Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for a convection guide plate in an electronic device.

In general, when fixing an electronic unit whose center of gravity is toward the back of a frame or case that has a long depth, increase the number of fixing screws to the front of the frame, etc. A method of strongly fixing on the side has been used, but this requires a large amount of space for fixing. Alternatively, a method of fixing the electronic unit by providing a screw portion at the back of the frame may be considered, but it would be difficult to attach and remove the electronic unit only by operating from the front. Therefore, in these methods, if the convection induction plate that induces the heat generation of the electronic unit is to have the role of supporting the electronic unit directly above it, it will give more space than necessary or complicate the structure, and therefore the front side Consideration must be given to transmitting the fixing force to the back.
Regarding this type of convection guide plate, Japanese Patent Application Laid-Open No. 1986-
No. 105699 is known, but in this known example, no particular consideration is given to the support structure of the electronic unit on the back side of the frame.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and to provide a simple mounting structure for a convection guide plate that also serves as a shelf for supporting an electronic unit and maintains an accurate angle of inclination.

The present invention includes a plurality of electronic units and an inclined surface having a certain angle with respect to a horizontal plane, and an inclined surface bent approximately perpendicularly from the inclined surface in order to promote convection within an electronic device housing the electronic units. An electronic device in which a convection guide plate having a horizontal end face located parallel to the electronic unit is attached to a frame column, wherein the frame column has a part of the convection guide plate on its front side. a machined part consisting of a screw fixing part for tightening the screws, a holding part for inserting and holding another part of the convection guide plate on the back side thereof, and a support part for supporting the lower end of the electronic unit; The convection guide plate is attached to the frame column by the holding part and the screw fixing part of the machined part, and the electronic unit has its lower surface connected to the horizontal end face part of the convection guide plate and the support part of the machined part. It is characterized in that it is configured to be supported by.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view of a casing to which the present invention is applied, and the structure thereof will be briefly described below.

First, the right pillar 100 and the left pillar 120 have shelf mounting parts 101 and 121 on the front surface with screw holes 102 and 122 for mounting an electronic unit (hereinafter referred to as a shelf), and a ceiling plate 140 above them. Mounting holes 103, 123 for mounting
At the bottom thereof, there are mounting holes 104, 124 for attaching the bottom plate 150, and at the center thereof there are bent parts 105, 125 that protrude into a rectangular shape to increase the mechanical strength of the right and left columns themselves. Back plate 1 on the back
Mounting parts 106 and 126 are provided with screw holes (not shown) for mounting the above-mentioned ceiling plate 140, bottom plate 150, and back plate 160.
The left column 120 and the right column 1 have the structure described above.
00 with screws 90.

In addition, hook attachment holes 107, 10 for cargo handling are provided at the top and bottom of the bent portions 105, 125.
8, 127 and 128 are provided, and
The space between the mounting parts 106, 126 and the bent parts 105, 125 is determined based on the assumption that the back plate 160 is laid down on the floor during cargo handling.
It constitutes handling spaces 109 and 129 for cargo handling.

In the present invention, the shield 170 and the convection guide plate are attached to the stone pillar 100 and the left pillar of the frame having such a structure, which will be explained in detail below using the perspective views of the main parts shown in FIGS. 2 and 3. Explain.

As shown in FIG. 2, on the side of the convection guide plate 180, there is a bent front side fixing part 181, an inclined surface 182 that is given a certain angle with respect to the horizontal plane, and a depth direction of the inclined surface 182. It has protrusions 183 at appropriate positions. Furthermore, a horizontal end surface 184 is provided which is long in the depth direction at right angles to the front side fixing portion 181 and is bent approximately perpendicularly from the inclined surface. The front side fixing part 181 has a screw hole 18 that is to be fastened with a screw hole 122 provided in the left column 120 and a screw 190.
5. Furthermore, as shown in detail in FIG. 3, the left column 120 is provided with an aperture 131 having a slit 130 at a position corresponding to the aforementioned protrusion 183. Incidentally, the right column 100 is also subjected to similar machining at a position symmetrical to that in FIG. 3.

The convection guide plate 180 can be fixed to the right columns 100 and 120 by pushing it in from the front side until the protrusion 183 is inserted into the slit 130, and then fastening the front fixing part 181 with the screw 190 at that point. Further, the shelf 170 can be mounted on the frame by sliding it on the horizontal end surface 184 of the convection guide plate 180 and fastening it to the left column and right column with screws on the front side as necessary.

As described above in detail, according to the present invention, the convection guide plate can be supported on the back side of the frame without using screws, and heavy objects can be supported there. In other words, it will also serve as a support shelf for mounting the shelf directly above. Furthermore, it is possible to maintain an accurate inclination angle of the convection guide plate with a simple structure, which is extremely practical.
