Description

空冷式めっき用電源装置における冷却用ファンのファンカバーの係止構造に関する。   The present invention relates to a locking structure of a fan cover of a cooling fan in an air-cooling type plating power supply device.

めっき用電源装置は酸性あるいはアルカリ性のめっき槽の近傍で使用されることが多く，前記の電源装置が空冷式電源装置である場合は，使用される冷却ファンには常時腐食性ガスを含んだ空気が通流することになり，汚損がひどく，冷却用ファンは保守交換の対象部品となっている。   The power supply for plating is often used in the vicinity of an acidic or alkaline plating tank. When the power supply is an air-cooled power supply, the cooling fan used is always air containing corrosive gas. The cooling fan is a target part for maintenance and replacement.

従来のこの種の技術としては特許文献１にファンカバーが開示されている。さらに、図３に従来の空冷式めっき用電源装置を示す。図３において，冷却用ファンはめっき用電源装置１の裏面パネル１４の内側に配置され，裏面パネル１４に開口部１５を設けて冷却用空気を排出あるいは吸入している。裏面パネル１４の外面側には，入出力配線用端子台１２及び制御配線用端子台１３が設けられ，裏面パネル１４は取り外す構造にはなっておらず，筐体２と一体になっている。従って，冷却ファンを保守交換するために，裏面パネル１４は保守交換に必要な寸法で冷却ファン４に対応する部分をカットしている。裏面パネル１４のカットした部分にはカット部１７を覆うファンカバー３を取り付ける。ファンカバー３には，前述した冷却用空気を排出あるいは吸入するための開口部１５を設けている。   As a conventional technique of this type, a fan cover is disclosed in Patent Document 1. Further, FIG. 3 shows a conventional power supply device for air-cooling plating. In FIG. 3, the cooling fan is disposed inside the back panel 14 of the plating power supply 1, and an opening 15 is provided in the back panel 14 to discharge or suck cooling air. An input / output wiring terminal block 12 and a control wiring terminal block 13 are provided on the outer surface side of the back panel 14, and the back panel 14 is not structured to be removed but is integrated with the housing 2. Therefore, in order to perform maintenance replacement of the cooling fan, the back panel 14 is cut at a portion corresponding to the cooling fan 4 with dimensions necessary for maintenance replacement. The fan cover 3 that covers the cut portion 17 is attached to the cut portion of the back panel 14. The fan cover 3 is provided with an opening 15 for discharging or sucking the cooling air described above.

従来，ファンカバー３はねじ止めで固定されてあり，前記の冷却ファン４を保守交換するときには，ファンカバー３を取り外してから保守交換をすることになるが，めっき用直流電源装置１は前述のように悪環境下で使用されることが多いため，前記のファンカバー３を固定するねじ１１が腐食し，前記のねじ１１の頭部の十字穴がつぶれて，ねじ１１を緩めることができなくなり，ファンカバー３を取り外して冷却ファン４を保守交換することができなくなる場合があった。   Conventionally, the fan cover 3 is fixed with screws, and when the cooling fan 4 is to be maintained and replaced, the fan cover 3 must be removed and then replaced. Since the screw 11 for fixing the fan cover 3 is corroded, the cross hole in the head of the screw 11 is crushed and the screw 11 cannot be loosened. In some cases, the fan cover 3 is removed and the cooling fan 4 cannot be replaced for maintenance.

「特開平８−５１５４号」公報，「暖房機のファンカバー」“JP-A-8-5154”, “Fan cover of a heater”

悪環境下で使用されるめっき用電源装置の裏面パネルのファンカバーを固定するねじが腐食して，ねじの頭部の十字穴がつぶれ，ねじを緩めることができなくなり，冷却ファンの保守交換ができなくなる点である。   The screws that fix the fan cover on the rear panel of the power supply for plating used in adverse environments corrode, the cross holes in the screw heads are crushed, and the screws cannot be loosened, so that the cooling fan can be serviced and replaced. It is a point that cannot be done.

めっき用電源装置の筐体及びファンカバーを樹脂製とし，ファンカバーと筐体との係止構造において，樹脂の弾性を利用した係止爪をカバーに設けて，ねじを使用することなくファンカバーと筐体を固定する。   The housing and fan cover of the power supply device for plating are made of resin. In the locking structure between the fan cover and the housing, a locking claw that uses the elasticity of the resin is provided on the cover, and the fan cover can be used without using screws. And fix the housing.

ねじを使用しなくなり，めっき用電源装置を悪環境下で使用しても，ファンカバーを固定するねじが腐食することはなくなり，ねじの頭部の十字穴がつぶれてねじを緩めることができなくなり，ファンカバーを取り外せなく，冷却ファンの保守交換ができなくなることがなくなった。ねじを緩める作業がなくなり，マイナスドライバーなどで前記の係止爪をおさえることによりファンカバーを取り外すことができ，ファンの保守交換を簡単に行える。   Even if the screw is not used and the power supply for plating is used in a bad environment, the screw that secures the fan cover will not be corroded, and the cross hole in the head of the screw will be crushed and the screw cannot be loosened. The fan cover can no longer be removed, and the cooling fan can no longer be serviced or replaced. There is no need to loosen the screws, and the fan cover can be removed by holding the locking claws with a flat-blade screwdriver, making it easy to maintain and replace the fan.

ファンカバーをめっき用電源装置の筐体へ簡単に装着し取り外すという目的を，部品点数と作業工数を削減した上で実現した。   The purpose of easily attaching and removing the fan cover to the plating power supply housing was achieved while reducing the number of parts and the number of work steps.

図１は本発明の実施例であって，めっき用電源装置１の裏面パネル１４の内側に冷却ファン４を配置している。裏面パネル１４の冷却ファン４の配置位置に対応する部分には，冷却ファン４の保守交換をするために必要な寸法で一部をカットしている。裏面パネル１４のカットした部分にはカット部１７を覆うファンカバー３を取り付ける。ファンカバー３には，冷却用空気を排出あるいは吸入するための開口部１５を配置している。尚、筐体２とファンカバー３はともに樹脂で形成されている。   FIG. 1 shows an embodiment of the present invention, in which a cooling fan 4 is arranged inside a back panel 14 of a power supply device 1 for plating. A part of the back panel 14 corresponding to the arrangement position of the cooling fan 4 is partially cut to a size necessary for maintenance and replacement of the cooling fan 4. The fan cover 3 that covers the cut portion 17 is attached to the cut portion of the back panel 14. The fan cover 3 is provided with an opening 15 for discharging or sucking cooling air. Both the housing 2 and the fan cover 3 are made of resin.

ファンカバー３と筐体２との係止の構造は，一部を引っ掛け１０とし，一部を樹脂の弾性を利用した係止爪６による嵌め合い構造とし，本実施例ではともに２箇所で行っている。   The structure of locking the fan cover 3 and the housing 2 is partly a hook 10 and partly a fitting structure with a locking claw 6 using the elasticity of the resin. ing.

図２に筐体２の係止部５及びファンカバー３の係止爪６の構造を断面図を用いて説明する。図２の（１）は，筐体２の係止部５の説明図で，係止溝８を設けている。図２の（２）は，ファンカバー３の係止爪６の構造の説明図で，折り返した形状の係止爪６と係止爪６上に突起７を形成している。ファンカバー３を筐体２に嵌め合わせると，図２の（１）に破線で表しているようにファンカバー３の突起７が筐体２の係止溝８に嵌り，ファンカバー３は筐体２に係止する。   2A and 2B, the structure of the locking portion 5 of the housing 2 and the locking claws 6 of the fan cover 3 will be described with reference to cross-sectional views. FIG. 2 (1) is an explanatory view of the locking portion 5 of the housing 2 and is provided with a locking groove 8. FIG. 2 (2) is an explanatory view of the structure of the locking claw 6 of the fan cover 3, and the projection 7 is formed on the locking claw 6 in the folded shape and the locking claw 6. When the fan cover 3 is fitted to the housing 2, the projection 7 of the fan cover 3 fits into the locking groove 8 of the housing 2 as indicated by a broken line in FIG. Lock to 2.

ファンカバー３の係止爪６は，突起部７から係止爪６の先端部１８までの外方に向かう部分は，ファンカバー３を筐体２に係合させたとき，筐体との間に隙間９を生じるように，筐体２の係止部５との接触面よりも厚みを薄く形成している。   The engaging claw 6 of the fan cover 3 has an outwardly extending portion from the protrusion 7 to the tip 18 of the engaging claw 6 when the fan cover 3 is engaged with the casing 2. The gap 9 is formed thinner than the contact surface of the housing 2 with the locking portion 5.

ファンカバー３を取り外す場合は，筐体２の係止部５とファンカバー３の係止爪６との隙間９にマイナスドライバ−１６のようなもので係止爪６を押さえて，係止爪６の突起７を筐体２の係止部５の係止溝８から離し，ファンカバー３の筐体２との係止を解除し，ファンカバー３を取り外す。   When the fan cover 3 is to be removed, the locking claw 6 is held in the gap 9 between the locking portion 5 of the housing 2 and the locking claw 6 of the fan cover 3 with a flat screwdriver-16, so that the locking claw 6 is separated from the locking groove 8 of the locking portion 5 of the housing 2, the locking of the fan cover 3 with the housing 2 is released, and the fan cover 3 is removed.

本発明はめっき用電源装置を対象としたが，めっき用電源装置以外の電源装置や電気装置であっても，冷却ファンの保守交換用窓のカバーの係止構造として活用できる。 さらに，保守交換の対象は冷却ファンだけには限らず，半導体素子・ヒューズ・制御用プリント基板など他の保守交換を要する部品に対する保守交換操作用の窓のカバーに対する係止構造として利用できる。   Although the present invention is directed to the power supply device for plating, a power supply device or an electric device other than the power supply device for plating can also be used as a latching structure for the cover for maintenance and replacement of the cooling fan. Furthermore, the object of maintenance replacement is not limited to the cooling fan, but can be used as a locking structure for a window cover for maintenance replacement operation for other parts requiring maintenance replacement, such as semiconductor elements, fuses, and control printed circuit boards.
