2. The electrical connection terminal according to claim 1 , wherein the actuation arm is mounted pivotably movable in a recess of the base body.

3. The electrical connection terminal according to claim 2 , wherein a web is disposed in the recess, the actuation arm enclosing the web in a U shape.

4. The electrical connection terminal according to claim 1 , wherein at least one stop configured to limit the pivoting movement of the actuation arm is disposed on the base body.

5. The electrical connection terminal according to claim 1 , wherein a locking unit configured to lock the actuation arm in a position relative to the base body is disposed on the base body and/or on the actuation arm.

6. The electrical connection terminal according to claim 1 , wherein the base body and the actuation arm are mounted pivotably movable on a bearing element disposed on the connection terminal housing.

7. The electrical connection terminal according to claim 1 wherein the connection terminal housing comprises two conductor insertion openings, and two spring elements and two actuation elements are disposed in the connection terminal housing, the two actuation elements being rotatable counter to one another, and being positioned opposite one another such that the actuation arms of the actuation elements are arranged in succession in a division direction.

8. An electrical connection terminal, comprising:
