Abstract
A pair of contact or capacitive HF couplers for drill stem components. Each of the first and second couplers includes a central conductor, a supplemental conductor, and an annular dielectric mechanism. The dielectric mechanism is disposed between the conductors. The conductors are isolated from each other. The supplemental conductor includes two electrical contact surfaces. The central conductor includes an electrical contact surface or electrode such that the couplers are capacitive. The central conductors of the first and second couplers interact electrically in the coupled state. The supplemental conductors of the first and second couplers are in electrical contact in the coupled state. The supplemental conductors surround the central conductors. In the mounted state, the supplemental conductors form a shielding for the central conductors.
