Abstract

A coaxial cable connector including a connector body having a rearward sleeve receiving end and an inner engagement surface and an axially movable locking sleeve seated in the rearward sleeve receiving end of the connector body is disclosed. The locking sleeve has a rearward cable receiving end and an opposite forward connector insertion end. The forward connector insertion end is formed with at least one flexible finger for gripping a cable inserted in the sleeve when the locking sleeve is moved from a first position to a second position.

Claims

1. A coaxial cable connector comprising:

a connector body having a rearward sleeve receiving end and an inner engagement surface;

an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having a rearward cable receiving end and an opposite forward connector insertion end, said forward connector insertion end being formed with at least one flexible finger for gripping a cable inserted in said sleeve when said locking sleeve is moved from a first position to a second position; and

an annular post disposed within said connector body, said post having a shoulder portion in press-fit engagement with said connector body, a first radially outwardly projecting barb disposed at a rearward end thereof, a second radially outwardly projecting barb disposed forward of said first barb and an annular tubular extension extending between said shoulder portion and said first and second barbs and having a maximum outer diameter, said first and second barbs having an outer diameter greater than the maximum outer diameter of said annular tubular extension.

2. A coaxial cable connector as defined in claim 1, wherein said connector body includes an internal ramp portion formed on said inner engagement surface for deflecting said flexible finger radially inward as said locking sleeve is moved from said first position to said second position.

3. A coaxial cable connector as defined in claim 1, further comprising

a twistlock device rotatably coupled to said connector body.

4. A coaxial cable connector as defined in claim 1, wherein said sleeve is made from a plastic material.

5. A coaxial cable connector as defined in claim 1, wherein said connector body is made from a plastic material.

6. A coaxial cable connector as defined in claim 1, wherein said flexible finger includes a tapered forward end defining a sharp edge to facilitate gripping of the cable.

7. A coaxial cable connector as defined in claim 1, wherein said locking sleeve includes an outer connector body engagement surface cooperating with said inner engagement surface of said connector body to permit said axial movement of said sleeve from said first position, wherein a cable is loosely retained in the connector, to said second position, wherein a cable is secured in the connector.

10. A coaxial cable connector as defined in claim 1, wherein said locking sleeve comprises:

a base having a forward facing abutment surface;

an upper portion having a forward facing surface substantially parallel with said forward facing abutment surface of said base, said flexible finger extending in a forward direction from said forward facing surface of said upper portion; and

a sidewall extending in a forward direction from said forward facing abutment surface and terminating at said upper portion.

11. A coaxial cable connector as defined in claim 10, wherein said locking sleeve further comprises a plurality of said flexible fingers arranged in a ring, said ring having an outer diameter less than an outer diameter of said sidewall.

12. A coaxial cable connector as defined in claim 10, wherein said locking sleeve further comprises a lateral groove formed between said forward facing surface of said upper portion and said flexible finger to enhance flexibility of said finger.

13. A coaxial cable connector as defined in claim 1, wherein said first and second barbs define an annular region therebetween, and wherein said locking sleeve further comprises an inner surface and an inwardly directed shoulder portion provided on said inner surface, said inwardly directed shoulder portion being disposed in said annular region between said first and second barbs when said locking sleeve is in said second position for facilitating compression of the cable.

8. A coaxial cable connector comprising:

a connector body having a rearward sleeve receiving end and an inner engagement surface; and

an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having a rearward cable receiving end and an opposite forward connector insertion end, said forward connector insertion end being formed with at least one flexible finger for gripping a cable inserted in said sleeve when said locking sleeve is moved from a first position to a second position,

wherein said locking sleeve includes a plurality of flexible fingers defining said forward connector insertion end of said sleeve, at least two adjacent fingers being connected by a web.

9. A coaxial cable connector comprising:

a connector body having a rearward sleeve receiving end and an inner engagement surface; and

an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having a rearward cable receiving end and an opposite forward connector insertion end, said forward connector insertion end being formed with at least one flexible finger for gripping a cable inserted in said sleeve when said locking sleeve is moved from a first position to a second position,

wherein said flexible finger includes a lateral groove formed therein to enhance flexibility of said finger.
