Abstract
The utility model discloses an external structure of a direct current filter capacitor. The external structure comprises a cylindrical shell. An end cover is arranged at the upper end of the cylindrical shell. Guide pillars are arranged on the end cover. The bottom diameters of the guide pillars are greater than the diameters of the upper parts of the guide pillars. The guide pillars are fixedly connected with the end cover through threads. A pair of symmetrical fixing legs is arranged at the lower end of the cylindrical shell. Mounting holes are formed in the fixing legs. The external structure of the direct current filter capacitor is simple, rational, compact and convenient to mount and manufacture.
