Definitions

  • the invention relates to a method for producing an at least partially elastically compressible clamping area which forms a section of a pin-shaped element and which is provided for the non-positive fixing of the element in a bore, the clamping area being divided by dividing the element into at least two legs their two ends are connected to each other, and an increase in the distance between these two legs is obtained.
  • Such a method is known from GB-PS 1 149 332.
  • the element is first pressed flat in the 'clamping area.
  • the flattened section is then provided with a slot, so that there are two legs connected at their two ends in the flattened section of the element.
  • the legs are rounded on the outside in order to adapt the outer contour of the legs to the curvature of the bore provided for receiving the element.
  • This adaptation of the outer contour of a clamping area to the rounding of a hole into which the element is inserted is necessary so that, for. B. a surface metallization of the hole can not be damaged by inserting the element.
  • Such elements form e.g. B. with a section to be inserted into the holes of a circuit board contact pins, contact blades or contact springs, which are combined in multi-pin, knife or contact spring strips.
  • the object of the present invention is therefore to develop a method of the type mentioned at the outset such that the clamping region can be produced in as little as possible in one operation while maintaining its full functionality, in particular by creating an outer contour adapted to the bore rounding.
  • this object is achieved in that the division of the element into two legs by means of two wedges which can be moved in opposite directions with wedge edges aligned parallel to the longitudinal axis of the element and having a wedge angle of approximately 30 ° to 60 ° is carried out in such a way that either the wedges are pressed into the element at the same time, with a slight offset of the wedge-shaped cutting edges, or that the wedges are pressed into the element one after the other with wedge-shaped edges aligned with one another, with appropriate support of the element on the opposite side, and that when the wedges are pressed into the Element evasive legs are intercepted transversely to the direction of movement of the wedges through the bore rounded abutment.
  • the abutments provided transversely to the direction of movement of the wedges or chisels are designed to be resilient, so that the profile of the branches is not changed when the flat wire piece is divided. A profile change of the branches is made only in a separate second pressing process.
  • FIGS. 1 to 4 it can be seen from FIGS. 1 to 4 that the incorporation of a clamping area into a pin-shaped element 1 which has a square cross section (the cross section of the element can of course also be round, oval, rectangular or polygonal) with the aid of two wedges 2, 3 is made, the wedge edges 4 have an angle of 60 °.
  • the wedge edges 4 are directed parallel to one another and to the axis 5 of the element.
  • the wedges 2, 3 can either as shown in Figures 1 and 2, simultaneously or, as can be seen from Figures 3 and 4, in succession which are moved into element 1. If the wedges 2, 3 are to be simultaneously moved into the element with their wedge edges 4 moving in opposite directions, it is necessary, as can be seen from FIGS. 1 and 2, the planes of motion 6 of the wedges 2, 3 against one through the axis 5 of the element 1 extending plane of symmetry 7 of the element 1 so that, as can be seen in particular from FIG. 2, the two wedges 2, 3 in their end position reached after dividing the element 1 into two legs 8 with their wedge edges 4 overlap each other.
  • the legs 8 are increasingly moved apart.
  • this movement is limited by two abutments 9, which are designed on their sides facing the element 1 as half-shells 10, which are adapted to the rounding of the bore into which the element 1 is to be inserted.
  • the legs 8 are pressed with their outer side 11 facing away from the axis 5 of the element 1 by the wedges 2, 3 against the curves 10 of the abutment 9 and thereby adapted to these curves.
  • the element therefore has a cross section in the clamping area, cf. 6 and 7, in which each of the two legs 8 has an outer face 11 adapted to the rounding of the bore and a wedge-shaped inner face 12 facing the opposite leg, so that the space 13 separating the legs 8 is formed like a butterfly.
  • the wedges 2, 3 are successively moved into the element 1, cf. 3 and 4, the wedges 2, 3 with their planes of movement, which coincide with the planes of symmetry of the wedge cutting edges 4, can be aligned with a plane of symmetry 7 of the element 1 running through the axis 5 of the element.
  • the shaping of the outside 11 of the legs 8 is also carried out when the wedges 2, 3 are successively pressed into the element 1 in the same way as in the method according to FIGS. 1 and 2 with the aid of two abutments 9.
  • a plurality of clamping areas 15 can also be incorporated into an element 1 in the direction in which the element extends, the clamping action of the successive clamping areas 15 advantageously being offset from one another by 90 °.
  • Fig. 8 From Fig. 8 it can be seen that the wedges 2, 3 run with their wedge edges 4 to the connection points 16 of the legs 8 each beveled, so that the legs 8 from a central portion 17 in which the legs 8 parallel to each other run at a certain distance from one another and thus form the actual clamping area, continuously approach each other again, that is to say run together.
  • the element 11 In this area 1, the element 11 has a contour that is optimally matched to the bore due to the outside 11 of the legs 8 adapted to the rounding of the bore.
