Abstract

An electrical connector including a connector housing and a cable clamp for providing strain relief to a cable that includes wires terminated to contacts within the connector housing is disclosed. The cable clamp includes a midpiece, cable retention fingers, and a rotating clamp. The rotating clamp includes cable tightening ramps that have a generally radial wedge shape that apply a force to the cable retention fingers when the rotating clamp is securely assembled to the midpiece, providing strain relief to the cable. The cable retention fingers may be an integral part of the midpiece or may be provided as a part of a separate component.

Claims (28)

1. An electrical connector for terminating wires contained within a cable, comprising:

a housing comprising contacts; and

a cable clamp attached to the housing, the cable clamp comprising:

a midpiece;

a rotating clamp securely assembled to the midpiece; and

cable retention fingers disposed within the rotating clamp;

wherein the rotating clamp is configured to apply a force to the cable retention fingers, the cable retention fingers providing strain relief to the cable to prevent the wires from being physically and electrically disconnected from the contacts under nominal operating conditions, wherein the rotating clamp comprises ramps configured to apply an increasing force to the cable retention fingers as the rotating clamp is rotated upon the midpiece while assembling the rotating clamp to the midpiece.

2. The electrical connector of claim 1 , wherein the ramps are radially shaped wedges disposed within the cable retention clamp.

3. The electrical connector of claim 1 , wherein the cable retention fingers are integrally formed as a part of the midpiece.

4. The electrical connector of claim 3 , wherein two cable retention fingers are integrally formed as a part of the midpiece.

5. The electrical connector of claim 3 , wherein four cable retention fingers are integrally formed as a part of the midpiece.

6. The electrical connector of claim 1 , wherein the cable retention fingers are integrally part of a cable retention component separate from the midpiece.

7. The electrical connector of claim 6 , wherein two cable retention fingers are integrally part of a cable retention component separate from the midpiece.

8. The electrical connector of claim 6 , wherein four cable retention fingers are integrally part of a cable retention component separate from the midpiece.

9. The electrical connector of claim 8 , wherein four cable retention fingers are provided as two pairs of cable retention fingers including a first pair of the four cable retention fingers having a first length, and a second pair of the four cable retention fingers having a second length less than the first length.

10. A cable clamp for providing strain relief to a cable attached to an electrical connector housing, comprising:

a midpiece;

a rotating clamp securely assembled to the midpiece; and

cable retention fingers disposed within the rotating clamp;

wherein the rotating clamp is configured to apply a force to the cable retention fingers, the cable retention fingers providing strain relief to the cable to prevent the wires from being physically and electrically disconnected from the contacts under nominal operating conditions, wherein the rotating clamp comprises ramps configured to apply an increasing force to the cable retention fingers as the rotating clamp is rotated upon the midpiece while assembling the rotating clamp to the midpiece.

11. The cable clamp of claim 10 , wherein the ramps are radially shaped wedges disposed within the cable retention clamp.

12. The cable clamp of claim 10 , wherein the cable retention fingers are integrally formed as a part of the midpiece.

13. The cable clamp of claim 12 , wherein two cable retention fingers are integrally formed as a part of the midpiece.

14. The cable clamp of claim 12 , wherein four cable retention fingers are integrally formed as a part of the midpiece.

15. The cable clamp of claim 10 , wherein the cable retention fingers are integrally part of a cable retention component separate from the midpiece.

16. The cable clamp of claim 15 , wherein two cable retention fingers are integrally part of a cable retention component separate from the midpiece.

17. The cable clamp of claim 15 , wherein four cable retention fingers are integrally part of a cable retention component separate from the midpiece.

18. The cable clamp of claim 17 , wherein four cable retention fingers are provided as two pairs of cable retention fingers including a first pair of the four cable retention fingers having a first length, and a second pair of the four cable retention fingers having a second length less than the first length.
