特開平7−198171号公報JP-A-7-198171

ところで、端子台は、折曲部にねじ止めで取り付けられるが、このねじ止めの際、端子台が回転することがある。このため、端子台の取付け作業に手間を要していた。
本発明はこのような事情に鑑みてなされたものであり、その目的は、端子台を容易に取り付けることができる空気調和機の室外機を提供することにある。
By the way, the terminal block is attached to the bent portion with screws, but the terminal block may rotate during the screwing. For this reason, it took time and labor to install the terminal block.
This invention is made | formed in view of such a situation, The objective is to provide the outdoor unit of the air conditioner which can attach a terminal block easily.

課題を解決する空気調和機の室外機は、室外機ケーシングと、この室外機ケーシングに収容される機器と、電源配線及び信号配線の少なくとも一方が接続される端子台とを備え、前記端子台は、ねじが挿通する貫通孔と、下面に設けられた凸部とを有し、前記室外機ケーシングの側板は、内側への折り曲げにより構成された折曲部を有し、前記折曲部には、前記端子台の前記貫通孔に対応するねじ孔と、前記端子台の前記凸部が係合する係合部とが設けられ、前記端子台は、前記凸部が前記折曲部の前記係合部に係合し、前記貫通孔と前記ねじ孔との連通孔にねじがねじ入れられることにより、前記折曲部に取り付けられている。   An outdoor unit of an air conditioner that solves the problem includes an outdoor unit casing, a device accommodated in the outdoor unit casing, and a terminal block to which at least one of a power supply wiring and a signal wiring is connected. The through-hole through which the screw is inserted and the convex portion provided on the lower surface, the side plate of the outdoor unit casing has a bent portion formed by inward bending, and the bent portion includes A screw hole corresponding to the through hole of the terminal block, and an engaging portion with which the convex portion of the terminal block engages, wherein the convex portion of the terminal block is the engagement of the bent portion. The screw is screwed into the communication hole between the through hole and the screw hole, and is attached to the bent portion.

この構成では、端子台を折曲部に取り付けるとき、折曲部のねじ孔と端子台の貫通孔との連通孔にねじがねじ入れられることにより、端子台が折曲部に取り付けられる。そして、この取付けの際、端子台の凸部を係合部に係合させることができるため、端子台の回転が抑制される。これにより、端子台を容易に取り付けることができる。   In this configuration, when the terminal block is attached to the bent portion, the terminal block is attached to the bent portion by screwing the screw into the communication hole between the screw hole of the bent portion and the through hole of the terminal block. And since the convex part of a terminal block can be engaged with an engaging part in the case of this attachment, rotation of a terminal block is suppressed. Thereby, a terminal block can be attached easily.

上記構成の空気調和機の室外機において、前記折曲部には、前記端子台の側面下端部に当接するガイドが少なくとも1つ設けられていることが好ましい。
端子台の取付け作業を容易とするために、端子台に凸部を設けている。この凸部は端子台の下面にあるため、端子台を折曲部に取り付けるときは、この凸部を直接視認することができない。このため、この凸部を係合部に係合しにくい場合がある。そうすると、端子台をねじ止めする前段階の作業、すなわち端子台を所定の位置に配置することに時間を要するといった事態が生じる。
In the outdoor unit for an air conditioner having the above-described configuration, it is preferable that at least one guide that contacts the lower end of the side surface of the terminal block is provided in the bent portion.
In order to facilitate the work of attaching the terminal block, a convex portion is provided on the terminal block. Since this convex part exists in the lower surface of a terminal block, when attaching a terminal block to a bending part, this convex part cannot be visually recognized directly. For this reason, it may be difficult to engage this convex part with an engaging part. Then, a situation occurs in which the work before the terminal block is screwed, that is, it takes time to arrange the terminal block at a predetermined position.

そこで、上記構成では、端子台の側面下端部に当接するガイドを折曲部に設けている。これによって、端子台の位置がある程度定まるため、端子台を所定の位置に短時間で配置することができるようになり、端子台の取付作業の効率が上がる。   Therefore, in the above configuration, the bent portion is provided with a guide that contacts the lower end of the side surface of the terminal block. As a result, the position of the terminal block is determined to some extent, so that the terminal block can be placed at a predetermined position in a short time, and the efficiency of the terminal block mounting operation is increased.

上記空気調和機の室外機において、前記折曲部から前記室外機ケーシングの側板にわたるように、かつ前記折曲部と前記側板との間の折り目に対して交差するように溝が設けられていることが好ましい。   In the outdoor unit of the air conditioner, a groove is provided so as to extend from the bent portion to a side plate of the outdoor unit casing and to intersect with a fold between the bent portion and the side plate. It is preferable.

折曲部は、室外機ケーシング内への折り曲げにより構成されている。
端子台のねじ止めの際、端子台が折曲部に押し付けられる。このとき、折曲部には、この折曲部がさらに室外機ケーシング内へと傾くように力が加わる。このため、この押し付けの力が大きすぎると、折曲部が折曲がってしまうおそれがある。折曲部が所定の角度から更に折曲がると、端子台が室外機ケーシング内に配置された電装品と接触してショート等が生じるおそれがある。
The bent portion is configured by bending into the outdoor unit casing.
When the terminal block is screwed, the terminal block is pressed against the bent portion. At this time, a force is applied to the bent portion so that the bent portion is further inclined into the outdoor unit casing. For this reason, when this pressing force is too large, the bent portion may be bent. If the bent portion is further bent from a predetermined angle, the terminal block may come into contact with an electrical component arranged in the outdoor unit casing, thereby causing a short circuit or the like.

そこで、折曲部から側板にわたるように、かつその折り目に交差するように溝を設ける。この溝により、折り目の部分が補強され、折曲部が折れ曲がりにくくなる。このため、折曲部に力が加わっても、折曲部が折れ曲がることが抑制される。   Therefore, a groove is provided so as to extend from the bent portion to the side plate and intersect the fold. By this groove, the fold portion is reinforced and the bent portion is less likely to be bent. For this reason, even if force is added to a bending part, it is suppressed that a bending part bends.

上記空気調和機の室外機において、前記折曲部は、前記側板に繋がる基部と、この基部から上方向に延びる延長部とを有し、前記基部の下辺で折曲がり、かつ前記基部の両側端部それぞれで前記側板に繋がることが好ましい。   In the outdoor unit of the air conditioner, the bent portion includes a base portion connected to the side plate and an extension portion extending upward from the base portion, bends at a lower side of the base portion, and both side ends of the base portion. It is preferable that each part is connected to the side plate.

この構成は、折曲部が所定の角度から更に折れ曲がることを抑制するための他の手段である。
折曲部が室外機ケーシング内へと傾くようにこの折曲部に力が加わるとき、折曲部と側板との間の折り目を起点として折れ曲がる可能性が高い。これは、この部分に力が集中するためである。そこで、折曲部を、延長部と基部とを有するものとして、基部の下辺で折曲がるようにし、かつ基部の両端部それぞれで側板に繋がるようにしている。これにより、折曲部に加えられる力が折り目だけに集中するのではなく、その力が折り目を含めてその周辺に力が分散するようにしている。これにより、折曲部が折れ曲がることが抑制される。
This configuration is another means for suppressing the bent portion from further bending from a predetermined angle.
When a force is applied to the bent portion so that the bent portion is inclined into the outdoor unit casing, there is a high possibility that the bent portion will be bent starting from the fold between the bent portion and the side plate. This is because power concentrates on this part. Therefore, the bent portion is assumed to have an extension portion and a base portion, and is bent at the lower side of the base portion and connected to the side plate at both ends of the base portion. Thus, the force applied to the bent portion is not concentrated only on the fold, but the force is distributed to the periphery including the fold. Thereby, it is suppressed that a bending part bends.

上記空気調和機の室外機によれば、端子台を容易に取り付けることができる。   According to the outdoor unit of the air conditioner, the terminal block can be easily attached.

図1は、室外機1の斜視図である。図2は、図1の矢印A方向からみた、前板33を外した状態の室外機1の正面図である。なお、室外機1の前板33側を正面として室外機1を見たときに、左手側を室外機1の「左側」とし、右手側を室外機1の「右側」とする。
With reference to FIG.1 and FIG.2, an example of the outdoor unit 1 of an air conditioner is demonstrated.
FIG. 1 is a perspective view of the outdoor unit 1. FIG. 2 is a front view of the outdoor unit 1 with the front plate 33 removed, as seen from the direction of arrow A in FIG. When viewing the outdoor unit 1 with the front plate 33 side of the outdoor unit 1 as the front, the left hand side is the “left side” of the outdoor unit 1 and the right hand side is the “right side” of the outdoor unit 1.

室外機1は、室外機ケーシング3と、この室外機ケーシング3に収容される各種機器2と、信号配線及び電源配線の少なくとも一方が接続される端子台4とを備えている。信号配線は、室内機と情報通信するための配線であり、電源配線は電力供給用の配線である。   The outdoor unit 1 includes an outdoor unit casing 3, various devices 2 accommodated in the outdoor unit casing 3, and a terminal block 4 to which at least one of signal wiring and power supply wiring is connected. The signal wiring is wiring for information communication with the indoor unit, and the power wiring is power supply wiring.

室外機1は、室外機ケーシング3に収容される各種機器2として、少なくとも、熱交換器21、この熱交換器21の前に配置されるファン22と、圧縮機23と、これら装置を制御する制御装置24とを備える。   The outdoor unit 1 controls at least a heat exchanger 21, a fan 22 disposed in front of the heat exchanger 21, a compressor 23, and these devices as various devices 2 accommodated in the outdoor unit casing 3. And a control device 24.

制御装置24には端子台4が接続されている。端子台4は、制御装置24と外部装置との接続を中継する装置である。すなわち、端子台4は、制御装置24から引き出される配線と、外部装置から引き出される配線とを互いに接続する。   A terminal block 4 is connected to the control device 24. The terminal block 4 is a device that relays connection between the control device 24 and an external device. That is, the terminal block 4 connects the wiring drawn from the control device 24 and the wiring drawn from the external device to each other.

制御装置24は、圧縮機23のモータを駆動するための駆動回路と、駆動回路を冷却するヒートシンク26とを有する。この制御装置24は、冷却のためファン22の近くに配置される。制御装置24は、このように室外機1の奥に配置されるため、端子台4のような中継器がなければ、制御装置24と外部装置との接続が困難になる。このような理由から、中継器としての端子台4が室外機ケーシング3の近くに配置される。端子台4と制御装置24とは接続配線25で互いに接続されている。以下、室外機ケーシング3における端子台4の取付け構造について説明する。   The control device 24 includes a drive circuit for driving the motor of the compressor 23 and a heat sink 26 for cooling the drive circuit. The control device 24 is disposed near the fan 22 for cooling. Since the control device 24 is arranged in the back of the outdoor unit 1 in this way, it is difficult to connect the control device 24 and an external device without a repeater such as the terminal block 4. For this reason, the terminal block 4 as a repeater is disposed near the outdoor unit casing 3. The terminal block 4 and the control device 24 are connected to each other by a connection wiring 25. Hereinafter, the attachment structure of the terminal block 4 in the outdoor unit casing 3 will be described.

室外機ケーシング3は次の構成を有する。
室外機ケーシング3は、底板31と、天板32と、前板33と、側板35と、カバー36とを備える。室外機ケーシング3の内部空間は、仕切板37によって、熱交換器21及びファン22が配置される熱交換室3Aと、圧縮機23及び制御装置24が配置される機械室3Bとに仕切られている。
The outdoor unit casing 3 has the following configuration.
The outdoor unit casing 3 includes a bottom plate 31, a top plate 32, a front plate 33, a side plate 35, and a cover 36. The internal space of the outdoor unit casing 3 is partitioned by a partition plate 37 into a heat exchange chamber 3A in which the heat exchanger 21 and the fan 22 are arranged, and a machine room 3B in which the compressor 23 and the control device 24 are arranged. Yes.

前板33は、室外機ケーシング3の内部空間の前側及び左側を覆う。側板35は、機械室3Bの右側(機械室3Bにおいて仕切板37が配置される面とは反対側の面)を覆う。カバー36は、側板35に取り付けられるものであり、第1及び第2開口部38,39(後述)を覆う。   The front plate 33 covers the front side and the left side of the internal space of the outdoor unit casing 3. The side plate 35 covers the right side of the machine room 3B (the surface opposite to the surface on which the partition plate 37 is disposed in the machine room 3B). The cover 36 is attached to the side plate 35 and covers the first and second openings 38 and 39 (described later).

側板35には、第1及び第2開口部38,39が設けられている。
第1開口部38は、側板35の下部の一部切欠きにより構成されている。第1開口部38は、連絡冷媒配管を接続する冷媒配管を露出させる開口部であり、この第1開口部38を通じて、室外機1の冷媒配管と連絡配管とが接続される。
The side plate 35 is provided with first and second openings 38 and 39.
The first opening 38 is formed by a partial cutout in the lower part of the side plate 35. The first opening 38 is an opening that exposes the refrigerant pipe that connects the communication refrigerant pipe, and the refrigerant pipe and the communication pipe of the outdoor unit 1 are connected through the first opening 38.

第2開口部39は、側板35の上端から少し下がったところに設けられている。第2開口部39には、端子台4が取り付けられる折曲部5が設けられている。信号配線及び電源配線は、この第2開口部39を通じて端子台4に接続される。   The second opening 39 is provided at a position slightly lowered from the upper end of the side plate 35. The second opening 39 is provided with a bent portion 5 to which the terminal block 4 is attached. The signal wiring and the power supply wiring are connected to the terminal block 4 through the second opening 39.

図3及び図4を参照して、折曲部5の構造について説明する。
図3は、側板35を図1の矢印B方向から見た第2開口部39の正面図であり、図4は、側板35の第2開口部39の斜視図である。
With reference to FIG.3 and FIG.4, the structure of the bending part 5 is demonstrated.
3 is a front view of the second opening 39 when the side plate 35 is viewed from the direction of the arrow B in FIG. 1, and FIG. 4 is a perspective view of the second opening 39 of the side plate 35.

第2開口部39は、突出部(折曲部5の延長部52に対応する部分)が残るように側板35から所定形状の切除片61を切り取り、残った突出部を折り曲げることにより、形成される。   The second opening 39 is formed by cutting a cut piece 61 having a predetermined shape from the side plate 35 so that a protruding portion (a portion corresponding to the extension portion 52 of the bent portion 5) remains, and bending the remaining protruding portion. The

切除片61は、側板35の幅方向に延びる胴部62と、この胴部62の両側から下方向に延びる垂下部63とを有する。つまり、切除片61の形状は、馬蹄形または逆U字形に類似する。   The cut piece 61 includes a body portion 62 that extends in the width direction of the side plate 35, and a hanging portion 63 that extends downward from both sides of the body portion 62. That is, the shape of the cut piece 61 is similar to a horseshoe shape or an inverted U shape.

折曲部5は、側板35から切除片61を除去したことにより構成される突出部(延長部52に対応する部分)とこの突出部の根本部分(基部51)とを含む部分を室外機ケーシング3内に向けて折り曲げることにより構成される。すなわち、折曲部5は、側板35に繋がる基部51と、基部51から延長する延長部52とを有する。   The bent portion 5 includes a portion including a protruding portion (a portion corresponding to the extension portion 52) configured by removing the cut piece 61 from the side plate 35 and a base portion (base portion 51) of the protruding portion. 3 is formed by bending inward. In other words, the bent portion 5 includes a base portion 51 connected to the side plate 35 and an extension portion 52 extending from the base portion 51.

基部51は、下辺51B及び両側端部51Eそれぞれで側板35に繋がっている。下辺51Bが折曲部5の折り目57に対応する。両側端部51Eは、側板35における対応箇所をプレス変形させることにより構成されるものであり、曲面を呈する。   The base 51 is connected to the side plate 35 at each of the lower side 51B and both side ends 51E. The lower side 51 </ b> B corresponds to the fold 57 of the bent portion 5. Both end portions 51E are configured by press-deforming corresponding portions in the side plate 35, and exhibit curved surfaces.

延長部52は、側板35から切除片61を切り取ることにより第2開口部39に形成された突出部に対応する部分であり、基部51から上方向(設置された室外機1における上方向)にかつ室外機ケーシング3内に向かって延びる。延長部52の縦方向(室外機1の上下方向に対応する方向)の長さは、第2開口部39の縦方向の長さよりも短く、かつ延長部52の横幅は、第2開口部39の横幅よりも短い。   The extension portion 52 is a portion corresponding to the protruding portion formed in the second opening 39 by cutting the cut piece 61 from the side plate 35, and upward from the base 51 (upward in the installed outdoor unit 1). And it extends toward the inside of the outdoor unit casing 3. The length of the extension 52 in the vertical direction (the direction corresponding to the vertical direction of the outdoor unit 1) is shorter than the length of the second opening 39 in the vertical direction, and the width of the extension 52 is the second opening 39. Shorter than the width of

折曲部5には、この部分を補強する溝56が設けられている。
具体的には、折曲部5から側板35にわたるように、かつ折曲部5と側板35との間の折り目57に対して交差するように溝56が設けられている。この溝56は、折曲部5及び側板35の外面が凹みかつ内面が突出するように、構成されている。
The bent portion 5 is provided with a groove 56 that reinforces this portion.
Specifically, a groove 56 is provided so as to extend from the bent portion 5 to the side plate 35 and to intersect with the crease 57 between the bent portion 5 and the side plate 35. The groove 56 is configured such that the outer surfaces of the bent portion 5 and the side plate 35 are recessed and the inner surface protrudes.

溝56の断面は、図3では、略U字であるが、この溝56は、バスタブ形状やV字形であってもよい。また、この溝56は、図3に示すように、折り目57に対して直交することが好ましい。   The cross section of the groove 56 is substantially U-shaped in FIG. 3, but the groove 56 may be bathtub-shaped or V-shaped. The groove 56 is preferably orthogonal to the crease 57 as shown in FIG.

溝56は、折曲部5から側板35にわたるように、1本、好ましくは複数本設けられる。溝56の本数は、延長部52の幅によって適宜設定される。図3に示す例では、溝56を2本設けている。溝56の長さは、特に制限されないが、折曲部5に設けられるねじ孔53や係合部54(後述)の形成において互いに干渉し合わないように設定される。このような溝56は、所謂ビード加工により形成される。   One, preferably a plurality of grooves 56 are provided so as to extend from the bent portion 5 to the side plate 35. The number of the grooves 56 is appropriately set according to the width of the extension portion 52. In the example shown in FIG. 3, two grooves 56 are provided. The length of the groove 56 is not particularly limited, but is set so as not to interfere with each other in forming a screw hole 53 and an engaging portion 54 (described later) provided in the bent portion 5. Such a groove 56 is formed by so-called bead processing.

また、折曲部5には、端子台4を固定するためのねじ孔53と、端子台4の凸部45(図5参照)と係合する係合部54とが設けられている。
折曲部5において、ねじ孔53は、端子台4の貫通孔46(図5参照)に対応する位置に形成されている。係合部54は端子台4の凸部45に対応する位置に設けられている。
Further, the bent portion 5 is provided with a screw hole 53 for fixing the terminal block 4 and an engaging portion 54 that engages with the convex portion 45 (see FIG. 5) of the terminal block 4.
In the bent portion 5, the screw hole 53 is formed at a position corresponding to the through hole 46 (see FIG. 5) of the terminal block 4. The engaging portion 54 is provided at a position corresponding to the convex portion 45 of the terminal block 4.

係合部54は、端子台4の凸部45が入る形状に構成される。例えば、凸部45が円形である場合は、係合部54は、円形または楕円形の貫通孔または凹部として構成される。なお、係合部54の大きさは、凸部45が入り込む寸法であればよい。すなわち、係合部54の大きさは、凸部45が嵌り込む大きさに設定してもよいし、また、凸部45が入り込み易いように凸部45の寸法よりも大きくしてもよい。   The engaging portion 54 is configured to have a shape into which the convex portion 45 of the terminal block 4 is inserted. For example, when the convex portion 45 is circular, the engaging portion 54 is configured as a circular or elliptical through hole or concave portion. In addition, the magnitude | size of the engaging part 54 should just be a dimension in which the convex part 45 enters. That is, the size of the engaging portion 54 may be set to a size in which the convex portion 45 fits, or may be larger than the size of the convex portion 45 so that the convex portion 45 can easily enter.

また、折曲部5には、端子台4の側面下端部44B(図5参照)に当接するガイド55が少なくとも1つ設けられていることが好ましい。
ガイド55は、端子台4を折曲部5に取り付けるときに、この端子台4を折曲部5に対して所定の位置に案内するものである。また、ガイド55は、端子台4をねじ止めする際の端子台4の回転を抑制するものでもある。
Further, it is preferable that the bent portion 5 is provided with at least one guide 55 that comes into contact with the side surface lower end portion 44 </ b> B (see FIG. 5) of the terminal block 4.
The guide 55 guides the terminal block 4 to a predetermined position with respect to the bent portion 5 when the terminal block 4 is attached to the bent portion 5. Further, the guide 55 also suppresses rotation of the terminal block 4 when the terminal block 4 is screwed.

図4に示すように、このガイド55は、折曲部5に端子台4が取り付けられたときに、端子台4の側面下端部44Bが位置する部分に沿うように、かつ折曲部5の外面から突出するように設けられる。ガイド55の本数は1本でもよいが、図4に示すように端子台4の両側面44それぞれに対してガイド55が設けられることがより好ましい。   As shown in FIG. 4, when the terminal block 4 is attached to the bent portion 5, the guide 55 extends along the portion where the side surface lower end portion 44 B of the terminal block 4 is located and the bent portion 5. It is provided so as to protrude from the outer surface. The number of guides 55 may be one, but as shown in FIG. 4, it is more preferable that the guides 55 are provided for both side surfaces 44 of the terminal block 4.

図5を参照して、端子台4の構造を説明する。
端子台4は、基台40と、信号配線、電源配線等の外部装置との接続に用いられる配線が接続される接続部41とを有する。各接続部41は隔壁42により仕切られている。基台40の中央部には、ねじが挿通する貫通孔46が設けられている。
The structure of the terminal block 4 will be described with reference to FIG.
The terminal block 4 includes a base 40 and a connection portion 41 to which wiring used for connection to an external device such as signal wiring and power wiring is connected. Each connecting portion 41 is partitioned by a partition wall 42. A through hole 46 through which a screw is inserted is provided at the center of the base 40.

端子台4の下面43(基台40の下面に対応する。)には、この面から突出する凸部45が設けられている。凸部45は、端子台4を位置決めするものである。例えば、凸部45と基台40とは、成形上において一体のものとして構成される。端子台4の側面44(基台40の側面に対応する。)は平坦に構成されている。   On the lower surface 43 of the terminal block 4 (corresponding to the lower surface of the base 40), a convex portion 45 protruding from this surface is provided. The convex part 45 positions the terminal block 4. For example, the convex part 45 and the base 40 are configured as an integral part in molding. The side surface 44 (corresponding to the side surface of the base 40) of the terminal block 4 is configured to be flat.

図6に、端子台4が取り付けられた側板35を示す。
端子台4は、凸部45が折曲部5の係合部54に係合した状態で、基台40の貫通孔46と折曲部5のねじ孔53との連通孔にねじをねじ込むことにより、取り付けられている。また、端子台4の側面下端部44Bはガイド55に当接している。
FIG. 6 shows the side plate 35 to which the terminal block 4 is attached.
In the terminal block 4, the screw 45 is screwed into the communication hole between the through hole 46 of the base 40 and the screw hole 53 of the bent portion 5 with the convex portion 45 engaged with the engaging portion 54 of the bent portion 5. It is attached by. Further, the side surface lower end 44 </ b> B of the terminal block 4 is in contact with the guide 55.

The effect | action is demonstrated about the attachment structure of such a terminal block 4. FIG.
When the terminal block 4 is attached, the side surface lower end 44 </ b> B of the terminal block 4 is brought into contact with the guide 55, and the terminal block 4 is disposed between the two guides 55. Then, the terminal block 4 is moved along the extending direction of the guide 55, and the terminal block 4 is arranged at a position where the convex portion 45 of the lower surface 43 engages with the engaging portion 54 of the bent portion 5. In this state, that is, in a state where the convex portion 45 of the lower surface 43 is engaged with the engaging portion 54 of the bent portion 5, the terminal block 4 is screwed. When screwing, the terminal block 4 is rotated by torque, but the rotation of the terminal block 4 is suppressed by the engagement of the convex portion 45 and the engaging portion 54, so that screwing is completed in a short time without unnecessary effort. To do.

以下、本実施形態の効果を説明する。
(1)室外機ケーシング3の側板35は、内側への折り曲げにより構成された折曲部5を有する。折曲部5には、端子台4の貫通孔46に対応するねじ孔53と、端子台4の下面43に設けられた凸部45が係合する係合部54とが設けられている。そして、端子台4は、凸部45が折曲部5の係合部54に係合し、かつ貫通孔46とねじ孔53との連通孔にねじがねじ入れられることにより、折曲部5に取り付けられている。
Hereinafter, the effect of this embodiment will be described.
(1) The side plate 35 of the outdoor unit casing 3 has a bent portion 5 formed by bending inward. The bent portion 5 is provided with a screw hole 53 corresponding to the through hole 46 of the terminal block 4 and an engaging portion 54 with which the convex portion 45 provided on the lower surface 43 of the terminal block 4 is engaged. The terminal block 4 has the convex portion 45 engaged with the engaging portion 54 of the bent portion 5, and a screw is screwed into the communication hole between the through hole 46 and the screw hole 53. Is attached.

端子台4を折曲部5に取り付けるとき、折曲部5のねじ孔53と端子台4の貫通孔46との連通孔にねじがねじ入れられることにより、端子台4が折曲部5に取り付けられる。この取付けの際、端子台4の凸部45を係合部54に係合させることができるため、端子台4の回転が抑制される。これにより、端子台4を容易に取り付けることができる。   When the terminal block 4 is attached to the bent portion 5, a screw is screwed into the communication hole between the screw hole 53 of the bent portion 5 and the through hole 46 of the terminal block 4, so that the terminal block 4 is moved to the bent portion 5. It is attached. At the time of this attachment, since the convex part 45 of the terminal block 4 can be engaged with the engaging part 54, rotation of the terminal block 4 is suppressed. Thereby, the terminal block 4 can be attached easily.

(2)上記構成の空気調和機の室外機1において、折曲部5には、端子台4の側面下端部44Bに当接するガイド55が少なくとも1つ設けられていることが好ましい。
端子台4の取付け作業を容易とするために端子台4に凸部45を設けている。凸部45は端子台4の下面43にあるため端子台4を折曲部5に取り付けるときは、この凸部45を直接視認することができない。このため、この凸部45を係合部54に係合しにくい場合がある。そうすると、端子台4をねじ止めする前段階の作業、すなわち端子台4を所定の位置に配置することに時間を要するといった事態が生じる。
(2) In the outdoor unit 1 of the air conditioner having the above-described configuration, it is preferable that the bent portion 5 is provided with at least one guide 55 that contacts the side surface lower end portion 44B of the terminal block 4.
In order to facilitate the mounting work of the terminal block 4, a convex portion 45 is provided on the terminal block 4. Since the convex portion 45 is on the lower surface 43 of the terminal block 4, when the terminal block 4 is attached to the bent portion 5, the convex portion 45 cannot be directly visually recognized. For this reason, it may be difficult to engage the convex portion 45 with the engaging portion 54. If it does so, the operation | work of the step before screwing the terminal block 4, ie, the situation where it takes time to arrange the terminal block 4 in a predetermined position will arise.

そこで、上記構成では、端子台4の側面下端部44Bに当接するガイド55を折曲部5に設けている。これによって、端子台4の位置がある程度定まるため、端子台4を所定の位置に短時間で配置することができるようになり、端子台4の取付作業の効率が上がる。   Therefore, in the above configuration, the bent portion 5 is provided with a guide 55 that contacts the side surface lower end portion 44B of the terminal block 4. Thereby, since the position of the terminal block 4 is determined to some extent, the terminal block 4 can be arranged at a predetermined position in a short time, and the efficiency of the work of attaching the terminal block 4 is increased.

(3)上記空気調和機の室外機1において、折曲部5から室外機ケーシング3の側板35にわたるように、かつ折曲部5と側板35との間の折り目57に対して交差するように溝56が設けられていることが好ましい。   (3) In the outdoor unit 1 of the air conditioner, it extends from the bent portion 5 to the side plate 35 of the outdoor unit casing 3 and intersects the fold 57 between the bent portion 5 and the side plate 35. A groove 56 is preferably provided.

折曲部5は、室外機ケーシング3内への折り曲げにより構成されている。
端子台4のねじ止めの際、端子台4が折曲部5に押し付けられる。このとき、折曲部5には、この折曲部5がさらに室外機ケーシング3内へと傾くように力が加わる。このため、この押し付けの力が大きすぎると、折曲部5が折曲がってしまうおそれがある。折曲部5が所定の角度から更に折曲がると、端子台4が室外機ケーシング3内に配置された電装品(例えば、制御装置24)と接触してショート等が生じるおそれがある。
The bent portion 5 is configured by bending into the outdoor unit casing 3.
When the terminal block 4 is screwed, the terminal block 4 is pressed against the bent portion 5. At this time, a force is applied to the bent portion 5 so that the bent portion 5 is further inclined into the outdoor unit casing 3. For this reason, if the pressing force is too large, the bent portion 5 may be bent. If the bent portion 5 is further bent from a predetermined angle, the terminal block 4 may come into contact with an electrical component (for example, the control device 24) disposed in the outdoor unit casing 3 to cause a short circuit or the like.

そこで、折曲部5から側板35にわたるように、かつその折り目57に交差するように溝56を設ける。この溝56により、折り目57の部分が補強され、折曲部5が折れ曲がりにくくなる。このため、折曲部5に力が加わっても、折曲部5が折れ曲がることが抑制される。   Therefore, a groove 56 is provided so as to extend from the bent portion 5 to the side plate 35 and to intersect the fold 57. The groove 56 reinforces the portion of the fold 57 and makes the bent portion 5 difficult to bend. For this reason, even if force is added to the bending part 5, it is suppressed that the bending part 5 bends.

(4)上記空気調和機の室外機1において、折曲部5は、側板35に繋がる基部51と、この基部51から上方向に延びる延長部52とを有し、基部51の下辺51Bで折曲がり、かつ基部51の両側端部51Eそれぞれで側板35に繋がることが好ましい。   (4) In the outdoor unit 1 of the air conditioner, the bent portion 5 includes a base portion 51 connected to the side plate 35 and an extension portion 52 extending upward from the base portion 51, and is folded at a lower side 51 </ b> B of the base portion 51. It is preferable to bend and connect to the side plate 35 at both end portions 51E of the base portion 51.

この構成は、折曲部5が所定の角度から更に折れ曲がることを抑制するための他の手段である。
折曲部5が室外機ケーシング3内へと傾くようにこの折曲部5に力が加わるとき、折曲部5と側板35との間の折り目57を起点として折れ曲がる可能性が高い。これは、この部分に力が集中するためである。そこで、折曲部5を、延長部52と基部51とを有するものとして、基部51の下辺51Bで折曲がるようにし、かつ基部51の両側端部51Eそれぞれで側板35に繋がるようにしている。これにより、折曲部5に加えられる力が折り目57だけに集中するのではなく、その力が折り目57を含めてその周辺に力が分散するようにしている。これにより、折曲部5が折れ曲がることが抑制される。
This configuration is another means for suppressing the bent portion 5 from further bending from a predetermined angle.
When a force is applied to the bent portion 5 so that the bent portion 5 is inclined into the outdoor unit casing 3, there is a high possibility that the bent portion 5 will be bent starting from the fold 57 between the bent portion 5 and the side plate 35. This is because power concentrates on this part. Therefore, the bent portion 5 is assumed to have an extension portion 52 and a base portion 51, and is bent at the lower side 51B of the base portion 51, and is connected to the side plate 35 at both side end portions 51E of the base portion 51. Thus, the force applied to the bent portion 5 is not concentrated only on the fold 57 but the force is distributed to the periphery including the fold 57. Thereby, it is suppressed that the bending part 5 bends.

(Other embodiments)
Note that the embodiment is not limited to the above-described embodiment, and the embodiment may be modified as shown below, for example.

・上記実施形態では、折曲部5に端子台4を案内するガイド55を設けている。このガイド55は、折曲部5の表面から突出するように設けられているが、ガイド55を次のように構成してもよい。例えば、折曲部5の側端を折り曲げて屈曲部を構成し、この屈曲部を端子台4の側面下端部44Bに当接させるものとして、ガイド55を構成する。このようにして構成されたガイド55は、端子台4を所定位置に案内する機能と、端子台4の回転を抑制する機能とを有する。   In the above embodiment, the bent portion 5 is provided with the guide 55 that guides the terminal block 4. The guide 55 is provided so as to protrude from the surface of the bent portion 5, but the guide 55 may be configured as follows. For example, the guide 55 is configured such that a bent portion is formed by bending a side end of the bent portion 5 and the bent portion is brought into contact with the lower end portion 44B of the side surface of the terminal block 4. The guide 55 configured as described above has a function of guiding the terminal block 4 to a predetermined position and a function of suppressing the rotation of the terminal block 4.
