Description

Network device mounting mechanism

Technical field

The present invention relates to an attachment mechanism for attaching network devices such as hubs, routers, and switches to objects such as desks, stands, partitions, and walls.

 Technology background

 With the spread of LAN (Local Area Network) ^ WAN (Wide Area Network) in recent years, many personal computers (hereinafter referred to as “PCs”), network devices such as hubs, switches, routers, etc. (Hubs are sometimes called “agents.”) Are connected to the network and its subnets, and information is shared and transmitted frequently.

 Recently, diversification of the installation of network devices according to various usage patterns and installation patterns of users has been demanded. Specifically, conventional network equipment is generally horizontal and has been placed horizontally on a desktop, but the horizontal desktop requires a large installation space, and effective use of the installation space has been required.

 However, it was not possible to use a general-purpose rack or the like that is attached to a wall or the like and stores small items as an attachment mechanism for network equipment. This is because cables for connecting a large number of communication devices are connected to network equipment, and cables are scattered in general-purpose racks, leading to disconnections. If the cable is a single optical fiber cable, it will be easily broken unless it has a certain curvature or more.

Thus, an exemplary object of the present invention is to provide an attachment mechanism for bundling cables while effectively utilizing an installation space in which network devices are installed. DISCLOSURE OF THE INVENTION In order to achieve the above object, an attachment mechanism according to one aspect of the present invention includes a network which is connectable to a cable connected to a communication device, and which assists communication on the network by the communication device. An attachment mechanism for attaching a device to a target object at a predetermined angle with respect to a horizontal direction, the support mechanism supporting a housing of the network device, a storage portion capable of storing the cable, And an engaging portion connectable to the object. Such an attachment mechanism can attach a network device to the top plate of an object such as a desk having a top plate arranged in a substantially horizontal direction, for example, at 90 degrees, If there is extra space below, it can be used effectively. Further, the storage section can store the cable and prevent the cable from being scattered around the target section. In this case, the engaging portion may have, for example, a substantially C-shape such that the engaging portion engages with an edge of the top plate and arranges the support portion inside the top plate.

 The housing has a first surface and a second surface having an area smaller than the first surface, and the support unit supports the network device via the second surface, The housing may extend in a vertical direction while being supported by the support portion, and may have a plurality of terminals to which a plurality of communication devices can be connected. As described above, the present invention is particularly effective for effectively utilizing the installation space of the vertical network device. The attachment mechanism may further include a binding member that bundles the cable, and the storage unit may include a connection unit with which the binding member is engaged to bundle the cable on the storage unit. . For example, the bundle member is made of a tie wrap. The bundling member can secure the cable and maintain a constant radius of curvature of the cable if necessary.

The network device may further include a drawer mechanism that is relatively movable with respect to the support unit and that is capable of mounting and removing the network device from the support unit. This makes it possible to easily install and replace the network device by using the drawer mechanism, even if the engaging portion is provided behind the object. The support unit includes a drawer that changes the area of the support unit so that the number of supportable network devices can be changed. It may have a structure. Thus, a desired number of network devices can be mounted on the support. The drawer mechanism may have a handle. Such a handle facilitates movement of the drawer mechanism.

 The attachment mechanism is capable of accommodating a plurality of network devices, is relatively movable to the support unit, and further includes a drawer mechanism capable of mounting and removing the plurality of network devices independently from the support unit. May be. As a result, only the desired network device can be attached and replaced without affecting other network devices and communication devices connected thereto. The attachment mechanism may include a coupling portion detachably connectable to another attachment mechanism to accommodate a plurality of network devices. Thus, each mounting mechanism only needs to be able to store at least one network device, and when another network device needs to be installed, another mounting mechanism may be connected. In this case, the engaging portion of the other attachment mechanism is not necessarily required because it is not directly connected to the object.

 The relative angle between the support part and the engagement part may be displaceable. Such an angle can be set two-dimensionally or three-dimensionally. By adjusting the relative angle between the support portion and the engagement portion according to the shape of the installation space, the effective use of the installation space can be further promoted. The support unit may include a heat radiating unit that radiates heat of the network device. Such a mounting mechanism contributes to miniaturization because the supporting portion also has a heat radiation function. The support may include a magnet for holding the housing of the network. For example, the type of network device to be mounted and the manufacturer may be limited, for example, the screw hole must be in a predetermined position.However, using a magnet makes it easy to use a network device of any shape. High versatility because it can be supported.

The support section includes a first mounting section for mounting the housing in a first attitude, and a second mounting section for mounting the housing in a second attitude different from the first attitude. May be included. This makes it possible to diversify the installation while responding to user preferences and wiring convenience. The attachment mechanism may be formed by bending a single top plate. Thus, the mounting mechanism can be manufactured by a simple method. The support portion may be relatively movable with respect to the engagement portion. Thereby, for example, even if the engagement portion is provided in the back of the object, the installation and replacement of the network device can be easily performed by pulling out the support portion. The support section has a handle for moving the support section with respect to the engagement section. Such a handle facilitates movement of the support. Alternatively, the engagement portion may movably engage the object. Thereby, for example, even if the engaging portion is provided in the back of the object, the installation and replacement of the network device can be easily performed by pulling out the engaging portion. The relative angle between the engaging portion and the object may be displaceable. Such an angle can be set two-dimensionally or three-dimensionally. By adjusting the relative angle between the support portion and the engaging portion in accordance with the shape of the installation space, the effective use of the installation space can be further promoted.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an attachment 200 according to an embodiment of the present invention will be described with reference to the accompanying drawings. Here, FIG. 1 is a schematic perspective view showing a state in which the attachment 200 is attaching the network device 100 to the desk 1.

 The network device 100 is a network device that can be connected to a cable connected to a communication device such as a personal computer (not shown) and assists communication on the network by the communication device. The network device 100 is a network of hubs, switches, routers, other concentrators, reverters, bridges, gateway devices, servers, wireless repeaters (for example, access points that are wireless LAN relay devices). Broadly includes equipment.

The network device 100 of the present embodiment is configured as, for example, a staple hub. Stackable hub is different from cascade connection (multi-stage connection). By connecting hubs with a dedicated interface, multiple hubs can be used as one hub. For Ethernet, “10M hubs have 4 stages”,

Although there is a cascade rule of “100M hubs have two levels”, additional ports are required to expand the network. In some cases, it may be desirable to connect a hub beyond this limit, and in such a case, a statable hub is preferred.

 As shown in FIGS. 1 and 4, the network device 100 has a front face 102, a back face 104, a bottom face 106, and a left face 100 in a housing 101 having a substantially rectangular parallelepiped shape. 8 Here, FIG. 4 is a schematic perspective view showing the relationship between network device 100 and metal fittings 80.

 As shown in FIG. 1, the network device 100 has stack ports 112 and 114, a switch 116, and LEDs 118 and 120 on the front surface 102. Have. Stack ports 1 1 2 and 1 1 4 are ports required for stack connection, and cables 13 0 for connecting to other hubs are inserted. Switch 1 16 is a start switch of the main body. LED 118 displays the status of the network, and LED 120 displays the status of the hub itself.

 As shown in Fig. 4, the network device 100 has a 100BASE-TX port 122 on the rear surface 104, an MD I / MD I-X switching switch 124, and a power supply cable. 1 Bull 1 2 6 1 0 0 BA SE — TX ports 1 2 2 are vertically arranged in this embodiment. For example, these are connectors for connecting a UTP (not shown) connected to an external device such as an Ethernet hub. is there. 1 0 0 BA S E-TX port 1 2 2 is full-duplex (full-duplex) / Ha1 f-dup1 ex (half-duplex). Operate in the appropriate mode according to MD I ZMD I — X switch 1 2 4 is for 100 BASE — Uses TX port 122 as a cascade connection port Normal MD I — To set whether to use as X port It is a switch.

The bottom surface 106 of the housing 101 has the smallest area among the surfaces of the housing 101, and the bottom surface 106 is used for a support portion 210 of a mounting device 200 described later. It is supported by the horizontal section 2 1 4. As described above, the bottom surface 106 of the network device 100 having the smallest installation area easily fits in the space 4 below the top plate 2 of the desk 1, so that the vertical network The present invention is particularly effective for effectively utilizing the installation space of the connection device 100.

 As shown in FIG. 4, the network device 100 has four pairs of mounting portions 132 to 138 described later on a left side surface 108. The spacing and size of the mounting portions 13 2 to 13 38 of each pair are equal. Attachments 1332 and 1338 are parallel, and attachments 1434 and 1336 are parallel and orthogonal to attachments 1332 and 1338. 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 132 to 138 has a projection 140 and an insertion port 142 as described later.

 If the network device 100 is a media converter, the cable 130 becomes an optical fiber cable. Media converters convert signals on different media such as UTP and optical cables. Media converters include, for example, 100 BASE—TX port, link test switch, LED to confirm settings, communication mode switch, MDI / Μ Ό I—X switch, 100 BASE—FX Including ports, DC jacks, etc. If the cable 130 is an optical fiber-to-cable, it will be easily broken unless a predetermined curvature is maintained.

 Hereinafter, a mounting tool 200 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. Here, FIG. 2 (a) is a front view of the mounting tool 200, and FIG. 2 (b) is a left side view of the mounting tool 200. FIG. 3 is a partial schematic perspective view showing a tie wrap fitted into a notch of the mounting tool 200.

 For example, as shown in FIG. 1, the mounting device 200 is fixed to the side 2a of the top plate 2 of the desk 1, and the network device 100 is fixed to the desk 1 in a predetermined direction with respect to the horizontal direction. It has the function of mounting at an angle (90 ° in Fig. 1). The desk 1 has a top plate 2 projecting to the side, and forms a space 4 below the projecting portion. In the present embodiment, the mounting tool 200 aims to effectively use the space 4. The mounting tool 200 has a support part 210, a storage part 220, and an engagement part 230. The mounting device 200 of the present embodiment is configured by bending a single metal top plate. Thus, the mounting device 200 can be easily manufactured.

The support unit 210 supports the housing 101 of the network device 100. Support 2 10 has a vertical portion 2 12, a horizontal portion 2 14, and a pair of bent portions 2 16. The vertical part 212 supports the left side surface 108 of the network device 100. In some embodiments, the vertical portion 212 also has a heat dissipation function for the network device 100. The vertical portion 2 12 has a pair of holes 2 13 into which a bolt 290 described later is fitted. Actually, the number of pairs of holes 2 13 is not one, and there are holes corresponding to the mounting portions 13 4 to 1 38 described later, but these are shown in FIG. 2 (a) for convenience of drawing. Are omitted in.

 The height of the vertical portion 211 is set higher than the height of the network device 100. The width W of the horizontal portion 214 is set longer than the width of the network device 100. In one embodiment, the width W of the horizontal portion 214 is set to be at least twice the width of the network device 100 in order to accommodate two or more network devices 100. Thus, the support portion 210 can support two stat-able bull hubs connected in a stack. In the present embodiment, the bent portion 2 16 and the bent portion 2 26 have the same length 3 ZL.

The storage section 220 can store the cable 130. The storage section 130 stores the cable 130 to prevent the cable 130 from being scattered. The storage section 220 has a vertical section 222, a horizontal section 222, and a bent section 222. The height H ₂ of the vertical portion 2 2 2 is set to a length that can accommodate the cable 130. Since the height H ₃ of the bent portion 2 2 6 is shorter than the height H _2, a gap 2 2 7 is formed between the horizontal portion 2 2 4 and in fold bend 2 2 6. As a result, the cable 130 can be inserted into the horizontal portion 224 via the gap 227, and can be taken out from the horizontal portion 224 via the gap 227. If the height H ₃ of the bent part 2 26 is the same length as the height H ₂ , it is necessary to insert the cable 130 from one end of the cable 130 into the storage part 220, improving workability .

As shown in FIG. 3, the storage portion 220 has a cut-out portion for bundling the cable 130 on the horizontal portion 222 with the bundled member 240 binding the cable 130 in engagement. It has 2 2 8 For example, the binding member 240 is made of a tie wrap. This makes it possible to prevent the cable 130 from scattering. Further, the bundled member 240 fixes the cable 130, and for example, the cable 130 is an optical fiber cable. With this, a constant radius of curvature of the cable 130 can be maintained. Thereby, it is possible to prevent the cable 130 from being damaged. If necessary, a plurality of cutouts 228 may be provided in the direction of the width W, and different types of cables may be separately bundled together with the bundled member 240.

The engaging portion 230 is fixed to an edge of the top plate 2. The engaging portion 230 of the present embodiment has a substantially C-shape such that the supporting portion 210 is arranged inside the top plate 2 (that is, in the space 4). It has a vertical portion 234 and a bent portion 236. The horizontal part 2 32 and the bent part 2 36 have a width W, and the height H ₄ of the vertical part 234 is slightly higher than the height of the top plate 2 of the desk 1. The bent portion 236 has a pair of holes 237 into which the metal fitting 250 is inserted. The metal fitting 250 has a plate-mounted bolt 252, a nut 255, and a wing nut 256. The countersunk bolts 25 2 abut the lower surface of the top plate 2 of the desk 1 to fix the engaging portions 230 to the top plate 2. The height of the countersunk bolts 25 is adjustable.

 The mounting tool 200 of this embodiment further uses a metal fitting 280, a bolt 290, and a nut 291. First, with reference to FIGS. 4 to 6, the mounting portions 1332 to 1338 of the housing 101 will be described. Here, FIG. 4 is an external perspective view before the metal fitting 280 is attached to the housing 101. FIG. 5 is a sectional view taken along line AA of FIG. FIG. 6 is an external perspective view of the network device 100 in which the metal fitting 280 is attached to the housing 101. FIG. FIG. 7 is a sectional view taken along the line BB of FIG.

As shown in FIG. 5, each mounting portion has a projection 140 and an insertion port 142. The projection 140 is formed on the inner surface of each mounting portion facing the housing 101 so as to protrude toward the housing 101. The projection 140 fits into a hole 282 of a metal fitting 280 described later, and has a function as a stopper that prevents the metal fitting 280 from falling off from a corresponding mounting portion. Also, since it is separable from the hole 282, the metal fitting 280 can be engaged with a desired mounting portion of the mounting portions 132 to 138. An engagement portion 281 of a metal fitting 280 described later is inserted into the insertion port 144. The metal fitting 280 is made of, for example, stainless steel having high thermal conductivity and rigidity, and as shown in FIG. 4, a pair of engaging portions 281, a pair of connecting portions 283, and a base 280. 4 and an engaging portion 286. The engagement portion 281 is connected to the base 284 via the connection portion 283 at a position deeper than the base 284. Each engaging portion 281 has, for example, a shape in which a semicircle is combined with a rectangle, and has a circular hole 282 at substantially the center thereof. The engaging portion 281 is inserted into the insertion port 144 of the corresponding mounting portion, and the hole 282 is engaged with the projection 140 of the corresponding mounting portion. Therefore, the interval between the engaging portions 281 is equal to the interval between the mounting portions. Needless to say, the engaging portion 281 may have a projection and the mounting portion may have a hole.

 The connecting portion 283 is provided to secure a space S for accommodating the head of the bolt 290 when the metal fitting 280 is attached to the attaching portion as shown in FIG. The connecting portion 283 also has a function as a stopper for supporting the corresponding mounting portion. The bolt 290 engages the nut 291. The base 284 has a pair of holes 285. As shown in FIG. 7, the bolt 290 fits into the hole 2 13 of the vertical portion 2 12 of the support portion 210 via each hole 285. Further, it has a pair of bolt holes 288 used in a modified example of the present embodiment described later. A bolt 298 for fixing a magnet 295 described later is inserted into the bolt hole 288.

 The engaging portion 286 is used in a modification of the present embodiment described later, and is connected to the base 284 on the same plane as the base 284. The same plane is used even if any one of the three identical magnets 295 described later is used for the engaging portion 286, so that the other surface of the magnet 295 (that is, the metal fitting 280 is opposed). This is to make the same plane form the same plane. Therefore, by increasing the thickness of the specific magnet, the engaging portion 286 is formed from the base 284 to a portion deep from the base 284 using a member similar to the connecting portion 283. However, it is only necessary that the other surfaces of all the magnets 295 form the same plane. The other surface of all magnets 295 must form the same plane because the surface of the vertical part 212 is horizontal, so that the horizontality is maintained when the housing 101 is mounted. That's because. The engaging portion 286 has, for example, a chamfered rectangular shape, and has a bolt hole 287 at substantially the center thereof. A bolt 298 for fixing a magnet 295 to be described later is inserted into the bolt hole 287 similarly to the bolt hole 288.

When attaching the housing 101 to the vertical part 2 1 2 of the support part 210, first install two bolts 290 and a nut 291 in the hole 213 of the vertical part 212. And gold through holes 2 8 5 Fix fixture 2 80. Next, the engaging portion 281 is inserted into the insertion port 144 of the desired mounting portion 132 to 138, and the projection 140 is fitted into the hole 282. In FIGS. 6 and 7, the mounting portion 132 is selected. As a result, the housing 101 can be installed in a desired posture on the vertical portion 212 of the support portion 210.

 As described above, if a mounting portion other than the mounting portion 13 2 is selected, the position of the hole 2 13 changes, but for convenience of drawing, such a hole is omitted in FIG. 2 (a). In other words, the user can freely set the position and orientation of the casing 101 with respect to the vertical portion 212 based on wiring, aesthetics, and the like. That is, in one embodiment, the network device 100 is supported only by the vertical portion 212 and not by the horizontal portion 214. Of course, the present invention includes a case where the network device 100 is supported only by the horizontal portion 214 and not supported by the vertical portion 212.

 Even when the projection 140 and the hole 282 are disengaged from each other, the connecting portion 283 supports the housing 101. Also, since the head of the bolt 290 fits in the space S, the back of the housing 101 is not damaged by the bolt 290. Further, the metal fitting 280 is made of a material having high thermal conductivity, and conducts heat from the housing 101 to the vertical portion 212 to protect an electronic circuit inside the housing from thermal destruction. In this way, the metal fitting 280 cooperates with the mounting portions 132 to 1338 of the housing 101 to position, determine the posture, and fix the housing 101. Heat dissipation.

 Next, a modified example of the present embodiment will be described with reference to FIGS. 8 to 10. FIG. In this embodiment, a magnet 295 is used instead of the bolt 290, which is a force that commonly uses the housing 101 and the metal fitting 280. Also in the present embodiment, the housing 101 is fixed to the vertical portion 212, but the mounting tool 200 of the present embodiment is made of a metal material such as steel which can fix a magnet. Here, FIG. 8 is a cross-sectional view of the magnet 295. FIG. 9 is an external perspective view of a network device 100 in which a metal fitting 280 and a magnet 295 are attached to a housing 101. FIG. FIG. 10 is a sectional view taken along the line CC of FIG. FIG. 6 shows a state before the magnet 295 is attached to the metal fitting 280.

As shown in Fig. 8, the magnet 295 has a central hole 296 Have in the center. As shown in FIG. 10, the central hole 296 accommodates a head of a bolt 298 for fixing the magnet 295 to the metal fitting 280. The central hole 297 has a smaller diameter than the central hole 296, and has a diameter that allows the bolt portion of the bolt 298 to pass but does not allow the head to pass. Bolt 298 engages nut 299 via base 284.

 When attaching the housing 101 to the vertical part 212, first attach the magnet 295 to the bolt hole 287 of the metal fitting 280 via the bolt 298 and the nut 299. Fix to 2 8 8. Next, the metal fitting 280 is fixed to a desired position of the vertical part 212 by using the magnetic force of the magnet 295. However, for stable support, it is preferable that the bottom surface 106 of the housing is located at a position where it comes into contact with the support portion 210. Since the surface where all the magnets 2 95 face the vertical portion 2 12 forms the same plane, it is convenient to maintain the horizontality of the housing 101 and firmly fix it. In this embodiment, the holes 2 13 of the vertical portions 2 12 are not used.

 Next, the insertion holes 142 of the desired mounting portions 132 to 138 are inserted into the engaging portions 281, and the projections 140 are fitted into the holes 282. In FIGS. 9 and 10, the mounting portion 132 is selected. As a result, the housing 101 can be installed on the vertical portion 212 with a desired posture. The desired position of the vertical portion 212 and the desired posture of the housing 101 can be freely set by the user based on wiring, aesthetics, and the like. Even when the projection 140 and the hole 282 are disengaged from each other, the connection portion 283 supports the housing 101. Also, the nut 299 of the bolt 298 fits in the space S. Further, the metal fitting 280 is made of a material having high thermal conductivity, and conducts heat from the casing 101 to the vertical portion 212 to protect an electronic circuit inside the casing from thermal destruction. In this way, the metal fitting 280 cooperates with the mounting portions 132 to 1338 of the housing 101 to position, determine the posture, and fix the housing 101, and further, Dissipates heat.

Hereinafter, another embodiment of the present invention will be described with reference to FIG. Here, FIG. 11 is a schematic perspective view showing a drawer mechanism 300 as an embodiment of the present invention. In this embodiment, the network device 100 can be pulled out from the horizontal portion 214. The drawer mechanism 300 has a base 310 fixed inside the support 210, a drawer 320, and a handle 330 fixed to the front of the drawer 320. The base 310 has a U-shaped cross section, and has a groove 3112 extending in the K direction. The drawer 320 accommodates the network device 100, has a substantially rectangular parallelepiped shape, and has a convex portion 322 extending on the outer side surface in the K direction. The protrusions 3 2 2 fit into the grooves 3 1 2 and can slide along the grooves 3 1 2. Further, the side surface 324 of the drawer 320 may have the same height as the vertical portion 212 of the support portion 200 if necessary. Thus, the left side surface 108 of the network device 100 can be fixed to the side surface 324. The movement of the drawer 320 can be performed via the handle 330.

 As a result, the network device 100 can move relatively to the support portion 210 while being placed on the drawer 320. Therefore, even if the support unit 210 is provided at the back of the desk 1, by pulling out the drawer 320 from the support unit 210, mounting, replacement, and removal of the network device 100 can be performed. It will be easier. The mechanism for restricting the amount of the drawer 320 pulled out so that the drawer 3200 does not fall out of the base 330 can use any structure known in the art, and thus detailed description is omitted here. I do.

 Hereinafter, another embodiment of the present invention will be described with reference to FIG. Here, FIG. 12 is a schematic cross-sectional view showing a mounting device 200A having a support portion 21OA as another embodiment of the present invention.
