【００１０】このサブパネル２は金属性部材を屈曲形成してなる。サブパネル２の上縁面２ −１はＬ字状に前面側へ折り曲げられている。上縁面２−１にはその垂直方向面２−１３と水平方向面２−１４との基部に所定間隔を隔ててフック２−１１，２ −１２が前面側へ立ち上げられている。フック２−１１，２−１２の形状は図３（ｃ）に記されている。0010 This sub-panel 2 is formed by bending a metal member. Upper edge surface 2 of sub panel 2 -1 is bent toward the front side in an L shape. The upper edge surface 2-1 has its vertical surface. Hooks 2-11 and 2 are placed at a predetermined interval at the base of 2-13 and the horizontal surface 2-14. -12 is raised towards the front side. The shapes of hooks 2-11 and 2-12 are shown in Figure 3. (c).

【００１１】すなわち、そのフック部２−１１ａ，２−１２ａが互いに外方向を向くものとされており、フック部２−１１ａ，２−１２ａと水平方向面２−１４との間に保護カバー１の絶縁紙厚ｔよりも若干大きい隙間ｈが設けられている。また、フック２−１１，２−１２の幅Ｗ１は、保護カバー１における角孔１−３１，１−３２の幅Ｗ２よりも若干小さいものとされている。また、フック部２−１１ａと２ −１２ａとの端部間距離Ｌ１は、保護カバー１における角孔１−３１と１−３２との端部間距離Ｌ２よりも若干長くされている。[0011] That is, the hook portions 2-11a and 2-12a are directed outward from each other. 2-11a, 2-12a and the horizontal surface 2-14. A gap h is provided which is slightly larger than the thickness t of the insulating paper of the protective cover 1. Also, the foot The width W1 of the square holes 1-31, 1-3 in the protective cover 1 is This width is slightly smaller than the width W2 of No. 2. In addition, the hook portions 2-11a and 2 -12a is the distance L1 between the square holes 1-31 and 1-32 in the protective cover 1. The end-to-end distance L2 is slightly longer than the end-to-end distance L2.

And this For the sub-panel 2 where the printed circuit board 3 is arranged, A protective cover 1 is attached to protect the electronic circuits that have been removed. Figure 1 shows how to install the protective cover 1. Indicates the installation status.

【００１３】保護カバー１の取り付けは次のようにして行う。[0013] The protective cover 1 is attached as follows.

【００１４】先ず、保護カバー１の角孔１−３１をサブパネル２のフック２−１１に遊挿する（図５（ａ）参照）。すなわち、第１の移動位置にて、角孔１−３１をフック２−１１に遊挿する。この場合、そのＬ１寸法とＬ２寸法との関係から、角孔１ −３２はフック２−１２へ簡単には遊挿できない。[0014] First, loosely insert the square hole 1-31 of the protective cover 1 into the hook 2-11 of the sub panel 2. (See Figure 5(a)). That is, the square hole 1-31 is hooked at the first movement position. Insert it loosely into 2-11. In this case, from the relationship between the L1 dimension and L2 dimension, the square hole 1 -32 cannot be easily inserted loosely into hook 2-12.

【００１５】次に、角孔１−３１をフック２−１１に遊挿した状態で、保護カバー１を図５（ａ）における左方向へずらし、同図（ｂ）に示すように、角孔１−３２をフック２−１２に遊挿する。すなわち、第２の移動位置にて、角孔１−３２をフック２−１２に遊挿する。[0015] Next, with the square hole 1-31 loosely inserted into the hook 2-11, the protective cover 1 is inserted as shown in FIG. Shift it to the left in (a) and insert the square hole 1-32 into the hook as shown in (b). 2-12. That is, at the second movement position, the square hole 1-32 is hooked. Insert it loosely into 2-12.

【００１６】そして、角孔１−３１および１−３２をフック２−１１および２−１２に遊挿した状態で、保護カバー１を図５（ｂ）における右方向へずらし、同図（ｃ）に示すように、前面方向への抜け防止位置とする。この抜け防止位置にて、保護カバー１の縁面１−１，１−２を図１に示すようにプリント基板３に登載された部品（コンデンサ部品３−１，端子台３−２等）の間に差し込み、保護カバー１の左右方向への移動を規制させる。[0016] Then, square holes 1-31 and 1-32 are loosely inserted into hooks 2-11 and 2-12. 5(b), move the protective cover 1 to the right in FIG. 5(c). As shown, the position is to prevent it from coming off in the front direction. In this position to prevent the protective cover from falling off. The edge surfaces 1-1 and 1-2 of the bar 1 are mounted on the printed circuit board 3 as shown in FIG. (capacitor parts 3-1, terminal block 3-2, etc.), and Restricts movement in the left and right direction.

【００１７】図６は実際の機器における保護カバー１，サブパネル２，プリント基板３の組み込み状況を示し、同図（ａ）はその平面図、同図（ｂ）はその一部を破断して示した正面図，同図（ｃ）はその一部を破断して示した側面図である。同図において、４はケース本体、５はカバーであり、プリント基板３の配置されたサブパネル２に対して、プリント基板３に構築された電子回路を保護すべく保護カバー１が上述の要領で取り付けられている。[0017] Figure 6 shows the assembly of the protective cover 1, sub-panel 2, and printed circuit board 3 in an actual device. Figure (a) is a plan view, and Figure (b) is a partially cutaway view showing the penetration situation. The front view shown in FIG. 2 is a front view, and FIG. In the same figure 4 is the case body, 5 is the cover, and the sub-part where the printed circuit board 3 is arranged. A protective cover is attached to the panel 2 to protect the electronic circuit built on the printed circuit board 3. 1 is attached in the manner described above.

【００１８】なお、上述した実施例においては、保護カバー１の縁面１−１，１−２をプリント基板３に登載された部品の間に差し込んで保護カバー１の左右方向への移動を規制するものとしたが、例えば、プリント基板３に孔を開け、保護カバー１の縁面１−１，１−２の先端に突起を設け、この突起をプリント基板３に開設した孔に差し込む構造とするようにしてもよい。また、プリント基板３の左右に図７に示すように部材６を配置し、この部材６，６の溝６−１，６−１に保護カバー１の縁面１−１，１−２を差し込んでもよい。[0018] In addition, in the embodiment described above, the edge surfaces 1-1 and 1-2 of the protective cover 1 are to move the protective cover 1 in the left-right direction by inserting it between the components mounted on the main board 3. For example, by drilling a hole in the printed circuit board 3 and Protrusions were provided at the tips of edge surfaces 1-1 and 1-2, and these protrusions were provided on the printed circuit board 3. It may also be structured to be inserted into a hole. Also, on the left and right sides of the printed circuit board 3, Arrange the member 6 as shown in the figure, and insert protective covers into the grooves 6-1, 6-1 of the members 6, 6. You may insert the edge surfaces 1-1 and 1-2 of 1.

【００１９】また、上述した実施例においては、保護カバー１の縁面１−１，１−２の両方を係止部としたが、縁面１−１，１−２の何れか一方のみを係止部としてもよい。すなわち、縁面１−１，１−２の何れか一方に対して、部材６等を設ける構造としてもよい。[0019] Moreover, in the embodiment described above, both edge surfaces 1-1 and 1-2 of the protective cover 1 is used as a locking part, but only one of the edge surfaces 1-1 and 1-2 may be used as a locking part. . That is, a structure in which the member 6 etc. is provided on either one of the edge surfaces 1-1 and 1-2. You can also use it as

【００２０】また、上述した実施例においては、保護カバー１に角孔１−３１，１−３２を設け、サブパネル２にフック２−１１，２−１２を設けるものとしたが、保護カバー１にフックを、サブパネル２に角孔を設けるものとしてもよく、係合部および掛合部の形状は他にも種々考えられる。[0020] Furthermore, in the embodiment described above, the protective cover 1 has square holes 1-31 and 1-32. hooks 2-11 and 2-12 were installed on the sub-panel 2, but the protective cover was A hook may be provided on the bar 1 and a square hole may be provided on the sub-panel 2. Various other shapes can be considered for the engaging portion.

[Effect of the idea]

以上説明したことから明らかなように本考案によれば、第１および第２の係合部を第１および第２の掛合部に遊挿した状態でずらすことにより、前面方向への抜け防止位置を得、この抜け防止位置に係止部を利用してその移動位置を規制し得るので、保護状況にある例えば電子回路の調整等を行う際に止め螺子を外すなどの手間が不要となり、従来に比してメンテナンスが容易となり、かつメンテナンスの際の安全性も確保されるものとなる。 As is clear from the above explanation, according to the present invention, the first and second engagement By sliding the part loosely inserted into the first and second engaging parts, it is possible to move it in the front direction. Obtain a position to prevent it from coming off, and use a locking part at this position to restrict its movement position. Do not remove the set screws when making adjustments to electronic circuits under protected conditions. This eliminates the need for maintenance, makes maintenance easier than before, and reduces maintenance costs. This will also ensure safety during operations.
