Definitions

  • the invention relates to a flat contact spring for plugs of electrical connectors with socket contacts having socket bodies and method for the production thereof.
  • the known flat contact springs for plugs are formed by flat sheet metal blanks, crimping attachments being connected to a contact spring tongue which can be inserted into the socket contact of a socket body for the fixing of the electrical connecting lines and their insulation.
  • the contact spring tongue is formed as a solid body from a relatively thick sheet material. Apart from the difficult cutting processes in the case of thick sheet metal sections, in the case of such flat contact springs, an adaptation of the thickness of the contact spring tongue to the clear width of the openings of socket contacts can only be achieved by using more or less thick sheet metal materials.
  • the contact spring tongues formed in this way have only a slight bending moment and are therefore in many cases inadvertently bendable, as a result of which the plug-in processes of these flat contact springs are adversely affected.
  • this object is achieved by a flat contact spring according to claim 1.
  • the median strip is provided with two indentations extending parallel to one another in the longitudinal direction and the lateral strips are each provided with the same indentation, such that when the lateral strips are folded in, the indentations of the medial strip and lateral strips lie one above the other and form all-round closed chambers.
  • the indentations enable the contact spring tongue to be adapted to any thickness by corresponding depths and, due to the limiting surfaces of the indentations extending transversely to the plane of the contact spring tongues, increase the bending moment, thereby avoiding bending of the contact spring tongue and consequent incorrect plugging.
  • the central strip and the two side strips have bevels which extend obliquely to one another on the outside toward the free ends.
  • the bevels can be made by grinding or chip-free deformation, e.g. B. pressing, can be achieved, whereby between the median strips and folded side strips form cutting with subsequent inclined surfaces, which facilitate the insertion of the contact tongue into socket contacts.
  • the side strips on the median strip can be folded down freely. According to a preferred embodiment, however, the free ends of median strips and side strips are together, for. B. firmly connected by welding, soldering or gluing.
  • the fixed connection is advantageously carried out in the area of the common parting plane of the two side strips. The fixing of the strip parts to one another in this way prevents undesired bending of the same.
  • edge strip on the sheet metal blank at the end facing the crimp attachments, on which further sheet metal cuts are arranged.
  • the edge strip facilitates the handling of the sheet metal blanks, in particular over the duration of the embossing and bending processes or during further processing, e.g. B. galvanic metal orders.
  • the flat contact springs are freely available by separating them from the edge strip.
  • the method steps according to claim 5 are provided for the manufacture of the flat contact springs.
  • the central strip 2 and one on each side of this Side stripes 3 has half the width.
  • the two side strips 3 and the central strip 2 are formed together with crimp attachments 5 and 6 by a flat sheet metal blank 7.
  • the sheet metal blank 7 is cut with further sheet metal blanks 7 on an edge strip 8.
  • the median strip 2 is provided with two parallel indentations 9, while the two side strips 3 each have an identical indentation 9.
  • the indentations 9 can have predetermined depths for different thicknesses of the contact spring tongue 10.
  • the two side strips 3 can be folded onto the median strip 2.
  • the indentations 9 of median strips 2 and side strips 3 lie one above the other and form chambers 11.
  • the lateral boundaries of the chambers 11 and the bending edges 12 lead to a strengthening of the contact spring tongue 10 and an increase in the bending moment thereof.
  • the central strips 2 and the side strips 3 are provided with bevels 13 at their plug ends, which together form a cutting edge 14 with adjoining inclined surfaces 15 when the side strips 3 are folded onto the central strip 2.
  • the cutting edge 14 and the inclined surfaces 13 facilitate the insertion processes of the flat contact spring in socket contacts (not shown).
  • the inclined surfaces lead to automatic centering of the contact spring tongue 10 during insertion processes.
  • the crimp extensions 5 are suitable for fixing electrical conductors 16 by bending up and down (FIG. 8), while the crimp extensions 6 serve to fix the insulation 17 of the electrical conductors 16.
  • the contact spring tongue 10 has a recess 18 which passes through both the median strip 2 and the side strips 3.
  • the recess 18 results from appropriately prepared openings in the central and side strips 2, 3. It is used (FIGS. 7 and 8) to support a plug housing-fixed tongue 20 when inserting the flat contact spring 1 into a plug housing 19, which in turn has an axial Fixation of the flat contact spring 1 in the connector housing 19 causes.
  • the tongue 20 is prevented from unintentional bending back and the flat contact spring 1 is held immovably in the connector housing 19 by a slide 23 inserted into the connector housing 19 and fixed by means of a tongue 22 engaging in a recess 21.
