1. A connection terminal for connecting an electric conductor, comprising:
a housing;
a current bar arranged in the housing;
a clamping spring arranged in the housing configured to clamp the conductor to be connected against the current bar; and
an actuation element configured to transfer the clamping spring into a clamping position and into an open position,
wherein the actuation element has a rotation element mounted about a first axis of rotation and a lever element mounted about a second axis of rotation,
wherein the clamping spring is mounted on the rotation element and the clamping spring is configured to follow a rotational movement of the rotation element at least in regions,
wherein the rotation element is configured to engage with the lever element such that during a rotational movement of the lever element about the second axis of rotation, the rotation element is configured to rotate about the first axis of rotation arranged spaced apart from the second axis of rotation, and the clamping spring is configured to be transferred into the open position and into the clamping position, and
wherein the clamping spring is mounted on the rotation element such that the clamping spring extends around the first axis of rotation.
