Abstract
An electrical terminal and a system of the terminal and a housing is disclosed as an example of the present invention. The electrical terminal and the housing have a number of advantages including being sufficiently stiff to prevent arcing and physical damage to the electrical terminal upon being exposed to surge current/voltage. The terminal includes a contact with a base portion from which two spaced apart arms extend outwardly. First portions of the arms are generally parallel to one another. Second portions of the arms converge toward each other and then flare outwardly along third portions of the arms. At the junction of the second and third portions, there is a contact region formed to receive the lead of a surge protection device. The terminal is enclosed in an opening in the electrically insulative housing, the opening being bordered by walls closely adjacent to the first portions of the arms. The spacing of the walls from the arms is about 0.001 inches on each side of the terminal. When the terminal is exposed to a surge current/voltage, the walls stiffen the terminal and prevent arcing and physical damage.
