By setting the second guide groove 5 and the second guide block 51, the second guide block 51 can slide horizontally inside the second guide groove 5, so that the limiting protrusion 46 can be guided in the horizontal direction, so that the limiting protrusion 46 can keep sliding in the horizontal direction. By setting the push-pull plate 52, when the two return-shaped fixed frames 1 are disassembled, the push-pull plate 52 can be manually pushed to move horizontally, and the push-pull plate 52 disengages the limiting protrusion 46 from the limiting groove 48. At the same time, the spring rod 49 is in a retracted state.

[0035] The present invention also provides a wiring method for a wiring arrangement device for a power distribution cabinet, comprising the following steps: S1. Height adjustment First, the fixing screw 34 is disengaged from the sliding block 33, so that the sliding block 33 is in an active state, and the height of the U-shaped wiring box 21 is adjusted so that the height of the threading slot 23 corresponds to the interface of the power component; S2, wiring harness assembly The U-shaped fixing frame 1 is fixedly installed in the power distribution cabinet through the L-shaped angle iron 11, the mounting hole 12 and the matching bolts, and the U-shaped fixing frame 1 is located in front of the power components, and then the wiring harness groups of the power distribution cabinet are placed in multiple U-shaped wiring boxes 21 respectively, and the wiring harness groups in the U-shaped wiring boxes 21 are limited by the arc-shaped pressing plate 27 and the box cover 24, so that the wiring harness groups are separated and neatly arranged in the U-shaped wiring boxes 21; S3. Splicing By vertically plugging the wedge block 41 into the insertion slot 42 and cooperating the limiting protrusion 46 with the limiting groove 48, the wedge block 41 is limited and fixed, and the two circular fixing frames 1 can be vertically spliced ​​to adapt to distribution cabinets of different heights.

[0036] Working principle: When it is necessary to arrange the wiring harness in the power distribution cabinet, the operator first fixes the circular fixing frame 1 in the power distribution cabinet through the L-shaped angle iron 11, the mounting hole 12 and the matching bolts. The fixed circular fixing frame 1 is located in front of the power components of the power distribution cabinet; Then, the operator manually rotates the two corresponding hexagonal handles 36 in a counterclockwise direction to disengage the two fixing screws 34 from the corresponding threaded holes 35. At this time, the two sliding blocks 33 are in an active state. Then, the operator manually pulls the U-shaped wiring box 21 up and down to make the lifted U-shaped wiring box 21 located in front of a row of power components, so that the threading slots 23 correspond horizontally to the interfaces of the power components. Then, the wiring harness of the power distribution cabinet is placed in the U-shaped wiring box 21, and the two ends of the wiring harness enter the two adjacent arc-shaped clamping plates 27. The two adjacent arc-shaped clamping plates 27 limit the wiring harness. When the connection between the interface of a single cable in the wiring harness and the power component is completed, the box cover 24 is buckled on the U-shaped wiring box 21, thereby conveniently realizing the wiring operation of the wiring harness of the power distribution cabinet, improving the convenience of operation, and at the same time, the wiring harness is separated and neatly arranged in the power distribution cabinet, which is convenient for the maintenance of the wiring harness. When the height dimension of the power distribution cabinet is longer, the operator places another circular fixing frame 1 vertically on the top of a circular fixing frame 1 (a circular fixing frame 1 has been fixed in the power distribution cabinet), and vertically inserts the two wedge blocks 41 into the corresponding plug-in slots 42. In the process of vertically inserting the wedge block 41 into the plug-in slot 42, one side of the wedge block 41 contacts and fits with the second inclined surface 47. The downward pressure of the wedge block 41 causes the limiting protrusion 46 to slide horizontally toward one side of the active cavity 45. The limiting protrusion 46 causes the spring rod 49 to contract. When the limiting protrusion 46 corresponds horizontally to the limiting groove 48, the spring rod 49 resets, extends and pushes the limiting protrusion 46 to slide horizontally in the opposite direction. The spring rod 49 causes the limiting protrusion 46 to insert into the limiting groove 48. The limiting protrusion 46 fixes the wedge block 41, thereby conveniently realizing the splicing and fixation of the two circular fixing frames 1, and thus facilitating the wiring operation of power distribution cabinets of different heights.

Height adjustment First, the fixing screw (34) is disengaged from the sliding block (33), so that the sliding block (33) is in an active state, and the height of the U-shaped wiring box (21) is adjusted so that the height of the threading slot (23) corresponds to the interface of the power component; S2, wiring harness assembly The circular fixing frame (1) is fixedly installed in the power distribution cabinet by means of L-shaped angle irons (11), mounting holes (12) and matching bolts, and the circular fixing frame (1) is located in front of the power components. Then, the wiring harness groups of the power distribution cabinet are respectively placed in a plurality of U-shaped wiring boxes (21), and the wiring harness groups in the U-shaped wiring boxes (21) are limited by means of arc-shaped clamping plates (27) and box covers (24), so that the wiring harness groups are separated and neatly arranged in the U-shaped wiring boxes (21); S3. Splicing By vertically plugging the wedge block (41) into the plug slot (42) and cooperating the limiting protrusion (46) with the limiting groove (48), the wedge block (41) is fixed in position, and two circular fixing frames (1) can be vertically spliced ​​to adapt to distribution cabinets of different heights.
