Description

この発明はシャーシへの金具の取付構造に関する。   The present invention relates to a mounting structure for a metal fitting to a chassis.

従来のシャーシへの金具の取付構造の例を図2により説明する。図2に示すシャーシ3には底板から右側板3aと左側板3bが垂直に立上がり、右側板3a、左側板3bおよび底板折曲げることにより垂直面の後板3cが底板から立上がるように形成されている。   An example of a conventional mounting structure of a metal fitting to a chassis will be described with reference to FIG. The chassis 3 shown in FIG. 2 is formed so that the right side plate 3a and the left side plate 3b rise vertically from the bottom plate, and the right side plate 3a, left side plate 3b and bottom plate are bent so that the rear plate 3c of the vertical surface rises from the bottom plate. ing.

金具4は断面コ字形に形成されており、コ字形後面4aの両側から直角方向にコ字形右側面4bとコ字形左側面4cが延びている。シャーシ3の後板3cに設けられねじ挿通穴3d、3fに夫々ねじ7、7が挿通され、金具4のコ字形後面4aのねじ穴(図2に見えていない)にねじ込まれることにより金具4がシャーシ3に締着される。   The metal fitting 4 is formed in a U-shaped cross section, and a U-shaped right side surface 4b and a U-shaped left side surface 4c extend in a right angle direction from both sides of the U-shaped rear surface 4a. Screws 7 and 7 are respectively inserted into screw insertion holes 3d and 3f provided in the rear plate 3c of the chassis 3, and the metal fitting 4 is screwed into a screw hole (not visible in FIG. 2) of the U-shaped rear surface 4a of the metal fitting 4. Is fastened to the chassis 3.

このシャーシへの金具の取付構造では、ねじ挿通穴3d、3fの内径とねじ7の外形との差だけ金具4のシャーシ3に対する位置ずれが生じ、金具4がシャーシ3に正確に位置決めされないという問題があった。   In this mounting structure of the metal fitting to the chassis, there is a problem that the metal fitting 4 is displaced with respect to the chassis 3 by the difference between the inner diameters of the screw insertion holes 3d and 3f and the outer shape of the screw 7, and the metal fitting 4 is not accurately positioned on the chassis 3. was there.

図3に示す従来のシャーシへの金具の取付構造の他の例では、シャーシ5は底板から右側板5aと左側板5bが垂直に立上がり、右側板5a、左側板5bおよび底板折曲げることにより垂直面の後板5cが底板から立上がるように形成されている。   In another example of the mounting structure of the metal fitting to the conventional chassis shown in FIG. 3, the chassis 5 rises vertically from the bottom plate so that the right side plate 5a and the left side plate 5b rise vertically, and is bent vertically by bending the right side plate 5a, the left side plate 5b and the bottom plate. The rear plate 5c of the surface is formed so as to rise from the bottom plate.

金具6は断面コ字形に形成されており、コ字形後面6aの両側から直角方向にコ字形右側面6bとコ字形左側面6cが延びている。シャーシ5の右側板5aおよび左側板5bに夫々設けられねじ挿通穴5d、5eに夫々ねじ7、7が挿通され、金具6のコ字形右側面6bおよびコ字形左側面6cに夫々設けられたねじ穴6dおよび6eにねじ込まれることにより金具6がシャーシ5に締着される。   The bracket 6 is formed in a U-shaped cross section, and a U-shaped right side surface 6b and a U-shaped left side surface 6c extend in a right-angle direction from both sides of the U-shaped rear surface 6a. Screws 7 and 7 are respectively inserted into the screw insertion holes 5d and 5e provided on the right side plate 5a and the left side plate 5b of the chassis 5, and screws provided on the U-shaped right side surface 6b and the U-shaped left side surface 6c of the metal fitting 6, respectively. The metal fitting 6 is fastened to the chassis 5 by being screwed into the holes 6d and 6e.

なお、ねじ7、7を締め付けて金具6を固定するとき、シャーシ5の底板に載せた直方体の治具の側面に金具6のコ字形後面6aを密接させてコ字形後面6aが垂直となるように位置決めされる。   When fastening the screws 7 and 7 to fix the metal fitting 6, the U-shaped rear surface 6a of the metal fitting 6 is brought into close contact with the side surface of the rectangular parallelepiped jig placed on the bottom plate of the chassis 5 so that the U-shaped rear surface 6a becomes vertical. Is positioned.

このシャーシへの金具の取付構造では、金具6が図4(a)に示すように、右側板5aまたは左側板5bのいずれか一方に偏って固定されることがあった。また、シャーシ5が図4(b)に示すように右側板5aおよび左側板5bが開くように変形している場合は、ねじ7、7が締め付けられると右側板5aおよび左側板5bが垂直方向に矯正されることになるが、右側板5aと左側板5bとが同じように矯正されないことがあった。   In the mounting structure of the metal fitting to the chassis, the metal fitting 6 may be fixed to either the right side plate 5a or the left side plate 5b as shown in FIG. 4A. Further, when the chassis 5 is deformed so that the right side plate 5a and the left side plate 5b are opened as shown in FIG. 4B, when the screws 7 are tightened, the right side plate 5a and the left side plate 5b are in the vertical direction. The right side plate 5a and the left side plate 5b may not be corrected in the same way.

特開2005−327981号公報に提案された電子機器装置の板金筐体構造によると、天板5の嵌合片5aに囲まれた嵌合穴5bを後面板2の差込片2aを挿入する。そして、嵌合片5aおよび天板の曲げ部内面と差込片2aおよび差込片曲げ部2b表面が挟圧保持された状態となり、後面板2に天板5が嵌め込まれて固定される。   According to the sheet metal housing structure of the electronic device apparatus proposed in Japanese Patent Application Laid-Open No. 2005-327981, the insertion piece 2a of the rear plate 2 is inserted into the fitting hole 5b surrounded by the fitting piece 5a of the top plate 5. . And the bending piece inner surface of the fitting piece 5a and the top plate and the insertion piece 2a and the insertion piece bending portion 2b are in a state of being pressed and held, and the top plate 5 is fitted into the rear plate 2 and fixed.

上記した特開2005−327981号公報に提案された電子機器装置の板金筐体構造では、後面板2と天板5との位置決めがなされないため、後面板2と天板5との相対位置が正確に決まらないという問題があった。また、後面板2と天板5とがねじ締着されていないため、強固に固定されておらず、天板5を強く引っ張ると後面板2から外れる恐れがあった。
特開2005−327981号公報、段落0013、図1、図2
In the sheet metal housing structure of the electronic device apparatus proposed in Japanese Patent Application Laid-Open No. 2005-327981, the rear plate 2 and the top plate 5 are not positioned, so the relative position between the rear plate 2 and the top plate 5 is There was a problem that it was not determined accurately. Further, since the rear plate 2 and the top plate 5 are not screwed together, they are not firmly fixed, and there is a possibility that they will come off the rear plate 2 when the top plate 5 is pulled strongly.

以下この発明を実施するための最良の形態を実施例に即して説明する。図1はこの発明の実施例であるシャーシへの金具の取付構造を示す分解斜視図である。図1に示すシャーシ1には、底板から右側板1aと左側板1bが垂直に立上がり、右側板1a、左側板1bおよび底板折曲げることにより垂直面の後板1cが底板から立上がるように形成されている。   The best mode for carrying out the present invention will be described below with reference to examples. FIG. 1 is an exploded perspective view showing a mounting structure of a metal fitting to a chassis according to an embodiment of the present invention. The chassis 1 shown in FIG. 1 is formed such that the right side plate 1a and the left side plate 1b rise vertically from the bottom plate, and the right side plate 1a, left side plate 1b and bottom plate are bent so that the rear plate 1c of the vertical surface rises from the bottom plate. Has been.

金具2は断面コ字形に形成されており、コ字形後面2aの両側から直角方向にコ字形右側面2bとコ字形左側面2cが延びている。シャーシ1の後板1cおよび右側板1aには夫々ねじ挿通穴1fおよびねじ挿通穴1eが設けられている。シャーシ1の後板1cにはさらに垂直方向に延びるスリット1dが設けられている。   The metal fitting 2 is formed in a U-shaped cross section, and a U-shaped right side surface 2b and a U-shaped left side surface 2c extend from both sides of the U-shaped rear surface 2a in a perpendicular direction. The rear plate 1c and the right side plate 1a of the chassis 1 are provided with a screw insertion hole 1f and a screw insertion hole 1e, respectively. The rear plate 1c of the chassis 1 is further provided with a slit 1d extending in the vertical direction.

金具2のコ字形後面2aには直角方向に延びる切り起こし舌片2dが設けられ、さらに、ねじ穴2gが設けられている。金具2の右側板2bには右側板2bと平行方向に延びる切り起こし舌片2eが設けられ、起こし舌片2eにねじ穴2fが設けられている。   The U-shaped rear surface 2a of the metal fitting 2 is provided with a cut-and-raised tongue piece 2d extending in a perpendicular direction, and further provided with a screw hole 2g. The right side plate 2b of the metal fitting 2 is provided with a cut-and-raised tongue piece 2e extending in a direction parallel to the right-side plate 2b, and the raised tongue piece 2e is provided with a screw hole 2f.

金具2をシャーシ1に締着するには、先ず、金具2を図示の矢印方向にシャーシ1の後部に挿入する。このとき金具2の起こし舌片2dがシャーシ1のスリット1dに嵌合して金具2のシャーシ1に対する左右方向の位置が決められる。その状態でねじ挿通穴1eの位置をねじ穴2fに合わせてねじ挿通穴1eを挿通したねじ7をねじ穴2fにねじ込む。さらに、ねじ挿通穴1fを挿通したねじ7をねじ穴2gにねじ込む。これらのねじ7、7を締付けることにより金具2がシャーシ1に対して正確に位置決めされた状態で強固に固定される。   In order to fasten the metal fitting 2 to the chassis 1, first, the metal fitting 2 is inserted into the rear portion of the chassis 1 in the direction of the arrow shown in the drawing. At this time, the raised tongue piece 2d of the metal fitting 2 is fitted into the slit 1d of the chassis 1, and the position of the metal fitting 2 in the left-right direction with respect to the chassis 1 is determined. In this state, the screw insertion hole 1e is aligned with the screw hole 2f, and the screw 7 inserted through the screw insertion hole 1e is screwed into the screw hole 2f. Further, the screw 7 inserted through the screw insertion hole 1f is screwed into the screw hole 2g. By tightening these screws 7, the metal fitting 2 is firmly fixed in a state where it is accurately positioned with respect to the chassis 1.

実施例は以上のように構成されているが発明はこれに限られず、例えば、金具2が薄く十分な強度のねじ穴を形成しにくい場合はねじ穴2gやねじ穴2fをねじ挿通穴としてねじとナットにより金具2を締着してもよい。   The embodiment is configured as described above, but the invention is not limited thereto.
