Abstract

The invention relates to a treatment assembly for treating the surface of a body with a dielectrically limited plasma, comprising an electrode assembly (1), in which at least one electrode (1a, 1b) is arranged in a base section of the electrode assembly (1), which is completely shielded from the surface to be treated by a dielectricum (3), and a connection conductor (6a, 6b) of which extends into a contact projection (5) of the dielectricum (3). The treatment assembly also comprises a contact element (2, 2′), which has a receiving opening (18, 18) for the contact projection (5) and a lever assembly for opening and closing the receiving opening (18, 18′) and for pressing a contact pin (31) through a prefabricated recess (14) of the dielectricum (3) onto the electrode (1a, 1b) in order to deliver a connection of a high-voltage AC source to the electrode (1a, 1b), allows a spatially close arrangement of two contact pins (31), which are connected to at least one high-voltage source, in close proximity to each other in that the electrode assembly (1) has at least two electrodes (1a, 1b), which are arranged in the base section and are insulated from each other by the dielectricum (3) and…
