Patent ID: 7798836

Claim:
An electric plug connector assembly comprising: (a) a first plug connector comprising a first hermaphrodite electric contact element having first and second legs, each of the first and second legs having a respective first plug connector inner surface; (b) a second plug connector comprising a second hermaphrodite electric contact element having third and fourth legs, each of the third and fourth legs having a respective second plug connector inner surface; wherein the first hermaphrodite electric contact element is identical to the second hermaphrodite electric contact element; wherein the first hermaphrodite electric contact element opens toward the second hermaphrodite electric contact element like a fork; wherein the first plug connector inner surfaces embrace at least in part one of the third and fourth legs; wherein each of the first and third legs comprises a respective projection of convex shape and each of the second and fourth legs comprises a respective concave recess; and wherein the shape of each concave recess is adapted to each convex projection so that in an engaged condition of the first and second plug connectors the convex projection of the first leg is in positive contact, at least in part, with the concave recess of the fourth leg or the convex projection of the third leg is in positive contact, at least in part, with the concave recess of the second leg; wherein each of the second and fourth legs has a flat surface on a side of the second and fourth legs, respectively, opposite the concave recess; and wherein each of the second and fourth legs has a width such that the flat surfaces of the second and fourth legs rest against each other in the engaged condition, establishing electric contact in this way.
