Description of the Related Art In recent years, electronic devices such as computers and communication devices have been digitized and speeded up, and with the widespread use of these devices, electromagnetic interference waves emitted from the electronic devices to the surrounding space have become a problem. It's coming. As a countermeasure against this, a shield housing is used as a housing for housing the electronic device. In the shield housing, conductive packing is used to prevent electromagnetic waves from leaking through the gap between the opening and closing parts.

金属ばねが使用されている。FIG. 4 is a perspective view showing an example of a conventional shield housing structure, and FIG. 5 is a transverse sectional view thereof. The conductive packing 2 is provided on the peripheral edge of the front opening of the housing 1, and when the door 3 is closed, the conductive packing 2 also comes into contact with the peripheral edge of the door so that no gap is formed between the housing 1 and the door 3. Since the electrically conductive packing 2 needs to have a small electric resistance, a cylindrical rubber covered with a wire mesh or a metal spring is used.

シールド効果を著しく損ねる結果となる。In order to obtain a sufficient shielding effect, it is necessary to set the gap between the peripheral edge of the front opening of the housing 1 and the peripheral edge of the door 3 so that the conductive packing 2 is compressed by at least 20 to 30% or more. There is. Therefore, when the door 3 is closed, the repulsive force of the conductive packing 2 is always maintained.
On the peripheral edge of the front opening and the peripheral edge of the door 3. Even if the repulsive force of the conductive packing 2 is low, 100
There is about gf / cm. In the stationary large-sized housing 1, one side of the door 3 is as large as 1.5 m to 2 m, and since the housing body is made of a thick metal plate, a repulsive force of 10 kgf or more is constantly applied to the periphery of the door. Will be added.
Due to this repulsive force, the periphery of the door, especially in the vicinity of the center, is easily bent, and the compressibility of the conductive packing 2 is reduced in this portion, and in extreme cases, almost no contact is made. Become.

However, there is a drawback that the operation is troublesome. Further, since the stopper 10 projects outward from the surfaces of the housing 1 and the door 3, it is impaired in aesthetics and has a problem in safety for the human body. Furthermore, there is a disadvantage that the structure of the stopper 10 is complicated and therefore expensive. It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a shield housing structure having a high shielding effect and excellent operability, aesthetics, safety and economy.

As shown in FIG. 3, the leaf spring 5 is composed of a fixing portion 7 for the door 3, an engaging portion 8 for the housing 1, and a guide portion 9. The locking portion 8 is bent so that the angle θ 1 of the bent portion with the fixed portion 7 is 90 degrees, and the guide portion 9 has a bending portion angle θ 2 with the locking portion 8 in the range of 90 to 180 degrees. It is bent so that the inside angle is, for example, 135 degrees. The fixed part 7 is fixed to the door 3 by screws 11 (or welding).
Is fixed to the peripheral edge of the. When the door is closed, the leaf spring 5 is arranged so that the gap between the peripheral edge of the front surface of the housing and the peripheral edge of the door becomes a predetermined value, for example, the compression rate of the conductive packing 2 is 30%.
The size of the fixed part 7 is set. Thus, the leaf spring 5 has an extremely simple structure having only two bent portions and screw holes at most. As the material of the leaf spring 5, a type used as an inner spring material of stainless steel is suitable.

Spread the leaf spring 5 slightly. When the door 3 is further closed, the engaging portion 8 of the leaf spring 5 engages with the peripheral edge portion of the front opening of the housing 1, and at the same time, the leaf spring 5 that has been expanded until then is restored to the initial shape. On the other hand, when opening the closed door 3,
At the same time that the engaging portion 8 of the leaf spring 5 is disengaged from the peripheral edge portion of the front opening of the housing 1, the guide portion 9 comes into contact with the peripheral edge portion of the front opening of the housing 1 to spread the leaf spring 5. In this way, the guide portion 9
Serves to smoothly engage and release the engaging portion 8 with the peripheral edge of the front opening of the housing.

Even in this case, it is clear that the effects of the above-mentioned embodiment are not impaired. Further, in the above-described embodiment, the leaf spring 5 is not necessarily limited to the rotary opening / closing type door 3, but is structured to be attached to the side of the back cover 4 which opens and closes the back opening of the housing 1 by operating the screw 12. May be. Even in this case, the back cover 4 can be prevented from bending due to the repulsive force of the conductive packing 2, and the mounting screw 1
The effect of reducing the number of 2 is produced. Furthermore, the conductive packing 2 does not necessarily have to be a conductive packing for electromagnetic shielding, and may be a packing for airtightness against rainwater or the like. Even in this case, it is obvious that the same effects as those of the above-described embodiment such as the prevention of the bending of the door 3 are not impaired.
