[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5 This embodiment of a PLC control cabinet wiring device includes a vertical slide rail assembly, a horizontal wiring board assembly, a flexible cable fixing assembly, and a centralized cable management assembly. The vertical slide rail assembly includes two vertical slide rails 1, each with a strip groove 11 along its vertical direction. The horizontal wiring board assembly includes a horizontal wiring board 2, with sliders 21 fixedly installed at both ends. The sliders 21 are slidably connected to the strip grooves 11 on the vertical slide rails 1. Multiple wire grooves 22 are evenly distributed on the upper surface of the horizontal wiring board 2. The flexible cable fixing assembly includes... Multiple flexible clips 3 are installed on both sides of the cable tray 22. Each flexible clip 3 consists of a fixed base 31, a movable base 32, and an elastic structure. The fixed base 31 is fixedly installed on the horizontal wiring board 2 and located on the side of the cable tray 22. The top of the movable base 32 is connected to the elastic structure. The cable centralized management component is a junction box 4. The junction box 4 has multiple inlet holes 41 on its side and an outlet hole 42 on its top. A partition plate 44 extending into the top of the junction box 4 is inserted into it. Each inlet hole 41 and outlet hole 42 corresponds to a cable tray 22.

[0025] The partition plate 44 divides the inside of the junction box 4 into multiple independent junction cavities. Each junction cavity corresponds to a cable inlet 41. The marking part 43 corresponding to the cable inlet 41 can mark the cable name so that maintenance personnel can easily identify it.

[0026] When installing the wiring device for this PLC control cabinet, first, fix the two vertical slide rails 1 on the two side walls inside the PLC control cabinet, fix the junction box 4 on the bottom inside the cabinet, and introduce the external cables into the corresponding junction box 4 through the side inlet holes 41. In the junction box, perform preliminary arrangement of the cables. Then, lead the cables out from the top outlet holes 42 to the cable tray 22 of the horizontal wiring board 2. Use the elastic clips 3 to firmly fix the cables in the cable tray 22 to complete the entire wiring process.

[0027] The vertical slide rail 1 is also evenly distributed with multiple positioning holes 12, and the slider 21 is provided with positioning bolts 23. According to the actual wiring requirements, the height position of the horizontal wiring plate 2 can be adjusted by sliding it up and down. After the adjustment is in place, the positioning bolts 23 on the slider 21 are tightened to make it cooperate with the corresponding positioning holes 12 on the vertical slide rail 1, thereby fixing the horizontal wiring plate 2. Multiple wire grooves 22 are evenly opened on the upper surface of the horizontal wiring plate 2. The wire grooves 22 are used to accommodate cables and play a preliminary positioning and separation role for the cables.

[0028] The elastic clip 3 consists of a fixed base 31, a movable base 32, and an elastic structure. The elastic structure includes a hook plate 33, a guide block 34, a guide groove 35, and a spring 36. By pulling the hook plate 33 away from the fixed base 31, the movable base 32 is moved, allowing the cable to be placed into the cable tray 22. A rotating shaft 37 and a locking block 38 are also provided. The rotating shaft 37 can drive the locking block 38 to rotate horizontally around its axis. When placing the cable between the fixed base 31 and the movable base 32, the movable base 32 is first pulled away from the fixed base 31, rotating the locking block 38 to the side corresponding to the hook plate 33, causing the locking block 38 to engage with the locking slot 39, limiting the hook plate 33 and preventing the movable base 32 from moving back. After the cable is placed into the cable tray 22 and tidied, the locking block 38 is rotated to the other side and disengaged from the locking slot 39. Under the expansion of the spring 36, the movable base 32 moves quickly to secure the cable.

[0029] The cable enters the corresponding cable collection chamber from the outside of the cabinet through the inlet hole 41. After initial arrangement in the cable collection chamber, it is led out from the outlet hole 42 to the cable tray 22 of the horizontal wiring board 2. Rubber rings are also provided at the inlet hole 41 and the outlet hole 42. The rubber rings can seal the cable entering from the inlet hole 41 to prevent dust, moisture and other substances from entering the inside of the cable collection box 4. At the same time, they can also play a certain role in shock absorption and reduce the wear of the cable caused by vibration.

[0030] In summary, this PLC control cabinet wiring device, through the cable trays 22 on the horizontal wiring board 2, as well as the junction box 4 and the partition plate 44, can achieve systematic classification and centralized management of cables, making the cable layout neat and orderly, facilitating the quick identification and positioning of cables by staff during later maintenance and repair, and significantly improving maintenance efficiency; by setting the vertical slide rail 1, slider 21, positioning hole 12 and positioning bolt 23, the height position of the horizontal wiring board 2 can be flexibly adjusted according to actual wiring needs, improving the applicability of the wiring device.

[0031] Furthermore, by setting up an elastic clip 3, and utilizing structures such as spring 36 and clip 38, the cable can be firmly fixed. Compared with traditional cable ties or simple clamps, this can effectively prevent the cable from becoming loose or tangled during long-term use, ensuring the accuracy of signal transmission and reducing the probability of safety problems such as short circuits.
