Patent ID: 8911265

Claim:
An electrical connection plug for a multipolar lead of an active implantable medical device, the electrical connection plug comprising: an axial pin having a free end forming an axial electrical contact, a mounting rod adapted to connect with an inner central conductor, and a flange extending radially from the axial pin between the free end and the mounting rod; a retaining sleeve having a cylindrical bore through which the axial pin is inserted, a first end face of the retaining sleeve abutting the flange extending radially from the axial pin, and a second end face opposite the first end face; a locking ring inserted onto the axial pin and fixedly attached to the axial pin such that the locking ring abuts the second end face of the retaining sleeve; and wherein the retaining sleeve is secured axially between the radially extending flange and the locking ring, thereby preventing axial movement of the retaining sleeve relative to the axial pin while permitting rotation of the retaining sleeve relative to the axial pin; a plug body having a central bore housing the central conductor and the axial pin and carrying at its outer surface a plurality of annular electrical contacts; wherein the plug body houses a plurality of connection conductors, each connection conductor electrically connected with a different annular electrical contact; wherein the central conductor is coated with a lubricant to reduce rotational friction and facilitate rotation of the central conductor within the central bore.
