Technical Field
[0001] This utility model belongs to the field of patch panel technology and relates to an optoelectronic hybrid patch panel. Background Technology
[0002] Optical Fiber Composite Cable (OPCC) is a composite cable that integrates optical fiber and metal twisted-pair wire (such as copper wire) into the same sheath. OPCC has the ability to transmit both optical and electrical signals and is a combination of optical fiber and electrical cable.
[0003] A patch panel is a device for centrally managing, terminating, and distributing network cables (such as Ethernet cables and fiber optic cables). Currently, most patch panels are only suitable for fiber optic or Ethernet cable wiring and not for wiring hybrid fiber optic cables, so there is room for improvement. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a hybrid optoelectronic patch panel.
[0005] The objective of this utility model can be achieved through the following technical solution: a hybrid optoelectronic patch panel, comprising:
[0006] A patch panel, the front face of which has a network cable termination area and an optical fiber termination area, wherein the network cable termination area is provided with a plurality of network cable connectors and the optical fiber termination area is provided with a plurality of optical fiber connectors.
[0007] A fusion splice tray, wherein the fusion splice tray is disposed inside the wiring box;
[0008] The fiber optic hybrid cable enters the distribution box from the rear end, the network cable in the fiber optic hybrid cable is connected to the network cable connector, and the optical fiber in the fiber optic hybrid cable is fused to the pigtail of the optical fiber connector through the fusion splice plate.
[0009] Preferably, the number of each network cable connector and each fiber optic connector are the same and correspond one-to-one.
[0010] Preferably, the device also includes a splitter, which has a main channel and a branch channel. The branch channel is connected to the main channel, and the main channel has several clamping blocks on its wall. The optoelectronic hybrid cable passes through one end of the main channel, and the splitter clamps the optoelectronic hybrid cable with the clamping blocks. The network cable and optical fiber of the optoelectronic hybrid cable separate at the junction of the main channel and the branch channel. The network cable of the optoelectronic hybrid cable exits from the other end of the main channel, and the optical fiber of the optoelectronic hybrid cable exits from the branch channel.
[0011] Preferably, the brancher is configured as a Y-shaped tubular structure or an r-shaped tubular structure.
[0012] Preferably, the brancher is configured as a two-half structure, the brancher including a first half tube and a second half tube, the first half tube and the second half tube being spliced together to form the main channel and the branch channel between them.
[0013] Preferably, one side of the first half-tube portion and one side of the second half-tube portion are hinged together by a hinge portion.
[0014] Preferably, one of the first half-tube portion and the second half-tube portion is provided with an elastic buckle and the other is provided with a snap-fit seat, and the branch has an open state and a closed state; when the branch is in the open state, the first half-tube portion and the second half-tube portion are not in contact; when the branch is in the closed state, the first half-tube portion and the second half-tube portion are in contact and the elastic buckle is snapped into the snap-fit seat.
[0015] Preferably, the patch panel includes a housing and a sliding base, the sliding base being slidably connected to the housing, and the network cable termination area, the optical fiber termination area, and the fusion splice tray are all disposed on the sliding base.

The travel positions of the locking hook include a locked position and an unlocked position. When the sliding seat is retracted into the housing, the locking hook is in the locked position under the action of gravity, the free end of the locking hook passes through the clearance opening, and the locking tongue engages with the front end face of the sliding seat to restrict the extension of the sliding seat. When the locking hook is raised to the unlocked position, the locking tongue separates from the front end face of the sliding seat to allow the sliding seat to slide.
[0017] Preferably, the free end of the locking hook is provided with an arcuate portion for interacting with the bottom surface of the clearance opening to lift the locking hook.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] 1. A patch panel is provided that can centrally manage, terminate, and distribute network and fiber optic cables, so this patch panel can be used for wiring of hybrid fiber optic cables.
[0020] 2. In the hybrid fiber-optic cable, the network cable and optical fiber are physically separated within the splitter. The network cable and optical fiber exit from the main channel and branch channel respectively, reducing mutual interference and simplifying subsequent cable management. Therefore, in this example, the network cable and optical fiber of the hybrid fiber-optic cable are split into two paths by the splitter. After entering the distribution box, the network cable and optical fiber are naturally separated by the splitter and run through different channels, avoiding the network cable and optical fiber from crossing and tangling inside the box, and facilitating the management of various cables.

Detailed Implementation
[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0031] like Figures 1 to 3 As shown, an optoelectronic hybrid patch panel includes:
[0032] The front end of the patch panel 100 has a network cable termination area 110 and an optical fiber termination area 120. The network cable termination area 110 is provided with a number of network cable connectors 111, and the optical fiber termination area 120 is provided with a number of optical fiber connectors 121.
[0033] Fusion splice 200 is installed inside the wiring box 100;
[0034] Among them, the fiber optic hybrid cable 300 is inserted into the distribution box 100 from the rear end of the distribution box 100. The network cable 310 in the fiber optic hybrid cable 300 is connected to the network cable connector 111. The optical fiber 320 in the fiber optic hybrid cable 300 is fused to the pigtail of the optical fiber connector 121 through the fusion splice plate 200.
[0035] This hybrid optical-electric patch panel integrates fiber optic cables (320) and network cables (310, such as twisted-pair cables) into a single device for management and distribution. The front face of the patch panel 100 is divided into two areas: a network cable termination area 110 with multiple standard network cable connectors 111 (such as RJ45 interfaces) for connecting Ethernet cables, and a fiber optic termination area 120 with multiple fiber optic connectors 121 (such as LC, SC, MPO, etc.) for optical signal access or distribution. A fusion splice tray 200 is used to achieve fusion splicing between fiber optic cables (320). The hybrid optical-electric cable 300 includes fiber optic cables (320) and several network cables (310, such as 8 twisted-pair cables). The hybrid cable 300 is branched within the patch panel 100, with network cables (310) directly connected to network cable connectors (111), and fiber optic cables (320) fused to pigtails via the fusion splice tray 200 and then connected to fiber optic connectors (121).
[0036] The design of this hybrid optical and electrical patch panel is that it can support 300mm access to hybrid optical and electrical cables, reducing wiring complexity, shortening the construction cycle, and all connection points are concentrated on the front panel, making it easy to plug, unplug, test, and replace.
[0037] Based on the above implementation method, the number of each network cable connector 111 and each fiber optic connector 121 is the same and they correspond one-to-one. Specifically, one network cable connector 111 corresponds to one fiber optic connector 121. The network cable 310 in a conductive hybrid cable is connected to the network cable connector 111, and the fiber optic cable 320 is connected to the fiber optic connector 121. The network port and optical port are numbered the same and located accordingly. Maintenance personnel can quickly identify the relationship between each interface, reduce the risk of misinsertion and incorrect connection, and improve the efficiency of troubleshooting.
[0038] like Figures 1 to 6As shown, based on the above embodiment, a brancher 400 is also included. The brancher 400 is provided with a main channel 440 and a branch channel 450. The branch channel 450 is connected to the main channel 440. The hole wall of the main channel 440 is provided with a plurality of clamping blocks 441. The optoelectronic hybrid cable 300 is inserted into one end of the main channel 440, and the brancher 400 clamps the optoelectronic hybrid cable 300 through the clamping blocks 441. The network cable 310 and the optical fiber 320 of the optoelectronic hybrid cable 300 are separated from the intersection of the main channel 440 and the branch channel 450. The network cable 310 of the optoelectronic hybrid cable 300 is inserted from the other end of the main channel 440, and the optical fiber 320 of the optoelectronic hybrid cable 300 is inserted from the branch channel 450.
[0039] In the hybrid fiber-optic cable 300, the network cable 310 and fiber optic cable 320 are physically separated within the splitter 400. The network cable 310 and fiber optic cable 320 exit from the main channel 440 and the branch channel 450 respectively, reducing mutual interference and simplifying subsequent cable management. Therefore, in this example, the network cable 310 and fiber optic cable 320 of the hybrid fiber-optic cable 300 are split into two paths by the splitter 400. The splitter 400 clamps the hybrid fiber-optic cable with clamping blocks 441, and the design of the clamping blocks 441 allows for clamping of hybrid fiber-optic cables of different diameters. After entering the distribution box 100, the network cable 310 and fiber optic cable 320 naturally separate through the splitter 400, running through different channels, avoiding cross-tangling and entanglement within the box, and facilitating the management of various cables.
[0040] Based on the above implementation, the brancher 400 is configured as a Y-shaped tubular structure or an r-shaped tubular structure.
[0041] Based on the above embodiments, the brancher 400 is configured as a two-half structure, including a first half tube 410 and a second half tube 420. The first half tube 410 and the second half tube 420 are spliced together to form a main channel 440 and a branch channel 450 between them.
[0042] The two-half structure, also known as the half-pipe structure, has the advantage of allowing installation without damaging the cable. The fiber optic hybrid cable 300 can be inserted into one half of the pipe first, and then closed by splicing the other half, avoiding the hassle of having to insert it from the end during installation.
[0043] In this example, the fiber optic hybrid cable 300 can be inserted into the back end of the patch panel 100 first. Then, the network cable 310 of the fiber optic hybrid cable 300 is connected to the network cable connector 111. Next, the fiber optic cable 320 is stripped, and the splitter 400 is installed at the branch point so that the fiber optic cable 320 at the branch point is located within half of the branch channel 450. Then, the two halves of the tube are closed to ensure that the fiber optic cable 320 is confined to the branch channel 450, and the bending angle of the fiber optic cable 320 at the branch point is precisely controlled to prevent the fiber optic cable 320 from bending.
[0044] Based on the above embodiment, one side of the first half-tube portion 410 and one side of the second half-tube portion 420 are hinged together by a hinge portion 430. The hinge portion 430 ensures that the two half-tube portions are always connected, and the two half-tube portions are kept closed and fixed by an elastic buckle 411 and a locking seat 412.
[0045] Based on the above embodiments, one of the first half-tube portion 410 and the second half-tube portion 420 is provided with an elastic buckle 411 and the other is provided with a locking seat 421. The branch 400 has an open state and a closed state. When the branch 400 is in the open state, the first half-tube portion 410 and the second half-tube portion 420 are not in contact. When the branch 400 is in the closed state, the first half-tube portion 410 and the second half-tube portion 420 are in contact and the elastic buckle 411 is locked with the locking seat 421.
[0046] When the splitter 400 is in the open state, the two half-tube sections are not touching, facilitating cable insertion and removal. When the two half-tube sections are touching, they form a closed, hole-like channel. The elastic buckle 411 and the locking seat 421 enable a detachable connection between the two half-tube sections. The engagement of the elastic buckle 411 and the locking seat 421 secures the two half-tube sections together and keeps them in a closed state. By moving the elastic buckle 411, it can be separated from the locking seat 421, thereby opening the splitter 400.
[0047] like Figures 1 to 3 As shown, based on the above embodiments, the patch panel 100 includes a housing 130 and a sliding base 140. The sliding base 140 is slidably connected to the housing 130. The network cable termination area 110, the optical fiber termination area 120, and the fusion splice tray 200 are all disposed on the sliding base 140.
[0048] By moving the sliding base 140, the network cable termination area 110, fiber optic termination area 120, and fusion splice tray 200 can be pulled out or pushed in from the housing 130. In this example, the sliding base 140 can be pulled out as a whole, facilitating technicians to inspect, plug, replace, or perform fusion splicing operations on the internal components.
[0049] like Figures 1 to 3 , Figure 7As shown, based on the above embodiment, a locking hook 150 is hinged to the side wall of the outer shell 130. The free end of the locking hook 150 has a locking tongue 151. A clearance opening 141 is provided on the side edge of the front end face of the sliding seat 140. The travel positions of the locking hook 150 include a locked position and an unlocked position. When the sliding seat 140 is retracted into the outer shell 130, the locking hook 150 is in the locked position under the action of gravity. The free end of the locking hook 150 passes through the clearance opening 141, and the locking tongue 151 latches onto the front end face of the sliding seat 140 to restrict the extension of the sliding seat 140. When the locking hook 150 is raised to the unlocked position, the locking tongue 151 separates from the front end face of the sliding seat 140 to allow the sliding seat 140 to slide.
[0050] When the sliding seat 140 retracts into the housing 130, the free end of the locking hook 150 rotates to the locked position under the action of gravity, and the locking tongue 151 passes through the clearance opening 141 and latches the front end of the sliding seat 140; after manually lifting the locking hook 150 to the unlocked position, the locking tongue 151 disengages from the front end of the sliding seat 140, allowing the sliding seat 140 to slide out without tools or complicated operations.
[0051] Based on the above embodiments, the free end of the locking hook 150 is provided with an arc-shaped surface 152 for interacting with the bottom surface of the clearance opening 141 to lift the locking hook 150.
[0052] During the process of the sliding seat 140 being pushed into the housing 130, the arcuate surface 152 at the free end contacts and interacts with the bottom surface of the clearance opening 141, thereby automatically lifting the locking tongue 151 so that it can pass through the clearance opening 141. When the sliding seat 140 is fully slid into the housing 130, the locking tongue 151 automatically falls under the action of gravity, thereby locking the front end face. When the sliding seat 140 tends to pull outward, the locking tongue 151 cannot be passively lifted due to the angle of the arcuate surface 152, thus achieving the automatic locking function.
[0053] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0054] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0055] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0056] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
