Abstract
A resilient connector uses a spring made from a cylindrical tube. The wall of the tube is cut in a helix along the central portion of the tube to form the spring. One or more plungers within the spring have a tip extending past a first end of the spring and a second end attached to the spring. Each plunger is a pin or a pair of coaxial conductors separated by a dielectric sheath. One of the coaxial conductors is a conductive layer on the sheath. A double ended connector uses a spring made as described above with a pair of plungers attached one each to each end of the spring.
