Abstract
A set of rotary joint components containing stationary part(s) and rotatable part(s) repositionable with respect to each other. The stationary part has a stationary base with means for holding a stationary carrier into a circular-shaped form. The stationary carrier holds at least a stationary transmitter coupler of a contactless data link, such as a strip line. The stationary carrier is made of sheet metal or plastic material, and therefore can easily be prepared on a plane work bench before it is bent to a ring shape.
Claims12
A rotary joint component comprising a stationary part and a rotatable part configured to rotate against the stationary part,
- the rotatable part including a rotatable base holding at least one rotatable receiver coupler,
- the stationary part including a stationary base holding at least one stationary transmitter coupler,
- wherein the at least one stationary transmitter coupler is capacitively coupled to the at least one rotatable receiver coupler,
- wherein the at least one stationary transmitter coupler is mounted to a stationary carrier containing a circularly-shaped sheet of metal or plastic, said sheet being held by the stationary base to have the sheet and at least one stationary transmitter extend transversely to the stationary base.
