Description

Technical Field

[0001] This utility model relates to the field of cable branch box technology, specifically a multifunctional integrated intelligent cable branch box. Background Technology

[0002] Multifunctional integrated intelligent cable distribution boxes are key node devices in power distribution networks. Acting as a smart central hub, they efficiently and reliably distribute main cables from upstream power sources to multiple downstream lines. Their core function lies in integrating traditional branching, protection, monitoring, and fault handling capabilities into a single unit. They can monitor the current, voltage, and other operating status of lines in real time, automatically isolate faulty sections to ensure normal power supply to non-faulty areas, and support remote control and intelligent management. This significantly improves the reliability, flexibility, and automation level of the power distribution network, making it a crucial infrastructure for achieving intelligent upgrades and lean operation and maintenance of the distribution network.

[0003] Existing cable installation technologies for branch boxes generally suffer from several inherent defects. Most fixing structures rely on simple bolt crimping or cable ties, which are difficult to control in terms of clamping force and lack effective self-locking mechanisms. When cables are subjected to external tension, vibration, or their own weight, they are prone to slippage or loosening at the fixing points, leading to increased stress at electrical connection points and potential safety hazards due to unstable connections. Furthermore, traditional rigid clamping methods involve direct friction with the cable surface, which can easily wear down or even cut the cable insulation layer during installation or long-term operation, shortening cable life and potentially causing insulation failures. Existing devices struggle to balance achieving secure fixing with protecting the cable itself, failing to effectively resolve the core contradiction of wear and loosening caused by improper fixing.

[0004] In view of this, we propose a multifunctional integrated intelligent cable branch box. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional integrated intelligent cable branch box, which solves the dual defects of existing cable fixing methods, namely, insecure clamping that is easy to loosen and rigid clamping that is easy to wear down the cable insulation layer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multifunctional integrated intelligent cable branch box includes a branch box body, an internal mounting bracket fixedly connected to the branch box body, and an air switch fixedly connected to the mounting bracket by bolts; it also includes a control component for preventing cable from being pulled and worn during installation and ensuring the stability of the cable after installation; the control component includes a fixing sleeve that penetrates the branch box body and is fixedly connected to the branch box body, a ratchet disk rotatably connected to one end of the fixing sleeve inside the branch box body, a lever fixedly connected to the surface of the ratchet disk away from the fixing sleeve, and a toggle groove fixedly connected to the surface of the ratchet disk near the fixing sleeve; a first fixing plate and a second fixing plate fixedly connected inside the fixing sleeve, a first movable groove and a second movable groove being formed on the surface of the first fixing plate and the second fixing plate being formed on the surface of the second fixing plate.

[0007] Preferably, a linkage plate is fixedly connected inside the fixed sleeve, and the linkage plate has a movable groove inside.

[0008] Preferably, a shaft is fixedly connected to the inner side of the movable groove, the shaft passes through and is rotatably connected to a rotating block, and telescopic rods are fixedly connected to both sides of the rotating block.

[0009] Preferably, the telescopic rods fixedly connected to both sides of the rotating block are all connected to hinge blocks through and slidably, and a push block is inserted into and hinged at the end of the hinge block away from the rotating block.

[0010] Preferably, there are two sets of push blocks, and the two sets of push blocks are located in movable slot one and movable slot two respectively. At the same time, an arc-shaped clamping block is fixedly connected to one end of each set of push blocks near the center of the fixed sleeve.

[0011] Preferably, a linkage rod is fixedly connected to the surface of the push block in the second movable groove, and the end of the linkage rod away from the push block is inserted into the actuation groove.

[0012] Preferably, the bottom of the arc-shaped clamping block fixed to the bottom of the push block in the movable groove is provided with an anti-wear wheel, and the outer side of the fixed sleeve is provided with a pawl, which meshes with the teeth of the ratchet disc.

[0013] By employing the above technical solution, this utility model provides a multifunctional integrated intelligent cable branch box. It possesses at least the following beneficial effects:

[0014] 1. This utility model, through the cooperation of a ratchet disc and a linkage rod, transforms the simple operation of manually rotating a lever into a synchronous clamping force of two sets of arc-shaped clamping blocks on the cable. After the cable is inserted into the fixing sleeve, rotating the lever drives the pushing block to move towards the center, allowing the clamping blocks to stably grip the cable. Its core advantage lies in the introduction of a one-way self-locking mechanism composed of a ratchet and pawl. Once clamped, any force attempting to pull the cable will be transmitted to the ratchet disc through the pushing block and linkage rod, while the pawl immediately locks the ratchet to prevent it from reversing, thus firmly fixing the cable. This mechanical self-locking method effectively resists external pulling, fundamentally preventing the cable from loosening or slipping at the interface due to force, greatly improving the long-term operational stability after installation.

[0015] 2. This utility model achieves secure fixing while protecting the cable itself. The specially designed anti-wear wheel directly contacts the cable surface, transforming the static sliding friction between the cable and the arc-shaped clamp into rolling friction during clamping and subsequent vibration, significantly reducing frictional resistance and wear on the cable insulation surface. This design avoids scratches or indentations on the cable sheath that can occur with traditional fixing methods, effectively extending the cable's service life. The entire clamping process uses a mechanical structure for automatic centering and uniform force application, avoiding stress concentration and ensuring the reliability of the electrical connection. It is particularly suitable for enclosure environments susceptible to vibration or requiring frequent maintenance. Attached Figure Description

[0018] 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.

[0019] A multifunctional integrated intelligent cable branch box, such as Figure 1 - Figure 6 As shown, the system includes a branch box 1, with a mounting bracket 3 fixedly connected inside the branch box 1. An air switch 4 is fixedly connected to the mounting bracket 3 by bolts. It also includes a control component 2 to prevent cable wear during installation and ensure cable stability after installation. The control component 2 includes a fixing sleeve 21 that penetrates the branch box 1 and is fixedly connected to it. A ratchet disc 22 is rotatably connected to one end of the fixing sleeve 21 inside the branch box 1. A lever 23 is fixedly connected to the surface of the ratchet disc 22 away from the fixing sleeve 21, and a lever groove 24 is fixedly connected to the surface of the ratchet disc 22 near the fixing sleeve 21. A first fixing plate 25 and a second fixing plate 26 are fixedly connected inside the fixing sleeve 21. The surface of the first fixing plate 25 has a first movable groove 29, and the surface of the second fixing plate 26 has a second movable groove 210. A linkage plate 27 is fixedly connected inside the fixing sleeve 21, and the linkage plate 27 has a movable groove 211 inside.

[0020] A shaft 212 is fixedly connected to the inner side of the movable groove 211. The shaft 212 passes through and is rotatably connected to a rotating block 213. Telescopic rods 214 are fixedly connected to both sides of the rotating block 213. The telescopic rods 214 fixedly connected to both sides of the rotating block 213 are all slidably connected to hinge blocks 215. A push block 216 is inserted into and hinged to the end of the hinge block 215 away from the rotating block 213. When the cable is pulled externally, it attempts to move within the fixed sleeve 21. However, the clamping force of the arc-shaped clamp 218 is transmitted to the rotating block 213 and the linkage rod 217 through the push block 216. The linkage rod 217 engages with the actuation groove 24 of the ratchet disc 22, and the ratchet disc 22 is locked in one direction by the pawl 220 and cannot be reversed, thus forming a self-locking mechanism that effectively resists the pulling force. If it is necessary to release the cable, simply lift the pawl 220 to disengage from the teeth of the ratchet disc 22, and reverse the lever 23 to drive the push block 216 to reset the arc-shaped clamp 218 and release the cable. The entire control assembly 2, through mechanical linkage and self-locking structure, ensures that the cable is not pulled and worn during installation and maintains long-term stability after installation.

[0021] There are two sets of push blocks 216, located in movable slot 1 29 and movable slot 210 respectively. Each set of push blocks 216 has an arc-shaped clamping block 218 fixedly connected to one end near the center of the fixed sleeve 21. A linkage rod 217 is fixedly connected to the surface of the push block 216 in movable slot 210, with the end of the linkage rod 217 away from the push block 216 inserted into the actuating slot 24. The bottom of the arc-shaped clamping block 218 fixed to the bottom of the push block 216 in movable slot 29 is equipped with an anti-wear wheel 219. A pawl 220 is provided on the outer side of the fixed sleeve 21, engaging with the teeth of the ratchet disc 22. The lever 23 is activated, causing the ratchet disc 22 to rotate. Since the ratchet disc 22 is rotatably connected to the fixed sleeve 21 and has a pulsating groove 24 on its surface, the rotating ratchet disc 22 drives the linkage rod 217 to move laterally through the pulsating groove 24. The linkage rod 217 pushes the push block 216 in the movable groove 210 towards the center of the fixed sleeve 21. The push block 216 is connected to the rotating block 213 through the hinge block 215, and the rotating block 213 is rotatably connected to the movable groove 211 of the linkage plate 27 through the shaft 212. At the same time, the telescopic rods 214 on both sides of the rotating block 213 are respectively connected to two sets of hinges. The connecting block 215 is slidably connected; when the pushing block 216 in the second movable slot 210 is pushed, it forces the rotating block 213 to rotate around the shaft 212 through the hinge block 215, and then drives the pushing block 216 in the first movable slot 29 to move synchronously towards the center through the hinge block 215 on the other side; the arc-shaped clamping blocks 218 at the ends of the two sets of pushing blocks 216 clamp the cable to fix the cable; wherein, the arc-shaped clamping blocks 218 at the bottom of the pushing block 216 in the first movable slot 29 are provided with anti-wear wheels 219, which contact the cable surface when clamping to prevent direct friction damage to the cable.

[0022] In use, the multifunctional integrated intelligent cable branch box of this utility model allows the cable to pass through the fixed sleeve 21 during installation. At this time, the ratchet disc 22 is rotated by manually moving the lever 23. Since the ratchet disc 22 is rotatably connected to the fixed sleeve 21 and has a moving groove 24 on its surface, the rotating ratchet disc 22 drives the linkage rod 217 to move laterally through the moving groove 24. The linkage rod 217 pushes the pushing block 216 in the movable groove 210 towards the center of the fixed sleeve 21. Block 216 is connected to rotating block 213 via hinge block 215, and rotating block 213 is rotatably connected to movable slot 211 of linkage plate 27 via shaft 212. At the same time, telescopic rods 214 on both sides of rotating block 213 are slidably connected to two sets of hinge blocks 215 respectively. When the push block 216 in movable slot 210 is pushed, it forces rotating block 213 to rotate around shaft 212 via hinge block 215, and then drives push block 216 in movable slot 29 to rotate synchronously via hinge block 215 on the other side. The cable moves towards the center; the arc-shaped clamping blocks 218 at the ends of the two sets of pushing blocks 216 clamp the cable, thus fixing it. The arc-shaped clamping blocks 218 at the bottom of the pushing blocks 216 within the movable slot 29 are equipped with anti-wear wheels 219. When clamped, the anti-wear wheels 219 contact the cable surface to prevent direct friction damage. When the cable is subjected to external pulling, it attempts to move within the fixed sleeve 21, but the clamping force of the arc-shaped clamping blocks 218 is transmitted through the pushing blocks 216 to the rotating block 213 and the linkage rod 217. The pawl 220 engages with the ratchet groove 24 of the ratchet disc 22, which locks the ratchet disc 22 in one direction and prevents it from reversing, thus forming a self-locking mechanism that effectively resists pulling force. If it is necessary to loosen the cable, simply lift the pawl 220 to disengage it from the teeth of the ratchet disc 22, and reverse the lever 23 to drive the push block 216 to reset the arc-shaped clamp block 218, thereby releasing the cable from its fixation. The entire control component 2, through mechanical linkage and self-locking structure, ensures that the cable is not pulled and worn during installation and maintains long-term stability after installation.
