High-safety composite material square capacitor shell

The utility model belongs to the technical field of structural design of electronic components, and particularly relates to a high-safety square capacitor shell made of a composite material. Comprising a main shell, a shell cover, conductive pins and a ventilation cap, the main shell is a square box body with an opening in the upper end, and the shell cover is embedded in the opening in the upper end of the main shell; the shell cover is of a rectangular flat plate structure, thickened installation areas are arranged on the two sides of the upper end face of the shell cover, and through holes are formed in the middle of the installation areas. An air hole is formed in the middle of the shell cover; the conductive pin is of a U-shaped structure, and the two vertical edges of the conductive pin extend upwards from the upper end face of the extending shell cover to form an external terminal. And the ventilation caps are embedded in the ventilation holes. The high-safety composite material square capacitor shell
