Abstract

An electrical connector assembly may include a yoke that includes an outer housing; and a central conductor provided within the outer housing, wherein the central conductor comprises at least three outwardly extending portions. A first outwardly extending portion and a second outwardly extending portion are operatively coupled to first and second power cables, respectively. A third outwardly extending portion comprises a tap configured to interchangeably interface with a sacrificial appendage and a grounding element. When the sacrificial appendage is installed on the tap, the sacrificial appendage is configured to be cut through to confirm that the electrical connector assembly is de-energized. When the grounding element is installed on the tap, the grounding element is configured for attachment to a grounded hot line clamp to ground the electrical connector assembly.

Claims (52)

1. An electrical connector assembly, comprising:

a yoke, comprising:

an outer housing; and

a central conductor provided within the outer housing,

wherein the central conductor comprises at least three outwardly extending portions,

wherein a first outwardly extending portion and a second outwardly extending portion are operatively coupled to first and second power cables, respectively, and

wherein a third outwardly extending portion comprises a tap configured to interchangeably interface with a sacrificial appendage and a grounding element,

wherein, when the sacrificial appendage is installed on the tap, the sacrificial appendage is configured to be cut through to confirm that the electrical connector assembly is de-energized, and

wherein, when the grounding element is installed on the tap, the grounding element is configured for attachment to a grounded hot line clamp to ground the electrical connector assembly.

2. The electrical connector assembly of claim 1 , wherein the sacrificial appendage comprises a sacrificial cap, and

wherein the yoke is configured to releasably retain each of the sacrificial cap and the grounding element in conductive contact with the tap.

3. The electrical connector assembly of claim 2 , wherein the sacrificial cap includes an insulated outer body and a sacrificial conductor configured to conductively communicate with the central conductor of the yoke.

4. The electrical connector assembly of claim 3 , wherein the sacrificial cap comprises a cavity for receiving an insulated outer portion of the tap.

5. The electrical connector assembly of claim 3 , wherein at least portions of the outer housing of the yoke and the outer body of the sacrificial cap comprise a semi-conductive outer shield.

6. The electrical connector assembly of claim 3 , wherein the sacrificial cap comprises a cut-through portion that includes at least a portion of the sacrificial conductor.

7. The electrical connector assembly of claim 6 , wherein the outer body of the sacrificial cap comprises graphical indicia indicating a location of the cut-through portion.

8. The electrical connector assembly of claim 1 , wherein the grounding element comprises:

a grounding cap comprising:

an insulated body; and

a conductive core extending through the insulated body,

wherein the conductive core is configured to conductively communicate with the central conductor of the yoke, and

wherein a portion of the conductive core projects beyond the insulated body to form a grounding interface portion.

9. The electrical connector assembly of claim 8 , wherein the insulated body of the grounding cap comprises a cavity for receiving an insulated outer portion of the tap.

10. The electrical connector assembly of claim 8 , wherein the tap of the yoke and the conductive core of the grounding cap comprise mating threaded interfaces for securing the grounding cap to the tap.

11. The electrical connector assembly of claim 8 , wherein the grounding interface portion comprises a generally cylindrical configuration for engaging clamping members of the hot line clamp.

12. The electrical connector assembly of claim 8 , wherein the grounding interface portion comprises a ball configuration for engaging a ball socket in the hot line clamp.

13. The electrical connector assembly of claim 1 , wherein the grounding element comprises:

a grounding pin comprising:

a tap engaging portion configured to conductively communicate with the central conductor of the yoke, and

a clamp engaging portion configured to engage the hot line clamp.

14. The electrical connector assembly of claim 13 , wherein the tap of the yoke and the tap engaging portion of the grounding pin comprise mating threaded interfaces for securing the grounding pin to the tap.

15. The electrical connector assembly of claim 14 , wherein the grounding pin comprises a tool engaging portion to facilitate coupling of the grounding pin to the tap.

16. The electrical connector assembly of claim 13 , wherein the clamp engaging portion comprises at least one of a cylindrical configuration or a ball configuration for engaging the hot line clamp.

17. The electrical connector assembly of claim 1 , wherein the yoke comprises a three-way yoke, a four-way yoke, or a two-way yoke.

18. A medium or high voltage electrical connector assembly, comprising:

a yoke, comprising:

an insulated inner housing;

a semi-conductive outer shield; and

a central conductor provided within the inner housing,

wherein the central conductor comprises:

at least two outwardly extending portions for engaging load power cables or supply power cables; and

a tap portion that projects from the outer shield of the yoke for interchangeably engaging a sacrificial cap and a grounding element,

wherein a portion of the insulated inner housing surrounds the tap portion in a tubular manner to engage a respective portion of the sacrificial cap,

wherein the sacrificial cap includes an insulated body, a semi-conductive outer shield, and a sacrificial conductor configured to conductively communicate with the central conductor of the yoke via the tap portion,

wherein the sacrificial cap comprises a cut-through portion that includes at least a portion of the sacrificial conductor,

wherein the grounding element includes a substantially cylindrical conductor configured to engage the tap portion and a hot line clamp for grounding the electrical connector assembly.

19. The medium or high voltage electrical connector assembly of claim 18 , wherein the grounding element comprises:

a grounding cap comprising:

an outer housing; and

wherein the substantially cylindrical conductor extends through the outer housing to form an exposed clamp engaging portion, and

wherein the outer housing comprises a cavity for engaging the portion of the insulated inner housing that surrounds the tap portion.

20. The medium or high voltage electrical connector assembly of claim 13 , wherein the substantially cylindrical conductor of the grounding element comprises a ball end for engaging a ball socket in the hot line clamp.
