1. A treatment arrangement for the treatment of a surface of a body with a dielectric barrier plasma, comprising:
an electrode arrangement in which at least two electrodes are disposed in a base section of the electrode arrangement, wherein the electrode arrangement is fully shielded with respect to a surface to be treated by a dielectric, and wherein the electrode arrangement extends by a terminal conductor into a contacting projection of the dielectric;
a contacting element comprising a receiving opening for the contacting projection;
an AC high-voltage source;
a lever arrangement for opening and closing the receiving opening and for applying contact pressure on a contact pin through a prefabricated recess in the dielectric onto at least one electrode of the at least two electrodes for guiding a terminal of the AC high-voltage source onto the at least one electrode;
wherein the at least two electrodes that are disposed in the base section are isolated from one another by the dielectric, the at least one electrode of the at least two electrodes is supplied with high-voltage from the AC high-voltage source for generation of the dielectric barrier plasma, and each of the at least two electrodes extend by a terminal conductor into the contacting projection;
wherein there is one recess in the dielectric and one contact pin in the contact element for each terminal conductor;
wherein the at least two electrodes are enabled for generating the dielectric barrier plasma when energized with AC high-voltage from the AC high-voltage source;
wherein at least one of the contact pins in the contacting element is surrounded with a dielectric sheath and comprises a non-insulated end for establishing contact with the corresponding electrode of the at least two electrodes; and
wherein the at least one dielectric sheath is oversized with respect to the corresponding recess in the dielectric in a radial direction, and wherein the at least one dielectric sheath, by means of the lever arrangement, is press-fitted into the dielectric so as to avoid an air gap when the non-insulated end of the contact pin contacts the corresponding electrode and a sparkover or flashover between the contact pins of the terminal conductors in the contacting projection is avoided.
