[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 This utility model provides an embodiment of a cable routing structure for a frequency converter cabinet, comprising a frequency converter cabinet 1, a groove 4 on the front end face of the frequency converter cabinet 1, a cabinet door 5 on the inner side of the groove 4, three sets of heat dissipation slots 2 evenly arranged on both sides of the outer surface of the frequency converter cabinet 1, a dustproof net 3 installed on the inner side of the heat dissipation slots 2, two partitions 11 evenly installed on the inner side of the frequency converter cabinet 1, a through groove 10 on the rear end face of the partition 11, three strip grooves 12 evenly arranged on the rear end face of the frequency converter cabinet 1, a baffle 6 movably installed on the inner side of the through groove 10 through a detachable mechanism 7, a terminal block 8 installed on the front end face of the baffle 6, and multiple wiring holes 9 evenly arranged on the upper end face of the terminal block 8.

[0022] Cabinet door 5 is connected to groove 4 by a hinge. A handle is installed on the front end of cabinet door 5, which can be used to open the cabinet door.

[0023] Two partitions 11 divide the groove 4 into three parts, from top to bottom: the control area, the main circuit area, and the wiring area. This physically isolates the high-voltage and dangerous main circuit from the control and wiring areas that personnel frequently need to access, greatly reducing the risk of accidental contact.

[0024] The detachable mechanism 7 includes a slide plate 703, which is installed on both sides of the strip groove 12 via a slide groove 701. The slide plate 703 is movably connected to the inner wall of the slide groove 701 via a first spring 702.

[0025] Two sliding plates 703 have locking blocks 704 installed on the top and bottom of opposite sides of their outer surfaces. The front end of the locking block 704 has a second inclined surface 709. Both sides of the outer surface of the baffle 6 have locking grooves 707. The sliding groove 701 is connected to the strip groove 12 through a connecting groove. The locking block 704 can be moved by sliding the sliding plate 703.

[0026] The locking block 704 passes through the connecting groove and can be locked into the inside of the slot 707. The front sides of the baffle 6 are provided with first inclined surfaces 708. The front sides of the inner wall of the strip groove 12 are each provided with a horizontal plate 705. The rear end face of the horizontal plate 705 is provided with a second spring 706.

[0027] The size of the terminal block 8 is smaller than the inner side of the through groove 10, and the terminal block 8 can be inserted into the inner side of the through groove 10.

[0028] The cable routing structure for this inverter cabinet utilizes two partitions 11 to divide the groove 4 from top to bottom into a control area, a main circuit area, and a wiring area. This physically isolates the high-voltage, hazardous main circuit from the control and wiring areas that personnel frequently come into contact with, greatly reducing the risk of accidental contact. Furthermore, three sets of terminal blocks 8 are positioned inside the control, main circuit, and wiring areas, respectively, facilitating subsequent cable routing. A strip groove 12, a baffle 6, and a detachable mechanism 7 securely connect the terminal blocks 8 to the detachable baffle 6, with the baffle 6 movably mounted on the strip groove 12. When it is troublesome to perform cable routing inside the inverter cabinet 1, the baffle 6 and terminal block 8 can be removed from the inside of the strip groove 12 through the detachable mechanism 7. The operator can then go around to the back of the inverter cabinet 1 to route the cables, and then install the baffle 6 back on the inside of the strip groove 12. This utility model, by installing the partition 11, divides the groove 4 from top to bottom into the control area, the main circuit area, and the wiring area, which greatly reduces the risk of accidental contact and facilitates the disassembly and assembly of the terminal block 8, thus making it convenient to route cables from the back of the inverter cabinet 1, and is easy to use.
