Here, the first terminal block support portion 87a of the terminal block support member 87 is removed. The terminal block engaging claw 87c is formed, and this terminal block engaging claw 87c is a mounting structure that is fitted into the engaging hole 86c formed at the other end of the terminal block fixing plate 86b of the terminal block 86. Therefore, the terminal block 86 can be easily removed from the first terminal block support portion 87a by elastically deforming the terminal block engaging claws 87c. Conversely, when the terminal block 86 is attached to the first terminal block support 87a, the terminal block engaging claw 87c is elastically deformed so that it can be easily fitted into the engaging hole 86c. .
[0027] さらに、端子台サポート部材 87から端子台 86を取り外して端子台サポート部材 87 を第 2状態に切り換えた後には、端子台 86を躯体 71に着脱自在に装着することがで きるようになつている。具体的には、躯体 71を構成する基板保護プレート 76の保護 プレート部 77 (ここでは、後側保護プレート部 77b)の外面に形成された複数 (ここで は  [0027] Further, after the terminal block 86 is removed from the terminal block support member 87 and the terminal block support member 87 is switched to the second state, the terminal block 86 can be detachably attached to the housing 71.

[0031] (7)変形例  [0031] (7) Modification
上述の実施形態の電装品アセンブリ 7では、端子台 86がユニットケーシング 2又は 仕切板 28にユニットケーシング 2の前面を向くように固定されるとともに、躯体 71に設 けられた端子台サポート部材 87によって支持された構造であった力 図 9及び図 10 に示される本変形例の電装品アセンブリ 107のように、端子台 186が躯体 171に設 けられた端子台サポート部材 187によって支持された構造であってもよい。以下に、 本変形例の電装品アセンブリ 107について説明する。尚、電装品アセンブリ 107のう ち端子台 186、端子台サポート部材 187及び躯体 171の一部（具体的には、位置決 め部 188、 189)を除く各部は、上述の実施形態の電装品アセンブリ 7の各部と同様 であるため、ここでは説明を省略する。  In the electrical component assembly 7 of the above-described embodiment, the terminal block 86 is fixed to the unit casing 2 or the partition plate 28 so as to face the front surface of the unit casing 2, and by the terminal block support member 87 provided on the casing 71. Force that was supported structure Like the electrical component assembly 107 of this modification shown in FIGS. 9 and 10, the terminal block 186 is supported by the terminal block support member 187 provided on the housing 171. There may be. Hereinafter, the electrical component assembly 107 of this modification will be described. Of the electrical component assembly 107, each part except the terminal block 186, the terminal block support member 187, and a part of the housing 171 (specifically, the positioning portions 188 and 189) is the electrical component of the above-described embodiment. Since it is the same as each part of the assembly 7, the description is omitted here.
[0032] 端子台 186は、上述の実施形態の電装品アセンブリ 7の端子台 86と同様、主として 、電源接続用の複数の端子部を有する端子台本体 186aと、端子台本体 186aの背 面が固定される端子台固定プレート 186bとを有して 、る。電装品アセンブリ 107が 機械室 S2内に設けられた状態において、端子台 186は、上述の実施形態の電装品 アセンブリ 7の端子台 186と同様、端子台本体 186aの端子部がユニットケーシング 2 の前面を向くように配置されている。但し、本変形例の端子台 186は、上述の実施形 態の電装品アセンブリ 7の端子台とは異なり、端子台固定プレート 186bの仕切板 28 側の一端が仕切板 28や左前板 23の前部に固定されていない。 [0032] Similar to the terminal block 86 of the electrical component assembly 7 of the above-described embodiment, the terminal block 186 mainly includes a terminal block body 186a having a plurality of terminal portions for power connection, and the back of the terminal block body 186a. And a terminal block fixing plate 186b to which the surface is fixed. In a state where the electrical component assembly 107 is provided in the machine room S2, the terminal block 186 is similar to the terminal block 186 of the electrical component assembly 7 of the above-described embodiment, and the terminal portion of the terminal block body 186a is the front surface of the unit casing 2. It is arranged to face. However, the terminal block 186 of this modification is different from the terminal block of the electrical component assembly 7 in the embodiment described above, and one end of the terminal block fixing plate 186b on the partition plate 28 side is in front of the partition plate 28 and the left front plate 23. Not fixed to the part.
次に、端子台サポート部材 187は、上述の実施形態の電装品アセンブリ 7の端子台 サポート部材 87と同様、電装品アセンブリ 107が機械室 S2内に設けられた状態にお いて端子台 186を支持する第 1端子台支持部 187aと、電装品アセンブリ 107が機械 室 S 2内に設けられた状態にお!/ヽて躯体 171の上下方向に延びる軸である係合軸 1 71aまわり（軸中心を Oとする）に回動可能に支持される躯体被支持部 187bとを有す る棒状の部材である。端子台サポート部材 187は、躯体被支持部 187bを回動させる ことによって、第 1端子台支持部 187aを制御基板 91の基板面に対して接近又は離 反させることが可能である。また、第 1端子台支持部 187aには、電装品アセンブリ 10 7が機械室 S2内に設けられた状態において躯体 171の上下方向に延びる軸である 係合軸 187cまわり（軸中心を Pとする）が形成されており、この係合軸 187cに端子台 固定プレート 186bの背面に形成された端子台被支持部 186cが回動可能に支持さ れている。そして、端子台 186は、端子台サポート部材 187が制御基板 91の基板面 に対して角度 ι8だけ傾斜した状態にされ、さらに、端子台固定プレート 186bが端子 台サポート部材 187に対して角度 γだけ傾斜した状態にされることで、ユニットケー シング 2の前面を向くように配置されている（以下、この状態を第 1状態とする)。し力も 、端子台固定プレート 186bの一端 (ここでは、仕切板 28側の端部）は、上述の第 1状 態を保持したままで、躯体 171に支持されている。より具体的には、端子台固定プレ ート 186bの一端に形成された爪部 186dが躯体 171に形成された第 1位置決め部と しての切り欠き部 171bに係合している。すなわち、切り欠き部 171bは、端子台 186 及び端子台サポート部材 187を第 1状態に位置決めする機能を有している。  Next, the terminal block support member 187 supports the terminal block 186 in a state where the electrical component assembly 107 is provided in the machine room S2, similarly to the terminal block support member 87 of the electrical component assembly 7 of the above-described embodiment. The first terminal block support 187a and the electrical component assembly 107 are provided in the machine room S2. Is a rod-shaped member having a frame supported portion 187b that is rotatably supported by O). The terminal block support member 187 can move the first terminal block support portion 187a closer to or away from the substrate surface of the control board 91 by rotating the housing supported portion 187b. The first terminal block support portion 187a has an engagement shaft 187c that is an axis extending in the vertical direction of the housing 171 in a state where the electrical component assembly 107 is provided in the machine room S2 (the axis center is P). The terminal block supported portion 186c formed on the back surface of the terminal block fixing plate 186b is rotatably supported by the engagement shaft 187c. In the terminal block 186, the terminal block support member 187 is inclined with respect to the board surface of the control board 91 by an angle ι8, and the terminal block fixing plate 186b is inclined with respect to the terminal block support member 187 by an angle γ. By being inclined, it is arranged so as to face the front of the unit casing 2 (hereinafter, this state is referred to as a first state). In addition, one end of the terminal block fixing plate 186b (here, the end portion on the partition plate 28 side) is supported by the housing 171 while maintaining the above-described first state. More specifically, a claw portion 186d formed at one end of the terminal block fixing plate 186b is engaged with a cutout portion 171b as a first positioning portion formed in the housing 171. That is, the notch 171b has a function of positioning the terminal block 186 and the terminal block support member 187 in the first state.
このように、本変形例の電装品アセンブリ 107では、躯体 171に設けられた端子台 サポート部材 187を介して、躯体 171と一体の端子台 86がユニットケーシング 2の前 面を向くように配置されており、端子台サポート部材 187及び躯体 171に形成された 切り欠き部 171bによって支持されている。 As described above, in the electrical component assembly 107 according to this modification, the terminal block 86 integrated with the housing 171 is disposed in front of the unit casing 2 via the terminal block support member 187 provided in the housing 171. It is arranged so as to face the surface, and is supported by a notch 171b formed in the terminal block support member 187 and the casing 171.
本変形例の電装品アセンブリ 107では、上述の実施形態の電装品アセンブリ 7と同 様、端子台 186及び端子台サポート部材 187を躯体 171に収納することができるよう になっている。このような端子台 186及び端子台サポート部材 187の収納構造につ いて説明する。  In the electrical component assembly 107 of this modification, the terminal block 186 and the terminal block support member 187 can be accommodated in the housing 171 as in the electrical component assembly 7 of the above-described embodiment. The storage structure of the terminal block 186 and the terminal block support member 187 will be described.
上述のように、端子台サポート部材 187の躯体被支持部 187b及び端子台固定プ レート 186bの端子台被支持部 186cを回動させることで第 1状態にすると、端子台 8 6がユニットケーシング 2の前面を向くように配置される力 その分だけ、ユニットケー シング 2の平面視における躯体 171の外側に (具体的には、基板保護プレート 76の 外面力も）、端子台 186及び端子台サポート部材 187がはみ出すことになる。このた め、このままでは、電装品アセンブリ 107を単体で輸送する場合の荷姿が大きくなつ てしまい、電装品アセンブリ 107の輸送を効率的に行うことができない。  As described above, when the terminal block support 187b of the terminal block support member 187 and the terminal block support 186c of the terminal block fixing plate 186b are turned to the first state by rotating, the terminal block 86 is unit casing 2 The force placed so as to face the front of the terminal casing 186 and the terminal block support member on the outside of the housing 171 in plan view of the unit casing 2 (specifically, the external force of the board protection plate 76) 187 will protrude. For this reason, in this state, when the electric component assembly 107 is transported alone, the package form becomes large, and the electric component assembly 107 cannot be transported efficiently.
そこで、本実施形態の電装品アセンブリ 107では、端子台サポート部材 187の躯体 被支持部 187bを回動させることにより、躯体 171の基板面に対する端子台サポート 部材 187の傾斜が第 1状態における角度 βよりも緩い (ここでは、躯体 171の基板面 に対して角度 δだけ傾斜した)状態とし、かつ、端子台固定プレート 186bの端子台 被支持部 186cを回動させることにより、躯体 171の基板面に対する端子台サポート 部材 187の傾斜が第 1状態における角度 γよりも緩い (ここでは、端子台サポート部 材に対して角度 εだけ傾斜した)状態とした状態である第 2状態に切り換え可能にな つている。し力も、端子台固定プレート 186bの他端 (ここでは、反仕切板 28側の端部 )は、上述の第 2状態を保持したままで、躯体 171に支持されている。より具体的には 、端子台固定プレート 186bの他端が躯体 171に形成された第 2位置決め部としての 爪部 171cに係合している。この爪部 171cは、例えば、上述の実施形態の電装品ァ センブリ 7の躯体 71に形成された係止爪 77gのように、端子台固定プレート 186bの 他端を躯体 171の保護プレート部 77に沿うように装着することができる部分である。 すなわち、爪部 171cは、端子台 186及び端子台サポート部材 187を第 2状態に位 置決めする機能を有している。そして、端子台サポート部材 187及び端子台固定プ レート 186bを第 2状態に切り換えると、端子台 186がユニットケーシング 2の平面視 における躯体 171の外面に沿って配置されるため、端子台 186が躯体 171の外面か ら極力に突出しないようにすることができ、これにより、電装品アセンブリ 107の輸送 時の荷姿をさらにコンパクトにすることができる。 Therefore, in the electrical component assembly 107 of the present embodiment, the inclination of the terminal block support member 187 with respect to the board surface of the casing 171 is the angle β in the first state by rotating the casing supported portion 187b of the terminal block support member 187. By rotating the terminal block supported portion 186c of the terminal block fixing plate 186b by rotating the terminal block supported plate 186c of the terminal block fixing plate 186b, the substrate surface of the casing 171 is rotated. The terminal block support member 187 can be switched to the second state in which the inclination of the terminal block support member 187 is less than the angle γ in the first state (in this case, the terminal block support member is inclined by the angle ε). It is. Also, the other end of the terminal block fixing plate 186b (here, the end on the side opposite to the partition plate 28) is supported by the housing 171 while maintaining the second state described above. More specifically, the other end of the terminal block fixing plate 186b is engaged with a claw portion 171c as a second positioning portion formed on the housing 171. For example, the claw portion 171c is connected to the protective plate portion 77 of the housing 171 at the other end of the terminal block fixing plate 186b, like a locking claw 77g formed on the housing 71 of the electrical component assembly 7 of the above-described embodiment. It is a part that can be fitted along. That is, the claw portion 171c has a function of positioning the terminal block 186 and the terminal block support member 187 in the second state. Then, the terminal block support member 187 and the terminal block fixing block When the rate 186b is switched to the second state, the terminal block 186 is arranged along the outer surface of the housing 171 in plan view of the unit casing 2, so that the terminal block 186 does not protrude as much as possible from the outer surface of the housing 171. As a result, the packaging of the electrical component assembly 107 during transportation can be made more compact.
[0035] このように、本変形例の電装品アセンブリ 107では、端子台 186を取り外すことなく 、端子台サポート部材 187及び端子台固定プレート 186bを第 2状態に切り換えるだ けで、躯体 171に収容することができるようになつている。 As described above, in the electrical component assembly 107 according to this modification, the terminal block support member 187 and the terminal block fixing plate 186b are simply switched to the second state without removing the terminal block 186, and are accommodated in the housing 171. I am able to do that.

例えば、上述の実施形態においては、制御基板 91の基板面がユニットケーシング 2の前面に対して傾斜するように躯体 71が配置されている力 制御基板 91の基板面 がユニットケーシング 2の前面に対して傾斜するように躯体 71が直交するように配置 されていてもよい。  For example, in the above-described embodiment, the force in which the casing 71 is arranged so that the substrate surface of the control substrate 91 is inclined with respect to the front surface of the unit casing 2. The substrate surface of the control substrate 91 is against the front surface of the unit casing 2. The housing 71 may be arranged so as to be orthogonal to each other so as to be inclined.
