Description

Technical Field

[0001] This utility model relates to the field of frequency converter manufacturing and processing technology, and in particular to a frequency converter wiring assembly. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of the power supply. As a core device in industrial automation for achieving motor speed regulation and energy control, the wiring components of a frequency converter are used to organize and fix various cables such as input and output power lines, control lines, and communication lines, playing a crucial role in the stability of frequency converter operation and the efficiency of subsequent maintenance.

[0003] However, existing inverter wiring components mostly use simple methods such as cable ties or single cable trays for binding, which makes it difficult to effectively classify and manage cables of different types and diameters. Power lines and control lines are prone to serious electromagnetic signal interference due to spatial intersections. At the same time, there is a lack of convenient initial positioning and quick debugging structures. Later maintenance requires repeated disassembly, which is time-consuming and labor-intensive. The cable routing is also not accurately guided, which makes it easy for cables to become tangled and cross, further increasing the difficulty of maintenance and the risk of equipment failure. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a frequency converter wiring assembly, which aims to improve the problems that traditional frequency converter wiring equipment cannot meet the requirements of flexible wiring and anti-interference in complex working conditions, as well as the lack of rapid debugging and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a frequency converter wiring assembly, including a frequency converter body, a flip cover on the outer wall of the frequency converter body, multiple step-shaped limiting blocks inside the frequency converter body, multiple sliding columns slidably connected to the inner wall of each limiting block, bolts threadedly connected to the inner wall of each sliding column, a connecting block on the outer wall of each sliding column, a fixing block on the inner wall of each connecting block, multiple limiting posts symmetrically arranged on both sides of each fixing block, a slider at one end of each of the multiple limiting posts, multiple springs on the side of the fixing block and the slider that are close to each other, multiple wire grooves on the outer wall of each limiting block located below the corresponding connecting block, wires slidably connected to the inner wall of each wire groove, and an opening and closing assembly on the inner wall of the frequency converter body.

[0006] The above technical solution involves: using a flip cover to protect the internal wiring; using a limiting block to physically layer and classify the wires to reduce signal interference; pushing the connecting block to move the sliding column to fix the wire's connection end; and simultaneously moving the slider to slide, which, under the spring's rebound, engages with the limiting block to complete the initial fixation. Then, rotating the bolt further tightens the wire to prevent it from vibrating and loosening. Squeezing the slider can release the lock, achieving temporary fixation to avoid repeated disassembly and assembly, saving time and improving efficiency.

[0007] Preferably, the opening and closing assembly includes a threaded rod, which is threadedly connected to the inner wall of the inverter body. One end of the threaded rod is provided with a knob. The outer wall of the flip cover is provided with a locking hole and multiple locking blocks. The outer wall of the inverter body is provided with multiple locking slots.

[0008] Preferably, the inverter body has multiple positioning blocks arranged in parallel inside, the positioning blocks are slidably connected to the inner wall of the inverter body, the inner wall of the inverter body has multiple sliding grooves, and the surface of each positioning block has multiple positioning slots.

[0009] Preferably, the outer wall of the inverter body is provided with multiple limiting grooves, and the wire is slidably connected to the inner wall of the limiting groove.

[0010] Preferably, the plurality of connecting blocks and sliders are slidably connected to the inner wall of the limiting block.

[0013] Preferably, the positioning block is slidably connected to the inner wall of the groove, and the wire is slidably connected to the inner wall of the positioning groove.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the combination of components such as limiting blocks, sliding columns and connecting blocks enables physical layering of different types of wires to reduce signal interference, quickly and initially fix the wires, facilitate debugging and avoid repeated disassembly, prevent wires from loosening due to vibration, guide the orderly arrangement of wires while avoiding tangling, thereby facilitating later expansion and maintenance, and ultimately achieving orderly arrangement, stable fixation, anti-interference and protection of wires in one integrated system. It has strong adaptability and convenient maintenance, thereby improving the safety and reliability of inverter wiring.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0019] Reference Figure 1 and Figures 3-5 This utility model provides an embodiment of a frequency converter wiring assembly, including a frequency converter body 1, a flip cover 2 on the outer wall of the frequency converter body 1, a plurality of step-shaped limiting blocks 3 inside the frequency converter body 1, a plurality of sliding columns 4 slidably connected to the inner wall of each limiting block 3, a bolt 5 threadedly connected to the inner wall of each sliding column 4, a connecting block 6 on the outer wall of the sliding column 4, a fixing block 7 on the inner wall of the connecting block 6, a plurality of limiting posts 8 symmetrically arranged on both sides of the fixing block 7, a slider 10 at one end of each of the multiple limiting posts 8, a plurality of springs 9 on the side of the fixing block 7 and the slider 10 adjacent to each other, a plurality of wire grooves 11 opened on the outer wall of the limiting block 3 located below the corresponding connecting block 6, a wire 12 slidably connected to the inner wall of the wire groove 11, and an opening and closing assembly on the inner wall of the frequency converter body 1.

[0020] Specifically, the flip cover 2 can protect the internal wiring structure, and the limiting block 3 can physically separate different types of wires 12. By spatial isolation, signal interference between power lines and control lines is reduced. Pushing the connecting block 6 can cause the sliding column 4 to slide along the inner wall of the limiting block 3 to fix the wire 12 connection end. Then, rotating the bolt 5 can further tighten the wire 12 to ensure a stable fix and prevent the wire 12 from loosening due to industrial vibration. When the connecting block 6 is pushed, the slider 10 slides. Under the rebound force of the spring 9, the slider 10 is pushed to engage in the limiting block 3, completing the initial fixation of the wire 12. By squeezing the sliders 10 on both sides of the connecting block 6, the sliders 10 slide along the limiting column 8 in the connecting block 6 and squeeze the spring 9 sleeved on the limiting column 8 to release the lock between the slider 10 and the limiting block 3, allowing the slider 10 to slide into the connecting block 6. This achieves temporary fixation when quickly debugging and connecting equipment to avoid repeated disassembly and assembly, thereby saving time and improving efficiency.

[0021] Reference Figures 3-5 The inverter body 1 has multiple limiting grooves on its outer wall, and the wire 12 is slidably connected to the inner wall of the limiting groove; multiple connecting blocks 6 and sliders 10 are slidably connected to the inner wall of the limiting block 3; the limiting post 8 is slidably connected to the inner wall of the slider 10, the spring 9 is sleeved on the outer wall of the limiting post 8, and the slider 10 is slidably connected to the inner wall of the connecting block 6 and the outer wall of the fixing block 7.

[0022] Specifically, the limiting groove on the outer wall of the inverter body 1 and the wire groove 11 on the limiting block 3 form a coordinated guiding structure, which together constrains the direction of the wire 12, preventing multiple wires 12 from getting tangled, crossing, or shifting in position during wiring, further improving the neatness of the wiring and facilitating quick identification and maintenance later. The connecting block 6 and the slider 10 work together to enhance the adaptability to diverse wiring needs. The limiting post 8 provides precise axial guidance for the movement of the slider 10, and at the same time, the limiting post 8 can effectively limit the deformation trajectory of the spring 9, preventing the spring 9 from bending or shifting during compression and rebound, ensuring that the spring force of the spring 9 is stably transmitted to the slider 10, making the reset of the slider 10 smoother and more reliable, thereby ensuring the stability of the initial clamping of the wire 12. Through multiple sliding guide and constraint designs, wiring standardization, fixed reliability and operational flexibility are taken into account, effectively improving the practical performance of the inverter wiring components.

[0023] Reference Figures 1-3 The opening and closing assembly includes a threaded rod 14, which is threadedly connected to the inner wall of the inverter body 1. A knob 13 is provided at one end of the threaded rod 14. A locking hole 15 is provided on the outer wall of the flip cover 2. Multiple locking blocks 16 are provided on the outer wall of the flip cover 2. Multiple slots 17 are provided on the outer wall of the inverter body 1. The knob 13 is slidably connected to the outer wall of the flip cover 2 and the inner wall of the locking hole 15. The locking blocks 16 are engaged with the inner wall of the slots 17.

[0024] Specifically, rotating the knob 13 in the forward direction will drive the threaded rod 14 to rotate, causing the knob 13 to slide on the surface of the flip cover 2 and release the lock on the flip cover 2. At this time, rotating the flip cover 2 in the reverse direction will cause it to slide on the inner wall of the inverter body 1 to open. The knob 13 will slide along the lock hole 15 to lock or unlock, and at the same time, the locking block 16 will disengage from the inner wall of the slot 17, realizing the convenient opening and closing of the flip cover 2. When closing the flip cover 2, the locking block 16 and the slot 17 will quickly achieve initial positioning, prevent the flip cover 2 from shifting, and improve the operating efficiency. Then, rotating the knob 13 in the reverse direction will slide it on the surface of the flip cover 2, and with the limit locking of the lock hole 15, a double fixing structure will be formed to ensure that the flip cover 2 is tightly closed, effectively preventing external dust and moisture from entering the interior of the inverter body 1, protecting the wires 12 and the interface from corrosion. It takes into account the ease of operation, the accuracy of closing positioning and the reliability of protection, and significantly improves the practical performance of the wiring assembly. Example 2

[0025] Reference Figure 3 and Figure 6 This embodiment is based on the description of Embodiment 1. When additional wiring and maintenance are required, this embodiment makes improvements. Multiple positioning blocks 18 are arranged inside the inverter body 1 in a parallel state. The positioning blocks 18 are slidably connected to the inner wall of the inverter body 1. Multiple sliding grooves 19 are opened on the inner wall of the inverter body 1. Multiple positioning slots are opened on the surface of each positioning block 18. The positioning blocks 18 are slidably connected to the inner wall of the sliding grooves 19, and the wires 12 are slidably connected to the inner wall of the positioning slots.

[0026] Specifically, the positioning block 18 can form a layered classification and auxiliary support for the wires 12 in different areas. The positioning block 18 can slide along the slide groove 19 to flexibly adjust the spacing and position to adapt to the different numbers and directions of wires 12. This facilitates the adjustment of space when expanding the wiring or performing maintenance later. The slide groove 19 ensures that the positioning block 18 slides smoothly without deviation. The positioning groove on the surface of the positioning block 18, the wire groove 11, and the limiting groove on the surface of the inverter body 1 form a multi-dimensional collaborative guiding structure. The constraint of the positioning groove further standardizes the direction of a single or similar wire 12, avoiding the intersection and entanglement of multiple wires 12 in parallel areas. At the same time, it facilitates the quick differentiation of wires 12 with different functions, improving the neatness and identification efficiency of the wiring. Through the collaboration of the limiting groove, the positioning block 18, the positioning groove, and the wire groove 11, the flexibility and adaptability of the wiring are enhanced, and the orderly arrangement of the wires 12 is further ensured, providing convenience for later maintenance and expansion, thereby improving the practical performance of the equipment.

[0027] Working principle: First, rotating the knob 13 forward drives the threaded rod 14 to rotate, so that the knob 13 corresponds to the locking hole 15. Then, the flip cover 2 is slid, allowing the knob 13 to slide out of the locking hole 15 of the flip cover 2. At the same time, the locking block 16 on the outer wall of the flip cover 2 separates from the slot 17 of the inverter body 1, realizing the convenient opening and closing of the flip cover 2, which facilitates quick wiring and later maintenance. The precise cooperation between the locking block 16 and the slot 17 ensures the initial positioning when closing, improving the operating efficiency. When closing the flip cover 2, the locking block 16 is inserted into the slot 17 to achieve precise closure. At the same time, the knob 13 is inserted into the locking hole 15. Then, rotating the knob 13 in the reverse direction makes it slide on the surface of the flip cover 2 to complete the locking, forming a closed space, effectively preventing dust and moisture from entering and protecting the wires 12 and the interface. The stepped distribution of limiting blocks 3 enables physical layering of different types of wires 12, reducing signal interference. The connection end of wire 12 is placed below the sliding column 4. Then, the connecting block 6 is pushed, causing the sliding column 4 to slide against the inner wall of the limiting block 3, pressing the sliding column 4 onto the wire 12 for initial positioning. Simultaneously, the connecting block 6 drives the slider 10 to slide together. Under the restoring force of the spring 9, the slider 10 slides back along the limiting column 8, locking itself within the limiting block 3, completing the initial fixation of the wire 12. This facilitates quick and easy debugging of the connection equipment, avoiding repeated disassembly. After successful debugging, the bolt 5 is rotated to slide within the sliding column 4 and tighten the wire 12, ensuring a secure fixation and preventing loosening due to vibration. During wiring... The wires 12 are arranged in an orderly manner along the limiting grooves of the inverter body 1 and the wire grooves 11 of the limiting block 3. The wire grooves 11 can connect and classify the wires 12, which is convenient for later inspection and maintenance. The limiting grooves and wire grooves 11 cooperate to guide the wires 12 and prevent multiple wires 12 from getting tangled and crossing. The positioning block 18 can be pushed to slide in the slide groove 19 to adjust its position, which is convenient for adding wiring and maintenance later. The positioning grooves on the surface of the positioning block 18 are used to perform preliminary layering and sorting of the wires 12 to adapt to the arrangement requirements of different numbers of wires 12, further improving the standardization of wiring. It realizes the orderly arrangement, stable fixation, anti-interference and protection of the wires 12, which is highly adaptable and easy to maintain, significantly improving the safety and reliability of inverter wiring.
