The support base 120 is configured. The circuit board 113 is fixed to the spacer 133 press-fitted and fixed to the mounting portion 1223 by using mounting screws, and the circuit board 113 is attached to the main body 2 via the support base 120.

上述のように、本実施形態では、固定部材１２１は、取付ねじ１３０のような結合部品を用いて本体２に取り付けられている。ここで、結合部品は２つの部材を結合するための部品である。結合部品は取付ねじ１３０に限定されず、スナップフィットで２つの部材を結合するような部品であってもよいし、かしめることで一部を塑性変形させることによって２つの部材を結合するリベットなどの部品でもよい。また、本実施形態では、取付ねじ１３０のような結合部品が、本体２の内側から固定部材１２１と本体２とを挟んで外付け部品（ヒートシンク７）に結合されることによって、固定部材１２１と外付け部品（ヒートシンク７）とが本体２に共締めされている。したがって、本体２に回路部品１１０を収容する方向と同じ方向から、結合部品を用いて固定部材１２１と外付け部品とを本体２に共締めする作業を行うことができ、作業性が向上するという利点もある。 As described above, in the present embodiment, the fixing member 121 is attached to the main body 2 by using a coupling component such as a mounting screw 130. Here, the connecting part is a part for joining two members. The joining part is not limited to the mounting screw 130, and may be a part that joins two members by snap-fitting, or a rivet that joins two members by plastically deforming a part by caulking. It may be a part of. Further, in the present embodiment, the connecting component such as the mounting screw 130 is coupled to the fixing member 121 from the inside of the main body 2 by sandwiching the fixing member 121 and the main body 2 and connecting to the external component (heat sink 7). An external component (heat sink 7) is fastened together with the main body 2. Therefore, it is possible to perform the work of fastening the fixing member 121 and the external component together to the main body 2 by using the coupling component from the same direction as the direction in which the circuit component 110 is housed in the main body 2, and the workability is improved. There are also advantages.

また、本実施形態では、固定部材１２１は溶接以外の方法で本体２に固定されているので、固定部材１２１を本体２に溶接で固定する場合に比べて、取付作業が容易であり、溶接の熱で本体２の表面が変色したり表面が荒れたりするのを抑制できる。また、固定部材１２１を溶接以外の方法で本体２に固定しているので、耐食性に優れているが溶接性が良好ではない高耐食鋼板を用いて本体２を作成することができ、本体２を含む筐体１の耐食性を向上させることができる。また、本体２及びカバー３を高耐食鋼板で作成しているので、１回塗りの製品でも、海岸線から５００ｍ以内の重塩害地域において屋外に設置して使用することができる。したがって、標準品と、重塩害地域での使用に対応した重塩害対応品とを１つの品番で実現できるから、筐体１の品種を削減することができる。 Further, in the present embodiment, since the fixing member 121 is fixed to the main body 2 by a method other than welding, the mounting work is easier than in the case where the fixing member 121 is fixed to the main body 2 by welding, and welding is performed. It is possible to prevent the surface of the main body 2 from being discolored or roughened by heat. Further, since the fixing member 121 is fixed to the main body 2 by a method other than welding, the main body 2 can be created by using a highly corrosion-resistant steel plate having excellent corrosion resistance but not good weldability, and the main body 2 can be formed. The corrosion resistance of the housing 1 including the housing 1 can be improved. Further, since the main body 2 and the cover 3 are made of a highly corrosion-resistant steel plate, even a single-coat product can be installed and used outdoors in a heavy salt-damaged area within 500 m from the coastline. Therefore, since the standard product and the heavy salt damage compatible product corresponding to the use in the heavy salt damage area can be realized by one product number, the number of types of the housing 1 can be reduced.

ここで、支持台１２０は、本体２の底部（後板２２）との間に収容空間７００を設けた状態で本体２に取り付けられており、この収容空間７００に２つの回路基板１１３Ｂ，１１３Ｃとスイッチング素子１１４とが配置されている。回路基板１１３Ｂは、例えば本体２の後板２２に圧入固定されたスペーサ１３４に取付ねじを用いて固定されている。回路基板１１３Ｃは、例えば回路基板１１３Ｂにスペーサ１３５を介して取り付けされている。したがって、固定部材１２１を含む支持台１２０に取り付けられる回路基板１１３Ａと本体２の後板２２との間には、２枚の回路基板１１３Ｂ，１１３Ｃが厚み方向に間隔を開けて配置されている。換言すれば、固定部材１２１に取り付けられる回路基板１１３Ａと厚み方向に重なる位置に１以上の回路基板（本実施形態では２枚の回路基板１１３Ｂ，１１３Ｃ）が配置されている。また、回路基板１１３Ｂの後側にはスイッチング素子１１４が配置されている。スイッチング素子１１４の後面は、本体２の後板２２に設けられた貫通孔を通してヒートシンク７の前面に接触しており、スイッチング素子１１４がヒートシンク７に熱的に結合されている。このように、収容空間７００には回路基板１１３Ｂ，１１３Ｃ及びスイッチング素子１１４が配置されており、スペースを有効に利用して回路部品１１０を収容することができるので、本体２の小型化を図ることができる。 Here, the support base 120 is attached to the main body 2 in a state where the accommodation space 700 is provided between the support base 120 and the bottom portion (rear plate 22) of the main body 2, and the two circuit boards 113B and 113C are attached to the accommodation space 700. A switching element 114 is arranged. The circuit board 113B is fixed to, for example, a spacer 134 press-fitted and fixed to the rear plate 22 of the main body 2 by using a mounting screw. The circuit board 113C is attached to the circuit board 113B, for example, via a spacer 135. Therefore, two circuit boards 113B and 113C are arranged at intervals in the thickness direction between the circuit board 113A attached to the support base 120 including the fixing member 121 and the rear plate 22 of the main body 2. In other words, one or more circuit boards (two circuit boards 113B and 113C in this embodiment) are arranged at positions overlapping with the circuit board 113A attached to the fixing member 121 in the thickness direction. Further, a switching element 114 is arranged on the rear side of the circuit board 113B. The rear surface of the switching element 114 is in contact with the front surface of the heat sink 7 through a through hole provided in the rear plate 22 of the main body 2, and the switching element 114 is thermally coupled to the heat sink 7. In this way, the circuit boards 113B and 113C and the switching element 114 are arranged in the accommodation space 700, and the circuit component 110 can be accommodated by effectively utilizing the space. Therefore, the main body 2 should be miniaturized. Can be done.

本実施形態の筐体１は取付部材８を用いて壁３００に取り付けられる。取付部材８は、壁３００にねじなどで固定される背板８１と、背板８１の左側縁及び右側縁からそれぞれ前方に突出する横ガード８２と、背板８１の下側縁から前方に突出する下ガード８３とを備える。 The housing 1 of the present embodiment is attached to the wall 300 by using the attachment member 8. The mounting member 8 includes a back plate 81 fixed to the wall 300 with screws or the like, a lateral guard 82 projecting forward from the left and right edges of the back plate 81, and a lateral guard 82 projecting forward from the lower edge of the back plate 81. It is provided with a lower guard 83.

背板８１には、壁３００に固定するためのねじを通す複数の孔８４が設けられている。背板８１は、複数の孔８４にそれぞれ通されたねじを用いて壁３００に固定される。背板８１の上側縁には、ヒートシンク７の後面と保持板１４との間の隙間に挿入される挿入片８８が設けられている。また、背板８１には、筐体１が取付部材８に取り付けられた状態で、突出部４に設けられた電線挿入口４３に繋がる貫通孔８６が設けられている。 The back plate 81 is provided with a plurality of holes 84 through which screws for fixing to the wall 300 are passed. The back plate 81 is fixed to the wall 300 using screws that have been passed through the plurality of holes 84, respectively. An insertion piece 88 to be inserted into a gap between the rear surface of the heat sink 7 and the holding plate 14 is provided on the upper edge of the back plate 81. Further, the back plate 81 is provided with a through hole 86 connected to the electric wire insertion port 43 provided in the protruding portion 4 in a state where the housing 1 is attached to the attachment member 8.

壁３００に固定された取付部材８の上側から筐体１を取付部材８に取り付け、ヒートシンク７の後面と保持板１４との間の隙間に取付部材８の挿入片８８を挿入させると、取付部材８に筐体１が保持される。筐体１が取付部材８に保持された状態では、ヒートシンク兼用ケース６の側面が横ガード８２によって覆われ、ヒートシンク兼用ケース６及びヒートシンク７の下面が下ガード８３によって覆われる。したがって、取付部材８に設けられた横ガード８２及び下ガード８３によって、高温になるヒートシンク兼用ケース６及びヒートシンク７にユーザが触れる可能性を低減できる。横ガード８２及び下ガード８３は、本体２を壁３００に取り付けるための取付部材８に一体に設けられているので、部品の数を削減できる。また筐体１の施工時又は分解時に作業が必要になる部品の数が少なくなるので、作業性が向上するという利点もある。 When the housing 1 is attached to the attachment member 8 from above the attachment member 8 fixed to the wall 300, and the insertion piece 88 of the attachment member 8 is inserted into the gap between the rear surface of the heat sink 7 and the holding plate 14, the attachment member 8 is inserted. The housing 1 is held in 8. In the state where the housing 1 is held by the mounting member 8, the side surface of the heat sink combined case 6 is covered by the lateral guard 82, and the lower surfaces of the heat sink combined case 6 and the heat sink 7 are covered by the lower guard 83. Therefore, the lateral guard 82 and the lower guard 83 provided on the mounting member 8 can reduce the possibility that the user touches the heat sink combined case 6 and the heat sink 7, which become hot. Since the lateral guard 82 and the lower guard 83 are integrally provided with the mounting member 8 for mounting the main body 2 to the wall 300, the number of parts can be reduced. Further, since the number of parts that require work during construction or disassembly of the housing 1 is reduced, there is an advantage that workability is improved.

また、取付部材８には、ヒートシンク兼用ケース６及びヒートシンク７の上面を覆う上ガード９が固定される。上ガード９の左右両側には、取付ねじを通すための挿通孔９２が設けられている。取付部材８の左右の横ガード８２には、上ガード９の挿通孔９２に対応する部位にねじ孔８９が設けられている。上ガード９は、挿通孔９２に通した固定ねじを横ガード８２のねじ孔８９にねじ込むことによって、取付部材８に固定される。上ガード９が取付部材８に固定された状態では、上ガード９でヒートシンク兼用ケース６及びヒートシンク７の上面が覆われるので、高温になるヒートシンク兼用ケース６及びヒートシンク７の上面にユーザが触れる可能性を低減できる。この上ガード９は、金属部品の表面を樹脂材料で覆うことによって形成されている。上ガード９の表面は樹脂材料で覆われているので、上ガード９の表面が樹脂材料で覆われていない場合に比べて、ヒートシンク兼用ケース６及びヒートシンク７などの許容外郭温度を高めに設定できる。 Further, an upper guard 9 that covers the upper surface of the heat sink combined case 6 and the heat sink 7 is fixed to the mounting member 8. Insertion holes 92 for passing mounting screws are provided on both the left and right sides of the upper guard 9. The left and right lateral guards 82 of the mounting member 8 are provided with screw holes 89 at locations corresponding to the insertion holes 92 of the upper guard 9. The upper guard 9 is fixed to the mounting member 8 by screwing the fixing screw passed through the insertion hole 92 into the screw hole 89 of the lateral guard 82. When the upper guard 9 is fixed to the mounting member 8, the upper guard 9 covers the upper surfaces of the heat sink combined case 6 and the heat sink 7, so that the user may touch the upper surfaces of the heat sink combined case 6 and the heat sink 7, which become hot. Can be reduced. The upper guard 9 is formed by covering the surface of the metal part with a resin material. Since the surface of the upper guard 9 is covered with the resin material, the allowable outer temperature of the heat sink combined case 6 and the heat sink 7 can be set higher than that when the surface of the upper guard 9 is not covered with the resin material. ..

上述のように、本実施形態では、本体２に収容される複数の回路部品１１０が発熱部品（例えばスイッチング素子１１４など）を含んでいる。そして、固定部材１２１と共に本体２に共締めされる外付け部品は、発熱部品（例えばスイッチング素子１１４）と熱的に結合される放熱部品（例えばヒートシンク７）を含んでいる。本実施形態では、放熱部品と固定部材１２１とを本体２に対して共締めしているので、放熱部品と固定部材１２１とを別々に本体２に固定する場合に比べて、放熱部品及び固定部材１２１を本体２に固定するための部品の数を減らすことができる。 As described above, in the present embodiment, the plurality of circuit components 110 housed in the main body 2 include heat generating components (for example, a switching element 114). The external component that is fastened together with the fixing member 121 to the main body 2 includes a heat radiating component (for example, a heat sink 7) that is thermally coupled to a heat generating component (for example, a switching element 114). In the present embodiment, since the heat radiating component and the fixing member 121 are fastened together with the main body 2, the heat radiating component and the fixing member are compared with the case where the heat radiating component and the fixing member 121 are separately fixed to the main body 2. The number of parts for fixing the 121 to the main body 2 can be reduced.

また、本実施形態では、固定部材１２１を用いて本体２に取り付けられる一部の回路部品が、電気回路（例えば電力変換回路１０１）の少なくとも一部が形成された回路基板１１３を含んでいる。したがって、本実施形態では、固定部材１２１を介して回路基板１１３を本体２に取り付けることができる。 Further, in the present embodiment, some circuit components attached to the main body 2 using the fixing member 121 include a circuit board 113 on which at least a part of an electric circuit (for example, a power conversion circuit 101) is formed. Therefore, in the present embodiment, the circuit board 113 can be attached to the main body 2 via the fixing member 121.

（３．１）変形例１
変形例１の筐体１が備える本体２Ａについて図８及び図９を参照して説明する。なお、本体２Ａ以外の構成は上記実施形態の電力変換装置１００と同様であるので、共通する構成要素には同一の符号を付して、その説明は省略する。 (3.1) Modification 1
The main body 2A included in the housing 1 of the modified example 1 will be described with reference to FIGS. 8 and 9. Since the configurations other than the main body 2A are the same as those of the power conversion device 100 of the above embodiment, the common components are designated by the same reference numerals, and the description thereof will be omitted.

変形例１の本体２Ａでは、下側の側板２３の後部に複数の丸孔２３１が左右方向に沿って設けられている。複数の丸孔２３１には電線管６００が接続され、電線管６００内の電線が丸孔２３１を通して本体２Ａの内部に挿入され、本体２Ａの内部に収容された回路部品に接続される。ここで、下側の側板２３には、前端部から丸孔２３１が設けられた部位の前側まで凹部２８が設けられている。本体２Ａには、図９に示すように、左右の側板２３の間を連結する板状の連結板２９が例えばねじなどの締結部材を用いて取り付けられており、この連結板２９を用いて凹部２８が閉塞される。 In the main body 2A of the modified example 1, a plurality of round holes 231 are provided in the rear portion of the lower side plate 23 along the left-right direction. The electric wire tube 600 is connected to the plurality of round holes 231 and the electric wire in the electric wire tube 600 is inserted into the main body 2A through the round hole 231 and connected to the circuit component housed inside the main body 2A. Here, the lower side plate 23 is provided with a recess 28 from the front end portion to the front side of the portion where the round hole 231 is provided. As shown in FIG. 9, a plate-shaped connecting plate 29 that connects between the left and right side plates 23 is attached to the main body 2A by using a fastening member such as a screw, and the concave portion 29 is used by using the connecting plate 29. 28 is blocked.

変形例１の本体２Ａに電線管６００を用いて配線する場合、本体２Ａから連結板２９を取り外した状態で、丸孔２３１に電線管６００を接続し、電線管６００内の電線を本体２Ａ内に挿入して、本体２Ａの内部に収容された回路部品に接続する。その後、本体２Ａに連結板２９を取り付け、本体２Ａにカバー３を取り付けることによって筐体１が組み立てられる。 When wiring to the main body 2A of the modified example 1 using the electric wire tube 600, the electric wire tube 600 is connected to the round hole 231 with the connecting plate 29 removed from the main body 2A, and the electric wire in the electric wire tube 600 is inside the main body 2A.
