Claims16
A rotary joint, including a hollow gear and a hollow wiring unit having a first flexible printed circuit board therein, to allow hose to pass through both the hollow gear and the hollow wiring unit;
- wherein the hollow wiring unit includes a first rotation member and a second rotation member rotatable relative to each other, and first portion of the first flexible printed circuit board is connected to the first rotation member and second portion of the first flexible printed circuit board is connected to the second rotation member.
A rotary joint, including a hollow gear and a hollow wiring unit having a first flexible printed circuit board therein, to allow hose to pass through both the hollow gear and the hollow wiring unit;
- wherein the first flexible printed circuit board is bent at one or more bending portions to form at least a first portion laid in a first plane and a second portion laid in a second plane, and as a first rotation member rotates with respect to a second rotation member, at least one of bending portions shifts along the first flexible printed circuit board;
- wherein a shape of the first flexible printed circuit board prior to bending comprises a broken ring or partial ring.
A rotary joint, including a hollow gear and a hollow wiring unit having a first flexible printed circuit board therein, to allow hose to pass through both the hollow gear and the hollow wiring unit;
- wherein the first flexible printed circuit board is bent at one or more bending portions to form at least a first portion laid in a first plane and a second portion laid in a second plane, and as a first rotation member rotates with respect to a second rotation member, at least one of bending portions shifts along the first flexible printed circuit board;
- wherein the first rotation member is rotatable with respect to the second rotation
- member around a rotation axis substantially perpendicular to at least one of the first plane and the second plane;
- wherein the first plane and the second plane are substantially parallel;
- and
- wherein the first rotation member is a first half case and the second rotation member is a second half case, wherein the first half case rotatably couples to the second half case, thereby enclosing at least the first flexible printed circuit board.
