Description

Technical Field

[0001] This application relates to the technical field of cable branch boxes, and in particular to an intelligent cable branch box. Background Technology

[0002] A cable distribution box is a specialized electrical device used for cable connection and branching in power or communication systems. Cable distribution boxes are typically installed in large factories or mines, where they are often subjected to continuous and repeated vibrations.

[0003] In related technologies, cable distribution boxes include a box body and a box door. The box door is rotatably connected to the box body. The box body has a placement slot for placing electrical components. The box body also has a through hole that connects to the placement slot, allowing cables to extend into the placement slot. The cables are fixedly connected to the terminals inside the box body by bolts.

[0004] Since cable distribution boxes are often located in large factories or mines, these locations typically experience frequent heavy transport vehicle traffic and mechanical equipment operation, resulting in long-term and continuous ground vibration. When the cable is subjected to accidental pulling or vibration transmission, the connection between the cable and the terminal block will experience relative displacement or shaking. Over time, this can easily lead to loosening of the connecting bolts, increased contact resistance, and localized heating. In severe cases, it may even generate electric sparks, causing power outages or safety accidents. Summary of the Invention

[0005] To improve the situation where cable vibration causes pulling between the cable and the terminal block, this application provides an intelligent cable branch box.

[0006] This application provides an intelligent cable branch box, which adopts the following technical solution: A smart cable branch box includes a box body with a placement groove and a through hole communicating with the placement groove. A limiting ring is slidably disposed at the through hole for the cable to pass through. The outer diameter of the limiting ring gradually increases. When the outer wall of the limiting ring abuts against the wall of the through hole, the limiting ring restricts the cable from sliding further.

[0007] By adopting the above technical solution, when the cable passes through the limiting ring, and the cable moves away from the terminal due to external force or continuous vibration, the cable moves the limiting ring in the through hole, allowing the limiting ring to abut against the hole wall. As the outer diameter of the limiting ring gradually increases, the limiting ring can press tightly against the hole wall, forming a wedge effect, which restricts the cable from continuing to slide in the through hole, thus preventing separation at the connection between the cable and the terminal and ensuring a stable connection between the cable and the terminal. This structure can respond instantly to minor cable displacement, and through the combined action of friction and wedge force between the limiting ring and the hole wall, it effectively restricts the cable from continuing to slide, preventing the tension from being transmitted to the terminal and causing bolt loosening or poor contact.

[0008] Optionally, the limiting ring is provided with a piercing block, and the placement groove is provided with a display bag; when the outer wall of the limiting ring is pressed against the hole wall of the perforation, the piercing block pierces the display bag, and the display bag is used to indicate whether it has been pierced.

[0009] By adopting the above technical solution, when the cable moves away from the terminal block, the cable drives the limiting ring to move, which in turn drives the piercing block to move. This allows the piercing block to pierce the display package, thereby alerting the user that the cable has been pulled by an external force and needs to be reset. This reduces the possibility of the cable separating from the terminal block due to continued cable movement.

[0010] Optionally, a movable groove is provided in the placement groove, a movable spring is provided in the movable groove, a movable strip is provided on the movable spring, the movable spring drives the movable strip to extend into the through hole, and the moving path of the movable strip intersects with the moving path of the limiting ring.

[0011] By adopting the above technical solution, the moving spring drives the moving strip to move, allowing the moving strip to extend out of the moving groove and into the through hole, so that the moving strip abuts against the outer surface of the cable, thereby allowing the moving strip to restrict the movement of the cable and reduce the possibility of the cable being pulled by external forces.

[0012] Optionally, the moving strip is provided with a limiting strip, which is used to restrict the moving strip from protruding through the perforation. The moving path of the limiting strip intersects with the moving path of the piercing block. When the piercing block pierces the display bag, the piercing block cuts the limiting strip.

[0013] By adopting the above technical solution, when the piercing block pierces the display package, the piercing block can pierce the limiting strip because the moving path of the limiting strip intersects with the moving path of the piercing block. This allows the limiting strip to not restrict the movement of the moving strip, so that the moving spring can smoothly drive the moving strip to move and press the moving strip against the cable. This further reduces the possibility that the cable will still move in the hole due to the subsequent continuous external force, making the connection between the cable and the terminal more stable.

[0014] Optionally, the housing is provided with a rotating hole, and a rotating sleeve is rotatably connected in the rotating hole. The through hole is opened on the rotating sleeve, and the rotating sleeve is tilted to one side, allowing the cable to pass through.

[0015] By adopting the above technical solution, the rotating sleeve can adaptively adjust its angle according to the extension direction of the cable, reducing rigid contact and friction between the cable and the edge of the hole. At the same time, the inclined setting of the rotating sleeve allows the cable to form a natural bending transition when it is inserted. When vibration is transmitted to the cable, the rotating sleeve can absorb some of the vibration energy through slight rotation, avoiding the vibration from directly acting on the connection between the cable and the terminal block. In addition, the rotating sleeve cooperates with the limiting ring. When the cable is under tension, the limiting ring moves inside the rotating sleeve and presses against the hole wall. The inclined structure of the rotating sleeve helps guide the limiting ring to quickly enter the locking state, improving the sensitivity and reliability of the anti-loosening response, thereby forming multiple protections for the cable under vibration and external force interference.

[0016] Optionally, the rotating sleeve has a receiving groove, a receiving ring is engaged in the receiving groove, the display package is disposed on the receiving ring, and the moving groove is formed on the inner wall of the receiving ring.

[0017] By adopting the above technical solution, if the display package is punctured by the puncture block, the user only needs to remove the receiving ring from the receiving groove for replacement, and then reset the cable to restore the display package's monitoring of the cable status.

[0018] Optionally, a moving block is provided on the end face of the moving strip away from the moving spring, and a moving inclined surface is provided on the moving block. The width of the moving block gradually decreases along the direction from the moving block to the moving strip. When the moving block is located in the moving groove, the receiving ring abuts against the cable. When the moving block protrudes from the moving groove, the receiving ring abuts against the cable.

[0019] By adopting the above technical solution, when the moving strip and the moving block are completely located in the moving groove, the width of the moving block gradually decreases along the direction from the moving block to the moving strip, allowing the moving block to abut against the receiving ring. Because the moving block has a moving ramp, it contacts the inner wall of the receiving ring through this ramp. Due to the gradually changing width of the moving block, the ramp gradually squeezes the receiving ring, forcing it to undergo radial elastic deformation, thus tightly gripping the outer wall of the cable. At this time, an effective sealing contact is formed between the receiving ring and the cable, significantly reducing the possibility of small animals or humid gases entering the placement groove through the gap between the cable and the receiving ring, thus improving the environmental protection level inside the enclosure. When the moving strip and the moving block protrude from the moving groove, the moving block abuts against the outer surface of the cable. Since the moving block does not drive the receiving ring to deform at this time, the receiving ring can abut against the cable.

[0020] Optionally, two receiving inclined surfaces are formed on the inner wall of the receiving ring, the moving groove is located between the two receiving inclined surfaces, and the distance between the receiving inclined surface and the other receiving inclined surface gradually decreases along the direction from the moving block to the moving strip.

[0021] By adopting the above technical solution, when the user re-attaches the receiving ring to the cable, the moving block can retract into the moving groove. The moving block drives the receiving strip to move through the moving inclined surface, so that the receiving strip abuts against the cable. Since the distance between the receiving inclined surface and the other receiving inclined surface gradually decreases along the direction from the moving block to the moving strip, the two receiving inclined surfaces can squeeze the cable and form a uniform clamping force on the cable. The large spacing area between the receiving inclined surfaces makes it easier for the moving block to retract into the moving groove, reducing the possibility of the moving block getting stuck.

[0022] In summary, this application includes at least one of the following beneficial technical effects: When the cable passes through the retaining ring, and the cable undergoes relative displacement due to external force or continuous vibration, it moves away from the terminal block. The cable causes the retaining ring to move within the through-hole, bringing it against the hole wall. As the outer diameter of the retaining ring gradually increases, it tightens against the hole wall, creating a wedge effect. This prevents the cable from sliding further within the through-hole, ensuring a stable connection between the cable and the terminal block. This structure responds instantly to minute cable displacements, effectively limiting cable slippage through the combined friction and wedge force between the retaining ring and the hole wall, preventing tension from being transmitted to the terminal block and causing bolt loosening or poor contact.

[0023] When the moving strip and moving block are fully within the moving groove, the width of the moving block gradually decreases along the direction from the moving block to the moving strip, allowing the moving block to abut against the receiving ring. Because the moving block has a moving ramp, it contacts the inner wall of the receiving ring through this ramp. Due to the gradually changing width of the moving block, the ramp gradually compresses the receiving ring, forcing it to undergo radial elastic deformation, thus tightly gripping the outer wall of the cable. At this point, an effective sealing contact is formed between the receiving ring and the cable, significantly reducing the possibility of small animals or humid gases entering the placement groove through the gap between the cable and the receiving ring, thus improving the environmental protection level inside the enclosure. When the moving strip and moving block protrude from the moving groove, the moving block abuts against the outer surface of the cable. Since the moving block does not drive the receiving ring to deform at this time, the receiving ring can abut against the cable. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0027] This embodiment discloses an intelligent cable branch box. (Refer to...) Figure 1 and Figure 2 An intelligent cable distribution box includes a box body 1, on which a placement slot 11 for storing electrical components is provided. The electrical components inside the box body 1 can realize the basic function of cable distribution. The box body 1 has wiring terminals for cable installation by bolts.

[0028] Reference Figure 3The bottom of the housing 1 has multiple rotating holes 12, and rotating sleeves 2 are rotatably connected to each of the rotating holes 12. The rotating sleeves 2 are threaded onto the rotating holes 12. One end of the rotating sleeve 2 is tilted to one side. A through hole 21 is provided inside the rotating sleeve 2 for the cable to pass through. When the cable passes through the through hole 21, the rotating sleeve 2 can rotate according to the different angles of the cable insertion, so that the rotating sleeve 2 can protect the cable and reduce the damage to the cable.

[0029] Reference Figure 3 and Figure 4 A receiving groove 22 is provided on the end face of the rotating sleeve 2, extending circumferentially along the rotating sleeve 2, i.e., the receiving groove 22 is annular. A receiving ring 3 is provided inside the receiving groove 22, and an elastic ring 221 is fixedly connected to the groove wall of the receiving groove 22. The elastic ring 221 is located on the side of the receiving ring 3 away from the bottom wall of the receiving groove 22, i.e., the elastic ring 221 prevents the receiving ring 3 from detaching from the receiving groove 22, allowing the receiving ring 3 to be engaged with the rotating sleeve 2. A through hole 31 is provided on the outer surface of the receiving ring 3, allowing the cable to pass through, i.e., the operator can directly reinstall the receiving ring 3 onto the rotating sleeve 2 through the through hole 31.

[0030] Reference Figure 3 Two display slots 32 are formed on the end face of the receiving ring 3, and a display package 321 is placed in the display slots 32. The display package 321 is filled with paint. A limiting ring 4 is sleeved on the cable. The inner wall of the limiting ring 4 is provided with barbs, and the outer diameter of the limiting ring 4 gradually decreases in the vertical downward direction. A piercing block 41 is fixedly connected to the end face of the limiting ring 4 away from the ground. The piercing block 41 is used to pierce the display package 321.

[0031] Reference Figure 3 When the cable is pulled outward by external force, the cable drives the limiting ring 4 to move towards the through hole 21, so that the outer wall of the limiting ring 4 can press against the hole wall of the through hole 21, thereby limiting the cable to continue moving. At this time, the piercing block 41 in the limiting ring 4 can pierce the display package 321, allowing the paint in the display package 321 to spread onto the receiving ring 3, so as to remind the staff that the cable needs to be reset.

[0032] Reference Figure 3 Two movable grooves 33 are formed on the inner wall of the receiving ring 3. The two movable grooves 33 are symmetrically arranged and connect to the display groove 32. A movable spring 331 is fixedly connected to the bottom wall of the movable groove 33. A movable strip 332 is fixedly connected to the end of the movable spring 331 away from the bottom wall of the movable groove 33. The movable spring 331 drives the movable strip 332 to protrude from the movable groove 33 and insert into the through hole 21. The movement path of the movable strip 332 intersects with the movement path of the limiting ring 4. When the movable strip 332 is inserted into the through hole 21, the movable strip 332 can abut against the limiting ring 4 to limit the limiting ring 4 from moving further downward.

[0033] Reference Figure 3 A limiting strip 333 is fixedly connected to the end face of the moving strip 332 near the moving spring 331. The limiting strip 333 has elastic deformation capability and is easily punctured by the puncturing block 41. When the puncturing block 41 punctures the display package 321, as the limiting ring 4 continues to fall, the puncturing block 41 can puncture and cut the limiting strip 333, releasing the limiting strip 333 from restricting the moving strip 332.

[0034] Reference Figure 3 A moving block 334 is fixedly connected to the end face of the moving bar 332 away from the moving spring 331. Moving inclined surfaces 335 are provided on both surfaces of the moving block 334 in the vertical direction. The distance between the two moving inclined surfaces 335 gradually decreases along the direction from the moving block 334 to the moving bar 332.

[0035] Reference Figure 3 and Figure 5 The inner wall of the receiving ring 3 has two receiving inclined surfaces 34, and the moving groove 33 is located between the two receiving inclined surfaces 34. The distance between the receiving inclined surface 34 and the other receiving inclined surface 34 gradually decreases along the direction from the moving block 334 to the moving strip 332. The inner wall of the receiving ring 3 has two clearance inclined surfaces 341. The receiving inclined surface 34 is located on the side of the clearance inclined surface 341 away from the moving groove 33. The distance between the clearance inclined surface 341 and the other clearance inclined surface 341 gradually decreases along the direction from the moving block 334 to the moving strip 332, and the inclination angle of the clearance inclined surface 341 is the same as the inclination angle of the moving inclined surface 335.

[0036] Reference Figure 3 When the receiving ring 3 abuts against the cable and the limiting strip 333 still restricts the movement of the moving strip 332, the moving block 334 and the moving strip 332 are both located in the moving groove 33, and the moving inclined surface 335 abuts against the yielding inclined surface 341. At this time, since the thickness of the moving block 334 is greater than the thickness of the moving strip 332, the moving block 334 drives the receiving ring 3 to deform, so that both receiving inclined surfaces 34 can abut against the cable, and the receiving inclined surface 34 and the cable are in line contact; at the same time, the limiting strip 333 bends and tilts upward so that the piercing block 41 can pierce the limiting strip 333 and break it quickly.

[0037] Reference Figure 3 When the receiving ring 3 abuts against the cable and the limiting strip 333 is cut or punctured, the moving spring 331 drives the moving strip 332 to move, so that the moving block 334 abuts against the cable. At this time, the moving inclined surface 335 does not abut against the yielding inclined surface 341, that is, the moving block 334 does not drive the receiving ring 3 to continue to deform, so that the two receiving inclined surfaces 34 can abut against the cable. The receiving inclined surface 34 and the cable are in surface contact, which further strengthens the limiting of the cable.

[0038] The implementation principle of an intelligent cable branch box according to an embodiment of this application is as follows: when the receiving ring 3 abuts against the cable and the limiting strip 333 still restricts the movement of the moving strip 332, the moving block 334 and the moving strip 332 are both located in the moving groove 33, and the moving inclined surface 335 abuts against the yielding inclined surface 341. At this time, since the thickness of the moving block 334 is greater than the thickness of the moving strip 332, the moving block 334 drives the receiving ring 3 to deform, so that both receiving inclined surfaces 34 can abut against the cable, and the receiving inclined surface 34 and the cable are in line contact.
