Description

Technical Field

[0001] The utility model relates to the technical field of network connection equipment, and in particular to a distribution frame body and a distribution frame. Background Art

[0002] A patch panel is a device used to connect terminal user lines or trunk lines. The patch panel is the most important component in the management subsystem and is the hub for cross-connecting the vertical trunk and horizontal wiring subsystems. A twisted pair patch panel is a type of patch panel, which is mostly used for horizontal wiring and usually includes a front frame and a rear frame. The front frame is used to connect the RJ-45 port of the hub device, and the rear frame is used to connect the twisted pair cables extending from the information socket.

[0003] The existing twisted pair wiring frames are mainly of two types: 24-port and 48-port. For the 24-port twisted pair wiring frame, the front frame is provided with 24 RJ-45 interfaces, and the rear frame needs to be matched with 24 groups of cable management holes (each group of cable management holes includes two cable management holes for inserting cable ties to fix the twisted pair) or 24 cable tie ports. The rear frame of the 48-port wiring frame needs to be matched with 48 groups of cable management holes (i.e., 96 cable management holes) or 48 cable tie ports. The large number of cable management holes or cable tie ports makes it more difficult to process the holes on the rear frame. At the same time, the cable tie fixing method also has problems such as cumbersome wiring, low efficiency, and easy aging and breakage of the cable tie. Furthermore, the 24-port and 48-port existing twisted pair wiring frames need to be designed with corresponding rear frames respectively. Not only is the versatility of wiring accessories poor, but the on-site wiring personnel need to match the rear frame before each wiring, so there are also problems such as low wiring efficiency and easy wiring errors.

[0004] In addition, in the existing shielded distribution frame, a shielded network module is installed in the front frame body. For this type of network module, since it is necessary to fix the shielding wire on the cable, the shielding wire needs to be led out from the module body to the outside of the metal shell and wrapped around the outer wall of the metal shell to achieve grounding. For example, in the existing Category 6 or Category 6A shielded network modules, the rear end needs to extend two semi-tubular bodies that cover each other. The two cover each other to form a network cable card hole, and the cable shielding wire can also be wrapped around the two semi-tubular bodies to achieve shielding wire grounding. However. The setting of the end semi-tubular body greatly increases the length of the shielded network module, which will increase the thickness of the front frame body, which will not only increase the volume of the front frame body, but also make it difficult to be compatible with non-shielded distribution frames.

[0035] like Figures 1 to 9 As shown, the wiring rack frame 10 provided in this embodiment includes a front frame 1 and a rear frame 2. The front frame 1 includes a front panel 11 and a module mounting seat 12. The front panel 11 has a plurality of panel interfaces 111 distributed in sequence along its length direction. The module mounting seat 12 is connected to the bottom of the front panel 11. The module mounting seat 12 has a module accommodating cavity 121 corresponding to the plurality of panel interfaces 111 and used to accommodate a network module. The rear frame 2 includes a connecting plate 21, two hanging plates 22 disposed at both ends of the connecting plate 21 and detachably engaged with the frame, and a plurality of cable clamping members 23 arranged in sequence along the length direction of the connecting plate 21; each cable clamping member 23 includes two symmetrically arranged elastic cards 231, and an inner cable accommodating cavity 23a and an inner cable limiting portion 23b are formed between the two elastic clamping pieces 231, and an inter-part cable accommodating cavity 23a' and an inter-part cable limiting portion 23b' are formed between adjacent cable clamping members.

[0036] The arrangement of the cable accommodating chamber 23a within the component and the cable accommodating chamber 23a' between the components enables the rear frame 2 provided by the utility model to provide almost double the cable accommodating chamber by arranging a small number of cable clamping components 23. Figure 1 and Figure 4 As shown, the wiring rack provided in this embodiment has a twenty-four-port structure. Four clamping member mounting plates 24 are arranged on the connection plate 21 of the rear frame 2, and six cable clamping members 23 and an independent elastic clamping piece 231 are distributed on each clamping member mounting plate 24. The six cable clamping members 23 and an independent elastic clamping piece 231 form a group of cable clamping components, and each cable clamping component can provide six cable accommodating cavities 23a within the component based on the six cable clamping members 23 to match the twenty-four panel interfaces 11 on the front panel 11. Further, six inter-component cable accommodating cavities 23a' are formed between the six cable clamping members 23 and between the last cable clamping member 23 and the independent elastic clamping piece 231. The six intra-component cable accommodating cavities 23a and the six inter-component cable accommodating cavities 23a' enable each cable clamping component to provide twelve cable accommodating cavities, and four cable assemblies can match the forty-eight panel interfaces on the front panel. That is, the rear frame provided in this embodiment is compatible with both a 24-port patch panel frame and a 48-port patch panel frame; the rear frame 2 has good versatility and only requires one set of molds for processing during manufacturing, which greatly reduces the manufacturing cost; at the same time, this setting also greatly facilitates the work of wiring personnel and improves wiring efficiency and wiring accuracy.

[0037] The clamp mounting plate 24 integrates a plurality of cable clamps into one and assembles them in a modular manner. This arrangement will be more conducive to the assembly, maintenance and replacement of each cable clamp assembly. However, the present invention does not impose any limitation on this. In other embodiments, a plurality of cable clamps may be directly mounted on the connecting plate; for example, twenty-four cable clamps and an independent elastic clamping piece are directly mounted on the connecting plate to provide forty-eight cable accommodating cavities. Alternatively, twenty-five cable clamps may be directly arranged on the connecting plate to provide twenty-five intra-piece cable accommodating cavities and twenty-four inter-piece cable accommodating cavities. Although this embodiment is described by taking a twenty-four-port patch panel frame and a forty-eight-port patch panel frame as examples. However, the present invention does not impose any limitation on this. The patch panel frame provided by the present invention is also suitable for patch panels with other numbers of interfaces, and in this case, only the number of cable clamps needs to be adjusted.

[0038] Specifically, Figure 4 and Figure 5As shown, each elastic snap-fitting piece 231 has a first curved portion 2311, a second curved portion 2312 and a third curved portion 2313. The bending directions of the first curved portion 2311 and the second curved portion 2312 are opposite so that the bending centers of the two are respectively located on both sides of the elastic snap-fitting piece 231, and the bending direction of the third curved portion 2313 is the same as that of the first curved portion 2311. This arrangement enables the two symmetrically arranged elastic snap-fitting pieces 231 to enclose an inner-piece cable accommodating cavity 23a at the first curved portion 2311 and form an inner-piece cable limiting portion 23b at the second curved portion 2312; correspondingly, the adjacent cable snap-fitting pieces 23 form an inter-piece cable accommodating cavity 23a' at the second curved portion 2312 and an inter-piece cable limiting portion 23b' at the third curved portion 2313. However, the present invention does not make any limitation to this. In other embodiments, two elastic clamping pieces can be arranged inside the cable clamping piece to form a cable accommodating cavity inside the piece at the second bend portion, and a cable limiting portion inside the piece can be formed at the third bend portion; correspondingly, adjacent cable clamping pieces can form a cable accommodating cavity between pieces at the first bend portion, and a cable limiting portion between pieces at the second bend portion.

[0039] In this embodiment, if Figure 8 and Fig. 9 As shown, each hanging plate 22 is provided with a hook 221 at the front end, which is detachably engaged in the slot on the module mounting seat 12 through the hook 221; each hanging plate 22 is provided with a shaft 222 at the rear end, which is rotatably connected to the two ends of the connecting plate 21 through the shaft 222 to be in an unfolded or folded state. Fig. 9 The method shown in the figure is to fold the connecting plate to reduce the volume of the rear frame 2. When installing, the rotating shaft 222 is rotated to unfold the hanging plate 22 to present Figure 1 The structure shown.

[0040] Specifically, two hooks 221 are disposed at the front end of each hanging plate 22, and the hooks of the two hooks 221 extend along the width direction of the hanging plate 21; the two hanging plates 22 are engaged in the slots on the module mounting seat 12 along the width direction of the module mounting seat 12. However, the present invention does not make any limitation to this. In other embodiments, the hanging plates may also be provided with longitudinally extending hooks to achieve longitudinal engagement.

[0041] In the existing patch panel, after the label is attached to the front panel, the transparent cover is snap-fitted to the front panel; when the label needs to be replaced, the transparent cover needs to be separated from the front panel, which is not only difficult to separate, but also the snap-fit ​​of the transparent cover is easily broken during the separation process, making it difficult to continue to use. Figure 6 and Figure 7As shown, in the wiring frame body provided in this embodiment, the front panel 11 also has a label receiving slot 112 located on one side of the plurality of panel interfaces 111, and the front frame body 1 also includes a transparent label cover 13 rotatably connected to the front panel 11 where the label receiving slot 112 is located, and the transparent label cover 13 opens or covers the label receiving slot 112. Specifically, as Figure 7 As shown, the two ends of the transparent label cover 13 are provided with rotating pins 131, and the rotating pins 131 are rotatably connected to the inner walls of the two ends of the label accommodating groove 112, so as to realize the rotation of the transparent label 13 to cover or open, which greatly facilitates the replacement of the label.

[0042] Correspondingly, this embodiment also provides a patch panel. Fig.10 As shown, the patch panel includes the patch panel frame 10 and a plurality of network modules 20. The plurality of network modules 20 are respectively embedded in a plurality of module accommodating cavities 121 on the module mounting seat 12 and extend into the corresponding panel interface 111. In this embodiment, the network module 20 is a shielded network module, such as a shielded network module of the category 5, category 5e, category 6, and category 6e. However, the present invention does not make any limitation to this. In other embodiments, the network module may also be a non-shielded network module.

[0043] In this embodiment, the network module 20 includes a metal shell 201, a main body module 202, and a cable management seat 203. The metal shell 201 is a hollow structure and its rear end wall 2012 is substantially flat. The rear end of the metal shell 201 is an openable structure. The module body 202 is accommodated in the metal shell 201 and extends to the front end of the metal shell 201. The front end of the module body 202 is formed with a socket for a detachable network connector. The cable management seat 203 is accommodated in the metal shell 201 and plugged into the rear end of the module body 202. The plug-in front end of the cable management seat 203 is formed with a plurality of engagement grooves 2031 for engaging the cable cores. The rear end of the cable management seat 203 is formed with a wiring channel 2032 connected to the inner cavity of the metal shell 201, and a shielding cavity 2033 is formed between the outer peripheral wall at the rear end of the cable management seat 203 and the metal shell 201; the shielding wire on the cable fixed to the cable management seat 203 extends from the cable management seat 203 into the metal shell 201 through the wiring channel 2032 and is accommodated in the shielding cavity 2033 and is electrically connected to the metal shell 201.

[0044] Based on the arrangement of the wiring channel 2032 on the cable management seat 203 and the shielding cavity 2033 between the cable management seat 203 and the metal shell 201, the cable shielding wire on the cable management seat 203 can extend from the wiring channel 2032 into the shielding cavity 2033 and contact the inner wall of the metal shell 201 to achieve grounding shielding; at the same time, the shielding cavity 2033 is also surrounded by the shielding wire to prevent it from detaching. The shielded network module provided in this embodiment uses a built-in method to connect the shielding wire to the ground. On the one hand, this arrangement makes it unnecessary for the shielding wire to extend to the outside of the metal shell and has a better shielding effect. On the other hand, this arrangement also makes it unnecessary to set a tubular or semi-tubular component on the metal shell 201 to achieve the winding shielding of the shielding wire, that is, the rear end of the metal shell 201 can be set in a plane to shorten its length. This arrangement realizes the short body and small volume design of the shielded network module, so that the shielded network module and the non-shielded network module can share the front frame, which not only greatly reduces the manufacturing cost but also does not need to be distinguished during wiring to improve the wiring efficiency and reduce the wiring error rate.

[0045] Specifically, Figures 10 to 14 As shown, the rear end of the cable management seat 203 is formed with a wiring portion 2034 extending to the rear end wall of the metal shell, and the peripheral wall of the wiring portion 2034 is formed with a wire clamping groove extending to its end, and the wire clamping groove forms a wiring channel 2032 connecting the cable management seat 203 and the shielding cavity 2033; further, the width of the wire clamping groove is set to be smaller to achieve the clamping and fixing of the shielding wire. However, the utility model does not make any limitation to this. In other embodiments, a through hole may also be formed on the peripheral wall of the wiring portion, and a wiring channel is formed at the through hole. Alternatively, in other embodiments, the rear end of the cable management seat may not be fully extended to the rear end wall of the metal shell (that is, the cable management seat is shorter than the metal shell), and a wiring channel is formed between the rear end of the cable management seat and the rear end wall of the metal shell.

[0046] In this embodiment, if Fig.14 As shown, a wire hole 2010 for passing the cable is formed on the rear end wall 2012 of the metal shell 201, and a concave cavity 2013 is formed between the rear end wall 2012 of the metal shell 201 and its peripheral wall 2011. The concave cavity 2013 and the rear end peripheral wall of the cable management seat 203 are surrounded by a shielding cavity 2033. However, the present invention does not impose any limitation on this. In other embodiments, a shielding cavity can also be formed based on the gap between the inner peripheral wall of the metal shell and the rear end peripheral wall of the cable management seat. In order to further increase the space of the shielding cavity 2033 so that the shielded wire can be better received in the shielding cavity and abut against the inner wall of the metal shell 201 for grounding and shielding, the present embodiment also arranges the outer peripheral wall 2035 of the cable management seat where the wiring channel 2032 is located to be rounded to increase the space of the shielding cavity 2033, as shown in FIG. Fig.13 However, the present invention does not impose any limitation on this.

[0047] In summary, in the wiring rack frame and wiring rack provided by the present invention, the rear frame includes a plurality of cable clamps arranged in sequence along the length direction of the connecting plate. Each cable clamp includes two symmetrically arranged elastic cards, and the two elastic clamps are surrounded by an inner cable accommodating cavity and an inner cable limiting portion, and the adjacent cable clamps are surrounded by an inter-component cable accommodating cavity and an inter-component cable limiting portion. The arrangement of the inner cable accommodating cavity and the inter-component cable accommodating cavity enables the rear frame provided by the present invention to provide almost double the cable accommodating cavity by arranging a small number of cable clamps, and the rear frame of the twenty-four-port wiring rack can be matched with the front frame of the forty-eight-port wiring rack, which greatly improves the versatility of the rear frame. The arrangement of the cable clamps does not require holes to be opened on the rear frame and does not require the assistance of cable ties, which not only effectively reduces the design difficulty of the rear frame, but also greatly improves the wiring efficiency.

[0048] As for the shielded distribution frame, in the shielded network module, a wiring channel connected to the inner cavity of the metal shell is formed at the rear end of the cable management seat. The shielded wires in the cables engaged on the cable management seat can extend through the wiring channel into the shielding cavity between the outer peripheral wall at the rear end of the cable management seat and the metal shell and be electrically connected to the inner wall of the metal shell to achieve grounding shielding. The provision of the wiring channel and the shielding cavity enables the shielded network module provided in this embodiment to achieve built-in shielding, and the shielding wire no longer needs to extend to the outer wall of the metal shell for grounding. Therefore, the rear end of the metal shell does not need to be provided with a shielding wire winding portion and is roughly planar, shortening the length of the shielded network module to shorten the module accommodating cavity, effectively reducing the cost and volume of the front frame.

[0049] Although the present invention has been disclosed as above by the preferred embodiment, it is not intended to limit the present invention. Anyone familiar with this technology can make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope required by the claims.
