[0018] The screw cap 81 is threadedly connected to the module box 2, so as to facilitate the replacement of the desiccant 83 at a later time.

[0019] Reference Figure 1 and Figure 2 Screws 9 are also connected between the epoxy cover plate 6 and the module box 2. The epoxy cover plate 6 and the module box 2 are sealed and fixed by glue, and the through hole 61 and the metal external electrode 3 are also sealed by glue.

[0020] During the manufacturing process, the epoxy cover plate 6 and the metal outer electrode 3 are first fixed to the module box 2 by screws 9 to pre-fix the integrated module. Finally, the gap between the epoxy cover plate 6 and the module box 2 is filled and fixed by glue, and the same is true between the through hole 61 and the metal outer electrode 3, so that the integrated module can be fully sealed to prevent dust and water vapor from entering the module box 2.
