Abstract:
A method for making a capacitor comprising:forming a capacitor pellet having a pellet anode end, a pellet cathode end, a pellet front wall, a pellet rear wall, first and second opposite pellet side walls, and a longitudinal axis extending between said pellet anode and cathode ends; connecting an anode wire to said anode end of said pellet with said anode wire extending from said anode end of said pellet; applying a fluid conductive material capable of hardening to said cathode end and to lower portions of said pellet front wall, rear wall, first side wall, and second side wall adjacent said cathode end of said pellet to create a tear drop shaped conductive body having a tear drop point extending axially away from said cathode end of said pellet; permitting said fluid conductive material of said tear drop shaped conductive body to harden; placing said pellet having said conductive body thereon within a mold cavity having a plurality of walls provided with a plurality of projections extending inwardly therefrom into said mold cavity; engaging only said tear drop shaped conductive body with said plurality of projections so as to center said pellet within said cavity and create a substantially uniform space within said cavity around said front wall, said rear wall, and said first and second side walls of said pellet; introducing a molding material into said space within said cavity to form a protective coating of substantially uniform thickness around said pellet, and to substantially surround said tear drop shaped conductive body except where said projections engage said conductive body; removing a portion of said tear drop point and said protective coating to form an exposed cathode termination surface from said conductive body.
