Electrically insulated threaded connection

An electrical insulated threaded connection comprising:

• a conductive box with a plurality of internal threads;
• a conductive pin with a plurality of external threads;
• a double-threaded electrical insulator sleeve disposed between the conductive pin and box,
• wherein the double-threaded electrical insulator sleeve comprises a plurality of external threads that mate with the plurality of internal threads of the conductive box and a plurality of internal threads that mate with the plurality of external threads of the conductive pin,
• wherein the plurality of external threads of the double-threaded electrical insulator sleeve starts to interfere with the plurality of internal threads of the conductive box before corresponding shoulders of the conductive pin and the conductive box make contact.

A double-threaded electrical insulator sleeve comprising:

• a plurality of external threads having a thread form that mates with a plurality of internal threads of a conductive box, and
• a plurality of internal threads having a thread form that mates with a plurality of external threads of a conductive pin,
• wherein the double-threaded electrical insulator sleeve disposed between the conductive pin and box, and
• wherein the double-threaded electrical insulator sleeve fills a full volume between the plurality of internal threads of the conductive box and the plurality of external threads of the conductive pin, and
• wherein there are no voids or pockets between any of the mating threads.
