Description

Technical Field

[0001] This utility model relates to the field of auxiliary technology for subway power distribution, and more specifically, it relates to a cable splitter for subway power distribution. Background Technology

[0002] During subway construction, many cables are used to connect various devices. In subway power distribution, the cables used are generally made up of multiple wires twisted together. When in use, the cables need to be split into individual wires and connected to the corresponding devices through a splitting device.

[0003] Common cable splitting devices often incorporate a fixing structure to prevent cables from detaching from the equipment. After the individual cables are placed into the splitting structure, the fixing structure covers one side of the cable to prevent it from leaving the device. However, these fixing structures are typically secured with bolts. Disassembling these bolted structures requires workers to use tools to tighten each bolt individually, which is inconvenient and inefficient. Furthermore, to allow cables to pass freely, the splitting structure is designed with sufficient space for individual wires. After splitting, the wires are not fixed and will move around within the structure's space, making them unstable and affecting usability. Additionally, when splitting cables into multiple individual wires, the space constraints of the splitting device mean some wires need to bend to the sides, inevitably coming into contact with the sharp edges of the splitting structure. Common splitting structures have sharp edges that can easily cause wear and tear on the wires, affecting their lifespan. Utility Model Content

[0021] Please see Figure 1-5A cable splitter for subway power distribution includes a housing 1. One end of the housing 1 has a cable port 2, and the other end has a splitting port 3. Multiple splitting ports 3 are provided and are arranged at equal intervals. One end of the housing 1 is rotatably connected to a fixing cover 4. The other end of the fixing cover 4 is provided with an insertion block 5. An insertion groove 6 is provided on the housing 1. The insertion block 5 cooperates with the insertion groove 6. A limiting post 7 is slidably connected to one end of the insertion groove 6. A limiting hole 8 is provided on the insertion block 5. The European-style limiting post 7 cooperates with the limiting hole 8. One end of the branch port 3 is provided with a telescopic groove 9, and a drive screw 10 is rotatably connected in the telescopic groove 9. A control wheel 11 is rotatably connected on the housing 1. One end of the drive screw 10 is fixedly connected to the control wheel 11. A telescopic column 12 is slidably connected in the telescopic groove 9. One end of the telescopic column 12 cooperates with the drive screw 10, and the other end is provided with a pressure block 13.

[0022] In this embodiment, the housing 1 provides the structure for wire splitting. By pulling the limiting post 7, the limiting post 7 is separated from the limiting hole 8, releasing the restriction on the insertion block 5. The fixing cover 4 is rotated to open, exposing the interior of the housing 1. The cable is inserted into the housing 1 through the cable port 2, and the wires in the cable are separated and passed out from different split ports 3 as needed. After confirming the position of each wire, the fixing cover 4 is rotated to allow the insertion block 5 to enter the insertion slot 6, so that the fixing cover 4 covers the housing 1. The limiting post 7 is controlled to slide and insert into the limiting hole 8 to restrict the insertion block 5, thereby restricting the fixing cover 4 and covering the top of the housing 1 to prevent the wires from falling out of the split port 3.

[0023] More specifically, during wire splitting, the wire is placed into the splitting port 3, and then the control wheel 11 is rotated, causing the control wheel 11 to rotate with the drive screw 10. The drive screw 10 cooperates with the telescopic column 12, which is restricted by the telescopic groove 9 and moves under the drive of the drive screw 10. This causes the telescopic column 12 to move with the pressure block 13 toward the wire. Through the cooperation of the pressure block 13 with the other side of the splitting port 3, it contacts the wire and clamps and fixes the wire, keeping the wire stable in the splitting port 3.

[0024] Please see Figure 2 , Figure 3 and Figure 5 As one embodiment of the pressure block 13: both the pressure block 13 and the dividing port 3 are provided with notches and grooves 14 on the side away from the pressure block 13. A support shaft 15 is provided in the notch and groove, and a contact roller 16 is rotatably connected to the support shaft 15.

[0025] Specifically, the notch 14 provides installation space, and the support shaft 15 enables the contact roller 16 to cooperate with the wire. The arc surface of the contact roller 16 adapts to the bending of the wire, making the wire fit more tightly. When the wire is pulled, the contact roller 16 will rotate under the fixation of the support shaft 15 to adapt to the movement of the wire, reduce wear on the wire, and improve the life of the wire.

[0026] Please see Figures 2-4 As a further embodiment of the housing: a sliding groove 17 is provided at one end of the housing 1, and a pressure ring 18 is provided on the limiting post 7. The pressure ring 18 is slidably engaged with the sliding groove 17, and a pressure spring 19 is provided between the pressure ring 18 and the inner wall of the sliding groove 17. The limiting post 7 passes through the middle of the pressure spring 19.

[0027] Specifically, the structure provided by the sliding groove 17 pushes the pressure ring 18 under the thrust of the pressure spring 19, so that the fit between the limiting post 7 and the limiting hole 8 remains stable.

[0028] Please see Figures 2-4 As a further embodiment of the limiting post: multiple sets of limiting posts 7 are provided, and a pull plate 20 is provided on one side of the housing 1. The limiting posts 7 are all fixedly connected to the pull plate 20.

[0029] Specifically, a control structure is provided by pulling plate 20, and by controlling pulling plate 20, multiple limiting columns 7 are moved simultaneously.

[0030] Please see Figure 2 As a further embodiment of the cable port: a support ring 21 is fixedly connected to one end of the cable port 2, and a clamping ring 22 is slidably connected to the other end. A support block 23 is provided on one side of the clamping ring 22 in the housing 1. An adjusting bolt 24 is provided on the support block 23. The adjusting bolt 24 is threadedly engaged with the support block 23 and rotatably connected to the clamping ring 22.

[0031] Specifically, the support block 23 provides a support structure, controls the rotation of the adjusting bolt 24, and moves the adjusting bolt 24 along the support block 23. When the adjusting bolt 24 moves, it moves the clamping ring 22. Through the cooperation of the clamping ring 22 and the support ring 21, the inserted cable is clamped and fixed.

[0032] Please see Figure 2 As a further embodiment of the insert block: the lower end of the insert block 5 is provided with an arc-shaped head 25.

[0033] Specifically, the curved head 25 provides an arc surface, which, when the cable extends from the branch port 3, cooperates with the limiting head to change the direction of force, causing the insertion block 5 of the limiting head to be pushed aside.

[0034] Please see Figure 1 and Figure 2As a further embodiment of the fixed cover: the fixed cover 4 is provided with a pull handle 26.

[0035] Specifically, the control structure provided by pulling handle 26 facilitates the movement of the fixed cover 4.

[0036] Please see Figure 5 As a further embodiment of the pressure block: the pressure block 13 is provided with a protective pad 27.

[0037] Specifically, the pressure block 13 contacts the wire through the protective pad 27, reducing damage to the wire.

[0038] In summary, when the overall equipment is in use (or running): When the structure provided by housing 1 is used for wire splitting, the pull plate 20 is controlled to simultaneously move multiple limiting posts 7, causing the limiting posts 7 to separate from the limiting holes 8, releasing the restriction on the insertion block 5. The control structure provided by pull handle 26 is then used to open the fixing cover 4, exposing the interior of housing 1. The cable is then inserted into housing 1 through cable port 2, and the wires in the cable are separated and exited from different split ports 3 as needed. After confirming the position of each wire, the fixing cover 4 is rotated to allow the insertion block 5 to enter the insertion slot 6. The arc-shaped head 25 provides the arc surface for wire splitting. When the cable extends into the branch port 3, it cooperates with the limiting head to change the direction of force, making room for the insertion of the limiting head into the insertion block 5, facilitating the insertion of the insertion block 5, allowing the fixing cover 4 to cover the housing 1, and controlling the sliding of the limiting post 7 so that the limiting post 7 is inserted into the limiting hole 8. The sliding groove 17 provides the structure, and under the thrust of the pressure spring 19, it pushes the pressure ring 18 to keep the cooperation between the limiting post 7 and the limiting hole 8 stable, thus limiting the insertion block 5, thereby limiting the fixing cover 4, so that the fixing cover 4 covers the top of the housing 1, preventing the cable from coming off the branch port 3.

[0039] During cable splitting, the support block 23 provides a support structure, and the adjusting bolt 24 is rotated to move along the support block 23. As the adjusting bolt 24 moves, it moves the clamping ring 22 along with it. Through the cooperation of the clamping ring 22 and the support ring 21, the inserted cable is clamped and fixed. The cable is then placed into the splitting port 3. Next, the control wheel 11 is rotated, causing the drive screw 10 to rotate. The drive screw 10 cooperates with the telescopic column 12, which is restricted by the telescopic groove 9 and moves under the drive of the drive screw 10. This causes the telescopic column 12 to move along with the pressure block 13 towards the cable. The pressure block 13 contacts the wire through the protective pad 27, reducing damage to the wire. Through the cooperation of the pressure block 13 with the inner side of the wire splitting port 3, it contacts the wire and clamps and fixes the wire, keeping the wire stable in the wire splitting port 3. The notch 14 provides installation space. With the support of the support shaft 15, the contact roller 16 cooperates with the wire. The arc surface of the contact roller 16 adapts to the bending of the wire, making the wire fit more tightly. When the wire is pulled, the contact roller 16 will rotate under the fixation of the support shaft 15, adapting to the movement of the wire, reducing wear on the wire, and improving the wire life.

For all the fixed connections mentioned above, welding is preferred.
