Abstract
A capacitor assembly and method of manufacture is disclosed, the capacitor being of the type including a capacitor winding received into a capacitor housing cavity, with a pair of terminal contact straps each positioned in contact with an opposite face of the capacitor winding and along the upper surface of the housing adjacent the cavity. A cap overlying the capacitor winding, as well as the terminal, is provided by an injection molding of material by means including a molding die which compresses one of the contact straps which normally upwardly extend to enable positioning of the mold top plates over the housing recess during the molding process. Spring back of the contact allows the contact to return to its original position.
Claims3
A method of manufacturing a molded capacitor of the type including a molded capacitor housing having a recess extending into a flanged side thereof and a capacitor winding disposed therein, a pair of connector straps having sections positioned in contact with a respective end face of said capacitor winding, at least one of said connector straps including a spring tab section extending from the said flanged side at an acute inclination thereof, said method comprising:
- assembling said connector straps and capacitor winding into said capacitor housing;
- molding a top cover in place over said flanged side and capacitor winding in said recess, said molding step including the steps of placing said assembled components into a molding die, said die including a top plate positioned over the assembled components and adapted for defining in part a die cavity corresponding to said top cover, said top plate further including a surface pressing said spring tab against said flanged side with said top plate in position, said molding step including the step of placing said top plate in position compressing said spring tab and injecting a plastic molding material into said cavity.
