Definitions

  • the present invention relates to a cable receiving device, a connector system, a method of connecting and the use of a cable receiving device.
  • a ribbon cable with multiple conductors is used for bus lines.
  • a plurality of conductors are embedded in a lsolierstoff film, wherein the individual conductors have a small cross-section and a small distance from each other.
  • the electrical conductors of the ribbon cable are exposed at a cable end of the ribbon cable and this Jardinend Scheme is inserted into a suitable cable receiving device, so that the cable end of the ribbon cable is clamped by resilient contact elements. By this clamping takes place an electrical or mechanical contacting of the ribbon cable or its electrical conductor.
  • the cable receiving device is versatile and very easy to produce.
  • the term “substantially” may describe a slight deviation from a target value, in particular a deviation within the manufacturing accuracy and / or within the necessary accuracy, so that an effect is maintained as it is present at the target value.
  • the term “substantially” may therefore include a deviation of less than about 30%, less than about 20%, less than about 10%, less than about 5%, less than about 2%, preferably less than about 1% of a target value or set position, etc. include.
  • the term “substantially” includes the term “identical,” i. without deviation from a desired value, a desired position, etc.
  • interior in particular describes a volume region bounded, for example, by the housing of the cable receiving device.
  • the term “interior” describes the internal volume of the cable receiving device. In this case, it is not necessary that the cable receiving device is closed.
  • the cable receiving device may have an insertion opening section or an opening, for example to introduce a flat cable end or a ribbon cable. Nevertheless, the term “interior” describes the interior volume as if the opening were closed. In other words, the term “interior” describes the internal volume of an ideally completely closed cable receiving device.
  • the term “interior” analogously includes e.g. also "essentially inside” or "at least partially inside”.
  • the "insertion direction" in the sense of the present invention is for example a direction in which one or more electrical conductors in the cable receiving device be introduced or are insertable.
  • the insertion direction may be parallel to a longitudinal axis of one or all electrical conductors.
  • the insertion direction may also be perpendicular to the surface which is spanned by the edge of the Ein Industriesö Maschinensabitess or the opening.
  • the insertion direction E can be a direction determined or determinable by the shape of the cable receiving device and / or the end region of the cable.
  • the insertion direction E can be or be predetermined and the curvature along this insertion direction E be determined or be.
  • a "radius of curvature" R of a plane curve at an arbitrary point P of this plane curve is understood to mean the radius R of a clearly defined circle with center M, which coincides with the curve at point P in the second order.
  • the radius of curvature R of a curved surface along a direction for example, the insertion direction E, can be defined.
  • the curved surface is cut by a sectional area which is spanned by the (insertion) direction E and the normal vector of the curved surface at the point P and passes through the point P.
  • the section line is thus a plane curve to which the above definition of the radius of curvature R can be applied.
  • the solder from the center M to the point P is substantially perpendicular to the insertion direction E.
  • the cut surface may be, for example, a symmetry surface or plane.
  • the cut surface may also be a surface that is parallel to the insertion direction E and when cut with a surface of the contact element forms a substantially continuous curve. On this curve, the above and the following explanations can be applied to the curvature.
  • the "curvature" K of a curve or surface is defined by the reciprocal 1 / R of the radius of curvature R. Since the radius of curvature is positive, the curvature is basically positive. In order to distinguish opposing curvatures, a sign of the curvature is defined, ie there exists a positive curvature and a negative curvature.
  • a curved curve divides a plane in which the curve lies, at least locally in two half-planes.
  • a curved surface divides the space in which the curved surface lies, at least locally into two half-spaces.
  • the cable receiving device described above accordingly comprises an end region, a transition region and an actuating region, wherein these regions are in particular made of a curved sheet metal piece.
  • the end region is connected by the transition region with the actuation region, so that the regions are connected to one another continuously, ie essentially without jumps and / or punched locations.

In other words, the transition from the curvature K B to the curvature K E takes place essentially continuously and in particular not abruptly, so that essentially every curvature value K E ⁇ K Ü ⁇ K B is reached in the transition region during the steady transition.
  • the definition of the positive and negative curvature regions may alternatively be made by the tangent to the curved curve at the inflection point of the transition region. This tangent also separates the regions of the curve with opposing, i. with positive and negative curvatures. Points of the (intersection) curve which lie in the half-plane or half-space in which the center of a circle of curvature of the actuation region is positive are curvatures at points of the (intersection) curve which are in the other half-plane and the other, respectively Halfspace are negative (or vice versa).
  • curvature particularly describes curvature of a curve, a change of direction per unit length.
  • the curvature thus describes the course of a curve.
  • the curvature of a straight line is zero everywhere because its direction does not change.
  • a circle with the radius R has the same curvature everywhere, namely 1 / R, since its direction changes equally everywhere.
  • the curvature changes from curve point to curve point.
  • the curvature of a curve at a point P thus indicates how much the curve in the immediate vicinity of the point P deviates from a straight line.

  • the radius of curvature at point P is shown as a dotted line.
  • the radius of curvature at point P is R B.
  • the curvature of the Actuation area 13 at the other points of the operation area 13 is different from the curvature at the point P.
  • the curvature it is also preferably possible for the curvature to be constant throughout the actuation area 13.
  • the dotted line is identical to the line representing the contact surface 19. In the transition region 12, however, no constant curvature is possible because in the transition region 12, the curvature passes from the actuating region 13 to the end region 11.
