Abstract

A connecting element between a motor and a control unit includes a flat base plate having contact elements and an, in particular centered, opening. The base plate further includes a shaft around the opening. A first seal is provided at the edge of the base plate and a second seal is provided at the upper edge of the shaft.

First claim

What is claimed is:

1. A connecting element between a motor and a control unit, comprising:
a flat base plate including contact elements configured to electrically connect the motor to the control unit, an opening, and a shaft around the opening extending from a face of the flat base plate that faces away from the motor,
wherein a first seal is provided at an edge of the flat base plate and a second seal is provided at an upper edge of the shaft.

2. The connecting element according to claim 1 , wherein the contact elements each have a third seal.

3. The connecting element according to claim 2 , wherein the third seal projects at least partially beyond a side of the flat base plate.

4. The connecting element according to claim 2 , wherein the third seals are each press-in seals.

5. The connecting element according to claim 1 , wherein the flat base plate has a round shape, and the first seal is an O-ring.

6. The connecting element according to claim 1 , wherein:
the flat base plate defines a recess in an edge region of the flat base plate, and
the first seal is inserted into said recess.

7. The connecting element according to claim 1 , wherein the shaft has a round shape, and the second seal is an O-ring.

8. The connecting element according to claim 7 , wherein the second seal is arranged in an outer region of the shaft.

9. The connecting element according to claim 1 , wherein the opening is centered in the flat base plate.

10. An assembly comprising:
a motor;
a control unit configured to electrically connect to the motor; and
a connecting element including (i) a flat base plate, (ii) contact elements configured to electrically connect the motor to the control unit and (iii) an opening;
wherein the flat base plate has a shaft around the opening extending from a face of the flat base plate that faces away from the motor,
wherein the motor includes an upper recessed region, the connecting element and the control unit positioned in the upper recessed region of the motor,
wherein the connecting element is introduced into the recessed region, and
wherein a first seal is provided at an edge of the flat base plate and a second seal is provided at an upper edge of the shaft.

11. The assembly according to claim 10 , wherein each of the contact elements is configured to provide a separate electrical connection between the control unit and the motor.

12. The assembly according to claim 10 , wherein the seals prevent liquid being exchanged between the upper region in the motor and the control unit.

13. The assembly according to claim 10 , wherein the opening is centered in the flat base plate.
