挿入したのち、前記抜止具１を電子部品１１を覆
つて押圧すればよい。 First, the lead pin 16 is inserted into the pin hole 10a of the printed circuit board 10, and the wiring is fixed to the socket 14 by soldering as appropriate. Then, after inserting the lead pin 12 of the electronic component 11 into the connection terminal hole 15 of the socket 14, the stopper 1 may be pressed so as to cover the electronic component 11.
すなわち、抜止具１は前記押圧動作により側壁
３，３が若干開いて、その係止爪部７がソケツト
１４のベース下面と係止するとともに、弾性片部
５の押圧部６が電子部品１１の上面を押圧するこ
とになる。 That is, the side walls 3, 3 of the removal stopper 1 are slightly opened by the pressing operation, and the locking claws 7 of the stopper 1 lock with the lower surface of the base of the socket 14, and the pressing portion 6 of the elastic piece 5 opens the electronic component 11. This will press the top surface.
したがつて、電子部品１１は、下端がソケツト
１４のベース下面に係止された抜止具１の弾性片

脱落することはない。さらに、リードピン１６が
丸棒体であれば、突部８はリードピン１６の外周
にガイドされるから、抜止具１の取付けは極めて
容易に行なえる。 Therefore, the electronic component 11 is prevented from slipping out of the socket 14 by the elastic piece 5 of the pull-out stopper 1 whose lower end is locked to the lower surface of the base of the socket 14, and the protrusion 8 of the pull-out stopper 1 Since it is located between the lead pins 16, it will not slide in the longitudinal direction and fall off. Furthermore, if the lead pin 16 is a round rod, the protrusion 8 is guided by the outer periphery of the lead pin 16, so that the retainer 1 can be attached very easily.
また、抜止具１は、側壁３，３を開くことによ

とができる。 The elastic piece 5 of this retainer 1 is formed by a portion of the top wall 2 and side walls 3, 3 by providing a notch 4 across the top of the top wall 2 and side walls 3, 3. It is easy to mold with a mold and can be molded to a certain extent in the longitudinal direction. Therefore, even a long electronic component can be fixed with one stopper.
なお、抜止具１は合成樹脂に限らず金属板で構
成してもよいが、この場合、少なくとも突部８は
合成樹脂とし、リードピン１６同志の短絡等を防
止する必要がある。 The retainer 1 is not limited to synthetic resin and may be made of a metal plate, but in this case, at least the protrusion 8 must be made of synthetic resin to prevent short circuits between the lead pins 16.
前記実施例では、弾性片部５を抜止具１の中央

て形成してもよい。 In the above embodiment, two elastic pieces 5 are provided in the center of the retainer 1 so as to face each other from both sides, but it is also possible to provide one elastic piece 5 in the center as shown in FIG. 5, or as shown in FIG. Alternatively, two sets may be provided on both sides. In the above embodiment, the elastic piece 5 is provided extending from the side wall 3 to the top wall 2, but it may be formed by deforming the top wall 2.
さらに、弾性片部５の押圧部６は必ずしも湾曲

品に適用でき汎用性を有する。(Effects of the Invention) As is clear from the above explanation, according to the removal stopper of the present invention, the printed circuit board is inexpensive because there is no hole for attaching the removal stopper to the printed circuit board. Furthermore, since the retainer is attached from above the electronic component, it is easy to attach and detach, and since the upper surface of the electronic component is pressed by the elastic piece, it can be applied to electronic components within a predetermined height range, and has versatility.
また、本考案の抜止具は、門形形状であり、上
面壁と側壁の一部で弾性片部を形成しているので
成形が容易であり、長手方向にある程度長く成形

作業が簡単である。 In addition, the pull-out stopper of the present invention has a portal shape, and the upper wall and part of the side wall form an elastic piece, so it is easy to mold, and it can be molded to a certain length in the longitudinal direction. Only one piece needs to be used for fixing electronic components, making it easy to mount electronic components onto printed circuit boards.
さらに、突部の存在により、抜止具は電子部品
