- Actuating element by means of which the clamping spring can be transferred from the clamped state to a non-clamped state.
- connection terminals usually have a leg spring having a retaining leg and a clamping leg, a conductor inserted into the connection terminal being able to be clamped against the busbar by means of the clamping leg.
- the clamping spring must be actuated by means of the actuating element before the conductor is inserted in order to pivot the clamping spring or the clamping leg away from the busbar so that the conductor can be inserted into the space between the busbar and the clamping spring.
- the conductor apply sufficient force to the clamping spring or the clamping leg of the clamping spring to be able to pivot the clamping leg away from the busbar without the operator having to operate the actuating element.
- the user In the case of flexible conductors, the user must first pivot the clamping spring away from the busbar by actuating the actuating element so that the flexible conductor can be inserted and clamped. Pressing the
- the invention is therefore based on the object of providing an electrical connection terminal in which the connection of flexible conductors can be simplified.
- the electrical connection terminal according to the invention is characterized in that the clamping spring is designed as a leaf spring and that a receiving element is provided, on which the leaf spring is attached, wherein the receiving element has a holding element on which the clamping spring is held in the unclamped state and from which the clamping spring is released in the clamped state, the holding element for releasing the clamping spring from the holding element
- the holding element is pivotable, the holding element having a pressure surface which can be actuated by means of the conductor to be connected to perform the pivoting movement.
- connection terminal By means of the connection terminal according to the invention, a flexible conductor can now also be connected in the connection terminal and clamped against the busbar without actuating the actuating element.
- the clamping spring is not designed as a leg spring but as a leaf spring which is elongated.
- the clamping spring thus has a leaf-shaped or strip-shaped contour.
- the clamping spring designed as a leaf spring, has a fastening area via which the clamping spring is fastened to a receiving element.
- the clamping spring has a clamping area which, in the clamped state, has direct contact with the conductor, to the conductor against the
- the receiving element to which the clamping spring is fastened with its first end section, has a holding element on which the clamping spring is held with its second end section in the clamped state in such a way that the clamping spring, in particular with its second end section forming the clamping area, is pivoted away from the busbar so that the head,
- a flexible conductor can be inserted into the space thus formed between the busbar and the clamping spring without the
- the clamping spring must be actuated beforehand with the actuating element.
- Holding element has a pressure surface which is arranged in the insertion area of the conductor into the connection terminal, so that the conductor when inserted into the
- the holding element By applying a pressure force by means of the conductor to the pressure surface, the holding element can be in a
- Insertion direction of the conductor is pivoted away.
- the clamping spring can be released from the holding element so that the clamping spring can move with its clamping area in the direction of the inserted conductor, in particular can pivot, and thereby clamp the inserted conductor against the busbar.
- Clamping area can be pivoted back in the direction of the holding element and fixed in position on the holding element, in particular latched.
- the receiving element preferably has a receiving pocket in which the clamping spring can be inserted, wherein a spring-elastic web can be formed on the receiving pocket, on which the holding element can be arranged.
- the receiving pocket is preferably designed in such a way that it surrounds the clamping spring inserted into the receiving pocket on the circumferential side, so that the clamping spring can be held securely in position in the receiving pocket.
- a resilient web, at the end of which the holding element can be arranged, can be molded onto this receiving pocket. This resilient web enables a spring movement of the holding element relative to the receiving pocket, whereby the pivoting movement of the holding element for releasing the clamping spring from the holding element can also be made possible.
- the holding element can thus execute a pivoting movement relative to the receiving pocket.
- the receiving pocket, the resilient web and the holding element are preferably formed in one piece with one another.
- the spring-elastic web can have a cross-section reduction along its length.
- the cross-sectional reduction can be designed in the form of a constriction, so that the width of the web changes along its length.
- the reduction in width and thus the reduction in cross section are preferably carried out in the direction of the holding element, so that in the area of the connection of the web to the receiving pocket the web has a greater width than in the area of the connection of the web to the holding element.
- the holding element can have two oppositely located latching lugs, wherein the latching lugs can be designed to be curved towards one another.
- the locking lugs can each have an undercut have, on which the clamping spring can be held, in particular locked, with its clamping area in the non-clamped state.

- Latching lug can be formed on a first leg and a second latching lug can be formed on a second leg of the U-shaped holding element opposite the first leg.
- the legs preferably run parallel to one another.
- the latching lugs on the other hand, can be designed to be curved towards one another, so that they can be directed towards one another starting from the connection to the legs. The locking of the clamping spring on the locking lugs can be improved.
- the clamping spring can have a clamping area by means of which the conductor can be clamped against the busbar in the clamped state, the
- Clamping area can have two actuating surfaces formed laterally on the clamping area for actuating the clamping spring by means of the actuating element. Due to the laterally molded actuation surfaces, the clamping spring can have a greater width in its clamping area than the rest of the clamping spring.
- Operating surfaces can form a pressure surface for the operating element so that the operating element can operate the clamping spring at the level of its clamping area.
- the strength of the compressive force to be applied to the clamping spring by means of the actuating element for transferring the clamping spring from the clamped state to the non-clamped state can thereby be reduced.
- the busbar is also attached to the receiving element.
- the busbar like the clamping spring, can be inserted into the receiving pocket of the receiving element.
- the clamping spring can be arranged on a bottom section of the receiving pocket and the busbar can be arranged on a ceiling section of the receiving pocket opposite the bottom section, so that the clamping spring and the busbar are opposite one another.
- the clamping spring and busbar can be arranged to run essentially parallel to one another.
- the busbar can be fastened to the receiving element by means of a latching connection.
- the actuating element is provided such that the actuating element has an actuating direction which is transverse to an insertion direction of the to be connected conductor is formed in the electrical connection terminal.
- the actuation element is preferably actuated along its longitudinal axis, so that the actuation element is preferably longitudinally displaceable in the
- Terminal is arranged.
- the actuating element is preferably arranged to be longitudinally displaceable in a direction transverse to the direction of insertion of the conductor.
- the actuation direction of the actuation element is thus preferably not configured parallel to the insertion direction of the conductor.
- the actuating element preferably has two opposite one another
- Actuating fingers for actuating the clamping spring wherein a free space can be formed between the two actuating fingers for the conductor to be connected through.
- the actuating element can thus be guided past the conductor laterally with its two actuating fingers.
- a particularly compact design of the connecting terminal can be achieved through this design of the actuating element.
- the two actuating fingers preferably extend in the direction of the longitudinal axis of the actuating element and can thus form a type of extension of the actuating element.
- connection terminal has an insulating material housing within which the busbar, the clamping spring, the
- Actuating element and the receiving element can be arranged.
- Insulating material housing can have a conductor insertion opening and a receiving opening for the actuating element, wherein the conductor insertion opening can be formed on a first side of the insulating material housing and wherein the receiving opening is provided on a second side of the extending transversely to the first side

- FIG. 1 shows an electrical connection terminal 100 for connecting an electrical conductor 200, which has a busbar 10 and clamping spring 11, with the conductor 200 being clamped against the busbar 10 by means of the clamping spring 11 for connecting the conductor 200.
- Both the clamping spring 11 and the busbar 10 are arranged on a receiving element 12.
- the clamping spring 11 is designed as a leaf spring which is leaf-shaped or strip-shaped.
- the clamping spring 11 is inserted into the receiving element 12 and fastened to the receiving element 12.
- the clamping spring 11 has a fastening area on a first end section 13, by means of which the clamping spring 11 is fastened to the receiving element 12.
- the clamping spring 11 forms its
- the clamping spring 11 clamps the conductor 200 inserted into the connection terminal 100 against the busbar 10 and thus connects it in an electrically contacting manner.
- the clamping spring 11 has two laterally molded on
- the receiving element 12 has a receiving pocket 15 and a holding element 16, the receiving pocket 15 being connected to the holding element 16 via a spring-elastic web 17.
- the holding element 16 serves to hold the clamping spring 11 in a non-clamped state, i.e. when the clamping spring 11 does not clamp a conductor 200 against the busbar 10, in particular to hold it on its second end section 14 forming the clamping area, so that a free space or Gap is formed between the busbar 10 and the clamping spring 11, as can be seen for example in Fig. 1, into which a conductor 200 can be inserted.
- the holding element 16 is U-shaped. On a wall 20 formed between two legs 18, 19 running parallel to one another, the

- the holding element 16 can be moved, in particular pivoted, relative to the receiving pocket 15.
- Retaining element 16 itself is rigid.
- the spring-elastic web 17 thus enables a pivoting movement of the holding element 16 in the pivoting direction S when a conductor 200 presses against the holding element 16 and the web 17 enables the holding element 16, when the conductor 200 is no longer clamped, back against the pivoting direction S. pivoted into its starting position so that the clamping spring can be held or latched again on the holding element 16 in the non-clamped state.
- the spring-elastic web 17 has a cross-sectional reduction 24 along its length, so that the web 17 is designed with a waist, as can be seen in particular in FIG. 6.
- the cross-sectional reduction 24 is formed in the direction of the holding element 16, so that in the area of the connection of the web 17 to the holding element 16, the web 17 has a smaller cross section and thus a smaller width than in the area of the connection of the web 17 to the receiving pocket 15.
- the receiving pocket 15 is designed in such a way that it surrounds the clamping spring 11 inserted into the receiving pocket 15 on the circumferential side.
