Abstract: An axially resilient press-in contact pin includes a metal body and an electrically conductive, elastic element. The metal body includes a pin-shaped section and a press-in spring. The press-in spring is on a first end of the pin-shaped section. The elastic element surrounds at least portions of the pin-shaped section and extends beyond a second end (i.e., free end region) of the pin-shaped section.

Abstract: A connecting device includes first and second housing parts which are rotatable relative to one another and are coupled together to define a space therebetween. At least one flexible cable is provided in the space defined by the housing parts. Each cable includes first and second end sections which are configured to be rolled and unrolled in a spiral or helix on associated contact surfaces of the housing parts, respectively. The end sections normally extend in opposite directions from each other circumferentially around the housing parts so that a U-shaped turning area at which cable movement reverses is formed in the space defined by the housing parts. Magnetic areas are arranged on at least one of each cable, the first housing part, and the second housing part to cause the end sections of each cable to removably adhere to the respective contact surfaces of the housing parts.
