Single fastener electrical connector

An electrical connector for connecting a first conductor to a second conductor when secured by a fastener, comprising:

• a one-piece, generally U-shaped metal body having a first leg, a second leg and a bight portion joining said legs, each of said legs having an inner face, an outer face and a distal portion remote from said bight portion, said inner faces opposing one another and said distal portions spaced to receive the first conductor therebetween;
• a first opening in said first leg;
• a second opening in said second leg, said first and second openings being substantially aligned to permit a fastener to extend therethrough;
• at least one outer projection formed on said second leg extending outward from the outer face thereof for engaging the second conductor;
• a recess on the inner face of the distal portion of said first leg configured to cradle the first conductor;
• and
• at least one internal projection formed on the distal portion of said second leg and extending inward from the inner face thereof for engaging the first conductor,
• whereby, when a fastener extending through said openings is tightened with the second conductor abutting the outer face of said second leg and the first conductor in said recess, said at least one outer projection is forcibly pressed against the second conductor and the first conductor is clamped by said legs to forcibly press said at least one internal projection against the first conductor,
• wherein the distal portion of said first leg is outwardly convex, and said recess comprises the concave inside of said outwardly convex distal portion,
• wherein said recess comprises a knurled surface,
• wherein said at least one internal projection and said recess are substantially opposed, and
• wherein said at least one outer projection comprises a plurality of outer teeth, said at least one internal projection comprises a plurality of internal teeth, and each of said teeth has a distal edge adapted to embed itself in a respective conductor when the fastener is tightened.
