Abstract

An electromechanical actuating drive ( 1 ) having a servomotor ( 2 ) arranged so that the servomotor ( 2 ) can rotate about its longitudinal axis in a vehicle, and a cable harness ( 3 ) having first and second ends. A first end of the harness ( 3 ) is connected to the servomotor ( 2 ) and the harness ( 3 ) extends, in an elastically deformable arc, from the first end to the second end. The second end of the harness ( 3 ) is positionally fixed in the vehicle. The second end of the cable harness ( 3 ) is clamped in a securing and deflecting device at a transfer point ( 5 ).

First claim

a securing and deflecting device having first and second insert components which couple to clamp the second end of the cable harness therebetween;
a clamping and holding plate comprising first and second planar arms that extend at least substantially parallel to each other; and
the first and the second planar arms of the clamping and holding plate receiving the first and the second insert components of the securing and deflecting device therebetween and clamping the first and the second insert components to each other to clamp the second end of the cable harness between the first and the second insert components.

2. The electromechanical actuating drive according to claim 1 , wherein the securing and deflecting device having an inlet side through which the cable harness extends from the securing and deflecting device to the servomotor.

3. The electromechanical actuating drive according to claim 2 , wherein the clamping and holding plate being fixable to vehicle independent of the first and the second insert components.

4. The electromechanical actuating drive according to claim 3 , wherein the clamping and holding plate has fixing means for fixing the clamping and holding plate to the vehicle, and the fixing means are tabs that extend from the first and the second planar arms such that fixing holes of the tabs of the first planar arm align with fixing holes of the tabs of the second planar arm.

5. The electromechanical actuating drive according to claim 2 , wherein the cable harness comprises individual cables and the individual cables are laid between the first and the second insert components, and the first and the second insert components have guide grooves for holding and deflecting the individual cables, the guide grooves are aligned such that, on the inlet side of the securing and deflecting device, the individual cables are arranged parallel to each other in only one plane.

6. The electromechanical actuating drive according to claim 1 , wherein the securing and deflecting device has an inlet side and first and second outlet sides, the cable harness comprises a plurality of cables, and the plurality of cables extend from the servomotor in through the inlet side of the securing and deflecting device and out through the first outlet side of the securing and deflecting device.

7. The electromechanical actuating drive according to claim 6 , wherein the plurality of cables, on the inlet side, are arranged in only one plane and, on the first outlet side, the plurality of cables are deflected and arranged in at least two planes.

8. The electromechanical actuating drive according to claim 7 , wherein a deflection angle, between a direction of the plurality of cables on the inlet side and a direction of the plurality of cables on the first outlet side, is approximately 90 degrees.

9. The electromechanical actuating drive according to claim 3 , wherein the clamping and holding plate is made by bending a planar sheet to form a U-shaped stirrup with the first and the second planar arms being connected by a curved plate segment.

10. The electromechanical actuating drive according to claim 9 , wherein the first and the second planar arms each have a punched-out portion forming a tab which engages in a recess in a corresponding one of the first and the second insert components.

11. The electromechanical actuating drive according to claim 9 , wherein fixing holes are arranged at a remote end of each of the first and the second planar arms, and each of the first and the second insert components has two through-holes, which align with the fixing holes of the first and the second planar arms.

12. The electromechanical actuating drive according to claim 11 , wherein the curved plate segment comprises a tab that extends therefrom and is coplanar with the first planar arm, and the tab of the curved plate segment comprises a further fixing hole.

13. The electromechanical actuating drive according to claim 11 , wherein either spacer sleeves or threaded sleeves are insertable into the through-holes.

14.
