Description

この発明は板状部材の締着構造に関する。   The present invention relates to a fastening structure for plate-like members.

従来の板状部材の締着構造の例を図７を参照して説明する。板状部材９にはねじ孔９ａが設けられ、板状部材８にはねじ挿通孔８ａが設けられている。挿通孔８ａを挿通したねじ３をねじ孔９ａにねじ込むことにより板状部材８および板状部材９が締着される。   An example of a conventional plate-like member fastening structure will be described with reference to FIG. The plate-like member 9 is provided with a screw hole 9a, and the plate-like member 8 is provided with a screw insertion hole 8a. The plate-like member 8 and the plate-like member 9 are fastened by screwing the screw 3 inserted through the insertion hole 8a into the screw hole 9a.

上記した従来の板状部材の締着構造では、ねじ３の締付けトルクによって、板状部材９は板状部材８の方に引っ張られて固定される。そして、板状部材９に直接取り付けられた部品に位置ずれを発生させる。この位置ずれにより板状部材９に取り付けられたパワーＩＣ等基板上の部品に応力が加わり、これらの部品が破損することがあった。   In the conventional plate-like member fastening structure described above, the plate-like member 9 is pulled and fixed toward the plate-like member 8 by the tightening torque of the screw 3. Then, a positional shift is caused in the component directly attached to the plate-like member 9. Due to this displacement, stress is applied to the components on the substrate such as the power IC attached to the plate-like member 9, and these components may be damaged.

特開昭６１−２４２３７９号公報に提案されたフロッピーディスク装置では、第２図に示すように板金シャーシ２９とシャーシ２８は板金シャーシ２９側に設けられた凸字状に屈曲した部位において長ねじ３０を介して結合されている。   In the floppy disk device proposed in Japanese Patent Laid-Open No. 61-242379, as shown in FIG. 2, the sheet metal chassis 29 and the chassis 28 are provided with long screws 30 at the bent portions provided on the sheet metal chassis 29 side. Are connected through.

上記特開昭６１−２４２３７９号公報に提案された板状部材の締着構造では、ねじの締付けトルクによる板状部材の応力は緩和されるが、板金シャーシ２９とシャーシ２８は長ねじ３０の周囲で離れているため、これらの板状部材はねじ締付けトルクにより変形し、締めすぎや、締付け不足が発生しやすくねじの締付けトルクの管理が困難である。
特開昭６１−２４２３７９号公報、明細書第２頁左下欄第２０行〜右下欄第３行、第２図 In the plate-like member fastening structure proposed in the above-mentioned Japanese Patent Laid-Open No. 61-242379, the stress of the plate-like member due to the tightening torque of the screw is relieved, but the sheet metal chassis 29 and the chassis 28 are arranged around the long screw 30. Therefore, these plate-like members are deformed by the screw tightening torque, so that over tightening or insufficient tightening is likely to occur, and it is difficult to manage the screw tightening torque.
