Supercapacitors 2 are inserted into each of the independent cavities. The bottom surface of each independent cavity has an annular protrusion 9 that closely adheres to the bottom of the supercapacitor 2, forming an outer annular sealed space 11 and an inner sealed space 8. The outer surface of the housing 1, facing away from the opening, has explosion-proof grooves 6 that correspond one-to-one with the inner sealed spaces 8. In this embodiment, the explosion-proof grooves 6 are X-shaped with an expanded-diameter circle at their center.

[0022] The shell 1 has a filling and sealing cavity 10 on its open side, which communicates with each independent cavity. The bottom plate of the filling and sealing cavity 10 has reinforcing ribs 4 connected to the partitions 12. Each partition 12 is connected to two reinforcing ribs 4, which are distributed in a Y-shape. The lead 3 of the supercapacitor 2 passes through the filling and sealing cavity 10 to reach the open side of the shell 1. The filling and sealing cavity 10 is filled with resin glue, which is not shown in the figure.

The top surface of the opening side of the housing 1 is provided with positive and negative identification numbers 7 corresponding to the Ω-shaped positioning holes 13, so as to facilitate circuit connection.

[0024] The bottom of the housing 1 is symmetrically provided with two elastic buckles 5 for easy installation.

[0025] During assembly, first insert the four supercapacitors 2 into their respective independent cavities in parallel, and then position and wrap the supercapacitors 2 so that their bottoms are tightly attached to the corresponding annular protrusions 9. At the same time, install the positive and negative leads of each supercapacitor 2 according to the corresponding positive and negative identification numbers 7, and insert the leads 3 into the Ω-shaped positioning holes 13. Then, fill the filling and sealing cavity 10 with resin glue. After the resin glue is flush with the edge of the opening side of the shell 1, let it stand and cure.
