Definitions

  • the invention relates to a flat contact spring for plugs of electrical plug-in connectors, which has crimp attachments for connecting electrical conductors and a recess with its edge surfaces that supports a retaining tongue fixed to the spring housing.
  • a sheet metal blank is provided with a first section which has a central strip and longitudinal strips which can be folded up thereon, the longitudinal edge strips of which have cutouts adjoining the peripheral edges which, when the longitudinal edge strips are opened on the central strip, together have an undercut Form a recess and a second section is provided with a central strip and longitudinal edge strips which can be opened thereon, the longitudinal edge strips of which have hook-shaped cuts which, when the longitudinal edge strips are unfolded on the central strips, fix the longitudinal edge strips of the first and second sections together in a form-fitting manner Engage the recess in the longitudinal edge strips of the first section.
  • the doubling of the flat contact spring achieved by the folding processes of the longitudinal edge strips allows an easily cut thin sheet material to be used for the flat contact spring and results in the bending edges strengthening the flat contact spring, in particular transversely to the contact spring plane.
  • fixing the undercuts through the hook-shaped cuts fixes the sections of the two sections lying one above the other.
  • the contact spring can be made with the same thickness over its entire length and width.
  • the first section in the middle strip and the longitudinal edge strips thereof can have indentations on the edge edges on the same side, which, when the longitudinal edge strips are unfolded on the middle strips, form groove-like deposits on both sides of the flat contact spring.
  • the deposits perform leadership functions during the plugging process and also enable the flat contact spring to interact with sockets of different ner width and opening widths, with the possibility that contacting may only be via the
  • the second section in the center strip has a recess in the middle and the longitudinal edge strips of the second section in the regions of the edge edges have recesses with half the width of the recess for the center strip, and that when the longitudinal edge strips are unfolded on the center strip, the outer
  • the same recesses with the recess of the central strip form a recess with the same axis, the edge edges of which can be brought into effect with spring tongues fixed to the spring housing.
  • the central strips and the longitudinal edge strips of the first section are delimited at their free ends in the plane of the section and at the edge edges by inclined surfaces.
  • the inclined surfaces can be formed by grinding or pressing the free ends.
  • the sheet metal blank with the end facing the crimping lugs on a flat strip of greater length, on which any number of further sheet metal blanks are arranged.
  • the flat strip facilitates the handling of the sheet metal blanks, in particular over the duration of the pressing and bending processes or during further processing, e.g. B. galvanic metal orders.
  • the flat contact store and transport in a space-saving manner, whereby by separating the flat contact springs from the flat strips, they are each freely available.
  • the process steps are that the two sections are cut from a flat, thin sheet material with central strips and longitudinal edge strips and crimp connections, the central strips and the longitudinal edge strips of the first section are provided with indentations, and the longitudinal edge strips of both sections onto the central strips the same opened and by engaging the hook-shaped.
  • the longitudinal edge strips are fixed to one another in the cutouts of the second section into the cutouts of the first section.
  • FIG. 2 shows a sheet metal blank for a flat contact spring according to FIG. 1 and
  • FIG. 3 shows a section along the line III-III of FIG. 1
  • the flat contact spring 1 of FIG. 1 can be erected from a sheet metal blank according to FIG. 2.
  • the sheet metal blank 2 has a first section 3 with a central strip 4 and longitudinal edge strips 5 and 6 arranged on both sides thereof.
  • the longitudinal edge strips 5 and 6 are provided with cutouts 7, 7 'adjoining the edge edges of the longitudinal edge strips.
  • the sheet metal blank has a second section 8, which has a central strip 9 and longitudinal edge strips 10 and 11 on both sides with hook-shaped cuts 12 and 13.
  • the sheet metal blank is also included Approaches 14, 15 provided that form crimp approaches after bending.
  • the sheet metal blank 2 is integrally connected via a web 16 to a flat strip 17, in which are formed in transport openings 18 and coding openings 19 for determining the distance from adjacent sheet metal blanks.
  • the edge strips 5 and 6 can be folded up about bending lines 20 on the central strip 4, the cutouts 7, 7 'jointly resulting in a recess with undercuts 21.
  • the hook-shaped cuts 12, 13 engage together in this recess and fix the longitudinal edge strips 5 which are opened onto the central strips 4, 9 , 6, 10, 11 of both sections 3, 8.
  • the hook-shaped sections 12, 13 are supported here on the undercuts 21.
  • a recess 22 arranged in the central strip 9 of the second section 8 and recesses 23, 23 'of half width provided in the longitudinal edge strips 10, 11 form a common recess when the longitudinal edge strips 10, 11 are opened on the central strip 9, the boundary surfaces thereof 24 can be used as support surfaces for housing-fixed retaining tongues (not shown).
  • the free ends of the central strip 4 and the longitudinal edge strips 5, 6 of the first section 3 are provided with bevels 25, 26 which enable the flat contact spring 1 to be easily inserted into the socket body (not shown).
  • the bevels 26 can be achieved by cutouts 28 in the sheet metal blank.
  • FIG. 3 shows that the median strip 4 and the longitudinal edges 5, 6 of the first section 3 have impressions 27, 27 ', which before the folding process of c
  • the indentations 27, 27 ' result in a groove-shaped thin point and allow the flat contact spring 1 to interact with socket bodies of various configurations and opening widths.

Abstract

Afin d'améliorer la stabilité d'un ressort de contact à lame pour fiches mâles de connecteurs électriques qui comprennent des sertissages crimp de raccordement de conducteurs électriques et un évidement qui soutient avec des faces marginales une languette de retenue fixée dans le logement du ressort, le ressort de contact à lame est formé d'une pièce métallique découpée avec une première section (3) composée d'une bande centrale (4) et de bandes marginales longitudinales (5, 6) rabattables sur celle-ci. Les bandes marginales longitudinales (5, 6) comprennent des découpures (7, 7') qui vont jusqu'à leurs bords et qui forment ensemble un évidement contre-dépouillé lorsque les bandes marginales longitudinales (5, 6) sont rabattues sur la bande centrale (4). Une deuxième section (8) de la languette comprend une bande centrale (9) et des bandes marginales longitudinales (10, 11) rabattables sur celle-ci, qui ont des saillies (12, 13) crochues qui pénètrent ensemble par liaison de forme dans l'évidement formé par les bandes marginales longitudinales de la première section (3) lorsque les bandes marginales longitudinales (5, 6) sont rabbatues sur la bande centrale (4), fixant ainsi les bandes marginales longitudinales (5, 6, 10, 11) des première et deuxième sections.
