A twist-lock connector system comprising: a first twist-lock connector including a first connector housing holding first twist-lock contacts at a first rotate-to-mate interface, the first twist-lock connector including a first high speed electrical connector held by the first connector housing, the first high speed electrical connector including first high speed electrical contacts, the first high speed electrical connector movable relative to the first connector housing between a home position and a rotated position, the first twist-lock connector including a biasing member coupled to the first high speed electrical connector to bias the first high speed electrical connector to the home position; and a second twist-lock connector including a second connector housing holding second twist-lock contacts at a second rotate-to-mate interface, the second twist-lock contacts electrically connected to the first twist-lock contacts to transfer power between the first twist-lock connector and the second twist-lock connector, the second twist-lock connector including a second high speed electrical connector held by the second connector housing, the second high speed electrical connector including second high speed electrical contacts electrically connected to the first high speed electrical contacts to transfer high speed data between the first twist-lock connector and the second twist-lock connector, wherein: the second twist-lock contacts are mated with the first twist-lock contacts along a mating axis and the second high speed electrical contacts are mated with the first high speed electrical contacts along the mating axis with the first high speed electrical connector in the home position, and the second twist-lock contacts are locked to the first twist-lock contacts by rotating the first twist-lock connector in a rotating direction about the mating axis, and as the first twist-lock connector is rotated in the rotating direction the first connector housing rotates relative to the first high speed electrical connector and the first high speed electrical connector does not rotate once being mated with the second high speed electrical connector but it moves from the home position to the rotated position relative to the first connector housing. a first twist-lock connector including a first connector housing holding first twist-lock contacts at a first rotate-to-mate interface, the first twist-lock connector including a first high speed electrical connector held by the first connector housing, the first high speed electrical connector including first high speed electrical contacts, the first high speed electrical connector movable relative to the first connector housing between a home position and a rotated position, the first twist-lock connector including a biasing member coupled to the first high speed electrical connector to bias the first high speed electrical connector to the home position;
