In some embodiments, the bottom surface of the base 10 is provided with a compression molded symbol (not shown in the drawings); wherein a positive sign is provided adjacent to the first receptacle 210, a negative sign is provided adjacent to the second receptacle 220, and the compression molded sign corresponds to the positive sign on the capacitor. Thus, the positive electrode and the negative electrode are conveniently distinguished, and corresponding assembly is carried out.
