Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical cable junction box technology, and in particular to an outdoor optical cable junction box. Background Technology
[0002] Outdoor fiber optic junction boxes, as key nodes in fiber optic communication networks, are primarily used for fiber optic cable termination, patching, and distribution, undertaking the physical connection and protection functions for optical signal transmission. Their design must balance environmental adaptability, structural stability, and ease of operation. They typically employ waterproof, dustproof, and corrosion-resistant sealed shells, and are equipped with lightning protection and UV resistance measures to cope with complex and variable outdoor weather conditions. Internally, modular design integrates fiber optic splicing, storage, splitting, and adapter installation, supporting high-density fiber optic access. They also feature identification systems and redundant space for easy maintenance and expansion. With the development of 5G and all-optical networks, outdoor junction boxes are evolving towards miniaturization and intelligence. Some models have integrated environmental monitoring sensors and remote management interfaces, contributing to improved network operation and maintenance efficiency.
[0003] Outdoor fiber optic junction boxes, due to long-term exposure to the natural environment, may experience gradual deterioration in their sealing performance, mechanical structure, and fiber optic connection status due to temperature changes, humidity corrosion, or external impacts. Regular maintenance is therefore crucial for ensuring stable network operation. Maintenance typically includes checking the box's sealing (e.g., door seal aging, lock reliability), testing internal fiber optic splice attenuation, cleaning adapters and verifying insertion loss, and testing the resistance of lightning protection grounding devices. Furthermore, it is essential to check whether the internal space of the box is congested with fiber optic cables causing excessive bending radii or damage from insects and rodents. Standardized maintenance procedures can identify potential faults early, extending equipment lifespan and providing fundamental data support for network expansion or technology upgrades. In modern operations and maintenance, the combination of portable testing tools and digital management platforms is continuously improving maintenance efficiency and accuracy.
[0004] Patent document CN213843623U discloses a rainproof outdoor optical cable junction box, including a junction box body, a rainproof mechanism at the top of the junction box body, a base fixed to the bottom of the junction box body, support legs fixed at the four corners of the base, and symmetrically arranged auxiliary support leg mechanisms installed on the side walls of the base. The rainproof mechanism includes a support plate, symmetrically arranged support rods fixed to the top of the support plate, and a V-shaped plate fixed to the top of the support rods. Multiple drainage grooves are formed on the upper surface of the V-shaped plate. Water collection troughs are formed around the edges of the top of the support plate, with the edges of the V-shaped plate directly above the water collection troughs. L-shaped drainage pipes are fixed around the bottom of the support plate, with the top of the vertical section of the L-shaped drainage pipe connected to the bottom of the water collection trough, and the horizontal section of the L-shaped drainage pipe located below the base and extending away from the base. This design collects rainwater in the water collection trough and discharges it outwards, preventing rainwater from splashing onto the surface of the optical cable junction box and improving its rainproof performance.
[0005] As in the prior art of the aforementioned patent, the rainproof mechanism relies on a V-shaped plate to block rain from the device and uses an L-shaped drainage pipe to divert rainwater. However, this method occupies a lot of space, which is equivalent to building a house-shaped rainproof device outside the optical cable junction box. This method is not only costly, but also occupies too much public resources in the outdoor environment. Utility Model Content
[0006] The purpose of this utility model is to provide an outdoor optical cable junction box to solve the above-mentioned shortcomings in the prior art.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: an outdoor optical cable junction box, comprising a junction box body and a base fixedly installed on the hinged box body, an optical cable junction device body fixedly installed inside the junction box body, a door hingedly installed on the junction box body, a fixed seat fixedly installed at the top of the hinged box body, a storage groove opened at the top of the fixed seat, a rainproof component provided inside the storage groove, the rainproof component comprising an inclined plate and a rainproof plate, a second hinge component provided between the inclined plate and the fixed seat, and a first hinge component provided between the inclined plate and the rainproof plate.
[0008] As a further description of the above technical solution: the second hinge assembly includes two first hinges, each of which is threaded with a first bolt, and a first pivot is rotatably mounted between the two first hinges. The two first hinges are respectively fixedly connected to the top edge of the fixed base and the edge of the inclined plate by the first bolts.
[0009] As a further description of the above technical solution: a support block is fixedly installed on the top of the fixed base.
[0010] As a further description of the above technical solution: the first hinge assembly includes a second hinge and a third hinge, a second pivot is rotatably connected between the second hinge and the third hinge, one and two threaded holes are respectively opened on the second hinge and the third hinge, and a second bolt is threadedly installed on the threaded hole. The second hinge and the third hinge are respectively fixedly connected to the rain shield and the inclined plate by the second bolt, and the two sets of threaded holes opened on the second hinge and the third hinge are staggered.
[0011] As a further description of the above technical solution: the edges of the rain shield are all set as bevels.
[0012] As a further description of the above technical solution: the bottom wall of the storage tank is set as a slope, and a water outlet groove is opened on the side wall of the storage tank near the slope in the direction of inclination.
[0013] This utility model provides an outdoor optical cable junction box. It has the following advantages: when the box door is opened, the rain shield can protect the front of the junction box and the staff from rain. Because the joint between the inclined plate and the rain shield can be relatively tight, and a sealing rubber material can be used at the joint to increase the seal, rainwater will not be able to seep through the gaps. Furthermore, after rainwater hits the inclined plate, it can enter the storage groove and then flow out through the drainage channel at the bottom of the storage groove, preventing excessive water accumulation. This device achieves a rain-shielding function, and when not in use, the rain-shielding components can be stored inside the storage groove.
[0014] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.
[0015] This application provides an overview of various implementations or examples of the technology described in this disclosure, and is not a full disclosure of the entire scope or all features of the disclosed technology. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figure 1-10An outdoor optical cable junction box includes a junction box body 1 and a base 3 fixedly installed on the hinged junction box body. An optical cable junction device body 11 is fixedly installed inside the junction box body 1. A door 2 is hinged to the junction box body 1. A fixing seat 4 is fixedly installed at the top of the hinged junction box body. A storage groove 401 is provided at the top of the fixing seat 4. A rainproof assembly is provided inside the storage groove 401. The rainproof assembly includes a sloping plate 5 and a rainproof panel 6. A second hinge assembly 9 is provided between the sloping plate 5 and the fixing seat 4, and a first hinge assembly 8 is provided between the sloping plate 5 and the rainproof panel 6. In rainy weather, when workers inspect the interior of the junction box body 1, the sloping plate 5 in the storage groove 401 is flipped upwards via the second hinge assembly 9. After the sloping plate 5 is flipped to a certain position, the support block 10 can support the sloping plate 5. The rain shield 6 on the rear side of the inclined plate 5 is then flipped forward via the first hinge assembly 8. After the rain shield 6 rotates to be parallel to the ground, the edges of the rain shield 6 and the inclined plate 5 are joined and limited, thereby enabling the rain shield 6 to unfold. After the box door 2 is opened, the rain shield 6 can protect the front of the transfer box 1 and the staff from rain. Since the joint between the inclined plate 5 and the rain shield 6 can be relatively tight, and a sealing rubber material can be set at the joint to increase the sealing performance, no rainwater can seep through the gaps and flow down. After the rainwater falls on the inclined plate 5, it can enter the storage groove 401 and then flow out from the water outlet 12 through the slope 13 at the bottom of the storage groove 401, without causing a large accumulation of rainwater. The above device can achieve the rain shield function, and when the device is not in use, the rain shield assembly can be stored inside the storage groove 401.
[0030] As a preferred embodiment, the second hinge assembly 9 includes two first hinges 14, each of which is threaded with a first bolt 16. A first pivot 15 is rotatably mounted between the two first hinges 14. The two first hinges 14 are fixedly connected to the top edge of the fixed base 4 and the edge of the inclined plate 5 respectively by the first bolts 16. The two first hinges 14 are fixed to the fixed base 4 and the edge of the inclined plate 5 by the first bolts 16, thereby enabling the inclined plate 5 to be flipped upwards and to rotate stably at the edge of the fixed base 4.
[0031] As a preferred technical solution in this embodiment, a support block 10 is fixedly installed on the top of the fixed base 4; when the inclined plate 5 is rotated upward by 135 degrees through the second hinge assembly 9, the inclined plate 5 can overlap the inclined surface 7 of the support block 10 under the action of gravity and remain stable.
[0032] As a preferred embodiment, the first hinge assembly 8 includes a second hinge 18 and a third hinge 19. A second pivot 17 is rotatably connected between the second hinge 18 and the third hinge 19. One and two threaded holes 21 are respectively opened on the second hinge 18 and the third hinge 19. A second bolt 20 is threaded onto the threaded hole 21. The second hinge 18 and the third hinge 19 are fixedly connected to the rain shield 6 and the inclined plate 5 respectively by the second bolt 20. The two sets of threaded holes 21 on the second hinge 18 and the third hinge 19 are staggered. Since the inclined plate 5 and the rain shield 6 need to be joined together, in order to ensure that there is not much interference when the first hinge 14 and the third hinge 19 come into contact, the second bolts 20 on the first hinge 14 and the third hinge 19 are staggered to prevent the gap from being too large when the first hinge 14 and the third hinge 19 drive the inclined plate 5 and the rain shield 6 to overlap, thus avoiding affecting storage.
[0033] As a preferred technical solution in this embodiment, the edges of the rain shield 6 are all set as inclined surfaces 7; the setting of the inclined surfaces 7 can guide rainwater, so that the rainwater flows outward along the inclined surfaces 7.
[0034] As a preferred technical solution of this embodiment, the bottom wall of the storage trough 401 is set as a slope 13, and a water outlet trough 12 is opened on the side wall of the storage trough 401 near the inclined direction of the slope 13. The slope 13 is set to prevent water accumulation. Through the slope 13, the water can be drained out of the interior of the storage trough 401 through the water outlet trough 12.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
