Abstract

A patch cord including a connector attached to an end of an electrical cable. The connector includes a boot member that slides over a portion of a wire manager to actuate a retention arrangement of the connector. Certain types of retention arrangements are actuated by deflecting flexible tabs of the wire manager inwardly to bite into at least an outer jacket of the electrical cable.

First claim

What is claimed is:

1. A patch cord comprising:
a cable including twisted pairs surrounded by insulating layer; and
a connector attached to one end of the cable, the connector including:
a plug body;
a sleeve disposed around the cable, the sleeve defining a first through-passage, the sleeve including at least one flexible tab having a tooth that extends into the first through-passage when the at least one flexible tab is undeflected, the flexible tab facing towards the cable; and
a boot member defining a passage through which the cable extends, the passage being sized to press the flexible tab towards the cable to enable the boot member to fit over the sleeve, wherein the tooth bites into the insulating layer of the cable without disturbing the twisted pairs when the flexible tab is pressed towards the cable by the boot member.

2. The patch cord of claim 1 , wherein the insulating layer also includes an inner jacket; and wherein the tooth of the flexible tab also bites at least partially into an inner jacket of the cable.

3. The patch cord of claim 1 , wherein the at least one flexible tab extends towards the plug body.

4. The patch cord of claim 1 , wherein the sleeve includes a second flexible tab located at an opposite side of the sleeve from the at least one flexible tab.

5. The patch cord of claim 1 , wherein the cable initially deflects the at least one flexible tab outwardly from the first through-passage until the boot member is disposed around the sleeve.

6. The patch cord of claim 1 , wherein the sleeve includes a wire manager.

7. The patch cord of claim 1 , further comprising a second connector attached to an opposite end of the cable, the second connector including:
a second plug body;
a second sleeve disposed around the cable, the second sleeve including at least one flexible tab having a tooth that faces towards the cable; and
a second boot member defining a passage through which the cable extends, the passage being sized to press the flexible tab of the second sleeve towards the cable to enable the second boot member to fit over the second sleeve, wherein the tooth of the second sleeve bites into the outer jacket of the cable when the flexible tab is pressed towards the cable by the second boot member.

8. The patch cord of claim 7 , wherein the second connector is identical to the connector.

9. An electrical connector comprising:
a plug body;
a sleeve extends from a wire manager defining a plurality of channels, the wire manager being configured to couple to the plug body, the sleeve defining a first through-passage, the sleeve including at least one flexible tab having a tooth that extends into the first through-passage when the at least one flexible tab is undeflected; and
a boot member configured to slide over the sleeve during assembly of the electrical connector, the boot member defining a second through-passage sized to press the at least one flexible tab towards the first through-passage when the boot member slides over the wire manager, the boot member inhibiting outward deflection of the at least one flexible tab when the boot member is disposed around the sleeve, wherein the sleeve and boot member are sized so that the sleeve is wholly retained within the boot member when the electrical connector is assembled.

10. The electrical connector of claim 9 , wherein the wire manager includes a second flexible tab located at an opposite side of the wire manager from the at least one flexible tab.

11. The electrical connector of claim 9 , wherein the at least one flexible tab extends towards the plug body.

12. The electrical connector of claim 9 , wherein the wire manager includes latch members that extend towards the boot member and the boot member defines latching openings sized to receive hooks of the latch members.

13. The electrical connector of claim 12 , wherein the wire manager is configured to snap-fit to the plug body.

14. A method of providing strain relief to a cable connector that terminates a cable having an outer jacket, the method comprising:
a) threading a first end of the cable through a boot member;
b) threading the first end of the cable through a through-passage defined in a sleeve and deflecting teeth of flexible tabs of the sleeve out of the through-passage, the teeth extending into the through-passage when the flexible tabs are undeflected;
c) separating out twisted pairs of the cable at a plurality of channels at the sleeve;
d) terminating the first end of the cable at a plug body and coupling the plug body to the sleeve; and
e) sliding the boot member over the sleeve to deflect the distal ends of the flexible tabs back into the passage to bite into the outer jacket of the cable.

15. The method of claim 14 , further comprising coupling the boot member to the sleeve.

16. The method of claim 14 , wherein deflecting the teeth of the flexible tabs back into the passage causes the teeth to bite into an inner jacket of the cable.

17. The method of claim 14 , further comprising performing steps (a)-(d) at a second end of the cable.

18. The method of claim 14 , wherein coupling the boot member to the sleeve comprises latching the boot member to a wire manager that extends forwardly of the sleeve.

19. The method of claim 17 , further comprising organizing conductors of the cable at the wire manager for insertion into the plug body.
