Definitions

  • the invention relates to a contact female connector with an elongated insulating housing, which extends between a front and a rear, parallel to one another and arranged in a rectangular grid with essentially rectangular cross-section, into each of which a contact pin or knife of the Front of the bar is insertable and consists of a front upper and a rear lower part, the upper and lower part can be locked together.
  • Such a contact female connector is known from DE-GM 7 112 653. With such a strip, the two-part design of the housing enables the contact springs to be locked in the chambers and thus to make the contact springs interchangeable.
  • Such strips can be connected, for example, to a pin strip or knife strip, the ends of the contact pins or contact blades protruding from the pin strip or knife strip penetrating into the chambers of the contact spring strip and contacting the contact springs located in these chambers.
  • Such a contact female connector can also be plugged onto pins of a wrap pin array. On the back of the bar, the contact springs may in turn in contact blade, Wra p pins or solder tails pass with which the contact springs of the contact spring strip to be connected to further lines.
  • the contact springs of such a contact spring strip have insulation displacement contacts which penetrate the insulation of the ribbon cable and at the same time accommodate a single conductor of the ribbon cable in a contact slot.
  • the ribbon cable is inserted into a slot formed by the lower part of the strip, as is known, for example, from DE-OS 27 36 244, and only after the ribbon cable has been inserted into this slot is that with. the upper part of the strip equipped with the contact springs is connected to the lower part, the insulation displacement contacts being moved automatically against the ribbon cable and contacting their associated individual conductors when the upper part and lower part of the strip are locked.
  • the object of the present invention is therefore to design a contact female connector of the type mentioned in such a way that the upper and lower parts of the strip can be aligned precisely with one another before the upper and lower parts are locked and, on the other hand, the strip can be plugged unhindered onto a portion of a wrap pin field can be.
  • this object is achieved in that the ends of the bar immediately adjacent Chambers are essentially formed by the lower part of the bar and the remaining chambers at least in a region near the front of the bar from the upper part of the bar.
  • a contact spring strip is created which, at the ends of the strip with the lower part of the strip, one-piece, relatively stable posts for aligning the upper part with the lower part, even before the upper part is locked with the lower part, and in which the Posts do not hinder the attachment of the bar to pins of a wrap pin field, since the bar has so-called blind chambers in the area of the posts, ie Chambers which are identical in their cross-sectional dimensions and in their arrangement to the chambers of the bar which can be fitted with contact springs and into which wrap pins arranged in grid dimensions can consequently penetrate unhindered.
  • the chambers immediately adjacent to the ends of the strip have a bottom formed by the lower housing part at right angles to the direction of insertion of a contact pin or knife.
  • Appropriate arrangement of the bases can advantageously be used to create stops which limit the insertion depth of a wrap pin, so that lines connected to the wrap pins are not impaired when the contact female connector is plugged onto pins of a wrap pin array.
  • the figure shows an oblique view and a greatly enlarged upper and lower part of the contact spring strip before joining the two parts.
  • the strip-shaped insulating material housing of the contact spring strip is composed of an upper part 1 and a lower part 2, the lower part having posts 3 at both ends, between which the upper part 1 must be inserted before it is connected to the lower part can be locked.
  • the upper part 1 is U-shaped in cross-section, the U-legs being formed by longitudinal walls 4 protruding from the upper part 1 to the lower part 2.
  • Recesses 5 are provided in the longitudinal walls 4 of the upper part 1, into which latches 6 provided on the lower part 2 engage when the upper part 1 and lower part 2 are joined and thereby connect the upper part 1 and lower part 2.
  • the upper part 1 has chambers 7 arranged in a certain rectangular grid, which pass through the upper part parallel to one another between a front side 8 and a rear side facing the lower part. These chambers are intended for receiving contact springs, not shown, which can be inserted into the chambers 7 from the rear of the upper part and are provisionally fixed in the upper part 1.
  • the contact springs protrude from the rear of the upper part and penetrate into a ribbon cable, which is inserted into the receiving slot 9 of the lower part 2, before the upper part 1 locks into the lower part 2
  • the upper part must already be locked the lower part must be aligned precisely with the lower part in order to prevent a single conductor of the ribbon cable from being missed by its assigned insulation displacement contact.
  • the grid arrangement of the chambers 7 is also continued in the area of the posts 3 with the aid of so-called blind chambers 10, the walls of these blind chambers 10 in one area , in which the walls of the chambers 7 for receiving the contact springs are formed entirely by the upper part 1 of the contact spring strip, on three sides, the substantially rectangular cross-sectional chambers 10 from the lower part and on the fourth side, - this is the inner chamber wall of the blind chambers 10, which each run away from the end face 11 of the contact spring strip parallel to this, - are formed by the end faces 12 of the upper part.
  • the blind chambers 10 are provided with trays 13 extending at right angles to the direction of insertion of a contact pin or contact knife into the chambers 7, the trays 13 being arranged in the blind chambers 10 at such a height that they are effective as stops for wrap pins inserted into the blind chambers 10 and thus also limit the insertion depth of the wrap pins in the chambers 7.
