Abstract

A coaxial cable connector includes an annular post defining an axial bore therein, a cylindrical connector body coupled to the post, a nut rotatably coupled to the post and a sleeve movably connected to the connector body. The sleeve includes at least one radially outwardly extending ridge formed on an outer surface thereof, which frictionally engages an inner surface of the connector body. As a result, the inner surface of the connector body does not require a recess or other engagement structure formed thereon.

Claims

1. A coaxial cable connector comprising:

a connector body made from a plastic material and having a sleeve receiving end defining an inner engagement surface; and

a locking sleeve having at least one projection formed on an outer surface thereof for frictionally engaging said inner engagement surface of said connector body when said locking sleeve is moved from a first position to a second position.

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

an annular post disposed within said connector body; and

a nut rotatably coupled to said post.

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

4. A coaxial cable connector as defined in claim 1, wherein said locking sleeve includes 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.

5. A coaxial cable connector as defined in claim 1, wherein said locking sleeve includes a forward projection defining a first sleeve diameter and a rearward projection defining a second sleeve diameter, said second sleeve diameter being larger than said first sleeve diameter.

6. A coaxial cable connector comprising:

a connector body having a rearward sleeve receiving end;

an annular post disposed within said connector body, said post having a radially outwardly projecting barb disposed at a rearward end thereof; and

an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having an inwardly directed shoulder portion, said shoulder portion being positioned axially forward of said post barb when said sleeve is moved to a forward most locking position in said connector body.

7. A coaxial cable connector as defined in claim 6, wherein an annular chamber is formed between said post barb and said inwardly directed shoulder portion of said sleeve, said annular chamber having a forward boundary defined by said sleeve shoulder portion and a rearward boundary defined by said post barb.

8. A coaxial cable connector as defined in claim 6, wherein said post further includes a second radially outwardly projecting barb disposed forward of said first barb, said shoulder portion of said sleeve being axially positioned between said first and second post barbs when said sleeve is moved to said forward most locking position.

9. A coaxial cable connector as defined in claim 6, wherein said post further includes a flanged base portion disposed at a forward end thereof and a radially outwardly protruding connector body locking barb disposed between said forward base portion and said rearward end barb, said locking barb engaging an inner surface of said connector body to secure said post to said body.

10. A coaxial cable connector as defined in claim 9, wherein said connector body includes a recess formed in said inner surface for lockingly receiving said locking barb.

11. A coaxial cable connector comprising:

a connector body having a rearward sleeve receiving end;

an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body; and

an annular post disposed within said connector body, said post having a first radially outwardly projecting barb disposed at a rearward end thereof and a second radially outwardly projecting barb disposed forward of said first barb.

12. A coaxial cable connector as defined in claim 11, wherein said post further includes a flanged base portion disposed at a forward end thereof and a radially outwardly protruding connector body locking barb disposed between said forward base portion and said rearward end barb, said locking barb engaging an inner surface of said connector body to secure said post to said body.

13. A coaxial cable connector as defined in claim 12 wherein said connector body includes a recess formed in said inner surface for lockingly receiving said locking barb.

14. A coaxial cable connector comprising:

a connector body having a rearward sleeve receiving end;

an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body; and

an annular post disposed within said connector body, said post having a radially outwardly projecting barb disposed at a rearward end thereof, a flanged base portion disposed at a forward end thereof and a radially outwardly protruding connector body locking barb disposed between said forward base portion and said rearward end barb, said locking barb engaging an inner surface of said connector body to secure said post to said body.

15. A coaxial cable connector as defined in claim 14, wherein said connector body includes a recess formed in said inner surface for lockingly receiving said locking barb.
