Contacting device for contacting an electrical conductor to an electrical conductor trace, comprising: - a housing with a first opening that is suitable for inserting the electrical conductor into a cavity of the housing, and with a second opening that is suitable for inserting the electrical conductor trace into the cavity of the housing, - a contact bow that is arranged in the cavity of the housing, - a guide element that is arranged in the cavity of the housing, - wherein the contact bow is formed as a single element that has a first segment with one end which is suitably designed to press the conductor against the conductor trace, and a second segment from which projects a material protrusion of the contact bow that is integrated into the second segment, - wherein the contact bow in the cavity is designed so as to be curved such that the first segment is under a bending stress, and the end the first segment of the contact bow is pressed against the material protrusion by the bending stress, - wherein the contact bow is guided along the guide element in such a way that the first segment of the contact bow exhibits the bending stress, - wherein the contact bow in the cavity is designed so as to be curved such that the end segment of the second segment of the contact bow is arranged below the first opening of the housing, - wherein the second segment of the contact bow in the housing is arranged to be movable such that the second segment of the contact bow and the material protrusion are displaced if, upon insertion into the cavity, the conductor is pressed against the end segment of the second segment of the contact bow and a force thereby acts on the second segment of the contact bow, whereby the end of the first segment of the contact bow is released from resting on the material protrusion and is pressed against the conductor as a result of the bending stress of the first segment of the contact bow, so that the conductor is held in the clamping seat on the conductor trace if the conductor has been inserted into the contacting device through the first opening and the conductor trace has been inserted into the contacting device through the second opening, - wherein the second segment of the contact bow in the housing is arranged at a distance above the floor surface of the cavity, - wherein the contact bow has a third segment into which the second segment transitions, - wherein the guide element has a first structure against which the third segment of the contact bow rests, characterized in that the second segment of the contact bow, except for the material protrusion, is arranged perpendicular to the longitudinal direction of the first opening of the housing and parallel to a floor surface of the cavity, and in that the third segment of the contact bow in the housing is arranged perpendicular to the second segment of the contact bow. -
