Abstract:
1. An implantable medical connector stack having easy to install ring grooves for receiving contact springs comprising: a first seal element made of a dielectric material comprising an annulus comprising a projection; said annulus comprising a generally planar wall surface; a conductive ring contact element comprising an interior wall surface adjacent at least one axial opening; a second seal element made of a dielectric material comprising an annulus comprising a projection; a canted coil spring; wherein the conductive ring contact element is engaged to the first seal element and the second seal element and a ring groove is formed by a bottom wall of the conductive ring contact element and two side walls formed from one each of the first and second seal elements; and wherein the generally planar wall surface of the first seal element forms a dielectric side wall of the ring groove that together with the interior wall surface of the conductive ring contact element define a physical stop for retaining the canted coil spring inside the ring groove, and a portion of at least one of the seal elements projects into the conductive ring contact element.
