Its high heat dissipation characteristic means that it can effectively dissipate the heat generated during operation, avoiding faults or damage caused by overheating. This design enables the vector frequency converter to maintain stable performance during long-term high-load operation and extends the service life of the equipment.

[0003] When wiring a high heat dissipation vector frequency converter, the cover plate needs to be disassembled. However, the cover plate is snap-connected to the main unit through a buckle, and a large force is required to disassemble the cover plate. But during the disassembly process, the buckle is easily damaged, making the cover plate unable to be reinstalled on the main unit. Content of the Utility Model

[0014] 1. When disassembling the cover plate of this device, press down the connecting rod to make the two moving blocks move downward. The movement of the moving blocks causes the socket column to move from the inside of the insertion hole to the outside. At the same time, the downward movement of the moving blocks squeezes the stainless steel spring through the fixed block. When the moving blocks cannot move downward anymore, pull the cover plate downward through the connecting rod to separate the cover plate from the vector frequency converter main unit. In this way, the disassembly of the cover plate is completed. When reinstalling, press down the connecting rod until it cannot move, align the clamping block with the L-shaped card slot, push the cover plate until it coincides with the vector frequency converter main unit, and release the connecting rod to make the stainless steel spring release its elastic force. The socket column is inserted into the inside of the insertion hole, and at the same time, the clamping block is clamped inside the L-shaped card slot. In this way, the installation of the cover plate and the vector frequency converter main unit is completed. Using this design can effectively avoid the situation of damaging the buckle due to excessive force when disassembling the cover plate, ensure the integrity of the buckle, and improve the convenience and efficiency of operation.

[0015] 2. The vector frequency converter main unit is wired through the wiring terminals at the lower front position. Multiple elastic card slots are distributed at the lower position of the wiring terminals. Each elastic card slot corresponds to the wiring hole in the wiring terminal.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The utility model provides as Figure 1-6A high heat dissipation vector frequency converter shown in the figure includes a vector frequency converter main unit 1, which is controlled by a control panel 5 at the upper front position. An insertion hole 8 is provided at the inner position of the vector frequency converter main unit 1. L-shaped card slots 13 are provided on the inner wall of the vector frequency converter main unit 1 at the left and right positions. A cover plate 6 is installed at the front end position of the vector frequency converter main unit 1 through the L-shaped card slots 13 and the insertion hole 8. Slide grooves 10 are provided at the left and right ends of the cover plate 6. A stainless steel spring 18 is fixed at the inner position of the slide grooves 10. The cover plate 6 is clamped with moving blocks 9 at the left and right positions through the slide grooves 10. The two moving blocks 9 are connected by a connecting rod 7 fixed at the front end position. Clamping blocks 16 and fixing blocks 17 are respectively fixed at the left and right positions of the inner wall of the moving block 9. A socket column 14 is fixed at the upper end position of the moving block 9, and at the same time, the socket column 14 is sleeved at the inner position of the cover plate 6. A wiring terminal 11 for wiring is provided at the front end position of the vector frequency converter main unit 1. A fixing plate 15 is fixed at the lower front position of the vector frequency converter main unit 1. A plurality of elastic card slots 12 are distributed at the front end position of the fixing plate 15.

[0025] The wiring terminal 11 is connected to an AC input power supply and an AC motor. The AC power supply is input into the vector frequency converter main body, and the AC signal is converted into a DC signal. The DC signal passes through the inverter module in the vector frequency converter main body and is converted into an AC signal with adjustable frequency and adjustable amplitude to drive the AC motor. The user operates the control panel 5 to send instructions, which are transmitted to the inverter module. The inverter converts the DC power into an AC signal with variable frequency and variable amplitude again to drive the motor. By adjusting the output frequency and voltage, the vector frequency converter realizes precise control of the motor.

[0026] As Figure 1 and Figure 3 shown, heat dissipation holes 4 are provided at the upper end, left and right positions of the vector frequency converter main unit 1. A back plate 3 is installed at the rear end position of the vector frequency converter main unit 1. A heat sink 2 for dissipating heat from the vector frequency converter main unit 1 is installed at the rear end position of the back plate 3. The control panel 5 controls the control unit inside the vector frequency converter main unit 1. A display screen is provided at the front end position of the control panel 5. The control panel 5 can perform forward rotation switching and reverse rotation switching through the control at the front end position. The vector frequency converter main unit 1 is wired through the wiring terminal 11. A plurality of elastic card slots 12 are distributed at the front end position of the fixing plate 15, and the elastic card slots 12 correspond to the wiring terminal 11.

[0027] The main unit 1 of the vector frequency converter is wired through the wiring terminal 11 at the lower front position. A plurality of elastic card slots 12 are distributed at the lower position of the wiring terminal 11. Each elastic card slot 12 corresponds to the wiring hole in the wiring terminal 11. When wiring, the wire is clamped inside the elastic card slot 12, making the overall wiring more compact and orderly, and reducing the clutter of cables.

[0028] As Figure 4 and Figure 6 shown, the connecting rod 7 can press down on the two moving blocks 9. When the moving blocks 9 move downward, the fixed block 17 squeezes the stainless steel spring 18. The cover plate 6 is installed with the main unit 1 of the vector frequency converter, so that the socket column 14 is inserted into the insertion hole 8, and the clamping block 16 is clamped inside the L-shaped card slot 13.

[0029] Press down the connecting rod 7 to make the two moving blocks 9 move downward. The movement of the moving blocks 9 causes the socket column 14 to move from the inside of the insertion hole 8 to the outside. At the same time, the moving blocks 9 move downward to squeeze the stainless steel spring 18 through the fixed block 17. When the moving blocks 9 cannot move downward anymore, pull down the cover plate 6 through the connecting rod 7 to separate the cover plate 6 from the main unit 1 of the vector frequency converter, thus completing the disassembly of the cover plate 6. When reinstalling, press down the connecting rod 7 until it cannot move, align the clamping block 16 with the L-shaped card slot 13, push the cover plate 6 until it coincides with the main unit 1 of the vector frequency converter, and release the connecting rod 7 to make the stainless steel spring 18 release its elastic force. The socket column 14 is inserted into the insertion hole 8, and at the same time, the clamping block 16 is clamped inside the L-shaped card slot 13, thus completing the installation of the cover plate 6 and the main unit 1 of the vector frequency converter.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
