Abstract

In one embodiment, the conduit connector can comprise: a body comprising a hollow center capable of receiving a conduit in a receiving end, wherein the hollow center extends from the receiving end to the connecting end; a spring disposed within the hollow center and extending out of the connecting end, wherein the spring comprises engagement tangs extending into the hollow center, toward the connection end, and spring tangs extending past the connection end and spaced apart a distance greater than or equal to an opening diameter in a junction box; and an antishort bush located in the connecting end of the body, retaining the spring in the body.

Claims (41)

1. A conduit connector, comprising:

a body comprising a hollow center capable of receiving a conduit in a receiving end, wherein the hollow center extends from the receiving end to the connecting end;

a spring disposed within the hollow center and extending out of the connecting end, wherein the spring comprises a spring main portion, engagement tangs extending into the hollow center, toward the connection end, and spring tangs extending past the connection end and spaced apart a distance greater than or equal to an opening diameter in a junction box;

wherein the spring main portion is secured inside the body.

2. The conduit connector of claim 1 , wherein each spring tang comprises a center lug extending outward from a spring main portion, away from the spring and toward the receiving end.

3. The conduit connector of claim 1 , wherein a body portion of the spring is located in the body, and wherein the spring further comprises

an outward flare extending from the body portion to the spring main portion, and

an opening in the spring main portion, wherein a protrusion from an antishort bush located in the connecting end of the body extends into the opening.

4. The conduit connector of claim 1 , wherein each spring tang comprises side lugs angled toward the receiving end at an angle so that, once the connector is attached to an opening, the lugs avoid disengagement after applying a pulling load.

5. The conduit connector of claim 1 , wherein the side lugs form wings on opposite sides of each spring tang and have a shape that diverges from near an end of the spring tang toward the receiving end.

6. The conduit connector of claim 1 , wherein a spring main portion can have three sides, with the spring tangs extending from two opposite sides, and the engagement tangs extend into the channel from all three sides.

7. The conduit connector of claim 1 , wherein the antishort bush further comprises a restrictor extending toward the receiving end, wherein the restrictor restricts movement of the spring.

8. The conduit connector of claim 1 , wherein the antishort bush comprises projections that extend toward the body and through an opening such that a foot on the projection snapfits the antishort bush onto the body.

9. The conduit connector of claim 1 , wherein, near the receiving end, the body comprises a slot such that a corner at the receiving end of the spring passes through the slot and a window near the corner engages a jut on the body.

10. A conduit connector, comprising:

a body comprising a hollow center capable of receiving a conduit in a receiving end and a knob, wherein the hollow center extends from the receiving end to the connecting end;

a spring disposed within the hollow center and extending out of the connecting end, wherein the spring comprises

engagement tangs extend into the hollow center, toward the connection end, wherein the engagement tangs form a generally V-shaped profile that is configured to align a conduit in the channel,

spring tangs comprise a center lug extending outward from a spring main portion, away from the spring and toward the receiving end, wherein the spring tangs extend past the connection end and spaced apart a distance greater than or equal to an opening diameter in a junction box, and wherein each spring tang comprises side lugs angled toward the receiving end at an angle so that, once the connector is attached to an opening, the lugs avoid disengagement after applying a pulling load;

wherein the spring main portion is secured inside the body.

11. The conduit connector of claim 10 , wherein the side lugs form wings on opposite sides of each spring tang and have a shape that diverges from near an end of the spring tang toward the receiving end.

12. The conduit connector of claim 10 , wherein a spring main portion can have three sides, with the spring tangs extending from two opposite sides, and the engagement tangs extend into the channel from all three sides.

13. The conduit connector of claim 11 , wherein the engagement tangs comprise a central receiving tang that is angled from the sides into the channel and having a generally V-shaped end, and a first side receiving tang having a diagonal ends that angles toward the central receiving tang and a second side receiving tang having a diagonal end angled toward the central receiving tang forming a generally V-shaped profile of the engagement tangs.

14. The conduit connector of claim 11 , wherein each engagement tang extends into the body at a different distance than another engagement tang.

15. The conduit connector of claim 10 , wherein antishort bush further comprises a restrictor extending toward the receiving end, wherein the restrictor restricts movement of the spring, and comprises projections that extend toward the body and through an opening such that a foot on the projection snapfits the antishort bush onto the body.

16. The conduit connector of claim 10 , wherein, near the receiving end, the body comprises a slot such that a corner at the receiving end of the spring passes through the slot and a window near the corner engages a jut on the body.

17. A conduit connector, comprising:

a body comprising a stop protrusion near a connecting end and a hollow center capable of receiving a conduit in a receiving end, wherein the hollow center extends from a receiving end to the connecting end, wherein the body has a size that is smaller than a junction box knockout diameter, and wherein the stop protrusion is configured to not allow the entire conduit connector to pass through the junction box knockout;

a spring disposed within the hollow center and extending out of the connecting end, wherein the spring comprises

a main portion;

engagement tangs extend into the hollow center, toward the connection end,

spring tangs comprise a center lug extending outward from a spring main portion, away from the spring and toward the connecting end, wherein the spring tangs extend past the connection end and spaced apart a distance greater than or equal to an opening diameter in a junction box, and wherein each spring tang comprises side lugs angled toward the receiving end at an angle so that, once the connector is attached to an opening, the lugs avoid disengagement after applying a pulling load;

wherein the spring main portion is secured inside the body.

18. A method for installing a conduit connector in a junction box, comprising:

inserting a conduit through a knockout into a junction box;

inserting an end of the conduit that has been passed into the junction box, into the receiving end of a body of the conduit connector up to a conduit stop and engaging the conduit with engagement tangs; and

passing a main body portion of the body from inside the junction box out through the knockout until a stop protrusion on the body contacts an inner surface of the junction box and/or spring tangs extending from a connecting end of the body engage the knockout.

19. The conduit connector of claim 1 , wherein the spring is secured inside the body with a projection that extends from the body to snap the spring into place.

20. The conduit connector of claim 1 , wherein the spring is secured inside the body with a guide channel that extends along the inside of the body for receiving edges of the spring.

21. The conduit connector of claim 1 , wherein the spring is secured inside the body with using a body taper on the body that is engaged in a spring taper slot.

22. The conduit connector of claim 1 , wherein the spring is secured inside the body with an angular channel formed between a tongue and a side of the body, extending along the length of the body, and wherein the spring has a channel slot that receives the tongue.
