Abstract
The invention provides a retainer system for retaining a positive temperature coefficient resistor in a heater housing shaft having a shaft side wall. The retainer system includes a base, a spring, and shaft engagement means. The spring is formed in and spaced apart from the base. The spring extends radially outwardly from a longitudinal axis of the base and the spring has a neck that curves radially backwardly, spaced apart from the base and toward the longitudinal axis of the base. The spring also has a contact surface presented outwardly, away from the base. The shaft engagement means are for engaging the shaft side wall and securing the base within the shaft at a desired distance from the resistor. The retainer system can be secured within the shaft with the spring flexed to a desired extent and with the contact surface urged against the resistor to retain the resistor in the shaft.
