Abstract

In an embodiment, a coaxial quick connector assembly comprises an inner connector body having a first end for coupling with a coaxial cable and a second end having a perimeter contact for engagement with an externally threaded coaxial coupling. The perimeter contact includes a wall defining a central passageway. The perimeter wall includes at least one protrusion projecting toward the central passageway. An outer connector body is in mechanical communication with the inner connector body such that when the perimeter contact is engaged with the externally threaded coaxial coupling and the outer connector body is moved to an engaged position, an interior surface of the outer connector impinges the at least one protrusion between the interior surface of the outer connector body and the external surface of the externally threaded coaxial coupling, such that the assembly is held in place with respect to the threaded coaxial coupling.

Claims

1. A coaxial quick connector assembly comprising:

an inner connector body having a first end adapted to couple with a coaxial cable and a second end having a perimeter contact adapted to releasably engage with an external surface of an externally threaded coaxial coupling;

the perimeter contact in electrical communication with a conductive layer of the coaxial cable and including at least one perimeter wall defining a central passageway at least partially surrounding a coaxial center wire, the at least one perimeter wall having at least one protrusion projecting toward the central passageway;

an outer connector body in mechanical communication with the inner connector body and positionable between an engaged position and a disengaged position;

wherein when the perimeter contact is engaged with the externally threaded coaxial coupling and the outer connector body is moved to the engaged position, an interior surface of the outer connector body limits movement of the at least one protrusion by impinging the at least one protrusion between the interior surface of the outer connector body and the external surface of the externally threaded coaxial coupling such that the assembly is held in place with respect to the threaded coaxial coupling.

2. The assembly of claim 1, wherein the first end is one of threadably coupled and bonded with the coaxial cable.

3. The assembly of claim 1, wherein the at least one protrusion projects from the perimeter contact toward the central passageway only when the outer connector is moved towards the engaged position.

4. The assembly of claim 1, wherein at least a portion of the at least one protrusion passes through the at least one perimeter wall of the perimeter contact.

5. The assembly of claim 1, wherein at least one protrusion biasing element biases the at least one protrusion towards the central passageway.

6. The assembly of claim 1, wherein at least one outer connector body biasing element biases the outer connector body towards the engaged position.

7. A coaxial quick connector assembly comprising:

an inner connector body having a first end adapted to couple with a coaxial cable and a second end having a perimeter contact adapted to releasably engage with an external surface of an externally threaded coaxial coupling;

the perimeter contact in electrical communication with a conductive layer of the coaxial cable and having at least one perimeter structure defining a central passageway at least partially surrounding a coaxial center wire, the perimeter contact positionable between an engaged position and a disengaged position;

a wedge element in mechanical communication with at least a portion of the perimeter contact such that when the perimeter contact is moved to the disengaged position an interior diameter of the perimeter contact is increasable, and when the perimeter contact is moved to the engaged position an interior diameter of the perimeter contact is decreasable.

8. The assembly of claim 7, wherein the first end is one of threadably coupled and bonded with the coaxial cable.

9. The assembly of claim 7, further comprising an outer connector body in mechanical communication with the perimeter contact, the outer connector body adapted to assist in moving the perimeter contact between the engaged position and the disengaged position.

10. The assembly of claim 7, wherein the perimeter contact comprises a helical coil.

11. The assembly of claim 7, wherein the perimeter contact comprises an expandable cuff.

12. The assembly of claim 7, wherein when the perimeter contact is in the engaged position with respect to the externally threaded coaxial coupling, at least a portion of the perimeter contact is in mechanical communication with the external portion of the externally threaded coaxial coupling such that the assembly is held in place with respect to the threaded coaxial coupling.

13. The assembly of claim 7, wherein the perimeter contact is biased towards the engaged position.

14. The assembly of claim 7, wherein the outer connector body is biased towards the engaged position.

15. The assembly of claim 7, further comprising at least one protrusion projecting from the perimeter contact toward the central passageway, the at least one protrusion adapted to engage the external surface of the threaded coaxial coupling when the perimeter contact is moved towards the engaged position.

16. A method of removably coupling a coaxial quick connector assembly with an externally threaded coaxial coupling comprising:

passing an externally threaded coaxial coupling into a central passageway of the perimeter contact;

engaging an external surface of an externally threaded coaxial coupling with at least one protrusion of the perimeter contact; and

impinging the at least one protrusion between an interior surface of an outer connector body and the external surface of the externally threaded coaxial coupling such that the assembly is held in place with respect to the externally threaded coaxial coupling.

17. The method of claim 16, wherein impinging the at least one protrusion between an interior surface of an outer connector body and the external surface of the externally threaded coaxial coupling further comprises passing the at least one protrusion through a perimeter wall of the perimeter contact.

18. A method of removably coupling a coaxial quick connector assembly with an externally threaded coaxial coupling comprising:

passing an externally threaded coaxial coupling into a central passageway of the perimeter contact;

moving the perimeter contact to an engaged position such that an interior diameter of the perimeter contact is decreased; and

engaging an external portion of the externally threaded coaxial coupling with at least a portion of the perimeter contact such that the assembly is held in place with respect to the threaded coaxial coupling.

19. The method of claim 18, further comprising moving the perimeter contact to a disengaged position before passing an externally threaded coaxial coupling into the central passageway of the perimeter contact.

20. The method of claim 18, wherein moving the perimeter contact to an engaged position comprises biasing the perimeter contact to the engaged position.
