Abstract

Embodiments of an angled electrical contactor are provided. An aspect includes a moving contact bar including at least 4 contact discs, wherein a first contact disc and a second contact disc of the moving contact bar are located in a first plane, and a third contact disc and a fourth contact disc of the moving contact bar are located in a second plane, wherein the first plane and the second plane are distinct and are at an angle to each other. Another aspect includes a first stationary contact bar including at least 2 contact discs, wherein a first contact disc of first stationary contact bar is in a third plane, the third plane being substantially parallel to the first plane, and a second contact disc of the first stationary contact bar is in a fourth plane, the fourth plane being substantially parallel to the second plane.

First claim

a first stationary contact bar, the first stationary contact bar comprising at least 2 contact discs, wherein a first contact disc of first stationary contact bar is in a third plane, the third plane being substantially parallel to the first plane, and a second contact disc of the first stationary contact bar is in a fourth plane, the fourth plane being substantially parallel to the second plane; and
an actuating device moving the moving contact bar via a spring towards and away from the first stationary contact bar.

2. The angled electrical contactor of claim 1 , wherein the angle is between about 1° and about 179°.

3. The angled electrical contactor of claim 2 , wherein the angle is between about 60° and about 120°.

4. The angled electrical contactor of claim 1 , further comprising a second stationary contact bar, the second stationary contact bar comprising at least 2 contact discs, wherein a first contact disc of the second stationary contact bar is in the third plane, and a second contact disc of the second stationary contact bar is in the fourth plane.

5. The angled electrical contactor of claim 4 , wherein the moving contact bar is configured to move towards and away from the first stationary contact bar and the second stationary contact bar by the actuating device, wherein the first contact disc of the moving contact bar is configured to contact the first contact disc of the first stationary contact bar, wherein the second contact disc of the moving contact bar is configured to contact the second contact disc of the first stationary contact bar, wherein the third contact disc of the moving contact bar is configured to contact the first contact disc of the second stationary contact bar, and wherein the fourth contact disc of the moving contact bar is configured to contact the second contact disc of the second stationary contact bar such that a current flows through the angled electrical contactor through the first stationary contact bar, the moving contact bar, and the second stationary contact bar.

6. The angled electrical contactor of claim 5 , further comprising a first current input on the first stationary contact bar, and a first current output on the second stationary contact bar.

7.

8. The angled electrical contactor of claim 7 , further comprising:
a third stationary contact bar, the third stationary contact bar comprising at least 2 contact discs, wherein a first contact disc of third stationary contact bar is in a seventh plane, the seventh plane being substantially parallel to the fifth plane, and a second contact disc of the third stationary contact bar is in a eighth plane, the eighth plane being substantially parallel to the sixth plane; and
a fourth stationary contact bar, the fourth stationary contact bar comprising at least 2 contact discs, wherein a first contact disc of the fourth stationary contact bar is in the seventh plane, and a second contact disc of the fourth stationary contact bar is in the eighth plane.

9. The angled electrical contactor of claim 8 , wherein the moving contact bar is configured to move towards and away from the first stationary contact bar and the second stationary contact bar by the actuating device, wherein the fifth contact disc of the moving contact bar is configured to contact the first contact disc of the third stationary contact bar, wherein the sixth contact disc of the moving contact bar is configured to contact the second contact disc of the third stationary contact bar, wherein the seventh contact disc of the moving contact bar is configured to contact the first contact disc of the fourth stationary contact bar, and wherein the eighth contact disc of the moving contact bar is configured to contact the second contact disc of the fourth stationary contact bar such that a current flows through the angled electrical contactor through the third stationary contact bar, the moving contact bar, and the fourth stationary contact bar.

10. The angled electrical contactor of claim 9 , further comprising a first current input on the first stationary contact bar, and a first current output on the second stationary contact bar, a second current input on the third stationary contact bar, and a second current output on the fourth stationary contact bar.

11. The angled electrical contactor of claim 1 , wherein the first stationary contact bar comprises at least 4 contact discs, and wherein a third contact disc of the first stationary contact bar is in the third plane, and a second contact disc of the first stationary contact bar is in the fourth plane.

12. The angled electrical contactor of claim 11 , wherein the moving contact bar is configured to move towards and away from the first stationary contact bar by the actuating device, wherein the first contact disc of the moving contact bar is configured to contact the first contact disc of the first stationary contact bar, wherein the second contact disc of the moving contact bar is configured to contact the second contact disc of the first stationary contact bar, wherein the third contact disc of the moving contact bar is configured to contact the third contact disc of the first stationary contact bar, and wherein the fourth contact disc of the moving contact bar is configured to contact the fourth contact disc of the first stationary contact bar such that a current flows through the angled electrical contactor through the first stationary contact bar and the moving contact bar.
