Clamping body and connecting terminal for an electric conductor

A clamping body with an opening for a plug-in part, said clamping body being formed from an integral sheet-metal punched part by bending processes;

• wherein the sheet-metal punched part has a central portion upon which a spring arm portion is arranged on a first side and a contact surface portion is arranged on a second side,
• wherein, starting from the central portion, the spring arm portion is formed as a first spring arm and a second spring arm, which are arranged on the central portion in a V-shape, the first and second spring arms being divided into a first part and an adjoining second part respectively with a respective free end, and the respective first part being bent upwards almost vertically and the respective adjoining second part being arranged bent downwards such that the respective free end opposes the contact surface portion which is bent upwards almost vertically from the central portion,
• wherein respective adjoining downwardly bent second parts in the opening form first and second guide surfaces into which the plug-in part plugged, the respective first part exerts a spring force respectively in a direction of the contact surface portion, whereby the plug-in part plugged in via the guide surfaces is fixed;
• and
• wherein the second part of the first spring arm is shorter than the second part of the second spring arm such that the respectively free ends oppose the contact surface portion which is likewise bent upwards almost vertically from the central portion at different locations.
