[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides an electrical cabinet line inlet structure, such as Figure 1-4 As shown, the electrical cabinet line inlet structure includes an electrical cabinet body 1, a plurality of line inlets 11 opened on one side of the electrical cabinet body 1, and a mounting structure 2 arranged on the electrical cabinet body 1; the mounting structure 2 includes a protective component 21 arranged on the line inlet 11, a clamping plate 22 arranged on the protective component 21, a clamping matching plate 23 arranged on the protective component 21 and matched with the clamping plate 22, a driving component 24 arranged on the protective component 21 for driving the clamping plate 22 to fix the wires, a partition 25 fixedly arranged in the electrical cabinet body 1, a sponge pad 26 symmetrically arranged at the opening position of the partition 25, and a limiting component 27 arranged on the partition 25 for fixing the sponge pad 26.

[0027] When in use, the protective component 21 is fixed at the position of the line inlet 11 on the electrical cabinet 1, and the sponge pad 26 is fixed on the partition 25 through the limit component 27. The wire is then passed through the protective component 21 into the accommodating cavity formed by the electrical cabinet 1 and the partition 25. The clamping plate 22, under the action of the driving component 24, cooperates with the clamping matching plate 23 to fix the wire at the line inlet 11, and then passes through the sponge pad 26 into the interior of the electrical cabinet 1 to prevent dust from entering the interior of the electrical cabinet 1 through the gaps.

[0028] Specifically, the protective assembly 21 includes a protective plate 211 which is arranged at the position of the wire inlet 11 and one end of which passes through the wire inlet 11, and a positioning block 212 which is screwed to the end of the protective plate 211 away from the electrical cabinet 1. The clamping plate 22 is slidably installed on the protective plate 211, and the clamping matching plate 23 is fixedly installed on the protective plate 211.

[0029] When installing the protective plate 211, align the protective plate 211 with the wire inlet 11 so that the protruding end of the protective plate 211 passes through the wire inlet 11, align the positioning block 212 with the end of the protective plate 211 passing through the wire inlet 11, and rotate the positioning block 212 so that the positioning block 212 and the protective plate 211 are screwed together to fix the protective plate 211 on the electrical cabinet 1.

[0030] More specifically, the driving assembly 24 includes a telescopic connecting rod 241 symmetrically hinged on both sides of the protective plate 211, a connecting plate 242 slidably arranged on the protective plate 211, and a compression spring 243 arranged at both ends of the connecting plate 242. The two ends of the telescopic connecting rod 241 are respectively hinged to the clamping plate 22 and the connecting plate 242, and the two ends of the compression spring 243 are respectively fixedly connected to the connecting plate 242 and the protective plate 211.

[0031] By passing the wire through the protective plate 211 and then squeezing the clamping plate 22, the connecting plate 242 is driven to slide on the protective plate 211 under the action of the compression spring 243, and drives the telescopic connecting rod 241 hinged at both ends to the clamping plate 22 and the connecting plate 242 to rotate around the hinge position with the protective plate 211, and drives the clamping plate 22 to slide and cooperate with the clamping matching plate 23 to fix the wire.

[0032] Among them, in order to prevent the insulation layer of the wire from being worn during long-term use, rubber pads 28 are fixedly arranged on the side where the clamping plate 22 and the clamping matching plate 23 are close to each other and at the line entry position of the protective plate 211; by arranging rubber pads 28 on the side where the clamping plate 22 and the clamping matching plate 23 are close to each other and at the line entry position of the protective plate 211, the insulation layer outside the wire can be prevented from being worn during long-term use.

[0033] In addition, in order to prevent the connection plate 242 from shifting when sliding, a slide groove 2111 is opened on the protective plate 211, and the connection plate 242 is slidably installed in the slide groove 2111; by sliding the connection plate 242 on the protective plate 211, the movement of the connection plate 242 is guided.

[0034] Furthermore, the limiting assembly 27 includes a limiting plate 271 symmetrically hinged on the partition 25 and a compression spring 272 arranged at one end of the limiting plate 271 away from each other, and both ends of the compression spring 272 are fixedly connected to the partition 25 and the limiting plate 271 respectively.

[0035] By pressing one end of the two limit plates 271 away from each other, the limit plates 271 are rotated around the hinged position with the partition 25, so as to facilitate placing the sponge pad 26 in a suitable position or taking it out. The limit plates 271 are loosened, and the limit plates 271 are rotated around the hinged position with the partition 25 under the action of the clamping spring 272 to reset the limit plates 271, so as to facilitate fixing the sponge pad 26 on the partition 25.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
