Abstract
A ballast bobbin terminal includes a substantially flat and resilient terminal member having a forward portion for insertion into a bobbin pocket, and a rearward portion which will project rearwardly from the bobbin pocket. The forward portion of the terminal has a notch in each side edge thereof, and a tooth bent downwardly along each side edge forwardly of the notches, with the forward edge of the notch forming the leading edge of the projecting tooth. Each tooth projects downwardly and rearwardly such that the terminal may be inserted forwardly into a bobbin pocket, the leading edge of each tooth being biased against a wall of the pocket and gripping the pocket wall to prevent rearward movement of the terminal. A method of forming a tooth in a terminal includes the initial step of punching a notch in each side edge of the terminal such that a notch is formed with a forward edge parallel to the forward end of the terminal. Preferably, the notch is formed by punching downwardly through the upper face of the terminal. A tooth is then formed in each edge of the terminal edges forwardly of the notches, by deflecting a portion of the terminal downwardly to form a tooth having an lower leading edge formed of the forward edge of the notch.
