Devices and methods for connecting to a metallic shield of a cable
The present disclosure describes various devices and methods for the reconstruction or restoration of a metallic shield of a cable, which provide a holding feature for simplifying the installation of an electrically-conductive member on the metallic shield and improving the reliability of the connection. Both factory-supplied and field-installable holding features are described.
1. A method for connecting to a metallic shield of a cable, the method comprising:
wrapping an electrically conductive member comprising a metal braid at least partially around the metallic shield of the cable to establish electrical connection between the electrically conductive member and the metallic shield, the electrically conductive member being fixed to a spring member prior to the wrapping; and
after the wrapping, applying force to the electrically conductive member with the spring member to hold the electrically conductive member against the metallic shield, wherein the applying includes:
pulling on a loop of an unwinding feature of the spring member to unroll the spring member, and
allowing the spring member to re-roll around the electrically conductive member to apply the force.
2. The method of claim 1 , wherein the loop is a preformed metallic loop that is unrolled and then re-rolled to hold the electrically conductive member against the metallic shield of the cable.
3. The method of claim 1 , wherein the spring member is configured to hold the electrically conductive member against the metallic shield of the cable with a constant pressure while allowing for expansion and contraction of the metallic shield.
4. The method of claim 3 , wherein the spring member is a constant force spring.
5. The method of claim 1 , wherein the electrically conductive member is fixed to the spring member via a conductive sheet.
6. The method of claim 5 , wherein the conductive sheet is fixed to the spring member by a fastening feature.
7. The method of claim 5 , wherein the conductive sheet includes at least one slit, and wherein the electrically conductive member is threaded through the at least one slit to secure thereto.
8. The method of claim 7 , wherein the metal braid is threaded through one of the at least one slit.
9. A method for connecting to a cable, the method comprising:
wrapping an electrically conductive member at least partially along a metallic shield of the cable to establish electrical connection between the electrically conductive member and the metallic shield, the electrically conductive member including at least one metal braid; and
deploying a holding feature around the wrapped electrically conductive member to hold the electrically conductive member against the metallic shield of the cable, the holding feature including a spring and a conductive sheet fixed to the spring, the spring and the electrically conductive member being separate and distinct structures;
wherein the conductive sheet includes at least one slit, and the electrically conductive member is extended through the at least one slit to secure thereto, such that the electrically conductive member is fixed to the spring via the conductive sheet.
10. The method of claim 9 , wherein (i) the spring is provided with the electrically conductive member factory-installed thereon or (ii) the spring is field-installable on the electrically conductive member via a holding tab or mating features.
11. The method of claim 9 , further comprising grasping and pulling an unwinding feature to unroll the spring and then wrapping the spring around the wrapped electrically conductive member.
12. The method of claim 11 , wherein the unwinding feature includes a finger-sized loop attached to the spring.
13. The method of claim 9 , wherein the at least one metal braid is extended through the at least one slit.
