Abstract

The present disclosure provides cable glands having an entry portion, an elbow portion and an exit portion. The entry portion includes an entry component. The elbow portion is physically coupled to the entry portion and includes a locking collar, a snap ring and a union elbow. The exit portion is physically coupled to the elbow portion and includes a middle nut, a rubber seal, a seal clamp and a back nut.

First claim

What is claimed is:

1. A cable gland, comprising:
an entry portion, the entry portion including an entry component;
an elbow portion physically coupled to the entry portion, the elbow portion including a locking collar, a snap ring and a union elbow; and
an exit portion physically coupled to the elbow portion, the exit portion including a middle nut, a rubber seal, a seal clamp and a back nut,
wherein the snap ring is positioned within a groove defined in the locking collar and rotatably couples the locking collar to the union elbow.

2. The cable gland according to claim 1 , wherein the entry portion further comprises a potting chamber.

3. The cable gland according to claim 2 , wherein the entry portion further comprises a first O-ring physically coupled between the entry component and the potting chamber.

4. The cable gland according to claim 3 , wherein the elbow portion further comprises a second O-ring physically coupled between locking collar and the union elbow.

5. The cable gland according to claim 4 , wherein the elbow portion further comprises a third O-ring physically coupled between the union elbow and the middle nut.

6. The cable gland according to claim 5 , wherein the exit portion further comprises an armor stop.

7. The cable gland according to claim 6 , wherein armor stop includes a center aperture and the armor stop is physically coupled to the union elbow.

8. The cable gland according to claim 7 , wherein the exit portion includes a grounding spring physically coupled to the union elbow and the middle nut.

9. The cable gland according to claim 8 , wherein an aperture passing through the union elbow is at each point within the union elbow above a predefined minimum diameter.

10. The cable gland according to claim 9 , wherein the union elbow is formed of cast metal machined to have male threads to physically couple to corresponding female threads in the middle nut.

11. The cable gland according to claim 9 , wherein the union elbow has a 90° bend.

12. The cable gland according to claim 9 , wherein the union elbow has a 45° bend.

13. The cable gland according to claim 9 , wherein the rubber seal is formed of an elastomeric material other than rubber.

14. A cable gland, comprising:
an entry portion, the entry portion including an entry component, a potting chamber and a first O-ring physically coupled between the entry component and the potting chamber;
an elbow portion physically coupled to the entry portion, the elbow portion including a locking collar, a union elbow, a second O-ring physically coupled between locking collar and the union elbow and a snap ring physically coupled between locking collar and the union elbow; and
an exit portion physically coupled to the elbow portion, the exit portion including a middle nut, a third O-ring physically coupled between the union elbow and the middle nut, an armor stop physically coupled between the union elbow and the middle nut, a back nut and a rubber seal and a seal clamp physically coupled between the middle nut and the back nut.

15. The cable gland according to claim 14 , wherein the exit portion further comprises an armor stop.

16. The cable gland according to claim 15 , wherein the exit portion is physically coupled to a National Pipe Thread Taper (NPT)-compatible housing.

17. The cable gland according to claim 16 , wherein the National Pipe Thread Taper (NPT)-compatible housing is an electrical junction box.

18. A cable gland, comprising:
an entry portion, the entry portion including an entry component;
an elbow portion physically coupled to the entry portion, the elbow portion including a locking collar, a union elbow, a second O-ring physically coupled between locking collar and the union elbow and a snap ring physically coupled between locking collar and the union elbow; and
an exit portion physically coupled to the elbow portion, the exit portion including a middle nut, a third O-ring physically coupled between the union elbow and the middle nut, an armor stop physically coupled between the union elbow and the middle nut, a back nut and a rubber seal and a seal clamp physically coupled between the middle nut and the back nut.

19. The cable gland according to claim 18 , wherein the entry portion further comprises a potting chamber.

20. The cable gland according to claim 18 , wherein the exit portion further comprises a grounding spring physically coupled between the union elbow and the middle nut.
