ら構成されている。This embodiment has a plurality of notches 22 and a lever insertion hole 24 for inserting and extracting a plurality of printed circuit boards 46 into and out of a connector (not shown), and has a lever insertion hole 24 in a direction perpendicular to the surface of the printed circuit board 46. A freely movable L-shaped plate-shaped lock bar 21,
It has a tapered locking part 26 on the upper surface of one end, a trapezoidal projection 28 on the upper center surface, and a projection 29 on the side surface of the other end.
and a plate-shaped lock part 31 having a slit 33 that divides the upper part and the lower part, and a dogleg-shaped operating part 31 formed at the other end of the lock part and provided with a convex knob 32 at the end.
and a lever 25 which is inserted into the lever insertion hole 24.
第２図および第３図において、プリント基板挿入時には
、レバー２１に設けられたレバー挿入穴２４はレバー２
５の突起部２８と係合しており、装置本体側に設けられ
た角穴３６は該レバー２５の平坦部３４と係合している
。2 and 3, when inserting the printed circuit board, the lever insertion hole 24 provided in the lever 21 is inserted into the lever 21.
The square hole 36 provided on the device body side engages with the flat part 34 of the lever 25.
このとき、つまみ３２を引張っても係止部２６の一方の
垂直面２７が該角穴３６の上部に当たり、該レバー２５
は引き抜けないように構成されている。At this time, even if the knob 32 is pulled, one vertical surface 27 of the locking part 26 hits the upper part of the square hole 36, and the lever 25
is constructed so that it cannot be pulled out.
つまみ３２を押すと、装置本体の角穴３６は平坦部３４

る。When the knob 32 is pressed, the square hole 36 of the main body of the device is moved to the flat part 34.
Due to the deformation of the slit 33, the square hole 24 moves beyond the protrusion 28 to the flat part 35, and at the same time, the square hole 24 moves from the protrusion 30 of the lever 25 to the protrusion 32, that is, the operating portion 31.
操作部３１はくの字形状を有しているためこのレバー２
５の移動により該バー２１は穴２４を介して左方Ｃヘス
ライドする。Since the operation part 31 has a dogleg shape, this lever 2
5, the bar 21 slides to the left C through the hole 24.
第４図を参照してさらに詳細に説明する。This will be explained in more detail with reference to FIG.

の抜けは防止される。When unlocked, the printed circuit board 46 is
It is located at a position corresponding to the notch 22 of 1 and can be inserted and removed,
When the knob 32 of the lever 25 is pressed, the bar 21 moves to the left C, and the portion 23 without a notch engages with the end surface 48 of the notch portion 47 of the printed circuit board 46, preventing the printed circuit board from coming off in the forward direction. be done.
尚ベース４１の角穴３６がレバー２５の平坦部３５の位
置にあるときは突起部２９の垂直面３０が該角穴３６の
右部に当たり、それ以上は押し込まれず、また、突起２
８は該角穴３６よりも外形が少し大きいので振動等で作
用する力によっては平坦部３４と３５との間を角穴３６
が往復することはない。When the square hole 36 of the base 41 is in the position of the flat part 35 of the lever 25, the vertical surface 30 of the protrusion 29 hits the right side of the square hole 36, and is not pushed in any further.
8 has a slightly larger outer diameter than the square hole 36, so depending on the force acting on it due to vibration etc., the square hole 36 may be inserted between the flat parts 34 and 35.
There is no reciprocation.
また、本実施例のバー２１はＬ字板状であるが単に平板
状のものでもよい。Further, although the bar 21 in this embodiment has an L-shaped plate shape, it may be simply a flat plate.
以上、本考案には、部品点数の減少および組立工数の減
少を達成できるという効果がある。As described above, the present invention has the effect of reducing the number of parts and assembly man-hours.
