Abstract

An electrical switching assembly. The electrical switching assembly includes an integral handle and rotor unit including an integral rotor portion and a handle portion. The rotor portion is configured to receive one or more conductors and is configured to be received in a line base. Assembly methods for electrical switching assemblies are provided, as are other aspects.

First claim

What is claimed is:

1. An electrical switching assembly, comprising:
an integral handle and rotor unit including a rotor portion integral with a handle portion;
one or more orientation features on the rotor portion; and
a line base comprising one or more openings configured to receive the one or more orientation features, wherein the one or more orientation features enable the rotor portion to be received within the line base when the rotor portion is in a predetermined orientation relative to the line base,
wherein the one or more orientation features are configured to retain the rotor portion within the line base without needing any additional retaining mechanisms in the electrical switching assembly,
wherein the rotor portion configured to receive one or more conductors, and
wherein the rotor portion configured to be received in the line base.

2. The electrical switching assembly of claim 1 , comprising:
one or more conductors extending radially through the rotor portion,
wherein the rotor portion is configured to be rotatable about a central axis when the rotor portion is received within the one or more openings; and
one or more terminals in the line base, wherein the one or more conductors are configured to electrically contact the one or more terminals in response to rotation of the rotor portion.

3. The electrical switching assembly of claim 2 , wherein one or more orientation features includes one or more curved portions extending from the rotor portion.

4. The electrical switching assembly of claim 2 , wherein one or more orientation features includes a first flat surface.

5. The electrical switching assembly of claim 2 , wherein one or more orientation features includes a first flat surface and a second flat surface.

6. The electrical switching assembly of claim 5 , wherein the first flat surface is parallel to the second flat surface.

7. The electrical switching assembly of claim 2 , wherein the one or more orientation features includes one or more lobes extending from the rotor portion.

8. The electrical switching assembly of claim 7 , wherein one or more lobes extend further from the rotor portion than other elements of the rotor portion.

9. The electrical switching assembly of claim 2 , wherein the line base comprises one or more stops configured to contact the one or more conductors extending through the rotor portion in response to the integral handle and rotor unit rotating to a predetermined position.

10. The electrical switching assembly of claim 2 , wherein the one or more orientation features are configured to prevent the integral handle and rotor unit from being removed from the line base when the integral handle and rotor unit is in a position other than the predetermined position.

11. The electrical switching assembly of claim 2 , wherein the rotor portion includes an extension opposite the handle portion, wherein the line base includes a bore, and wherein the extension is received in the bore.

12. The electrical switching assembly of claim 1 , wherein the integral handle and rotor unit is made of an insulating material.

13. The electrical switching assembly of claim 1 , further comprising an enclosure including an interior and an opening between the interior and an exterior of the enclosure, wherein a line base is within the interior, wherein the rotor portion is received within the opening, and wherein the handle portion is exterior to the enclosure.

14. An electrical switching assembly comprising:
an enclosure including an interior and an enclosure opening extending between the interior and an exterior of the enclosure;
an integral handle and rotor unit including a rotor portion integral with a handle portion, the rotor portion being received in the enclosure opening;
one or more conductors extending radially through the rotor portion;
one or more orientation features on the rotor portion;
a line base within the interior of the enclosure including one or more line base openings configured to receive the one or more orientation features when the integral handle and rotor unit is oriented in a predetermined position relative to the line base, wherein the rotor portion is configured to be rotatable about a central axis when the rotor portion is received within the one or more line base openings,
wherein the one or more orientation features are configured to retain the rotor portion within the line base without needing any additional retaining mechanisms in the electrical switching assembly; and
one or more terminals in the line base, wherein the one or more terminals are configured to contact the one or more conductors in response to rotation of the integral handle and rotor unit.

15. The electrical switching assembly of claim 14 , wherein the one or more orientation features includes one or more lobes extending from the rotor portion.

16. The electrical switching assembly of claim 15 , wherein one or more lobes extend further from the rotor portion than other elements of the rotor portion.

17. A method of assembling a switching assembly, comprising:
providing an integral handle and rotor unit including a handle portion integral with a rotor portion, the rotor portion including one or more holes extending through the rotor portion;
providing a line base comprising one or more openings configured to receive the rotor portion;
providing one or more orientation features on the rotor portion, wherein the one or more orientation features enable the rotor portion to be received within the line base when the rotor portion is in a predetermined orientation relative to the line base and wherein the one or more orientation features are configured to retain the rotor portion within the line base without needing any additional retaining mechanisms in the switching assembly;
providing one or more electrical terminals within the line base;
rotating the rotor portion to a first position, wherein the rotor portion is receivable in the one or more openings when the rotor portion is in the first position;
inserting the rotor portion into the line base; and
inserting a conductor into at least one of the one or more openings in the rotor portion, wherein each conductor is configured to electrically contact the one or more electrical terminals in response to rotation of the rotor portion.

18. The method of claim 17 , further comprising rotating the rotor portion to a second position prior to inserting a conductor into at least one of the one or more openings in the rotor portion.

19. The method of claim 17 , further comprising:
providing an enclosure; and
affixing the line base within the enclosure.

20. The method of claim 19 , wherein providing an enclosure comprises providing an enclosure including an enclosure opening between an interior of the enclosure and an exterior of the enclosure, and further comprising inserting the rotor portion through the enclosure opening.
