ABSTRACT:
An end cap for a defrost heater is shown in which a positive locking mechanism is used to allow the lead wires to extend downward from the end cap. This increases the end cap's resistance to moisture and simplifies the design, thus lowering manufacturing cost. The end cap is also shown with a vertical vent that overlaps the retaining bore to significantly increase venting area over prior designs. The positive locking mating tab and the vent are located in two separate, but adjacent, vertical passages.
