Abstract

A connector is provided for terminating coaxial cable. The connector includes a connector body having a cable receiving end and an opposed connection end. A locking sleeve is provided in detachable, re-attachable snap engagement with the insertion end of the connector body for securing the cable in the connector body. The cable may be terminated to the connector by inserting the cable into the locking sleeve or the locking sleeve may be detachably removed from the connector body and the cable inserted directly into the cable body with the locking sleeve detached subsequently.

Claims

1. A connector for terminating an end of a coaxial cable comprising:

a connector body having a cable receiving end for accommodating said end of said cable; and

a locking sleeve coupled to said cable receiving end of said body and being detachable and reattachable thereto to define an attached position and a detached position, said locking sleeve adapted to receive said cable end in either of said attached or detached positions and being movable with respect to said connector body for locking said cable to said connector body;

wherein said connector body and said locking sleeve include cooperative detent structure for permitting said detachment and reattachment of said connector body and said locking sleeve, said cooperative detent structure including;

said connector body having a rib; and

said locking sleeve including an annular groove defined between a pair of spaced apart sleeve rings;

said rib being resident within said groove in a first position; and

wherein said sleeve rings include a forward sleeve ring and a rearward sleeve ring, said forward sleeve ring including a rearwardly directed chamfered wall to permit resilient detachment of said locking sleeve from said body.

2. A connector of claim 1 wherein said locking sleeve includes at least one slot formed at least partially through a forward end thereof, said slot facilitating said resilient detachment of said sleeve from said body.

3. A connector of claim 1 wherein said forward end of said sleeve includes a plurality of circumferentially spaced slots formed at least partially through a forward end thereof, said slots facilitating said resilient detachment of said sleeve from said body.

4. A connector of claim 1 wherein said locking sleeve is made of a plastic material, said detachable and reattachable attachment of said locking sleeve to said cable receiving end of said body being facilitated by resiliency of said plastic material.

5. A connector of claim 1 wherein said locking sleeve has a forward end attachable to said connector body and said annular groove is provided at the locking sleeve forward end.

6. A connector of claim 1 wherein said locking sleeve is movable with respect to said body from a first position retaining said cable end to a second position locking said cable to said cable body.

7. A connector of claim 5 wherein said locking sleeve is coupled to said body in said second position.

8. A connector of claim 1 wherein said rearward sleeve ring includes a forwardly directed chamfered wall to facilitate axial movement of said locking sleeve.

9. A connector of claim 8 wherein said locking sleeve includes a radially outwardly directed end ring adjacent said cable receiving end thereof.

10. A connector of claim 9 wherein said end ring is engageable with said body rib of said connector body upon said axial movement to define said second position.

11. A coaxial cable connector comprising:

a connector body having a receiving end; and

a locking sleeve formed of resilient plastic and attachably coupled to said connector body receiving end, said locking sleeve having a rearward end through which an end of a prepared coaxial cable may be inserted and a forward end defining a forward peripheral edge opposite said rearward end, said forward end being insertable into said receiving end of said connector body and having a radially outwardly directed ring formed at said forward end, said ring cooperating with structure at said connector body receiving end for holding said locking sleeve in said connector body in a first position;

wherein said locking sleeve is detachable and reattachable to said cable receiving end of said body, said detachable and reattachable attachment being facilitated by said resiliency of said plastic material; and

wherein said locking sleeve is movable with respect to said connector body to a second position for locking said cable within said connector.

12. A coaxial cable connector as defined in claim 11 wherein said radially outwardly directed ring forms part of a cooperating detent structure for permitting said locking sleeve to be detached and reattached to said connector body.

13. A coaxial cable connector comprising:

a connector body having a receiving end and an annular rib; and

a locking sleeve formed of resilient plastic and attachably coupled to said connetor body receiving end, said locking sleeve having a rearward end through which an end of a prepared coaxial cable may be inserted and a forward end defining a forward peripheral edge opposite said rearward end, said forward end being insertable into said receiving end of said connector body and having an annular groove defined between first and second spaced apart rings formed at said forward end, said rings cooperating with said annualar rib of said connector body receiving end for holding said locking sleeve in said connector body in a first position;

wherein said locking sleeve is detachable and reattachable to said cable receiving end of said body, said detachable and reattachable attachment being facilitated by said resiliency of said plastic material; and

wherein said ring formed on said forward peripheral edge of said locking sleeve includes a rearwardly directed chamfered wall to permit detachment of said locking sleeve from said body.

14. A coaxial cable connector as defined in claim 13, wherein said second sleeve ring includes a forwardly directed chamfered wall to facilitate axial movement of said locking sleeve from said first position to said second position.

15. A coaxial cable connector for terminating an end of a coaxial cable comprising:

a connector body having a cable receiving end; and

a locking sleeve removably secured to said cable receiving end of said connector body and movable from a first position retaining said cable end to a second position locking said cable to said connector body;

said locking sleeve being optionally attached to or detached from said body prior to inserting said coaxial cable into said cable receiving end for subsequent cable termination within said body;

wherein one of said connector body or said locking sleeve having a rib and the other of said connector body or locking sleeve including a mating groove, said rib being resident within said groove in said first position for permitting said locking sleeve to be removably secured to said connector body.

16. A connector of claim 15 wherein said locking sleeve includes at least one slot formed at least partially through a forward end of said locking sleeve, said slot facilitating said removability of said locking sleeve from said connector body.

17. A connector of claim 15 wherein said locking sleeve is made of a plastic material, the resiliency of said plastic material facilitating the removability of said locking sleeve from said connector body.

18. A cable connector comprising:

a connector body having a retention rib with a first wall and a chamfered second wall axially opposite the first wall;

a locking sleeve having an attachment end that is secured to the connector body and a cable receiving end opposite the attachment end, the locking sleeve including a shipping position and a locked position;

a first annular flange disposed on the attachment end; and

a chamfered second annular flange disposed on the attachment end and axially space.d from the first annular flange such that a groove is formed between the first annular flange and the second annular flange for receiving the retention rib therein and that the chamfer of the second annular flange is complimentary to the chamfer of the second wall for transitioning the locking sleeve from the shipping position to the locked position.
