Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a housing mounting assembly and communication equipment. Background Technology

[0002] In existing technologies, the communication equipment enclosure is mounted on a rack by using left and right mounting lugs on the front side of the enclosure to fix it to two uprights at the front of the rack. A drawback of this method is that when the enclosure is deep or heavy, the rear end of the enclosure tends to sag. This sagging rear end occupies installation space for other equipment and affects the rack's spatial layout. Summary of the Invention

[0003] This invention provides a chassis mounting assembly and communication device to improve the problem of the chassis drooping after being mounted on a rack.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] The present invention provides a chassis mounting assembly including a mounting arm and a hook, wherein the hook includes a main body and a first insertion part, the main body is flat and used to fit and fix to the tail section of the side wall of the chassis; the main body includes a first surface and a second surface disposed opposite to each other, the first surface being used to fit against the side wall of the chassis; the first insertion part is connected to the bottom of the main body and extends in a direction away from the top of the main body; one end of the first insertion part away from the top of the main body is located on the side of the second surface away from the first surface;

[0006] The mounting arm includes a mounting arm body and a first insertion slot. The mounting arm body is used to fix to the rear end of the frame. The first insertion 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 insertion part can be inserted into the first insertion slot and is slidably connected with the first insertion slot.

[0007] The tail sections of both arms of the chassis utilize the chassis mounting assembly provided in this embodiment to connect the tail section of the chassis to the rear end of the frame, thereby reducing or even preventing the tail section of the chassis from sagging. Specifically, taking the connection of one side wall of the chassis as an example, the mounting lug in the chassis mounting assembly is fixed to the tail section of the side wall of the chassis, and the first surface of the main body of the mounting lug is made to fit against the tail section of the side wall. The mounting arm body is fixed to the rear end of the frame, and the mounting arm extends towards the front end of the frame. Subsequently, the first insertion part of the mounting lug is inserted into the first insertion slot and slidably connected with the first insertion slot. The first insertion slot can support the tail section of the chassis, thereby reducing the possibility of the tail section sagging, or even preventing the tail section of the chassis from sagging.

[0008] Furthermore, the direction pointing from the first insertion part to the second insertion part (mentioned later) is defined as the first direction, the direction perpendicular to the first direction within the first surface is defined as the second direction, and the direction perpendicular to both the first and second directions within the space is defined as the third direction. The first insertion part is plate-shaped. Compared to a groove-shaped structure, the dimensions of the plate-shaped first insertion part are easier to control in the first and third directions, ensuring that the dimensions of the chassis mounting assembly in the first direction (i.e., the dimensions in the chassis height direction), and the dimensions of the chassis and the two mounting ears connected to the side arms in the third direction, all do not exceed the dimensions required in this field. For example, in one specific implementation, the dimension of the chassis in the third direction is 442 mm, the dimension of the mounting ears in the third direction is 2.7 mm, and the sum of the dimensions of the chassis and the two mounting ears in the third direction is 447.4 mm, which is less than the required 450 mm in this field. The dimension of the mounting arm in the first direction is 43.6 mm, which is also less than the required dimension in this field.

[0009] Optionally, the hanging ear includes a second insertion portion connected to the top of the main body and opposite to the first insertion portion; the second insertion portion extends away from the bottom of the main body, and one end of the second insertion 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 insertion groove fixed to the top of the mounting arm body and located on the side of the mounting arm body facing the hanging ear; the second insertion portion can be inserted into the second insertion groove and slidably connected to the second insertion groove. That is, the hanging ear and the mounting arm are slidably connected at both the top and bottom ends. This makes it possible that when the tail sections of both arms on the chassis use the chassis mounting assembly provided in this application, on the one hand, the connection and relative sliding reliability between the hanging ear and the mounting arm in a single chassis mounting assembly is stronger; on the other hand, the mounting arm can provide better support for the chassis, further reducing the possibility of the tail section of the chassis sagging.

[0010] Optionally, the thickness of the first plug-in portion and the second plug-in portion is less than the thickness of the main body portion, so that the dimensions of the three components—the casing, the two hooks, and the casing itself—are more secure in the third direction after the two arms of the casing are connected to the hooks.

[0011] Optionally, the main body includes a first plate and a second plate stacked and fixed to the surface of the first plate. The side of the first plate facing away from the second plate is the first surface, and the side of the second plate facing away from the first plate is the second surface. The first insertion part, the second insertion part, and the second plate are integrally formed to facilitate the processing of the main body.

[0012] Optionally, the main body is a one-piece sheet metal part;

[0013] With the direction from the first plug-in portion to the second plug-in portion as the first direction, and the direction within the first surface perpendicular to the first direction as the second direction, the main body includes a first end and a second end located in the second direction. The first plate and the second plate 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 set of connecting holes, each set of connecting holes including multiple countersunk holes spaced apart. Each countersunk hole includes a first segment formed in the first plate and a second segment formed in the second plate, the second segment being used to accommodate the screw head. This facilitates the design of the countersunk holes and allows the screw head to be accommodated in the second segment, avoiding any impact of the screw head on the dimensions of the mounting assembly in the third direction. It also ensures smooth sliding between the mounting lug and the mounting arm.

[0015] Optionally, the main body includes three sets of connecting holes arranged sequentially along the second direction, wherein each set of connecting holes includes four countersunk holes arranged in a rectangular shape, and the distribution area of ​​the middle set of connecting holes in the second direction is larger in the first direction than the distribution area of ​​the other two sets of connecting holes in the first direction.

[0016] The first insertion portion includes two first sub-insertion portions, and the second insertion portion includes two second sub-insertion portions. Each of the two first sub-insertion portions and the two second sub-insertion portions is opposite to one of the two connecting hole groups located on either side in the second direction, and the projection of each sub-insertion portion in the second direction overlaps with the projection of the distribution area of ​​the connecting hole group in the middle of the second direction. Both first sub-insertion portions can be inserted into the first insertion slot, and both second sub-insertion portions can be inserted into the second insertion slot. In this design, by considering the layout of the connecting hole groups and the layout of each sub-insertion portion, the size of the hook in the first direction can be minimized.

[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 part fixed to the mounting arm body and a second part fixed to the end of the first part away from the mounting arm body. The second part extends toward the head end and is used for insertion into the rear end of the frame. The tail end is also fixed with a connecting plate, which is located in the same plane as the first part and has a through hole for a connector to pass through. In this way, the mounting arm can be fixed to the rear column with a single locking device, reducing locking time and improving installation efficiency. At the same time, the adjustment and setting of the mounting arm's position at the rear end of the frame is also more convenient.

[0018] Optionally, the first end is provided with a guide plate, which is located on the side of the mounting arm body opposite to the first insertion slot, and the distance between the guide plate and the mounting arm body gradually increases along the direction opposite to the tail end. The guide plate serves to guide the lug as it slides into the mounting arm, facilitating the sliding connection between the lug and the mounting arm.

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

[0020] Optionally, the length of the connector slot is greater than the length of the corresponding connector portion; that is, the length of the first connector slot is greater than the length of the first connector portion, and the length of the second connector slot is greater than the length of the second connector portion. This allows the chassis mounting assembly provided in this embodiment to be applicable to racks of different depths, thus increasing its versatility.

[0021] The present invention also provides a communication device, including a frame, a housing, and any one of the housing mounting components provided in the above technical solutions. The tail of at least one arm of the housing is mounted to the rear end of the frame through the housing mounting component. Therefore, the possibility of the tail of the housing sagging on one side can be reduced, thereby reducing the possibility of the entire tail of the housing sagging. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-4 As shown in the figure, an embodiment of this application provides a chassis mounting assembly including a mounting arm 1 and a hook 2. The hook 2 includes a main body 21 and a first insertion part 22. The main body 21 is flat and is used to attach to and fix to the tail section 101 of the side wall of the chassis 100. The main body 21 includes a first surface 211 and a second surface 212 disposed opposite to each other. The first surface 211 is used to attach to the side wall of the chassis 100. The first insertion part 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. One end of the first insertion part 22 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.

[0036] The mounting arm 1 includes a mounting arm body 11 and a first insertion slot 12. The mounting arm body 11 is used to fix to the rear end of the frame 200. The first insertion 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 insertion part 22 can be inserted into the first insertion slot 12 and is slidably connected with the first insertion slot 12.

[0037] The tail sections 101 of both arms of the housing 100 are connected to the rear end of the frame 200 using the housing mounting assembly provided in this embodiment, which can reduce or even avoid the tail section of the housing 100 from sagging. Specifically, taking the connection of one side wall of the housing 100 as an example, the hanging ear 2 in the housing mounting assembly is fixed to the tail section 101 of the side wall of the housing 100, and the first surface 211 of the main body 21 of the hanging ear 2 is made to fit against 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 extends towards the front end of the frame 200. Then, the first insertion part 22 of the hanging ear 2 is inserted into the first insertion slot 12 and slidably connected with the first insertion slot 12. The first insertion slot 12 can support the tail section of the housing 100, thereby reducing the possibility of the tail section of the housing 100 sagging, or even avoiding the tail section of the housing 100 from sagging.

[0038] Furthermore, the direction pointing from the first insertion part 22 to the second insertion part 23 (mentioned later) is designated as the first direction a, the direction perpendicular to the first direction a within the first surface 211 is designated as the second direction b, and the direction perpendicular to the first direction a and the second direction b within the space is designated as the third direction c. The first insertion part 22 is plate-shaped. Compared to a groove-shaped structure, the dimensions of the plate-shaped first insertion part 22 in the first direction a and the third direction c are easier to control. This ensures that the dimensions of the chassis mounting assembly in the first direction a (i.e., the dimensions in the height direction of the chassis 100), and the dimensions of the chassis 100 and the two mounting ears 2 after connecting the two side arms of the chassis 100 in the third direction c, all do not exceed the dimensions required in this field. For example, in one specific implementation, the size of the housing 100 in the third direction c is 442mm, the size of the ear hook 2 in the third direction c is 2.7mm, and the sum of the sizes of the housing 100 and the two ear hooks 2 in the third direction c is 447.4mm, which is less than the 450mm required in the art. The size of the mounting arm 1 in the first direction a is 43.6mm, which is also less 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 refer to their positions when the mounting assembly is correctly installed on the rack 200. That is, the top of the main body 21 is the end of the main body 21 closest to the top of the rack 200, and the bottom of the main body 21 is the end of the main body 21 closest to the bottom of the rack 200; the top of the mounting arm body 11 is the end of the mounting arm body 11 closest to the top of the rack 200, and the bottom of the mounting arm body 11 is the end of the mounting arm body 11 closest to the bottom of the rack 200.

[0040] In one optional implementation of the aforementioned hanging ear 2, the hanging ear 2 includes a second insertion portion 23, which is connected to the top of the main body 21 and is opposite to the first insertion portion 22. The second insertion portion 23 extends away from the bottom of the main body 21, and one end of the second insertion 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 insertion groove 13, which is fixed to the top of the mounting arm body 11 and located on the side of the mounting arm body 11 facing the hanging ear 2; the second insertion portion 23 can be inserted into the second insertion groove 13 and slidably connected to the second insertion groove 13. In other words, the hook 2 and the mounting arm 1 are slidably connected at both the top and bottom ends. This means that when the tail sections 101 of both arms of the housing 100 adopt the housing mounting assembly provided in this embodiment, on the one hand, the connection and relative sliding reliability between the hook 2 and the mounting arm 1 in a housing mounting assembly are stronger; on the other hand, the mounting arm 1 can provide better support for the housing 100, further reducing the possibility of the tail of the housing 100 sagging.

[0041] For example, the length of the insertion slot is greater than the length of the corresponding insertion part. That is, the length of the first insertion slot 12 is greater than the length of the first insertion part 22, and the length of the second insertion slot 13 is greater than the length of the second insertion part 23. This makes the chassis mounting assembly provided in this embodiment applicable to racks 200 of different depths, thus increasing its versatility. Furthermore, both the first insertion part 22 and the second insertion part 23 can be elongated strips extending along the first direction a, so as to increase the contact area with the corresponding insertion slot while ensuring the dimensions in the first direction a and the third direction c, making the sliding connection between the lug 2 and the mounting arm 1 more reliable. In an optional implementation, the first insertion part 22 and the second insertion part 23 are symmetrical structures, and the first insertion slot 12 and the second insertion slot 13 are also symmetrical structures.

[0042] Optionally, each plug-in part may have a chamfered structure e at both corners away from the main body 21. The chamfered structure e can guide each plug-in part during the insertion of it into the corresponding plug-in slot, thus making it easier for each plug-in part to be inserted into the corresponding plug-in slot.

[0043] In one specific implementation, the thickness of the first plug-in portion 22 and the second plug-in portion 23 is less than the thickness of the main body portion 21, so that the dimensions of the three components—the box 100, the box 100, and the two plug-in portions 2—are more guaranteed in the third direction c after the two arms of the box 100 are connected to the hanging ears 2.

[0044] Furthermore, when specifically setting up the aforementioned main body 21, such as... Figure 5 and Figure 6 As shown, in one optional implementation, the main body 21 includes a first plate 213 and a second plate 214 stacked and fixed to the surface of the first plate 213. 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 insertion part 22, the second insertion part 23, and the second plate 214 are integrally formed. Exemplarily, the first insertion part 22, the second insertion part 23, and the second plate 214 can be integrally formed from the same sheet material of uniform thickness.

[0045] Furthermore, in one optional implementation, the main body 21 is a one-piece 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 sheet metal is folded in half and the fold line is pressed to obtain the aforementioned stacked first plate 213 and second plate 214. One end of the pressed edge is the aforementioned first end 220. The first plate 213 and the second plate 214 can be fixedly connected at the second end 230 by rivets.

[0046] In one optional implementation, the main body 21 is provided with at least one set of connecting holes, each set of connecting holes being used to connect with the side wall of a housing 100, thereby further improving the versatility of the housing mounting assembly provided in this embodiment. Specifically, each set of connecting holes includes a plurality of spaced countersunk holes 241, each countersunk hole 241 including a first hole segment 2411 formed in the first plate 213 and a second hole segment 2412 formed in the second plate 214, the second hole segment 2412 being used to accommodate the head of the screw 300. In this way, it is convenient to set the countersunk holes 241, and the head of the screw 300 can be accommodated in the second hole segment 2412, which can avoid the influence of the head of the screw 300 on the dimensions of the housing mounting assembly in the third direction c. It can also ensure smooth sliding between the lug 2 and the mounting arm 1. Exemplarily, the screw 300 passes through the main body 21 and is locked to the housing 100.

[0047] In one specific implementation, the main body 21 includes three sets of connecting holes arranged sequentially along the second direction b. Each set of connecting holes includes four countersunk holes 241 arranged in a rectangle. The distribution area of ​​the middle connecting hole set in the second direction b is larger than the distribution area of ​​the other two connecting hole sets in the first direction a, and the distribution areas of the two connecting hole sets on the sides of the second direction b are also different in the first direction a. That is, the spacing between adjacent countersunk holes 241 in each connecting hole set is different, and the three connecting hole sets are used to connect different sizes of housings. The first insertion part 22 includes two first sub-insertion parts 221, and the second insertion part 23 includes two second sub-insertion parts 231. The two first sub-insertion parts 221 and the two second sub-insertion parts 231 are each opposite to the two connecting hole sets on the sides of the second direction b. The projection of each sub-plug portion in the second direction b overlaps with the projection of the distribution area of ​​the connecting hole group located in the middle of the second direction b in the second direction b. That is, in the first direction a, the two first sub-plug portions 221 and the two second sub-plug portions 231 are opposite each other, and the distance between the connection point of the first sub-plug portion 221 and the main body portion 21 and the corresponding connection point of the second sub-plug portion 231 and the main body portion 21 is d1. The size of the distribution area of ​​the connecting hole group located in the middle of the second direction b in the first direction is d2, and d1 is smaller than d2. Both first sub-plug portions 221 can be inserted into the first plug slot 12, and both second sub-plug portions 231 can be inserted into the second plug slot 13. In this scheme, by combining the layout of the connecting hole group and the layout of each sub-plug portion, the size of the hanging ear 2 in the first direction a can be minimized as much as possible. For example, a separating mark 215 can be provided between each two adjacent connecting hole groups on the main body portion 21 to facilitate the installer to distinguish between adjacent connecting hole groups.

[0048] Of course, in other implementations, the outline of the main body 21 can also be rectangular, with each plug-in part connected to the corresponding edge of the main body 21.

[0049] Furthermore, based on the above three sets of connecting holes, the main body 21 may also include another set of connecting holes. For example, the main body 21 may also have a set of connecting holes, 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 three sets of connecting holes, so as to make fuller use of the space on the main body 21 of the hook 2 while expanding the versatility of the mounting components of the housing.

[0050] When specifically configuring the mounting arm 1, one possible implementation is as follows: Figures 7-11As shown, the mounting arm body 11 includes a head end 111 and a tail end 112. The tail end 112 is connected to at least one L-shaped bending structure 14. The L-shaped bending structure 14 includes a first part 141 fixed to the mounting arm body 11 and a second part 142 fixed to the end of the first part 141 away from the mounting arm body 11. The second part 142 extends toward the head end 111 and is used for insertion into the rear end of the frame 200. The tail end 112 is also fixed with a connecting plate 15. The connecting plate 15 and the first part 141 are located in the same plane and have a through hole 151 for the connector to pass through. For example, the connecting plate 15 has the aforementioned through hole 151, and the through hole 151 is an elongated hole extending along a third direction c. In this way, the mounting arm 1 can be fixed on the rear column 201 by a single 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 frame 200 is also more convenient.

[0051] Furthermore, the two apex corners of the second part 142 away from the first part 141 can be chamfered to facilitate alignment with the corresponding mounting holes at the rear end of the frame 200.

[0052] In one 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, which are arranged sequentially along a first direction a, and the connecting plate 15 is located between the two L-shaped bending structures 14 along the first direction a.

[0053] In one optional implementation, the first end 111 of the mounting arm body 11 is provided with a guide plate 16. The guide plate 16 is located on the side of the mounting arm body 11 away from the first insertion groove 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. That is, the guide plate 16 is inclined relative to the mounting arm body 11, forming an inclined surface for guiding the sliding of the lug 2, so that the guide plate 16 plays a guiding role in the process of the lug 2 sliding into the mounting arm 1, so as to facilitate the sliding connection between the lug 2 and the mounting arm 1.

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

[0055] For example, the mounting arm 1 can be a one-piece molded structure.

[0056] In one optional implementation, the length of the mounting arm 1 is adjustable, thereby making the chassis mounting assembly provided in this embodiment more versatile. Specifically, the mounting arm 1 may include two slidably connected sub-mounting arms, which can slide relative to each other in the second direction b, so that the length of the mounting arm 1 is adjustable.

[0057] The enclosure mounting assembly provided in this embodiment has a simple structure, low cost, high strength and quality, and is easy for users to install and use.

[0058] like Figure 8 As shown, the communication device provided in this embodiment includes a rack 200, a housing 100, and the aforementioned housing mounting assembly. At least one tail of the housing 200 is mounted to the rear end of the rack via the housing mounting assembly. Therefore, the possibility of sagging at least one tail of the housing 200 can be reduced, thereby reducing the possibility of sagging of the entire tail of the housing 200.

[0059] For example, the rack 200 includes a front frame 202 and a rear frame, and the number of housings 100 is at least one. Each side wall of the housing 100 corresponds to at least one housing mounting component. The front end of each housing 100 is fixed to the front frame 202. The mounting arm 1 in each housing mounting component is fixed to the rear frame and extends toward the front frame 202. Each plug-in part is inserted into a corresponding plug-in slot. That is, the first plug-in part is inserted into the first plug-in slot, and the second plug-in part is inserted into the second plug-in slot. In this solution, at least one of the above-mentioned housing mounting components is used at the tail sections 101 of both sides of the housing 100 to connect the tail of the housing 100 to the rear end of the rack 200, which can reduce or even avoid the tail of the housing 100 from drooping. Specifically, taking a mounting assembly corresponding to one side wall of the chassis 100 as an example, the lug 2 in the mounting assembly is fixed to the tail section 101 of the side wall of the chassis 100, and the first surface 211 of the main body 21 of the lug 2 is in contact 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 extends toward the front end of the frame 200. The first insertion part 22 of the lug 2 is inserted into the first insertion slot 12 of the mounting arm 1 and is slidably connected with the first insertion slot 12. The first insertion slot 12 can support the tail of the chassis 100, thereby reducing the possibility of the tail of the chassis 100 sagging, or even preventing the tail of the chassis 100 from sagging.

[0060] Furthermore, 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. This ensures that the dimensions of the chassis mounting assembly in the first direction a (that is, the dimensions in the height direction of the chassis 100), and the dimensions of the chassis 100 and the two hanging ears 2 after connecting the two arms of the chassis 100 in the third direction c do not exceed the dimensions required in this field.

[0061] It is worth noting that when multiple chassis mounting components are located on one side wall of chassis 100, the multiple chassis mounting components can be arranged sequentially along the first direction.

[0062] For example, the front frame 202 may include two front columns spaced apart along a third direction c, and the rear frame may include two rear columns 201 spaced apart along a third direction c. The mounting arm 1 is fixedly connected to the corresponding rear column 201. For example, the rear column 201 is provided with a plurality of mounting holes penetrating along a second direction b. The second part 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 to a nut, thereby fixing the mounting arm 1 to the rear column 201.

[0063] It is worth noting that the communication equipment mentioned in this embodiment can be a switch or server, or other equipment including a chassis 100 and a rack 200. The chassis 100 may contain a main control module and / or a communication module.

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

[0065] Step 1: Secure the two hooks 2 to the corresponding holes on the side walls of the casing 100, such as... Figure 4 As shown;

[0066] Step 2: Secure the two mounting arms 1 to the two rear columns 201 of the frame 200 respectively;

[0067] Step 3: Align the housing 100 with the hanging ears 2 on both sides with the two mounting arms 1 that were locked to the rear column 201 in Step 2, so that the two hanging ears 2 are slidably connected to the corresponding mounting arms 1 respectively.

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

[0069] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
