Technical Field

[0001] This utility model relates to the field of frequency converter installation technology, specifically to a frequency converter mounting bracket with cable management function. Background Technology

[0002] A frequency converter (VFD) is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of its power supply. A VFD mainly consists of a rectifier (AC to DC), filter, inverter (DC to AC), braking unit, drive unit, detection unit, and microprocessor unit. The VFD adjusts the output voltage and frequency by switching its internal IGBTs, providing the required power voltage according to the motor's actual needs, thereby achieving energy saving and speed regulation. In addition, VFDs have many protection functions, such as overcurrent, overvoltage, and overload protection. With the continuous improvement of industrial automation, VFDs have been widely used.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 The inverter mounting bracket shown includes:

[0026] Fixed frame 1;

[0027] The mounting plate 2 for mounting the frequency converter is installed inside the fixed frame 1;

[0028] It also includes a cable management rack 3 that is movable within the fixed frame 1. The cable management rack 3 is mounted on the fixed frame 1 via an installation component 5. The cable management rack 3 has multiple sets of cable grooves 4 for binding the cable bundles.

[0029] The mounting component 5 includes a mounting frame 51, which has multiple sets of through holes 6. A mounting bolt 7 is movably disposed in the through hole 6. One end of the mounting bolt 7 passes through the cable management frame 3 and is fixed with a mounting nut 8.

[0030] With the cooperation of mounting bolts 7 and mounting nuts 8, the cable management rack 3 can be easily installed on the mounting frame 51. At the same time, the orientation of the cable management rack 3 can be adjusted to meet the constraint requirements of wire harnesses with different orientations. Meanwhile, the cable management rack 3 is adjustablely installed on the fixed frame 1 by the mounting component 5. The cable management rack 3 can be fixed as needed to facilitate the restriction of wire harnesses on the frequency converter and avoid excessive wire harnesses that lead to mess.

[0031] Among them, such as Figure 3 As shown:

[0032] The mounting assembly 5 also includes two sets of movable latches 52. Supporting springs 53 are fixed to the inner sides of both ends of the mounting frame 51. One end of the movable latch 52 passes through the inner cavity of the mounting frame 51 and is fixedly connected to the movable end of the supporting spring 53. The movable latch 52 is connected to the mounting frame 51 through the supporting spring 53, so that the movable latch 52 can extend outward from both ends of the mounting frame 51 to extend the length of the mounting frame 51. The movable latch 52 can also be used to fix and limit the mounting frame 51 to ensure the stability of the cable management frame 3.

[0033] Furthermore, such as Figure 1 As shown:

[0034] The fixed frame 1 has opposing slots 9, and the movable block 52 is engaged in the inner cavity of the slot 9. The side of the slot 9 is rectangular.
