2. Description of the Related Art Recent LAN and WAN (Wide Ar)
With the spread of ea Network, a large number of personal computers (hereinafter referred to as “PCs”), network devices such as hubs, switches, routers (hubs are sometimes called “agents”) are connected to networks and their subnets. They are connected and share and communicate information frequently.

In order to cope with various communication modes in recent years,
Network devices are required to have multiple functions such as LAN functions and WAN functions, and at the same time, are required to have more communication devices such as PCs and higher processing capacity in order to cope with more communication traffic. . In addition, network equipment
With the recent miniaturization of communication devices, miniaturization is required. In addition, conventionally, there is a demand for diversification of installation of network devices, which is not limited to the conventional horizontal desktop, according to various usage and installation forms of customers.

[0004]

As the network equipment becomes more multifunctional and more sophisticated, the load on the processing section will increase, resulting in a larger amount of heat generation and more efficient heat dissipation.
At that time, if the housing of the network device is made large, the heat dissipation efficiency is improved, but it is against the demand for miniaturization. Conventional network devices have not always satisfied the demand for diversification of installation as well as improvement of heat dissipation efficiency.

Therefore, it is an exemplary object of the present invention to provide a mounting mechanism capable of improving heat dissipation of a network device and diversifying installation, and a network device having the mounting mechanism.

[0006]

In order to achieve the above object, an attachment mechanism according to one aspect of the present invention is an attachment mechanism for attaching a network device for assisting communication on a network by a communication device to a wall. And a heat dissipation member that engages with the housing of the network device to support the housing, and that dissipates heat from the network device, and the heat dissipation member that engages with the heat dissipation member and is engaged with the housing. A mounting member for mounting the member to the wall. Such a mounting mechanism contributes to downsizing because the heat dissipating member also has a heat dissipating function while diversifying the mounting.
Further, the above-described network device having such an attachment mechanism also exhibits the same operation.

The mounting portion may be made of a magnet, and the wall may be made of a material that can be coupled to the magnet. As a result, the network device can be easily installed at an arbitrary position on the wall without damaging the wall. The housing includes a first mounting portion for mounting the housing on the wall in a first posture, as a mounting portion engageable with a heat dissipation member, the housing on the wall, and the first mounting portion. You may have a 2nd attachment part for attaching in a 2nd posture different from a posture. As a result, it is possible to diversify the installation while responding to the taste of the user and the convenience of wiring. A convex portion may be formed on one of the mounting portion of the housing and the heat dissipation member, and a concave portion may be formed on the other side so that the convex portion can be separably fitted. This makes it possible to connect and disconnect the mounting portion and the heat dissipation member by a simple method, and in particular, if any of the plurality of mounting members is provided, the separable structure can be installed in various postures (for example, horizontal placement or vertical placement). (Arrangement) can be realized.

[0008] A network device as another aspect of the present invention is a network device for assisting communication on a network by a communication device, and a casing having a heat dissipation groove for radiating the network device, And a support member that has a convex portion that is engaged with and guided by the heat dissipation groove and that allows the network device to be installed on a table. According to such a network device, the heat dissipation groove has both a heat dissipation function and a positioning function.

The support member may have a horizontal portion which is horizontal to the table and is made of a heat conductive material. Thereby, the heat from the network device can be conducted to the tabletop. The support member may include a vertical portion that includes the convex portion, faces the heat radiation groove, and includes a heat radiation hole that communicates with the heat radiation groove. Thereby, the support member does not interfere with the heat dissipation effect of the housing while fixing the housing. The supporting member includes a first vertical portion having the convex portion, and a second vertical portion that cooperates with the first vertical portion to sandwich the network device.
The second vertical portion further has a leaf spring portion provided to face the convex portion, and the housing further has a concave portion into which the leaf spring portion can be fitted. However, the leaf spring portion may be configured to be able to press the housing against the convex portion. An elastic force is applied to the housing so that the leaf spring portion strengthens the engagement between the heat radiating groove portion and the convex portion, and the leaf spring portion fits into the concave portion, so that the housing is prevented from easily falling off the supporting member. be able to. When the network device is installed on the tabletop, the network device may extend vertically from the tabletop and have a plurality of terminals to which a plurality of communication devices can be connected. For such a so-called vertical type network device, the above-mentioned supporting member is particularly important in order to ensure stability when it is installed on a table.

Other objects and further features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

The housing 10 further has four pairs of mounting portions 32 to 38, as shown in FIG. The mounting portions 32 to 38 are not necessary for the stand 60 because they are used in another mounting method described later, but the stand 60 and one of the mounting methods described later can be selected, so that the mounting can be diversified. I am trying. Each pair of mounting parts 32 to 3
The intervals and sizes of 8 are equal. Mounting parts 32 and 38
Are parallel, the mounts 34 and 36 are parallel and orthogonal to the mounts 32 and 38. It should be noted that the present invention does not limit the number of each mounting portion to one pair. Each of the mounting portions 32 to 38 has a projection 40, as will be described later.

Positioned and fixed at 0. As in the present embodiment, when the network device 100 is made multifunctional and highly functional to increase the load on the processing unit (not shown) and the amount of heat generation increases, the heat dissipation mechanism becomes important. On the other hand, it is preferable that the housing 10 be as small as possible in order to reduce the size of the network device. According to the network device 100 of the present embodiment, since the heat dissipation groove 14 serves both as heat dissipation and positioning, the housing 10
The internal electronic circuits are protected from thermal damage by radiating heat without increasing the size of the.

Next, a mounting method according to another embodiment of the present invention will be described. As described above, this embodiment also uses the housing 10 in common, but instead of the stand 60,
The wall fitting 80 and the screw 90 are used. In addition, the housing 10
Uses the mounting portions 32 to 38 instead of using the heat dissipation groove 14 and the depression 24. In this embodiment,
The housing 10 is fixed in a desired posture on a wall, a partition, a shelf, or another substantially vertical installation place (in the present application, such installation place is simply referred to as a “wall”).
As described above, the network device 100 can be installed on a table or a wall, and the installation is diversified.

First, referring to FIG. 6 to FIG.
The mounting portions 32 to 38 of will be described in detail. here,
FIG. 6 is an external perspective view before the wall fitting 80 is attached to the housing 10. FIG. 7 is a sectional view taken along line AA of FIG. FIG. 8 is an external perspective view of the network device 100 in which the wall fitting 80 is attached to the housing 10. Figure 9
FIG. 9 is a sectional view taken along line BB of FIG. 8. Note that W in FIG. 9 is a wall.

As shown in FIG. 7, each mounting portion has a protrusion 40 and an insertion port 42. The protrusion 40 is formed on the inner surface of each mounting portion facing the housing 10 so as to project toward the housing 10. The protrusion 40 is a wall fitting 8 described later.
It has a function as a stopper that fits into the hole 82 of 0 and prevents the wall-mounting metal fitting 80 from falling out of the mounting portion. Further, since it can be separated from the hole 82, the wall-mounting metal fitting 80
To engage the desired one of the mounts 32-38. An engaging portion 81 of a wall fitting 80, which will be described later, is inserted into the insertion port 42.

The wall fitting 80 is made of, for example, stainless steel having high heat conductivity and rigidity, and as shown in FIG. 6, a pair of engaging portions 81, a pair of connecting portions 83, a base portion 84,
And an engaging portion 86.

The engaging portion 81 has a base portion 84 via a connecting portion 83.
In addition, it is connected to a position deeper than the base portion 84. Each of the engaging portions 81 has, for example, a shape in which a semicircle and a rectangle are combined, and has a circular hole 82 at the substantially center thereof. The engaging portion 81 is inserted into the insertion port 42 of the corresponding mounting portion, and the hole 82 engages with the protrusion 40 of the corresponding mounting portion. Therefore, the distance between the engaging portions 81 is equal to the distance between the mounting portions. It goes without saying that the engaging portion 81 may have a protrusion and the mounting portion may have a hole.

The connecting portion 83 is provided with a screw 9 when the wall fitting 80 is attached to the attaching portion as shown in FIG.
It is provided to secure a space 91 for accommodating the 0 head. The connecting portion 83 also has a function as a stopper that supports the corresponding mounting portion.

The base portion 84 has a pair of holes 85. Figure 9
The screws 90 are driven into the wall W through the holes 85, as shown in FIG. Further, it has a pair of screw holes 88 used in a modification of the present embodiment described later. A screw 98 for fixing a magnet 95 described later is inserted into the screw hole 88.

The engaging portion 86 is used in a modification of this embodiment described later and is connected to the base portion 84 in the same plane as the base portion 84. The same plane means that the other surface of the magnet 95 (that is, the surface facing the metal fitting 80) forms the same plane regardless of which of the three same magnets 95 described later is used for the engaging portion 86. This is because Therefore, by increasing the thickness of the specific magnet,
Therefore, even if a member similar to the connecting portion 83 is used and it is formed at a position recessed from the base portion 84, it is sufficient that the other surfaces of all the magnets 95 can form the same plane. The other surface of all the magnets 95 must form the same plane because the surface of the wall W is usually horizontal,
This is to maintain the levelness when mounting. Engaging part 8
6 has an exemplary chamfered rectangular shape, and has a screw hole 8
7 in the approximate center. The screw hole 87 has a screw hole 88.
Similarly, a screw 98 for fixing a magnet 95 described later.
Is inserted.

When the housing 10 is hung on the wall W, first, the wall fitting 80 is fixed at a desired position on the wall W through the two screws 90 and the holes 85. Next, the insertion ports 42 of the desired mounting portions 32 to 38 are inserted into the engaging portions 81, and the protrusions 40 are fitted into the holes 82. In FIGS. 8 and 9, the mounting portion 32 is selected. As a result, the housing 10 can be installed on the wall W in a desired posture. A desired position on the wall W and a desired posture of the housing 10 can be freely set by the user based on wiring, aesthetics and the like. Protrusion 40
The connection portion 83 supports the housing 10 even if the engagement between the hole 82 and the hole 82 is disengaged. Further, since the head of the screw 90 fits in the space 91, the screw 90 does not damage the back surface of the housing 10. Further, the wall fitting 80 is made of a material having a high thermal conductivity, and conducts heat from the heat dissipation groove 16 and other parts of the housing 10 to the wall W to protect the electronic circuit inside the housing from thermal destruction. Thus, the wall fitting 80 cooperates with the mounting portions 32 to 38 of the housing 10 to position, position and fix the housing 10, and further radiates the housing 10.

Next, a modified example of the present embodiment will be described with reference to FIGS. 6 and 10 to 12. This embodiment also uses the housing 10 and the wall fitting 80 in common, but instead of the screw 90, a magnet 95 is used. Also in this embodiment, the housing 10 is fixed to the wall W in a desired posture,
The wall W of this embodiment is made of a metal material such as steel that can fix the magnet. Here, FIG. 10 shows the magnet 9
5 is a sectional view of FIG. FIG. 11 shows that the housing 10 has a wall-mounting metal fitting 80.
And network device 1 with magnet 95 attached
It is an external appearance perspective view of 00. FIG. 12 is a sectional view taken along line CC of FIG. Further, in FIG. 6, the magnet 95 is attached to the metal fitting 80.
It shows the state before it is attached to.

The magnet 95, as shown in FIG.
It has central holes 96 and 97 in its approximate center. Central hole 96
As shown in FIG. 12, accommodates the head of a screw 98 that fixes the magnet 95 to the metal fitting 80. The central hole 97 has a diameter smaller than that of the central hole 96, and has a diameter that allows the screw portion of the screw 98 to pass but does not allow the head to pass.

When the case 10 is hung on the wall W, first, the magnet 95 is fixed to the screw holes 87 and 88 of the wall fitting 80 through the screw 98. Then, the wall fitting 80 is fixed to the desired position on the wall W by using the magnetic force of the magnet 95. Since the surfaces of all the magnets 90 facing the wall W form the same plane, it is convenient to maintain the levelness of the housing 10 and to firmly fix the housing 10.

Next, the desired mounting portion 32 is attached to the engaging portion 81.
38 to 38 are inserted, and the protrusion 40 is fitted into the hole 82. 11 and 12, the mounting portion 32
Is selected. As a result, the housing 10 can be installed on the wall W in a desired posture. A desired position on the wall W and a desired posture of the housing 10 can be freely set by the user based on wiring, aesthetics and the like. Even if the protrusion 40 and the hole 82 are disengaged from each other, the connecting portion 83 supports the housing 10. Further, since the screw portion of the screw 98 is accommodated in the space 91, the screw 98 does not damage the back surface of the housing 10. Further, the wall fitting 80 is made of a material having high thermal conductivity, and conducts heat from the heat dissipation groove 16 and other parts of the housing 10 to the wall W to protect the electronic circuit inside the housing from thermal destruction. In this way, the wall fitting 80 cooperates with the mounting portions 32 to 38 of the housing 10 to position, position and fix the housing 10, and further radiates heat from the housing 10.

The preferred embodiments of the present invention have been described above, but the present invention can be variously modified and changed within the scope of the gist thereof. For example, the type of the network device 100 is not limited to the switch.

[0038]

According to the attachment mechanism and the network device according to one aspect of the present invention, the attachment member also has a heat dissipation function while diversifying the attachment, so that the attachment function and the heat dissipation function are not separated. Contributes to miniaturization of network equipment. Further, according to the network device as another aspect of the present invention, since the heat dissipation groove has both the heat dissipation function and the positioning function, it contributes to downsizing of the network device rather than separating the mounting function and the heat dissipation function.
