Description

Technical Field

[0001] This utility model belongs to the technical field of underground optical cable junction boxes, specifically a jumper for a liftable, waterproof underground optical cable junction box. Background Technology

[0002] An optical fiber junction box is a device that provides termination and patching for backbone and distribution layer optical cables. After the optical cable enters the junction box, it is fixed, terminated, and distributed. Patch cords are then used to connect the backbone and distribution layer optical cables. However, most existing optical fiber junction boxes are installed outdoors, and these are susceptible to vandalism, which can cause network communication interruptions. Therefore, to prevent vandalism, they are often installed underground. However, underground installation requires manual climbing for maintenance and repair, which is inconvenient and reduces the efficiency of maintenance, increasing the labor intensity of workers.

[0003] Meanwhile, a type of underground optical cable junction box with a lifting and waterproof function, disclosed in CN220933250U, is described. It includes a box body, a lifting assembly, an optical cable installation assembly, a door, a handle, and a water outlet pipe. The bottom of the box body is movably connected to a lifting assembly for lifting the box body. Inside the box body is an optical cable installation assembly for fixing the optical cable. The front of the box body is movably connected to a door, and the front surface of the door is provided with a handle. The lifting assembly includes a base, a telescopic cylinder, a water tank, a water collection hopper, and a cooling fan. The bottom of the box body has a base, and the front surface of the base has heat dissipation holes. The optical cable installation assembly includes a fixing plate, a fixing groove, a coiling block, a coiling plate, a coiling roller, a coiling buckle, a heat dissipation plate, a fixing frame, a coiling wheel, and a cable clamping plate. A fixing plate is provided on the right side wall inside the box body, and several fixing grooves are equidistantly arranged on the left side wall of the fixing plate.

[0004] The aforementioned type of liftable, waterproof, underground optical cable junction box is relatively cumbersome to install and difficult to maintain. Water can easily get in through the ventilation holes, which can damage the jumpers. The jumpers are not well protected, and when the box is raised, the external jumpers are easily damaged and need to be replaced before the box can be used again, which increases maintenance time and costs.

[0005] Therefore, a jumper cable for a waterproof, liftable underground optical cable junction box is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a jumper for a liftable, waterproof, underground optical cable junction box, which has the advantages of protecting the jumper, preventing water leakage, and facilitating maintenance.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a jumper for a waterproof, liftable underground optical cable junction box, comprising a junction box body, an electrical box door on the left end face of the junction box body, a small window inside the electrical box door, a door handle in the middle of the left side of the electrical box door, a collection block fixedly mounted on the upper end face of the junction box body, a cavity fixedly mounted inside the collection block, square slots on both the left and right sides of the cavity, a second lifting column slidingly mounted inside the cavity, a rain cover fixedly mounted on the upper end face of the second lifting column, a wire pressing plate fixedly mounted on the right end face of the rain cover, a first support block fixedly mounted on the right end face of the collection block, a jumper groove fixedly mounted on the upper end face of the first support block, and a jumper wire inside the jumper groove.

[0008] Preferably, a lifting column is fixedly provided on the middle of the right side of the upper end face of the junction box body, a protective plate is fixedly provided on the upper end face of the lifting column, and a jumper wire passes through the protective plate. A rubber sleeve is provided on the right end face of the protective plate.

[0009] By adopting the above technical solution, the protective plate with jumper wires can be raised and lowered using the lifting column one, without pulling or damaging the jumper wires.

[0010] Preferably, the lower end face of the pressure plate is provided with a pressure groove, and magnetic suction grooves are provided on the front and rear sides of the pressure groove.

[0011] By adopting the above technical solution, the jumper wires will not be pressed when the pressure plate descends due to the pressure groove, allowing the jumper wires to be used normally without replacement. The magnetic groove allows for faster alignment and installation.

[0012] Preferably, a second support block is fixedly provided on the lower inner surface of the junction box, and a water-absorbing plate is provided on the upper surface of the second support block.

[0013] By adopting the above technical solution, the water absorption plate can absorb the moisture inside the junction box, which can reduce the corrosion of the jumper wires caused by excessive water.

[0014] Preferably, a base is fixedly provided on the lower end face of the junction box, and the base is made of cement.

[0015] By adopting the above technical solution, the base can provide a solid support for the stability of the junction box and also prevent water erosion.

[0016] Preferably, the inside of the collecting block is provided with a waterproof ring, and magnetic blocks are provided on both the front and rear sides of the jumper groove.

[0017] By adopting the above technical solution, the waterproof ring can better isolate water from the outside and reduce the amount of water entering the interior of the junction box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through the collection block, lifting column, rain cover, and waterproof ring, makes the jumper cable more flexible and convenient, prevents rainwater from damaging the jumper cable, and protects the jumper cable with the protective plate and rubber sleeve, so that the jumper cable can be used for a longer time and reduces external damage to the jumper cable.

[0020] 2. This utility model uses a water-absorbing plate to absorb moisture inside the junction box, which can reduce the corrosion of jumpers caused by excessive water inside the junction box. The water-absorbing plate can be easily disassembled and installed using the second support block, preventing the water-absorbing plate from corroding the bottom of the junction box.
