Description

Technical Field

[0001] This utility model relates to the field of coarse wavelength division multiplexer technology, and more specifically, to a box-type dustproof silicon-based coarse wavelength division multiplexer. Background Technology

[0002] A coarse wavelength division multiplexer (CWDM) is an optical device used to multiplex multiple optical signals of different wavelengths into a single optical fiber, or to demultiplex these signals from a single optical fiber onto multiple wavelength channels. It is typically used in short- and medium-distance optical communication systems, such as metropolitan area networks (MANs) and access networks. However, existing CWDMs often experience connection problems and instability during the connection process due to the large number of internal optical fibers. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a box-type dustproof silicon-based coarse wavelength division multiplexer, which has the advantage of facilitating the arrangement and connection of the lines.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a box-type dustproof silicon-based coarse wavelength division multiplexer, comprising a multiplexer, a first port and a second port fixedly installed at the rear of the multiplexer, connecting plates fixedly installed on both the left and right sides of the multiplexer, and support plates fixedly installed on both the upper and lower sides of the connecting plates. A sliding groove is formed inside the support plate, and a slider is slidably connected inside the sliding groove. A limiting plate is fixedly installed on the side of the slider away from the sliding groove, and a slot is formed inside the limiting plate. A limiting block is fixedly installed inside the slot.

[0005] As a preferred embodiment of this utility model, a stud is inserted into the inside of the limiting plate, a spring is sleeved on the outside of the stud, and a nut is engaged on the side of the stud away from the spring.

[0006] As a preferred embodiment of this utility model, the limiting plate has a wire groove inside, the support plate has a fixing plate fixedly installed on the outside, and the fixing plate has a screw hole inside.

[0007] As a preferred embodiment of this utility model, a dustproof plate is fixedly installed at the rear of the multiplexer. The dustproof plate has multiple dustproof holes inside, and all of the multiple dustproof holes are located above the first port and the second port.

[0008] As a preferred embodiment of this utility model, there are multiple second ports, all of which are located behind the multiplexer and are distributed vertically.

[0009] As a preferred embodiment of this utility model, there are four support plates located behind the multiplexer. There are four sliding grooves and four sliding blocks, with the four sliding grooves slidably connected to the four sliding blocks respectively. There are two limiting plates, which are installed through the sliding connection between the four sliding blocks and the four sliding grooves respectively.

[0010] As a preferred technical solution of this utility model, there are multiple slots and limiting blocks, and the multiple slots and multiple limiting blocks are respectively located inside the two limiting plates.

[0011] As a preferred embodiment of this utility model, there are four studs and four springs, with the four studs and four springs located in the middle of the four support plates respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a sliding groove inside a support plate, with a slider slidably connected inside the groove. A limiting plate is fixedly installed on the side of the slider away from the groove. A slot is also provided inside the limiting plate, with a limiting block fixedly installed inside the slot. When installing optical fibers, the fiber is first inserted from inside the limiting plate into the slot. The limiting block then limits and compresses the fiber, preventing it from falling off. The limiting plate is then installed behind the multiplexer via the sliding action of the slider and the groove. The fiber interfaces are then plugged into the corresponding first and second ports, thus organizing the fiber lines and preventing them from becoming disordered due to excessive lines.

[0014] 2. This utility model features a stud inserted inside a limiting plate, a spring sleeved on the outside of the stud, and a nut engaged on the side of the stud furthest from the spring. When the fiber optic interface is inserted into the first and second ports, the stud, located in the middle of the limiting plate and the connecting plate, engages with the nut. This causes the spring to contract, compressing the limiting plate and shortening the distance between it and the first and second ports. Simultaneously, the small diameter of the slot ensures that the limiting plate, upon contact with the fiber optic interface, compresses and limits the interface, preventing loosening and unstable connection after prolonged use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a box-type dustproof silicon-based coarse wavelength division multiplexer, including a multiplexer 1. A first port 2 and a second port 3 are fixedly installed at the rear of the multiplexer 1. Connecting plates 4 are fixedly installed on both the left and right sides of the multiplexer 1. Support plates 5 are fixedly installed on both the upper and lower sides of the connecting plates 4. A sliding groove 6 is opened inside the support plate 5. A slider 7 is slidably connected inside the sliding groove 6. A limiting plate 8 is fixedly installed on the side of the slider 7 away from the sliding groove 6. A slot 9 is opened inside the limiting plate 8. A limiting block 10 is fixedly installed inside the slot 9.

[0023] When fiber optic cable installation is required, the fiber optic cable is first inserted from the inside of the limiting plate 8 into the inside of the slot 9. At the same time, the limiting block 10 will limit and squeeze the cable to prevent the fiber optic cable from falling off. Meanwhile, the limiting plate 8 is installed behind the multiplexer 1 by the sliding action of the slider 7 and the sliding groove 6. Then, the fiber optic cable interface is plugged into the corresponding first port 2 and second port 3, thereby organizing the fiber optic cable and preventing the cable from becoming messy due to too many cables.

[0024] The limiting plate 8 has a stud 11 inserted inside, a spring 12 sleeved on the outside of the stud 11, and a nut 13 engaged on the side of the stud 11 away from the spring 12.

[0025] When the fiber optic interface is plugged into the first port 2 and the second port 3, the stud 11 is located in the middle of the limiting plate 8 and the connecting plate 4, causing the stud 11 to engage with the nut 13. At this time, the spring 12 contracts, causing the limiting plate 8 to be squeezed and the distance between it and the first port 2 and the second port 3 to shorten. At the same time, because the diameter of the slot 9 is small, the limiting plate 8 will squeeze and limit the interface after contacting the fiber optic interface, preventing the interface from becoming loose and unstable after long-term use.

[0026] The limiting plate 8 has a wire groove 14 inside, and the support plate 5 has a fixing plate 15 fixedly installed on the outside. The fixing plate 15 has a screw hole 16 inside.

[0027] The main function of the fixing plate 15 is to connect with bolts through the screw holes 16, so that the multiplexer 1 can be fixedly installed inside the electrical cabinet, thus achieving the effect of easy installation.

[0028] Among them, a dustproof plate 17 is fixedly installed at the rear of the multiplexer 1. The dustproof plate 17 has multiple dustproof holes 18 inside, and all the multiple dustproof holes 18 are located above the first port 2 and the second port 3.

[0029] The main function of the multiple dust holes 18 is to prevent dust from falling into the surface of the first port 2 and the second port 3 after long-term use, thus preventing unstable fiber optic connections.

[0030] There are multiple second ports 3, all of which are located behind the multiplexer 1 and are distributed vertically.

[0031] The main function of multiple second ports 3 is to facilitate the conversion of various signals and improve the efficiency of the connection.

[0032] There are four support plates 5, which are located behind the multiplexer 1. There are four slide grooves 6 and four sliders 7. The four slide grooves 6 are slidably connected to the four sliders 7 respectively. There are two limit plates 8, which are installed through the sliding connection between the four sliders 7 and the four slide grooves 6 respectively.

[0033] The main function of the two limiting plates 8 is to limit the connection of the interface by sliding the four sliders 7 and the four grooves 6, thereby improving the stability after installation.

[0034] There are multiple slots 9 and multiple limit blocks 10, and the multiple slots 9 and multiple limit blocks 10 are located inside the two limit plates 8 respectively.

[0035] The main function of the multiple card slots 9 is to cooperate with the multiple limit blocks 10 to integrate and plan the fiber optic lines, maintain a neat appearance, and facilitate subsequent inspection and maintenance.

[0036] There are four studs 11 and four springs 12, with the four studs 11 and four springs 12 located in the middle of the four support plates 5 respectively.

[0037] The main function of the four springs 12 is to limit the interface of the limiting plate 8 while maintaining a certain stability by sleeved on the outside of the four studs 11, so as to prevent large shaking.

[0038] Working principle and usage process of this utility model:

[0039] First, a groove 6 is provided inside the support plate 5, and a slider 7 is slidably connected inside the groove 6. A limiting plate 8 is fixedly installed on the side of the slider 7 away from the groove 6. At the same time, a slot 9 is provided inside the limiting plate 8, and a limiting block 10 is fixedly installed inside the slot 9. When it is necessary to install the optical fiber, the optical fiber is first inserted from inside the limiting plate 8 into the slot 9. At the same time, the limiting block 10 will limit and squeeze the line to prevent the optical fiber line from falling off. Meanwhile, the limiting plate 8 is installed behind the multiplexer 1 through the sliding action of the slider 7 and the groove 6. Then, the interface of the optical fiber is plugged into the corresponding first port 2 and second port 3 respectively, so that the optical fiber line is organized and the situation of too many lines causing disorder is prevented.

[0040] Secondly, since a stud 11 is inserted inside the limiting plate 8, and a spring 12 is sleeved on the outside of the stud 11, and a nut 13 is engaged on the side of the stud 11 away from the spring 12, when the fiber optic interface is inserted into the first port 2 and the second port 3, the stud 11 is located in the middle of the limiting plate 8 and the connecting plate 4, so the stud 11 and the nut 13 are engaged. At this time, the spring 12 retracts, so the limiting plate 8 is squeezed and the distance between it and the first port 2 and the second port 3 is shortened. At the same time, since the diameter of the slot 9 is small, the limiting plate 8 will squeeze and limit the interface after contacting the fiber optic interface, preventing the fiber optic interface from becoming loose and causing unstable connection after long-term use.

[0041] Finally, since a dustproof plate 17 is fixedly installed at the rear of the multiplexer 1, and dustproof holes 18 are provided inside the dustproof plate 17, and there are multiple dustproof holes 18, all of which are located above the first port 2 and the second port 3, the multiple dustproof holes 18 can prevent a lot of dust from falling into the surface of the first port 2 and the second port 3 after long-term use, which may cause unstable fiber optic connection.
