Definitions
- the present invention relates to a conductor connection terminal.
- Conductor connection terminals are known from the prior art, by means of which an electrical conductor can be electrically connected reversibly to an electrical contact.
- DE 10 2017 106 720 A1 describes a conductor connection terminal with a housing with a conductor receiving space for receiving an electrical conductor, accessible via a conductor insertion opening.
- a current bar for contacting a conductor inserted through the conductor insertion opening into the conductor receiving space is arranged.
- a clamping spring with a spring clamping leg is arranged in the housing, the clamping spring being actuatable between a release position and a clamping position. In the release position, an electrical conductor can be inserted and / or removed from the conductor receiving space and, in the clamping position, the spring clamp leg loads a conductor inserted into the conductor receiving space in the direction of the current bar.
- the conductor connection terminal also includes an actuating element that can be moved between a clamping position and a release position.
- the actuating element is operatively connected to the clamping spring in such a way that when the actuating element is transferred from its clamping position to its release position, the spring clamping leg is subjected to force by the actuating element and the clamping spring is transferred from its clamping position to its release position.
- the conductor connection terminal described in DE 10 2017 106 720 A1 thus ensures that an inserted electrical conductor is clamped or released in that the actuation element can be moved along an actuation direction, this actuation direction being parallel to the conductor insertion direction of the electrical conductor in the conductor receiving space .
- the Actuate transmission element first engages relatively far inside, at a point near the flexure, on the spring clamp leg of the clamp spring.
- the present invention is therefore based on the object of providing a conductor connection terminal which is easier to handle.
- a conductor connection terminal comprising a housing with a conductor receiving space for receiving an electrical conductor, accessible via a conductor insertion opening, the electrical conductor being insertable into the conductor receiving space in a conductor insertion direction.
- the conductor connection terminal comprises a current bar arranged in the conductor receiving space for contacting a conductor inserted into the conductor receiving space via the conductor insertion opening.
- the conductor connection terminal comprises a clamping spring arranged in the housing with a spring clamping leg, wherein the clamping spring can be actuated between a release position and a clamping position, wherein in the release position an electrical conductor can be inserted and / or removed from the conductor receiving space, and the spring clamping leg in the clamping position force is applied to a conductor introduced into the conductor receiving space in the direction of the current bar.
- the conductor connection terminal comprises an actuation element which can be displaced along an actuation direction between a clamping position and a release position, the actuation element being in operative connection with the clamping spring in such a way that, when the actuation element is transferred from its clamping position to its release position, the spring clamping leg is actuated by the actuation element force is applied and the clamping spring is transferred from its clamping position to its release position.
- the conductor connection terminal according to the invention is characterized in that the actuation direction is formed at an angle greater than 0 ° to the conductor insertion direction, and that when the actuating element is transferred from its clamping position to its release position, at least one skid of the spring clamp leg is acted upon by the actuating element and, during the transfer of the clamping spring from its clamping position to their release position, the spring clamping leg slides with the skid along a pressure surface of the actuating element facing the clamping spring.
- the actuation of the actuating element can be handled more easily by means of the conductor connection terminal according to the invention. Due to the fact that the actuation direction and the conductor insertion direction are no longer parallel to one another, but are at an angle deviating from 0 °, and the fact that the spring clamping leg has an extra skid that slides along the pressure surface of the actuation element, the point of application of the actuation element migrates the spring clamp leg no longer along the spring clamp leg. Rather, it is ensured that the actuating element acts on the spring clamp leg at a constant point of application during an actuation process. This point of application is the at least one skid of the spring clamp leg.
- the pressure surface of the actuating element represents a kind of running contour or sliding or contact contour, which ensures that the actuating element is continuously in contact with the same contact section of the spring clamp leg, namely with the skid of the spring clamp leg.
- the pressure surface of the actuating element can accordingly also be called a running, sliding or contact surface.
- the process of transferring the actuating element from its clamping position to its release position is meant in the present case.
- the clamping spring is moved from its clamping position to its release position by the spring clamp legs or the clamping spring being closed and a possibly clamped electrical conductor is released.
- the housing is preferably formed from an electrically insulating material.
- the housing can also be referred to as an insulating housing.
- the electrical conductor can be inserted or pushed into the conductor receiving space in a conductor insertion direction via the conductor insertion opening.
- the current bar has electrically conductive areas at least in one contact area.
- the current bar is preferably formed from an electrically conductive material, for example a metal.
- the current bar is also electrically / galvanically connected to a further electricalmaschineein direction, for example an electrical contact pin and / or an electrical contact socket.
- the actuating element can also be referred to as an actuating lever or pusher.
- the actuating element can preferably have a handling section (or also referred to as operating section) and a pressure section (or also referred to as pusher section), the pressure surface then being provided on the pressure section, specifically on the side of the pressure section facing the clamping spring.
- the pressure surface of the actuating element (and thus also the pressure section) is preferably always in contact with the spring clamping leg of the clamping spring. Consequently, the pressure surface or the pressure section of the actuating element is then in contact with the spring clamping leg of the clamping spring both in the release position and in the clamping position of the clamping spring.
- the actuating element is preferably set up in such a way that pressing the actuating element in the direction of actuation, i.e. applying force to the actuating element in the direction of the actuating direction in the form of exerting an actuating force, moves the actuating element in the direction of the clamping spring.
- the spring clamp leg is closed, as a result of which the Klemmfe is transferred from its clamping position to its release position.
- a flexible joint of the clamping spring is preferably deformed by moving its clamping position into its release position in such a way that a contact leg and the spring clamping leg of the clamping spring enclose a smaller angle with one another in their release position than in the clamping position of the clamping spring.
- the clamping spring therefore preferably has the spring clamping leg, which represents the movable leg of the clamping spring, and also a fixed, non-movable contact leg, and also a bending joint which connects the spring clamping leg and the contact leg to one another and around which the spring clamping leg is when opened or Closing the clamping spring turns.
- the angle at which the actuation direction is formed in relation to the conductor insertion direction is to be understood as the angle at which the direction defined by the actuation direction Axis is on the axis defined by the conductor insertion direction. In the prior art solutions in which the actuation direction runs parallel to the conductor insertion direction, this angle is 0 °.
- the actuation direction is formed at an angle between 45 ° and 135 ° to the conductor insertion direction (R), preferably the actuation direction is formed essentially perpendicular to the conductor insertion direction.
- the actuating element has at least one first actuating arm and the pressure surface of the actuating element is formed on a side of the first actuating arm facing the clamping spring.
- the actuating element can furthermore have a second actuating arm and the pressure surface of the actuating element can also be formed on a side of the second actuating arm facing the clamping spring.
- This second actuating arm can be provided in addition to the first actuating arm.
- an easy-to-manufacture and weight-saving embodiment of the conductor connection terminal can be implemented, since the special contour of the pressure surface or pressure surfaces adapted to the skid or skid is only locally on the actuation arm or the operating arms must be trained.
- the conductor connection terminal can thus be made more compact, since a free space lying between the actuating arms is available as space for an electrical conductor to be inserted and, in particular, the actuating element can be made more compact.
- the skid of the spring clamp leg can be arranged on an outer end of the spring clamp leg facing away from a bending joint of the clamping spring.
- an embodiment is achieved which requires a particularly low expenditure of force during the actuation process of the actuating element, since the skid that is in contact with the pressure surface of the actuating element is provided at an outer point of the spring clamping leg at which the necessary actuating force to move the spring clamping leg is lower .
- the point of application on the clamping spring is therefore as far away as possible from the flexible joint.
- the spring clamp leg can have a bent extension directed away from the pressure surface of the actuating element, facing away from a bending joint of the Klemmfe and adjoining the skid. This prevents the skid from jamming with the pressure surface or even digging into it. The effort required to actuate the actuating element is thus further reduced, since an increased actuating force would be required for a sliding skid jammed in the pressure surface to slide off.
- a curved extension can then be provided on each of the runners.
- the spring clamp leg can have two skids on the side at its end facing the actuating element and a clamping edge set back in relation to the two skids in the direction of a bending joint of the clamping spring.
- the clamping edge can be arranged between tween the skids. In the clamping position of the clamping spring, the clamping edge ensures that an electrical conductor introduced into the conductor receiving space is securely clamped. Because the clamping edge is set back, a compact design is also made possible, and it is achieved that the electrical conductor in the release position of the clamping spring can be removed again in a simple manner from the conductor receiving space and thus the conductor connection terminal.
- the pressure surface of the actuating element can have a latching section, the skid rests on the latching section in a state when the actuating element is in its release position, the clamping spring is in its clamping position and no electrical conductor is inserted into the conductor receiving space is.
- the latching section is regularly the section of the pressure surface facing the conductor insertion direction. The latching section thus generally corresponds to the starting section from which the skid of the clamping spring begins to slide along the pressure surface during an actuation process in order to be moved from its clamping position into its release position.
- the pressure surface of the actuating element can move from the latching section to an end section arranged opposite the latching section Pressure surface be designed to run inclined in the direction of actuation. This ensures effective guidance of the skid along the pressure surface and thus a low expenditure of force during the actuation process of the actuation element.
- the inclination of the pressure surface can be adapted to the trajectory or trajectory of the skid, which it covers during a closing or opening process of the clamping spring, that is, during the transition from the clamping position to the release position.
- At least one inner guide wall can be provided at one end of the actuating element viewed in the actuating direction, the inner guide wall being in operative connection with the skid of the spring clamp leg in such a way that a sideways movement of the actuating element in a direction perpendicular and perpendicular to the actuating direction standing on the inner guide wall, outer direction is prevented by the inner guide wall hitting the skid.
- the clamping spring is accordingly guided securely along the pressure surface on the one hand and also securely laterally guided along the inner guide wall on the other hand.
- two inner guide walls can also be provided, for example when designing two pressure surfaces and two skids, so that both skids are safely guided laterally.
- the guide wall contour of the inner guide wall, seen in the actuation direction can be adapted to the clamping edge of the clamping spring, so that a free space is created for the clamping edge, which is necessary for an undisturbed course of the rotational movement of the spring clamping leg with simultaneous linear movement of the actuating element.
- At least one outer guide wall can be provided at one end of the actuating element viewed in the actuating direction, the outer guide wall being in operative connection with the spring clamping leg in such a way that at least in the release position of the clamping spring and the release position of the actuation element a Sideways movement of the actuating element in an inner direction running perpendicular to the actuating direction and perpendicular to the outer guide wall is prevented by the outer guide wall striking the spring clamping leg.
- an operationally safe and less error-prone conductor connection terminal is provided, as a Slipping or knocking out of the actuating element or its side wall inward, for example, is prevented during an application of force in an actuation process.
- This is particularly advantageous in the case of conductor connection terminals comprising a housing with an open side wall.
- the clamping spring is therefore on the one hand safely guided along the pressure surface and on the other hand also safely guided laterally along the outer guide wall.
- Two outer guide walls can preferably also be provided, for example in the case of the configuration of two pressure surfaces and two skids, so that both skids are safely guided laterally.
- the outer side wall can also be designed in such a way that the sideways movement of the actuating element is prevented even in the clamping position of the clamping spring and the clamping position of the actuating element.
- the outer guide wall can be designed as a continuation of the pressure surface extending in the actuation direction, the outer guide wall engaging in a lateral recess of the spring clamp leg to establish the operative connection with the spring clamp leg.

- a conductor connection terminal 1 is Darge provides.
- the conductor connection terminal 1 has a housing 10 which is formed from an electrically insulating material or at least has an electrically insulating material.
- the housing 10 has a conductor insertion opening 11 via which a conductor receiving space 12 of the housing 10 is accessible.
- An electrical conductor L (only shown in FIG. 1A) can be introduced into the conductor receiving space 12 via the conductor insertion opening 11 by the electrical conductor L being introduced or pushed into the conductor receiving space 12 in a conductor insertion direction R.
- the conductor connection terminal 1 also has a current bar 20, which is arranged in the conductor receiving space 12 and is designed for contacting an electrical conductor L introduced into the conductor receiving space 12 via the conductor insertion opening 11.
- the current bar 20 is made from an electrically conductive material, for example from a sheet steel.
- the current bar 20 is also electrically connected to a further electrical contact device, for example an electrical contact pin and / or an electrical contact socket, the further electrical contact device not being shown in the figures.
- a clamping spring 30 is also arranged, which has a contact leg 31 and a spring clamping leg 32, the contact leg 31 and the spring clamping leg 32 are connected via a flexure 33.
- the clamping spring 30 can assume various positions by changing the position of the movable spring clamping leg 32. Thus, the clamping spring 30 can be brought into the clamping position shown in FIG. 1A or into the release position shown in FIG. 1C.
- the clamping spring 30 can be actuated between its clamping position and its release position.
- An actuation process accordingly describes the process of how the clamping spring 30 is first brought from its clamping position (FIG. 1A) into its release position (FIG. 1C).
- FIGS. 2A, 2B and 2C the conductor connection terminal 1 can be seen from the corresponding representations of FIGS. 1A, 1B and 1C in a perspective view, with a renewed representation of the housing 10 for the sake of clarity was waived.
- FIGS. 1A, 1B and 1C or FIGS. 2A, 2B and 2C three different phases of the actuation process described are shown.
- FIG. 1A and Fig. 2A the beginning of an actuation process is shown, the clamping spring 30 being in its clamping position.
- the spring clamping leg 32 of the clamping spring 30 acts on an electrical conductor L introduced into the conductor receiving space 12 (in FIG. 1A the electrical conductor L is not shown inserted into the conductor receiving space 12).
- the introduced electrical conductor L is pressed in the direction of the current bar 20, so that a safe Contact between the inserted electrical conductor L and the current bar 20 is ensured.
- the conductor connection terminal 1 is shown during an actuation process, that is, neither at the beginning nor at the end of the actuation process. Accordingly, the clamping spring 30 is in a position between its clamping position and its release position. Finally, the conductor connection terminal 1 is shown in FIG. 1C or FIG. 2C at the end of an actuation process. At the end of the actuation process, the clamping spring 30 is in its release position. In the release position, an electrical conductor L can be freely inserted into and / or removed from the conductor receiving space 12 without any particular resistance. In the release position of the clamping spring 30, the inserted electrical conductor L is no longer subjected to force by the spring clamping leg 32 and is therefore no longer pressed against the current bar 20.
- the described transition of the clamping spring 30 from its clamping position into its release position is carried out by actuating an actuating element 40, for example by hand or by means of a tool.
- the actuating element 40 is displaced along an actuating direction B, i.e. the actuating element 40 is pressed down.
- the actuating element is displaced from the clamping position shown in FIG. 1A or FIG. 2A into the release position shown in FIG. 1C or FIG. 2C.
- the actuating element 40 presses on the spring clamping leg 32 of the clamping spring and thus closes the clamping spring 30, whereby the clamping spring 30 is brought from its clamping position into its release position.
- the spring clamp leg 32 includes a larger angle with the contact leg 31 in the clamping position than in the release position.
- the actuating element 40 exerts an actuating force in the direction of the spring clamp leg 32 of the clamping spring 30 during an actuation process and thus closes the clamping spring 30.
- this actuating force is exerted by a pressure surface 41 of the actuating element 40 on a slide 34 of the spring clamp leg 32.
- the skid 34 is in contact with the pressure surface 41 of the actuating element 40 facing the clamping spring 30.
- the skid 34 slides along the pressure surface 41. This ensures that the actuating element 40 is always at the same point on the spring clamp leg 32 of the clamping spring 30 attacks and thus the effort required for actuation is low.
- This is the Skid 34 of the spring clamp leg 32 is also arranged on an outer end of the spring clamp leg 32 facing away from the bending joint 33 of the clamping spring 30.
- the coordination of the contour of the actuating element 40 seen in the direction of the clamping spring 30, i.e. the design of the pressure surface 41, ensures that the clamping spring 30 is always contacted and actuated or pressed by the actuating element 40 at the same point of application.
- the expenditure of force is advantageously minimized in that the actuation direction B is essentially perpendicular to the conductor insertion direction R.
- the clamping spring 30 is oriented essentially in the same direction as the conductor insertion direction R. In a state inserted into the conductor receiving space 12, the electrical conductor L extends almost parallel to a spring clamping leg 32 from the clamping spring 30 when the latter is in its clamping position.
- the actuation element 40 can contact the spring clamp leg 32 at a point of application further away from the bending joint 33, so that a lower actuation force is necessary than in the prior art, according to which of the spring clamping legs 32 would initially be actuated close to the flexible joint 33.
- the actuation direction B is formed at an angle greater than 0 ° to the conductor insertion direction R, that is, not parallel to the conductor insertion direction R.
- the actuation direction B could, in contrast to the illustrated and insofar preferred exemplary embodiment, also be designed, for example, instead of at right angles to the conductor insertion direction R at an angle between 45 ° and 135 ° to the conductor insertion direction R other than 90 °.
- the actuating element 40 can be fixed or determined both in its clamping position and in its release position. Accordingly, no permanent application of force or actuation of the actuating element 40 in the direction of the actuation direction B is necessary in order to allow the actuating element 40 to remain in its release position, for example.
- the pressure surface 41 of the actuating element 40 is designed to run inclined from a latching section 45 towards an oppositely arranged end section 46 in the direction of the actuating direction B (see Fig. 2A and the one shown in Fig. 1A, Fig. 1B and Fig. 1C).
- the end portion 46 is in the Side views of FIGS. 1A, 1B and 1C arranged lower than the latching section 45 (see also FIG. 2A). This ensures that the pressure surface 41 is continuously in contact with the skid 34 at the same point of application.
- the skid 34 also rests against the latching section 45 in a state when the actuating element 40 is in its release position, the clamping spring 30 is in its clamping position and no electrical conductor L is inserted into the conductor receiving space 12, as in FIGS. Fig. 2A can be seen.
- a first actuating arm is located at the end of the actuating element 40 facing the clamping spring 30 43 and a second actuating arm 44 are provided.
- the pressure surface 41 or 42 of the actuation element 40 is formed on a side of the first actuation arm 43 or the second actuation arm 44 facing the clamping spring 30.
- a free space is formed between the first actuating arm 43 and the second actuating arm 44. This free space prevents the electrical conductor L to be inserted into the conductor receptacle 12 and the first actuating arm 43 or the second actuating arm 44 from blocking one another.
- two pressure surfaces 41 and 42 are provided for each actuating element 40, and the spring clamping leg 32 accordingly has two skids 34 laterally at its end facing the actuating element 40.
- the two skids 34 are each in contact with the pressure surface 41 and 42 assigned to them. All of the features that were previously described in connection with the printing surface 41 also apply to the printing surface 42.
- the spring clamping leg 32 has a clamping edge 37 that is offset back in relation to the two runners 34 in the direction of the bending joint 33 of the clamping spring 30.
- the clamping edge 37 clamps the electrical conductor L introduced into the conductor receiving space 12 in the clamping position of the clamping spring 30, i.e. the inserted electrical conductor L is contacted via the clamping edge 37 and subjected to force and thus pressed in the direction of the current bar 20.
- the clamping edge 37 is arranged between the two skids 34.
- the spring clamping limb 32 faces away from the bending joint 33 of the clamping spring 30 and adjoins the respective skid 34 with one of the pressure surface 41 or 42 of the actuating element 40 directed away, curved extension 35 or 36 (see Fig. 2A, 2B, 2C and 4B).
- the projections 35, 36 prevent the skid 34 or the spring clamp leg 32 from digging into the pressure surfaces 41 or 42 of the actuating element 40 or from being able to get caught therewith. A safe sliding of the skids 34 on the pressure surfaces 41 and 42 is guaranteed.
- At least one inner guide wall 47_1 or 47_2 is provided at an end of the actuating element 40 viewed in the actuating direction B.
- This inner guide wall 47_1 or 47_2 is in operative connection with the corresponding, associated skid 34 of the spring clamp leg 32 that a sideways movement of the actuating element 40 in an outer direction perpendicular to the actuating direction B and perpendicular to the inner guide wall 47_1 or 47_2 A1 or A2 is prevented by the inner guide wall 47_1 or 47_2 hitting the skid 34.
- the Gleitku fen 34 and thus the clamping spring 30 are not only guided safely along the pressure surfaces 41 and 42, but also safely laterally along the inner guide wall 47_1 and 47_2. This is particularly advantageous in the case of the conductor connection terminals 1 shown, comprising a housing 10 with an open side wall.
- a guide wall contour 49 of the inner guide wall 47_1 or 47_2, seen in actuation direction B, can be adapted to the clamping edge 37 of the clamping spring 30 so that a free space is created for the clamping edge 30 (FIGS. 5A and 5B). This free space is necessary for an undisturbed course of the rotational movement of the spring clamp leg 32 with simultaneous linear movement of the actuating element 40.
- At least one outer guide wall 48_1 is also provided at an end of the actuating element 40 viewed in the actuating direction.
- This outer guide wall 48_1 is in operative connection with the spring clamp leg 32 in such a way that at least in the release position of the clamping spring 30 and the release position of the actuating element 40, a sideways movement of the actuating element 40 in a direction perpendicular to the actuating direction B and perpendicular to the outer guide wall 48_1, inner direction 11 is prevented by the outer guide wall 48_1 hitting the spring clamp leg 32.
- further lateral guidance of the skids 34 namely on the outer guide wall 48_1, is again ensured.
- the outer guide wall 48_1 is designed as a continuation of the pressure surface 41 or 42 running in the actuation direction B.
- the outer guide wall 48_1 engages in a lateral recess 38 of the spring clamp leg 32 to establish the operative connection with the spring clamp leg 32 and thus prevents the actuating element 40 from swinging out laterally in the inner direction 11.
- the described lateral guidance through the outer guide wall 48_1 can also already take place in the clamping position of the clamping spring 30 and the clamping position of the actuating element 40, for example by engaging the outer guide wall 48_1 in the lateral recess 38 of the spring clamp leg 32 already in the clamping position of the Clamping spring 30 and the clamping position of the actuating element 40.
