Coaxial cable connector with friction-fit sleeve
View Patent ↗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.
1. A coaxial cable connector comprising:
a connector body having a rearward sleeve receiving end and an inner sleeve engagement surface; and
an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having first and second annular projections formed on an outer surface thereof for frictionally engaging said inner sleeve engagement surface of said connector body, said first annular projection having a first outer diameter and said second annular projection having a second outer diameter, said second outer diameter being greater than said first outer diameter whereby said second annular projection provides a stronger press-fit holding force in a radial direction against said inner sleeve engagement surface than said first annular projection.
2. A coaxial cable connector comprising:
a connector body having a rearward sleeve receiving end and an inner sleeve engagement surface;
an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having a first and a second annular projections formed on an outer surface thereof for frictionally engaging said inner sleeve engagement surface of said connector body, said first annular projection having a first outer diameter and said second annular projection having a second outer diameter, said second outer diameter being greater than said first outer diameter whereby said second annular projection provides a stronger press-fit holding force in a radial direction against said inner sleeve engagement surface than said first annular projection; 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,
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.
3. A coaxial cable connector as defined in claim 2 wherein said connector body includes a recess formed in said inner surface for lockingly receiving said locking barb.
4. A coaxial cable connector as defined in claim 2 , wherein said connector body is made from a plastic material.
5. A coaxial cable connector as defined in claim 2 , further comprising a nut rotatably coupled to said post.
6. A coaxial cable connector as defined in claim 2 , wherein said sleeve is made from a plastic material.
7. A coaxial cable connector as defined in claim 2 , wherein said locking sleeve further comprises 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.
8. A coaxial cable connector as defined in claim 2 , wherein said first barb of said annular post is formed with a forward facing edge and said locking sleeve further includes an inwardly directed shoulder portion, said shoulder portion having a rearward facing wall being positioned axially forward of said forward facing edge of said first post barb when said sleeve is moved to a forward most locking position in said connector body, thereby forming an annular chamber bounded by said rearward facing wall of said shoulder portion and said forward facing edge of said first post barb for receiving a jacket of a cable inserted in said cable connector, wherein rearward movement of said locking sleeve compresses the cable jacket against said forward facing edge of said first post barb.
9. A coaxial cable connector as defined in claim 8 , wherein said shoulder portion of said sleeve is axially positioned between said first and second post barbs when said sleeve is moved to said forward most locking position.
10. A coaxial cable connector comprising:
a connector body having a rearward sleeve receiving end and an inner sleeve engagement surface;
an axially movable locking sleeve seated in said rearward sleeve receiving end of said connector body, said locking sleeve having a first and a second annular projections formed on an outer surface thereof for frictionally engaging said inner sleeve engagement surface of said connector body, said first annular projection having a first outer diameter and said second annular projection having a second outer diameter, said second outer diameter being greater than said first outer diameter whereby said second annular projection provides a stronger press-fit holding force in a radial direction against said inner sleeve engagement surface than said first annular projection; 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,
wherein said connector body includes a recess formed in said inner surface for lockingly receiving said locking barb.
11. A coaxial cable connector as defined in claim 10 , wherein said connector body is made from a plastic material.
12. A coaxial cable connector as defined in claim 10 , further comprising a nut rotatably coupled to said post.
13. A coaxial cable connector as defined in claim 10 , wherein said sleeve is made from a plastic material.
14. A coaxial cable connector as defined in claim 10 , wherein said locking sleeve further comprises 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.
15. A coaxial cable connector as defined in claim 10 , wherein said first barb of said annular post is formed with a forward facing edge and said locking sleeve further includes an inwardly directed shoulder portion, said shoulder portion having a rearward facing wall being positioned axially forward of said forward facing edge of said first post barb when said sleeve is moved to a forward most locking position in said connector body, thereby forming an annular chamber bounded by said rearward facing wall of said shoulder portion and said forward facing edge of said first post barb for receiving a jacket of a cable inserted in said cable connector, wherein rearward movement of said locking sleeve compresses the cable jacket against said forward facing edge of said first post barb.
16. A coaxial cable connector as defined in claim 15 , 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.
