Abstract

A cable connector is provided for coupling to and mounted within the internal cavity of an electrical box for securing an electrical cable passing through an opening in the electrical box. The cable connector includes a body having a first end positioned next to or adjacent the cable opening in the electrical box and a second end spaced from the first end and the cable opening. At least one and typically two retaining members are spring biased from the first end of the body and extend into a cable passage of the body toward the second end. A front wall is provided at the second end of the body with an opening for receiving the wires and forming a stop member to prevent the armor sheathing from passing through the front wall.

First claim

We claim:

1. An electrical box assembly comprising:
an electrical box including a rear wall and a side wall extending from the rear wall, the side wall and the rear wall extending around a partially enclosed portion, the side wall including at least one opening extending therethrough for receiving an electrical cable; a cable retainer supported relative to the electrical box, the cable retainer including a first leg positioned in the partially enclosed portion and a second leg positioned in the partially enclosed portion, the first leg and the second leg overlying at least a portion of the opening, each of the first leg and the second leg including an edge positioned adjacent the opening for gripping an outer surface of the cable passing through the cable opening; and
a wall secured to the electrical box and spaced apart from the first leg and the second leg, the wall including at least one hole aligned with the at least one opening of the electrical box.

2. The electrical box assembly of claim 1 , wherein the first leg is oriented substantially parallel to the second leg, the first leg and the second leg at least partially overlying each other, the edge of the first leg and the edge of the second leg are spaced apart from one another.

3. The electrical box assembly of claim 1 , wherein the first leg and the second leg have different lengths.

4. The electrical box assembly of claim 1 , wherein at least one of the edge of the first leg and the edge of the second leg includes a substantially V-shaped recess aligned with an axis of the opening, the recess engaging an outer surface of the cable and securing the cable against the rear wall of the electrical box.

5. The electrical box assembly of claim 1 , wherein the first leg and the second leg are integrally formed together.

6. The electrical box assembly of claim 1 , wherein the edge of the first leg extends toward the rear wall and is spaced apart from the rear wall by a distance less than a diameter of the cable.

7. The electrical box assembly of claim 1 , wherein the hole of the wall includes a collar extending toward the opening in the side wall of the electrical box.

8. The electrical box assembly of claim 1 , wherein the side wall of the electrical box includes a pair of openings, wherein the cable retainer includes a pair of first legs and a pair of second legs, the first legs separated from one another by a gap such that the first legs are bendable independently of each other, the second legs separated from one another by the gap such that the second legs are bendable independently of one another.

9. An electrical box assembly comprising:
an electrical box including a rear wall and a side wall extending from the rear wall, the side wall and the rear wall at least partially enclosing a cavity, the side wall including a pair of openings extending therethrough, each opening configured to receive an electrical cable; a cable retainer supported relative to the electrical box, the cable retainer including a pair of first legs and a pair of second legs positioned in the cavity, each second leg overlying the associated first leg, the second leg and the associated first leg both overlying at least a portion of the associated opening, each first leg including an edge aligned with the associated opening and extending toward the rear wall, each second leg including an edge aligned with the associated opening and extending toward the rear wall, the first legs spaced apart from each other by a gap such that the first legs are bendable independently of each other, the second legs spaced apart from each other by the gap such that the second legs are bendable independently of each other.

10. The electrical box assembly of claim 9 , further comprising a wall secured to the electrical box and spaced apart from the first legs and the second legs, the wall including a pair of holes, each hole aligned with one of the openings of the electrical box.

11. The electrical box assembly of claim 10 , wherein the wall is formed separate from the cable retainer.

12. The electrical box assembly of claim 9 , wherein each second leg is oriented substantially parallel to the associated first leg, wherein the edge of the second leg and the edge of the associated first leg are spaced apart from one another.

13. The electrical box assembly of claim 9 , wherein each second leg has a different length than the associated first leg.

14. The electrical box assembly of claim 9 , wherein at least one of the edge of each first leg and the edge of each second leg includes a substantially V-shaped recess aligned with an axis of the associated opening, each recess engaging an outer surface of a cable and securing the cable against the rear wall of the electrical box.

15. An electrical box assembly comprising:
an electrical box including a rear wall and a side wall extending from the rear wall, the side wall and the rear wall at least partially enclosing a cavity, the side wall including at least one opening extending therethrough for receiving an electrical cable;
a cable retainer supported relative to the electrical box and positioned entirely within the cavity, the cable retainer including a first leg and a second leg, the first leg and the second leg overlying at least a portion of the opening, each of the first leg and the second leg including an edge positioned adjacent the opening for gripping an outer surface of the cable passing through the cable opening, the first leg oriented substantially parallel to the second leg such that the first leg overlaps at least a portion of the second leg, the edge of the first leg and the edge of the second leg being spaced apart from one another.

16. The electrical box assembly of claim 15 , further comprising a wall secured to the electrical box and spaced apart from the first leg and the second leg, the wall including at least one hole aligned with the at least one opening of the electrical box, the hole having a dimension to allow wires from the cable to pass through while preventing an armor sheath of the cable from passing through.

17. The electrical box assembly of claim 15 , wherein the wall is formed separate from the cable retainer.

18. The electrical box assembly of claim 15 , wherein the first leg and the second leg have different lengths.

19. The electrical box assembly of claim 15 , wherein at least one of the edge of the first leg and the edge of the second leg includes a substantially V-shaped recess aligned with an axis of the opening, the recess engaging an outer surface of the cable and securing the cable against the rear wall of the electrical box.

20. The electrical box assembly of claim 15 , wherein the edge of the first leg extends toward the rear wall, the edge of the first leg being spaced apart from the rear wall by a distance less than a diameter of the cable.
