transmitted inwardly to the inner dielectric material on the other hand with the slots extending in a circumferential direction as shown the slots provide a large circumferential area of access to the metallic shields in a circumferential direction preferably each slot extends at least approximately 180 u00b0 around the respective coaxial cable in the alternative it is believed that by using a coaxial cable having an inner dielectric that can withstand relatively high temperatures without deformation or degradation such as aerated teflon it may be possible to eliminate the slots 56 in gripping arms 54 in such case solder would be applied along the leading or trailing or both edges of the arms where they contact the metallic shields 68 in still another alternate embodiment arms 54 again would not include slots 56 and some means on the inner surface of arms 54 for applying solder between the arms and the metallic shields 68 would be used such means could include a tin lead plating a solder top coat or a solder inlay on the inner surfaces of arms 54 the outer surfaces of the arms would be heated with a soldering iron or other tool which would cause the plating solder top coat or solder inlay to flow interconnecting the inner surface of the arms to the metallic shields once coaxial cables 40 are mechanically and electrically connected to cable receiving part 44 as shown in fig7 the cable receiving part is mounted.
