Definitions

  • the invention is based on a clamping spring according to the preamble of claim 1.
  • the invention also relates to a conductor connection terminal with a clamping spring.
  • Conductor connection terminals and their spring clips are, for example, from the WO 2016/102322 A1 known. Such conductor connection terminals and their spring clips differ from electrical plug connectors, for example, in the significantly higher clamping force of the clamping spring, since, unlike a plug connector, a conductor connection terminal is not designed for frequent mating and detaching processes like electrical plug connectors.
  • the object of the invention is to find a solution that is inexpensive in terms of production and cost for the field of conductor connection technology by means of spring force clamping in order to increase the conductor holding force of such a conductor connection terminal and its clamping spring.
  • clamping spring according to claim 1.
  • the clamping leg has at least one bead embossed in the material of the clamping leg, which does not extend to the free end of the clamping leg, but ends in front of it.
  • the bead can be formed, for example, as an embossing or as any other type of recess in the clamping leg.
  • the bead increases the spring stiffness of the clamping leg, in particular in a possibly existing bending area of the clamping leg. In this way, the conductor holding force of the clamping spring and a conductor connecting terminal formed therewith can be easily and can be increased inexpensively without increasing their size or increasing the weight and material requirements for the clamping spring.
  • the conductor holding force is the force that is effective against the electrical conductor being pulled out of the terminal point.
  • the clamping leg can have a clamping edge for clamping the electrical conductor.
  • the mechanical fixing and electrical contacting of the electrical conductor can be further improved and the conductor holding force can also be increased.
  • the clamping leg has a first area adjoining the spring arch and a second area ending with the free end of the clamping leg, the first area over a bending area of the clamping leg in which the clamping leg has a curved shape having, is connected to the second region.
  • the clamping spring can for example be designed such that the first area of the clamping leg adjoining the spring arch extends at least substantially parallel to the area of the contact leg adjoining the spring arch, at least when the clamping spring is relaxed or the clamping spring is deflected. Due to the bending area, the second area of the clamping leg can extend further bent away from the contact leg, i.e. the second area of the clamping leg forms a larger angle to the contact leg than the first area.
  • the clamping leg has the at least one bead embossed in the material of the clamping leg, at least in the bending area. It was found that in the case of a clamping spring in which the clamping leg has at least one bending area, an increase in the spring stiffness in this critical area, ie the bending area, can be increased by a modification that is relatively easy to implement from a manufacturing point of view, namely an embossed bead, thereby increasing the section modulus.
  • the bead extends from the bending area into the first area and / or into the second area of the clamping leg.
  • the bead can for example be arranged symmetrically with respect to the first and the second area, i.e. it can extend from the bending area into the first and the second area of the same length. It is advantageous if the bead does not extend to the spring arch, but ends in front of it. Alternatively, the bead can also extend into the further spring arch.
  • the clamping leg has a further bending area between the first and the second area, in which the clamping leg has a curved shape.
  • a clamping spring which is even better adapted to the respective requirements of the conductor connection terminal with regard to the shape can be realized.
  • the bending area can be bent in the same bending direction (same bending direction) as the further bending area, or in the opposite bending direction.
  • the bead can in particular extend from the bending area to the further bending area.
  • the bending area can also be viewed as a common bending area together with the further bending area, so that the bead embossed in the material of the clamping leg can be located in this common bending area, that is, the bead can be arranged both in the bending area and in the further bending area.
  • the bead does not extend into the further bending area. Accordingly, the bead is comparatively short so that it ends before the wider bending area. Alternatively, the bead can also extend into the wider bending area.
  • the bead has a curved contour following the curved course of the clamping leg in the bending area.
  • the bead thus follows the contour of the geometry of the clamping spring at least in the area of the clamping leg in which the bead is arranged.
  • the bead thus has a surface that runs at least approximately parallel to the curved shape of the clamping leg in the bending area.
  • the bead bridges the bending area in a straight line. This allows a particularly simple production of the bead.
  • an angle formed by the bending area between the first and the second area of the clamping leg is at least 10 degrees or at least 15 degrees.
  • the angle can also assume larger values, for example at least 30 degrees or at least 40 degrees. The angle is thus formed between the second section of the clamping leg and an extension of the first area of the clamping leg.
  • the material of the clamping leg in the area of the bead is deformed into an indentation on an embossed side of the clamping leg and into a bulge on the side opposite the embossed side. Accordingly, the material of the clamping leg is pressed in in the area of the bead on the embossed side and protrudes slightly on the opposite side.
  • the indentation thus forms a depression on the embossing side of the clamping leg, for example in the form of a concave indentation.
  • the bulge thus forms a protruding elevation on the side of the clamping leg opposite the embossing side, for example in the form of a convex bulge.
  • the convex side of the bending area forms the embossing side.
  • the embossing side can in particular be the side of the clamping leg which is opposite the contact leg. In this way, the increase in the spring stiffness of the clamping leg can be further optimized.
  • the height of the bulge is less than the material thickness of the clamping leg in the bending area. Accordingly, the deformation of the material of the clamping leg by the bead is comparatively small, so that undesired material weakening of the clamping leg due to excessive deformation levels can be avoided.
  • the length of the clamping leg extends from the spring bow to the free end.
  • the clamping leg is formed from a spring-hard sheet metal material, the material thickness of which also forms the thickness of the clamping leg (thickness dimension).
  • the width of the clamping leg is the dimension that extends orthogonally to the thickness dimension and length dimension of the clamping leg. The height of the bulge is measured in the direction of the thickness dimension of the clamping leg, starting from the adjacent surface area of the clamping leg that is not deformed by the bead on the side opposite the embossing side.
  • the bead does not extend over the entire width of the clamping leg.
  • the bead can be formed within the width of the clamping leg so that it does not extend as far as the left and right lateral edges in the direction of the width dimension of the clamping leg.
  • the length of the bead, measured in the longitudinal direction of the clamping leg can for example be one to five times as large as the width of the bead.
  • the clamping leg has at least one taper, by means of which the width of the clamping leg is reduced from the spring bow in the direction of the free end of the clamping leg, the bead being arranged in the area of the clamping leg which has the taper .
  • an area of the clamping leg that is particularly critical with regard to the spring stiffness can be reinforced by the bead.
  • the taper can be designed as a continuous taper, for example with a linear or non-linear transition from a wide area of the clamping leg to a narrower area of the clamping leg. As explained, the narrower area of the clamping leg is arranged closer to the free end of the clamping leg than the wider area of the clamping leg.
  • the taper can also be designed as a step-like reduction in width. This has the particular advantage that an actuating element for actuating the clamping spring, e.g. an actuating lever, an actuating lever or some other tool, can act on the at least one step formed on the side of the clamping leg in this way. The step-like shoulder formed in this way can thus be used as an actuating tab for the clamping spring.
  • the taper can be present on one or both sides of the clamping leg. Accordingly, the step-like reduction in width can also be present on one side or on both sides of the clamping leg. By arranging the step-like reduction in width on both sides, in particular a two-sided, symmetrical application of force to the clamping leg can be applied to open the clamping point.
  • the bead has its greatest length dimension in the direction of the longitudinal extension of the clamping leg.
  • the main direction of extent of the bead thus corresponds to Direction of the longitudinal extension of the clamping leg.
  • a conductor connection terminal for connecting an electrical conductor by means of spring force clamping having at least one clamping spring, a busbar and an insulating material housing which at least predominantly surrounds the clamping spring and the busbar, the clamping spring being designed as a clamping spring of the type explained above .
  • the conductor connection terminal has a pivotable actuating lever for manual actuation of the clamping leg of the clamping spring.
  • the actuating lever is used to open and / or close a clamping point formed between the clamping leg and the busbar for clamping the electrical conductor.
  • the clamping point formed between the clamping leg and the busbar can thus be opened or closed at the discretion of the user. This allows simple and ergonomic operation of the conductor connection terminal. No additional tools are required to operate the clamping leg.
  • the actuating lever can have a left and a right side wall.
  • a conductor receiving space for receiving the electrical conductor clamped at the clamping point can be arranged between the left and the right side cheek. This enables the implementation of a particularly compact conductor connection terminal, since the installation space that is partly used by the actuating lever can also be used for the arrangement of the electrical conductor.
  • the electrical conductor can thus be inserted or pushed through between the left and right side panels of the actuating lever in order to be clamped in the conductor connection terminal.
  • the actuating lever can have at least one actuating element that acts mechanically on the clamping limb to actuate the clamping limb, for example an actuating contour.
  • the actuating element then acts on an actuating tab of the clamping leg.
  • the actuating tab of the clamping leg can be arranged in the wider area of the clamping leg, in particular in the case of a tapering clamping leg.
  • the indefinite term “a” is not to be understood as a numerical word. If, for example, a component is mentioned, this is to be interpreted in the sense of "at least one component”. As far as angles are given in degrees, these refer to a circle of 360 degrees (360 °).
  • the clamping spring 4 has a contact leg 40, a spring bow 42 adjoining the contact leg 40 and a clamping leg 43 adjoining the spring bow 42.
  • the contact leg 40 is used to fix the clamping spring 4 in the conductor connection terminal 1, e.g. on a busbar 3, an insulating material housing 2 or another component of the conductor connection terminal 1 that is suitable for fastening the clamping spring 4.
  • the contact leg 40 has a curved fixing section 437 at its free end. Via the fixing section 437, the contact leg 40 can be suspended, for example, in a cutout in a busbar 3.
  • the contact leg 40 can be designed in such a way that it tapers from the spring bow 42 towards its free end, for example tapers once or several times in steps. In the exemplary embodiment, it is shown that the contact leg 40 becomes narrower in the transition to a section 41.
  • the fixing section 437 can be made even narrower than the section 41.
  • the clamping leg 43 has a first area 431 which adjoins the spring bow 43.
  • the clamping leg 43 also has a second region 432 which ends with the free end of the clamping leg 43.
  • a clamping edge 436 can be present at the free end of the clamping leg 43.
  • the clamping leg 43 merges from the first area 431 via one or more bending areas 433, 434 into the second area 432. Two bending areas 433, 434 are shown by way of example.
  • the clamping leg 43 has an intermediate area 435 between the bending areas 433, 434.
  • the clamping leg 43 can, as shown, also taper towards the free end, i.e. the width of the clamping leg 43 decreases from the spring bow 42 towards the free end.
  • the width of the clamping leg can be reduced, for example, from dimension B1 to B2.
  • the clamping leg 43 can have a taper 438, 439, through which the reduction in width takes place continuously or, as shown in the exemplary embodiment, in steps. It is shown by way of example that a taper 438, 439 is present on both sides of the clamping leg 43, i.e. on the left and right of the narrower second region 432.
  • the wider material areas of the clamping leg adjoining the taper 438, 439 can be used, for example, as actuating tabs for actuating the clamping leg 43 by an actuating lever 5, an actuating lever or an actuating tool.
  • the clamping leg 43 has, at least in the bending area 433, a bead 7 embossed into the material of the clamping leg 43.
  • the bead 7 serves to increase the spring stiffness of the clamping leg 43.
  • the bead 7 extends from the bending area 433 a little into the second area 432.
  • the bead 7 can extend a little from the bending area 433 into the first area 431, or at least into the intermediate area 435.
  • the bead 7 can end before the further bending area 434.

  • the length L of the bead 7 can advantageously be greater than the width B3 of the bead 7, e.g. one to five times as long as the width B3.
  • the height H of the bead 7 can advantageously be smaller than the material thickness D of the clamping leg 43, in particular the material thickness of the clamping leg 43 in the bending area 433.

  • an actuating element 56 of the actuating lever 5 can be moved, which presses against the clamping leg 43 in the area of the respective taper 438, 439 and thereby deflects the clamping leg 43 towards the contact leg 40.
  • the clamping edge 436 is thereby moved away from the busbar 3, so that the clamping point 30 is opened.
  • FIGS. 1 to 5 show an embodiment of the clamping spring 4 in which the bead 7 is designed as a bead following the contour of the clamping spring 4. Since the bead 7 extends beyond the bending area 433 on both sides, it is accordingly also curved in a side view.

It becomes clear that the side wall sections 52, 53 taper from the pivot bearing-side end regions 60, 64 towards the free end. It can be seen that an actuation bead 51 is present at the free end of the manual actuation area 50.
  • a conductor receiving space 54 for receiving the electrical conductor to be clamped is provided between the side wall sections 52, 53.
