Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a machine box installation component and communication equipment. Background Art

[0002] In the prior art, when a communication equipment box is installed on a rack, the box is fixed to two upright posts at the front end of the rack through the left and right hanging ears at the front end of the box. The disadvantage of this method is that when the box is deep and heavy, the rear end of the box is prone to droop. The drooping rear end of the box will occupy the installation space of other equipment and affect the spatial layout of the rack. Summary of the invention

[0003] The invention provides a machine box installation component and communication equipment, which are used to improve the problem of the tail of the machine box sagging after being mounted on a shelf.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A machine box mounting assembly provided by the present invention includes a mounting arm and a hanging ear, wherein the hanging ear includes a main body and a first plug-in portion, the main body is in a flat plate shape, and is used to fit and be fixed to the tail section of the side wall of the machine box; the main body includes a first surface and a second surface that are arranged opposite to each other, and the first surface is used to fit the side wall of the machine box; the first plug-in portion is connected to the bottom of the main body and extends in a direction away from the top of the main body; an end of the first plug-in portion away from the top of the main body is located on a side of the second surface away from the first surface;

[0006] The mounting arm includes a mounting arm body and a first plug-in slot, the mounting arm body is used to be fixed to the rear end of the rack, the first plug-in slot is fixed to the bottom of the mounting arm body and is located on the side of the mounting arm body facing the hanging ear; the first plug-in portion can be inserted into the first plug-in slot and is slidably connected to the first plug-in slot.

[0007] The tail sections of the arms on both sides of the machine box are connected to the rear end of the machine box by using the machine box mounting assembly provided by this embodiment, which can reduce or even avoid the situation that the tail of the machine box sags. Specifically, taking the connection of the side wall on one side of the machine box as an example, the hanging ear in the machine box mounting assembly is fixed to the tail section of the side wall of the machine box, and the first surface of the main body of the hanging ear is fitted with the tail section of the side wall, the mounting arm body is fixed to the rear end of the rack, and the mounting arm is extended toward the front end of the rack. Subsequently, the first plug-in portion of the hanging ear is inserted into the first plug-in slot and slidably connected with the first plug-in slot. The first plug-in slot can play a role in supporting the tail of the machine box, thereby reducing the possibility of the tail of the machine box sagging, and even avoiding the situation that the tail of the machine box sags.

[0008] In addition, the direction from the first plug-in portion to the second plug-in portion (mentioned later) is the first direction, the direction perpendicular to the first direction in the first surface is the second direction, and the direction perpendicular to the first direction and the second direction in the space is the third direction. The first plug-in portion is plate-shaped. Compared with the groove-shaped structure, the dimensions of the plate-shaped first plug-in portion in the first direction and the third direction are easier to control, so that the dimensions of the machine box installation component in the first direction (that is, the dimensions in the height direction of the machine box), and the dimensions of the machine box and the two hanging ears after the two side arms of the machine box are connected to the hanging ears in the third direction do not exceed the dimensions required in the art. For example, in a specific implementation, the dimension of the machine box in the third direction is 442mm, the dimension of the hanging ear in the third direction is 2.7mm, and the sum of the dimensions of the machine box and the two hanging ears in the third direction is 447.4mm, which is less than the 450mm required in the art, and the dimension of the mounting arm in the first direction is 43.6mm, which is also less than the dimensions required in the art.

[0009] Optionally, the hanging ear includes a second plug-in portion, which is connected to the top of the main body and opposite to the first plug-in portion; the second plug-in portion extends in a direction away from the bottom of the main body, and one end of the second plug-in portion away from the top of the main body is located on the side of the second surface away from the first surface; the mounting arm includes a second plug-in slot, which is fixed at the top of the mounting arm body and located on the side of the mounting arm body facing the hanging ear; the second plug-in portion can be inserted into the second plug-in slot and slidably connected with the second plug-in slot. In other words, the hanging ear and the mounting arm are both slidably connected at both ends of the top and the bottom, which makes it possible for the tail sections of the arms on both sides of the machine box to adopt the machine box mounting assembly provided by the present application. On the one hand, in one machine box mounting assembly, the connection and relative sliding reliability between the hanging ear and the mounting arm are stronger; on the other hand, the mounting arm can provide better support for the machine box, further reducing the possibility of sagging of the tail of the machine box.

[0010] Optionally, the thickness of the first plug-in portion and the second plug-in portion are both smaller than the thickness of the main body, so that after the two side arms of the case are connected to the hanging ears, the dimensions of the case and the two hanging ears in the third direction are more guaranteed.

[0011] Optionally, the main body includes a first plate body and a second plate body stacked and fixedly connected to the surface of the first plate body, the side surface of the first plate body facing away from the second plate body is the first surface, and the side surface of the second plate body facing away from the first plate body is the second surface; the first plug-in portion, the second plug-in portion and the second plate body are an integrally formed structure to facilitate the processing of the main body.

[0012] Optionally, the main body is an integrally formed sheet metal part;

[0013] The direction from the first plug-in portion to the second plug-in portion is the first direction, the direction in the first surface perpendicular to the first direction is the second direction, the main body includes a first end and a second end located in the second direction, the first plate body and the second plate body are integrally connected at the first end and fixedly connected at the second end.

[0014] Optionally, the main body is provided with at least one connection hole group, each of which includes a plurality of countersunk holes arranged at intervals, each of which includes a first hole section formed in the first plate body and a second hole section formed in the second plate body, and the second hole section is used to accommodate the head of the screw. In this way, it is convenient to arrange the countersunk hole, and the head of the screw can be accommodated in the second hole section, which can avoid the influence of the head of the screw on the size of the machine box mounting assembly in the third direction. It can also ensure smooth sliding between the hanging ear and the mounting arm.

[0015] Optionally, the main body includes three connection hole groups sequentially arranged along the second direction, wherein each connection hole group includes four countersunk holes arranged in a rectangular shape, and the size of the distribution area of ​​the connection hole group located in the middle in the second direction in the first direction is larger than the sizes of the distribution areas of the other two connection hole groups in the first direction;

[0016] The first plug-in portion includes two first sub-plug-in portions, and the second plug-in portion includes two second sub-plug-in portions. The two first sub-plug-in portions and the two second sub-plug-in portions are opposite to the two connection hole groups located on both sides in the second direction, and the projection of each sub-plug-in portion in the second direction overlaps with the projection of the distribution area of ​​the connection hole group in the middle in the second direction in the second direction. The two first sub-plug-in portions can be plugged into the first plug-in slot, and the two second sub-plug-in portions can be plugged into the second plug-in slot. In this solution, the layout of the connection hole group and the layout of each sub-plug-in portion are combined to minimize the size of the hanging ear in the first direction.

[0017] Optionally, the mounting arm body includes a head end and a tail end, the tail end is connected to at least one L-shaped bending structure, the L-shaped bending structure includes a first portion fixed to the mounting arm body and a second portion fixed to the first portion away from one end of the mounting arm body, the second portion extends toward the head end and is used to be inserted into the rear end of the rack; the tail end is also fixed with a connecting plate, the connecting plate and the first portion are located in the same plane, and are provided with a through hole for the connecting member to pass through. In this way, the mounting arm can be fixed to the rear column by a locking member, which can reduce the locking time and improve the installation efficiency; at the same time, the adjustment and setting of the position of the mounting arm at the rear end of the rack is also more convenient.

[0018] Optionally, a guide plate is provided at the head end, the guide plate is located at a side of the mounting arm body away from the first plug slot, and the distance between the guide plate and the mounting arm body gradually increases in a direction away from the tail end. The guide plate is used to guide the hanging ear when it slides into the mounting arm, so as to facilitate the sliding connection between the hanging ear and the mounting arm.

[0019] Optionally, the length of the mounting arm is adjustable, thereby making the machine box mounting assembly provided by this embodiment more versatile.

[0020] Optionally, the length of the plug slot is greater than the length of the corresponding plug portion, that is, the length of the first plug slot is greater than the length of the first plug portion, and the length of the second plug slot is greater than the length of the second plug portion.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-Figure 4 As shown, a machine box mounting assembly provided by an embodiment of the present application includes a mounting arm 1 and a hanging ear 2, wherein the hanging ear 2 includes a main body 21 and a first plug-in portion 22, the main body 21 is in a flat plate shape, and is used to fit and be fixed to the tail section 101 of the side wall of the machine box 100; the main body 21 includes a first surface 211 and a second surface 212 that are arranged opposite to each other, and the first surface 211 is used to fit with the side wall of the machine box 100; the first plug-in portion 22 is connected to the bottom of the main body 21 and extends in a direction away from the top of the main body 21; an end of the first plug-in portion 22 away from the top of the main body 21 is located on a side of the second surface 212 away from the first surface 211;

[0036] The mounting arm 1 includes a mounting arm body 11 and a first plug-in slot 12. The mounting arm body 11 is used to be fixed to the rear end of the rack 200. The first plug-in slot 12 is fixed to the bottom of the mounting arm body 11 and is located on the side of the mounting arm body 11 facing the hanging ear 2. The first plug-in portion 22 can be inserted into the first plug-in slot 12 and is slidably connected to the first plug-in slot 12.

[0037] The tail sections 101 of both side arms of the machine box 100 are connected to the rear end of the machine box 100 with the machine box installation assembly provided by this embodiment, which can reduce or even avoid the sagging of the tail of the machine box 100. Specifically, taking the connection of the side wall of one side of the machine box 100 as an example, the ear 2 in the machine box installation assembly is fixed to the tail section 101 of the side wall of the machine box 100, and the first surface 211 of the main body 21 of the ear 2 is fitted with the tail section 101 of the side wall, the mounting arm body 11 is fixed to the rear end of the frame 200, and the mounting arm 1 is extended toward the front end of the frame 200. Subsequently, the first plug-in portion 22 of the ear 2 is inserted into the first plug-in slot 12 and slidably connected with the first plug-in slot 12. The first plug-in slot 12 can play a role in supporting the tail of the machine box 100, thereby reducing the possibility of sagging of the tail of the machine box 100, and even avoiding the sagging of the tail of the machine box 100.

[0038] In addition, the direction from the first plug-in portion 22 to the second plug-in portion 23 (mentioned later) is the first direction a, the direction perpendicular to the first direction a in the first surface 211 is the second direction b, and the direction perpendicular to the first direction a and the second direction b in the space is the third direction c. The first plug-in portion 22 is plate-shaped. Compared with the groove-shaped structure, the dimensions of the plate-shaped first plug-in portion 22 in the first direction a and the third direction c are easier to control, so that the dimensions of the machine box installation assembly in the first direction a (that is, the dimensions in the height direction of the machine box 100), and the dimensions of the machine box 100 and the two hanging ears 2 after the two side arms of the machine box 100 are connected to the hanging ears 2 in the third direction c do not exceed the dimensions required in the art. For example, in a specific implementation, the size of the machine box 100 in the third direction c is 442 mm, the size of the ear 2 in the third direction c is 2.7 mm, and the sum of the sizes of the machine box 100 and the two ears 2 in the third direction c is 447.4 mm, which is smaller than the 450 mm required in the art, and the size of the mounting arm 1 in the first direction a is 43.6 mm, which is also smaller than the size required in the art.

[0039] It is easy to understand that the top and bottom of the main body 21 and the mounting arm body 11 are both in terms of the orientation when the machine box mounting assembly is correctly installed on the rack 200. That is to say, the top of the main body 21 is the end of the main body 21 close to the top of the rack 200, and the bottom of the main body 21 is the end of the main body 21 close to the bottom of the rack 200; the top of the mounting arm body 11 is the end of the mounting arm body 11 close to the top of the rack 200, and the bottom of the mounting arm body 11 is the end of the mounting arm body close to the bottom of the rack 200.

[0040] When the above-mentioned hanging ear 2 is specifically set, in an optional implementation, the hanging ear 2 includes a second plug-in portion 23, which is connected to the top of the main body 21 and is opposite to the first plug-in portion 22. The second plug-in portion 23 extends in a direction away from the bottom of the main body 21, and one end of the second plug-in portion 23 away from the top of the main body 21 is located on the side of the second surface 212 away from the first surface 211. The mounting arm 1 includes a second plug-in slot 13, which is fixed at the top of the mounting arm body 11 and is located on the side of the mounting arm body 11 facing the hanging ear 2; the second plug-in portion 23 can be inserted into the second plug-in slot 13 and is slidably connected to the second plug-in slot 13. That is to say, both the hanging ear 2 and the mounting arm 1 are slidably connected at both the top and bottom ends, so that when the tail sections 101 of the arms on both sides of the machine box 100 adopt the machine box mounting assembly provided by this embodiment, on the one hand, in one machine box mounting assembly, the connection and relative sliding reliability between the hanging ear 2 and the mounting arm 1 are stronger; on the other hand, the mounting arm 1 can provide better support for the machine box 100, further reducing the possibility of the tail of the machine box 100 sagging.

[0041] Exemplarily, the length of the plug-in slot is greater than the length of the corresponding plug-in portion, that is, the length of the first plug-in slot 12 is greater than the length of the first plug-in portion 22, and the length of the second plug-in slot 13 is greater than the length of the second plug-in portion 23. Thus, the machine box mounting assembly provided in this embodiment can be applicable to racks 200 of different depths, and has stronger versatility. Furthermore, both the first plug-in portion 22 and the second plug-in portion 23 can be in the shape of a strip extending along the first direction a, so as to increase the contact area with the corresponding plug-in slot while ensuring the dimensions in the first direction a and the third direction c, so that the sliding connection between the hanging ear 2 and the mounting arm 1 is more reliable. In an optional implementation, the first plug-in portion 22 and the second plug-in portion 23 are symmetrical structures, and the first plug-in slot 12 and the second plug-in slot 13 are also symmetrical structures.

[0042] Optionally, the two top corners of each plug-in portion away from the main body 21 can both be chamfered structures e, which can play a guiding role in the process of inserting each plug-in portion into the corresponding plug-in slot, thereby making it easier for each plug-in portion to be inserted into the corresponding plug-in slot.

[0043] In a specific implementation, the thickness of the first plug-in portion 22 and the second plug-in portion 23 are both smaller than the thickness of the main body 21, so that after the two side arms of the machine box 100 are connected to the hanging ears 2, the dimensions of the machine box 100 and the two hanging ears 2 in the third direction c are more guaranteed.

[0044] Furthermore, when the main body 21 is specifically arranged, Figure 5 and Figure 6 As shown, in an optional implementation, the main body 21 includes a first plate 213 and a second plate 214 stacked and fixedly connected to the surface of the first plate 213, wherein the surface of the first plate 213 facing away from the second plate 214 is the first surface 211, and the surface of the second plate 214 facing away from the first plate 213 is the second surface 212; the first plug-in portion 22, the second plug-in portion 23 and the second plate 214 are an integrally formed structure. Exemplarily, the first plug-in portion 22, the second plug-in portion 23 and the second plate 214 can be integrally formed from the same plate material with the same thickness.

[0045] Furthermore, in an optional implementation, the main body 21 is an integrally formed sheet metal part. Specifically, the main body 21 includes a first end 220 and a second end 230 located in the second direction b. The first plate 213 and the second plate 214 are integrally connected at the first end 220 and fixedly connected at the second end 230. For example, a plate is folded in half and then edge-pressed at the fold to obtain the first plate 213 and the second plate 214 stacked as described above, and one end of the edge-pressed edge is the first end 220. At the second end 230, the first plate 213 and the second plate 214 can be fixedly connected by rivets.

[0046] In an optional implementation, the main body 21 is provided with at least one connection hole group, each connection hole group is used to connect with a side wall of a machine box 100, so as to further improve the versatility of the machine box installation assembly provided by this embodiment. Specifically, each connection hole group includes a plurality of countersunk holes 241 arranged at intervals, each countersunk hole 241 includes a first hole section 2411 formed on the first plate body 213 and a second hole section 2412 formed on the second plate body 214, and the second hole section 2412 is used to accommodate the head of the screw 300. In this way, it is convenient to set the countersunk hole 241, and the head of the screw 300 can be accommodated in the second hole section 2412, which can avoid the influence of the head of the screw 300 on the size of the machine box installation assembly in the third direction c. It can also ensure smooth sliding between the hanging ear 2 and the mounting arm 1. Exemplarily, the screw 300 passes through the main body 21 and is locked to the machine box 100.

[0047] In a specific implementation, the main body 21 includes three connection hole groups arranged in sequence along the second direction b, wherein each connection hole group includes four countersunk holes 241 arranged in a rectangular shape, the size of the distribution area of ​​the connection hole group located in the middle in the second direction b in the first direction a is larger than the size of the distribution area of ​​the other two connection hole groups in the first direction a, and the size of the distribution area of ​​the two connection hole groups located on both sides in the second direction b in the first direction a is also different. That is, the spacing between adjacent countersunk holes 241 in each connection hole group is different, and the three connection hole groups are respectively used to connect machine boxes of different specifications. The first plug-in portion 22 includes two first sub-plug-in portions 221, and the second plug-in portion 23 includes two second sub-plug-in portions 231, and the two first sub-plug-in portions 221 and the two second sub-plug-in portions 231 are opposite to the two connection hole groups located on both sides in the second direction b. The projection of each sub-plug-in portion in the second direction b overlaps with the projection of the distribution area of ​​the connection hole group located in the middle of the second direction b in the second direction b. That is to say, in the first direction a, the two first sub-plug-in portions 221 are opposite to the two second sub-plug-in portions 231 one by one, and the distance between the connection point of the first sub-plug-in portion 221 and the main body 21 and the connection point of the corresponding second sub-plug-in portion 231 and the main body 21 is d1, and the size d2 of the distribution area of ​​the connection hole group located in the middle of the second direction b in the first direction, d1 is smaller than d2; both the two first sub-plug-in portions 221 can be plugged into the first plug-in slot 12, and both the two second sub-plug-in portions 231 can be plugged into the second plug-in slot 13. In this scheme, the layout of the connection hole group and the layout of each sub-plug-in portion can be combined to minimize the size of the hanging ear 2 in the first direction a. Exemplarily, a separation mark 215 can be provided between each adjacent two connection hole groups on the main body 21 to facilitate the installer to distinguish between the two adjacent connection hole groups.

[0048] Of course, in other implementations, the outline of the main body 21 may also be a rectangle, and each plug-in portion is connected to a corresponding edge of the main body 21 .

[0049] Furthermore, on the basis of the above-mentioned three connection hole groups, the main body 21 can also include another connection hole group. For example, the main body 21 can also include a connection hole group, which includes three countersunk holes 241 spaced apart in the second direction b. The three countersunk holes 241 are respectively located at the center of the distribution area of ​​the above-mentioned three connection hole groups, so as to make better use of the space on the main body 21 of the hanging ear 2 on the basis of expanding the versatility of the machine box installation assembly.

[0050] When the above-mentioned mounting arm 1 is specifically set, in an optional implementation, as Figure 7-Figure 11As shown, the mounting arm body 11 includes a head end 111 and a tail end 112, and the tail end 112 is connected to at least one L-shaped bending structure 14, and the L-shaped bending structure 14 includes a first portion 141 fixed to the mounting arm body 11 and a second portion 142 fixed to the first portion 141 and away from one end of the mounting arm body 11, and the second portion 142 extends toward the head end 111 and is used to be inserted into the rear end of the rack 200; the tail end 112 is also fixed with a connecting plate 15, and the connecting plate 15 and the first portion 141 are located in the same plane, and a through hole 151 is provided for the connecting member to pass through. Exemplarily, the connecting plate 15 is provided with the above-mentioned through hole 151, and the through hole 151 is an oblong hole extending along the third direction c. In this way, the fixing of the mounting arm 1 on the rear column 201 can be achieved by a locking member, which can reduce the locking time and improve the installation efficiency; at the same time, the adjustment and setting of the position of the mounting arm 1 at the rear end of the rack 200 is also more convenient.

[0051] Furthermore, two top corners of the second portion 142 away from the first portion 141 may be chamfered structures f to facilitate alignment with corresponding mounting holes at the rear end of the rack 200 .

[0052] In a specific implementation, the tail end 112 of the mounting arm body 11 is connected to an L-shaped bending structure 14. In another specific implementation, the tail end 112 of the mounting arm body 11 is connected to two L-shaped bending structures 14, the two L-shaped bending structures 14 are arranged in sequence along the first direction a, and along the first direction a, the connecting plate 15 is located between the two L-shaped bending structures 14.

[0053] In an optional implementation, a guide plate 16 is provided at the head end 111 of the mounting arm body 11, and the guide plate 16 is located at a side of the mounting arm body 11 away from the first plug slot 12, and the distance between the guide plate 16 and the mounting arm body 11 gradually increases along the direction away from the tail end 112. In other words, the guide plate 16 is arranged obliquely relative to the mounting arm body 11 to form an inclined surface for providing a guide for the sliding in of the hanging ear 2, so that the guide plate 16 is used to play a guiding role in the process of the hanging ear 2 sliding into the mounting arm 1, so as to facilitate the sliding connection between the hanging ear 2 and the mounting arm 1.

[0054] Specifically, the rear end 112 of the mounting arm body 11 may be provided with a protrusion 17 facing the side of the hanging ear 2 , and the protrusion 17 is used to limit the extreme position of the hanging ear 2 when sliding along the mounting arm 1 to prevent the hanging ear 2 from sliding out of the mounting arm 1 .

[0055] Exemplarily, the mounting arm 1 may be an integrally formed structure.

[0056] In an optional implementation, the length of the mounting arm 1 is adjustable, so that the universality of the machine box mounting assembly provided by this embodiment is stronger. Specifically, the mounting arm 1 may include two sub-mounting arms connected in a sliding manner, and the two sub-mounting arms can slide relative to each other in the second direction b, so that the length of the mounting arm 1 is adjustable.

[0057] The machine box installation assembly provided in this embodiment has a simple structure, low cost, good strength and quality, and is easy for users to install and use.

[0058] like Figure 8 As shown, a communication device provided in this embodiment includes a rack 200, a box 100 and the above-mentioned box mounting assembly, wherein the tail of at least one side arm of the box 200 is mounted on the rear end of the rack through the above-mentioned box mounting assembly. Therefore, the possibility of at least one side tail of the box 200 sagging can be reduced, thereby reducing the possibility of the entire tail of the box 200 sagging.

[0059] Exemplarily, the rack 200 includes a front-end frame 202 and a rear-end frame, the number of the machine box 100 is at least one, each side wall of the machine box 100 corresponds to at least one machine box mounting assembly, the front end of each machine box 100 is fixed to the front-end frame 202, the mounting arm 1 in each machine box mounting assembly is fixed to the rear-end frame and extends in the direction of the front-end frame 202, and each plug-in portion is inserted into the corresponding plug-in slot. In other words, the first plug-in portion is inserted into the first plug-in slot, and the second plug-in portion is inserted into the second plug-in slot. In this solution, at least one of the above-mentioned machine box mounting assemblies is used in the tail sections 101 of the arms on both sides of the machine box 100 to realize the connection between the tail of the machine box 100 and the rear end of the rack 200, which can reduce or even avoid the drooping of the tail of the machine box 100.

[0060] In addition, the first plug-in portion 22 is plate-shaped. Compared with the groove-shaped structure, the dimensions of the plate-shaped first plug-in portion 22 in the first direction a and the third direction c are easier to control, so that the dimensions of the machine box mounting assembly in the first direction a (that is, the dimensions in the height direction of the machine box 100), and the sum of the dimensions of the machine box 100 and the two hanging ears 2 in the third direction c after the two side arms of the machine box 100 are connected to the hanging ears 2 do not exceed the dimensions required in the art.

[0061] It is worth noting that, when a side wall of the machine box 100 corresponds to a plurality of machine box mounting components, the plurality of machine box mounting components can be arranged in sequence along the first direction.

[0062] Exemplarily, the front frame 202 may include two front columns spaced apart along the third direction c, the rear frame may include two rear columns 201 spaced apart along the third direction c, and the mounting arm 1 is fixedly connected to the corresponding rear columns 201. For example, the rear column 201 is provided with a plurality of mounting holes penetrating along the second direction b, the second portion 142 of the L-shaped bending structure 14 of the mounting arm 1 is inserted into the corresponding mounting hole, a screw passes through the through hole 151 on the connecting plate 15 and another corresponding mounting hole on the rear column 201 and is threadedly connected with a nut, thereby achieving the fixing of the mounting arm 1 on the rear column 201.

[0063] It is worth noting that the communication device mentioned in this embodiment may be a device such as a switch or a server including a box 100 and a rack 200. The box 100 may be installed with a main control module and / or a communication module.

[0064] The following is a brief introduction to an assembly method of a communication device provided in this embodiment. The assembly method of the communication device includes:

[0065] Step 1: Lock the two mounting ears 2 to the corresponding holes of the rear section 101 of the side walls of the case 100, as shown in FIG. Figure 4 As shown;

[0066] Step 2: Lock the two mounting arms 1 onto the two rear columns 201 of the rack 200 respectively;

[0067] Step 3: Align the case 100 with the hanging ears 2 locked at the two side arms with the two mounting arms 1 locked to the rear pillar 201 in step 2, so that the two hanging ears 2 are slidably connected with the corresponding mounting arms 1 respectively;

[0068] Step 4: Fix the front end of the housing 100 to the front frame 202 of the rack 200 .

[0069] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
