Abstract
A first mold die and a second mold die are moved together and are shaped to define a mold cavity therebetween. A capacitor pellet is positioned within the mold cavity and a plurality of projections extend inwardly to engage the capacitor pellet and hold it spaced away from the cavity side wall. The method comprises placing the pellet body within the cavity molding and retentively engaging the pellet body with a plurality of projections to provide a space between the pellet body and the cavity side wall. A molding material is used to fill the space to provide a coating on the pellet body.
Claims6
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 the 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 to harden;
- molding a protective material to form a protective coating around said capacitor pellet and said tear drop shaped 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.
