Definitions

  • the invention relates to a connection terminal for connecting an electrical conductor, with 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 in a conductor connection space formed between the current bar and the clamping spring, and an actuating element , which is slidably mounted on the housing, wherein a clamping leg of the clamping spring can be actuated to transfer the clamping leg from a clamping position to an open position by means of the actuating element, whereby, viewed along an actuation direction of the actuating element, below a section of the current bar against which the conductor passes through Clamping spring is clamped, a guide element for supporting the actuating element and / or a guide element for supporting the clamping spring is provided.
  • connection terminal is, for example, from CN 202 564 566 U and the US 2018/166802 A1 known.
  • the actuating element of such a connection terminal therefore serves, on the one hand, to actuate the clamping spring in order to release the conductor connection space for inserting the conductor to be connected.
  • the actuating element delimits the conductor connection space at least in sections. For both functions, it is important that the actuating element reliably assumes its intended position both in the clamping position and in the open position.
  • the actuating element is partially deformed or deflected from its intended position due to excessive force in the open position, an undesirable gap can arise between the housing and the actuating element, into which a conductor end of the conductor to be connected can be accidentally inserted, so that it In the clamping position, there may not be an electrically conductive contact between the current bar and the electrical conductor to be connected.
  • such a deformation or deflection of the actuating element can cause the actuating element to slide off the clamping leg of the clamping spring, so that the actuating element is no longer in engagement with the clamping leg of the clamping spring.
  • the case can occur here that the clamping leg is already in place before Insertion of the electrical conductor to be connected snaps back into the clamping position, so that the conductor can no longer be inserted into the conductor connection space.
  • the invention is therefore based on the object of providing a connecting terminal and an electronic device which enable reliable actuation of the clamping leg by the actuating element.
  • connection terminal is characterized in that the guide element for supporting the actuating element has a first guide surface, which effects a support of the actuating element against transverse displacement along a first direction, and the guide element for supporting the actuating element has a second guide surface, which provides a support of the actuating element against transverse displacement along a second direction that is different from the first direction.
  • the guide element for supporting the actuating element ensures that the actuating element is not deformed or deflected during the transfer from the clamping position to the open position, and vice versa, and remains in reliable contact with the clamping leg of the clamping spring.
  • the guide element for supporting the clamping spring ensures that the clamping spring is not deformed or deflected, particularly during actuation of the clamping spring by means of the actuating element, and remains reliably in the desired position within the housing.
  • the connection terminal can have the guide element for supporting the actuating element and the guide element for supporting the clamping spring. But it is also possible for the connection terminal to have only one of the two guide elements.
  • the actuating element limits the conductor connection space at least in sections, in particular at least on two sides.
  • the guide element additionally supports the actuating element ensures that no gaps formed by a deformation or deflection of the actuating element can arise between the actuating element and the housing, which could lead to incorrect assembly of the electrical conductor to be connected.
  • the guide element for supporting the actuating element and/or guide element for supporting the clamping spring can be an integral part of the housing. In this way, the respective guide element can be integrated cost-effectively into the shape of the housing.
  • the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring and/or the housing can have an electrically insulating plastic or can consist of an electrically insulating plastic.
  • the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring can, for example, be part of a side wall of the housing of the connecting terminal. Consequently, the guide element can be compactly integrated into the housing of the connection terminal.
  • the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring is provided as a separate component and is connected to the housing of the connecting terminal.
  • the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring can have been encapsulated with a plastic of the housing, so that there is a positive connection between the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring and the housing of the connecting terminal can be formed.
  • the guide element for supporting the actuating element and/or the guide element for supporting the clamping spring is detachably connected to the housing of the connecting terminal.
  • the guide element for supporting the actuating element can be a web which surrounds a section of the actuating element. Accordingly, deflection of the actuating element can be positively prevented by the web.
  • the guide element for supporting the clamping spring can also be a web which laterally supports a section of a holding leg of the clamping spring.
  • the guide element for supporting the clamping spring can prevent lateral movement, in particular of the holding leg of the clamping spring, when the clamping leg of the clamping spring is transferred into the clamping position and into the open position. Even in the clamped state of a conductor, a secure fit of the clamping spring can be ensured by means of the guide element and thus tilting of the clamping spring can be prevented.
  • the guide element for supporting the actuating element can be part of a linear guide, which only enables a purely translational movement of the actuating element from a first position to a second position, so that the linear guide can deprive the actuating element of three rotational and two translational degrees of freedom .
  • a linear guide can, for example, be specified in a purely form-fitting manner by a geometry of the housing of the connecting terminal in which the actuating element is accommodated.
  • the housing can have a shaft along which the actuating element can be moved, the guide element for supporting the actuating element can serve as additional support against deflection or deformation of the actuating element.

  • the guide element for supporting the actuating element has a second guide surface, which supports the actuating element against transverse displacement along a second direction that is different from the first direction. If we are talking about a transverse displacement in the present case, this is in particular a displacement transverse to the actuation direction of the actuating element, along which the actuating element carries out a translational movement in order to move the clamping leg from its clamping position into its open position, and vice versa.

  • At least one actuating arm can have at least one guide web, which can be arranged on a side of the actuating arm facing away from the conductor connection space and/or can slide along the guide element to support the actuating element when the actuating element is actuated.
  • the guide web can be used for the defined contact of the actuating arm on the guide element.

  • the current bar can penetrate the actuating element, wherein the section of the current bar against which the conductor is clamped by the clamping spring can be arranged between the at least one actuating arm and a second actuating arm of the actuating element. In this way, the current bar together with the actuating element can be compactly integrated into the housing of the connection terminal.
  • the current bar can have recesses against which the actuating arms of the actuating element can rest, so that the current bar can also provide guidance for the actuating element.
  • the actuation element can have an asymmetrical shape, with the shape of the at least one actuation arm different from the shape of the second actuation arm.
