The utility model provides a
capacitor sealing structure and a
capacitor, and relates to the field of capacitors, and the
capacitor sealing structure comprises a capacitor housing, a buffer layer, a cooling fin, a bolt seat and a sealing
assembly. The radiating fins are arranged between the inner wall of the capacitor shell and the outer wall of the buffer layer, so that the radiating efficiency of the capacitor is improved, and the service life is prolonged; a buffer cavity is arranged in the buffer layer, so that the damping effect is further enhanced, and internal elements of the capacitor are protected from being damaged by
impact. The sealing
assembly comprises a sealing base, a connecting plate and a locking support, and the sealing performance and the
structural stability are enhanced through a multi-layer structure. The sealing structure is convenient to
mount and high in adaptability, the assembling and disassembling processes are simplified through the movable
connection design, and the sealing structure is suitable for scenes needing frequent maintenance. And the capacitor core is connected with the shell through the sealing
assembly, so that the capacitor has excellent heat dissipation performance, sealing performance and
impact resistance, and the overall performance and reliability of the capacitor are improved.
