Definitions

  • the invention relates to a connection arrangement for connecting an electrical conductor, which has a current bar, a clamping spring which can be transferred into a clamping position and into an open position, wherein in the clamping position of the clamping spring the electrical conductor to be connected is clamped against a clamping section of the current bar, a first actuating element which can be guided along a first actuating direction and by means of which the clamping spring can be transferred from the clamping position to the open position, and a second actuating element which can be guided along a second actuating direction and by means of which the clamping spring can be released from the open position, wherein the clamping spring has a holding leg and a clamping leg for clamping the conductor to be connected against the clamping section of the current bar in the clamping position of the clamping spring and a locking leg which is held in a fixed position in the open position of the clamping spring, wherein the clamping leg can be actuated by means of the first actuating element and the locking leg can be actuated by
  • connection arrangements are known, for example, from DE 203 00 266 U1 , the EP 0 052 766 A1 , the DE 20 2016 102 959 U1 , the DE 20 2016 105 826 U1 and the CN 102 969 599 A known.
  • Such connection arrangements usually have a clamping spring designed as a leg spring, which has a holding leg and a clamping leg, wherein a conductor inserted into the connection arrangement can be clamped against the current bar by means of the clamping leg of the clamping spring.
  • an actuating element is usually provided which can transfer the clamping spring from the clamped position to the open position.
  • the clamping spring In the open position, the clamping spring can be held in its position, wherein by inserting a conductor into the connection space of the connection arrangement, the clamping spring can be released from this open position by the conductor alone, so that the clamping spring can be automatically transferred back from the open position to the clamping position.
  • this is only possible with conductors which have a sufficiently large conductor cross-section so that the conductors can apply sufficient force to be able to release the locking of the clamping spring in the open position.
  • the invention is based on the object of providing a connection arrangement, a connection terminal and an electronic device, which also enable a simplified connection of flexible conductors.
  • connection arrangement is characterized in that the first actuating element has a holding contour on which the locking leg is held in the open position of the clamping spring, wherein the locking leg has a free end on which at least one holding arm is formed, via which the locking leg is held on the holding contour of the first actuating element in the open position of the clamping spring, wherein the second actuating element cooperates with the at least one holding arm during the transfer from the clamping position to the open position.
  • the connection arrangement therefore has not just one actuating element, but two actuating elements.
  • the two actuating elements are designed as two separate elements. Furthermore, the two actuating elements have two different functions.
  • the clamping spring can be moved from the clamped position to the open position using the first actuating element, in particular when a connected conductor is to be released from the clamped position.
  • the second actuating element enables the clamping spring to be released from the open position so that the clamping spring can swing or be moved back from the open position to the clamped position.
  • the actuation of the clamping spring to connect the conductor can be made easier using the second actuating element.
  • the clamping spring can thus be released from the open position using the second actuating element and does not have to be released by a pressure force applied by the conductor to the clamping spring.
  • the second actuating element can thus be actuated by a user if necessary. This can make handling much easier for the user, especially when connecting flexible conductors.
  • the first actuating element and the second actuating element are arranged relative to one another in such a way that the first actuating direction of the first actuating element is aligned parallel to the second actuating direction of the second actuating element.
  • the first actuating element and the second actuating element can thus be actuated by a user from the same side.
  • the second actuating element can be guided parallel to the first actuating element.
  • the second actuating element is preferably arranged directly adjacent to the first actuating element.
  • the clamping spring has a holding leg and a clamping leg for clamping the conductor to be connected against the clamping section of the current bar in the clamping position of the clamping spring.
  • the clamping spring also has a locking leg that extends into a conductor connection space and is held in a fixed position in the open position of the clamping spring, the clamping leg being actuated by means of the first actuating element and the locking leg being actuated by means of the second actuating element.
  • the locking leg can be arranged on the holding leg at an end of the holding leg that is remote from the clamping leg. The holding leg can thus be arranged between the clamping leg and the locking leg.
  • the locking leg can be formed in one piece with the holding leg or connected to the locking leg as a separate part, in particular connected to the locking leg in a form-fitting and/or force-fitting manner.
  • the locking leg is preferably connected to the holding leg in such a way that the locking leg is designed to be resilient or pivotable relative to the holding leg.
  • the clamping spring In the open position of the clamping spring, the clamping spring can be held, in particular locked, on the first actuating element via the locking leg.
  • the locking leg In the open position of the clamping spring, the locking leg can apply a compressive force to the first actuating element, which can act on the first actuating element in the opposite way to a compressive force applied by the clamping leg to the actuating element in the open position of the clamping spring.
  • the locking leg can have a pressure surface, whereby the pressure surface is formed by the conductor to be connected in order to transfer the clamping spring from the open position to the clamping position. can be actuated and by actuating the pressure surface, the locking leg can be brought out of engagement with the actuating element.
  • the locking leg can have a pressure surface which can be arranged in alignment with an insertion area of the conductor in the connection arrangement and thus as an extension of a conductor insertion opening of a housing of a connection terminal, so that the conductor can strike the pressure surface of the locking leg when inserted into the connection arrangement or into the conductor connection space.
  • the locking leg By applying a pressure force to the pressure surface using the conductor, the locking leg can be set in a pivoting or tilting movement in the direction of conductor insertion, so that the locking leg can be pivoted or tilted away from the first actuating element in the conductor insertion direction.
  • the locking leg By pivoting the locking leg, the locking leg can be brought out of engagement with the actuating element and thus released from the actuating element, so that the actuating element and thus the clamping spring can be transferred from the open position to the clamped position without manual assistance.
  • This special mechanism makes it particularly easy to connect a conductor simply by inserting the conductor in order to release the clamping spring and move it from the clamped position to the open position.
  • the conductor to be connected is very flexible or has a very small conductor cross-section, so that not enough force can be applied to the locking leg or the pressure surface of the locking leg via the conductor itself to release the locking leg from the actuating element in the open position of the clamping spring, the locking leg can be released from the locking position with the first actuating element using the second actuating element.
  • the second actuating element can therefore be used to help connect the conductor, depending on the conductor cross-section of the conductor to be connected.
  • the second actuating element By means of the second actuating element, a different area of the clamping spring can be actuated than with the first actuating element, since the first actuating element preferably cooperates with the clamping leg and the second actuating element preferably cooperates with the locking leg.
  • the first actuating element has a holding contour.
  • the holding contour enables a secure and defined holding of the locking leg on the first actuating element in the open position of the clamping spring.
  • the locking leg applies the pressure force to the first actuating element.
  • the holding contour is preferably designed in the form of a special surface shape on the first actuating element itself.
  • the first actuating element can have a U-shape in cross-section.
  • the first actuating element can have a first actuating arm and a second actuating arm arranged at a distance from the first actuating arm, wherein the holding contour can then be formed on the first actuating arm and on the second actuating arm.
  • the two actuating arms are preferably aligned parallel to one another. A free space is formed between the two actuating arms, into which the conductor to be connected can be inserted and through which the conductor to be connected can be guided in the direction of the locking leg.
  • the conductor connection space formed between the current bar and the clamping spring can be laterally delimited by the first actuating arm and the second actuating arm, so that the two actuating arms can guide the conductor to be connected and prevent the conductor from slipping sideways.
  • the holding contour on the first actuating arm is preferably formed symmetrically to the holding contour arranged on the second actuating arm.
  • the locking leg can be held, in particular locked, on the two actuating arms or on the two holding contours of the two actuating arms in the open position of the clamping spring.
  • the locking leg has a free end on which at least one holding arm is formed, via which the locking leg is held on the holding contour of the first actuating element in the open position of the clamping spring, wherein the second actuating element interacts with the at least one holding arm when moving from the clamping position to the open position.
  • the at least one holding arm preferably extends transversely to the longitudinal extent of the locking leg. In the locked position, the locking leg can engage over the first actuating element in the region of the holding contour with its at least one holding arm, so that the at least one holding arm can rest on the first actuating element in this locked position and can thereby apply a pressure force to the first actuating element via its at least one holding arm.
  • the locking leg can have a T-shape at its free end, with which the locking leg can be held on the two actuating arms. Due to the T-shape, the locking leg can have a first laterally projecting Holding arm and a second laterally projecting holding arm, wherein the locking leg can be held on the holding contour of the first actuating arm with the first holding arm and the locking leg can be held on the holding contour of the second actuating arm with the second holding arm.
  • the two holding arms are then preferably formed on the locking leg in such a way that they extend away from one another.
  • the second actuating element can have at least one actuating finger, which can interact with the at least one holding arm when the clamping spring is transferred from the open position to the clamping position.
  • the clamping spring can thus be actuated by means of the second actuating element via the at least one holding arm of the locking leg.
  • the actuating finger preferably extends in the longitudinal direction of the second actuating element.
  • the second actuating element can be guided with its at least one actuating finger along the at least one holding arm of the locking leg and press against the at least one holding arm in such a way that the at least one holding arm can be pushed away or pushed away from the first actuating element.
  • a sliding surface can be formed on the second actuating element, in particular on the at least one actuating finger of the second actuating element, which can slide along the locking leg or along the at least one holding arm of the locking leg in order to release the locking leg from the first actuating element.
  • the sliding surface is preferably formed as an inclined surface.
  • the second actuating element can preferably also have two actuating fingers, so that a first actuating finger can interact with the first holding arm and a second actuating finger can interact with the second holding arm.
  • the two actuating fingers are preferably designed symmetrically to one another.
  • the two actuating fingers can enable simultaneous actuation of the two holding arms of the locking leg.
  • the two actuating fingers preferably extend parallel to one another in the longitudinal direction of the second actuating element.
  • the at least one actuating finger can, for example, be designed to be so long that when the second actuating element is guided along the second actuating direction, the at least one actuating finger can be guided laterally past the clamping section of the current bar to actuate the locking leg. If the second actuating element has two actuating fingers, these two actuating fingers are preferably designed to be the same length, so that both actuating fingers can be guided laterally past the clamping section of the current bar to actuate the locking leg. The second actuating element can thus grip the clamping section of the current bar in a U-shape with its two actuating fingers, particularly when the clamping spring or the locking leg of the clamping spring is actuated.
  • the two actuating fingers are preferably spaced apart from one another so far that, particularly when the clamping spring or the locking leg of the clamping spring is actuated, the two Actuating fingers can be guided past the clamping section of the current bar on two opposite side surfaces of the clamping section of the current bar.
  • At least one recess can be formed on the clamping section of the current bar, in which the at least one actuating finger can be guided as it passes.
  • the at least one actuating finger can thus penetrate directly through the clamping section of the current bar.
  • the clamping section of the current bar can have two recesses, so that the two actuating fingers can each penetrate through one of the two recesses in order to actuate the clamping spring or the locking leg of the clamping spring.

  • the at least one actuating finger of the second actuating element is preferably so short that it is not guided laterally past the clamping section of the current bar.
  • the at least one holding arm can then be longer and laterally overlap the current bar.
  • the at least one holding arm can then extend out of the conductor connection space. No recess is then necessary on the current bar, as a result of which the cross section of the current bar for the current-carrying capacity would not be reduced.
  • the at least one laterally projecting holding arm can then have an extension along the second actuation direction of the second actuating element.
  • the at least one holding arm can then have an L-shape.
  • two holding arms can be provided, which can be mirror-symmetrical to one another. Both holding arms can then be designed to be so long that both holding arms laterally overlap the clamping section of the current bar, in particular laterally overlap on two opposite side surfaces of the current bar.
  • the first actuating element can have a spring element, by means of which the first actuating element can be spring-loaded in the open position of the clamping spring.

  • the clamping spring 112 and the first actuating element 119 are braced together so that the clamping spring 112 and the first actuating element 119 form a closed force system in which the first actuating element 119 is held in position by the clamping spring 112 without additional aids and the clamping spring 112 is in turn held in position by the first actuating element 119.
  • the clamping of the first actuating element 119 with the clamping spring 112 is achieved by the clamping spring 112 applying two opposing pressure forces D1, D2 to the first actuating element 119 in the open position. These two opposing pressure forces D1, D2 allow the first actuating element 119 and thus also the clamping spring 112 to be held in a stable, stationary position in the open position of the clamping spring 112.
  • the first pressure force D1 acts on the first actuating element 119 in the opposite direction to the first actuating direction B1.
  • the first pressure force D1 is applied to the first actuating element 119 by the clamping leg 114, in particular by the side tabs 123a, 123b of the clamping leg 114.
  • the side tabs 123a, 123b press onto the actuating surfaces 121a, 121b of the first actuating element 119 with the first pressure force D1 applied by the spring action of the clamping leg 114.
  • the second pressure force D2 acts on the first actuating element 119 in the first actuating direction B1.
  • the second pressure force D2 is applied to the first actuating element 119 by the locking leg 116 of the clamping spring 112.
  • the locking leg 116 is held with its free end 125 on the first actuating element 119, in particular on the two actuating arms 120a, 120b of the first actuating element 119, in particular locked on the first actuating element 119.
  • the free end 125 of the locking leg 116 has a T-shape in that the free end 125 has two holding arms 126a, 126b projecting outwards at the sides. In the open position, the locking leg 116 is held with its first holding arm 126a on the first actuating arm 120a and with its second holding arm 126b on the second actuating arm 120b.
  • a holding contour 127 is formed on each of the two actuating arms 120a, 120b.
  • the holding contour 127 is formed at a distance from the actuating surfaces 121a, 121b on the first actuating element 119.
  • the two holding arms 126a, 126b of the locking leg 116 rest against the holding contour 127 of the actuating arms 120a, 120b in order to hold the locking leg 116 in a fixed position.
  • a conductor 300 to be connected is inserted into the conductor connection space 117 via the conductor insertion opening 211 of the housing 210 in the conductor insertion direction E, the conductor 300 strikes the pressure surface 118 of the locking leg 116 of the clamping spring 112, which is arranged in alignment with the conductor insertion opening 211, as shown in Fig. 2 can be seen.
  • the locking leg 116 can be pivoted in the conductor insertion direction E, so that the locking leg 116 can come out of engagement with the holding contour 127 of the first actuating element 119.
  • the connection arrangement 100 has a second actuating element 128.
  • This second actuating element 128 enables the clamping spring 112 to be released from its open position in order to be transferred to the clamping position.
  • the second actuating element 128 cooperates with the locking leg 116, in particular with the holding arms 126a, 126b of the locking leg 116.
  • the second actuating element 128 therefore does not cooperate with the clamping leg 114 of the clamping spring 112.
  • the first actuating element 119 and the second actuating element 128 thus interact with the clamping spring 112 at different areas of the clamping spring 112.
  • the second actuating element 128 can be actuated independently of the first actuating element 119.
  • the second actuating element 128 can be guided along a second actuating direction B2 in order to release the clamping spring 112 from the open position.
  • the second actuating direction B2 extends parallel to the first actuating direction B1, so that the second actuating element 128 is guided in a direction parallel to the first actuating element 119.
  • the second actuating element 128 is thus guided linearly in the same way as the first actuating element 119.
  • the second actuating element 128 is arranged directly adjacent to the first actuating element 119.
  • the housing 210 has a guide shaft 212, wherein the first actuating element 119 and the second actuating element 128 are arranged and guided in this guide shaft 212.
  • the first actuating element 119 has a groove 129 on its outer peripheral surface, into which a web 130 formed on the second actuating element 128 engages. The two actuating elements 119, 128 engage with one another in a form-fitting manner via the groove 129 and the web 130.
  • the form-fitting engagement and the form-fitting guidance of the two actuating elements 119, 128 prevent the actuating elements 119, 128 from tilting or jamming relative to one another. It is also possible for the groove 129 to be formed on the second actuating element 128 and the web 130 to be formed on the first actuating element 119.

  • the two sliding surfaces 134a, 134b are each designed in the form of inclined surfaces. Due to the sliding surfaces 134a, 134b designed as inclined surfaces, the actuating fingers 131a, 131b taper towards their free end.
  • the two actuating fingers 131a, 131b are designed symmetrically to each other, so that by means of the two actuating fingers 131a, 131b a simultaneous actuation of the two holding arms 126a, 126b of the locking leg 116 is possible.
