With continued reference to FIG. 1, in order to improve the movement of the cable 70, the subrack provided in the embodiment of the present application defines the cable 70. When specifically defined, it is realized by two parts, one is a fixed limit assembly, and the other is a slidable clamping assembly 50. The limiting component and the clamping component 50 jointly define the bending direction of the cable 70 and the moving direction of the cable 70 when the subrack moves. In order to conveniently describe the structure of the subrack provided in the embodiment of the present application, the subrack body 10 is defined. When the subrack body 10 is inserted into the cabinet 60, the end of the exposed cabinet 60 is the first end and the end close to the cabinet 60 Is the second end. As shown in Figure 1, the A end is the first end, and the B end is the second end. When the subrack is pulled out, the direction of motion is from the B end to the A end. When pushing in, the moving direction is from the A end to the B end.

First, for the limiting component, the limiting component is used to fix the bending direction of the cable 70. When specifically fixed, the routing direction and routing path of the cable 70 may be defined as needed.

The first limiting plate 20 is a vertically arranged limiting plate. When the first limiting plate 20 limits the cable 70, the cable 70 is fixed by a hook 211 provided to make the cable 70 It extends along the first limit plate 20. When specifically setting the first limit plate 20, different structural forms may be adopted. FIG. 1 shows a specific structure of the first limit plate 20. In the first limit plate 20 shown in FIG. It includes two parts, namely a vertical portion 22 and an arc-shaped bending portion 21 connected to the vertical portion 22. When the first limit plate 20 is specifically provided, the length direction of the vertical portion 22 is along the direction from the A end to the B end, and the arc-shaped bending portion 21 is connected to the end of the vertical portion 22 near the B end, and the The concave portion of the arc-shaped bending portion 21 is reversed toward the A end, so that the cable 70 is bent along the outer arc surface of the arc-shaped bending portion 21 after extending along the vertical portion 22, and the arc shape is specifically provided When bending the portion 21, the radius of the arc-shaped bending portion 21 should be greater than the minimum bending radius of the cable 70 (the minimum radius allowed for bending without the cable 70 being damaged). When the curved bent portion 21 is specifically provided, as shown in FIG. 1, the bent portion of the curved bent portion 21 is located on the left side of the vertical portion 22, and when the cable 70 is fixed, the hook 211 is provided on the arc-shaped bending portion 21, and the cable 70 is restricted to bend along the arc of the arc-shaped bending portion 21 by the hook 211. When the hook 211 is specifically provided, as shown in FIG. 1, the number of the hook 211 is two, and the two hooks 211 are provided on the outer arc surface of the curved bending portion 21. Moreover, when two hooks 211 are provided, the two hooks 211 are located at the ends of the arc-shaped bending portion 21 respectively. Of course, for the number of hooks 211 and the installation position, the structure shown in FIG. 1 is only an example. The hooks 211 provided in the embodiments of the present application may use one, two, three, etc. different numbers, and The installation position of the hook 211 is not limited to both ends of the curved bending portion 21. When the first limit plate 20 fixes the cable 70, as shown in FIG. 2, FIG. 2 shows the situation when the cable 70 is fixed, the cable 70 extends along the vertical portion 22, and extends to an arc shape After the bending portion 21, the cable 70 is fixed by a hook 211 provided so that the cable 70 is bent along the arc of the curved bending portion 21, and the bent cable 70 is connected to the module.

When the arc-shaped bending portion 21 and the vertical portion 22 are specifically provided, the vertical portion 22 and the arc-shaped bending portion 21 may adopt an integrated structure. At this time, the arc-shaped bending portion 21 and the vertical portion 22 are integrated by It can be formed by molding, and it can also adopt a split structure. At this time, the curved bent portion 21 and the vertical portion 22 may be connected or not connected. When connected, one end of the curved bent portion 21 is connected to One end of the vertical portion 22 is connected. When not connected, the arc-shaped bending portion 21 and the vertical portion 22 are fixedly connected to the frame main body 10 respectively, and the ends of the arc-shaped bending portion 21 and the vertical portion 22 close to each other may be in direct contact or may be spaced at a certain interval gap.

Of course, it should be understood that the first limit plate 20 shown in FIG. 1 is only a specific structure of the first limit plate 20 provided in the embodiment of the present application. The first limit position provided in the embodiment of the present application In addition to the structure shown in FIG. 1, the board 20 may adopt other methods, such as an S-shaped or U-shaped structure. It only needs to be able to define the bending direction of the cable 70.

However, no matter which kind of first limiting plate 20 is used, a split structure or an integrated structure may be used between the first limiting plate 20 and the main frame body 10. When the split structure is adopted, the first limiting plate 20 may be fixedly connected to the subframe by bonding, welding, or connecting pieces (bolts, screws, rivets). When the integrated structure is used, the first limiting plate 20 can be formed integrally when the insert frame is prepared.

As can be seen from the first limiting plate 20 shown in FIG. 1, when the first limiting plate 20 shown in FIG. 1 is used, the cable 70 is bent once. When the cable 70 is connected to the module, it needs to be bent again. In order to limit the bending, when setting the limit component, as shown in FIG. 1, the limit component is also provided for fixing the The first fixing member 30 of the cable 70 and the second fixing member 40 for fixing the cable 70. And the first fixing member 30 and the second fixing member 40 are used in combination to define the bending direction of the cable 70, and when specifically defined, the first fixing member 30 and the second fixing member 40 define the bending direction of the cable 70 and The first limiting plate 20 defines that the bending direction of the cable 70 is opposite. As shown in FIG. 2, through the definition of the first limit plate 20 and the definition of the first fixing member 30 and the second fixing member 40, the cable 70 forms an S-shaped bend as shown in FIG. 2 The structure thus defines the entire routing square of the cable 70.

When the first fixing member 30 and the second fixing member 40 are specifically provided, the first fixing member 30 and the second fixing member 40 are used together, so that the cable 70 is between the first fixing member 30 and the second fixing member 40 Form a curved bend. Referring to FIG. 1, the first fixing member 30 is disposed below the arc-shaped bending portion 21, and the lower refers to a position close to the A end when the B end points toward the A end. Therefore, the cable 70 bent by the first limiting plate 20 enters the first fixing member 30 to be defined. When the first fixing member 30 is specifically provided, as shown in FIG. 1, the first fixing member 30 includes two opposed second limiting plates 31 and a third limiting plate 32, and the second limiting position The plate 31 and the third limiting plate 32 are fixedly connected to the main frame body 10 respectively, and when installed, there is a gap between the second limiting plate 31 and the third limiting plate 32 for accommodating the cable 70 In order to define the cable 70, the cable 70 passes between the second limiting plate 31 and the third limiting plate 32. When specifically defining the second limit plate 31 and the third limit plate 32, as shown in FIG. 1, the length direction of the second limit plate 31 and the third limit plate 32 is perpendicular to the direction from the A end to the B end And the second limiting plate 31 is located above the third limiting plate 32. Of course, the second limiting plate 31 and the third limiting plate 32 may also be provided in such a manner that the second limiting plate 31 and the third limiting plate 32 may be inclined downward to the right with respect to the direction in which the A end points to the B end.

In addition, when the second limiting plate 31 and the third limiting plate 32 are specifically provided, the end of the second limiting plate 31 away from the vertical portion 22 has a protrusion bent downward, and the third limiting plate 32 is close to One end of the vertical portion 22 has an upward protrusion, and the two protrusions are provided with a certain gap with the main frame body 10, when the cable 70 is fixed, the cable 70 is first clamped on the second limit plate In the gap between the protrusion on 31 and the frame body 10, the gap between the protrusion on the third limiting plate 32 and the frame body 10 is then engaged. Since the protrusion of the second limit plate 31 and the protrusion of the third limit plate 32 are arranged diagonally, as shown in FIG. 2, the cable 70 fixed by the first fixing member 30 has a certain Tilt (direction toward the B end relative to the A end).

For the second fixing member 40 therein, the second fixing member 40 is used to define the direction of the cable 70 when the cable 70 is connected to the module. As shown in FIGS. 1 and 2, the second fixing member 40 includes at least two fourth limiting plates 41 spaced apart, and a cable 70 is formed between two adjacent fourth limiting plates 41. space. As shown in FIG. 1, the number of the fourth limiting plates 41 is four, and the four fourth limiting plates 41 are arranged along the direction from the A end to the B end. The arrangement direction is the same as the direction in which the cable 70 is connected to the module. In the structure shown in FIG. 2, it can be seen that the cables 70 are sequentially arranged in the vertical direction (end A to end B) and connected to the module. Therefore, when the fourth limit plate 41 is provided, the fourth limit The direction in which the bit plates 41 are arranged is also arranged from the A end to the B end. When the arrangement direction when the cable 70 is connected to the module changes, the arrangement direction of the corresponding fourth limit plate 41 also changes to ensure the connection between the cable 70 and the module.

In addition, when specifically fixing the cable 70, each fourth limiting plate 41 is provided with a bending structure to form an inverted L-shaped structure. And the bending direction of the bending structure of each fourth limiting plate 41 is the same. In specific use, the cable 70 is clamped in the gap between the bending structure and the main frame body 10, thereby defining the fourth cable 70. It should be understood that, when the fourth limiting plate 41 is specifically provided, it is not limited to the structure shown in FIG. 2, and other structures capable of implementing the limiting cable 70 may also be used. If an inverted U-shaped structure is adopted, the cable 70 can be fixed by passing the cable 70 in the inverted U-shaped structure.

It can be seen from the above description that the cable 70 is limitedly bent by the cooperation of the first fixing member 30 and the second fixing member 40, and the bending direction is opposite to the limiting direction of the first limiting plate 20 , Thereby forming an S-shaped bend. However, when the first fixing member 30 and the second fixing member 40 are specifically defined, it should be understood that the minimum bending radius defined by the first fixing member 30 and the second fixing member 40 on the cable 70 should be greater than the cable 70 The minimum bending radius allowed to ensure the safety of the cable 70.

In addition, when the first fixing member 30 and the second fixing member 40 are specifically provided, the second limiting plate 31, the third limiting plate 32, and the fourth limiting plate 41 may be integrated with the frame body 10 Or split structure. When the split structure is adopted, the second limiting plate 31, the third limiting plate 32, and the fourth limiting plate 41 can be fixedly connected to the subframe by bonding, welding, or connecting pieces (bolts, screws, rivets). When the integrated structure is adopted, the second frame 31, the third plate 32 and the fourth plate 41 can be integrally prepared when the insert frame is prepared.

It can be seen from the above description that the end of the cable 70 connected to the module is limited by the limiting component, which defines the direction of its bending, and by the card on the first limiting plate 20 in the set limiting component The hook 211 fixes the cable 70. When the subrack is pulled out or pushed into the cabinet 60, the portion of the cable 70 defined by the limiting component will not follow the subrack to move. That is, the cable 70 between the hook 211 and the module will not follow the movement of the subrack. The cable 70 on the right side of the hook 211 will follow the movement of the subframe. When the subframe is pulled out, the cable 70 in this part is unfolded to ensure the connection between the module and the cabinet 60. When the subrack is pushed in, the cable 70 in this part is bent to form a redundancy. In order to ensure the safety of the cable 70 during the movement of the subrack, in the subrack provided in the embodiment of the present application, the folding assembly of the cable 70 during the movement is improved by adopting a clamping assembly 50 that is slidingly assembled on the subrack body 10 Bending situation.

When the sliding assembly is specifically implemented, a slide slot 11 is provided on the subrack body 10, the length direction of the slide slot 11 is the same as the sliding direction of the subrack body 10, wherein the first set position is that the slide slot 11 is close to A At the end of the end, the second set position is the end of the chute 11 near the B end. In addition, when the chute 11 is provided, different types of chute such as a linear chute or an arc chute can be used. As shown in FIG. 1, the length direction of the chute 11 is the direction from the A end to the B end. When the clamping assembly 50 is transferred into the chute 11, the clamping assembly 50 can be along the A end to the B end or B Slide end to end. When the clamping assembly 50 is specifically provided, as shown in FIG. 1, the clamping assembly 50 includes a support plate 51 slidably connected to the slide slot 11, and the support plate 51 is provided with a protrusion slidingly fitted in the slide slot 11 By sliding the protrusion in the sliding groove 11, the supporting plate 51 can slide on the main frame body 10. When the supporting plate 51 is provided, as shown in FIG. 1, the limiting plate adopts a rectangular supporting plate 51. Of course, the shape of the supporting plate 51 is not limited to the above rectangle, but other shapes may also be used, such as Round, oval or polygonal. In order to limit the cable 70, two opposite fifth limiting plates 52 and sixth limiting plates 53 are provided on the supporting plate 51, as shown in FIG. 1, the fifth limiting plates 52 and the sixth limiting plates 53 is oppositely disposed at both ends of the support plate 51, the two ends of the support plate 51 refer to the two ends of the support plate 51 opposite to the A end and the B end, and the fifth limit plate 52 and the sixth limit are provided The length direction of the bit plate 53 is perpendicular to the direction from the A end to the B end. As shown in FIG. 1, the limit plate near the A end is the fifth limit plate 52, the limit plate near the B end is the sixth limit plate 53, and the fifth limit plate 52 and the sixth limit plate 53 are A space for accommodating the cable 70 is formed therebetween. When limiting the cable 70, refer to FIG. 2 together. The cable 70 is passed between the fifth limiting plate 52 and the sixth limiting plate 53. In addition, in order to facilitate the bending of the cable 70, the specific setting When the fifth limiting plate 52 is used, the fifth limiting plate 52 is an arc-shaped limiting plate, and the concave direction of the fifth limiting plate 52 faces the B end. At this time, the concave direction of the fifth limiting plate 52 is away from the sixth limiting plate 53, so that the cable 70 between the fifth limiting plate 52 and the sixth limiting plate 53 can bend along the The outer arc surface of the fifth limiting plate 52 is bent. It should be understood that the radius of the fifth limiting plate 52 should be greater than the minimum bending radius of the cable 70 to ensure the safety of the cable 70 during bending .

Continuing to refer to FIGS. 1 and 2, in order to limit the cable 70 between the fifth limit plate 52 and the sixth limit plate 53, at least one limit position among the fifth limit plate 52 and the sixth limit plate 53 A bending structure defining cable 70 is provided on the board.

As shown in FIG. 3, the fixing member 80 is fixedly connected to the cabinet 60 and used to fix the cable 70. And the fixing member 80 is an elastic fixing member 80, and the elastic fixing member 80 is provided with a jack 82. When fixing the cable 70, the cable 70 is directly inserted into the jack 82, and the elastic force of the elastic fixing member 80 warps The cable 70 is clamped. As shown in FIG. 3, the height of the jack 82 is slightly smaller than the cable 70, so that the cable 70 can be clamped when the cable 70 is inserted, and the jack 82 is an elongated hole, so that in each module When there are multiple corresponding cables 70, they can be inserted into the jack 82 side by side for fixing. The definition of the fixing member 80 protects the connecting end of the cable 70 and the cabinet 60 from being pulled, so that the part of the cable 70 that follows the movement of the subrack is defined between the first limiting plate 20 and the fixing member 80 And, this part of the cable 70 also defines its movement trajectory through the clamping assembly 50, thereby improving the safety of the entire cable 70.

When the slot has multiple layers, and each layer is slidingly connected to a drawer module, there are also multiple sockets 82 in the corresponding fixing member 80. In a specific setting, the elastic fixing member 80 includes a plurality of stacked elastic protrusions 81, and each elastic protrusion 81 is provided with a socket 82; and the socket 82 corresponds to the drawer module one by one, and each layer is drawn The cable 70 connected to the pull module is correspondingly inserted into the jack 82. Thus, a multilayer fixed cable 70 can be realized. It is convenient for the unified management of the cable 70.

It can be seen from the above description of the communication device that the fixed member 80 cooperates with the limiting component and the clamping component 50 provided on the main body 10 of the subframe to define the fixed part on the cable 70 and follow the subframe The part that moves, and the part that follows the movement of the sub-frame also defines a bending manner (movement path) by the clamping assembly 50, thereby improving the safety of the entire cable 70 when the drawing module moves.
