Moreover, each fastening surface 6a, 6b, 6c has comprised a series.
The fastening surface 6a is provided with fastening screw through holes 6ba and 6bb at a predetermined interval.
The fastening surface 6b is provided with fastening screw through holes 6ac, 3bb, 6ad at predetermined intervals.

  The bottom plate 2, the side plate 3, and the lower hinge 5 are integrally coupled by screwing using a common casing corner portion rigidity-strengthening coupling fitting 6. 2 (1), the state shown in FIG. 2 (2), the state shown in FIG. 2 (3), and then screwed in the state shown in FIG. 2 (3). The side plate 3 and the lower hinge 5 are coupled together through a common housing corner portion rigidity-strengthening coupling fitting 6.

  In the state of FIG. 2 (1), the bottom plate 2, the side plate 3, the lower hinge 5, and the common casing corner portion rigid reinforcement fitting 6 are all in a state before assembly.

  In the state of FIG. 2 (2), the housing corner portion rigidity-strengthening coupling fitting 6 is arranged at a predetermined position with respect to the side plate 3. In this state, the tightening screw through holes 3ba and 6ba are superposed, the tightening screw through holes 3bb and 6bb are superposed, the tightening screw through holes 6ac and 3ac are superposed, and the tightening screw through holes 6ad and 3ad are superposed. In addition, the through holes 6ae and 3ce for fastening screws are superposed.

In the state of FIG. 2 (3), the casing corner portion rigid reinforcing joint 6, the bottom plate 2, and the lower hinge 5 are all arranged at predetermined positions with respect to the side plate 3. In this state, the tightening screw through holes 5a, 3ba, 6ba are superposed, the tightening screw through holes 5b, 3bb, 6bb are superposed, the tightening screw through holes 2acc, 6ac, 3ac are superposed, and the tightening screw through holes are superposed. The holes 2acd, 6ad, 3ad are superposed, and the fastening screw through holes 2ace, 6ae, 3ce are superposed.
The side plate 3, the housing corner portion rigid reinforcing joint 6, and the lower hinge 5 are tightened through the common screws (including bolts) through the overlapped fastening screw through holes 5 a, 3 ba, 6 ba, and the side plate 3 and the housing corner are tightened. The partial rigidity reinforcing fitting 6 and the lower hinge 5 are integrally joined.
Similarly, overlapping tightening screw through holes 5b, 3bb, 6bb, overlapping tightening screw through holes 2acc, 6ac, 3ac, overlapping tightening screw through holes 2acd, 6ad, 3ad, overlapping Each of the tightening screw through holes 2ace, 6ae, and 3ce is also individually tightened through a common screw (including bolts), and the side plate 3, the corner corner portion rigid reinforcing joint 6, the lower hinge 5, and the bottom plate 2 are connected. Connect together.

In manufacturing the side plate 3, the clamping surface 3a is bent from the clamping surface 3b, the clamping surface 3c is bent from the clamping surface 3d, and the thickness of the side plate is sufficiently taken into consideration in consideration of workability and weight. Therefore, when the bottom corner 2 and the side plate 3 are joined to each other by screw fastening, the fastening surfaces 6a, 6b, and 6c of the housing corner portion rigid reinforcing joint metal fitting 6 are used. The effect of increasing the equivalent plate thickness to increase the strength against bonding by screw tightening, and the effect of enabling screw tightening bonding of the tightening surfaces 3a and 3c of the side plate 3 by the tightening surface 6a of the housing corner portion rigid reinforcing joint 6 Demonstrate.
Further, since the housing corner portion rigidity-strengthened coupling metal fitting 6 has the fastening surface 6b and the fastening surface 6c, the fastening surfaces 3a and 3c of the side plate 3 and the housing corner portion rigidity enhanced joint fitting 6 improve the strength of the fastening surface 6a. be able to.

  In combination with the above, the lower hinge 5 of the door 4 shown in FIG. 1 is screwed and joined to the case corner rigid reinforcement fitting 6 via the side plate 3, thereby providing sufficient strength to support the weight of the door 4. In addition, a hinge 31 is dotted on the side plate 23 as shown in FIG. 7 so that the weight of the door 26 is not applied to the upper and middle portions of the side plate 23, and the weight is mainly applied to the lower portion of the casing. It is possible to further improve the earthquake resistance by adopting a structure to receive.

  The other corner portions BBSC, CBSC, DBSC, ARSC, BRSC, CRSC, and DRSC are the same as or equivalent to those in the case of the aforementioned corner portion ABSC, and the detailed description of the structure and assembly procedure is omitted.

  Instead of the left and right independent unit mounting frames used in the conventional case shown in FIG. 7, the left and right integrated unit mounting frame frame 7 shown in FIGS. 1 and 6 is applied. Improve the seismic performance of the housing.

This is because the frame body 11 of the housing body is composed of the bottom plate 2, the side plate 3, and the top plate 12. Regarding the direction, the strength as the frame 11 tends to be insufficient. This is a tendency to be seen even at the time of welding joining, but it is noticeable by using screw joining.
In order to reinforce this, the left and right integrated unit mounting frame frame 7 is applied for the purpose of providing the same effect as the side plates in the front-rear direction.

  The left / right integrated unit mounting frame frame 7 shown in FIG. 1 has a structure as shown in FIG. 3 and has the same structure as that of the side plate 3 and door 4, and the electronic device unit is inserted into the wide flat portion 7a shown in FIG. And a through screw hole 7c for attaching an electronic device unit. Since the punch hole 7b is reinforced by a panel or the like for mounting an electronic device unit or an electric device, the left / right integrated unit mounting frame frame 7 has sufficient strength.

The left and right integrated unit mounting frame frame 7 shown in FIG. 1 is attached to the bottom plate 2 or the side plate lower portion by a screw screw through hole 7d and the top plate or the side plate upper portion to be screwed. In addition to joining each of the two points or more of the hole 7e, a fastening screw through-hole 7f that is joined to a plurality of side plate reinforcing metal fittings 8 shown in FIG. As shown in FIG. 1, if the fastening screw through-hole 7d cannot be directly screwed to the bottom of the bottom plate 2 or the side plate 3 due to the influence of the electronic device unit to be attached, etc., it can also be attached using the adapter fitting 14. And
Thus, the left and right integrated unit mounting frame frame 7 is a screw between the bottom plate 2, the left and right side plates 3, 3, and the top plate at the middle part of the bottom plate 2, the left and right side plates 3, 3, and the top plate. Since they are coupled by tightening, the left and right integrated unit mounting frame 7 has both an electronic device unit mounting function and a casing rigidity strengthening function.

In the case, a fixing metal fitting generally called a pre-chan 27 and having a cross section similar to the C type is used in the case, but a side plate reinforcing metal fitting 8 shown in claim 4 is applied.
Since the conventional pre-chan 27 was welded to the flat portion of the side plate 23 as shown in FIG. 7, there was an effect of suppressing the deflection of the welded portion. However, since the both end surfaces of the side plate were not joined, the entire side plate was twisted. The inhibitory effect was limited.

  The side plate reinforcing metal fitting 8 shown in FIG. 4 is joined to the tightening surface 3a (both left and right) of the side plate shown in FIG. 2, and exhibits the effect of suppressing twisting. This is because the structure of the side plate reinforcing metal fitting 8 has an effect of suppressing deformation in the X direction due to the effects of the upper and lower bent portion surfaces 8a and 8b and the central stepped portion 8c, and is appropriately predetermined in the vertical direction and the front and rear direction. Two points in the vertical direction with a distance (between the tightening screw through holes 8d and 8e and two points between the tightening screw through holes 8f and 8g), and two points in the front and rear direction (between the tightening screw through holes 8d and 8f and tightening) Since it is fixed at the screw through-holes 8e and 8g), it suppresses the degree of freedom of deformation of the fastening surface 3a (both left and right) of the side plate 3 in the height direction, thereby improving the earthquake resistance ( It becomes possible to mainly strengthen torsional deformation.

By constructing them comprehensively, it is possible to realize a screw joint casing that can be assembled relatively easily while maintaining the earthquake resistance that could not be achieved unless it was a welding technique that has been a special skill in the past.
In addition, the assembly of the main body portion of the electronic device housing 1 is performed by preparing necessary parts as illustrated in FIG. 5 and then assembling each part as illustrated in FIG. 6 by screwing.

As is apparent from the above, the first embodiment has the following technical features.
