Abstract

A modular plug includes a plug housing, plug contacts held by the plug housing, and a stuffer cap coupled to the plug housing. The stuffer cap includes a cable channel configured to receive a cable therein. The stuffer cap includes an interior side that defines at least a portion of the cable channel. The modular plug includes a strain relief member held by the plug housing. The strain relief member includes a base and a spring beam extending from the base such that the spring beam is cantilevered from the base. The spring beam is configured to engage the cable and thereby pinch the cable between the interior side of the stuffer cap and the spring beam.

First claim

What is claimed is:

1. A modular plug comprising:
a plug housing;
plug contacts held by the plug housing;
a stuffer cap coupled to the plug housing, the stuffer cap comprising a cable channel configured to receive a cable therein, the stuffer cap comprising an interior side that defines at least a portion of the cable channel; and
a strain relief member held by the plug housing, the strain relief member comprising a base and a spring beam extending from the base such that the spring beam is cantilevered from the base, wherein the spring beam is configured to engage the cable and thereby pinch the cable between the interior side of the stuffer cap and the spring beam, wherein the strain relief member is integrally formed with at least one of the plug contacts.

2. The modular plug of claim 1 , wherein the spring beam is configured to be deflected in a direction generally toward a base of the plug housing as the spring beam is engaged with the cable.

3. The modular plug of claim 1 , wherein the spring beam is a first spring beam, the strain relief member further comprising a second spring beam cantilevered from the base of the strain relief member such that the first and second spring beams oppose each other.

4. The modular plug of claim 1 , wherein the stuffer cap is pivotally coupled to the plug housing such that the stuffer cap is configured to press wires of the cable into electrical contact with the plug contacts when the stuffer cap is pivoted to a closed position, the stuffer cap comprising a slot that extends through the stuffer cap into the cable channel, the slot being configured to receive the spring beam of the strain relief member therein as the stuffer cap is pivoted to the closed position such that the spring beam extends into the slot and into engagement with the cable.

5. The modular plug of claim 1 , further comprising a leadframe that includes a group of the plug contacts that are electrically commoned with each other by a commoning pad, the strain relief member extending outward from the commoning pad.

6. The modular plug of claim 1 , further comprising a leadframe that includes a group of the plug contacts that are electrically commoned with each other, the strain relief member being integrally formed with the leadframe.

7. The modular plug of claim 1 , wherein the plug housing extends from a mating end to a cable end, the spring beam being configured to be deflected in a direction generally toward the mating end of the plug housing as the spring beam is engaged with the cable.

8. The modular plug of claim 1 , wherein the plug is configured to mate with a modular jack along a connection axis, the plug housing extending from a mating end to a cable end, the spring beam being angled relative to the connection axis in a direction generally toward the mating end of the plug housing.

9. The modular plug of claim 1 , wherein the plug housing and the plug contacts are shaped and positioned to define an RJ-45 modular plug mating interface.

10. A modular plug comprising:
a plug housing;
plug contacts held by the plug housing;
a strain relief member held by the plug housing, the strain relief member comprising a base and a spring beam cantilevered from the base, wherein the strain relief member is integrally formed with at least one of the plug contacts; and
a stuffer cap pivotally coupled to the plug housing, the stuffer cap comprising a cable channel configured to receive a cable therein, the stuffer cap comprising an interior side that defines at least a portion of the cable channel, the stuffer cap being configured to press wires of the cable into electrical contact with the plug contacts when the stuffer cap is pivoted to a closed position, the stuffer cap comprising a slot that extends through the stuffer cap into the cable channel, the slot being configured to receive the spring beam of the strain relief member therein as the stuffer cap is pivoted to the closed position such that the spring beam pinches the cable between the interior wall of the stuffer cap and the spring beam.

11. The modular plug of claim 10 , wherein the spring beam is configured to be deflected in a direction generally toward a base of the plug housing as the spring beam pinches the cable.

12. The modular plug of claim 10 , wherein the spring beam is a first spring beam, the strain relief member further comprising a second spring beam cantilevered from the base of the strain relief member such that the first and second spring beams oppose each other.

13. The modular plug of claim 10 , further comprising a leadframe that includes a group of the plug contacts that are electrically commoned with each other by a commoning pad, the strain relief member extending outward from the commoning pad.

14. The modular plug of claim 10 , further comprising a leadframe that includes a group of the plug contacts that are electrically commoned with each other, the strain relief member being integrally formed with the leadframe.

15. The modular plug of claim 10 , wherein the plug housing extends from a mating end to a cable end, the spring beam being configured to be deflected in a direction generally toward the mating end of the plug housing as the spring beam pinches the cable.

16. The modular plug of claim 10 , wherein the plug is configured to mate with a modular jack along a connection axis, the plug housing extending from a mating end to a cable end, the spring beam being angled relative to the connection axis in a direction generally toward the mating end of the plug housing.

17. The modular plug of claim 10 , wherein the plug housing and the plug contacts are shaped and positioned to define an RJ-45 modular plug mating interface.

18. A modular plug comprising:
a cable having an insulative cable jacket and an end;
a plug housing;
plug contacts held by the plug housing;
a stuffer cap coupled to the plug housing, the stuffer cap comprising a cable channel and an interior side that defines at least a portion of the cable channel, the end of the cable being received within the cable channel; and
a strain relief member held by the plug housing, the strain relief member comprising a base and a spring beam cantilevered from the base, wherein the spring beam is engaged with the insulative jacket of the cable such that the cable is pinched between the interior side of the stuffer cap and the spring beam, wherein the strain relief member is integrally formed with at least one of the plug contacts.

19. The modular plug of claim 18 , wherein the spring beam is a first spring beam, the strain relief member further comprising a second spring beam cantilevered from the base of the strain relief member such that the first and second spring beams oppose each other.
