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 having a cable opening configured to receive an electrical cable, the rear wall and side wall at least partially defining an internal cavity;
a cable connector secured to the electrical box, the cable connector including a cable passage aligned with the cable opening of the side wall, the cable passage defining an axis, the cable connector further including a body having a first end positioned adjacent the cable opening on an inner surface of the electrical box and a second end opposite the first end, the second end spaced apart from the inner surface and positioned within the internal cavity, the cable passage extending through the first end and the second end;
a first cable retainer connected to the body and extending toward the axis of the cable passage, the first cable retainer configured to engage an outer surface of the cable and secure the cable against movement relative to the rear wall of the electrical box in a direction toward the cable opening; and
a second cable retainer connected to the body and extending toward the axis of the cable passage.

2. The electrical box assembly of claim 1 , wherein the cable connector further comprises a first side wall on a first side of the cable passage and a second side wall on a second side of the cable passage, wherein the first cable retainer extends from the first side wall and the second cable retainer extends from the second side wall.

3. The electrical box assembly of claim 2 , wherein the first cable retainer is integrally formed with the first side wall and the second cable retainer is integrally formed with the second side wall.

4. The electrical box assembly of claim 2 , wherein the first cable retainer is coupled to the first side wall by a U-shaped portion to spring bias the first cable retainer inwardly toward the cable passage, and the second cable retainer is coupled to the second side wall by a U-shaped portion to spring bias the second cable retainer inwardly toward the cable passage.

5. The electrical box assembly of claim 1 , wherein the body has a wall extending between the first end and second end, and wherein the first cable retainer and the second cable retainer are coupled to the wall.

6. The electrical box assembly of claim 1 , further comprising a leg positioned between the first cable retainer and the second cable retainer, the leg coupled to the first end of the body and extending into the cable passage, the leg configured to grip the electrical cable.

7. The electrical box assembly of claim 1 , wherein the cable connector further comprises
a wall extending between the first end and the second end of the body;
a leg coupled to the wall proximate the first end of the body and extending between the first cable retainer and the second cable retainer toward the second end of the body and toward the axis of the cable passage and being configured to engage an outer surface of the cable.

8. The electrical assembly of claim 1 , wherein the cable connector includes a wall extending between the first end of the body and the second end of the body, wherein the first and second cable retainers are coupled to the wall.

9. The electrical box of claim 1 , wherein the cable connector is secured relative to the electrical box by a fastener, the fastener extending normal to the rear wall of the electrical box.

10. The electrical box of claim 1 , wherein the cable connector includes a surface positioned adjacent the second end of the body, the surface configured to abut a sheath of the cable to prevent the sheath from passing through the second end of the body.

11. A cable connector for securing at least one electrical cable extending through an opening in an electrical box, the cable connector comprising:
a body including a cable passage, a first end configured to be positioned in the electrical box adjacent the cable opening, and a second end opposite the first end, the second end positioned within the electrical box, the body further including at least one wall extending between the first end of the body and the second end of the body;
a first cable retainer connected to the body and including a free end for gripping an outer surface of the electrical cable, the first cable retainer being integrally formed with the wall; and
a second cable retainer connected to the body and including a free end for gripping the outer surface of the electrical cable, and the second cable retainer being integrally formed with the wall.

12. The cable connector of claim 11 , wherein the at least one wall includes a first side wall and a second side wall, wherein the first cable retainer is coupled to the first side wall by a spring U-shaped portion, and wherein the first cable retainer has a first leg portion extending from the first end toward the cable passage and a second leg portion extending from the first leg portion toward the cable passage, wherein the second cable retainer is coupled to the second side wall by a spring U-shaped portion, and wherein the second cable retainer has a first leg portion extending from the first end toward the cable passage and a second leg portion coupled to and extending from the first leg portion toward the cable passage.

13. The cable connector of claim 12 , further comprising
a rear wall positioned proximate the first end of the body and having an opening for receiving the electrical cable; and
a leg coupled to the rear wall and extending toward the second end of the body between the first cable retainer and the second cable retainer and extending toward the axis of the cable passage.

14. The cable connector of claim 11 , wherein the body further comprises
a top wall extending between the first end and the second end of the body;
a rear wall at the first end of the body and wherein the first cable retainer and second cable retainer are coupled to the top wall; and
a leg coupled to the top wall and positioned between the cable retainers and extending toward the front wall and toward the axis of the cable passage.

15. The cable connector of claim 11 , wherein the body further comprises
a bottom wall extending between the first end and the second end, and where the cable retainers extend upwardly from the bottom wall toward the front wall;
a top wall extending between the first end and the second end of the body; and
a leg extending from the top wall toward the front wall and toward the axis of the cable passage, the leg being positioned between the first cable retainer and the second cable retainer.

16. The cable connector of claim 11 , wherein the body is secured relative to the electrical box by a fastener, the fastener extending perpendicular to an axis of the cable passage.

17. The cable connector of claim 11 , further comprising a surface positioned adjacent the second end of the body, the surface configured to abut a sheath of the cable to prevent the sheath from passing through the second end of the body.

18. A cable connector for securing at least one electrical cable extending through an opening of an electrical box, the cable connector comprising:
a body including a cable passage, a first end for positioning in the electrical box adjacent the cable opening, and a second end opposite the first end;
a front wall at the second end of the body and having an aperture for receiving the at least one electrical cable, the aperture having a dimension so that the front wall is configured to abut a sheath of the cable such that a plurality of conductors pass thro
