The back of the electrical appliance mounting plate 10 is provided with the stop mechanism 20, when the electrical appliance mounting plate 10 is opened by 90 degrees, after the spring plugging positioning pin 231 is pulled up, the limiting plate can rotate by the connecting shaft 211, the pin hole 232 for inserting the positioning pin 231 is arranged at the position rotating by 90 degrees, the spring plugging positioning pin 231 is put down, the rotation of the limiting part 22 can be limited, and the limiting part 22 is matched with the outer wall (the upper edge part of the shell 30 is a metal plate) to limit the rotation of the electrical appliance mounting plate 10. The limiting member 22 is provided with an L-shaped folded edge and a dead edge at the folded edge, so that stress during grinding and rotation of the limited metal plate can be prevented. The front and back sides of the electric appliance mounting plate 10 are provided with the assembly control plates 102, the electric appliance mounting plate 10 is fully utilized, wiring among the control plates 102 is shortened, and space is saved. A square hole is dug in the middle of the electric appliance mounting plate 10, and the driving wire penetrates through the middle of the electric appliance mounting plate 10, so that the driving wire is shortened, the interference of other devices on the driving wire is reduced, and the reliability is improved. The dead limit of square hole inward book all around prevents to grind the line.

To sum up, the utility model provides a converter has realized rotating between electrical apparatus mounting panel 10 and the casing 30 and is connected through being provided with rotation connection structure 40, through setting up backstop mechanism 20, rotates the back at electrical apparatus mounting panel 10 for casing 30, can fix on relative position, prevents to take place to rock or even rotate at the spare part in-process that overhauls or inspect electrical apparatus mounting panel 10 the back to the use reliability of product has been improved.
