Description

Technical Field

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

[0002] A cable distribution box is a device used in power systems to connect, branch, and switch cable lines. It is commonly used in outdoor power distribution networks and is mainly used in substations, distribution stations, industrial parks, municipal buildings, and other places.

[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 receiving slot for placing electrical components. The box body has multiple through holes that connect to the receiving slots for wires to pass through. Rubber sleeves are provided at the through holes, and the wires pass through the rubber sleeves and extend into the receiving slots.

[0004] The wire passes through the rubber sleeve and extends into the receiving groove. If the wire moves due to external pulling, the connection between the wire and the electrical components inside the box will be relatively displaced, affecting the stability of the connection between the wire and the electrical components. Summary of the Invention

[0005] To address the issue of workers relying on experience to secure wires with clamps, this application provides a cable branch box.

[0006] This application provides a cable branch box, which adopts the following technical solution: A cable branch box includes a box body with a receiving groove and a through hole communicating with the receiving groove for a wire to pass through. The box body has a fixing ring for the wire to pass through, and a stop ring rotatably connected to the fixing ring. The fixing ring has multiple first moving grooves extending from the outer wall to the inner wall of the fixing ring. The stop ring has multiple second moving holes extending circumferentially along the stop ring. A moving strip is slidably connected within each of the first moving grooves, passing through the second moving holes. A moving block is provided on the moving strip, and the moving block can abut against the outer surface of the wire.

[0007] By adopting the above technical solution, the worker first inserts the wire through the hole into the fixing ring and the stop ring. Then, the worker rotates the stop ring, causing the moving strip to slide through the wall of the second moving hole. Since the second moving hole extends circumferentially along the stop ring, and the moving strip slides in the first moving groove, and the first moving groove extends from the outer wall to the inner wall of the fixing ring, the moving strip can move from the outer side to the inner side of the fixing ring, allowing the moving block to abut against the outer surface of the wire. This clamps and fixes the wire, reducing the possibility of the wire sliding at the hole and thus enhancing the connection stability between the wire and the connector.

[0008] Optionally, the stop ring is provided with a plurality of stop strips, which are distributed along the circumference of the stop ring and are all bent along the circumference of the stop ring. The fixed ring is provided with an annular groove for the stop ring to rotate, and a stop block is rotatably connected in the annular groove. The stop block is located on the rotation path of the stop strip and is used to restrict the stop ring from reversing.

[0009] By adopting the above technical solution, when the operator rotates the stop ring, the stop block is located on the rotation path of the stop strip, and the stop strip drives the stop block to rotate. In addition, the stop strips are distributed along the circumference of the stop ring, and multiple stop strips are bent along the circumference of the stop ring, so that the stop block can restrict the stop strip from reversing. This achieves the goal of the stop block restricting the reversal of the stop ring, thereby reducing the situation where the moving block fails to contact the wire due to the reversal of the stop ring, and further increasing the reliability between the moving block and the wire.

[0010] Optionally, a limiting hole is formed on the surface of the movable block near the wire, a limiting strip is slidably connected in the limiting hole, and a limiting sleeve for sealing the limiting hole is provided on the movable block, the limiting strip being able to pierce the limiting sleeve; when the movable block presses against the wire, the limiting strip pierces the limiting sleeve and protrudes from the limiting hole.

[0011] By adopting the above technical solution, when the moving block is pressed against the wire, one end of the limiting strip abuts against the wire, and the other end of the limiting strip abuts against the limiting sleeve. At this time, the limiting strip can pierce the limiting sleeve, allowing one end of the limiting strip to protrude from the limiting hole. At this time, the operator can know that the moving block has clamped the wire, preventing the operator from continuing to rotate the stop ring. By having the limiting strip pierce the limiting sleeve and protrude from the limiting hole, the operator does not need to rely on experience to judge whether the moving block has clamped the wire, which greatly reduces the difficulty of operation for the operator and improves the accuracy of operation.

[0012] Optionally, the moving strip is provided with a receiving groove, and a receiving block is slidably connected in the receiving groove. The first moving groove is provided with a locking groove for the receiving block to be inserted. When the receiving block is inserted into the locking groove, the moving strip is fixed in the first moving groove.

[0013] By adopting the above technical solution, the sliding receiving block is moved from the receiving groove to the locking groove, thereby limiting the receiving block by the groove wall of the locking groove. This prevents the moving strip from continuing to slide in the first moving groove, further increasing the reliability of the fixation between the moving strip and the fixed ring and reducing the possibility of the moving strip accidentally sliding. The receiving block is inserted into the locking groove to achieve a first locking, and the stop block abuts against the stop strip to achieve a second locking. The double locking reduces the possibility of the stop ring rotating.

[0014] Optionally, the movable strip has a connecting hole that connects the receiving groove and the limiting hole. A connecting strip is slidably connected in the connecting hole. The end face of the connecting strip near the receiving groove is an arc surface. The limiting strip has a moving part. The limiting strip drives the connecting strip to be inserted into the receiving groove through the moving part. The moving path of the connecting strip intersects with the sliding path of the receiving block. When the limiting strip pierces the limiting sleeve and protrudes from the limiting hole, the connecting strip drives the receiving block to be inserted into the locking groove.

[0015] By adopting the above technical solution, when the limiting strip pierces the limiting sleeve and protrudes from the limiting hole, the limiting strip drives the connecting strip to move through the moving part, allowing the connecting strip to be inserted into the receiving groove. Since the end face of the connecting strip near the receiving groove is an arc surface, the connecting strip can drive the receiving block to move within the receiving groove, thereby allowing the receiving block to be inserted into the locking groove, thus locking the receiving block to the moving strip. By piercing the limiting sleeve with the limiting strip, the limiting strip drives the receiving block to move through the connecting strip, eliminating the need for manual movement of the receiving block by the operator and reducing the number of steps required.

[0016] Optionally, the movable component includes a first magnet and a second magnet. The first magnet is disposed on the limiting strip, and the second magnet is disposed on the connecting strip. The first magnet repels the second magnet. When the limiting strip pierces the limiting sleeve and protrudes from the limiting hole, the connecting strip can drive the receiving block to move.

[0017] By adopting the above technical solution, when the limiting strip pierces the limiting sleeve and protrudes from the limiting hole, the first magnet of the limiting strip can repel the second magnet, so that the second magnet drives the connecting strip to move in the connecting hole, thereby allowing the connecting strip to be inserted into the receiving groove.

[0018] Optionally, a third magnet is provided in the limiting hole, and the third magnet attracts the second magnet; when the limiting strip is disengaged from the limiting hole, the third magnet attracts the second magnet, and at this time the connecting strip does not abut against the receiving block.

[0019] By adopting the above technical solution, when the staff needs to remove the wire, the staff first removes the limiting strip from the limiting hole. At this time, the third magnet can attract the second magnet, that is, the connecting strip can slide in the connecting hole, allowing the connecting strip to disengage from the receiving groove. Then the staff forcibly rotates the stop ring, and the receiving block can return to the receiving groove to release the limiting of the moving strip by the receiving block.

[0020] Optionally, the limiting strip is provided with a limiting spring, and the wall of the limiting hole is provided with a limiting groove for the limiting spring to be inserted; when the limiting spring is inserted into the limiting groove, the limiting strip pierces the limiting sleeve and protrudes from the limiting hole.

[0021] By adopting the above technical solution, when the limiting spring is inserted into the limiting groove, the groove wall of the limiting groove limits the limiting spring, so that the limiting spring can prevent the limiting strip from detaching from the limiting hole, thereby further increasing the stability of the limiting strip in the moving block.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The worker first inserts the wire through the hole into the fixing ring and the stop ring. Then, the worker rotates the stop ring, causing it to slide along the wall of the second moving hole. Since the second moving hole extends circumferentially along the stop ring, and the moving strip slides in the first moving groove, which extends from the outer wall to the inner wall of the fixing ring, the moving strip can move from the outer side to the inner side of the fixing ring. This allows the moving block to abut against the outer surface of the wire, clamping and fixing the wire, reducing the possibility of the wire sliding at the hole, and thus enhancing the connection stability between the wire and the connector.

[0023] 2. When the moving block is pressed against the wire, one end of the limiting strip abuts the wire, and the other end of the limiting strip abuts the limiting sleeve. At this time, the limiting strip can pierce the limiting sleeve, allowing one end of the limiting strip to protrude from the limiting hole. At this point, the operator can know that the moving block has clamped the wire, preventing the operator from continuing to rotate the stop ring. By having the limiting strip pierce the limiting sleeve and protrude from the limiting hole, the operator does not need to rely on experience to judge whether the moving block has clamped the wire, greatly reducing the difficulty of operation and improving the accuracy of operation.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0027] This embodiment discloses a cable branch box. (Refer to...) Figure 1 A cable branch box includes a box body 1 and a box door 11. The box door 11 is rotatably connected to the box body 1. The box body 1 has a receiving slot 12 for placing electrical components.

[0028] Reference Figure 2 The housing 1 has multiple through holes 13 that connect to the receiving groove 12, and each through hole 13 allows a wire to pass through. Multiple fixing rings 2 are fixedly connected within the receiving groove 12, and each fixing ring 2 corresponds to a different through hole 13. A groove 21 is formed on the surface of the fixing ring 2 away from the ground, extending circumferentially along the fixing ring 2.

[0029] Reference Figure 2 A stop ring 3 is rotatably connected within the annular groove 21, through which a wire passes. Multiple stop strips 31 are fixedly connected to the outer surface of the stop ring 3, bending circumferentially and arranged in an array along the circumferential direction. A stop groove 211 is formed on the wall of the annular groove 21, extending circumferentially. A stop block 212 is rotatably connected within the stop groove 211, extending circumferentially along the annular groove 21. The rotation path of the stop block 212 intersects with the rotation path of the stop strips 31. A torsion spring is provided on the stop block 212, which can reset the stop block 212, ensuring it remains within the annular groove 21.

[0030] Reference Figure 2 When the stop strip 31 rotates, it drives the stop block 212 to rotate within the stop groove 211, allowing the stop strip 31 to pass over the stop block 212. The stop block 212, lacking the contact of the stop strip 31, returns to its original position, allowing it to contact the next stop strip 31. When the stop ring 3 rotates, the stop strip 31 drives the stop block 212 to rotate, and the stop ring 3 cannot reverse direction.

[0031] Reference Figure 2 The fixed ring 2 has multiple first moving grooves 22 on its surface away from the ground. The multiple first moving grooves 22 are arranged in a circumferential array along the fixed ring 2 and extend from the outer wall to the inner wall of the fixed ring 2. The stop ring 3 has multiple second moving holes 32 on its surface away from the ground. The multiple second moving holes 32 are arranged in a circumferential array along the stop ring 3 and are inclined along the circumferential direction of the stop ring 3.

[0032] Reference Figure 2 and Figure 3 A movable strip 4 is slidably connected within the first movable groove 22, and the movable strip 4 can pass through the second movable hole 32. A movable block 41 is integrally formed on the surface of the movable strip 4, and the movable block 41 and the movable strip 4 are arranged perpendicularly to each other. When the stop ring 3 rotates, the stop ring 3 drives the movable strip 4 to slide within the first movable groove 22 through the second movable hole 32, allowing the movable block 41 to abut against the wire, thereby fixing the wire with the movable block 41.

[0033] Reference Figure 4 A limiting hole 42 is formed on the surface of the movable block 41 near the conductor. A limiting strip 421 is slidably connected inside the limiting hole 42. The length of the limiting strip 421 is greater than the length of the limiting hole 42, that is, the limiting strip 421 can protrude from the movable block 41. A limiting sleeve 422 is adhered to the surface of the movable block 41 away from the conductor. The limiting sleeve 422 can be pierced by the limiting strip 421.

[0034] Reference Figure 4 When the moving block 41 presses against the wire, the wire pushes the limiting strip 421 to pierce the limiting sleeve 422, allowing the end of the limiting strip 421 away from the wire to protrude from the limiting hole 42. At this time, the staff can know that the moving block 41 has pressed against the wire.

[0035] Reference Figure 4 and Figure 5A limiting groove 43 is formed on the wall of the limiting hole 42. Limiting spring pieces 431 are fixedly connected to the surfaces of opposite sides of the limiting strip 421. The limiting spring pieces 431 bend and deform in the direction away from the wire, and can be inserted into the limiting groove 43. When the end of the limiting strip 421 away from the wire protrudes from the limiting hole 42, the limiting spring piece 431 can be inserted into the limiting groove 43, thereby limiting the limiting strip 421 and preventing the limiting strip 421 from detaching from the limiting hole 42.

[0036] Reference Figure 4 and Figure 6 Each of the two opposite surfaces of the movable strip 4 has a receiving groove 44, and a connecting hole 441 is provided on the movable strip 4, connecting the two receiving grooves 44 and the limiting hole 42. A receiving block 442 is slidably connected in the receiving groove 44, and a connecting strip 443 is slidably connected in the connecting hole 441. The surface of the connecting strip 443 facing the receiving groove 44 is an arc surface, and the connecting strip 443 can be inserted into the receiving groove 44, that is, the sliding path of the connecting strip 443 intersects the sliding path of the receiving block 442.

[0037] Reference Figure 2 and Figure 6 Multiple locking grooves 221 are provided on the groove walls on both sides of the first moving groove 22. The multiple locking grooves 221 are arranged in an array along the length direction of the first moving groove 22, and the locking grooves 221 are for the insertion of the receiving block 442. When one end of the receiving block 442 protrudes from the receiving groove 44 and is inserted into the locking groove 221, the receiving block 442 can limit the moving bar 4, so that the moving bar 4 and the fixing ring 2 are fixed to each other.

[0038] Reference Figure 2 , Figure 4 and Figure 6 The limiting strip 421 is provided with a movable component 45, which includes a first magnet 451 and a second magnet 452, which repel each other. The first magnet 451 is fixedly connected to the limiting strip 421, and the second magnet 452 is fixedly connected to the surface of the connecting strip 443 away from the ground. When one end of the limiting strip 421 pierces the limiting sleeve 422 and protrudes from the limiting hole 42, the first magnet 451 aligns with the connecting hole 441, that is, the first magnet 451 repels the second magnet 452, allowing the connecting strip 443 to be smoothly inserted into the receiving groove 44. This enables the connecting strip 443 to drive the receiving block 442 to protrude from the receiving groove 44 and insert into the locking groove 221, thereby fixing the movable strip 443 in the first movable groove 22.

[0039] Reference Figure 4 and Figure 6A third magnet 453 is fixedly connected to the wall of the limiting hole 42. The third magnet 453 is aligned with the connecting hole 441 and attracts the second magnet 452. When the end of the limiting strip 421 away from the wire does not protrude from the moving block 41, the third magnet 453 can attract the second magnet 452. At this time, since the first magnet 451 is not close to the second magnet 452, the force exerted by the first magnet 451 on the second magnet 452 is less than the force exerted by the third magnet 453 on the second magnet 452, allowing the connecting strip 443 to move from the receiving groove 44 into the connecting hole 441.

[0040] Reference Figure 2 , Figure 4 and Figure 6 When the staff first removes the limiting strip 421 from the limiting hole 42, the first magnet 451 will not repel the second magnet 452, so that the third magnet 453 can attract the second magnet 452, allowing the connecting strip 443 to move from the receiving groove 44 to the connecting hole 441. The staff can then forcibly rotate the stop ring 3 to unlock the moving block 41 from the wire.

[0041] The implementation principle of a cable branch box in this application embodiment is as follows: the worker first passes the wire through the through hole 13, the fixing ring 2 and the stop ring 3, and then the worker rotates the stop ring 3 until the limit strip 421 pierces the limit sleeve 422 and protrudes from the limit hole 42. At this time, the worker can know that the moving block 41 is pressed against the wire.
