【考案の詳細な説明】 この考案は、閉鎖配電盤の開閉扉への取付加工を容易に
するとともに、安価にできるようにした閉鎖配電盤の操
作小窓に関する。[Detailed Description of the Invention] This invention relates to a small operating window for a closed power distribution board that is easy to attach to the opening/closing door of the closed power distribution board and can be manufactured at low cost.

一般に、閉鎖配電盤内の機器を外部より操作するため、
第１図に示すように、閉鎖配電盤１の前面の開閉自在な
開閉扉２に、操作小窓３が設けられ、開閉自在な操作扉
４が設けられている。Generally, in order to operate equipment inside a closed switchboard from the outside,
As shown in FIG. 1, a small operation window 3 is provided in a door 2 that can be opened and closed at the front of a closed switchboard 1, and an operation door 4 that can be opened and closed is provided.

そして、従来の閉鎖配電盤の操作小窓は、第２図に示す
ように、開閉扉２に操作用の穴５を透設し、その穴５の
周縁の前面に、断面り字状の帯状の水切板が、その一端

れ、操作扉８の内面に、水切板６の他端寄りの接合面６
′に当接自在なバッキング９が固着されている。As shown in Fig. 2, the conventional small operation window of a closed switchboard has a hole 5 for operation transparently provided in the opening/closing door 2, and a belt-shaped strip with an angular cross section on the front side of the periphery of the hole 5. A drain plate is provided by fully welding one end of the drain plate.Furthermore, an operation door 8 is provided on the outside of the hole 5 with a rainproof cover 7 attached to the periphery so as to be openable and closable. Joint surface 6 near the other end of 6
A backing 9 that can freely come into contact with is fixed to '.

そして、水切板６、バッキング９および防雨棧７により
、配電盤１内への水の侵入が防止されるとともに、配電
盤１内への塵の侵入が防止されている。The draining plate 6, the backing 9, and the rainproof cover 7 prevent water from entering the switchboard 1, and also prevent dust from entering the switchboard 1.

しかし、前記従来の操作小窓は、穴５０周縁に水切板６
を全溶接するため、その作業工数および穴５と水切板６
との溶接部の歪修正工数が非常に多くなる欠点があり、
さらに、配電盤１内の熱が水切板６より直接にバッキン
グ９に伝わるため、バンキング９が変形し、バッキング
９と水切板６との接合が不十分になる危険性がある。However, the conventional small operation window has a drainage plate 6 at the periphery of the hole 50.
In order to fully weld the holes 5 and drain plates 6,
The disadvantage is that it takes a lot of man-hours to correct the distortion of the welded part.
Furthermore, since the heat within the switchboard 1 is directly transmitted to the backing 9 from the drain plate 6, there is a risk that the banking 9 may be deformed and the bond between the backing 9 and the drain plate 6 may become insufficient.

この考案は、以上の点に留意してなされたものであり、
つぎにこの考案を、その１実施例を示した第３図以下の
図面とともに詳細に説明する。This idea was made with the above points in mind,
Next, this invention will be explained in detail with reference to the drawings from FIG. 3 showing one embodiment thereof.

これらの図面において、第２図と同一記号のものは同一

。In these drawings, the same symbols as those in FIG. 2 indicate the same or corresponding parts, and 10 is a U-shaped cross-section with an inward bulge 11 having a cross-sectional shape formed at one end edge. main banking made of chloroprene, neoprene, etc., 12 is a belt-shaped sheet metal with a U-shaped cross section embedded in the main backing 10, 1
Reference numeral 3 denotes a sub-backing having a U-shaped cross section and bonded to the inner and outer sides of the other piece of the main banking 10, and 14 an inverted C-shaped joint formed integrally with the outer end of the sub-backing 13.

そして、開閉扉２に透設された操作用の穴５の周縁に、
接合部１４を外側に位置させて主バッキング１０のＵ字
状の両片を嵌入し、開閉自在な操作扉８を接合部１４に
当接自在にして操作窓３を形成している。Then, on the periphery of the operation hole 5 transparently provided in the opening/closing door 2,
The joint part 14 is located on the outside, and both U-shaped pieces of the main backing 10 are fitted, and the operation door 8, which can be opened and closed, can freely come into contact with the joint part 14 to form the operation window 3.

したがって、操作窓３′の開閉扉２への加工は、操作用
の穴５のみでよく、水切板および水切板の溶接工数を不
要にするとともに、溶接後の歪修正工数をなくすことが
できるため、操作窓３′の製作を容易にするとともに、
安価にすることができる。Therefore, only the operation hole 5 is required for processing the operation window 3' on the opening/closing door 2, which eliminates the need for welding the drain plate and the man-hour for welding the drain plate, as well as eliminating the need for distortion correction after welding. , facilitates the production of the operation window 3', and
It can be made cheap.

また、主バッキング１０に板金１２が埋設されるため、
主バッキング１０の穴５の周縁への取付けが確実になさ
れる。In addition, since the sheet metal 12 is embedded in the main backing 10,
Attachment to the periphery of the hole 5 of the main backing 10 is ensured.

さらに、主バッキング１０に接着された副バッキング１

され、防水、防塵仕様に十分適用することができる。Furthermore, a secondary backing 1 adhered to the main backing 10
3 is brought into contact with the inner surface of the operation door 8, but since the heat inside the switchboard 1 is not directly transmitted to the joint 14 from the opening/closing □ 2, the joint 14 may be deformed by the heat. Therefore, the joint portion 14 and the operation door 8 are always properly joined, and the device can be sufficiently applied to waterproof and dustproof specifications.

、従来の水切板の機能をも有するものである。Note that the joint part 14 at the end of the sub-backing 13 is formed facing outward;
This is to prevent water from entering through the joint surface with the drain plate, and also has the function of a conventional drain plate.

も十分適用することができる。As described above, according to the small operation window of the closed switchboard of this invention, a strip-shaped sheet metal with a U-shaped cross section is embedded in the main backing with a U-shaped cross section, and one edge of the main backing has a cross-section of form an inward bulge, adhere a sub backing with a U-shaped cross section to the inside and outside of the other piece of the main backing, and integrate an inverted C-shaped joint at the outer end of the sub backing. It takes shape,
A transparent operation hole is made in the opening/closing door of the closed switchboard, and the joint part is positioned on the outside around the hole, and both U-shaped pieces of the main backing are inserted, so that it can be opened and closed freely on the outside of the hole. By making the inner surface of the operation door able to come into contact with the joint, the conventionally used drain plate is no longer necessary, and the installation welding and distortion correction man-hours can be eliminated, making it cheaper. It can be fully applied even in waterproof and dustproof specifications.
