Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a housing for a small electronic device. Specifically, a housing for a small electronic device capable of connecting a plurality of small electronic devices such as a small server in a horizontal direction and a vertical direction without lowering the design, and a connection structure of the housing for a small electronic device. About.

[0002]

2. Description of the Related Art It is desirable that small electronic devices such as computers are stably installed on a horizontal table. For this reason, a box-shaped housing having a low height is often used. However, since an installation area is required, a housing for vertical installation is often used in recent years. The housing has a risk of falling due to an earthquake or the like, and is often provided with support legs or the like for preventing the housing from overturning.

In recent years, a server or the like may be used by connecting a plurality of devices in order to increase the capacity. When such electronic devices are arranged in a horizontal direction, a larger installation area is required. For this reason, they are often used stacked in the vertical direction. In such a case, a plurality of devices are often stably stacked using a dedicated support frame.

[0004] For example, as disclosed in Japanese Utility Model Application Laid-Open No. 62-114410, there has been proposed a connection structure of a housing configured so that a plurality of small electronic devices can be connected using a magnetic force. The connection structure has a configuration in which a magnet is arranged on the inner surface of the side wall, and positioning protrusions and recesses are provided on the side wall of each housing to be connected.

In the case connecting structure described in the above publication, a magnet is arranged inside the case of the electronic device so as not to deteriorate the appearance. However, the influence of the magnetic force acts directly on the inside of the electronic device, which may cause a malfunction of the electronic device or adversely affect the magnetic storage device and the like.

Also, since the positioning projections and depressions are provided on the side wall, it is inevitable that the appearance of the housing is greatly reduced.

Japanese Patent Application Laid-Open No. H5-21139 discloses a configuration in which the influence of a magnet does not reach the inside of the housing.
No. 9 discloses this.

[0008] The connecting structure described in the above publication is formed by forming a concave portion outside the side wall portion and arranging a magnet in the concave portion. By arranging the magnet outside the housing,
Although the magnetic force can be prevented from reaching the inside of the housing, the appearance is unavoidable because the connecting structure protrudes outside the housing. In addition, since the amount of protrusion is large even in a non-connected state, the connecting mechanism hinders a small device.

[0009] The present invention solves the above-mentioned conventional problems, and a magnet can be arranged outside a housing only when necessary to connect a plurality of housings. It is also an object of the present invention to provide a case for a small electronic device and a connection structure thereof, which can cope with the case where the external appearance is not deteriorated.

[0010]

Means for Solving the Problems To solve the above problems, the present invention takes the following technical means.

The invention described in claim 1 of the present application comprises a winding drum unit integrally formed from upper and lower wall portions and front and rear wall portions, and left and right side wall portions covering both side openings of the winding drum portion. A small electronic device housing in which a wall portion is formed by a metal plate, and a resin plate attached to the left and right side wall portions, and the resin plate is fixed to the left and right side wall portions or the winding drum portion, A connecting member capable of connecting and holding adjacent housings via a magnet member is provided.

In the present invention, all the walls are formed of metal plates. The type of the metal plate is not particularly limited, but it is desirable to use a metal plate having an electromagnetic wave shielding performance. By covering the electronic device with the metal plate, external electromagnetic waves can be prevented from adversely affecting the electronic device. In addition, it is possible to prevent electromagnetic waves generated inside from leaking to the outside.

When the housing is formed only of metal, appearance is often deteriorated. On the other hand, a housing entirely formed of resin is also provided. However, there is a problem that an electromagnetic wave shielding mechanism is required, and the cost is increased. In the present invention, the appearance design is improved without reducing the electromagnetic wave shielding effect by adopting a metal plate for the winding drum portion and the side wall portion of the housing and attaching the resin plate to the side wall portion. The form of the resin plate is not particularly limited. For example,
It is also possible to adopt a three-dimensional plate with an uneven pattern, which increases the degree of freedom in design. Therefore, a housing having an unprecedented appearance can be configured.

According to the present invention, two or more electronic devices can be connected in a state where the side walls to which the resin plates are attached face each other. To perform the above connection, a connection member is provided. The connecting member has a function of connecting and fixing the resin plate to the metal housing itself, and a function of connecting the opposing electronic devices via a magnet member.
For this reason, unnecessary parts are eliminated, and the appearance can be improved while reducing the cost. In addition, even in a non-connected state, the appearance is improved because the resin plates are arranged on both sides. The number of the connection members is set according to the size of the housing and the like.

Further, in the present invention, the magnet member is not disposed inside the housing, but is disposed between the connecting members when necessary. By arranging the magnet member outside the housing, there is little possibility that the electronic device will be adversely affected.

In the present invention, the metal housing includes a winding drum unit formed integrally with the upper and lower wall portions and the front and rear wall portions, and left and right side wall portions covering both side openings of the winding drum portion. And
Resin plates are attached and fixed to the left and right side walls.
With the above configuration, a housing with a design that has not existed in the past can be formed. In addition, by arranging surfaces having a large area on the left and right side wall portions, the rigidity of the housing itself is increased.

The connecting member may be screwed to a screw means provided on the side wall or the winding drum through a through hole provided in the resin plate. And a head extending and formed at one end of the screw shaft portion for clamping and fixing the resin plate, and having a suction surface to be attracted to the magnet member. Further, an engagement hole that opens outward in the axial direction and positions the magnet member can be provided.

The resin plate can be connected and fixed to the side wall without providing a separate screw member by the connecting member. In addition, since the resin plate can be pressed between the side wall and the resin plate by the head of the screw shaft, the mounting strength of the resin plate can be secured. Further, since the head is provided with the suction surface for connection, the suction force is directly transmitted to the side wall, and the connection strength between the housings can be increased. In addition, since the engagement hole for positioning the magnet member is provided in the head, the connection accuracy between the housings is improved.

Further, as in the invention described in claim 3 of the present application, an inner peripheral thread portion can be provided in the engagement hole. The inner peripheral thread portion can not only increase the connection strength by fixedly connecting the magnet member, but also
It is also possible to attach a leg, a cap, and the like via a screw member screwed to the inner peripheral screw portion.

By providing the leg portion on the side wall portion via the connecting member, the posture of the electronic device can be changed and the electronic device can be placed on a table or a plurality of housings can be stacked so that the housings are laid down. It is also possible to connect. For this reason, not only can it cope with vibration and shaking, but also space can be saved. When the connecting member is not used, a cap or the like can be attached to improve the appearance.

According to a fourth aspect of the present invention, there is provided a connecting member provided with an attracting surface attracted by a magnetic force, the connecting member being mounted on a facing surface of a housing to be connected, and the attracting surfaces on the side of the connecting member being provided on both sides. And a magnet member having a suction surface for sucking and holding the magnetic member, and an engaging projection provided on the suction surface on the magnet member side is engaged with an engagement hole provided on the suction surface on the connection member side. The present invention relates to a connection structure of a housing for a small electronic device that positions and holds a housing with a magnetic force.

The connecting structure of the housing using the connecting member and the magnet member can be applied to a case other than a housing having a resin plate. In particular, since the magnet member can be arranged outside the housing and attached only when necessary, the side surface of the housing is simplified, and there is no protrusion. Therefore, it is possible to improve the design.

Further, since the connecting member and the magnet member are connected not only by the magnetic force but also by the engagement of the engaging hole and the engaging projection, a high connecting strength can be obtained.

According to the invention described in claim 6 of the present application, the magnet member includes a magnet having a holding hole penetrating in the axial direction, and a shaft fitted in the holding hole, wherein the shaft is It is provided with a fitting shaft portion fitted into the hole, and a pair of engaging projections formed to extend at both ends of the fitting shaft portion and engaged with the engaging holes of the connecting member. . Since the engagement protrusion can be provided integrally with the magnet member, attachment and detachment becomes extremely easy.

According to the invention described in claim 7 of the present application, while the inner peripheral thread portion is provided in the engaging hole, one of the engaging projections is screwed to the inner peripheral thread portion provided in the engaging hole. The outer peripheral thread portion is provided. Since the magnet member can be connected to one of the housings to be connected by a screw, the connection strength is further increased.

According to an eighth aspect of the present invention, there is provided a connecting structure in which a plurality of small electronic device casings according to the first aspect are arranged and connected in a horizontal direction vertically via the magnet member. About. By connecting the housings arranged in the horizontal direction, the earthquake resistance is greatly increased, and the possibility of falling is reduced.

On the other hand, according to a ninth aspect of the present invention, a plurality of small electronic device casings according to the first aspect are vertically stacked so as to be laid down in a horizontal direction, and connected via the magnet member. In addition, a leg member is connected to the connection member located on the lower surface of the lowermost housing via a mounting screw screwed into the inner peripheral thread portion.

By laminating the casings in a state where the posture of the casings is rotated by 90 degrees, the installation space can be greatly reduced. Further, since a leg member such as a rubber leg can be provided by using the above-mentioned connecting member located on the lower surface of the lowermost housing, a separate frame member or the like is not required. As the leg member, a member attached to another place of the housing may be used.
