A power supply connector has a first part and a second part that are connected to each other such that they can turn relative each other within a predefined and/or restricted turning angle. The first part includes a first set of plurality of conductors and the second part includes a corresponding second set of plurality of conductors, wherein the pairs of conductors are electrically connected by electrical connections including a connection tip on one of the first and the second part and a contact surface on the other one, wherein the electrical connections are provided in at least one circular shape around a turn axis of the power supply connector The turning angle between the first part and the second part is limited to the shortest angular extension of the contact surfaces and the contact surfaces are distributed such that the pair of conductors are permanently electrically connected.
