Description

Technical Field

[0001] This utility model relates to the field of cable junction box technology, and in particular to a cable junction box. Background Technology

[0002] In modern power transmission and distribution systems, cable junction boxes serve as crucial hubs connecting cables to user terminals, undertaking vital functions such as power distribution, cable switching, and fault isolation. Their performance directly impacts the stability and security of the power system. With the advancement of urban power grid transformation and upgrading, and the construction of smart grids, higher demands are placed on the ease of installation and reliability of cable junction boxes. In particular, the two core technical aspects of cable fixing and box sealing have become critical to ensuring the efficient operation of the equipment.

[0003] Traditional cable junction boxes typically employ a bolt-fastened clamp structure for cable fixing. This structure involves manually tightening each bolt with a wrench to secure the cable to the clamp. The underlying principle is that the helical transmission of the bolts and nuts converts rotational force into pressure on the cable from the clamp. When cable fixing is required, the operator must adjust the bolts at multiple points around the junction box, repeatedly testing and adjusting the tightness of different bolts until the clamp and cable are tightly fitted, thus achieving cable fixation.

[0004] However, traditional junction boxes, using bolt-fastened clamp structures, require manual adjustment of multiple bolts one by one. This cumbersome process makes it difficult to ensure even pressure distribution across the clamps, easily leading to excessive localized stress on the cables or insecure fixation. During long-term operation, factors such as cable thermal expansion and contraction and environmental vibration can cause unevenly secured cables to easily sway and shift. This not only increases the risk of cable sheath wear but may also cause loose electrical connections, affecting power transmission stability and even leading to short circuits and other safety accidents. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable junction box, which aims to improve the problem that traditional junction boxes, which use bolt-fastened clamping plate structures, require manual adjustment of multiple bolts one by one, making the operation cumbersome and making it difficult to ensure uniform pressure distribution on each clamping plate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable junction box, including a shelf, with protective frames fixedly connected to both sides of the outer wall of the shelf, a threaded rod threadedly connected to the inside of the protective frame, a handle fixedly connected to one end of the threaded rod, a clamping plate rotatably connected to the other end of the handle, an elastic pad fixedly connected to the outer wall of the clamping plate, and a linkage component provided on both sides of the outer wall of the clamping plate.

[0007] The linkage assembly includes a first linkage, a turntable, and a second linkage. One end of each of the first and second linkages is rotatably connected to the upper and lower sides of the outer wall of the clamping plate. The other end of each of the first and second linkages is rotatably connected to the turntable, and a rotating shaft is rotatably connected to the center of the turntable.

[0008] Furthermore, a rainproof top plate is fixedly connected to the top of the storage panel, a door is provided on the outer wall of the storage panel, a handle is fixedly connected to the outer wall of the door, and a sealing component is provided inside the door.

[0009] Furthermore, it includes a sliding plate, a limiting plate, and a sealing plate. The sliding plate and the limiting plate are slidably connected inside the door, the sealing plate is fixedly connected to the outer wall of the limiting plate, and a propulsion assembly is provided inside the sliding plate.

[0010] Furthermore, the propulsion assembly includes a slide rod and a spring, one end of the slide rod being fixedly connected to the inside of the sliding plate, and the spring being sleeved on the outer wall of the slide rod.

[0011] Furthermore, the outer wall of the spring is slidably connected to the inside of the door to guide the spring.

[0012] Furthermore, one end of the spring is fixedly connected to the inside of the sliding plate, and the other end of the spring is fixedly connected to the inside of the box door.

[0013] Furthermore, one end of the rotating shaft is fixedly connected inside the protective frame to limit the rotation of the turntable.

[0014] Furthermore, the outer wall of the clamp is slidably connected to the inside of the protective frame.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model achieves efficient and stable adjustment during cable fixing through the design of components such as handles, threaded rods, clamps, connecting rods, and turntables. The threaded engagement between the threaded rod and the protective frame ensures the accuracy of linear movement. The sliding of the clamps, combined with the transmission of the connecting rod, converts linear motion into rotational motion, allowing the clamps on both sides to move synchronously. This not only makes operation convenient but also provides a firm and uniform clamping and fixing of the cable, effectively preventing cable shaking and displacement, and improving the reliability and stability of cable installation.

[0017] 2. In this utility model, when the box door is closed, the sealing plate is tightly fitted under the pushing action of the spring, forming a highly efficient sealing structure, which effectively prevents external rainwater, dust, moisture and other substances from entering the inside of the cable junction box, creating a safe and stable operating environment for the electrical equipment inside the box, reducing the risk of equipment failure caused by external factors, extending the service life of the cable junction box and the internal equipment, and ensuring the safety and continuity of power transmission.

[0030] Specifically, ...

[0031] Working principle: When the cable junction box is needed, first pass the cable through the gap between the two clamps 5. Then, drive the handle 3 to rotate the threaded rod 4 inside the protective frame 2. Due to the threaded engagement between the threaded rod 4 and the protective frame 2, a stable linear movement is ensured when the threaded rod 4 rotates, thereby pushing the clamps 5 to slide along the internal track of the protective frame 2. The movement of the clamps 5 is not just a single movement, but also achieves a more complex linkage effect through the movement of the connecting rod 7 connected to it. When the clamps 5 slide along the internal track of the protective frame 2... When in motion, the part connected to the first connecting rod 7 at one end is subjected to traction force, causing the first end of the first connecting rod 7 to move accordingly. At the same time, the other end of the first connecting rod 7 is connected to the turntable 8. As the first connecting rod 7 moves, it drives the turntable 8 to rotate along the outer wall of the rotating shaft 9, which can convert the motion from linear motion to rotational motion. Then, through the connection between the other end of the turntable 8 and the second connecting rod 10, the rotational motion is converted back into linear motion. The other end of the second connecting rod 10 is connected to the opposite clamping plate 5. Therefore, through the traction of the second connecting rod 10, the synchronous movement of the opposite clamping plate 5 is achieved.

[0032] In addition, when the door 12 is closed, the sealing plates 15 inside the two doors 12 will fit together, and finally, with the push of the spring 17, the two sealing plates 15 can fit tightly together to achieve efficient sealing.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
