Connector with cable retention feature and patch cord having the same

1. A patch cord comprising:

a) a cable having a first end and a second end, the cable including:

i) a plurality of twisted conductor pairs;

ii) an inner jacket surrounding the plurality of twisted conductor pairs; and

iii) an outer jacket surrounding the inner jacket; and

b) a connector attached to one of the first and second ends of the cable, the connector including:

i) a plug nose including contacts configured to terminate the twisted conductor pairs; and

ii) a single-piece attachment member having a management section, a boot, and a collar, the management section defining channels configured to receive the twisted conductor pairs of the cable, the boot providing strain relief to the cable, and the collar including a retention arrangement including at least one rigid tooth that protrudes inwardly to bite into the outer jacket of the cable.

2. The patchcord of claim 1 , wherein the attachment member of the connector also includes a retention section including a base and a moveable cover that is configured to clamp the inner jacket of the cable therebetween.

3. The patchcord of claim 1 , wherein the collar includes four inwardly protruding teeth spaced at regular intervals around an interior surface of the collar.

4. The patchcord of claim 1 , wherein the collar defines a ledge at a transition from a first section of the collar to a second section of the collar, the first section having a smaller internal diameter than the second section.

5. The patchcord of claim 4 , wherein the internal diameter of the second section is sufficiently large to accommodate the outer jacket of the cable and the internal diameter of the first section is not sufficiently large to accommodate the outer jacket.

6. The patchcord of claim 4 , wherein the outer jacket of the cable abuts against the ledge.

7. A method of assembling a patch cord, the method comprising:

a) providing a cable including a plurality of twisted pairs and a double layer jacket surrounding the twisted pairs, wherein an outer layer of the double layer jacket has been removed from a section of the cable and an inner layer of the double layer jacket has been removed from a portion of the section of the cable;

b) sliding an attachment member axially over the cable until the twisted pairs slide into a management section, the inner jacket slides into a retention section, and the outer jacket slides into a collar, over a plurality of rigid teeth, and against a ledge;

c) closing a cover to clamp around the inner jacket of the cable; and

d) sliding a plug nose over the cable towards the attachment member until the plug nose latches to the attachment member.

8. A connector comprising a single-piece attachment member defining a passage therethrough, the attachment member having a management section, a boot, and a collar, the management section defining a plurality of channels, the boot configured to provide cable strain relief, and the collar including a retention arrangement including opposing rigid teeth that protrude radially inwardly, each of the rigid teeth ramping away from the management section and defining a shoulder facing away from the management section.

9. The connector of claim 8 , further comprising a plug nose that is coupled to the attachment member.

10. The connector of claim 9 , wherein the plug nose extends over the management section of the attachment member.

11. The connector of claim 8 , wherein the collar includes four inwardly protruding teeth spaced at regular intervals around an interior surface of the collar.

12. A connector comprising:

a plug nose including a plurality of electrical contacts; and

an attachment member that is configured to couple to the plug nose, the attachment member extending along an axis from a first end to a second end, the attachment member defining a through-passage extending along the axis, the attachment member defining a plurality of channels at the first end and defining a ring at the second end, the attachment member also including a plurality of teeth extending inwardly from an inner surface of the ring, each of the teeth ramping inwardly as the tooth extends towards the first end of the attachment member so that each tooth defines an inwardly facing edge.

13. The connector of claim 12 , wherein the plug nose latches to the attachment member.

14. The connector of claim 12 , wherein the attachment member includes four teeth extending inwardly from an inner surface of the ring.
