Abstract

An elbow with an internal assembly system that includes an elbow body, a cable connection, a first tap, a second tap, a mid-section, a rotating nut and an axial bore. The cable connection adapted to receive a cable having a cable connector, the first tap adapted to receive a first interface device with a threaded stud and the second tap adapted to receive a second interface device. The rotating nut is located in the mid-section and has a threaded bore in communication with the first tap and an opposing closed end with a keyed opening for receiving a tool. The tool is inserted through the axial bore and into the keyed opening to rotate the rotating nut to secure the threaded stud in the rotating nut and secure the cable connector in place.

First claim

I claim:

1. An elbow with an internal assembly system comprising:
an elbow body;
a cable connection adapted to receive a cable having a cable connector;
a first tap having a passage adapted to receive a distal end of a first interface device, the distal end having a threaded stud;
a second tap having a female contact adapted to receive a second interface device,
a mid-section therebetween and a longitudinal axis extending between the first and second taps;
a rotating nut located in the mid-section of the elbow, the rotating nut having a threaded bore in communication with the passage in the first tap and an opposing closed end with a keyed opening configured for receiving a tool; and
an axial bore extending from the keyed opening of the rotating nut to the female contact of the second tap,
wherein the tool is inserted through the axial bore and into the keyed opening to rotate the rotating nut to secure the threaded stud in the rotating nut and secure the cable connector in the elbow body, and wherein the tool is withdrawn from the axial bore and the second interface device is connected to the female contact of the second tap.

2. The elbow according to claim 1 , wherein the first interface device is a 600 amp deadbreak interface and the second interface device 200 amp deadbreak interface.

3. The elbow according to claim 1 , wherein the cable connector is a ring or spade connector.

4. The elbow according to claim 1 , wherein an electrically conductive metal housing of the rotating nut is made of copper.

5. The elbow according to claim 1 , wherein an electrically conductive metal housing of the rotating nut is in electrical contact with the cable connector after the rotating nut is secured to the threaded stud.

6. The elbow according to claim 1 , wherein the keyed opening is a hex broach configured to receive a hex tool.

7. The elbow according to claim 1 , wherein the rotating nut is captured in an electrically conductive metal housing.

8. The elbow according to claim 1 , wherein the cable connector has an opening that is aligned with the longitudinal axis, and wherein the threaded stud of the first interface device is adapted to pass through the cable connector opening into the threaded bore of the rotating nut.

9. The elbow according to claim 1 , wherein the elbow is made of an elastomer material.

10. An elbow with an internal assembly system comprising:
an elbow body;
a cable connection adapted to receive a cable having a cable connector;
a first tap having a passage adapted to receive a distal end of a first interface device having a first amperage rating, the distal end having a threaded stud;
a second tap having a female contact adapted to receive a second interface device having a second amperage rating;
a mid-section therebetween and a longitudinal axis extending between the first and second taps, wherein the first amperage rating is greater than the second amperage rating;
a rotating nut located in the mid-section of the elbow and captured in an electrically conductive metal housing, the rotating nut having a threaded bore in communication with the passage in the first tap and an opposing closed end with a keyed opening configured for receiving a tool; and
an axial bore extending from the keyed opening of the rotating nut to the female contact of the second tap;
wherein the tool is inserted through the axial bore and into the keyed opening to rotate the rotating nut to secure the threaded stud in the rotating nut and secure the cable connector in the elbow body, and wherein the tool is withdrawn from the axial bore and the second interface device is connected to the female contact of the second tap.

11. The elbow according to claim 10 , wherein the first amperage rating is 600 amps and the second amperage rating is 200 amps.

12. The elbow according to claim 10 , wherein the cable connector is a ring or spade connector.

13. The elbow according to claim 10 , wherein the electrically conductive metal housing of the rotating nut is made of copper.

14. The elbow according to claim 10 , wherein the electrically conductive metal housing of the rotating nut is in electrical contact with the cable connector after the rotating nut is secured to the threaded stud.

15. The elbow according to claim 10 , wherein the keyed opening is a hex broach configured to receive a hex tool.

16. The elbow according to claim 10 , wherein the cable connector has an opening that is aligned with the longitudinal axis, and wherein the threaded stud of the first interface device is adapted to pass through the cable connector opening into the threaded bore of the rotating nut.

17. An elbow with an internal assembly system comprising:
an elbow body;
a cable connection adapted to receive a cable having a cable connector with an opening;
a first tap having a passage adapted to receive a distal end of a first interface device having a first amperage rating, the distal end having a threaded stud;
a second tap having a female contact adapted to receive a second interface device having a second amperage rating, wherein the first amperage rating is greater than the second amperage rating;
a mid-section therebetween and a longitudinal axis extending between the first and second taps, wherein the cable connector opening is aligned with the longitudinal axis;
a rotating nut located in the mid-section of the elbow and captured in an electrically conductive metal housing, the rotating nut having a threaded bore in communication with the passage in the first tap and an opposing closed end with a keyed opening configured for receiving a tool, wherein the threaded stud of the first interface device is adapted to pass through the cable connector opening into the threaded bore of the rotating nut, and wherein the electrically conductive metal housing of the rotating nut is in electrical contact with the cable connector after the rotating nut is secured to the threaded stud; and
an axial bore extending from the keyed opening of the rotating nut to the female contact of the second tap;
wherein the tool is inserted through the axial bore and into the keyed opening to rotate the rotating nut to secure the threaded stud in the rotating nut and secure the cable connector in the elbow body, and wherein the tool is withdrawn from the axial bore and the second interface device is connected to the female contact of the second tap.

18. The elbow according to claim 17 , wherein the first amperage rating is 600 amps and the second amperage rating is 200 amps.

19. The elbow according to claim 17 , wherein the cable connector is a ring or spade connector.

20. The elbow according to claim 17 , wherein the keyed opening is a hex broach configured to receive a hex tool.
