Plug-in connector assembly

A plug-in connector assembly comprising

• a first plug-in connector element with at least one first contact face,
• a second plug-in connector element with at least one second contact face,
• and a contact element for establishing an electrical contact between the first plug-in connector element and the second plug-in connector element,
• wherein the first plug-in connector element and the second plug-in connector element are connectable to each other in the direction of a plug-in axis from an unplugged state to a plugged state,
• wherein the contact element has at least one contact strip extending around the center axis and having a contact-strip-side contact face, and a plurality of contact tabs extending away from the contact strip in the direction of the center axis and having contact-tab-side contact faces,
• wherein the at least one contact strip can be brought into contact with the first contact face by means of the contact-strip-side contact face and the contact tabs can be brought into contact with the second contact face by means of the contact-tab-side contact faces, and
• wherein the contact-strip-side contact face and the first contact face are formed in such a way:
• wherein, in the unplugged state, the contact-strip-side contact face and the first contact face run angularly inclined at an angle relative to each other over a region seen in cross-section through the center axis,
• wherein, in the plugged state, the contact-strip-side contact face and the first contact face can be brought into planar contact with each other in said region or in at least part of said region,
• wherein said region, in which said contact faces run angularly inclined relative to each other in the unplugged state, forms a first region, wherein the first region is adjoined by a second region, in which the contact-strip-side contact face and the first contact face are in planar contact with each other in the unplugged state and
• wherein, in the plugged state, the contact-strip-side contact face in the second region is raised from the first contact face.
