Abstract

A conductor connection terminal having several spring force clamping connections, each of which has at least one clamping spring, which form a clamping point for clamping an electrical conductor with an associated busbar piece. The invention also relates to an electrical connector having at least one such conductor connection terminal.

First claim

What is claimed is:

1. A conductor connection terminal comprising:
at least two spring force clamping connections, each having at least one clamping spring that forms a clamping point for clamping an electrical conductor with an associated busbar piece; and
a rotary actuator that is a manual actuating element, the rotary actuator being rotatable about an axis of rotation and which, in the event of a rotation by a first rotation angle, is set up to deflect several or all of the clamping springs and thereby open the clamping points associated therewith,
wherein the axis of rotation of the rotary actuator runs at least approximately parallel and/or in alignment with a conductor insertion direction of the several or all of the clamping springs to be actuated by the rotary actuator.

2. The conductor connection terminal according to claim 1 , wherein the rotary actuator is rotatably mounted on a first housing part of the conductor connection terminal.

3. The conductor connection terminal according to claim 2 , wherein the rotary actuator is a second housing part of the conductor connection terminal.

4. The conductor connection terminal according to claim 3 , wherein the second housing part is formed as a cover part, which covers an interior of the first housing part at least partially.

5. The conductor connection terminal according to claim 1 , wherein the several or all of the clamping springs to be actuated by the rotary actuator are arranged in a ring arrangement about a center and/or a center axis of the conductor connection terminal.

6. The conductor connection terminal according to claim 1 , wherein the several or all of the clamping springs actuated by the rotary actuator in the rotation of the rotary actuator by the first rotation angle exert forces on the rotary actuator, which are in a force equilibrium.

7. The conductor connection terminal according to claim 1 , wherein the rotary actuator has several deflection elements by which the respective clamping springs are deflected during the rotation of the rotary actuator by the first rotation angle.

8. The conductor connection terminal according to claim 7 , wherein at least one of the deflection elements is flexibly coupled with the rotary actuator.

9. The conductor connection terminal according to claim 7 , wherein the rotary actuator is rotatably mounted on a first housing part of the conductor connection terminal, and wherein the first housing part has a deflection contour for the deflection of at least one of the deflection elements.

10. The conductor connection terminal according to claim 1 , wherein the rotary actuator is infinitely rotatable about the axis of rotation and/or in only one direction of rotation, or has an end stop to limit the rotational movement.

11. The conductor connection terminal according to claim 1 , wherein an outer circumference of the rotary actuator has a grip surface on which the rotary actuator is to be operated manually, and wherein the grip surface extends over the entire outer circumference or one or more sections of the outer circumference.

12. The conductor connection terminal according to claim 1 , wherein the rotary actuator is set up to deflect one or more clamping springs in an event of a rotation by a second rotation angle that is greater than the first rotation angle and thereby to open the associated clamping points which are not deflected when rotating by the first rotation angle.

13. The conductor connection terminal according to claim 1 , wherein a conductor insertion side of the conductor connection terminal has conductor insertion openings through which electrical conductors can be led to the clamping points, wherein on a side facing away from the conductor insertion side, the conductor connection terminal has plug openings that lead to electrical plug contacts arranged in the housing of the conductor connection terminal.

14. The conductor connection terminal according to claim 1 , wherein with the rotation of the rotary actuator by the first rotation angle, a total length of the conductor connection terminal does not change.

15. The conductor connection terminal according to claim 2 , wherein, in the event of the rotation of the rotary actuator by the first rotation angle, an axial position of the rotary actuator does not change relative to the first housing part.

16. The conductor connection terminal according to claim 1 , wherein the rotary actuator is set up to deflect the several or all of the clamping springs in the rotation by the first rotation angle which is less than 360 degrees or less than 180 degrees, and thereby to open the associated clamping points.

17. An electrical connector comprising at least one conductor connection terminal according to claim 1 , wherein the electrical connector is a circular connector.

18. A conductor connection terminal comprising:
at least two spring force clamping connections, each having at least one clamping spring that forms a clamping point for clamping an electrical conductor with an associated busbar piece; and
a rotary actuator that is a manual actuating element, the rotary actuator being rotatable about an axis of rotation and which, in the event of a rotation by a first rotation angle, is set up to deflect several or all of the clamping springs and thereby open the clamping points associated therewith,
wherein the several or all of the clamping springs to be actuated by the rotary actuator are arranged in a ring arrangement about a center and/or a center axis of the conductor connection terminal, and
wherein the axis of rotation of the rotary actuator runs through the ring-shaped arrangement of the clamping springs.

19. A conductor connection terminal comprising:
at least two spring force clamping connections, each having at least one clamping spring that forms a clamping point for clamping an electrical conductor with an associated busbar piece; and
a rotary actuator that is a manual actuating element, the rotary actuator being rotatable about an axis of rotation and which, in the event of a rotation by a first rotation angle, is set up to deflect several or all of the clamping springs and thereby open the clamping points associated therewith,
wherein for each of the several or all of the clamping springs to be actuated by the rotary actuator, the rotary actuator has a respective conductor opening for conducting an electrical conductor to the respective clamping point.
