An electrical connector assembly for coupling a first implantable device to a second implantable device, said assembly comprising a male element having one or more male contacts electrically coupled with the first implantable device and a female element comprised of a socket having one or more correspondent female contact electrically coupled with said second implantable device and adapted for receiving said one or more male contact. One or more male contacts are sealed to the male element through a glass or ceramic sealing material. A female contact of said socket comprises a contact structure comprised of a plurality of conductive elongated wires which extend along the internal surface of said the female contact in a hyperboloid arrangement, thereby providing an electrical coupling between the female contact and the corresponding male contact in a plurality of points.
