Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of frequency converters, specifically to an anti-interference structure for frequency converter components. Background Technology
[0002] A frequency converter is a component used to control motors or other electric equipment, adjusting the speed of the equipment by changing the power supply frequency. A search revealed Chinese patent CN221042631U, which discloses an anti-interference structure for a frequency converter. This invention solves the problem of existing frequency converters being inconvenient to wind up the connecting lines while isolating interference. This invention uses a support frame, connecting plate, winding rod, protrusion, and moving plate. First, the moving plate is moved outward along the sliding direction of the slider in the groove, thus compressing the spring. At this time, the initial groove inside the moving plate disengages from the protrusion. Then, the winding rod is rotated to make it vertical. The wire is then passed through the wire groove, the rubber sheet opens, and the wire is wound around the outside of the winding rod. Finally, the above steps are reversed to make the winding rod horizontal, with the protrusion and groove engaging. Furthermore, three sets of winding assemblies are set at the bottom of the partition plate, with different heights, which avoids mutual interference between the wires wound on the outside of the three sets of winding assemblies, achieving anti-interference for the wiring. However, when this interference structure is in use, different wires are wound around winding rods at different heights, but the connecting wires are all exposed to the outside, which still causes mutual interference. At the same time, the winding roller cannot rotate. When the connecting wire is wound on the winding roller, the position of the connecting wire cannot be moved when the connecting wire needs to be adjusted, which reduces the efficiency of the device. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides an anti-interference structure for frequency converter components. This solves the problem that when different wires are wound around winding rods at different heights during use, the connecting wires are all exposed and still cause mutual interference. At the same time, the winding rollers cannot rotate, and when the connecting wires are wound on the winding rollers, their positions cannot be moved when adjustments are needed, thus reducing the efficiency of the device.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference structure for a frequency converter component, comprising a shielding box and an anti-interference box. A placement plate is fixedly installed inside the shielding box, and a frequency converter component and a filter are fixedly installed on the upper end of the placement plate. A door panel is hinged to the front end of the shielding box. The anti-interference box is fixedly installed at equal intervals at the bottom of the shielding box. A cover plate is hinged to the right side of the anti-interference box. Second connection holes are provided inside both the top and bottom surfaces of the anti-interference box. A winding roller is rotatably connected inside the anti-interference box, and a winding groove is provided inside the side wall of the winding roller.
[0005] Preferably, the placement plate has through holes inside, and the top surface of the shielding box has first connection holes at equal intervals. The positions of the first connection holes correspond to the second connection holes on the anti-interference box, so as to facilitate the internal connection wires to enter the interior of the anti-interference box.
[0006] Preferably, the two side walls inside the anti-interference box are provided with connecting grooves, and connecting rods are fixedly installed at both ends of the winding roller. Connecting blocks are fixedly connected to the ends of the connecting rods. The connecting blocks are slidably connected to the inside of the connecting grooves through the winding rollers, thereby facilitating the removal of the winding rollers and the winding of the connecting wires.
[0007] Preferably, support rods are symmetrically fixedly installed on both sides of the bottom surface of the anti-interference box, and a baffle is fixedly connected to the bottom of the support rod, so as to facilitate the protection of the position of the second connection hole.
[0008] Preferably, the size of the connecting block matches the size of the connecting groove, thereby facilitating the complete insertion of the connecting block into the interior of the connecting groove, allowing the cover plate to abut against its sidewalls, and preventing the winding roller from shaking.
[0009] Preferably, both ends of the connecting block are horizontal to the side wall of the winding roller, thereby preventing the winding roller from obstructing the opening and closing of the cover plate.
[0010] This invention provides an anti-interference structure for a frequency converter component. It has the following beneficial effects:
[0011] 1. The anti-interference structure of the frequency converter component allows the winding roller to rotate inside the anti-interference box when using the anti-interference structure of the frequency converter component, which facilitates the adjustment of the length of the installed connecting wire.
[0012] 2. The anti-interference structure of this frequency converter component, when using the anti-interference structure of the frequency converter component, strengthens the anti-interference effect between adjacent connection lines by placing the connection lines separately through a separately set anti-interference box.

A door panel 2 is hinged to the front end of the shielding box 1. The anti-interference box 3 is fixedly installed at equal intervals at the bottom of the shielding box 1. A cover plate 6 is hinged to the right side of the anti-interference box 3. Second connection holes 15 are provided inside both the top and bottom surfaces of the anti-interference box 3. A winding mechanism is rotatably connected inside the anti-interference box 3. The winding roller 11 has a winding groove 12 inside its side wall. Support rods 4 are symmetrically fixed on both sides of the bottom surface of the anti-interference box 3. A baffle 5 is fixedly connected to the bottom of the support rod 4. When connecting the connecting wire, the connecting wire passes through the bottom side wall of the shielding box 1 and enters the interior of the anti-interference box 3 through the second connecting hole 15, so that the connecting wire is wound on the winding roller 11, or the connecting wire is first wound on the winding roller 11 and then installed, which makes it easy to adjust the length of the connecting wire that needs to be installed.
[0022] Example 2
[0023] To facilitate the placement and use of the connecting cable, in this embodiment, as follows: Figure 3-5As shown, the placement plate 7 has through holes 8 inside, and the top surface of the shielding box 1 has first connecting holes 10 evenly spaced inside. The positions of the first connecting holes 10 correspond to the second connecting holes 15 on the anti-interference box 3. The connecting wires are passed through the through holes 8 and enter the first connecting holes 10. The two side walls inside the anti-interference box 3 are provided with connecting grooves 13. Connecting rods 17 are fixedly installed at both ends of the winding roller 11, and connecting blocks 14 are fixedly connected to the ends of the connecting rods 17.

Connecting rods 17 are fixedly installed at both ends of the winding roller 11. Connecting blocks 14 are fixedly connected to the ends of the connecting rods 17. The connecting blocks 14 are slidably connected to the inside of the connecting grooves 13 through the winding roller 11. The size of the connecting blocks 14 matches the size of the connecting grooves 13. The side walls at both ends of the connecting blocks 14 are horizontal with the side walls of the winding roller 11, so that they enter the inside of the anti-interference box 3 in sequence. The anti-interference box 3 contains a separate connecting wire, which can enhance the anti-interference effect between adjacent connecting wires.
[0024] It should be noted that in this embodiment, when using the anti-interference structure of the frequency converter component, such as Figure 1-5 As shown, when connecting the connecting wires, the cover plate 6 is opened, the winding roller 11 is taken out, and the connecting wires to be connected are wound around the winding roller 11. After winding, the connecting wires are passed through the second connecting hole 15 and into the first connecting hole 10, and then connected to the frequency converter through the through hole 8. Then, the length of the connecting wires is taken according to the length to be connected at the other end of the connecting wires. Then, the winding roller 11 is placed inside the anti-interference box 3. The anti-interference box 3 can protect one connecting wire placed inside it, which can enhance the anti-interference effect between adjacent connecting wires.
