Power connector set with secondary lock

A power connector, comprising:

• (a) first and second connector portions for connection to respective power conductors;
• (b) a bayonet locking mechanism for locking said connector portions upon rotation of said first and second connector portions in a first direction relative to each other and unlocking said connector portions upon rotation of said first and second connector portions in an opposite direction relative to each other;
• and
• (c) a secondary locking mechanism for preventing rotation of said first and second connector portions in said opposite direction relative to each other, thereby preventing accidental disconnection of said first and second connector portions, said secondary locking mechanism being comprised of a slot disposed in said first connector portion, a pin disposed in said second connector portion, and a spring connected to said pin for urging said pin into said slot when said first and second connector portions are locked via said bayonet locking mechanism, said secondary locking mechanism requiring the insertion of a tool into said slot for retraction of said pin out of said slot to permit rotation of said first and said second connector portions for unlocking of said first connector portion from said second connector portion.
