Next, theelectrical component box 70 disposed inside the casing 40 will be described in detail with reference to FIGS. A control board 62 on which various electronic components are mounted is attached to the electrical component box 70. The control board 62 controls the operation of each device such as the compressor 31, the electric expansion valve 32, and the outdoor fan 33.
次に、図10~図13を参照して、ケーシング40の内部に配置される電装品ボックス70について詳細に説明する。この電装品ボックス70には、各種の電子部品が実装された制御基板62が取り付けられる。この制御基板62は、圧縮機31、電動膨張弁32、室外ファン33などの各機器の動作を制御している。 [Electrical component box]
Next, the
電装品ボックス70は、樹脂製であって、一体成形によって構成されている。図10に示すように、電装品ボックス70の内部には、制御基板62を収容する基板収容部70aが設けられている。基板収容部70aは、天面部71と、底面部72と、右側面部73と、左側面部74とによって囲まれた領域であって、制御基板62は、電装品ボックス70内で立設した状態で配置される。この基板収容部70aには、基板収容部70aの深さ方向(X方向)に関して、制御基板62を所定の位置で支持する複数の支持リブ75が各所に設けられている。また、基板収容部70aには、制御基板62の切欠部(図示省略)に係合する爪部76が設けられている。この爪部76は、撓み変形可能であって、当該爪部76が切欠部(図示省略)に係合することによって制御基板62が固定される。上記した爪部76や基板収容部70aの各所に設けられる突起部77(図10参照)に対応する部分には、金型を抜くための金型用穴78が形成されている。
The electrical component box 70 is made of resin and is formed by integral molding. As shown in FIG. 10, a board housing portion 70 a that houses the control board 62 is provided inside the electrical component box 70. The substrate housing portion 70 a is an area surrounded by the top surface portion 71, the bottom surface portion 72, the right side surface portion 73, and the left side surface portion 74, and the control substrate 62 is erected in the electrical component box 70. Be placed. A plurality of support ribs 75 that support the control substrate 62 at predetermined positions are provided in the substrate accommodating portion 70a in the depth direction (X direction) of the substrate accommodating portion 70a. In addition, a claw portion 76 that engages with a cutout portion (not shown) of the control substrate 62 is provided in the substrate housing portion 70a. The claw portion 76 can be bent and deformed, and the control board 62 is fixed by engaging the claw portion 76 with a notch (not shown). Mold holes 78 for removing the mold are formed in portions corresponding to the protrusions 77 (see FIG. 10) provided at various locations on the claw portion 76 and the substrate housing portion 70a.
また、本実施形態の電装品ボックス70の右側面部73の外側面には、端子台取付板61を設置するための取付板設置部70bが設けられている。この取付板設置部70bには、図11に示すように、電装品ボックス70の内部側及び外部側(Y方向)に撓み変形可能な爪部80A及び80Bが設けられている。この爪部80A及び80Bの各々は、右側面部73をコの字状に型抜くことによって形成されている。爪部80Aは、X方向の一方側を支点としてX方向の他方側が撓むように構成されており、且つ、爪部80Bは、X方向の他方側を支点としてX方向の一方側が撓むように構成されている。このように構成すれば、爪部80Aに挟まれた配線65(図12参照)の抜け方向と、爪部80Bに挟まれた配線65の抜け方向とが互いに反対方向となるので、爪部80A及び80Bに挟まれた配線65の固定が外れるを防止することができる。これにより、配線65の処理が容易になる。
Further, on the outer side surface of the right side surface portion 73 of the electrical component box 70 of the present embodiment, a mounting plate installation portion 70b for installing the terminal block mounting plate 61 is provided. As shown in FIG. 11, the mounting plate installation portion 70b is provided with claw portions 80A and 80B that can bend and deform on the inner side and the outer side (Y direction) of the electrical component box 70. Each of the claw portions 80A and 80B is formed by punching the right side surface portion 73 into a U-shape. The claw portion 80A is configured so that the other side in the X direction is bent with the one side in the X direction as a fulcrum, and the claw portion 80B is configured so that one side in the X direction is bent with the other side in the X direction as a fulcrum. Yes. If comprised in this way, since the removal direction of the wiring 65 (refer FIG. 12) pinched | interposed into the nail | claw part 80A and the removal direction of the wiring 65 pinched | interposed into the nail | claw part 80B will become mutually opposite directions, claw part 80A. And it is possible to prevent the wiring 65 sandwiched between 80B from being unfixed. This facilitates processing of the wiring 65.
そして、本実施形態では、図11に示すように、爪部80Aの外側面(端子台取付板61に対向する面)には、突起部81Aが形成されていると共に、爪部80Bの外側面(端子台取付板61に対向する面)には、突起部81Bが形成されている。この突起部81A及び81Bは、Z方向に延在するように形成されている。図12に示すように、爪部80Aは、その突起部81Aが取付板設置部70bに設置される端子台取付板61に押圧されて、電装品ボックス70の内側に撓む。この際、爪部80Aが電装品ボックス70の内側に撓むことによって、当該電装品ボックス70内に引き回される配線65を挟持する構造となる。なお、図12では、爪部80Aについて記載したが、爪部80Bについても同様であるのでその説明を省略する。これにより、電装品ボックス70内の配線65を爪部80A及び80Bで固定することが可能となる。この図12では、配線65を突起部81Aの手前で固定したが、図13に示すように、配線65を突起部81Aを乗り越えた位置で固定してもよい。この場合、突起部81Aが、配線65の抜け防止手段として機能するので、より強固に配線65を固定することが可能となる。
And in this embodiment, as shown in FIG. 11, while the protrusion part 81A is formed in the outer surface (surface facing the terminal block attaching plate 61) of the claw part 80A, the outer surface of the claw part 80B. A protrusion 81B is formed on the (surface facing the terminal block mounting plate 61). The protrusions 81A and 81B are formed so as to extend in the Z direction. As shown in FIG. 12, the projection 81 </ b> A of the claw portion 80 </ b> A is pressed by the terminal block attachment plate 61 installed on the attachment plate installation portion 70 b, and bends inside the electrical component box 70. At this time, the claw portion 80 </ b> A bends to the inside of the electrical component box 70, whereby the wiring 65 routed in the electrical component box 70 is sandwiched. In FIG. 12, the claw portion 80A is described, but the same applies to the claw portion 80B, and the description thereof is omitted. As a result, the wiring 65 in the electrical component box 70 can be fixed by the claw portions 80A and 80B. In FIG. 12, the wiring 65 is fixed before the projection 81A. However, as shown in FIG. 13, the wiring 65 may be fixed at a position over the projection 81A. In this case, since the protrusion 81A functions as a means for preventing the wiring 65 from coming off, the wiring 65 can be more firmly fixed.

The lower end surface of the flange portion 49 is close to or in contact with the upper end surface of the inner wall portion 53b. Therefore, a gap F formed between the flange 49 and the edge 43b, a gap G formed between the flange 49 and the top surface 43a, and between the flange 49 and the upper end surface of the inner wall 53b. Thus, the gap D formed in is substantially eliminated, so that it is possible to reliably prevent water from entering the electrical component between the flange 49, the top plate 43, and the inner wall 53b.
