Description
本発明は、筐体又はシャーシに上側に向けてリブを突設し、基板に前記リブを挿入する孔部を形成して、前記リブの上側を前記孔部に挿入することにより、前記基板を前記筐体又はシャーシに取り付けるようにした基板の取付構造に関するものである。 According to the present invention, a rib is protruded upward from a housing or a chassis, a hole for inserting the rib is formed in the substrate, and the upper side of the rib is inserted into the hole, thereby The present invention relates to a substrate mounting structure that is mounted on the casing or chassis.
従来、筐体又はシャーシに基板を取付固定するには、基板の四隅にビスを挿入し、このビスを筐体又はシャーシにねじ込むことによって、基板を筐体又はシャーシに取付固定していた。このように、ビスを使用していたので部品点数が多くなり、コスト高になるとともに、取付作業に手間がかかるという問題があった。 Conventionally, in order to attach and fix a substrate to a housing or a chassis, screws are inserted into the four corners of the substrate and screwed into the housing or the chassis to fix the substrate to the housing or the chassis. As described above, since the screws are used, the number of parts is increased, the cost is increased, and the mounting work is troublesome.
第1の従来技術を図4、図5に示す。この従来のプリント基板の取付け構造は、図4、図5に示すように、第二の支持体103の先端部に備えたT形突片106と、そのT形突片106の両側の矩形突片107、108とをプリント基板104の合成孔部110に嵌入し、第二の支持体103のT形突片106を第二の支持体106が立設する方向を軸として、T形突片106の水平片がプリント基板104の面上に位置するまで垂直片をひねることで係合して取付けるようにしている。(例えば、特許文献1参照)。 The first prior art is shown in FIGS. As shown in FIGS. 4 and 5, the conventional printed circuit board mounting structure includes a T-shaped protrusion 106 provided at the tip of the second support 103 and rectangular protrusions on both sides of the T-shaped protrusion 106. The pieces 107 and 108 are inserted into the synthetic hole portion 110 of the printed circuit board 104, and the T-shaped projecting piece is formed with the T-shaped projecting piece 106 of the second supporting body 103 as the axis in which the second supporting body 106 is erected The vertical pieces 106 are engaged and attached by twisting the vertical pieces until the horizontal pieces 106 are located on the surface of the printed circuit board 104. (For example, refer to Patent Document 1).
ところが、これにおいては、第2の支持片106の垂直片をひねるのに手間がかかり、また、ひねることによって強度が弱くなるという問題があった。しかも、プリント基板104を取り替えるときに、何回もひねることによって垂直片がちぎれる虞があるという問題があった。 However, in this, there is a problem that it takes time to twist the vertical piece of the second support piece 106, and the strength is weakened by twisting. Moreover, when the printed circuit board 104 is replaced, there is a problem that the vertical piece may be broken by twisting it many times.
第2の従来技術を図6に示す。この従来のプリント基板の取付構造は、図6に示すように、きょう体206に形成された支持部207をプリント基板209上の取付穴210に挿通し、しかる後プリント基板209をきょう体206の底面に対して平行に移動させることにより、プリント基板209をきょう体206にねじを使用せずに固定させるようにしている。(例えば、特許文献2参照)。 A second prior art is shown in FIG. As shown in FIG. 6, this conventional printed circuit board mounting structure inserts a support portion 207 formed in the housing 206 into a mounting hole 210 on the printed circuit board 209, and then attaches the printed circuit board 209 to the housing 206. By moving in parallel with the bottom surface, the printed circuit board 209 is fixed to the casing 206 without using screws. (For example, refer to Patent Document 2).
ところが、これにおいては、プリント基板209を移動させると、支持体207に対して取付穴210が移動して、プリント基板209がずれて外れてしまう恐れがあるという問題があった。 However, in this case, when the printed circuit board 209 is moved, the mounting hole 210 is moved with respect to the support 207, and there is a problem that the printed circuit board 209 may be displaced and removed.
第3の従来技術を図7、図8、図9に示す。この従来のプリント基板の取付構造は、図7、図8、図9に示すように、シャーシ311から起立された折曲片313は、その全体がプリント基板312の長穴312aに挿通できる幅寸法を有し、また折曲片313は折曲げ加工しやすい充分な高さ寸法を有している。長穴312a内に折曲片313が挿通されて、プリント基板312はシャーシ311上に隙間なく設置される。長穴312aから突出した折曲片313に設けられた爪313aをプリント基板312の表面にて曲げることにより、プリント基板312はシャーシ311の表面と爪313aの先端にて挟持されて固定されるようにしている。(例えば、特許文献3参照)。 The third prior art is shown in FIG. 7, FIG. 8, and FIG. As shown in FIGS. 7, 8, and 9, the conventional printed board mounting structure has a width dimension that allows the bent piece 313 erected from the chassis 311 to be inserted into the elongated hole 312 a of the printed board 312. Further, the bent piece 313 has a sufficient height dimension that facilitates bending. The bent piece 313 is inserted into the elongated hole 312a, and the printed circuit board 312 is installed on the chassis 311 without any gap. By bending the claw 313a provided on the bent piece 313 protruding from the long hole 312a at the surface of the printed circuit board 312, the printed circuit board 312 is sandwiched and fixed between the surface of the chassis 311 and the tip of the claw 313a. I have to. (For example, refer to Patent Document 3).
ところが、これにおいては、爪313aが折り曲げられているから、プリント基板312を取り外し難いという問題があった。
