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 configured to terminate an end of a coaxial cable, the connector comprising:

a connector body having a cable receiving end, the cable receiving end configured to accommodate said end of said coaxial cable; and

a locking sleeve configured to couple to said cable receiving end of said connector body and configured to detach to define a detached position and to attach thereto to define an attached position,

said locking sleeve configured to insertably receive said end of said coaxial cable therethrough in both of said attached and detached positions and configured to slide in a longitudinal direction with respect to said connector body from a first position to a second position, the second position configured to inseparably lock said coaxial cable to said connector body,

wherein the locking sleeve has a connector body engagement end;

wherein a portion of the connector body engagement end of the locking sleeve is configured to cooperative interact with an inner surface of the connector body proximate the cable receiving end in both the first position and the second position;

wherein said connector body includes an inwardly directed rib adjacent the cable receiving end thereof and wherein said locking sleeve includes a receiving area proximate the connector body engagement end, the receiving area configured to accommodate said inwardly directed rib in said first position, wherein the receiving area is an opening formed between two annular ring surfaces of the locking sleeve proximate the connector body engagement end;

wherein the receiving area is configured to engage the inwardly directed rib to resist forward longitudinal sliding movement of the locking sleeve from the first position.

2. The connector of claim 1, wherein said receiving area of said locking sleeve is defined by at least one wall.

3. The connector of claim 1, wherein the inwardly directed rib of the connector body is adjacent a first portion of the connector body having an inner diameter greater than an inner diameter of a second portion of the connector body, the connector body further comprises an angled interior portion extending between the first and second portions.

4. The connector of claim 1, further comprising a post disposed within the connector body having a barb.

5. The connector of claim 1, wherein the connector body engagement end of the locking sleeve is insertable within the cable receiving end of the connector body.

6. A connector configured to terminate an end of a coaxial cable, the connector comprising:

a connector body comprising an inwardly directed rib and a cable receiving end, the cable receiving end is configured to receive the end of the coaxial cable and the inwardly directed rib is adjacent the cable receiving end; and

a locking sleeve comprising a connector body engagement end and a receiving area proximate to the connector body engagement end, the locking sleeve configured to couple to the cable receiving end of the connector body, to detach defining a detached position and to attach defining an attached position,

wherein the locking sleeve is configured to insertably receive the end of the coaxial cable in the detached position, to attach to the connector body when the connector body has received the coaxial cable, and to slide in a longitudinal direction with respect to the connector body from a first position to a second position, the second position configured to inseparably lock the coaxial cable to the connector body,

wherein the locking sleeve is configured to cooperatively interact with an inner surface of the connector body proximate the cable receiving end in both the first position and the second position,

wherein the receiving area is configured to accommodate the inwardly directed rib in the first position, and

wherein the receiving area is configured to engage the inwardly directed rib to resist forward longitudinal sliding movement of the locking sleeve from the first position.

7. The connector of claim 6, wherein the locking sleeve further comprises two annular ring surfaces defining the receiving area.

8. The connector of claim 7, wherein the two annular ring surfaces comprise a first annular ring surface and a second annular ring surface, the first annular ring surface comprises a chamfered forward first wall and a chamfered rearward second wall opposite the chamfered forward first wall and the second annular ring surface comprises a chamfered forward third wall and a chamfered rearward fourth wall opposite the chamfered forward third wall.

9. The connector of claim 7, wherein the inwardly directed rib is loosely retained between the two annular ring surfaces when in the first position.

10. The connector of claim 9, wherein the connector is configured to loosely retain the coaxial cable within the connector when in the first position.

11. The connector of claim 6, wherein the inwardly directed rib comprises a first rib wall adjacent to the cable receiving end and a chamfered second rib wall opposite the first rib wall, the first rib wall being perpendicular to the connector body.

12. The connector of claim 11, wherein the locking sleeve further comprises a third annular ring surface, the third annular ring surface comprises a chamfered first ring wall and a perpendicular second ring wall opposite the chamfered first ring wall, the first rib wall configured to abut the perpendicular second ring when in the second position.

13. The connector of claim 6, wherein the locking sleeve comprises a resilient material.

14. A connector configured to terminate an end of a coaxial cable comprising:

a connector body having a cable receiving end configured to accommodate the end of the coaxial cable; and

a locking sleeve configured to couple to the cable receiving end of the connector body and configured to detach and reattach thereto to define an attached position and a detached position, the locking sleeve configured to receive the end of the coaxial cable in the attached and detached positions and configured to move with respect to the connector body to lock the coaxial cable to the connector body,

wherein the connector body and the locking sleeve include cooperative detent structures configured to enable detachment and reattachment of the connector body and the locking sleeve, the cooperative detent structures including;

one of the connector body or the locking sleeve having a rib; and

the other of the connector body or locking sleeve including an annular groove,

the rib configured to be resident within the annular groove in a first position.

15. The connector of claim 14, wherein the cooperative detent structure of the locking sleeve comprises two annular ring surfaces defining the annular groove.

16. The connector of claim 15, wherein the cooperative detent structure of the connector body comprises the rib.

17. The connector of claim 16, wherein the rib is loosely retained within the annular groove when in the first position.

18. The connector of claim 14, wherein the connector is configured to loosely retain the coaxial cable within the connector when in the first position.

19. The connector of claim 14, wherein the locking sleeve comprises a sealing element configured to engage the connector body when the coaxial cable is locked to the connector body.

20. The connector of claim 19, wherein the sealing element is an O-ring.
