Abstract

An electrical chamber can include at least one wall forming a cavity, where the at least one wall includes a first end and a wall inner surface. The electrical chamber can also include a first isolation zone disposed on the inner surface at a first distance from the first end, where the first isolation zone is formed by a first proximal wall, a first distal wall, and a first isolation zone inner surface disposed between and adjacent to the first proximal wall and the first distal wall, where the first proximal wall forms a first angle with the first isolation zone inner surface, where the first distal wall forms a second angle with the first isolation zone inner surface, where the first angle is non-perpendicular. The cavity is configured to receive at least one electrical conductor. The cavity and the first isolation zone are configured to receive a potting compound.

First claim

What is claimed is:

1. An electrical connector end, comprising:
at least one wall forming a cavity, wherein the at least one wall comprises a first end and a wall inner surface; and
a first isolation zone disposed on the wall inner surface at a first distance from the first end along an inner perimeter of the wall inner surface, wherein the first isolation zone is formed by a first proximal wall, a first distal wall, and a first isolation zone inner surface disposed between and adjacent to the first proximal wall and the first distal wall, wherein the first proximal wall forms a first angle with the first isolation zone inner surface, wherein the first distal wall forms a second angle with the first isolation zone inner surface, wherein the first angle is non-perpendicular,
wherein the cavity is configured to receive at least one electrical conductor, and
wherein the cavity and the first isolation zone are configured to receive a potting compound, wherein the first isolation zone is not configured to receive another electrical connector end, and
wherein the first isolation zone forms a continuous ring around the wall inner surface at the first distance from the first end along the circumference of the wall inner surface.

2. The electrical connector end of claim 1 , wherein the first proximal wall forms a third angle with the wall inner surface of the at least one wall, and wherein the distal wall forms a fourth angle with the wall inner surface of the at least one wall.

3. The electrical connector end of claim 1 , wherein the first isolation zone inner surface is substantially parallel to the wall inner surface.

4. The electrical connector end of claim 1 , wherein the first isolation zone inner surface is recessed into the at least one wall relative to the wall inner surface.

5. The electrical connector end of claim 1 , wherein the first angle is acute.

6. The electrical connector end of claim 5 , wherein the second angle is acute.

7. The electrical connector end of claim 5 , wherein the second angle is obtuse.

8. The electrical connector end of claim 1 , wherein the first angle is obtuse.

9. The electrical connector end of claim 1 , further comprising:
a second isolation zone disposed on the wall inner surface at a second distance from the first end, wherein the second isolation zone is formed by a second distal wall, a second proximal wall, and a second isolation zone inner surface disposed between and adjacent to the second distal wall and the second proximal wall.

10. The electrical connector end of claim 9 , wherein the second proximal wall and the first distal wall are disposed on opposite sides of and adjacent to a first transition surface.

11. The electrical connector end of claim 10 , wherein the first transition surface is part of the wall inner surface of the at least one wall.

12. The electrical connector end of claim 10 , wherein the first transition surface and the first distal wall meet at a rounded joint.

13. The electrical connector end of claim 9 , wherein the second distance is greater than the first distance.

14. The electrical connector end of claim 1 , wherein the at least one wall portion comprises a first wall portion and a second wall portion, wherein the first wall portion is coupled to the second wall portion, wherein the first wall portion and the second wall portion, when coupled to each other, form the first isolation zone.

15. The electrical connector end of claim 14 , wherein the first wall portion and the second wall portion are coupled to each other using mating threads.

16. The electrical connector end of claim 14 , wherein the first wall portion and the second wall portion, when coupled to each other, form a flame path therebetween.

17. The electrical connector end of claim 14 , wherein the at least one wall portion further comprises a third wall portion, wherein the first wall portion is coupled to the third wall portion, wherein the first wall portion and the third wall portion, when coupled to each other, form a second isolation zone.

18. The electrical connector end of claim 17 , wherein the second isolation zone comprises a second isolation zone inner surface disposed between and adjacent to a second distal wall and a second proximal wall, wherein the second proximal wall forms a third angle with the second isolation zone inner surface, wherein the second distal wall forms a fourth angle with the second isolation zone inner surface, wherein the third angle is non-perpendicular, and wherein the third angle differs from the first angle of the first isolation zone.

19. The electrical connector end of claim 17 , wherein decoupling the second wall portion from the first wall portion results in a third isolation zone, wherein the third isolation zone is formed by the first wall portion and the third wall portion.

20. An electrical connector assembly, comprising:
an electrical connector end, comprising:
at least one wall forming a cavity, wherein the at least one wall comprises a first end and a wall inner surface; and
a first isolation zone disposed on the wall inner surface at a first distance from the first end along an inner perimeter of the wall inner surface, wherein the first isolation zone is formed by a first proximal wall, a first distal wall, and a first isolation zone inner surface disposed in between and adjacent to the first proximal wall and the first distal wall, wherein the first proximal wall forms a first angle with the first isolation zone inner surface, wherein the first distal wall forms a second angle with the first isolation zone inner surface, wherein the first angle is non-perpendicular;

at least one electrical conductor disposed within the cavity; and
a potting compound disposed around the at least one conductor within the cavity and the first isolation zone,
wherein the first isolation zone does not receive another electrical connector end.
