- 15. The assembly of claim 12 wherein the spring shield includes a retention feature, the housing defines a cable-receiving cavity for receiving the end of the cable mounted thereto, and the housing further defines a ledge associated with and adjacent to the cavity, the retention feature of the spring shield co-acting with the ledge of the cavity to secure the spring shield and cable within the housing.
- 16. The assembly of claim 15 wherein the retention feature of the spring shield includes a slot defined within the spring shield and an edge of the spring shield adjacent the slot, the edge co-acting with the ledge.
- 17. The assembly of claim 12 wherein the spring shield includes an impedance tuning feature comprising a slot defined within the spring shield and a tab associated with the slot, the tab being manipulated to fine-tune an impedance of the first member and spring shield at the end of the coaxial cable.
- 18. The assembly of claim 12 wherein the spring shield is stamped out of a sheet in a relatively flat state and is rolled to a final form.
- 19. A compression coaxial cable for being coupled to a substrate, the cable having an end for being inserted into a housing having a contacting face, the cable also having a signal conductor and an outer shield, the cable further having first and second members mounted to and electrically coupled to the signal conductor and the outer shield, respectively, at the end of the cable, each of the first and second members having a deflectable portion for projecting from the housing at the contacting face, wherein upon coupling the housing to the substrate such that the contacting face of the housing faces toward and contacts the substrate, the deflectable portions each electrically contact corresponding surfaces on the substrate, and wherein upon urging the housing toward the substrate, the deflectable portions each deflect and withdraw into the housing.
- 20. The cable of claim 19 wherein the end of the cable is stripped of, in decreasing lengths from a face of the end, a jacket, the outer shield, and the dielectric to expose a length of the signal conductor, a length of the dielectric, and a length of the outer shield.
