[Detailed description of the device] [Industrial applications]

The present invention relates to an apparatus that accommodates a plurality of electronic devices inside a housing, and more particularly, to an improvement that improves the stability of a rail member that mounts an internal unit.

2. Description of the Related Art The applicant of the present invention has proposed various electronic device accommodating devices in, for example, Japanese Utility Model Publication No. 54-22910 "frame". Such a device is called a cubicle, and has a height as high as that of an operator, for example. However, since the degree of integration of electronic parts has been promoted in recent years, the same function can be realized even in a relatively small housing. For example, a cabinet having the same height as an office desk is sufficient, and it can be placed beside the desk in an instrument room. FIG. 3 is a configuration diagram of a cabinet, (A) is a front view, and (B) is a side view, showing only a frame without side plates attached. In the figure, reference numeral 11 denotes a mounting column having an L-shaped cross section, which has square holes formed at equal intervals in the axial direction and is provided on the side surface on the front side of the housing. Reference numeral 12 is a mounting pillar that is paired with the mounting pillar 11, and is provided on the side surface on the rear surface side of the housing. Two
Reference numeral 1 denotes a rail member having an L-shaped cross section, which is attached to the mounting columns 11 and 12, and is substantially horizontal, and an electronic device such as a nest for accommodating a large number of printed circuit boards therein is attached thereto. Reference numeral 30 is a base that supports the housing on the floor, and 40 is a lid that covers the flat surface of the housing. FIG. 4 is an explanatory view of the mounting state of the rail member 21, (A)
Is a perspective view and (B) is a plan view. The mounting post 11 includes a front side surface portion 11a parallel to the side surface and a front flange portion 11 parallel to the front surface.
The second mounting column 12 has a rear side surface portion 12a parallel to the side surface and a rear flange portion 12b parallel to the back surface. The rail members 21 are screwed to the front side surface portions 11a and the rear side surface portions 12a of the mounting columns 11 and 12, and the mounting columns 11 and 12 are symmetrical with respect to the center line IV-IV. However, since the screw projects inside the rail member 21, there is a risk that the screw may collide when inserting the inner unit and damage the inner unit. FIG. 5 is an explanatory view of another mounting state of the rail member 21,
(A) is a perspective view and (B) is a plan view. Mounting columns 11, 12
Has an asymmetrical shape with respect to the center point V, one end of the rail member 21 is locked in a square hole provided on the rear side surface portion 12a of the mounting column 12, and the other end is attached to the front brim portion 11b of the mounting column 11. Is screwed on. FIG. 6 is a sectional view of the rail member 21. Rail member 2
1 is a contact surface 2 parallel to the front side surface portion 11a and the rear side surface portion 12a
1a, a rail surface 21b in which a contact surface 21a is bent horizontally at the inside of the housing at a right angle, and a contact surface 21a is bent in a direction opposite to the rail surface 21b so that the front collar portion 1 of the mounting post 11 is bent.
A screw surface 21c that is screwed to 1b and a rail surface 2
The contact surface 21a is bent into a crank shape (substantially Z-shaped) in the opposite direction to 1b, and is formed with a locking surface 21d which is inserted into the square hole of the rear side surface portion 12a of the mounting column 12 and hooked.

[Problems to be solved by the device]

However, in the device shown in FIG. 5, the moment caused by the load directly acts on the screw fastening surface 21c, so that the screw is easily loosened. Further, when the entire rail member 21 becomes long, the torsion of the member due to the load increases, which causes a problem in smooth insertion and removal of the internal unit. The present invention solves such a problem, and an object of the present invention is to provide an electronic device accommodating device that has no protrusion on the inner unit insertion side and is less likely to loosen the screw.

[Means for solving problems]

The present invention that achieves such an object is provided with a first mounting column 11 mounted on the front side of the side surface of the housing, a second mounting column 12 mounted on the rear side of the side surface of the housing, and these mounting columns. An electronic device accommodating device having a rail member 21 attached to a holding member for holding an internal unit, which has the following configuration. That is, the first mounting pillar has an L-shaped cross section in the plane direction of the housing and a front side surface portion 1 parallel to the side surface.
1a and a front brim portion 11b parallel to the front surface. Further, the cross section of the second mounting column in the housing plane direction has an L shape, and has a rear side surface portion 12a parallel to the side surface and a rear collar portion 12b parallel to the back surface. The rail member has an abutting surface 2 parallel to the side surface.
1a, a rail surface 21b horizontally bent from the abutting surface to the inside of the housing, and an abutting surface bent in a direction opposite to the rail surface and screwed to the front flange portion of the first mounting post. The screwing surface 21c to be screwed and the contact surface in the opposite direction to the rail surface are bent into a crank shape (substantially Z-shaped) and inserted into an opening provided in the rear side surface portion of the second mounting pillar to be hooked. A locking member having a locking surface 21d, which locks against the front flange portion of the first mounting post when the screwing surface formed at the end of the rail surface on the screwing surface side is screwed. The surface 21e is provided.

[Action]

Each component of the present invention has the following functions. The contact surface enhances bending rigidity. The rail surface is used to guide the insertion and removal of the internal unit and to support the internal unit. The screwing surface is used to fix the rail member to the first mounting post. The locking surface is used to attach the rail member to the second mounting column and restrains the movement of the rail member in the axial direction. The stop surface is provided at the end of the rail surface and prevents loosening of the screw against a moment generated when the screwing surface is screwed.

【Example】

The present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view of essential parts showing an embodiment of the present invention, (A) is a plan view and (B) is a front view. In FIG. 1, components having the same functions as those in FIG. In the figure, the stopper surface 21e is a surface that is provided by extending the rail surface 21b to the vicinity of the end portion on the screwing surface 21c side. A reaction force is generated against the rotational force due to the moment generated when screwing. The operation of the apparatus thus configured will be described below. Second
The figure is an enlarged view of the part circled by the broken line II in Fig. 1, (A)
Is a plan view and (B) is a front view. The stopper surface 21e and the end surface of the mounting post 11 are in contact with each other without a gap. Therefore, the load W acts when the internal unit is housed, and as a result, the stopper surface 21e
A moment M acts on. On the other hand, the stop face 2
The reaction force R is generated from 1e, the rotation of the rail surface 21b is prevented, and the screw of the screwing surface 21c is not loosened. In the above embodiment, the cross-sectional shape of the mounting columns 11 and 12 is described as an L-shaped member, but the present invention is not limited to this, and the U-shaped or square shape having such a side surface is used. It may have a letter shape.

[Effect of device]

As described above, the present invention has the following practical effects. Since the locking surface 21d is first attached to the mounting column 12 and then the screwing surface 21c is screwed to the mounting column 11, the assembling work is easy, and as a result, the stopping surface 21e also easily strikes the mounting column 11. It is positioned at the stop position. Since the stopper surface 21e is provided, the screw is not loosened and the mounting stability of the rail member is enhanced.
