Definitions

  • the invention relates to an actuating element for actuating a clamping spring of a connection arrangement.
  • the invention further relates to a connection arrangement with such an actuating element and a connection terminal.
  • the invention relates to an electronic device and a method for mounting a connection terminal.
  • An actuating element serves to move a clamping spring of a connection arrangement into an open position and/or a clamping position, in that the actuating element interacts with a clamping leg of the clamping spring.
  • the actuating element must fulfill several tasks. On the one hand, the actuating element must have a high level of strength in order to apply sufficient force to the clamping spring. On the other hand, the actuating element must have an insulating effect in order to enable the actuating element to be actuated by a user without risk. In addition, the actuating element must be arranged in the correct position and with a sufficiently high degree of stability in the housing of a connection terminal.
  • the object of the invention is to provide an actuating element, a connection arrangement, a connection terminal, an electronic device and a method for mounting a connection terminal, which are characterized by improved functionality.
  • the actuating element has a first body element, on which a gripping surface for actuating the actuating element is formed, and a second body element, on which at least one actuating surface for actuating the clamping spring is formed, the first body element having the second body element in front an assembly in the connection arrangement is converted into a pre-latching position.
  • the actuating element is formed from at least two components which are formed separately from one another, the first body element and the second body element. These two body parts each have a different function.
  • the actuating element is actuated by a user via the first body element, with the first body element having a grip surface for this purpose.
  • the actuating element can be actuated manually or by means of a tool, such as a screwdriver, via the gripping surface.
  • the second body member interacts directly with the clamp spring to actuate the clamp spring.
  • the second body element has at least one actuating surface, which rests directly against the clamping spring when the clamping spring is actuated.
  • the first body element on the other hand, is at a distance from the clamping spring and is not in direct contact with the clamping spring.
  • the first body member is connected to the second body member. According to the invention, a first connection of the two body elements takes place before the actuation element is installed in the connection arrangement, in particular before the actuation element is installed in a housing of a connection terminal.
  • This first connection occurs through the formation of a pre-latching position of the first body element with the second body element.
  • the first body element is thus pre-latched to the second body element prior to further assembly of the actuating element.
  • the first body element forms a latching connection with the second body element, so that the first body element is fastened to the second body element via the latching connection.
  • This latching connection can preferably be released again if required. The connection of the two body elements thus no longer takes place only when the actuating element and thus the two body elements are inserted into the connection arrangement or into the housing of the connection terminal.
  • the two body elements and thus the actuating element are arranged in the already connected state, the pre-latching position, in the connection arrangement or in the housing of the connection terminal. This facilitates the assembly and thus the handling of the actuating element and thus also the connection arrangement or the connection terminal.
  • the first body element is preferably made of a first material and the second body element is made of a second material that is different from the first material, with the second material preferably having a higher strength than the first material. Due to the two different materials of the two body elements, the properties of the two body elements can be tailored to the respective function of the two body parts can be adjusted.
  • the first body element on which the gripping surface is formed can thus have a different material property than the second body element on which the actuating surface is formed.
  • the two body elements can be formed from materials with different strengths.
  • the second body element can then be made of a higher-strength material than the first body element in order to enable stable and defined actuation of the clamping spring via the actuation surface of the second body element.
  • the first material of the first body element can have electrically insulating properties.
  • the first material can thus be an insulating material in order to form the gripping surface for operating the operating element safely for a user.
  • the first material can be a plastic material.
  • the second material of the second body element can be a metal material, which is characterized by particularly high strength and stability. The second material can then have a particularly high flexural rigidity in order to be able to ensure a defined actuation of the clamping spring via the actuation surface of the second body element of the actuation element. Since the second body element is not actuated directly by the user, it does not require any insulating properties.
  • the pre-latching position can be formed in that latching elements are formed on the first body element and/or the second body element, which latching elements can latch into corresponding openings on the first body element and/or the second body element.
  • latching elements are formed on the first body element and/or the second body element, which latching elements can latch into corresponding openings on the first body element and/or the second body element.
  • at least one latching element can be formed on the first body element and at least one opening can be formed on the second body element, and vice versa.
  • the at least one locking element can hook into the at least one corresponding opening in order to form a locking and thus the pre-locking position.
  • the first body element can have two opposite openings, into which two opposite latching elements formed on the second body element can be latched.
  • two openings and two latching elements By providing two openings and two latching elements, a particularly stable and tilt-proof latching or pre-latching position can be formed between the two body elements.
  • the two opposing openings on the second body element and the two locking elements on the first Body element are formed.
  • the first body element can each have an opening and a latching element and the second body element can each have an opening and a latching element.
  • the second body element can be designed in such a way that the second body element has at least one actuating arm and a connecting web formed transversely to the actuating arm, wherein the at least one actuating surface can be formed on the at least one actuating arm and the second body element can be connected to the first body element via the connecting web the pre-latched position can be pre-latched.
  • the second body element can thus have two functional areas that can be spatially separated from one another.
  • the first functional area can be formed on the actuating arm in the form of the actuating surface and the second functional area can be formed on the connecting web in the form of a fastening surface for pre-latching the second body element with the first body element.
  • the actuating arm preferably extends at a 90° angle to the connecting web.
  • the second body element can also have two actuating arms, which can be connected to one another via the connecting web.
  • the two actuating arms then preferably extend parallel to one another.
  • the second body element then has a U-shape.
  • An actuating surface for actuating the clamping spring is then preferably formed on each of the two actuating arms, so that the second body element then has two actuating surfaces which can actuate the clamping spring simultaneously.
  • the actuating element can also assume another function, namely holding the actuating element in a fixed position relative to the clamping spring in the open position of the clamping spring.
  • a holding contour for holding a locking leg of a clamping spring of the connection arrangement in an open position of the clamping spring can be formed on the second body element of the actuating element.
  • the clamping spring can have a latching leg which can be held on the holding contour of the second body element when the clamping spring is in the open position.
  • a stable metal-to-metal connection can be formed between the holding contour of the second body element and the latching leg of the clamping spring if the second material of the second body element is made of a metal material.
  • a connection between the first body element and the second body element can additionally or alternatively be formed in that the first body element has a fastening dome which, in the pre-latching position, can be immersed in an opening formed on the second body element.
  • the attachment dome may be in the form of a pin protruding in the direction of the second body member.
  • the opening on the second body element can have an inner diameter that is smaller than an outer diameter of the fastening dome. The fastening dome can then be fastened in the opening with a press fit. If the second body element has a connecting web, the opening is preferably formed on the connecting web.
  • the fastening element can further have a spring element.
  • the actuating element can be spring-biased via the spring element.
  • the spring element can cause the actuating element to be returned to a defined, reproducible position, in particular the starting position, when the clamping spring is transferred from the open position into the clamping position.
  • the actuating element can be spring-biased against a stop surface of the connection arrangement or against a stop surface of a connection terminal in which the connection arrangement.
  • the stop surface can be formed, for example, by the current bar of the connection arrangement. It is also possible, for example, for the stop surface to be formed by a housing surface of the housing of the connection terminal.

  • the actuating element which is made up of at least two separate components, the first body element and the second body element, is pre-latched in the connection arrangement before assembly and is therefore pre-assembled, so that the actuating element, which is formed in several pieces, can be arranged and assembled in one piece in the connection arrangement. If the actuating element has a spring element in addition to the two body elements, then the actuating element is preferably supported with its spring element on the current bar. The actuating element can thus be spring-biased against the current bar.
  • the actuating element and the clamping spring can thus form a self-contained force system when the clamping spring is in the open position, so that when the clamping spring is in the open position, the actuating element can be held in a fixed position relative to the clamping spring by the force of the clamping spring, without the actuating element having to be moved manually or must be held in this position by means of a tool.
