SUBSTRATE FITTING PART STRUCTURE FOR ELECTRICAL EQUIPMENT

PROBLEM TO BE SOLVED: To provide a substrate fitting part structure improved in assembling ability and positioning accuracy of a wiring board 17 on a housing 5.SOLUTION: On the two side walls of a substrate introduction part 26 of a housing 5, there are formed: positioning guide ribs 31 and 32 which are engaged by the two side groove-shaped notches 21 and 22 of a wiring substrate 17 for guiding and positioning the wiring substrate 17 on substrate mounting face 25. On the bottom wall of the substrate introduction part 26, there are formed attitude controlling guide ribs 33 and 34, in which the groove-shaped notches 33 and 34 in the bottom side of the wiring substrate 17 engage with the bottom wall of the substrate introduction part 26 for blocking the wiring substrate 17 from transversely turning when the wiring substrate 17 is guided by the positioning guide ribs 31 and 32. 【課題】配線基板１７のハウジング５への組付性と位置決め精度の向上を図る。【解決手段】ハウジング５の基板導入部２６の両側壁に、配線基板１７の両側辺の溝形切欠き２１，２２が係合し配線基板１７を案内して基板取付面２５に位置決めする位置決め用ガイドリブ３１，３２が形成され、基板導入部２６の底壁に、配線基板１７の底辺の溝形切欠き３３，３４が係合し配線基板１７が位置決め用ガイドリブ３１，３２による案内時に横向きに回転することを阻止する姿勢制御用ガイドリブ３３，３４が形成されている。【選択図】図１０
