[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0022] Example 1, referring to Figure 1 and Figure 2 The first embodiment of the present invention provides a converter housing, which includes a mounting frame 100 and a closed frame 200.

[0023] The installation frame 100 includes four vertically distributed columns 101 and connecting columns 102 at both ends of the columns 101. A connecting column 102 is provided between every two adjacent columns 101. The four connecting columns 102 at one end of the columns 101 are arranged in a U-shape. The columns 101 and connecting columns 102 are spliced ​​together to form the installation frame 100, which can be disassembled for easy transportation. The multiple columns 101 and connecting columns 102 are of the same specifications, which also facilitates production and assembly. The columns 101 are of the same length, and the length of the connecting columns 102 is determined according to actual needs. The connecting columns 102 are divided into two groups, and the length of the connecting columns 102 in each group is the same.

[0024] The enclosed frame 200 includes cover plates 201 disposed at both ends of the uprights 101 and connected to the connecting columns 102. A door panel 202, a back panel 203, and a partition 204 are respectively disposed between three sets of adjacent pairs of uprights 101. The door panels 202 and the back panels 203 are distributed in parallel, and the partition 204 is located between the door panels 202 and the back panels 203. An open cavity M is formed between the cover plate 201, the door panels 202, the back panels 203, and the partition 204. When multiple converter housings with open cavity M are assembled, two adjacent converter housings can be connected through the open cavity M. That is, the opening of the previous converter housing is connected to the partition 204 of the next converter housing. This can save the redundant partition 204 and has the effect of reducing material consumption, processing time, and auxiliary material costs.

[0025] Example 2, refer to Figure 3 This is the second embodiment of the present invention, which differs from the first embodiment in that: the column 101 is formed by bending a flat plate multiple times, and includes a first flat plate 101a and a first vertical plate 101b arranged vertically, a second flat plate 101c perpendicular to the first vertical plate 101b and bending in the opposite direction to the first flat plate 101a, a second vertical plate 101d perpendicular to the second flat plate 101c and bending in the opposite direction to the first vertical plate 101b, and a third flat plate 101e perpendicular to the second vertical plate 101d and bending in the same direction as the second flat plate 101c, and after bending, it is connected to the third flat plate 101a. The fourth plate 101f is attached to the surface of 1e; the third vertical plate 101g is attached to the second vertical plate 101d after bending; the fifth plate 101h is attached to one side surface of the first plate 101a after bending; and the sixth plate 101i is attached to the other side surface of the first plate 101a after bending. An open cavity S1 is formed between the second plate 101c, the second vertical plate 101d, and the third plate 101e; and a closed cavity S2 is formed between the first vertical plate 101b, the second plate 101c, the third vertical plate 101g, and the fifth plate 101h, wherein the four sides of the closed cavity S2 are of equal length.

[0026] The column 101 is formed by bending a flat plate, which is easy to process and forms an open cavity S1 and a closed cavity S2, which can improve the three-dimensionality of the column 101 and increase its support strength.

[0027] Furthermore, the 101 bends of the column are all arc-shaped, with the vertical reversal bends being 1 / 4 arc-shaped and the turning reversal bends being 1 / 2 arc-shaped.

[0028] Multiple square grooves S2-1 and round holes S2-2 are equally spaced on the third vertical plate 101g and the fifth flat plate 101h that form a closed cavity S2. The square grooves S2-1 and round holes S2-2 are alternately distributed. Multiple grooves 101i-1 are equally spaced on the sixth flat plate 101i.

[0029] Furthermore, the connecting column 102 is formed by bending a flat plate multiple times. The cross-sectional shape of the connecting column 102 after bending is the same as that of the column 101, and the shapes of the connecting column 102 and the column 101 are consistent.

[0030] When the column 101 and the connecting column 102 are assembled together, the closed space is arranged and assembled inward. At this time, the square groove S2-1 and round hole S2-2 on the third vertical plate 101g and the fifth flat plate 101h can facilitate the installation of the bracket. After the bracket is installed, it will be located inside the converter box for flexible fixing of power facilities.

[0031] When multiple converter housings are spliced ​​together, the outer walls of the opening cavities S1 of two converter housings are joined together, increasing the distance between the internal parts of the two converter housings, which is beneficial for heat dissipation. At the same time, a W-shaped transition area is formed, which is beneficial for the staggered installation of the cover plate 201.

[0032] Furthermore, three equally spaced U-shaped grooves 101j are provided through the fourth plate 101f and the fifth plate 101h of the column 101.

[0033] The remaining structure is the same as that in Example 1.

[0034] Example 3, referring to Figure 4 and Figure 5 In the third embodiment of the present invention, a positioning element 103 is provided between the two ends of the column 101 and the two connecting columns 102. The positioning element 103 includes a cubic mounting block 103a, a cuboid and hollow positioning column 103b disposed on three adjacent surfaces of the mounting block 103a, and a cuboid positioning block 103c disposed on one of the remaining surfaces of the mounting block 103a.

[0035] Multiple perforations 103d are provided at equal intervals on the four sides of the positioning post 103b, and the end of the positioning block 103c is provided with a positioning hole 103e. The three positioning posts 103b are respectively inserted into the three closed cavities S2, and the positioning block 103c is inserted into the cover plate 201.

[0036] By inserting three positioning posts 103b into three closed spaces, each pair of adjacent connecting posts 102 and one upright post 101 can be spliced ​​and positioned together. By aligning multiple through holes 103d with multiple round holes S2-2 for multi-point fixation, the upright post 101 and connecting post 102 can be stably spliced ​​together to form a frame. At the same time, multiple positioning blocks 103c can also position and fix the cover plate 201, which facilitates the assembly and splicing of the converter housing.

[0037] Preferably, the end of the positioning post 103b is provided with a rounded chamfer to facilitate its insertion into the closed cavity S2, and the four sides of the positioning post 103b are simultaneously fitted with the four sides of the closed cavity S2 to improve stability.

[0038] Furthermore, a triangular plate 104 is provided at the included angle between each two adjacent third vertical plates 101g in the column 101 and the connecting column 102. The triangular plate 104 is provided with a central hole 104a. The stability between the column 101 and the connecting column 102 is further improved by the triangular plate 104. Preferably, the triangular plate 104 is not provided at the included angle between the two third vertical plates 101g used to install the door panel 202.

[0039] The remaining structure is the same as that in Example 2.

[0040] Example 4, refer to Figure 6 This is a fourth embodiment of the present invention, which provides a converter assembly cabinet, including a converter housing, and further including: a first cabinet 301, which is disposed on one side of the open cavity M and is consistent with the frame of the converter housing, and includes a sealing plate 302 installed at the opening of the open cavity M; a second cabinet 303, which is disposed on one side of the partition 204 and is consistent with the frame of the converter housing, wherein the partition 204 is replaced by the sealing plate 302; and wherein the first cabinet 301 and the second cabinet 303 are consistent with the frame of the converter housing, meaning that they are both frames formed by splicing together columns 101 and connecting columns 102. The difference between the two cabinets is that the length of the connecting column 102 is selected according to the actual size of the cabinet. The difference between the first cabinet 301 and the converter box is that the opening chamber M of the first cabinet 301 is equipped with a sealing plate 302. The difference between the second cabinet 303 and the converter box is that the partition 204 of the second cabinet 303 is replaced with a sealing plate 302. When the first cabinet 301, the converter box and the second cabinet 303 are spliced, each adjacent frame is connected through the opening cavity S1, which increases the distance between the internal parts of the two frames and forms a W-shaped transition area, which is conducive to the staggered installation of the cover plate 201.

[0041] The support frame 304 has an overall U-shaped structure and is fixed to the connecting column 102 at the bottom of the converter housing. It is used for support and to increase the bottom clearance. Raising the support frame 304 can increase the overall height of the converter cabinet. The U-shaped design makes the bottom of the cabinet empty, which is conducive to the ventilation and heat dissipation of the cabinet.

[0042] Furthermore, multiple converter enclosures are provided, arranged between the first cabinet 301 and the second cabinet 303. The number of converter enclosures can be flexibly arranged according to actual requirements to meet the requirements of more complex working environments.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
