Definitions

  • the invention relates to an electrical plug contact made of a stamped sheet metal part with a claw part and a contact part and a preferably box-shaped spring arm base forming a cavity between the claw and the contact part.
  • Such electrical plug contacts are known in which a correspondingly shaped spring arm base of an outer spring from a sheet metal stamping is usually mounted on the outside of the spring arm base, the spring arms of which are supported on the spring arms of the plug contact and whose spring force is to be increased; because the material from which the plug contacts are made is mostly flexible and mintable for electrical and shaping reasons, while the material from which the spring is made of spring steel sheet.
  • the spring arm base of the outer spring usually has detent spring tongues which are bent outwards and are intended to lock the plug contact in a housing chamber of a plug housing.
  • Such locking spring tongues of the spring are preferred because the spring is made of thin, but - as described above - stronger material, so that the locking spring tongues are more elastic and rigid than locking spring tongues formed from the material of the plug contact.
  • the object of the invention is to provide a plug-in contact of the type described at the outset with material-dependent, stronger locking spring tongues without the outer dimensions of the plug-in contact becoming thicker.
  • the electrical plug contact 1 made of a stamped sheet metal part has a conventional claw part 2 and a contact part 4 designed as a Flackstekker 3. Parts 2 and 4 can also be shaped differently than shown.
  • a spring arm base 5 is arranged between the parts 2 and 4, a transition region 6 being provided between the spring arm base 5 and the claw part 2.
  • the spring arm base 5 forms a cavity.
  • the spring arm base 5 is approximately cuboid or box-shaped or rectangular in cross-section with a bottom wall 7 and two side walls 8 and 9, the side walls forming a rear edge 8a or 9a and a front edge 8b or 9b.
  • the top wall is left out by leaving only four square tabs 10a, 10b and 11a, 11b, which are arranged in the area of the rear edges 8a, 9a and in the area of the front edges 8b, 9b, so that a free upper edge is located between the bearing tabs 10a and 10b 8c and a free upper edge 9c appear between the bearing tabs 11a and 11b.
  • the upper edges 8c, 9c are set somewhat lower than the height "H" of the box interior of the spring arm base 5 so that the tabs 10s, 10b, 11a, 11b can be bent more easily (see FIGS. 1 and 4).
  • a square punch 12 is made in the middle.
  • a locking spring tongue base part 13 which is box-shaped in cross-section and made of a spring sheet metal stamping part, is seated in a form-fitting manner and almost without play.
  • the base part 13 has a bottom wall 14, two side walls 15, 16 and a top wall 17.
  • a U-shaped relief 18 is provided in the area of the punched-out section 12, from which a locking spring tongue 19 pointing in the direction of the claw part 2, which is narrower than the punched-out section 12 results, which is bent outward in an arc-shaped manner through the cutout 12 and the first latching spring tongue of the plug contact 1 forms. It can be provided - as can be seen in particular from FIG. 4 - to press the connecting web 14a of the bottom wall 14 for the catch spring tongue 19 into the punched-out portion 12 in a bead-like manner so that the deflection of the catch spring tongue 19 can be made less.
  • the bridge web 14b of the bottom wall 14 opposite the connection web 14a or the latching edge 19a of the latch spring tongue 19 can be pushed through, so that the front edge of the connection web 14a abuts against the front edge of the cutout 12 and the rear edge of the bridge web 14b against the rear edge of the punched-out 12 and thereby hinder a displacement of the base part 13 in the longitudinal direction of the plug contact.
  • the longitudinal slot 20 of the base part 13 is arranged in a side wall 15 or 16, so that it is covered by a side wall 8 or 9 of the spring arm base 5.
  • the dimensions of the tabs 10b and 11b corresponding rectangular recesses 21a and 21b are introduced at a corresponding point in the ceiling wall 17 and the side walls 16 and 15, so that the tabs are form-fitting and as free as possible the edges reach behind the recesses.
  • the same recesses 22a and 22b are provided for the tabs 10a and 11a on the rear claw part side of the top wall 17 and the side walls 16, 15.
  • a second, outwardly bent locking spring tongue 24 is arranged in the ceiling wall 17 by means of two V-shaped cut-outs 23 pointing in the direction of the claw part 2.
  • the dimensions of the recesses 21a and 21b and 22a and 22b are designed in combination with the height "h" of the base part 13 so that the surface of the top wall 17 is flush with the surface of the top wall of the spring arm base 5 formed by the tabs (see FIG. 1, 4 and 5).
  • a base part 13 made of a spring sheet metal stamping part in the interior of the spring arm base of the plug contact 1 makes it possible to provide detent spring tongues which are formed by the base part.
  • the dimensions of the spring arm base of the plug contact are not affected.
  • the spring arm base of the plug contact is rather supported in terms of space by the base part, so that the spring arm base also withstands increased loads.
  • the square cutout 12 is smaller than in the embodiment according to FIGS. 1 to 5.
  • the connecting web 14a and the bridge web (14b) lie flat on the opposite, correspondingly formed, the Punching 12 surrounding edges 7a, 7b of the bottom wall 7 (Fig. 8).
  • the tabs 10a, 11a have substantially rectangular recesses 22a, 22b in the top wall 17 and the side walls 16, 15, depending on their dimensions.
  • the second detent spring tongue 24, like the detent spring tongue 19, is formed by a U-shaped relief 24a in the top wall 17.
  • the plug-in contact is used instead of the through for the displacement-safe mounting of the latch spring base part 13 setting of the connecting web 14a and the bridge web 14b in the region of the rear edge 14c and the front edge 14d of the bottom wall 14, each provided a pressed-in locking edge 7c, 7d produced by a cut running parallel to the edges 14c and 14d, made in the bottom wall 7 of the spring arm base 5, each engages behind an edge 14c and 14d.
