[0026] As Figure 2As shown in the figure, the installation part 11 includes two installation plates 111. The two installation plates 111 are flat plates, and the two installation plates 111 are symmetrically arranged at intervals. The connecting part 12 is located between the two installation plates 111. The connecting part 12 includes a wall plate 121 and two side plates 122. The wall plate 121 is parallel to the two installation plates 111. The two side plates 122 are perpendicular to the wall plate 121. The two side plates 122 are respectively connected to both sides of the wall plate 121 and are respectively connected to the two installation plates 111. A threaded hole 123 is provided at the center position of the wall plate 121 for bolt connection with the wire nose 20. The first stopping part 13 includes a clamping groove 131.

[0030] Please refer toFigure 5 This is a schematic diagram of the high-voltage control box provided by an embodiment of the present utility model. The high-voltage control box includes the anti-rotation wire nose assembly described in any of the above embodiments. When the high-voltage control box needs to connect a cable, the cable is first connected to the wire nose 20, and the mounting seat 10 is connected to the conductive component of the high-voltage control box. Then, the second stop portion 23 of the wire nose 20 is engaged and clamped with the first stop portion 13 of the mounting seat 10, and the wiring hole 221 and the threaded hole 123 are coaxially aligned and connected with bolts. During the process of screwing the bolts, the second stop portion 23 is restricted by the first stop portion 13 and cannot rotate, so that the wire nose 20 will not rotate around the bolt as the axis, and the installation is convenient. Taking the example that the electronic devices in the high-voltage control box need to be grounded, the box body of the high-voltage control line is made of sheet metal, and the electronic devices use the sheet metal body inside the box as the conductive component. The grounding wire of the electronic devices is connected and conducted with the internal sheet metal body. The mounting seat 10 in the anti-rotation wire nose assembly is also made of sheet metal, and the mounting seat 10 is welded to the outside of the box body. The grounding cable is connected to the wire nose 20, and the grounding of the electronic devices is achieved after the wire nose 20 is connected to the mounting seat 10.

[0031] In some other embodiments, the conductive component of the industrial equipment is a copper busbar. At this time, the mounting seat in the anti-rotation wire nose assembly is also made of copper plate material, and the mounting seat is bolted to the copper busbar of the industrial equipment. The conductive cable is connected and conducted with the copper busbar through the wire nose and the mounting seat. According to different conductive components, the mounting seat can be made of corresponding materials.

[0032] In other ways, when multiple wire noses need to be installed, after the installation is completed, the bolts need to be loosened for angle adjustment to make the installation directions of the multiple wire noses consistent for aesthetics. However, for the anti-rotation wire nose assembly provided by the present utility model, as long as the installation directions of the mounting seats are consistent, when each wire nose is installed, after the first stop portion and the second stop portion are matched, the installation directions of each wire nose will be consistent, and there is no need for manual adjustment, which saves time and effort.

[0033] Although the above embodiments are separately described and elaborated, for some common technologies, in the view of those of ordinary skill in the art, replacements and integrations can be made between the embodiments. For the content not clearly recorded in one of the embodiments, reference can be made to the other embodiment with records.

[0034] The above-described embodiments do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the above embodiments shall be included in the protection scope of the technical solution.
