[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 and Figure 4 , which shows a terminal installation box for a power module provided by an embodiment of the present utility model. The box includes a box body 100 with a side opening 110. The box body 100 includes an upper cover plate 200 and a lower cover plate 300. The upper cover plate 200 includes an outer plate 210, a bending part 220, and a guide groove plate 230 connected in sequence. The bending part 220 is arranged at the side opening 110 of the box body 100. The guide groove plate 230 is formed by bending inward along the bending part 220 into the interior of the box body 100. The guide groove plate 230 is provided with a plurality of equally spaced and parallel guide through grooves 231. The guide through grooves 231 are adapted to the guide convex parts on the power module (not shown in the figure). The guide through grooves 231 extend from the bending part 220 into the interior of the box body 100, and the guide through grooves 231 penetrate through the upper and lower surfaces of the guide groove plate 230. The guide through grooves 231 are used for guiding and limiting the power module when it is inserted. The guide groove plate 230 and the outer plate 210 are integrally formed by sheet metal, eliminating the need to add additional sheet metal parts for assembling the guide through grooves 231, thus reducing the number of parts, improving the assembly efficiency and accuracy of the product, reducing the assembly difficulty and production cost, and at the same time improving the reliability of the product. The guide through grooves 231 are adapted to the guide convex parts on the power module, realizing the guiding and limiting functions when the power module is inserted, avoiding problems such as possible deviations and inaccurate alignment during the insertion process, and improving the efficiency of installing the power module.

[0024] Furthermore, the guide groove plate 230 is parallel to the outer plate 210, ensuring uniform force on the power module during the installation process and reducing the risk of damage to the power module caused by improper installation.

[0025] Furthermore, a support plate 232 is provided at one end of the guide groove plate 230 away from the side opening 110. The support plate 232 is in contact connection with the outer plate 210. The support plate 232 is formed by bending and sheet metal working at one end of the guide groove plate 230 away from the side opening 110, and it is used to support the guide groove plate 230 to prevent the guide groove plate 230 from deforming after the power module is inserted and removed multiple times.

[0026] Further, the support plate 232 is provided with a first mounting hole 233, and the outer plate 210 is provided with a second mounting hole 234 corresponding to the first mounting hole 233. In this embodiment, the first mounting hole 233 is a threaded hole. By sequentially passing a bolt through the second mounting hole 234 and the first mounting hole 233, the support plate 232 is fixed to the inner side of the outer plate 210, and further the guide groove plate 230 is fixed to avoid the shaking of the guide groove plate 230.

[0027] Further, a plurality of support blocks 400 are provided between the upper cover plate 200 and the lower cover plate 300. The support blocks 400 are provided with third mounting holes 410 on both the upper and lower surfaces, and the outer plate 210 and the lower cover plate 300 are both provided with fourth mounting holes 235 corresponding to the third mounting holes 410. In this embodiment, the third mounting hole 410 is a threaded hole, and the fourth mounting hole 235 is a through hole. By sequentially passing a bolt through the through holes of the outer plate 210 and the lower cover plate 300 and screwing it into the threaded hole on the support block 400, the support block 400 is fixed between the outer plate 210 and the lower cover plate 300, so that the overall structure of the box body 100 is not easily deformed and more stable.

[0028] Further, a plurality of guide groove plates 230 are arranged at intervals, and a support block 400 is provided between two adjacent guide groove plates 230.

[0029] Further, the lower cover plate 300 is provided with a snap hole 310. The snap hole 310 is arranged at a position close to the side opening 110 of the lower cover plate 300 and is adapted to the snap member on the power terminal. After the power terminal is pushed into the box body 100 along the guiding through groove 231, the snap member is embedded into the snap hole 310, thereby fixing the power module, further ensuring the stability of the power module, and preventing the power module from slipping out and falling off the box body 100 due to vibration or other reasons.

[0030] Further, the upper cover plate 200 further includes upper side plates 240 arranged on both sides of the outer plate 210. The upper side plates 240 on both sides are bent inward by 90° for connecting and fixing with the side box plates of the box body 100, or directly connecting and fixing with the lower cover plate 300 of the box body 100 to form the aforementioned side opening 110.

[0031] Further, the guide groove plate 230 is arranged on one side inside the box body 100, and a space for installing other devices is reserved on the other side inside the box body 100.

[0032] Further, the bending portion 220 is U-shaped, and the guiding through groove 231 extends from one end of the guide groove plate 230 close to the side opening 110 along the bending portion 220 to the outer plate 210.

[0033] For the above-mentioned terminal installation box of the power module, the guide groove plate and the outer plate are integrally formed by sheet metal stamping. No additional sheet metal parts are required for assembly to form the guiding through groove, thereby reducing the number of components, lowering the production cost, improving the assembly efficiency and accuracy of the product, reducing the assembly difficulty and production cost, and at the same time enhancing the reliability of the product. The guiding through groove is adapted to the guiding convex part on the power module to achieve the guiding and limiting functions during the insertion of the power module, avoiding problems such as possible deviation and inaccurate alignment during the insertion process, making the installation and replacement processes of the power module more simple and rapid, and improving the installation efficiency.

[0034] It should be noted that the present utility model is not limited to the above-mentioned embodiments. According to the creative spirit of the present utility model, those skilled in the art can also make other changes. All these changes made based on the creative spirit of the present utility model should be included within the scope of protection required by the present utility model.
