Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harnessing, and in particular to a wire harnessing mechanism for electrical cabinets. Background Technology
[0002] Electrical cabinets, also known as distribution cabinets, are key components in power systems and various industrial equipment. Their main function is to distribute electrical energy and ensure that power can be smoothly delivered to various load points. Electrical cabinets are widely used in many fields such as chemical industry, environmental protection industry, power system, metallurgical system, nuclear power industry, fire safety monitoring, and transportation industry.
[0003] Electrical cabinets contain various components such as busbars, circuit breakers, relays, integrated relay protection devices, and metering instruments. These components work together to achieve effective monitoring and control of the power system. However, due to the large number of components, there are also many wires inside the electrical cabinet. To improve the safety of the wires inside the electrical cabinet and facilitate subsequent maintenance, wire harnesses are generally used to arrange these wires neatly. A wire harness is usually a simple clip. By fixing it to the inner wall of the electrical cabinet, the wires are clipped onto the wire harness, thus limiting the movement of the wires and transforming multiple messy wires into an orderly circuit. This facilitates subsequent maintenance and improves the safety of the circuit.
[0004] Existing wire harnessing devices have a relatively simple structure. Once the wire is secured inside the device, it is essentially immobile. This can lead to the wire being too loose if the locking position is not accurate. Consequently, the portion of the wire between the harnessing device and the component may not be straightened, causing it to bend and affecting the arrangement of multiple wires. In this case, the wire must be removed from the harnessing device and the harnessing process repeated. This not only makes the operation cumbersome but also causes friction between the wire and the harnessing device during the repeated harnessing process, resulting in wear and tear on the wire's outer sheath.
[0005] Therefore, it is necessary to provide a new wiring harness mechanism for electrical cabinets to solve the above-mentioned technical problems. Utility Model Content
[0006] To solve the above-mentioned technical problems, this utility model provides a wire harness mechanism for electrical cabinets.
[0007] The electrical cabinet wiring harness mechanism provided by this utility model includes a limiting frame A, a limiting frame B rotatably connected to the top side of the limiting frame A, limiting openings in both the limiting frame A and the limiting frame B, and a slot communicating with the limiting opening on one side of both the limiting frame A and the limiting frame B, and an installation groove on the inner wall of both the limiting frame A and the limiting frame B away from the slot, and a communicating cavity communicating with the installation groove on one side of both the limiting frame A and the limiting frame B, two transmission rollers rotatably connected in the installation groove, a transmission belt sleeved between the two transmission rollers in the same installation groove, a sleeve rotatably connected in the communicating cavity, one end of the sleeve fixedly connected to the transmission roller on the same side, an installation rod slidably connected to the end of the sleeve away from the transmission roller, an installation plate fixedly connected to the installation rod, and several ring-shaped and uniformly distributed locking blocks fixedly connected to the side of the installation plate near the sleeve.
[0008] A limiting ring is fixedly connected inside the communicating cavity. The limiting ring is located between the transmission roller and the mounting plate. Several slots are evenly distributed in a ring on the side of the limiting ring near the mounting plate. The locking blocks are all located in the corresponding slots.
[0009] Preferably, the inner walls on both sides of the bayonet of the limiting frame A and the limiting frame B are provided with limiting grooves, and a baffle is slidably connected in the limiting groove. A number of fixing springs are fixedly connected between the baffle and the inner wall of the limiting groove on the same side.
[0010] Preferably, an arc-shaped storage groove is provided on one side of the limiting frame A, and a hook is fixedly connected to the side of the limiting frame A away from the bayonet.
[0011] Preferably, a semi-circular scale is fixedly connected to one side of the bottom of the limiting frame B, and the end of the scale away from the limiting frame B is located in the storage groove.
[0012] Preferably, a limit spring is fixedly connected between one end of the mounting rod and the inner wall of the sleeve, and a knob is fixedly connected to the end of the mounting rod away from the sleeve.
[0013] Preferably, the limiting frame A is provided with a fixing plate on the side near the hook, and several rows of evenly distributed hanging rings are fixedly connected to the fixing plate, and the limiting frame A is hung on the hanging rings by the hook.
[0014] Preferably, the transmission roller has a structure that is thicker at both ends and thinner in the middle, and the transmission belt is provided with a number of evenly distributed anti-slip blocks.
[0015] Compared with related technologies, the wiring harness mechanism for electrical cabinets provided by this utility model has the following advantages:
[0016] In this invention, after the wire is secured in the limiting slot, if the wire is not straightened, the mounting rod can be pulled outwards from the sleeve by turning the knob. At this point, the locking block on the mounting plate will be pulled out of the slot on the limiting ring. The mounting rod then drives the transmission roller to rotate, which in turn drives the transmission belt. This transmission belt moves the wire within the limiting slot, allowing for fine-tuning. Once the wire is straightened, the knob is released, causing the limiting spring to rebound, moving the mounting rod inwards and the mounting plate, re-locking the locking block in the slot. This completes the limiting function of the transmission roller. The limiting transmission belt then restricts the wire within the limiting slot, preventing it from moving due to external force. This avoids the problem of repeated wire bundling work required in traditional devices, which causes friction between the wire and the bundling device, resulting in wear on the wire's outer sheath.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0028] Please see Figures 1 to 8 This utility model provides a wiring harness mechanism for an electrical cabinet, including a limiting frame A1. A limiting frame B2 is rotatably connected to the top side of the limiting frame A1. Both the limiting frame A1 and the limiting frame B2 have limiting openings 11. Both the limiting frame A1 and the limiting frame B2 have a slot 12 communicating with the limiting opening 11 on one side. Both the limiting frame A1 and the limiting frame B2 have a mounting groove 14 on the side of their inner walls away from the slot 12. Both the limiting frame A1 and the limiting frame B2 have a communicating cavity 15 communicating with the mounting groove 14 on one side. One side of the limiting frame A1 has an arc-shaped storage groove 16. A semi-circular scale 21 is fixedly connected to the bottom side of the limiting frame B2, with the end of the scale 21 away from the limiting frame B2 located in the storage groove 16.
[0029] It should be noted that: Limiting bracket A1 and limiting bracket B2 have the same structure, but the length of limiting bracket B2 is less than that of limiting bracket A1. After installing limiting bracket A1 inside the appliance cabinet, if it is necessary to bend the wire, first pass the wire through the locking slot 12 of limiting bracket A1 into the limiting slot 11, and then manually rotate limiting bracket B2. During this process, limiting bracket B2 will move the scale 21 towards the storage slot 16. At this time, the rotation angle of limiting bracket B2 can be known by the scale on the scale 21, which can be used to adjust the bending angle according to the required bending angle of the wire. The bending angle is adjusted to change the angle of the limiting frame B2. After adjustment, the bent wire is inserted into the limiting port 11 of the limiting frame B2 to complete the limiting of the wire. A rubber pad is provided on the inner wall of the storage groove 16. The rubber pad increases the friction between the inner wall of the storage groove 16 and the scale 21. After the limiting frame B2 is rotated, the friction between the rubber pad and the scale 21 limits the limiting frame B2, preventing it from rotating on its own due to its own weight.
[0030] In the embodiments of this utility model, please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8Two drive rollers 3 are rotatably connected within the mounting groove 14. A drive belt 31 is sleeved between the two drive rollers 3 within the same mounting groove 14. The drive rollers 3 have a structure that is thicker at both ends and thinner in the middle. Several evenly distributed anti-slip blocks are provided on the drive belt 31. A sleeve 32 is rotatably connected within the communicating cavity 15. One end of the sleeve 32 is fixedly connected to the drive roller 3 on the same side. An installation rod 33 is slidably connected to the end of the sleeve 32 away from the drive roller 3. An installation plate 35 is fixedly connected to the installation rod 33. 5. Several evenly distributed ring-shaped locking blocks 36 are fixedly connected to the side of the sleeve 32. A limit spring 34 is fixedly connected between one end of the mounting rod 33 and the inner wall of the sleeve 32. A knob 37 is fixedly connected to the end of the mounting rod 33 away from the sleeve 32. A limit ring 4 is fixedly connected in the communicating cavity 15. The limit ring 4 is located between the transmission roller 3 and the mounting plate 35. Several evenly distributed ring-shaped locking grooves 41 are opened on the side of the limit ring 4 near the mounting plate 35. The locking blocks 36 are all located in the corresponding slots 41.
[0031] It should be noted that: after the wire is secured in the limiting port 11, if the wire is not straightened, the mounting rod 33 can be pulled outward from the sleeve 32 by turning the knob 37. The mounting rod 33 will stretch the limiting spring 34, and the locking block 36 on the mounting plate 35 will be pulled out from the locking groove 41 on the limiting ring 4. At this time, the mounting rod 33 can drive the transmission roller 3 to rotate, and the transmission roller 3 can drive the transmission belt 31 to rotate. The transmission belt 31 can then move the wire in the limiting port 11. For fine-tuning, after straightening the wire, release the knob 37. At this time, the tension on the limiting spring 34 disappears and it begins to rebound, driving the mounting rod 33 to move into the sleeve 32. The mounting rod 33 also drives the mounting plate 35 to move, causing the locking block 36 to re-lock into the slot 41. This completes the limiting work of the transmission roller 3. At this time, the wire in the limiting port 11 can be limited by the limited transmission belt 31 and its built-in anti-slip block, so that the wire will not move on its own due to external force.
[0032] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 4 Limiting grooves 13 are provided on both sides of the inner wall of the bayonet 12 of the limiting frame A1 and the limiting frame B2. A baffle 5 is slidably connected in the limiting groove 13. Several fixing springs 51 are fixedly connected between the baffle 5 and the inner wall of the limiting groove 13 on the same side.
[0033] It should be noted that the side of the baffle 5 away from the limiting port 11 has an arc surface, while the side of the baffle 5 near the limiting port 11 is flat. When bundling the wires, the wires are pressed tightly against the arc surface of the baffle 5 and squeezed into the limiting port 11. At this time, the arc surface changes the direction of pressure, causing the baffle 5 to move into the limiting groove 13 and compress the fixing spring 51. At this time, the baffle 5 opens, and the wire can be inserted into the limiting port 11 through the latch 12. After the wire enters the limiting port 11, the fixing spring 51 begins to rebound, and the baffle 5 extends out of the limiting groove 13. At this time, the two baffles 5 work together to seal the latch 12, preventing the wire from falling out of the limiting port 11 through the latch 12. Since the side of the baffle 5 near the limiting port 11 is flat, it also prevents the wire from being squeezed open by external forces, thus preventing the latch 12 from losing its sealing effect.
[0034] In the embodiments of this utility model, please refer to Figure 3 and Figure 5 The limiting frame A1 is fixedly connected to a hook 17 on the side away from the bayonet 12. The limiting frame A1 is provided with a fixing plate 6 on the side close to the hook 17. Several rows of evenly distributed hanging rings 61 are fixedly connected to the fixing plate 6. The limiting frame A1 is hung on the hanging rings 61 by the hook 17.
[0035] It should be noted that when installing the limit bracket A1, first fix the fixing plate 6 to the designated position on the inner wall of the electrical cabinet with screws. Then, according to specific needs, hang the limit bracket A1 on the appropriate hanging ring 61 with the hook 17 to fix the limit bracket A1. At this time, the hanging ring 61 below the hanging ring 61 fits against the outer wall of the limit bracket A1 to support the limit bracket A1, so that the limit bracket A1 is always in a vertical position, which allows it to better bundle the wires. The fixing plate 6 makes it more convenient to change the position of the limit bracket A1 when needed, and the limit bracket A1 can be directly hung on other designated hanging rings 61.
[0036] The working principle of the wiring harness mechanism for electrical cabinets provided by this utility model is as follows:
[0037] First, fix the fixing plate 6 to the designated position on the inner wall of the electrical cabinet with screws. Then, according to specific needs, hang the limit frame A1 on the hanging ring 61 in the appropriate position with the hook 17 to fix the limit frame A1. At this time, the hanging ring 61 below the hanging ring 61 is in contact with the outer wall of the limit frame A1 to support the limit frame A1, so that the limit frame A1 is always in a vertical state, so that it can effectively bundle the wires.
[0038] Then the wires can be bundled, with the wires pressed tightly against the arc surface of the baffle 5 and squeezed into the limiting port 11. At this time, the direction of pressure is changed by the arc surface, causing the baffle 5 to move into the limiting groove 13 and squeeze the fixing spring 51. At this time, the baffle 5 opens, and the wire can be inserted into the limiting port 11 through the bayonet 12. After the wire enters the limiting port 11, the fixing spring 51 begins to rebound, and the baffle 5 extends out of the limiting groove 13. At this time, the bayonet 12 can be sealed by the cooperation of the two baffles 5.
[0039] If it is necessary to bend the wire, first put the wire into the limiting opening 11 through the clamp 12 of the limiting frame A1, and then manually rotate the limiting frame B2. During this process, the limiting frame B2 will drive the scale 21 to move into the storage slot 16. At this time, the rotation angle of the limiting frame B2 can be known by the scale on the scale 21. The angle of the limiting frame B2 can be adjusted according to the bending angle required for the wire. After the adjustment is completed, the bent wire is put into the limiting opening 11 of the limiting frame B2 to complete the limiting work of the wire.
[0040] After the wire is secured in the limiting port 11, if the wire is not straightened, the mounting rod 33 is pulled outward from the sleeve 32 by turning the knob 37. The mounting rod 33 will stretch the limiting spring 34, and the locking block 36 on the mounting plate 35 will be pulled out from the locking groove 41 on the limiting ring 4. At this time, the mounting rod 33 can drive the transmission roller 3 to rotate, and the transmission roller 3 can drive the transmission belt 31 to rotate. The transmission belt 31 can then move the wire in the limiting port 11, thereby performing micro-movement. When adjusting the work, after straightening the wire, release the knob 37. At this time, the tension on the limit spring 34 disappears and begins to rebound, driving the mounting rod 33 to move into the sleeve 32. The mounting rod 33 also drives the mounting plate 35 to move, so that the locking block 36 is locked back into the slot 41. This completes the limiting work of the transmission roller 3. At this time, the wire in the limiting port 11 can be limited by the limited transmission belt 31 and its own anti-slip block, so that the wire will not move on its own due to external force.
[0041] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0042] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
