Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, specifically to an optical junction box with a grounding structure. Background Technology

[0002] Fiber optic junction boxes are outdoor connection devices. Their most fundamental requirement is to withstand drastic climate changes and harsh working environments. They must be waterproof, dustproof, insect and rodent resistant, and impact-resistant. They must be able to withstand relatively harsh external environments. Therefore, the outer side of the box has high requirements for waterproofing, moisture-proofing, dustproofing, impact resistance, and insect and rodent protection; while the inner side has very high requirements for temperature and humidity control.

[0003] According to a public announcement (Announcement No.: CN214099943U) of a grounding structure and grounding metal component for an optical distribution box, the above application includes a grounding lead-in line for connecting the grounding equipment of the optical distribution box, a first grounding body for connecting the grounding lead-in line, and a second grounding body for connecting the first grounding body; the grounding resistance of the grounding lead-in line grounded through the first grounding body and the second grounding body is ≤10Ω; the second grounding body is a vertical grounding body buried below the ground, and the top of the vertical grounding body is ≥0.7m from the ground.

[0004] However, in actual use, rainwater may flow between the cabinet and the ground during rain, forming a current path. This is especially true when the grounding wire is not securely connected or the cabinet material itself is conductive. This may cause current leakage and unexpected current backflow into the cabinet, increasing the risk of electric shock. In view of this, we propose an optical junction box with a grounding structure. Utility Model Content

[0005] The purpose of this invention is to provide an optical junction box with a grounding structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical junction box with a grounding structure, comprising an optical junction box body, a grounding wire fixedly connected to the bottom of the optical junction box body, and an insulating component provided at the bottom of the optical junction box body, the insulating component comprising:

[0007] A waterproof arc plate is fixedly connected to the bottom end face of the optical junction box body;

[0008] The base has a mounting groove at its bottom, and the base is inserted into the plug, which is fixedly connected to the bottom end face of the base.

[0009] Connecting rod one, a crossbar is fixedly connected to the inner wall of the insert block, connecting rod one is rotatably connected to crossbar one, connecting rod one is sleeved with a rotating shaft, the rotating shaft is sleeved with connecting rod two, and connecting rod two is hinged to the inner bottom surface of the base;

[0010] The motor is fixedly connected to the side wall of the mounting block, which is fixedly connected to the side wall of the rotating shaft. The output end of the motor is fixedly connected to the threaded rod, which is threadedly connected to the mounting block.

[0011] Preferably, the optical junction box body is sleeved with a rubber ring, the rubber ring is sleeved with a grounding wire, and the grounding wire is inserted into the ground.

[0012] Preferably, a rubber sleeve is fixedly connected to the outer wall of the insert block, and the outer wall of the rubber sleeve is movably connected to the base.

[0013] Preferably, a connector is fixedly connected to the side wall of the base, and a threaded hole is provided on the top of the connector. The base is then fixedly connected to the bottom surface through the connector on the base.

[0014] Preferably, there are two sets of connecting rod one and connecting rod two, and the two sets of connecting rod one and connecting rod two are symmetrically arranged on the top end face of the base.

[0015] Preferably, the number of waterproof arc plates is set in several groups, and the several groups of waterproof arc plates are equally spaced on the bottom end face of the optical junction box body. Rainwater drips down through the outer edge of the waterproof arc plates, thereby preventing rainwater from entering the gaps between the waterproof arc plates and thus ensuring electrical conductivity.

[0016] Compared with the prior art, the present invention provides an optical junction box with a grounding structure, which has the following advantages:

[0017] 1. This optical distribution box with a grounding structure, through its insulating components, prevents rainwater from entering through the gaps between the waterproof arc plates, thus preventing it from conducting electricity. This prevents rainwater from forming a current path during rain, reducing the risk of current leakage, avoiding current backflow into the optical distribution box body, reducing the risk of electric shock, increasing the insulation performance of the optical distribution box body, preventing external moisture from affecting the normal operation of the equipment, extending the service life of the equipment, and raising the height of the optical distribution box body to prevent rainwater from directly soaking into the bottom of the equipment, reducing the risk of rainwater erosion and damage to the equipment, and helping to maintain the normal operation of the equipment.

[0018] 2. This optical junction box with a grounding structure isolates the electrical connection between the optical junction box body and the grounding wire through the rubber ring and rubber sleeve, providing insulation protection and reducing the risk of leakage and electric shock. The rubber sleeve has a certain shock absorption effect, which can reduce the impact of the plug block on the base when the optical junction box body is lowered, thus reducing the impact on the optical junction box body and internal components.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: an optical junction box with a grounding structure, including an optical junction box body 1, a grounding wire 2 fixedly connected to the bottom of the optical junction box body 1, and an insulating component 3 provided at the bottom of the optical junction box body 1. The insulating component 3 includes a waterproof arc plate 301, a base 302, a plug block 303, a crossbar 304, a connecting rod 1 305, a connecting rod 2 306, a rotating shaft 307, a mounting block 308, a motor 309, and a threaded rod 310.

[0026] In one embodiment of this utility model, a waterproof arc plate 301 is fixedly connected to the bottom end face of the optical junction box body 1. Several sets of waterproof arc plates 301 are arranged at equal intervals on the bottom end face of the optical junction box body 1. Rainwater drips down through the outer edge of the waterproof arc plate 301, thereby preventing rainwater from entering the gaps between the waterproof arc plates 301 and thus conducting electricity. The bottom of the base 302 is provided with an installation groove, and a connector 6 is fixedly connected to the side wall of the base 302. The top of the connector 6 is provided with a threaded hole. The base 302 is fixedly connected to the bottom surface through the connector 6 on the base 302. The base 302 is inserted into the plug 303, and the plug 303 is fixedly connected to the bottom end face of the base 302.

[0027] A crossbar 304 is fixedly connected to the inner wall of the insert block 303. A connecting rod 305 is rotatably connected to the crossbar 304. The connecting rod 305 is sleeved with the rotating shaft 307. The rotating shaft 307 is sleeved with the connecting rod 306. The connecting rod 306 is hinged to the inner bottom surface of the base 302. There are two sets of connecting rods 305 and 306. The two sets of connecting rods 305 and 306 are symmetrically arranged on the top end face of the base 302.

[0028] The motor 309 is fixedly connected to the side wall of the mounting block 308, the mounting block 308 is fixedly connected to the side wall of the rotating shaft 307, the output end of the motor 309 is fixedly connected to the threaded rod 310, and the threaded rod 310 is threadedly connected to the mounting block 308.

[0029] The base 302 and the plug 303 separate the optical junction box body 1 from the ground. Rainwater drips down through the outer edge of the waterproof arc plate 301, thus preventing rainwater from entering the gaps between the waterproof arc plates 301 and conducting electricity. This prevents rainwater from forming a current path during rain, reducing the risk of current leakage and preventing current from flowing back to the optical junction box body 1, thereby reducing the risk of electric shock. At the same time, the waterproof arc plate 301 increases the insulation performance of the optical junction box body 1, preventing moisture from the external environment from affecting the normal operation of the equipment and extending the service life of the equipment.

[0030] When there is a lot of rainwater on the bottom surface, the motor 309 drives the threaded rod 310 to rotate, which in turn causes the two mounting blocks 308 to move towards each other. The movement of the mounting blocks 308 towards each other causes the included angle between the first connecting rod 305 and the second connecting rod 306 to gradually increase until they are on the same line, thereby raising the height of the optical junction box body 1, preventing rainwater from directly soaking into the bottom of the equipment, reducing the risk of rainwater erosion and damage to the equipment, and helping to maintain the normal operation of the equipment.

[0031] In addition, the optical junction box body 1 is sleeved with the rubber ring 5, the rubber ring 5 is sleeved with the grounding wire 2, the grounding wire 2 is inserted into the ground, and the outer wall of the plug 303 is fixedly connected with a rubber sleeve 4. The outer wall of the rubber sleeve 4 is movably connected with the base 302, which can isolate the electrical connection between the optical junction box body 1 and the grounding wire 2, provide insulation protection, reduce the risk of leakage and electric shock. Through the setting of the rubber sleeve 4, the rubber material has a certain shock absorption effect, which can reduce the impact of the plug 303 on the base 302 when the optical junction box body 1 is lowered, and protect the equipment from vibration damage.

[0032] In this invention, during use, the base 302 and the insert block 303 separate the optical junction box body 1 from the ground. Rainwater drips down through the outer edge of the waterproof arc plate 301, thus preventing rainwater from entering the gaps between the waterproof arc plates 301 and thus ensuring electrical conductivity. This prevents rainwater from forming a current path during rain and reduces the risk of current leakage. When there is a lot of rainwater on the bottom surface, the motor 309 drives the threaded rod 310 to rotate, which causes the two mounting blocks 308 to move towards each other. The opposite movement of the mounting blocks 308 causes the included angle between the first connecting rod 305 and the second connecting rod 306 to gradually increase until they are on the same line, thereby raising the height of the optical junction box body 1 and preventing rainwater from directly soaking the bottom of the equipment, thus reducing the risk of rainwater erosion and damage to the equipment.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
