Lead connector with assembly frame and method of manufacture

A lead connector for an implantable medical device, the lead connector comprising:

• a first and a second ring-pin subassembly each comprising a conductive pin having a proximal end connected to a corresponding ring contact and having a distal end with a pin length defined between the proximal and distal ends;
• an assembly frame having a proximal and a distal end and comprising a plurality of openings and a plurality of steps;
• wherein a first of the plurality of openings is configured to receive the first ring-pin subassembly such that the conductive pin of the first ring-pin subassembly is inserted into and extends within the first of the plurality of openings such that the length of the conductive pin of the first ring-pin subassembly is contained inside the assembly frame from where it is attached to the corresponding ring contact at its proximal end to its distal end, except where it exits the assembly frame at the distal end, and wherein the corresponding ring contact of the first ring-pin subassembly engages a first of the plurality of steps;
• wherein a second of the plurality of openings is configured to receive the second ring-pin subassembly, such that the conductive pin of the second ring-pin subassembly is inserted into and extends within the second of the plurality of openings such that the length of the conductive pin of the second ring-pin subassembly is contained inside the assembly frame from where it is attached to the corresponding ring contact at its proximal end to its distal end, except where it exits the assembly frame at the distal end, and wherein the corresponding ring contact of the second ring-pin subassembly engages a second of the plurality of steps, and
• an insulating material that at least partially surrounds the corresponding ring contacts and fully surrounds the assembly frame.
