[0023] Explanation of reference numerals in the attached drawings: 1-plate, 2-mounting hole, 3-sealing groove, 4-seal, 5-box, 6-connector, 7-gasket. Detailed Implementation

[0024] like Figures 1-2 As shown, the high-pressure box sealing structure described in this application includes a plate 1;

[0025] The plate 1 is provided with a plurality of mounting holes 2, which are opened along the thickness direction of the plate 1 and are arranged along the circumference of the plate 1.

[0026] A sealing groove 3 is formed on one side of the plate 1, and the sealing groove 3 is formed on the side of the through hole away from the edge of the plate 1.

[0027] Specifically, the plate 1 has several mounting holes 2. It can be understood that the purpose of the mounting holes 2 is to make connections when the plate 1 is installed on the enclosure 5 of the high-voltage box. The specific location of the mounting holes 2 can be adapted according to the actual situation.

[0028] In one embodiment of this application, the sealing groove 3 is a flat-bottomed groove, that is, the bottom surface of the sealing groove 3 is a plane.

[0029] Furthermore, it also includes a sealing element 4, which is adapted to the sealing groove 3 and disposed within the sealing groove 3.

[0030] Furthermore, seal 4 is a sealing ring.

[0031] Specifically, such as Figure 3 As shown, the seal 4 is a sealing ring with an "O" shaped cross-section. After the plate 1, the seal 4, and the high-pressure box body 5 are pressed together, the seal 4 is embedded in the sealing groove 3 of the plate 1. The sealing groove 3 restricts the degree of freedom of movement of the seal 4, thereby preventing misalignment due to overpressure. In one embodiment of this application, the sealing ring is made of EPDM rubber.

[0032] Furthermore, the sealing element 4 is a sealing strip.

[0033] Specifically, the sealing element 4 is a sealing strip with a rectangular or square cross-section. After the plate 1, the sealing element 4, and the high-pressure box body 5 are pressed together, the sealing element 4 is embedded in the sealing groove 3 of the plate 1. Because the sealing element 4 has a rectangular or square cross-section, the contact surface between the sealing element 4 and the sealing groove 3 is large, resulting in greater friction, thus preventing misalignment due to overpressure. In one embodiment of this application, the sealing strip is silicone foam.

[0034] Furthermore, an excessively thick plate 1 would affect the overall weight of the high-voltage box, impacting subsequent transportation, while an excessively thin plate 1 would cause damage or deformation during production or transportation. To avoid affecting the subsequent transportation of the high-voltage box and preventing damage or deformation of plate 1 during production or transportation, the thickness of plate 1 needs to be moderate. Preferably, the thickness of plate 1 needs to be moderate, ranging from 10 to 13 mm.

[0035] Furthermore, in one embodiment of this application, the thickness of plate 1 is 11 mm.

[0036] like Figures 3-4As shown, this application also provides a high-pressure box, including a box body 5, a connector 6, and a high-pressure box sealing structure as described above. The top of the box body 5 has an opening, the plate 1 is adapted to the top of the box body 5, and the connector 6 is adapted to the mounting hole 2. The box body 5 and the sealing structure are connected by the connector 6.

[0037] In one embodiment of this application, the connector 6 can be a conventional bolt, which passes through the mounting hole 2 and abuts against the housing 5, thereby connecting the housing 5 and the high-pressure box sealing structure.

[0038] Furthermore, in order to protect the plate 1 and the connector 6 and prevent the connector 6 from compressing the plate 1 for a long time and causing the plate 1 to deform, the high-pressure box described in this application also includes a gasket 7. The gasket 7 is disposed between the plate 1 and the sealing member 4, and the gasket 7 has a through hole in the middle that matches the mounting hole 2.

[0039] It is understood that the washer 7 is designed to prevent direct contact between the connector 6 and the plate 1, thereby preventing the connector 6 from pressing against the plate 1 for a long time. In one embodiment of this application, the material of the washer 7 can be soft silicone, soft rubber, a spring washer 7, or a flat washer 7. Those skilled in the art can make the selection according to the actual situation.

[0040] It is understood that the number of washers 7 can be selected by those skilled in the art based on the actual situation. For example, in one embodiment of this application, one spring washer 7 and one flat washer 7 can be selected.

[0041] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application.

[0042] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this application.
