Abstract

PROBLEM TO BE SOLVED: To improve separation, to make a material display visible so as to shorten an arrangement time, and to improve the recycling of useful resources by pressing and fixing a metallic shield member and a net for foreign body mixture prevention in a case formed of synthetic resin. SOLUTION: The net 9 is hooked to a hook rib 6a of an upper case 6 and the net 9 is pressed in a pressing-in pin 6b. Then a shield plate 10 is pressed in pressing-in pins 6b and 6c and fixed to the upper case 6. The net 9 and shield plate 10 are fixed by using and pressing in the pressing-in pin 6b of the upper case 6 in common, so the need for a secondary process such as welding and adhesion is eliminated to shorten the operation time and make separation easy. Further, a material display hole 10a is bored in the shield plate 10 where the material display on the upper case 6 is visible. Consequently, the material of the synthetic resin can be confirmed before separating operation and the arrangement time can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a personal computer.

[0002]

2. Description of the Related Art Conventionally, a stationary information processing apparatus has a shielding effect so as not to emit an electromagnetic wave that would impair the function of surrounding electronic devices when the information processing apparatus is used. The product was covered with components. Further, a fan is provided inside the apparatus to forcibly exhaust air inside the apparatus to the outside of the apparatus, and accordingly, air is taken in from a ventilation port provided in a case to suppress a rise in temperature inside the apparatus.

As a typical structure of these information processing apparatuses, as shown in FIG. 1, a hard disk drive 1 for reading and writing information and a floppy disk drive 2
And a CD-ROM device 3 for reading information, a control board 4 for controlling them, a power supply 5 for supplying power, and upper and lower casings 6 and 7 and a front panel 8 which are housings for covering these components. ing.

As a shield structure of such an information processing apparatus, a shield member welding method in which a metal shield member is welded inside a synthetic resin case is often used. This method is lower in cost than a surface treatment method in which conductive coating or plating is performed on the inside of the synthetic resin.

[0005]

However, if the shield member covers the inside of the synthetic resin case, the material symbol displayed on the inside of the synthetic resin case cannot be seen. bad.

In addition, since the air vent is open to prevent the temperature inside the apparatus from rising, it is necessary to attach a net or the like to the case with a tape, an adhesive or the like in order to prevent foreign matter from entering.

[0007] Therefore, achieving a structure having a shielding effect and also improving separability and assemblability has been a very serious technical problem in the present age when recyclability is important.

[0008]

SUMMARY OF THE INVENTION In view of the above, the present invention provides
In an information processing device having a synthetic resin case and a metal shield member as a housing, the metal shield member and the foreign matter prevention net can be easily pressed into and fixed to the synthetic resin case. Therefore, the structure has improved separability and good recyclability.

According to this structure, the case of the synthetic resin is
The metal shield member and the foreign matter entry preventing net can be easily fixed by press-fitting, and can be easily separated by making a hole near the press-fit portion of the metal shield member.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a view for explaining a method of attaching a metal shield member and a net for preventing foreign matter from entering in the information processing apparatus according to the present invention.

A net 9 is attached to the hooking rib 6a of the upper case 6.
And fix the net 9 to the press-fit pin 6b of the upper case 6 by press-fitting.

Next, the shield van 10 is press-fitted into the press-fit pins 6b and 6c and fixed to the upper case 6. At this time, the press-fit pin 6b is press-fitting the shield van 10 and the net 9.

In this embodiment, the fixing of the net 9 and the shield bun 10 is performed by using the press-fitting pins 6b of the upper case 6 and press-fitting, thereby eliminating the necessity of a secondary process such as welding or bonding, and shortening the working time. And separation is easy.

In this embodiment, as shown in FIG. 3, a material display hole 10a is provided in the shield van 10 where the material display displayed on the upper case 6 can be seen. The material of the synthetic resin can be confirmed before the separation work, and the setup time can be reduced. Also, if the lot display is displayed near the material display, it is easy to track the lot of the part.

In this embodiment, a separating hole is provided near the press-fit pin 6c of the upper case 6. For example, a separation hole is formed in the shield van 10 near the press-fit pin in the center of the upper case.
By providing the holes 10b and lifting the shield bun 10 by hooking the holes 10b with the driver 11 at the time of separation as shown in FIG. 4, a trigger for separating the shield bun 10 from the upper case 6 can be obtained, and the separation becomes easy. Further, the hole for viewing the material indication may be a separation hole.

[0017]

As described above in detail, according to the present invention, the metal shield member is fixed to the synthetic resin by press-fitting, so that there is no secondary process after press-fitting, and the net for preventing foreign matter from entering and the metal shield. The press-fitting of the members can be shared by the same press-fitting pin, and the fixing method is press-fitting, so that the separation is good, the material display can be seen, the setup time can be shortened, and finite resources can be reused, that is, the recyclability is improved. .
