【考案の詳細な説明】
本考案は、プリント基板取付装置に係り、特に比較的大
なるプリント基板を取付けるに適したプリント基板取付
装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed circuit board mounting device, and particularly to a printed circuit board mounting device suitable for mounting a relatively large printed circuit board.
比較的大なるプリント基板をシャーシに取付ける場合、
単にプリント基板とシャーシとをネジとめしたのでは、
プリント基板のプリント面がシャーシに接触して短絡等
の事故を生じるので好ましくない。When installing a relatively large printed circuit board to the chassis,
If you simply screwed the printed circuit board and chassis together,
This is undesirable because the printed surface of the printed circuit board may come into contact with the chassis, causing accidents such as short circuits.
前記短絡事故を防止する為には、ネジとめ部分にスペー
サを設ければよいが、故障時等の補修をする場合、プリ
ント基板全体をとりはずさなければならない。In order to prevent the short-circuit accident, a spacer may be provided at the screwed part, but when repairing a failure, the entire printed circuit board must be removed.
又、スペーサの必要が無く、かつ補修時にプリント基板
をとりはずす必要の無いプリント基板取付装置としては
、シャーシの前記プリント基板のプリント面に対向する
部分に孔を穿設する方法がある。Further, as a printed circuit board mounting device that does not require a spacer and does not require removing the printed circuit board during repair, there is a method in which a hole is bored in a portion of the chassis that faces the printed surface of the printed circuit board.
即ち前記孔の穿故により、プリント基板のプリント面と
シャーシとの接触が無くなるから、スペーサは不要であ
り、かつ補修時には、シャーシの裏側から補修作業を行
い得るので、前記方法は実用的なものである。That is, since the printed surface of the printed circuit board and the chassis are no longer in contact with each other due to the hole being punched, there is no need for a spacer, and the repair work can be performed from the back side of the chassis during repair, so the method described above is practical. It is.
しかしながら、前記方法を大なるプリント基板に利用す
る場合は、シャーシに穿設される孔も大となり、その為
、シャーシの強度低下及び外力によるプリント基板の破
損を招き好ましくない。However, when the above method is applied to a large printed circuit board, the holes drilled in the chassis also become large, which is undesirable as it reduces the strength of the chassis and causes damage to the printed circuit board due to external force.
本考案は上述の点に鑑み威されたもので、以下実施例に
基き、図面を参照しながら説明する。The present invention has been developed in view of the above points, and will be described below based on embodiments and with reference to the drawings.
第１図は本考案に利用されるシャーシの一例を示すもの
で、１はシャーシ、２は該シャーシ１に穿設された孔、
３は該孔２を横切って前記シャーシ１の縁部１ａ及び１
ｂを一体に連結する補強腕である。FIG. 1 shows an example of a chassis used in the present invention, where 1 is a chassis, 2 is a hole drilled in the chassis 1,
3 crosses the hole 2 to the edges 1a and 1 of the chassis 1.
This is a reinforcing arm that connects b together.
しかして、前記補強腕３はプレス加工によって形成され
る。Thus, the reinforcing arm 3 is formed by press working.
すなわち、前記孔２を穿設する場合、第１図に二点鎖線
で示す如く、補強腕３の側縁部３ａを残す様な穿設が行
なわれる。That is, when the hole 2 is bored, the hole 2 is bored so as to leave the side edge 3a of the reinforcing arm 3 as shown by the two-dot chain line in FIG.
そして、プレス加工により、前記側縁部３ａが折り曲げ
られ第２図に示す如く断面コ字状となるとともに、全体
的に押圧されるから前記補強腕３の両端部３ｂ及び３Ｃ
が伸びて前記補強腕３の縦断面は、Ｖ状となる。Then, by pressing, the side edge portion 3a is bent to have a U-shaped cross section as shown in FIG.
is extended, and the longitudinal section of the reinforcing arm 3 becomes V-shaped.
第３図は、第１図のシャーシにプリント基板を取付けた
状態を示す断面図で、１はシャーシ、３は該シャーシ１

リント基板４の裏面との間に配設されたスペーサ、８及
び９はプリント基板４とシャーシ１とを螺合する取付ネ
ジ、及び１０はプリント基板４の上面から前記スペーサ
７の中心孔７ａに螺合される取付ネジである。FIG. 3 is a cross-sectional view showing the printed circuit board attached to the chassis of FIG. 1, where 1 is the chassis and 3 is the chassis 1.
a reinforcing arm, 4 a printed circuit board with components 5 and 6 on the front side and a printed surface on the back side; 7 a spacer disposed between the upper surface of the reinforcing arm 3 and the back surface of the printed circuit board 4; and 9 are mounting screws for screwing together the printed circuit board 4 and the chassis 1, and 10 are mounting screws that are screwed into the center hole 7a of the spacer 7 from the top surface of the printed circuit board 4.
本考案によれば、断面Ｖ形の補強腕３が設けられている
為、シャーシ１に大きな孔２を穿設しても強度低下を防
止出来るという効果を得られる。According to the present invention, since the reinforcing arm 3 having a V-shaped cross section is provided, it is possible to prevent a decrease in strength even if a large hole 2 is bored in the chassis 1.
特に断面が“Ｕ・形にプレスされているので、その補強
能力は大きく、シかも補強腕３自体がプリント基板４の
プリント面に接触しないがら、短絡防止の効果も有する
。In particular, since the cross section is pressed into a "U" shape, its reinforcing ability is large, and although the reinforcing arm 3 itself does not come into contact with the printed surface of the printed circuit board 4, it also has the effect of preventing short circuits.
更に本考案に依れば、プリント基板４の裏面と補強腕３
との間には、スペーサ７が配置されているから、プリン
ト基板４自体の破損を防止出来る。Furthermore, according to the present invention, the back surface of the printed circuit board 4 and the reinforcing arm 3
Since the spacer 7 is arranged between the printed circuit board 4 and the printed circuit board 4, damage to the printed circuit board 4 itself can be prevented.
前記スペーサ７は、第４図に示す如く、中心孔７ａと２
本の脚７ｂとを有しており、前記中心孔７ａにネジを螺
合することにより前記脚７ｂの間隔が広がるように構成
されている。The spacer 7 has center holes 7a and 2, as shown in FIG.
It has book legs 7b, and is configured such that the distance between the legs 7b is widened by screwing a screw into the center hole 7a.
従って、前記脚７ｂをシャーシの孔１１に挿入した上で
ネジを螺合すれば、シャーシとスペーサとの取付、及び
プリント基板とスペーサとの取付は簡単に行なえる。Therefore, by inserting the legs 7b into the holes 11 of the chassis and screwing together the screws, the chassis and the spacer can be easily attached, and the printed circuit board and the spacer can be attached easily.
以上述べた如く、本考案に係るプリント基板取付装置は
、プリント基板上に配設された部品の補修を簡単に行な
うことが出来るとともに、シャーシ及びプリント基板の
破損防止を行うことが出来る実用的なものである。As described above, the printed circuit board mounting device according to the present invention is a practical device that can easily repair parts arranged on a printed circuit board and prevent damage to the chassis and printed circuit board. It is something.
