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 housing 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 cable retaining members are positioned in the cable opening of the housing between the front wall and the rear wall. The cable retainer has a body with a plurality of retaining arms extending into an axial passage of the body for gripping the outer surface of a cable.

First claim

What is claimed is:

1. A cable connector for coupling a cable to an electrical box, said cable connector configured for mounting entirely within a cavity of the electrical box, said cable connector comprising:
a front wall having a cable opening forming a cable passage oriented for aligning with a cable opening in the electrical box and for positioning entirely with the cavity of the electrical box; and
a cable retainer received in said opening in said front wall, said cable retainer having a body with a cable passage aligned with said cable opening in said front wall for receiving the electrical cable, said cable retainer having a spring biased member configured for gripping an outer surface of the cable and retaining the cable within the cable passage of the cable retainer.

2. The cable connector of claim 1 , wherein said body of said cable has a substantially annular shape and has at least one outwardly extending portion extending from a first end of said body, said outwardly extending portion contacting an outer surface of said first wall, and where said body extends through said cable opening in said first wall and extends from an inner surface of said first wall.

3. The cable connector of claim 2 , wherein
said spring biased retaining member is at least one spring biased retaining arm extending from said body into said cable passage for contacting the cable to prevent removal of the cable from said cable retainer.

4. The cable connector of claim 1 , further comprising
a collar on an inner surface of said front wall, and where said cable retainer is received in an axial passage of said collar.

5. The cable connector of claim 1 , wherein
said body of said cable retainer has a substantially cylindrical configuration with an axial passage; and
said body has a plurality of arms extending into said axial passage and oriented for gripping the cable received said axial passage, and a plurality of outwardly extending tabs for contacting an outer surface of said front wall.

6. The cable connector of claim 1 , further comprising
a rear wall spaced from said front wall and having a cable opening aligned with said cable opening in said front wall, and a connecting wall extending between said front wall and rear wall;
said spring biased member comprising two spaced apart legs to define a cable passage through said cable retainer, said legs being spaced apart a distance to grip the cable, and where said cable retainer is received in said connecting wall for sliding between a first position to allow the cable to pass through and a second position to grip the cable.

7. The cable connector of claim 1 , further comprising
a collar extending from said first wall and having a dimension to receive the cable, and
said spring biased member is an annular spring positioned in said collar and having a central opening for receiving the cable, and said spring being configured to grip an outer surface of said cable.

8. An electrical box assembly comprising:
an electrical box having a rear wall and a side wall, said side wall having at least one cable opening with a dimension for receiving a cable;
a front wall coupled to said electrical box, said front wall having a cable opening aligned with said cable opening in said electrical box and defining a cable passage for receiving the cable; and
a cable retainer received in said cable passage, said cable retainer having a body with an axial passage for receiving the electrical cable, said body having at least one spring biased retaining arm oriented for gripping an outer surface of the cable, said front wall and cable retainer being positioned entirely within a cavity of said electrical box.

9. The electrical box assembly of claim 8 , wherein
said body of said cable retainer has an outwardly extending portion at a first end of said body contacting an outer surface of said front wall, and where said outwardly extending portion is positioned between said front wall and said side wall of said electrical box, and said body having a second end extending outwardly from a second side of said front wall.

10. The electrical box assembly of claim 8 , wherein
said body of said cable retainer has a plurality of said arms extending into said cable passage of said body of said cable connector.

11. The electrical box assembly of claim 8 , wherein
said first wall is coupled to said electrical box by a fastener.

12. The electrical box assembly of claim 8 , wherein cable retainer further comprises;
a rear wall and a connecting wall extending between said front wall and said rear wall to define a housing for said cable retainer, and where said cable retainer is positioned between said front wall and said rear wall.

13. The electrical box assembly of claim 12 , wherein said cable retainer includes a first arm and a second arm spaced from said first arm a distance to slide over said cable in a transverse direction with respect to a longitudinal axis of the cable.

14. The electrical box assembly of claim 13 , wherein
said connecting wall has an opening receiving said cable retainer whereby said cable retainer is movable between a first retracted position and a second position in said passage of said cable retainer.

15. The electrical box assembly of claim 8 , further comprising
a collar extending from said front wall and having a dimension to receive the cable, where said body of said cable retainer is received in said collar.

16. A cable retainer and electrical box assembly comprising:
an electrical box having at least one side wall with a cable opening;
a housing having a front wall with an opening defining a cable passage extending through said front wall, a rear wall spaced from said front wall and having a cable opening aligned with said cable opening in said front wall, and a connecting wall extending between said front wall and rear wall; and
a cable retainer having a substantially annular body received in said front wall of said housing and having a cable passage aligned with said cable passage of said housing, said body having a first end received in said opening in said front wall and a second end extending from a second side of said front wall, said cable retainer having at least one spring biased arm extending into said cable passage of said cable retainer for gripping and securing the cable, and where said housing and cable retainer are positioned entirely within a cavity of said electrical box.

17. The cable retainer of claim 16 , wherein
said body has a plurality of said arms extending into said passage toward a second end of said body.

18. The cable retainer of claim 17 , wherein
said first end of said body has an outwardly extending portion oriented for contacting an outer surface of said front wall and capturing said outwardly extending portion between said front wall and said side wall of said electrical box for preventing axial movement of said cable retainer within said opening in said front wall.

19. The cable retainer of claim 17 , wherein
said opening in said front wall has a dimension to receive the cable retainer, said passage in said cable retainer has a dimension to receive an armor sheathing of the cable, and said opening in said rear wall has a dimension to prevent the armor sheathing from passing through.

20. The cable retainer of claim 16 , wherein
said housing is coupled to the electrical box by a screw.
