It should also be noted that the shell 10 has a first connecting portion and a second connecting portion, the first connecting portion, the second connecting portion 11 and the shell 10 are integrally formed, and the first connecting portion is located at one end of the shell 10, the second connecting portion 11 is located at the other end of the shell 10, the first opening 101 is located at the end of the first connecting portion, and the second opening 103 is located at the end of the second connecting portion 11. Those skilled in the art should understand that the above-mentioned first connection portion cooperates with the external dynamic cover plate, and the above-mentioned second connection portion 11 cooperates with the external static cover plate 100. In addition, the structures of the static cover plate 100 and the dynamic cover plate are consistent. Therefore, the utility model only shows the schematic diagram of the cooperation between the static cover plate 100 and the shell 10. It should also be noted that the connection method between the dynamic cover plate and the first connection portion is consistent with the connection method between the static cover plate 100 and the second connection portion 11, both of which are welding connections.

[0030] Further, the size of the first connection portion is consistent with the size of the second connection portion 11 , and the size of the second connection portion 11 is smaller than the cross-sectional size of the housing 10 .

[0031] It should also be noted that the housing assembly of the vacuum interrupter further includes a first connecting sleeve, which is arranged on the first connecting portion, and the housing assembly of the vacuum interrupter further includes a second connecting sleeve 20, which is arranged on the second connecting portion 11. It should also be noted that both the first connecting sleeve and the second connecting sleeve 20 are implemented as rubber sleeves, that is, the first connecting sleeve or the second connecting sleeve 20 is configured to prevent the housing 10 from falling during transportation, thereby preventing the first connecting portion or the second connecting portion 11 from being hit, scratched or deformed.

[0032] It should be noted that the second connecting sleeve 20 has four evenly distributed notches 201 on the side away from the housing 10, and both ends of the four notches 201 are connected to the outside. The structure of the first connecting sleeve is consistent with that of the second connecting sleeve 20, so it will not be described in detail.

[0033] Specifically, the housing assembly of the vacuum arc extinguishing chamber further includes two welding sleeves 30, and the two welding sleeves 30 are matched with the first connecting sleeve and the second connecting sleeve 20 respectively. It should be noted that each welding sleeve 30 has a connecting ring 31, four first connecting plates 32 and a fourth second connecting plate 33, the four first connecting plates 32 are evenly arranged and are welded to the outer wall of the connecting ring 31, and the four second connecting plates 33 correspond to the four first connecting plates 32 one by one, and the end of each second connecting plate 33 is connected to the end of the corresponding first connecting plate 32 away from the end. Specifically, the first connecting plate 32 and the second connecting plate 33 are integrally formed, and the first connecting plate 32 is perpendicular to the second connecting plate 33. Among them, the connecting ring 31 is matched with the end of the first connecting part or the second connecting part 11, and the end of the external static cover plate 100 or the end of the external moving cover plate is spaced a predetermined distance from the corresponding connecting ring 31.

[0034] Further, the end of the first connection part or the second connection part 11 has an annular installation groove 200, and the two connection rings 31 have an annular insertion end 311, and the two annular insertion ends 311 are respectively placed in the annular installation groove 200, and the size of the annular installation groove is larger than the size of the annular insertion end 311. It should be noted that when the annular insertion end 311 is placed in the annular installation groove 200, the distance between the connection ring 31 and the external static cover plate 100 or the external dynamic cover plate forms an annular welding groove 300, that is, the welding reliability of the external static cover plate 100 or the external dynamic cover plate and the first connection part or the second connection part 11 is improved by using a welding method with a quantitative solder.

[0035] Furthermore, the four first connecting plates 32 of the two welding sleeves 30 are also matched with the four notches 201 of the first connecting sleeve or the second connecting sleeve 20, and the four second connecting plates 33 of the two welding sleeves 30 are also matched with the outer wall of the first connecting sleeve or the second connecting sleeve 20, specifically, the connection between the second connecting plate 33 and the first connecting sleeve or the second connecting sleeve 20 can be implemented as an adhesive connection. It should also be noted that the depth of the notch 201 is greater than the thickness of the first connecting plate 32.

[0036] It should be noted that the advantage of the present invention is that the existing connection method between the movable cover plate or the static cover plate 100 and the shell 10 is welding in a vacuum brazing furnace, that is, solder is applied to the end of the movable cover plate or the static cover plate 100, and it is placed in a vacuum brazing furnace for welding. However, due to the structural design of the movable cover plate or the static cover plate 100, the contact surface between its end and the end of the shell 10 is small, so that the welding firmness of the movable cover plate or the static cover plate 100 and the shell 10 cannot be ensured. If the movable cover plate or the static cover plate 100 collides with external objects during the transportation of the finished product, it is very easy to cause cracks in the welding of the movable cover plate or the static cover plate 100, and thus the vacuum of the product cannot be guaranteed. The present invention effectively avoids this problem through quantitative welding.
