Abstract

A manufacturer installed cable clamping insert is provided that can be used to fix various sizes of non-metallic sheeted cables to an electrical outlet box. The insert can be oval in shape and can be used to secure the cable without a tool. In use, the cable is simply pushed through a flap of the insert to a desired position in the enclosure. The cables can be removed or readjusted simply by lifting the flap from inside of the enclosure.

First claim

What is claimed is:

1. An enclosure assembly, comprising:
an enclosure having a rear surface and an enclosure opening defined through at least one wall;
a cable clamping insert having an internal portion separated from an external portion by a ring stop and a cable passing opening defined therethrough, the internal portion having one or more upper retaining clips and one or more lower retaining clips, the upper and lower retaining clips having a cam surface and a locking surface, the cable clamping insert being disposed in the enclosure opening with the one or more retaining clips proximate the rear surface so that the wall of the enclosure is disposed in a slot defined between the locking surfaces and the ring stop, the external portion having a living hinge resiliently securing a flap thereto so that the flap normally closes the cable passing opening.

2. The enclosure assembly of claim 1 , wherein the enclosure opening and the cable clamping insert are oval having a minor axis and a major axis.

3. The enclosure assembly of claim 2 , wherein the one or more upper retaining clips comprises two upper retaining clips.

4. The enclosure assembly of claim 3 , wherein the one or more lower retaining clips comprises one lower retaining clip.

5. The enclosure assembly of claim 4 , wherein each of the two upper retaining clips partially circumvent the major axis and partially circumvent the minor axis, and wherein the one retaining clip partially circumvents the major axis along both sides and completely circumvents the minor axis.

6. The enclosure assembly of claim 5 , wherein the lower retaining clip comprises a relief in the cam surface along the minor axis.

7. The enclosure assembly of claim 1 , wherein the one or more lower retaining clips are longer than the one or more upper retaining clips.

8. The enclosure assembly of claim 1 , further comprising lateral extensions defined on the flap extending towards the external portion.

9. The enclosure assembly of claim 8 , wherein the lateral extensions further comprise curved end regions defining an area of reduced cross section.

10. The enclosure assembly of claim 1 , further comprising one or more fastener retainers configured retain a portion of an enclosure fastener.

11. The enclosure assembly of claim 10 , wherein the one or more fastener retainers are configured to resiliently retain the enclosure fastener against the enclosure.

12. The enclosure assembly of claim 10 , wherein the one or more fastener retainers further comprise a plurality of protrusions formed in series.

13. The enclosure assembly of claim 10 , wherein the one or more fastener retainers further comprise a terminal end having a retainer capturing hook or curve.

14. A cable clamping insert, comprising:
an internal portion having one or more upper retaining clips and one or more lower retaining clips, the upper and lower retaining clips having a cam surface and a locking surface;
an external portion having a living hinge resiliently securing a flap thereto;
a ring stop separating the internal and external portions, a slot defined between the locking surfaces and the ring stop; and
a cable passing opening defined through the internal portion, the external portion, and the ring stop.

15. The insert of claim 14 , wherein the internal portion, the external portion, and the ring stop are oval having a minor axis and a major axis.

16. The insert of claim 15 , wherein the one or more upper retaining clips comprises two upper retaining clips.

17. The insert of claim 16 , wherein the one or more lower retaining clips comprises one lower retaining clip.

18. The insert of claim 17 , wherein each of the two upper retaining clips partially circumvent the major axis and partially circumvent the minor axis, and wherein the one lower retaining clip partially circumvents the major axis along both sides and completely circumvents the minor axis.

19. The insert of claim 18 , wherein the lower retaining clip comprises a relief in the cam surface along the minor axis.

20. The insert of claim 14 , further comprising lateral extensions defined on the flap extending towards the external portion.

21. The enclosure assembly of claim 20 , wherein the lateral extensions further comprise curved end regions defining an area of reduced cross section.
