Assembly of electrode body and electrode carrier for a plasma torch

Male/female assembly (11) for a plasma torch comprising an electrode body (3) having substantially the shape of a sleeve forming the female portion and an electrode carrier (4) of substantially elongated shape forming the male portion, in which:

• the electrode body (3) comprises, over an upstream portion of its internal periphery, at least one tapping (15) within which is provided at least one recess (8) extending over all the length (d) of said tapping (15), the tapped portion (15) having, in transverse cross-section, a diameter D1, and at least one downstream portion defining a recess (16) of a diameter D2 located between the tapped upstream portion (15) and the bottom of the electrode body (3), wherein D2>D1, and
• the electrode carrier (4) comprises, over its external peripheral surface, at least one gauge (4") having at least locally a transverse cross-sectional profile corresponding to the profile of said at least one recess (8) of the electrode body (3) and at least one screw thread (15'), said gauge (4") being located between the downstream end of the electrode carrier (4) and said screw thread (15').
