[0032] The utility model makes a fixed plate formed by integrally stamping sheet metal into a split fixed plate, and provides an upward supporting force for the fixed plate by connecting a support platform arranged at the lower end edge of the installation opening and facing the inner side of the outdoor unit casing with the lower end of the fixed plate, and then provides a horizontal fastening force for the fixed plate by connecting an electric control box back plate arranged on the inner side of the outdoor unit casing with the side of the fixed plate, thereby finally realizing a stable and detachable installation of the fixed plate, and the wiring terminal seat and the wire pressing plate are installed on the outer surface of the fixed plate, which not only solves the defects of the traditional electric control wiring terminal fixing structure, but also greatly improves the operating safety and maintenance efficiency of the air-conditioning system, and is a major technological advancement in the field of air-conditioning manufacturing.

[0033] Furthermore, the fixing plate 5 includes an upper fixing plate 51, a middle fixing plate 52 and a lower fixing plate 53, the upper fixing plate 51 is horizontally arranged at the upper edge of the installation port 11, the side of the upper fixing plate 51 is detachably connected to the back plate 2 of the electric control box, the side of the upper fixing plate 51 away from the installation port 11 is vertically connected to the middle fixing plate 52, the side of the middle fixing plate 52 is detachably connected to the back plate 2 of the electric control box, the end of the middle fixing plate 52 away from the upper fixing plate 51 is connected to the lower fixing plate 53, the lower surface of the lower fixing plate 53 is tightly attached to the upper surface of the support platform 12 and is detachably connected, the outer surface of the middle fixing plate 52 is provided with a terminal block 3, and the upper surface of the lower fixing plate 53 is provided with a wire pressing plate 4.

[0034] like Figure 2 As shown, the original electric control terminal fixing plate is replaced by a new split design instead of sheet metal processing. Different from the previous integrated sheet metal parts, the fixing plate 5 is an independent structural part, and the upper and lower ends are separated from the side panels of the air-conditioning outdoor unit. It is a detachable structural part, which improves the processing and assembly efficiency of the sheet metal, has a good fixing effect, and high disassembly and assembly efficiency. It reduces the difficulty of construction, reduces production costs, and improves efficiency. At the same time, the upper fixing plate 51, the middle fixing plate 52 and the lower fixing plate 53 are connected in pairs at different angles, and each has different functions.

[0043] Furthermore, a clamping hole is provided on one side of the inner surface of the middle fixing plate 52 close to the electric control box back plate 2, and a clamping block is provided at a corresponding position on the outer surface of the second fixing plate 22, and the clamping block matches the clamping hole.

[0044] A plurality of clamping blocks are matched and fitted into the clamping holes, and fixing bolts are passed through the middle fixing plate 52 and the second fixing plate 22 for screwing and fixing. This method makes the structure more stable.

[0045] Furthermore, it includes reinforcing ribs. The support platform 12 is arranged obliquely at the lower end edge of the installation opening 11. The angle between the upper surface of the support platform 12 and the plane where the installation opening 11 is located is 10°-30°. A reinforcing rib is provided on the side of the connection between the support platform 12 and the lower fixed plate 53 close to the installation opening 11.

[0046] The inclined design of the support platform 12 and the application of reinforcing ribs improve the rigidity of the entire fixed structure, and can maintain good structural integrity even in harsh environments, thereby extending the service life of the equipment.

[0047] Furthermore, the length of the middle fixing plate 52 in the horizontal direction is longer than that of the upper fixing plate 51 and the lower fixing plate 53 .

[0048] The middle fixing plate 52 is designed to be longer in horizontal direction than the upper fixing plate 51 and the lower fixing plate 53 , so that avoidance space is reserved above and below the fixing plate 5 , which can provide more heat dissipation space and further improve the heat dissipation efficiency.

[0049] Furthermore, the middle fixing plate 52 is provided with at least three reserved holes.

[0050] When workers are assembling external units, in order to prevent related cables or electronic control components of a certain size, such as magnetic rings or coils, from falling loose, or there is a need to bundle the cables, the cables or electronic control components are bundled and integrated, and then inserted into one of the reserved holes with a barb tie to fix them. At the same time, multiple reserved holes allow workers to freely choose a suitable hole position to fix the related electronic control components with a barb tie, which is more convenient.
