(7) Modified Example 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 the terminal block provided on the casing 71. Although the structure is supported by the support member 87, the terminal block 186 is supported by the terminal block support member 187 provided on the housing 171 as in the electrical component assembly 107 of the present modification shown in FIGS. It may be a structured. Below, the electrical component assembly 107 of this modification is demonstrated. It should be noted that each part of the electrical component assembly 107 excluding the terminal block 186, the terminal block support member 187, and part of the housing 171 (specifically, the positioning portions 188 and 189) is the same as that of the electrical component assembly 7 of the above-described embodiment. Since it is the same as each part, description is abbreviate | omitted here.

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 of the above-described embodiment, and one end of the terminal block fixing plate 186b on the partition plate 28 side is the front of the partition plate 28 or the left front plate 23. Not fixed to.

  Next, like the terminal block support member 87 of the electrical component assembly 7 of the above-described embodiment, the terminal block support member 187 supports the terminal block 186 when the electrical component assembly 107 is provided in the machine room S2. The terminal block support 187a and the electrical component assembly 107 can be rotated around the engagement shaft 171a (the shaft center is O) 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. It is a rod-shaped member which has the frame supported part 187b supported by. The terminal block support member 187 can move the first terminal block support portion 187a toward 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 center of the shaft 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. The terminal block 186 is such that the terminal block support member 187 is inclined with respect to the board surface of the control board 91 by an angle β, and the terminal block fixing plate 186b is only angle γ with respect to the terminal block support member 187. By being inclined, the unit casing 2 is arranged so as to face the front surface (hereinafter, this state is referred to as a first state). Moreover, 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 first state described above. More specifically, a claw portion 186d formed at one end of the terminal block fixing plate 186b is engaged with a notch 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.

  As described above, in the electrical component assembly 107 according to this modification, the terminal block 86 integrated with the casing 171 is disposed so as to face the front surface of the unit casing 2 via the terminal block support member 187 provided in the casing 171. The terminal block support member 187 and the notch 171b formed in the housing 171 are supported.

  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.

  As described above, when the terminal block supported portion 187b of the terminal block support member 187 and the terminal block supported portion 186c of the terminal block fixing plate 186b are turned to the first state, the terminal block 86 is moved to the front surface of the unit casing 2. However, the terminal block 186 and the terminal block support member 187 are disposed on the outside of the housing 171 in plan view of the unit casing 2 (specifically, from the outer surface of the board protection plate 76) by that amount. It will protrude. For this reason, in this state, the package shape when the electrical component assembly 107 is transported alone becomes large, and the electrical component assembly 107 cannot be transported efficiently.

  Therefore, in the electrical component assembly 107 according to the present embodiment, the inclination of the terminal block support member 187 with respect to the substrate surface of the casing 171 causes the angle β in the first state by rotating the casing supported portion 187b of the terminal block support member 187. The substrate surface of the housing 171 is rotated more slowly (here, inclined by an angle δ with respect to the substrate surface of the housing 171) and the terminal block supported portion 186c of the terminal block fixing plate 186b is rotated. The terminal block support member 187 can be switched to the second state where the inclination of the terminal block support member 187 is less than the angle γ in the first state (here, inclined by the angle ε with respect to the terminal block support member). Yes. Moreover, the other end of the terminal block fixing plate 186b (here, the end portion 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 186 b is engaged with a claw portion 171 c as a second positioning portion formed on the housing 171. The claw portion 171c has the other end of the terminal block fixing plate 186b along the protective plate portion 77 of the housing 171 like the locking claw 77g formed on the housing 71 of the electrical component assembly 7 of the above-described embodiment. This is the part that can be mounted. 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. When the terminal block support member 187 and the terminal block fixing plate 186b are switched to the second state, the terminal block 186 is disposed along the outer surface of the casing 171 in the plan view of the unit casing 2, so that the terminal block 186 is the casing 171. It is possible to prevent the electric component assembly 107 from being protruded as much as possible from the outer surface of the electric component assembly.

  As described above, in the electrical component assembly 107 according to the present modification, the terminal block support member 187 and the terminal block fixing plate 186b can be accommodated in the housing 171 by simply switching the terminal block support member 187 and the terminal block fixing plate 186b without removing the terminal block 186. It is like that.
