports the board in a straight line from the back side of the connector mounting surface, so no matter how the connector is inserted or removed, the board will not bend. Never occurs.

ねじ座５ａにねし止め固定されている。An embodiment of the present invention will be described below with reference to FIG. 1st
In FIGS. (a) and (b), reference numeral 1 denotes a bracket for fixing the printed circuit board 2 to the in-chassis 5. Printed circuit board 2
is fixed to the bracket 1 with screws 3, and the bracket 1 is fixed to a screw seat 5a provided on the main chassis 5 with screws 6.
また、プリント基板２は基板面に対し垂直方向に挿抜す

、導電性材質のブラケット１とプリント基板２との接触
による配線禁止領域を特に設けることもない。With this structure, even if stress is applied to the printed circuit board 2 when inserting or removing the connector 4, the printed circuit board 2 is linearly supported from the back side of the connector mounting surface by the thickness of the bracket 1, so there is no bending of the board. . In addition, since the connectors 4 are concentrated near the bracket 1 and parallel to the bracket 1, it is only necessary to support the end of the printed circuit board 2, and wiring due to contact between the bracket 1 and the printed circuit board 2, which are made of conductive material, is prohibited. There is no need to set up a particular area.
