[0007] By adopting the above technical solution, the external circuit enters the switch cabinet body through the sleeve and the cover and is connected to the internal components. The through holes organize the external circuits for easy identification. The connections of the external circuits of the electrical switch cabinet are not easily entangled with each other and are not easily damaged. At the same time, it is convenient for circuit maintenance.

[0008] Optionally, a plurality of slots are provided on adjacent sides of the plurality of through holes, and the plurality of slots are evenly arranged vertically. The harness assembly further comprises at least one plug-in block, which is plugged into the slot.

[0009] By adopting the above technical solution, the plug-in block enables the cover body to better distinguish the external circuits and make them easy to identify. If the external circuit fails, the identification efficiency is greatly improved.

[0010] Optionally, the cover body is evenly provided with snap-fit ​​blocks along the circumferential edge, and the sleeve is evenly provided with protrusions along the circumferential edge. The protrusions are arranged in a one-to-one correspondence with the snap-fit ​​blocks, and the protrusions are provided with snap-fit ​​grooves for the snap-fit ​​blocks to engage.

[0011] By adopting the above technical solution, the cover body is inserted into the card slot. The cover body can first allow external connections to pass through and subdivide and organize external lines, and then be inserted into the sleeve to complete the installation, which is convenient for organizing external lines and improves efficiency.

[0012] Optionally, a sliding block is provided on the protrusion, and a sliding groove is provided on the protrusion for the sliding block to slide. The sliding block slides along the length direction of the sliding groove, and the sliding groove is connected to the clamping groove. When one end of the sliding block is located in the clamping groove, the sliding block abuts against the clamping block and drives the clamping block out of the clamping groove.

[0015] By adopting the above technical solution, the anti-slip block prevents the sliding block from escaping from the anti-slip groove, so that the sliding block can always be located in the anti-slip groove, avoiding the sliding block from falling when the sleeve is disassembled.

[0016] Optionally, a contact box is provided in the switch cabinet body.

[0017] By adopting the above technical solution, the contact box can convert, transmit and distribute electrical energy between the power supply and the load, so that the electrical equipment can operate normally. At the same time, it can detect faults in the electrical equipment and cut off the faulty circuit in time to protect the electrical equipment and personal safety.

[0019] By adopting the above technical solution, the grounding component is used to ground the circuit to ensure the safety of maintenance personnel. Even if a sudden power outage occurs during maintenance, the electric energy can be introduced into the earth, forcing the switch to trip and avoiding the risk of electric shock. The system can also be artificially short-circuited to the ground to achieve the purpose of control and protection. Under abnormal conditions (such as short circuit), it can withstand current for a certain period of time, but under normal circumstances, it does not pass load current. It is mainly used in application scenarios such as circuit maintenance.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The sleeve and cover are convenient for arranging external circuits and making them easy to identify. The external circuits of the electrical switch cabinet are not easily entangled and damaged, and are also convenient for circuit maintenance.

The cover 22 is provided with a plurality of through holes 32 for the lines to pass through. The through holes 32 are connected to the sleeve 21. A plurality of slots 31 are provided on both sides of the adjacent through holes 32. The slots 31 are evenly arranged vertically. The wiring harness assembly 2 also includes at least one plug-in block 23, which is inserted into the slot 31. The cover 22 is evenly fixed with snap-in blocks 33 along the circumference of the edge.

The protrusions 34 are provided with snap-in grooves 35 for the snap-in blocks 33 to snap into. The cover 22 is snap-fitted to the sleeve 21.

[0035] Reference Figure 3 、 Figure 4 、 Figure 5 The protrusion 34 is slidably connected to a sliding block 41. The protrusion 34 is provided with a sliding groove 42 for the sliding block 41 to slide. The sliding block 41 slides along the length of the sliding groove 42, and the sliding groove 42 is connected to the clamping groove 35.

When one end of the sliding block 41 is located in the clamping groove 35 and the sliding block 41 continues to slide, the sliding block 41 abuts the clamping block 33 and drives the clamping block 33 out of the clamping groove 35.

[0036] Reference Figure 6 、 Figure 7A contact box 5 is fixed within the switch cabinet body 1. A grounding assembly 6 is provided within the switch cabinet body 1. The grounding assembly 6 includes a sensor 61, a static contact 62, and a spring 63. A support plate 71 is fixed to the inner side wall of the switch cabinet body 1.

[0037] The implementation principle of an electrical switch cabinet with easy-to-organize external circuits in the embodiment of the present application is as follows: when the electrical switch cabinet is installed and positioned and the external circuits need to be electrically connected to the electronic components in the switch cabinet, the external circuits pass through the sleeve 21 and are then organized by the cover body 22. The plug-in block 23 is used to better divide the external circuits, which can be divided according to the distance between the interconnected circuits in the switch cabinet body 1, so that the external circuits in the through-hole 32 can be routed more smoothly. After organization, the cover body 22 is clamped on the sleeve 21. If the external circuit fails and needs to be removed for maintenance, the sliding block 41 is pushed to slide, and the sliding block 41 abuts the clamping block 33, so that the clamping block 33 is disengaged from the clamping groove 35, completing the disassembly of the sleeve 21 and the cover body 22. The external circuits of the electrical switch cabinet are not easily entangled with each other, and are not easily damaged, and the circuit maintenance is convenient.
