Description

Technical Field

[0001] This utility model relates to the field of optical cable line distribution technology, specifically an optical cable line distribution device. Background Technology

[0002] Optical fiber cable distribution devices are key auxiliary equipment in communication transmission systems. They are used to centrally collect, branch, distribute, and fix multiple optical cables to adapt to different application scenarios such as equipment rooms and outdoor poles. Their core functions are to prevent optical cables from becoming tangled or compressed, ensure signal transmission stability, and facilitate subsequent line inspection and maintenance. They are a fundamental component supporting the efficient operation of communication networks.

[0003] Existing fiber optic cable distribution devices can already achieve basic distribution functions. Their simple partitioning structure reduces cable tangling, and some devices are equipped with basic fixing components, improving the neatness of the cable layout and reducing initial maintenance difficulty, meeting the needs of low-load and simple scenarios. However, existing devices still have significant shortcomings: First, their moisture resistance in outdoor environments is weak; dampness easily corrodes internal components, accelerating aging and affecting the stability of fiber optic transmission. Second, the assembly and disassembly process is cumbersome, increasing the difficulty of maintenance and severely limiting the efficiency of future expansion with new fiber optic cables. Therefore, we provide a fiber optic cable distribution device to solve these problems. Utility Model Content

[0028] 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.

[0029] like Figure 1-7 As shown, this utility model provides a technical solution: an optical cable distribution device, including an installation plate 1 for fixing to external structures such as walls and brackets and providing a stable installation foundation for the entire device; a moisture-proof mechanism 2 is provided above the installation plate 1 for isolating external moisture and protecting the optical cable and core components inside the device; a snap-fit ​​mechanism 3 is provided on the moisture-proof mechanism 2 for realizing the quick assembly and disassembly of the components of the moisture-proof mechanism 2 and facilitating later maintenance and repair.

[0030] The moisture-proof mechanism 2 forms a double moisture-proof protection through a sealing structure that can seal gaps and a moisture-absorbing structure that can absorb internal moisture, effectively preventing moisture intrusion from causing problems such as aging of the optical cable insulation layer and corrosion of components. The snap-fit ​​mechanism 3, through a plug-in structure that can be precisely positioned and a snap-fit ​​structure that can be automatically locked, can complete the disassembly and assembly operations without the need for tools such as screwdrivers and wrenches, greatly improving the efficiency of device installation and maintenance.

[0031] The moisture-proof mechanism 2 includes two symmetrical sealing frames 201 that can be enclosed to form a closed protective space. The lower surface of the lower sealing frame 201 is fixedly connected to the upper surface of the mounting plate 1 to ensure that the moisture-proof mechanism 2 is stably connected to the installation foundation. On the side of the two sealing frames 201 that are close to each other, there are multiple cable trays 202 for optical cables to be threaded through and for different optical cables to be sorted and organized. The two sets of cable trays 202 are arranged in pairs to form multiple independent cable holes, which can not only prevent multiple optical cables from getting tangled and worn during the threading process, but also facilitate the quick identification of the direction of different optical cables in the later stage, and improve the regularity of line distribution.

[0032] Both sealing frames 201 have sealing strips 203, preferably made of elastic rubber, fixedly connected to their adjacent sides to seal the gaps at the edges of the wire passage 202 and enhance the sealing performance. These strips can fit tightly when the upper and lower sealing frames 201 are closed, preventing external moisture from entering through the gaps. Both sealing strips 203 are fixedly connected to the inner edges of multiple wire passages 202 on the same side, ensuring that the gaps in each wire passage 202 are effectively covered. The inner wall of the lower sealing frame 201 has a perforated plate 20 fixedly connected to it to separate the drying ball from the main body 205 without affecting the flow of moisture. The plate 4 has multiple fine holes, allowing moisture inside the device to easily penetrate to the drying ball. A storage chamber for storing the drying ball is formed between the perforated plate 204 and the inner bottom wall of the lower sealing frame 201. The storage chamber contains drying balls such as silica gel desiccant that can absorb moisture. After absorbing moisture, they can be replaced periodically. The main body 205 for realizing the distribution and transfer functions of optical cable lines is fixedly installed on the upper surface of the perforated plate 204. Through the cooperation of the perforated plate 204 and the drying ball, the dry environment of the space where the main body 205 is located can be maintained continuously, extending the service life of the main body 205.

[0033] The snap-fit ​​mechanism 3 includes two symmetrical fixing plates 301 for connecting the upper sealing frame 201 and the plug rod 302, and two symmetrical plug-fit plates 304 for positioning the plug rod 302. The sides of the two fixing plates 301 that are close to each other are fixedly connected to the outer surface of the upper sealing frame 201, which can evenly transfer the force of the plug rod 302 to the upper sealing frame 201 and avoid structural deformation caused by local stress. The lower surfaces of the two fixing plates 301 are fixedly connected to two symmetrical plug rods 302 for inserting into the plug groove 305 for initial positioning. The bottom of the two sets of plug rods 302 that are close to each other are provided with a snap-fit ​​groove 303 for locking and fixing with the snap-fit ​​rod 309. The groove size of the snap-fit ​​groove 303 is adapted to the end of the snap-fit ​​rod 309 to ensure that it is not easy to loosen after snap-fit.

[0034] The two plug-in plates 304 are fixedly connected to the outer surface of the lower sealing frame 201 on their adjacent sides, providing a stable mounting carrier for the plug-in slots 305. The upper surfaces of the two plug-in plates 304 each have two symmetrical plug-in slots 305 for accommodating the plug-in rods 302. The inner wall of the plug-in slots 305 fits against the outer wall of the plug-in rods 302, which can limit the lateral displacement of the plug-in rods 302 and ensure that the upper and lower sealing frames 201 are aligned and closed. The inner sidewalls of the two sets of plug-in slots 305 are respectively inserted into the bottom ends of the two sets of plug-in rods 302. The bottom of the two sets of plug-in slots 305 on their adjacent sides are provided with a first sliding groove 306 to provide sliding space for the snap-fit ​​rods 309. The length of the first sliding groove 306 is adapted to the sliding stroke of the snap-fit ​​rods 309 to ensure that the snap-fit ​​rods 309 can be fully extended or retracted.

[0035] Both sets of first sliding grooves 306 have elastic elements 308 (preferably compression springs) fixedly connected to their respective sidewalls on the left and right sides, which provide a restoring force for the locking rods 309. In the initial state, these elements can push the locking rods 309 out of the first sliding grooves 306. Both sets of elastic elements 308 have locking rods 309 fixedly connected to their respective ends on the left and right sides, which are far apart from each other. These locking rods 309 are used to insert into the locking slots 303 to achieve locking. The outer surfaces of the two sets of locking rods 309 are slidably connected to the inner sidewalls of the two sets of first sliding grooves 306, ensuring that the locking rods 309 slide smoothly without jamming. Both sets of locking rods 309 have a ramp surface 310 on their respective ends on the left and right sides, which facilitates the automatic squeezing of the locking rods 309 when the insertion rod 302 is inserted. When the insertion rod 302 is inserted downwards, its bottom end can squeeze the locking rod 309 along the ramp surface 310, causing the locking rod 309 to automatically retract into the first sliding groove 306 without manual operation, thus improving the ease of installation.

[0036] Two sets of locking rods 309 are inserted into the interiors of two sets of locking slots 303 at their far ends, achieving automatic locking and fixing of the upper and lower sealing frames 201. Two plug-in plates 304 each have a second sliding groove 307 on their far sides for sliding the push-pull rod 311 and communicating with the first sliding groove 306. The inner walls of the two second sliding grooves 307 are slidably connected to two symmetrical push-pull rods 311 for disengaging the locking rods 309 from the locking slots 303. The ends of the two push-pull rods 311 near the moisture-proof mechanism 2 are fixedly connected to the outer surfaces of the two sets of locking rods 309. When disassembly is required, pushing the push-pull rods 311 towards the center of the device compresses the elastic element 308 and disengages the locking rod 309 from the locking slot 303. Then, lifting the upper sealing frame 201 completes the disassembly. The operation is simple and quick.

[0037] Working principle: When installing the optical cable distribution device, the lower sealing frame 201 is first fixedly connected to the mounting plate 1 through its lower surface to complete the basic positioning of the device; then, the plug-in rod 302 below the fixing plate 301 corresponding to the upper sealing frame 201 is aligned with the plug-in groove 305 on the plug-in plate 304 on the outer surface of the lower sealing frame 201 and inserted. During the insertion process, the bottom of the plug-in rod 302 presses against the slope surface 310 of the locking rod 309, causing the locking rod 309 to slide along the first sliding groove 306 towards the elastic member 308, and simultaneously compressing the elastic member 308; when the plug-in rod 302 is fully inserted into the plug-in groove 305, the elastic member 308 resets and pushes the locking rod 309 to slide in the opposite direction along the first sliding groove 306 until the end of the locking rod 309 away from the elastic member 308 is inserted into the slot 303 of the plug-in rod 302, thereby achieving rapid fixation of the upper and lower sealing frames 201 and completing the device assembly. In use, the optical cable passes through the corresponding through holes formed by the two sets of cable trays 202, and the sealing strip 203 seals the edges of the cable trays 202. At the same time, in the storage chamber formed by the perforated plate 204 and the inner bottom wall of the lower sealing frame 201, the drying ball absorbs moisture from the inside of the device through the holes of the perforated plate 204, preventing the main body 205 located on the perforated plate 204 from getting damp. When disassembly and maintenance are required, push the push-pull rod 311 in the second sliding groove 307 on the outside of the plug-in plate 304. The push-pull rod 311 drives the snap-fit ​​rod 309 to compress the elastic element 308 and disengage it from the snap-fit ​​groove 303, allowing the upper sealing frame 201 to be removed upwards for quick disassembly.
