It has mutually perpendicular wall surfaces 20a, 2ob and 20'a, 20'b that engage with the walls 18C, 18d, respectively, and has a triangular cross section.
電気部品12は、またケース14の上縁付近に取付孔1
8の周縁上面に係合するフランジ24を有する。The electrical component 12 also has a mounting hole 1 near the upper edge of the case 14.
It has a flange 24 that engages with the upper surface of the periphery of 8.
この電気部品12は、第3図A、Bに示すように、フラ
ンジ24を有する側と反対側の端部(底部)側から取付
板16の取付孔18に上方がら差込んで取付けられる。As shown in FIGS. 3A and 3B, this electrical component 12 is mounted by being inserted into the mounting hole 18 of the mounting plate 16 from above from the end (bottom) side opposite to the side having the flange 24.
このようにすると、2つの弾性ストッパ片20.20’
は取付孔18の壁面で押されて内側に撓み、肩部21.
21’が取付孔18を通過して解放されると、これらの
肩部21.21’が取付孔18の周縁下面に係合するよ
うに弾性ストッパ氷20.2(1のばね復元力によって
戻され、従って電気部品12は弾性ストッパ片20.2
0’の肩部21.21’とフランジ24とによって挾ま
れて固定される。In this way, the two elastic stopper pieces 20, 20'
is pushed by the wall surface of the mounting hole 18 and bends inward, and the shoulder portion 21.
21' passes through the mounting hole 18 and is released, the elastic stopper ice 20.2 (1) is returned by the spring restoring force so that these shoulders 21.21' engage the lower peripheral surface of the mounting hole 18. Therefore, the electrical component 12 is connected to the elastic stopper piece 20.2.
It is sandwiched and fixed by the shoulder portion 21, 21' of 0' and the flange 24.
第4図A、 Bは従来技術の弾性ストッパ片と本考案に
用いられる弾性ストッパ片との横断面を示す。4A and 4B show cross sections of the elastic stopper piece of the prior art and the elastic stopper piece used in the present invention.
従来の弾性ストッパ片の横断面積aX3a=3a2とし
、本考案に用いられる弾性ストッパ片の横断面積が従来
の場合と等しい横断面積(JτT)2/2)−3a2と
すると、従来技術では断面2次モーメントはπx3ax
a34で゛あるのに対し、本考案で第5図のX方向及び
y方向の断面2次モーメントはa4、U方向の断面2次
モーメントは2a4となる。If the cross-sectional area of the conventional elastic stopper piece is aX3a=3a2, and the cross-sectional area of the elastic stopper piece used in the present invention is equal to the conventional case (JτT)2/2)-3a2, then in the conventional technology, the cross-sectional area is quadratic. The moment is πx3ax
In contrast, in the present invention, the moment of inertia of area in the X direction and y direction in FIG. 5 is a4, and the moment of inertia of area in the U direction is 2a4.
従って、本考案の取付装置ではあらゆる方向の曲げに対
する強さが従来技術に比べて大きく、電気部品が堅固に
固定され、また水平方向の動きがなくなることが判る。Therefore, it can be seen that the mounting device of the present invention has greater strength against bending in all directions than the prior art, the electrical components are firmly fixed, and there is no horizontal movement.
本考案によれば、上記のように、電気部品を従来に比べ
て著しく堅固に取付けることができる実益がある。According to the present invention, as described above, there is a practical advantage that electrical components can be mounted more firmly than in the past.
