Electrical connector

An electrical connector comprising:

• (A) a plug comprising a substantially hollow and substantially cylindrical body portion comprising:
• an interior portion having a plurality of electrical contacts;
• and
• an annular recess on an exterior of the body portion;
• (B) a receptacle comprising:
• a plurality of annular electrical contacts that contact the plurality of electrical contacts when the plug is mated to the receptacle, wherein the plug can be rotated within the receptacle while maintaining electrical contact between the plurality of annular electrical contacts on the receptacle and the plurality of electrical contacts on the plug, wherein the plurality of annular electrical contacts have a first diameter and are separated by a plurality of individual and separate annular insulators having a second diameter smaller than the first diameter;
• and
• at least one retention arm that engages the annular recess on the plug when the plug is properly mated with the receptacle to maintain the plug properly mated with the receptacle.
