ALUMINUM NONSOLID ELECTROLYTIC CAPACITOR

PROBLEM TO BE SOLVED: To prolong the service life by bending a lead wire in U-shape or V-shape at the lower end in an elastic sealing body and further bending reversely in U-shape or V-shape at the upper end and enhancing the airtightness at the sealed part by repeating the operation thereby suppressing permeation of gasified electrolyte. SOLUTION: Electrolyte or gasified electrolyte intruded through a minute gas between the insertion hole 4 of an elastic sealing body 3 and a lead wire 5 is stopped at the lower end of the U-shaped part 6 of the lead wire 5 and prevented from being leaked to the outside. Even if it is not stopped at the lower end of the U-shaped part 6, the intruded electrolyte or gasified electrolyte is passed through a reverse U-shaped part 7 and directed to the outside. More specifically, the passage is lengthened in order to reduce or prevent leakage to the outside. Formation of the U-shaped part 6 and the reverse U-shaped part 7 may be repeated two times or more. According to the structure, leakage of electrolyte to the outside can be suppressed or prevented.
