Definitions

  • the invention relates to an electrical connector, consisting of a trough-shaped receiving part and a plug part which can be plugged into it, with the features of the preamble of patent claim 1.
  • coding in the plug housing to protect against incorrect insertion.
  • a coding rib is formed on one part, for example the plug part, while a complementary coding groove is provided in the other part, that is to say, for example, in the receiving part.
  • the plug part can then only be inserted into the receiving part with a certain orientation, provided that the latter has a corresponding coding groove.
  • the object of the present invention is therefore to design a plug connector of the type mentioned at the outset in such a way that inadvertently oblique insertion and thus damage to the plug pins is reliably excluded.
  • the width of the connector part with the respective opposite safety ribs is greater than the greatest clear width of the plug-in channel between the cutouts in a connector of the type mentioned.
  • the design according to the invention is of particular importance in the event that the plug-in channel of the receiving part has an enlarged internal width due to cutouts in the longitudinal side walls approximately in the central region.
  • This is provided, for example, in the connector according to DE-GM 87 14 016 for the purpose of arranging organs for locking the plug connection in an enlarged gap between the plug part and the receiving part. If in such a case the locking members are attached to the plug part and the plug-in channel of the receiving part has relatively large recesses in the central area, the risk is very great that an obliquely inserted plug part can be inserted relatively far in this central area of the plug-in channel and even there the height of the reset pins is reached.
  • the safety ribs can be set back from the front end face of the plug part by a distance which is in any case less than the safety distance of the plug pins.
  • the safety ribs of a side surface are expediently each at a different distance from the end edges of the side surfaces. This way, a kind of additional coding against incorrect polarity is achieved via the safety ribs, even when plugged in straight.
  • the security ribs can at least partially be formed as projections on an existing coding rib.
  • the plug part 1 shown in FIGS. 1 to 3 has a housing 2 which has an essentially rectangular cross section, at least in the lower part 2a. This lower part is delimited on the outer circumference by the longitudinal sides 3 and 4 and by the transverse sides 5 and 6.
  • the front end in the plugging direction is delimited by an end face 7 which has a plurality of plug openings 8 (in FIG. 2 are only some of them indicated).
  • the housing has a cavity 9, into which (in FIG. 1 from the left) socket strips can be inserted.
  • These socket strips, not shown, have a corresponding socket behind each plug opening 8.
  • the insertion opening for the socket strips is closed in the present example by a plug-on closure plate 10.
  • a cable feed channel 11 is also formed on the top of the plug part 1.
  • the plug part has a coding rib 12 known per se at one end.
  • the receiving part 20 shown in FIGS. 4 and 5 has a housing base 21 which has a multiplicity of plug pins 22, only a few of which are indicated in FIG. 5.
  • the height of the connector pins 22 is indicated in FIG. 4 by the dash-dotted line 22 '.
  • the connector pins are enclosed by a circumferential collar of the receiving part, which is formed from two longitudinal side walls 23 and 24 and two transverse side walls 25 and 26. These side walls thus form a plug-in channel 27 into which the plug part 1 can be inserted.
  • the plug part is guided with its transverse side surfaces 5 and 6 on the transverse side walls 25 and 26 and with its longitudinal side surfaces 3 and 4 on guide sections 28, 29, 30 and 31 of the receiving part.
  • coding grooves 32 are provided in the receiving part, so that even when inserted vertically and with correct alignment, only the associated plug part can be inserted into the receiving part.
  • the coding rib in the example shown is only on the right side in the picture, it does not prevent the plug part from being inserted incorrectly in the inclined position, that is to say with the end edge on the left in the picture.
  • the connector part can of course not be fully inserted, the connector pins 22 can still be damaged. This applies even more to the example shown, since recesses 33 and 34 are provided in the receiving part in the longitudinal side walls 23 and 24 between the guide sections 28 and 30 or 29 and 31, respectively, which create space for a locking device (not shown) between the receiving part and the plug part . In this case, the connector part could even be inserted obliquely with the coding ribs 12 ahead.
  • additional safety ribs 35, 36, 37 and 38 are formed on both sides in the end regions of the longitudinal side surfaces 3 and 4 of the plug part, through which the plug part is given a width at the ends, which is larger in each case than the greatest clear width of the plug-in channel 27 between the cutouts 33 and 34.
  • the safety ribs 35, 36, 37 and 38 mentioned are correspondingly assigned corresponding safety grooves 45, 46, 47 and 48 in the receiving part.
  • these safety ribs 35 and 36 at one end of the plug part and the safety ribs 37 and 38 at the other end of the plug part each have a different small distance from the respective end edge or the transverse side faces 5 and 6, respectively thus also the guarantee that the connector part cannot be inserted rotated by 180 ° in the vertical direction.
  • the additional safety grooves 45, 46, 47 and 48 reduce the wall thickness of the receiving part in their area, it is desirable not to make these grooves too deep. For this reason, in the present example, the safety ribs 35 to 38 are not led to the end face 7, but are set back by a certain distance, so that the safety grooves 45 to 48 do not need to be very deep either. However, this distance between the recessed safety ribs must not be greater than the distance between the upper ends of the plug pins 22, as indicated by the dash-dotted line 22 'in FIG. 4, from the upper edge 39 of the side walls 23 and 24. This means that the connector part can be up to to a certain depth also inserted obliquely, however, the connector pins 22 are not at risk.

Abstract

Ce connecteur enfichable, composé d'une partie femelle en cuvette et d'une partie mâle enfichable dans la partie femelle et s'adaptant à celle-ci, possède dans chacune de ses zones terminales des nervures de sûreté qui donnent ensemble à la partie mâle une largeur supérieure au plus grand diamètre intérieur de la partie femelle. On évite ainsi un enfichage en biais et donc un endommagement des broches de connexion disposées dans la partie femelle.
