a coaxial adapter comprises an adapter body which includes a forward projecting member aligned along a connector axis . the adapter also includes an outer contact fixed to the adapter body such that a first electrical connection is made between the outer contact and the adapter body by the fixation . a dielectric is disposed at least partially within an internal bore of the adapter body or an internal bore of the outer contact and an inner contact is disposed at least partially within an internal bore of the dielectric . the forward projecting member of the adapter body makes a second electrical connection with the outer contact separate from the first electrical connection , there being no electrical connection between the adapter body and the outer contact between the first electrical connection and the second electrical connection .
