<P>PROBLEM TO BE SOLVED: To easily fix a substrate with a sensor for detecting intrusion of a suspicious person to a mounting plate fixed to a wall surface. <P>SOLUTION: When mounting a substrate 8 to a mounting plate 7 fixed to a wall surface 2, the substrate 8 is inclined forward, a lower side plate 27 of a housing part 30 is brought into contact with a lower end of the mounting plate 7, the substrate 8 is rotationally moved to a rear side with the contact part as a center, and the housing part 30 of the substrate 8 is superposed on an outer side of the mounting plate 7. After that, the substrate 8 is moved downward until an upper side plate 24 contacts an upper surface part 13 of the mounting plate 7, then a fitting protrusion 31 is fitted into an engaging hole 18 and an engaging protrusion 33 is engaged with an engaging pawl piece 23. Therefore the substrate 8 is temporarily fixed to the mounting plate 2 and a fixing screw 9 is screwed to a screw hole 22 through a through hole 32, thereby properly fixing the substrate 8 to the mounting plate 7. <P>COPYRIGHT: (C)2013,JPO&INPIT |
