Bus bar piece and clamping spring configuration for a conductor connection terminal

A contact insert for a conductor connection terminal, comprising:

• a bus bar piece;
• and
• a clamping spring having a clamping leg with a clamping edge to connect an electrical conductor, the clamping edge of the clamping leg and the bus bar piece forming a clamping point for the electrical conductor to be connected;
• and
• at least two lateral webs arranged on the clamping spring on mutually opposite sides of the clamping spring, free ends of the lateral webs being connected to one another by a transverse web,
• wherein the lateral webs and the transverse web form a circumferentially closed aperture on the clamping spring,
• wherein the bus bar piece extends between the lateral webs, at least when the clamping point is closed,
• wherein the bus bar piece passes through the circumferentially closed aperture at least twice, and
• wherein the lateral webs are designed to be V-shaped, wherein the lateral webs project from the clamping spring in one direction and wherein the lateral webs each form an acute angle.
