The through bore for the lamp lead-in wire is formed as a first perforated bore (12) with torn skirt (20) protruding from the plane (L) of the contact plate (10) in a direction away from the insulator insert (30), and the contact plate (10), in addition to this first perforated bore (12), also includes at least two further perforated bores (14, 16, 18), each having a torn skirt (22, 24, 26) protruding from the plane (L) of the contact plate (10) in a direction opposite to the direction of the torn skirt (20) of the first perforated bore (12), towards the insulator insert (30). The contact plate (10) is optionally also provided with a continuous rim (28) protruding in a stepped manner from the plane (L) of the contact plate (10) on the side of the torn skirt (20) of the first perforated bore (12) and being at least approximately parallel to the plane (L) of the contact plate (10).
