Description

This invention relates to connectors and connector assemblies. Patent Document 1 below discloses a conventional connector for a power supply device. This connector comprises a conductive shell, multiple terminals, an insulating body, an internal circuit board, multiple current sensors, and multiple signal lines. The shell is substantially cylindrical. The multiple terminals are metal plates extending axially from the shell, each having a tip, middle, and rear end. The body holds the middle portions of the multiple terminals at intervals approximately perpendicular to the axial direction and is housed within the shell along with the tip and middle portions of the multiple terminals. The internal circuit board is held by the body and positioned below the middle portions of the multiple terminals. The multiple current sensors are mounted on the internal circuit board and are GMR (Giant Magneto Resistive Effect) sensors that detect the magnetic fields generated by the currents flowing through the multiple terminals. The multiple signal lines are electrically connected to the multiple current sensors via the internal circuit board and are led out from the body and shell.
