In this way, the terminal block 20, the terminal block base 30, and the terminal block cover 50 are integrally formed to constitute the terminal block storage box 100.

  Next, the attachment method of the apparatus main body 12 of the terminal block storage box 100 mentioned above is demonstrated. FIGS. 10A and 10B are diagrams illustrating an operation when the terminal block housing box 100 is aligned with the apparatus main body 12.

  When the terminal block housing box 100 is attached, first, the position where the terminal block 20 is attached is positioned. As shown in FIG. 10 (A), the positioning of the screw 82 projecting from the lower surface of the terminal block base 30 described above is formed in the upper surface 12a of the apparatus main body 12 as shown in FIG. 10 (B). This is done by inserting it into the hole 14. Thereafter, the screw 86 is screwed into the screw hole 54 of the first and second main body attachment portions 58A and 58B of the terminal block cover 50 and the corresponding screw hole 18 on the upper surface of the apparatus main body 12, whereby the terminal block cover 50 is fixed. It is attached and fixed to the upper surface 12 a of the apparatus main body 12. Thereby, the terminal block base 30 and the terminal block 20 integrally formed with the terminal block cover 50 are also attached and fixed to the apparatus main body 12.

  Next, the terminal block housing box 100 installed on the upper surface 12a of the apparatus main body 12 described above is rotated and installed from the first area S1 (first position) to the second area S2 (second position). An example of operation when the direction is switched will be described. FIG. 11 is a diagram when the terminal block housing box 100 is attached to the first region S1 of the apparatus main body 12. FIG. FIG. 12 is a diagram when the terminal block storage box 100 is removed from the first region S1 of the apparatus main body 12. FIG. FIG. 13 is a diagram when the terminal block storage box 100 is removed from the second region S2 of the apparatus main body 12. FIG. FIG. 14 is a diagram when the terminal block storage box 100 is attached to the second region S <b> 2 of the apparatus main body 12. In the following description, it is assumed that the terminal block storage box 100 is attached to the first region S1 in advance.

  First, the terminal block storage box 100 attached to the first region S1 of the apparatus main body 12 shown in FIG. 11 is removed. As shown in FIG. 12, the removal work can be easily performed by removing the two screws 86 of the body attachment portions 58 </ b> A and 58 </ b> B of the terminal block cover 50. In this manner, the integrally formed terminal block base 30 and terminal block 20 can also be removed at the same time.

  Next, as shown in FIG. 13, the terminal block housing box 100 is rotated by 180 ° around the shaft portion O of the terminal block cover 50, and protrudes from the lower surface of the terminal block base 30 into the positioning hole 36 in the second region S <b> 2.

As shown, the terminal block cover 50 is attached and fixed to the upper surface 12 a of the apparatus main body 12. In this example, since the wiring lead portions 56A and 56B are provided at the rotationally symmetrical positions of the side wall portions 50b and 50c of the terminal block cover 50, the wiring 60 is not sandwiched between the side wall surfaces 50c.

  As described above, in the present embodiment, since the terminal block cover 50 and the terminal block base 30 are integrally formed via the screw 80, it is not necessary to attach each individual member to the apparatus main body 12 separately. In this example, by attaching only the terminal block cover 50 to the upper surface 12 a of the apparatus main body 12, the terminal block base 30 and the terminal block 20 can also be attached to the apparatus main body 12 at the same time. Thereby, in this example, the number of screws 86 can be reduced to two, and the amount of work at the construction site can be greatly reduced. As a result, it is possible to prevent an assembly error or forgetting to tighten the screw 86.

  Even when the installation direction of the terminal block storage box 100 has to be changed, the terminal block 20 is removed integrally with the terminal block cover 50, so that the terminal block 20 is not damaged by the terminal block cover 50.

  In the present embodiment, the screw holes 32 and 52 for connecting the terminal block base 30 and the terminal block cover 50 are formed in the respective side wall portions (vertical surfaces) 30b, 30c, 50b and 50c, and the terminal block cover is formed. The screw holes 54 used when attaching 50 to the apparatus main body 12 are formed in the main body attaching portions (horizontal planes) 58A and 58B, and the screw holes 32 and 52 of the terminal block cover 50, the terminal block base 30, and the terminal block cover 50. And screw holes 54 connected to each other are formed on different surfaces. Since the installer generally performs the work by visually recognizing the apparatus main body 12 from above, the screw 80 is mistakenly attached to the screw holes 32, 52 of the side wall surfaces 30b, 30c, 50b, 50c of the terminal base 30 during the work. There is no possibility of screwing or removing the screwed screw 80 by mistake.

  Furthermore, in this embodiment, since the screw 82 protruding from the terminal block base 30 is inserted into the positioning hole 14 of the apparatus main body 12 and positioned, the screwing operation is performed, so that it is difficult to perform the operation visually. Even in a dim place, the terminal block storage box 100 can be easily positioned.

  It should be noted that the technical scope of the present invention is not limited to the above-described embodiments, and includes those in which various modifications are made to the above-described embodiments without departing from the spirit of the present invention.

  For example, although the terminal block 20 is attached to the terminal block base 30 side, it may be attached to the terminal block cover 50 side or may be attached to both sides.

  In the above-described embodiment, the main body attachment portions are provided at two locations on the terminal block cover 50. However, three or more locations may be provided to attach the terminal block cover 50 more stably.

  Further, in the above-described embodiment, the terminal block base 30 and the terminal block cover 50 are formed in a predetermined shape by bending a single flat plate, but the other members are joined together by welding to form the terminal block base 30 or the like. May be formed.
