Abstract
A female plug body for an electric cord set with at least two contact openings, one opening smaller than the other, has an insert made of a more rigid insulating material than the plug body, disposed within the plug body. The insert has a pair of cavities providing clearance for one side of each of a pair of contacts embedded within the plug body, so that the resistance to insertion of a male plug is not affected by the ambient temperature. The insert also provides a channel providing rigid support for the opening in the plug for the 'hot' contact of the female plug which resists insertion of an oversized plug blade into the 'hot' contact.
