A cord assembly for an electronic device includes a cord having an insulation layer with a first end and an exterior surface, as well as at least one electrical conductor extending within the insulation layer. A strength member also extends within the insulation layer and includes a first end extending beyond the first end of the insulation layer. A securing element couples the first end of the strength member with the first end of the insulation layer along the exterior surface. The strength member is pre-tensioned to carry any additional tensile loads on the cord, at least initially. The cord assembly may also include a strain relief member molded over the first end of the strength member and the securing element.

1. A cord assembly for an electronic device, comprising: a cord including an insulation layer having a first end with an exterior surface and at least one electrical conductor extending within the insulation layer;a strength member extending within the insulation layer generally alongside of the at least one conductor and including a first end extending beyond the insulation layer first end, the strength member first end further extending back along the exterior surface of the insulation layer under a pre-tension force;a securing element configured to crimp on to the strength member and insulation layer and lock the pre-tensioned first end of the strength member with the first end of the insulation layer; anda molded member secured to the cord at the first end of the insulation layer, a portion of the molded member being molded over the first end of the strength member and the securing element;wherein the strength member is pre-tensioned such that any additional tensile loads placed on the cord are carried at least initially by the strength member. 2. The cord assembly of claim 1, wherein the strength member includes a Kevlar strand. 3. The cord assembly of claim 1, wherein the securing element includes a flange, the flange extending radially outwardly from the cord and held within the molded member. 4. The cord assembly of claim 3, wherein the molded member is a strain relief member and includes a connecting notch dividing the molded strain relief member into forward and rear portions and adapted to mate with a rigid housing of a peripheral device. 5. The cord assembly of claim 4, wherein the flange of the crimping member is disposed within the forward portion of the strain relief member so as to be positioned within the rigid housing to strengthen the connection between the peripheral device and the cord assembly. 6. The cord assembly of claim 1, further comprising: a pre-tensioning element engaging the first end of the strength member to pre-tension the strength member, wherein a portion of the molded member is molded over the pre-tensioning element. 7. The cord assembly of claim 6, wherein the pre-tensioning element is a coil spring, and the first end of the strength member engages the coil spring to compress the spring, which results in pre-tensioning of the strength member. 8. The cord assembly of claim 7, wherein the coil spring abuts the first end of the insulation layer, the coil spring being compressed between the insulation layer and the first end of the strength member. 9. The cord assembly of claim 1, wherein the insulation layer of the cord includes a second end with a second exterior surface, the strength member includes a second end extending beyond the second end of the insulation layer, and the assembly further comprises: a second securing element to couple the second end of the strength member with the second end of the insulation layer at the second exterior surface. 10. The cord assembly of claim 9, wherein the second securing element includes a crimping member configured to be crimped around the second end of the strength member and the insulation layer to maintain pre-tension on the strength member. 11. The cord assembly of claim 1, further comprising: a connector configured to couple with the electronic device, the connector including a connector housing with front and rear ends, a contact plate attached to the front end of the connector housing, and the molded member is a pre-mold member molded over an end of the strength member and the securing element;wherein the pre-mold member receives the at least one conductor between the contact plate and the cord. 12. The cord assembly of claim 11, further comprising: a strain relief member molded at least partially between the connector housing and the pre-mold member, the strain relief member extending beyond the rear end of the connector housing. 13. The cord assembly of claim 11, wherein the connector housing further includes engagement members configured to couple the connector to the electronic device, the engagement members being adapted to break away from the electronic device before a tensile load on the cord is carried by the at least one conductor or the insulation layer. 14. The cord assembly of claim 11, further comprising: a pre-tensioning element engaging the end of the strength member to pre-tension the strength member, wherein a portion of the pre-mold member is molded over the pre-tensioning element. 15. A cord assembly comprising: a cord having at least one electrical conductor extending in an insulation layer having an end;a strength member extending in the insulation layer generally alongside of the conductor;an end of the strength member extending out of the end of the insulation layer and extending back along an external surface of the insulation layer under a pre-tension force;a securing element configured to crimp on to the strength member and insulation layer and lock the pre-tensioned end of the strength member with the insulation layer to maintain pre-tension on the strength member;a plug member secured at the end of the cord, a molded member of the plug member being molded over the end of the strength member and the securing element. 16. The cord assembly of claim 15 wherein the strength member is a Kevlar strand. 17. The cord assembly of claim 15 further comprising a tensioning element, the end of the strength member engaging the tensioning element to create a pre-tension force on the tensioning element, the molded member of the plug member being molded over the tensioning element and the end of the strength member. 18. The cord assembly of claim 17 wherein the tensioning element is a coil spring, the end of the strength member engaging the coil spring to compress the spring for creating the pre-tension force.
