[Industrial applications]

 The present invention relates to an electronic device housing that houses electronic circuit units, and more particularly to an electronic device housing that is used by stacking a plurality of electronic circuit units and that connects the electronic circuit units in the stacked electronic device housings to each other by a cable. ..

[0002]

[Prior Art]

 FIG. 7 shows a conventional stacked electronic device housing. Each electronic device housing 1 includes a bottom plate 2, a ceiling plate 3, left and right side plates 4, 5 and a front decorative plate 6. The left side plate 4 is provided with a cable wiring port 7, and a cable 8 is inserted into the cable wiring port 7, and these cables 8 are housed in each electronic device housing 1 as shown in the drawing. The omitted electronic circuit units are connected to each other and signals are transferred between the electronic circuit units.

[0003]

[Problems to be solved by the device]

 However, in the conventional electronic device housing, the cable 8 is exposed to the outside of the housing 1, so that the cable 8 is damaged when the electronic device housing 1 is attached, etc. There were problems such as disconnection and disconnection from the connector.

In order to store the cable 8 in the electronic device housing 1, the following configurations are possible. That is, as shown in FIG. 8, for example, a pair of end projecting portions 2a is projected from the end of the bottom plate 2 to form the cable wiring port 9 between the pair of end projecting portions 2a, and Similarly, a pair of end projections 3a is projected from the end of the ceiling plate 3 to form a cable wiring port 9 between the pair of end projections 3a. In order to cover the space formed by the projecting ends 2a of the side plate 4, the bottom plate 2 and the projecting end 3a of the ceiling plate 3, the side face decorative plate 10 indicated by the alternate long and short dash line is provided with the projecting end 2a and the projecting end 3a. A cable accommodating space is formed by attaching the front decorative plate 6 shown in FIG. By arranging the cable in this space, it is possible to prevent the cable from being exposed.

However, in this case, another problem arises in that the end protruding portion 2a of the bottom plate 2 and the end protruding portion 3a of the ceiling plate 3 become very weak in terms of strength. Then, the objective of this invention is to accommodate the cable which connects between the laminated electronic device housings, and to provide the electronic device housing which has sufficient strength.

 In order to achieve this object, an electronic equipment housing according to the present invention is a housing for electronic equipment in which a plurality of electronic circuit units are stacked, and a pair of end protrusions are provided at both left and right ends of the electronic equipment housing. Between the pair of end projections and the bottom plate with the cable wiring port formed between the pair of end projections, and between the pair of end projections at the left and right ends. The U-shaped opening consists of a ceiling plate with a cable port, a flat plate-shaped main plate with a U-shaped cross section, and a pair of bent parts bent from both ends of the main plate. The right side support plate whose upper end is fixed to the right end of the ceiling plate and the lower end is fixed to the right end of the bottom plate so that the section faces the outside of the housing, and the flat main plate part has a U-shaped cross section. And a pair of bent parts that are bent from both ends of the main plate part. The upper end is fixed to the left end of the ceiling plate and the lower end is fixed to the left end of the bottom plate so that the U-shaped opening faces the outside of the housing. Of the right side decorative plate attached so as to cover the U-shaped opening of the above, and the left side decorative plate attached so as to cover the above U-shaped opening of the left side support plate. The right-sided strut plate is provided at the upper end so that the U-shaped internal space communicates with the right-side cable wiring port of the ceiling plate and the right-side cable wiring port of the bottom plate, respectively. The pair of bent portions are in contact with the pair of end projections of the ceiling plate, and the pair of bent portions of the lower end are in contact with the pair of end projections of the bottom plate, and the left side support plate is provided. Indicates that the U-shaped internal space is the cable wiring port on the left side of the ceiling plate and the left side of the bottom plate. The pair of bent portions at the upper end are abutted against the pair of end projections of the ceiling plate and the pair of bent portions at the lower end are connected to the bottom plate so as to respectively communicate with the cable wiring port. It is characterized by being brought into contact with the pair of end projections. In such a configuration, it is desirable that the ceiling plate and the bottom plate have positioning engaging portions that position the upper and lower electronic device casings when the electronic device casings are stacked.

[0007]

[Action]

 A cable insertion space is formed inside the electronic device housing by the cable wiring opening on the bottom plate, the cable wiring opening on the ceiling plate, and the space inside the U-shape of the support plate. When the electronic device housings are stacked, the cable insertion spaces of the electronic device housings communicate with each other.

Therefore, the cable is exposed to the outside of the electronic device casing because the electronic circuit units of the laminated electronic device casing are connected to each other through the cable insertion spaces of the respective electronic device casings that are communicated with each other. Therefore, it is possible to prevent damage to the cable and disconnection from the connector, and to not spoil the appearance of the electronic device housing. In addition, the bent parts of the support plate contact the end projections of the bottom plate and the end projections of the ceiling plate, respectively, to reinforce them in strength, so that an electronic device housing with sufficient strength can be obtained. You can
