- Actuating formed cam is hooked behind, so that when a
- the invention is based on the object, a connection terminal and a
- connection terminal blocks which are characterized by a simplified structure and are easy to operate for a user.
- connection terminal has a housing, a current bar arranged in the housing, a clamping spring arranged in the housing for clamping the conductor to be connected against the current bar, and a
- Actuating element for transferring the clamping spring into a clamping position and into an open position, the actuating element having a rotating element mounted about a first axis of rotation and a lever element mounted about a second axis of rotation, the clamping spring being mounted on the rotating element and the clamping spring following a rotary movement of the rotating element and wherein the rotary element is engaged with the lever element in such a way that upon a rotary movement of the lever element the second axis of rotation the rotary element is rotated about the first axis of rotation arranged at a distance from the second axis of rotation and the clamping spring can be transferred into the open position and into the clamping position.
- the actuating element for actuating the clamping spring is now formed in two parts, in that the actuating element is formed from a lever element and a rotary element.
- the lever element and the rotary element are two separate components that interact with each other when the clamping spring is actuated.
- the lever element and the rotary element each have a separate axis of rotation, so that the actuating element has two axes of rotation which are different from one another and which are arranged at a distance from one another.
- the actuating element can be actuated by a user directly via the lever element, so that an additional tool for actuating the actuating element is not necessary.
- the clamping spring is mounted on the rotary element of the actuating element so that the clamping spring can follow the rotary movement of the rotary element at least in some areas, which means that at least part of the clamping spring can be rotated together with the rotary element.
- the clamping spring can thus be transferred to the
- the open position and the clamping position can be rotated at least partially together with the rotary element about the first axis of rotation. This enables a very compact arrangement of the clamping spring with the actuating element. In addition, the movement of the actuating element can be transmitted to the clamping spring without friction losses in order to transfer the clamping spring into the open position and the clamping position.
- the clamping spring is preferably mounted on the rotary element in such a way that the clamping spring extends around the first axis of rotation.
- the clamping spring can thus be positioned on the rotary element in such a way that the clamping spring engages around the axis of rotation.
- the clamping spring can be shaped such that the clamping spring engages around the axis of rotation in a U-shape.
- the clamping spring can thus be positioned particularly close to the axis of rotation of the rotary element, so that the rotary movement of the
- Rotary element can be transmitted directly to the clamping spring.
- the clamping spring is preferably designed as a leg spring which has a
- Rotary element extend by the arcuate portion engages around the axis of rotation.

- Rotary movement of the rotary element can follow by the clamping leg of the
- the clamping spring is rotated or pressed in the direction of the retaining leg of the clamping spring by the rotational movement of the driver during a transfer from the clamping position to the open position, so that the distance between the clamping leg and the retaining leg is reduced and the clamping spring is tensioned.
- the retaining leg preferably remains in its position when the clamping spring is transferred into the open position and into the clamping position.
- the rotating element can have an inner part and an outer part.
- the inner part can be arranged radially on the inside of the rotary element and the outer part can be arranged radially on the outside of the rotary element, so that the outer part can radially surround the inner part.
- the inner part can be fixedly attached to the first axis of rotation, whereas the outer part can be designed to be rotatable relative to the inner part and thus the rotary element can be rotated about the first axis of rotation via the outer part of the rotary element.
- the clamping spring can be fixedly positioned on the inner part via its arcuate section. The driver for actuating the clamping leg of the clamping spring can be formed on the outer part.
- lever element and the rotary element interact in such a way that upon a rotary movement of the lever element in a
- the rotary element rotates about a direction of rotation opposite to the rotary movement of the lever element.
- the lever element and the rotary element are thus preferably in
- the lever element can be positioned in the connecting terminal in such a way that the second axis of rotation of the lever element can be slidably mounted in the housing.
- the lever element can not only perform a rotary movement about the second axis of rotation, but the lever element can simultaneously also perform a translational movement within the housing, so that the second axis of rotation of the lever element relative to the first axis of rotation of the rotating element within the housing
- a guide contour can be formed on the housing itself, within which the second axis of rotation can be displaced so that the displacement movement of the second axis of rotation can take place in a controlled manner.
- the rotary element can have a nose which can be in engagement with a nose of the lever element.
- the nose of the lever element can press on the nose of the rotary element, so that when the lever element rotates, the nose of the lever element exerts a force on the nose of the rotary element, so that the rotary element also executes a rotary movement.
- the two lugs can be designed such that when transferred into the open position and into the
- the nose of the lever element can slide along the nose of the rotary element in order to transmit the rotary movement of the lever element to the rotary element.
- the rotary element has several teeth and that the lever element has several teeth, the teeth of the
- Rotary element can be in engagement with the teeth of the lever element.
- a tooth system can thus be formed between the lever element and the rotary element in order to be able to transmit the rotary movement of the lever element to the rotary element. This allows a force / path translation between the lever element and the
- Rotary element are formed.
- a very controlled guidance between the lever element and the rotary element can be formed by the toothing.
- the lever element in the open position the actuating element and in particular the lever element automatically remains in its position without a user having to hold the actuating element in the open position.
- the lever element is rotatable through an angle ⁇ > 90 °.
