本発明は電子機器用筐体に関し、特に実装電子
機器の静電気障害を防止するため、筐体本体の外
装板と扉の外装板とを電気的に接続可能とした電
子機器用筐体に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a housing for electronic equipment, and in particular, in order to prevent electrostatic damage to mounted electronic equipment, the exterior plate of the housing body and the exterior plate of the door are electrically connected. The present invention relates to a housing for electronic equipment that can be connected to a casing for electronic equipment.
従来、電子機器用筐体構造では扉類の外装板、
筐体本体の外装板は美観およびサビ防止のため塗

Conventionally, in case structures for electronic devices, exterior panels for doors,
The exterior panel of the main body of the case was painted for aesthetic purposes and to prevent rust.

このための対策として、筐体本体の外装板および
扉類の外装板が帯電しない様これらをアースする
必要がある。 The problem here is that it takes a lot of man-hours to paint these exterior panels, and when the exterior panels of the main body of the casing and the exterior panels of the doors are assembled after painting, they do not interact with each other. This means that it is insulated. The former has the problem of increasing costs, and the latter has the problem that the exterior panels of the main body of the casing and the exterior panels of the doors are charged with static electricity due to external noise such as static electricity and radio wave noise, and when it exceeds a certain amount, it is discharged. Therefore, there is a problem in that the logic section of the electronic device mounted inside the case malfunctions, causing the system to go down.
As a countermeasure for this, it is necessary to ground the exterior plates of the housing body and the exterior plates of the doors so that they do not become electrically charged.
ところが、通常、筐体本体は一定の場所に設置
されるので、これをアースすることは簡単であ

大変難しい。そこで、従来、筐体本体の外装板を
アースしておき、これと扉類の外装板とを電気的
に接続することにより扉類の外装板を間接的にア
ースしている。 However, since the main body of the casing is usually installed at a fixed location, it is easy to ground it. However, the doors are removed from the housing when maintaining and inspecting the electronic equipment mounted inside the housing, and are opened and closed using hinges installed between them and the housing. It is very difficult to ground. Therefore, conventionally, the exterior plate of the casing body is grounded, and the exterior plate of the doors is electrically connected to the exterior plate of the doors to indirectly ground the exterior plate.
第１図および第２図に扉類の外装板を間接的に
アース可能にした従来の電子機器用筐体を示す。 FIGS. 1 and 2 show a conventional electronic device housing in which the exterior plate of the doors can be indirectly grounded.

設けられた蝶番により開けられたりする。 As shown in the perspective view of Fig. 1, the housing for electronic equipment consists of a housing body 1 and a door 2.
has been implemented. This figure shows the case body 1 closed with the door 2, but when maintaining or inspecting the electronic device 3, the door 2 may be removed from the case body 1 in the direction of arrow B. , and can be opened using a hinge provided between the housing body 1 and the housing body 1.

本体１の外装板７に固定してある。 In FIG. 2, the surface of the exterior plate 4 of the door 2 is finished with a paint 5 for aesthetic purposes and to prevent rust. The earth plate 6, which does not rust even without painting the surface, is directly joined to the exterior plate 4 without using the paint 5. On the other hand, the exterior plate 7 of the housing body 1 is also finished with the paint 5, and a ground plate 8 is connected to the exterior plate 7 for electrical continuity. and,
When the housing body 1 is closed by moving the exterior plate 4 of the door 2 in the direction of arrow C, the ground plate 6 and the ground plate 8 are electrically connected by the spring 9. Note that the spring 9 is fixed to the exterior plate 7 of the housing body 1 with screws 10.

で製造コストアツプを招くという欠点がある。 As described above, the exterior plate 7 of the casing body 1 and the exterior plate 4 of the door 2 are electrically connected via the ground plates 6 and 8, and by grounding the exterior plate 7 of the casing body 1, The exterior plate 4 of the door 2 is indirectly grounded. However, this conventional method has the disadvantage of increasing manufacturing costs because it requires many parts and many man-hours to attach them.

In order to achieve the above object, the present invention provides a housing for an electronic device that includes a housing body for mounting an electronic device therein, and a door that allows the housing body to be opened and closed. A panel is used as the exterior plate of the door, one side of which is a surface protection film made of an electrically insulating material, and the other side of which is made of a conductive material. The outer surface of the housing is such that when the housing body is closed by the door, the conductive material of the panel used as the exterior plate of the housing body and the conductive material of the panel used as the exterior plate of the door come into contact. These panels are characterized by having a contact surface bent portion.
