Abstract

A protective device for electrical conduits including a body having a lower opening for engaging with a first conduit and a central cavity for receiving conductors extending from the first conduit to a second conduit, a top member having an upper opening for engaging with the second conduit, and a coupler extendable between the body and the top member to close the protective device, wherein the coupler includes an exterior wall with at least one orifice configured for receiving a fastener.

Claims (35)

1. A protective device for electrical conduit systems, comprising:

a body having a lower opening for engaging with a first conduit and a central cavity for receiving conductors extending from the first conduit to a second conduit;

a top member having an upper opening for engaging with the second conduit; and

a coupler engaged around the body and slidable, between an open position distal to the top member and a closed position attached to the top member, to open and close the protective device,

wherein the coupler includes an exterior wall with at least one orifice configured for receiving a fastener.

2. The protective device of claim 1 , wherein the at least one orifice extends through the exterior wall of the coupler substantially perpendicular to an axis of the protective device.

3. The protective device of claim 1 , further comprising the fastener removably engaged in the at least one orifice, a distal end of the fastener positionable against an exterior surface of the body.

4. The protective device of claim 3 , wherein the fastener presses the exterior surface of the body against an interior surface of the coupler on a side of the protective device opposite the fastener.

5. The protective device of claim 1 , wherein the at least one orifice is adjacent to a proximal end of the coupler.

6. The protective device of claim 1 , wherein said body and said top member are spaced apart by a gap providing 360-degree access to the central cavity when said coupler is in the open position.

7. The protective device of claim 1 , further comprising a barrier assembly within the cavity of said body, the barrier assembly at least partially penetrable by the conductors extending from the first conduit to the second conduit.

8. The protective device of claim 7 , wherein the barrier assembly includes at least one brush barrier having an outer rim and a plurality of bristles attached to and extending inwardly from the outer rim, the conductors passing through the bristles.

9. The protective device of claim 7 , wherein the barrier assembly includes two brush barriers each having an outer edge and a plurality of bristles extending inwardly from the outer edge, the conductors passing through the bristles, and a spacer between the two brush barriers.

10. The protective device of claim 7 , wherein the cavity of said body includes a seat receiving the barrier assembly.

11. The protective device of claim 10 , wherein the barrier assembly includes a stop element, wherein said body includes an internal groove receiving the stop element and securing the barrier assembly between the seat and the stop element.

12. The protective device of claim 1 , wherein said coupler is attached to said top member in the closed position via a threaded engagement.

13. The protective device of claim 1 , wherein said body includes a groove on an exterior surface and a snap ring in the groove between said body and said coupler, wherein said coupler includes an upper groove engaging with the snap ring in the open position and a lower groove engaging with the snap ring in the closed position.

14. The protective device of claim 1 , wherein said body includes a groove on an exterior surface and a positioning snap ring removably positionable in the groove below a lower edge of said coupler when said coupler is in the closed position.

15. A method of grounding a protective device in an electrical conduit system, comprising steps of:

securing a body of the protective device to a first conduit, the protective device including the body having a lower opening, an upper opening, and a cavity extending between the lower and upper openings, a top member having an upper opening, and a coupler slidably engaged around the body, the coupler slidable between an open position distal to the top member and a closed position attached to the top member, and the coupler having an orifice extending through an exterior wall of the coupler;

securing the top member of the protective device, via the upper opening of the top member, to a second conduit;

passing a plurality of conductors from the first conduit, through the cavity of the body into the second conduit;

closing the protective device by moving the coupler to the closed position; and

engaging a fastener through the orifice at least until a distal end of the fastener is positioned against the body and an interior surface of the coupler engages against an exterior surface of the body on a side of the protective device opposite the fastener.

16. The method of claim 15 , wherein the orifice extends through the exterior wall of the coupler substantially perpendicular to an axis of the protective device.

17. The method of claim 15 , wherein the orifice is adjacent to a proximal end of the coupler.

18. The method of claim 15 , wherein the protective device further includes a brush barrier within the cavity of the body, the brush barrier including an outer rim and a plurality of bristles attached to and extending inwardly from the outer rim, the conductors passing through the bristles to penetrate the brush barrier.

19. The method of claim 15 , wherein, while securing the body to the first conduit and securing the top member to the second conduit, the coupler is retained in the closed position via a positioning snap ring engaged in a groove on an exterior surface of the body and below a lower edge of the coupler.

20. A protective device for electrical conduit systems, comprising:

a body having a lower opening for engaging with a first conduit and a central cavity for receiving conductors extending from the first conduit to a second conduit;

a top member having an upper opening for engaging with the second conduit;

a coupler slidable between the body and the top member to close the protective device; and

a barrier assembly within the cavity of the body, the barrier assembly at least partially penetrable by the conductors extending from the first conduit to the second conduit,

wherein the coupler includes an exterior wall with at least one orifice configured for receiving a fastener.

21. The protective device of claim 20 , further comprising the fastener removably engaged in the at least one orifice, a distal end of the fastener positionable against an exterior surface of the body, the fastener configured to press the exterior surface of the body against an interior surface of the coupler on a side of the protective device opposite the fastener.
