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 device for connecting to a metallic shield of a cable, comprising:
an electrically-conductive member comprising a metal braid, the electrically-conductive member configured to wrap at least partially around the metallic shield of the cable, thereby providing a direct mechanical and electrical connection thereto;
a holding feature comprising a constant force spring, the holding feature configured to be deployed around the wrapped conductive member to bold the conductive member against the metallic shield of the cable; and
an unwinding feature configured for grasping and pulling to unroll the constant force spring around the wrapped conductive member,
wherein the conductive member is fixed to the constant force spring, and
wherein the unwinding feature comprises a loop disposed through an axial opening of the constant force spring.
2. The device of claim 1 , wherein the unwinding feature is fixed to the constant force spring.
3. The device of claim 1 , wherein the conductive member comprises copper.
4. The device of claim 1 , wherein the conductive member is tin plated.
5. The device of claim 1 , wherein the conductive member is fixed to the constant force spring by a fastening feature.
6. The device of claim 5 , wherein the fastening feature comprises a rivet.
7. The device of claim 1 , wherein the conductive member is fixed to the constant force spring without a fastening feature.
8. The device of claim 7 , wherein the constant force spring includes a slit, and the conductive member is threaded through the slit and bent to secure thereto.
9. The device of claim 1 , wherein the conductive member is fixed to the constant force spring via a sheet.
10. The device of claim 9 , wherein the sheet is fixed to the constant force spring by a first fastening feature, and the conductive member is fixed to the sheet by a second fastening feature, wherein at least one of the first fastening feature and the second fastening feature comprise at least one rivet.
11. The device of claim 9 , wherein the sheet is fixed to the constant force spring by a first fastening feature, and wherein the sheet includes at least one slit, and the conductive member is threaded through the at least one slit to secure thereto.
12. The device of claim 9 , wherein the sheet is merged with the constant force spring.
13. The device of claim 12 , wherein the sheet includes at least one slit, and the conductive member is threaded through the at least one slit to secure thereto.
14. The device of claim 9 , wherein the sheet is positioned in line with the conductive member.
15. The device of claim 1 , wherein the conductive member and the constant force spring are provided as separate, unattached components,
wherein the constant force spring includes a holding tab integral with the spring or fixed thereto by a fastening feature; or
wherein the conductive member and the constant force spring include mating features configured to be connected in the field.
16. The device of claim 15 , wherein the constant force spring includes a holding tab fixed thereto by a rivet.
17. The device of claim 15 , wherein the conductive member and the constant force spring include mating features configured to be connected in the field, said mating features comprising a pin on the conductive member and a corresponding hole on the constant force spring.
18. The device of claim 1 , wherein the conductive member is positioned perpendicular to the constant force spring.
19. The device of claim 1 , wherein the conductive member is positioned in line with the constant force spring.
20. A device for connecting to a metallic shield of a cable, comprising: an electrically-conductive member comprising a metal braid; a holding feature comprising a constant force spring; and an unwinding feature configured for grasping and pulling to install the constant force spring, wherein the conductive member is fixed to the constant force spring, and wherein the unwinding feature comprises a loop disposed through an axial opening of the constant force spring, wherein the conductive member is fixed to the constant force spring via a sheet, wherein the sheet is fixed to the constant force spring by a first fastening feature, and wherein the sheet includes at least one slit, and the conductive member is threaded through the at least one slit to secure thereto.
