The heat transfer of the capacitor to the heat transfer plate 205 is facilitated by the provision of a heat conducting plate 205, and the heat conducting plate 205 transfers the heat to the heat dissipation fins 206. By providing multiple heat dissipation fins 206, the heat dissipation can be well performed to meet people's needs; the protective cover 401 is inserted into the shell 1 of the capacitor, and the round head 407 is pressed against the inner wall of the shell 1 through the elastic force of the spring 406, so that the installation of the protective cover 401 is more stable. The protective cover 401 can protect the pin 3 of the capacitor. The provision of the protective net 404 facilitates the dissipation of heat. The provision of the through hole 402 facilitates the passage of external connecting lines. The structure is simple and easy to use.

[0025] Specifically, there are two supporting legs 202 , and the two supporting legs 202 are symmetrically arranged with the mid-perpendicular line of the base 201 as the symmetry axis.

[0026] Through the above technical solution, by providing two supporting legs 202, the base 201 can be well supported and the stability is enhanced.

[0027] Specifically, there are two mounting holes 203 , and the two mounting holes 203 are symmetrically arranged on the supporting foot 202 .

[0028] Through the above technical solution, the support foot 202 can be well fixed on other equipment, thereby facilitating the fixed installation of the capacitor and enhancing stability.

[0029] Specifically, there are multiple heat dissipation fins 206 , and the multiple heat dissipation fins 206 are arranged on the heat conducting plate 205 at equal distances.

[0030] Through the above technical solution, by providing a plurality of heat dissipation fins 206, heat can be dissipated well, the heat dissipation efficiency is enhanced, and the capacitor can work better during operation.

[0031] Specifically, the shape and size of the housing 1 match those of the protective cover 401 , and one end of the protective cover 401 extends into the housing 1 for connection.

[0032] Through the above technical solution, the connection effect between the housing 1 and the protective cover 401 is strengthened, which facilitates the installation of the protective cover 401.

[0034] Through the above technical solution, the connection effect between the fixing groove 403 and the protective net 404 is strengthened, which facilitates the fixing of the protective net 404 in the fixing groove 403.
