One end of the connecting portion 33 is connected to the flat plate portion 32 , and the other end thereof is connected to the side plate 23 around the opening 31 . Thus, the connecting portion 33 connects the flat plate portion 32 and a part of the housing 20 . In the present embodiment, one end side of the connecting portion 33 , that is, a boundary portion between the connecting portion 33 and the flat plate portion 32 is referred to as an end portion 331 on the flat plate side. In addition, the boundary portion between the connecting portion 33 and the side plate 23 on the other end side of the connecting portion 33 is referred to as an end portion 332 on the side plate side. The connecting portion 33 is formed to extend toward the inside of the casing 20 by forming a plurality of bent portions between the both end portions 331 and the end portion 332 . Therefore, the side plate 23, the flat plate portion 32, and the connection portion 33 are not joined by welding or an adhesive, and are not joined using fastening members or the like, but are integrally formed using metal plates of the same material. That is, the case 20, the flat plate portion 32, and the connection portion 33 are integrally formed.

As shown in FIG. 5 , in the unbent state of the connecting portion 33 , the connection portion 33 is formed in a form that bends upward and downward and meanders between the end portion 331 on the flat plate side and the end portion 332 on the side plate side. . Furthermore, in the state where the connecting portion 33 is not bent, the end portion 331 on the flat plate side is located at approximately the same height as the end portion 332 on the side plate side, or is located below the end portion 332 on the side plate side, that is, the connecting portion. 321 side.

Furthermore, in the present embodiment, the width dimension of the connection portion 33 is set to be 6 times or more the thickness dimension of the side plate 23 , that is, the thickness dimension of the connection portion 33 even at the narrowest point. For example, when the thickness dimension of the side plate 23 is 0.6 mm, the width dimension of the connection part 33 is set to 3.6 mm or more at the narrowest part W.

As shown in FIG. 2 , the terminal strip 40 is detachably provided on the terminal strip mounting portion 30 .

The pressing step (step S11 ), as shown in FIG. 5 , is a step in which the opening 31 , the flat plate 32 , and the connecting portion 33 are formed by pressing a flat metal plate serving as the base material of the side plate 23 . as one. In addition, in the pressing step (step S11 ), the locking portion 322 of the terminal plate 40 is also formed by pressing at the same time. After the pressing process is performed, the bending process is performed (step S12).

In the bending step (step S12), as shown in FIG. 3 and FIG. 6 , it is a step of bending the flat plate portion 32 so that it inclines toward the inside of the housing 20 using the connection portion 321 as a fulcrum, and so that The connecting portion 33 is bent so as to extend toward the inside of the housing 20 . In the bending step, the connecting portion 33 is bent along the dotted line L1 to the dotted line L4 in FIG. 5 , and a plurality of bent portions 333 are formed along the dotted line L1 to the dotted line L4. In such a case, in the connecting portion 33 , a mountain fold portion and a valley fold portion are alternately formed at portions indicated by the dotted lines L1 to L4 . Thus, the terminal board mounting portion 30 is integrally formed on the side plate 23 . In addition, in the bending step (step S12 ), the triangular rib 324 shown in FIG. 3 is also formed at the same time. Then, after the bending step (step S12 ), the terminal strip 40 is attached to the flat plate portion 32 of the terminal strip attaching portion 30 .

According to the embodiment described above, the outdoor unit 10 includes the box-shaped casing 20 and the terminal strip mounting portion 30 . The terminal strip mounting portion 30 is provided on the side plate 23 constituting the case 20 , and a terminal strip 40 to which electric wiring is connected is detachably provided on the terminal strip mounting portion 30 . The terminal strip mounting portion 30 has an opening portion 31 , a flat plate portion 32 , and a connecting portion 33 .

The flat plate portion 32 is provided inside the opening portion 31 in the planar direction of the side plate 23 . The flat plate portion 32 has a connection portion 321 in which a part of the periphery is connected to the side plate 23 . The flat plate portion 32 is inclined so as to be bent toward the inside of the housing 20 with the connecting portion 321 as a fulcrum. A terminal board 40 is detachably attached to the flat plate portion 32 . Furthermore, the connecting portion 33 connects the side plate 23 and the flat plate portion 32 .

And when manufacturing the side plate 23 of the case 20 of the outdoor unit 10, as shown in FIG. 4, a pressing process (step S11) and a bending process (step S12) are included. The pressing step (step S11 ) is a step of pressing a flat plate member to integrally form the opening 31 , the flat plate 32 , and the connecting portion 33 . In this case, the opening 31 passes through the side plate 23 to communicate the inside and outside of the casing 20 . The flat plate portion 32 is provided inside the opening 31 in the planar direction of the side plate 23 , has a connection portion 321 in which a part of the periphery is connected to the side plate 23 , and is detachably attached to the terminal board 40 . The connecting portion 33 connects the side plate 23 and the flat plate portion 32 . The bending step (step S12 ) is a step of bending the flat plate portion 32 so as to incline toward the inside of the case 20 using the connecting portion 321 as a fulcrum, and extending the connecting portion 33 toward the inside of the case 20 . Way to bend.

Accordingly, the connecting portion 33 connects the flat plate portion 32 and the side plate 23 . Therefore, in the flat plate portion 32 where the inward pressure of the casing 20 is easily applied when the outdoor unit 10 is installed or wiring work during maintenance is performed, the inward pressure of the casing 20 can be increased. rigidity. That is, the connecting portion 33 functions as a reinforcing member for reinforcing the flat portion 32 , and can increase the rigidity of the flat portion 32 , that is, the rigidity of the terminal strip mounting portion 30 .

Furthermore, the connecting portion 33 is formed to extend toward the inside of the housing 20 by forming a plurality of bent portions 333 . Thus, the side plate 23, the flat plate portion 32, and the connection portion 33 are not joined by welding or an adhesive, and are not joined by fastening members, but are integrally formed of the same material, in this case, a metal The board is formed into one piece. In other words, the side plate 23 , the flat plate portion 32 , and the connection portion 33 are integrally formed of the same member without any joining portion.

That is, the connecting portion 33 is not a metal plate part or the like that is separately formed from the side plate 23 and the flat plate portion 32, but is integrally formed with the side plate 23 and the flat plate portion 32, so that there is no need to separately install the terminal plate mounting portion 30 in order to improve the rigidity of the terminal plate mounting portion 30. Install reinforcement members such as sheet metal parts. Therefore, it is possible to suppress an increase in the number of components due to the provision of the connecting portion 33 .

The width dimension of the connection portion 33 is set to be 6 times or more the thickness dimension of the side plate 23 , that is, the thickness dimension of the connection portion 33 . If the width dimension of the connection portion 33 is too small relative to the thickness dimension of the connection portion 33 , the rigidity of the connection portion 33 decreases. Furthermore, if the rigidity of the connecting portion 33 is low, not only the connecting portion 33 cannot sufficiently function as a reinforcing member of the terminal strip mounting portion 30 , but also breakage occurs during processing, making processing difficult. On the other hand, it was found that when the width dimension of the connection portion 33 is 6 times or more the thickness dimension of the connection portion 33 , the rigidity of the connection portion 33 can be sufficiently ensured and the processing becomes easy. According to the above configuration, the rigidity of the connecting portion 33 can be ensured and the workability can be improved.

In addition, the length dimension, arrangement, etc. of the connection part 321 or the connection part 33 are not limited to the above-mentioned, and can be changed suitably according to the size, arrangement, etc. of the flat plate part 32.

Moreover, the housing 20 is not limited to a box-shaped housing formed by combining the independently formed front plate 21, top plate 22, and side plates 23, and may be formed integrally with the front plate 21, top plate 22, and side plates 23. case.

As mentioned above, although one embodiment of this invention was described, this embodiment is presented as an example, and it does not intend limiting the scope of the invention. The novel embodiment described above can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.
