Definitions

  • the invention relates to an electrical connector part with a housing made of plastic with at least one row of juxtaposed receiving chambers for the contact elements separated by transverse webs and at least one integrally formed on the outer housing wall, which can be brought from an open position into a locking position about an axis pivotable locking arm, the cross section of which is approximately L-shaped and which in the open position releases the cross section of the respective receiving chambers and which narrows the cross section in the locking position and thereby holds the contact element located therein between an end stop and the free end of the locking arm, this free End protrudes through at least one opening recessed in the housing and the locking arm is locked in the locking position with respect to the housing.
  • each receiving chamber is assigned a locking arm, which in its locking position either engages or is held in its locking position by a second housing part pushed onto the housing (EP 0164 211 B1; DE 39 33 959 C2; DE 43 01 602 C1). Since such plug connection parts have only very small dimensions, that is to say are small, these constructions are extremely filigree and the injection molding tools required for their production are extremely complex and complicated and therefore prone to failure.
  • the electrical connector according to DE 35 44 180 C2 should also be mentioned.
  • the wall of its housing there are individual cutouts opening into the receiving chambers of the contact elements. Toothed projections are formed on one leg of the L-shaped locking arm, which protrude through these recesses in the locking position of the locking arm.
  • these tooth-like projections are extremely filigree.
  • the locking arm is practically freely movable in its original open position, so that this locking arm can assume any positions and positions relative to the housing, so that such a connector cannot be manipulated on machines, unless complex mechanisms are developed which are used in the automatic further processing and further processing of such a connector plug hold the locking arm in a clearly definable and repeatable position.
  • the invention is based on this state of the art and aims at designing an electrical connector connection part so that it can be manufactured with comparatively simple and thus robust tools, but above all the connector part is to be designed in such a way that it can be manipulated on production machines is and that its locking is able to withstand the required high mechanical stresses.
  • this is achieved in that the short leg of the locking arm causing the locking of the contact elements and the opening recessed for its reception in the housing extend across the row of receiving chambers, with the locking arm in the open position between an edge of the opening and the free edge of the short leg at least one web serving as a predetermined breaking point is provided and at least one of the boundary edges of the opening running transversely to the receiving chambers intersects the pivoting path of the small leg of the locking arm and the small leg is held in a form-fitting manner in the locking position within the housing, the Axis of the locking arm opposite the locking edge of the free end of the short leg from this axis has a distance which is a small amount smaller than the distance of the boundary edge of the opening adjacent to the axis of this axis and the short legs of the locking arm is integrally formed over its entire length.
  • the electrical connector part has a housing 1 made of an electrically insulating plastic material and has essentially a rectangular, cuboid shape.
  • This connector part is designed as an injection molded part.
  • receiving chambers 3 are recessed by a row of mutually spaced, adjacent cross webs 2, into which contact elements can be inserted.
  • Such contact elements are offered commercially.
  • Openings 5 are left in the upper end face 4, through which the pin-shaped contact elements of a second plug connection part can be inserted, but which are not shown here.
  • a locking arm 6 is integrally formed, which extends essentially over the width D of the housing 1 and its axis 7 below, about which this locking arm 6 can be pivoted, by a film hinge 8 is formed.
  • this locking arm 6 is connected to the front broad side 13 of the housing via two small webs 9. These webs 9 hold the locking arm 6 in a clearly defined position or position relative to the housing 1, which is an important feature for the subsequent manipulation of the connector part in automatic placement machines.
  • the locking arm 6 has an L-shaped cross-section (FIG. 4) with a long leg 10 and a short leg 11, this short leg 11 having a latching edge 12 at its free end facing the film hinge 8.
  • a slot-shaped opening 14 which extends over its width D and lies in the swiveling range of the small leg 11 of the locking arm 6 and in the individual transverse webs 2 delimiting the receiving chambers for the contact elements are correspondingly located Recesses 15, the inside edge 16 of this recess by a dimension T compared to the front broad side 13 of the housing 1 is set back, which corresponds at least to the length of the small leg 11 of the locking arm 6.
  • the lower boundary edge 17 of the slot-like opening 14 intersects the pivoting path of the small leg 11 or its latching edge 12, as is indicated by the curved line 18 in FIG. 5, which denotes the pivoting path of the latching edge 12.
  • the two legs 10 and 11 of the locking arm 6 together form an acute angle.
  • the short leg 11 of the locking arm 6 is integrally formed over its entire length.
  • the recesses 15 described above are recessed in the crosspieces 2 of the receiving chambers 3. If these recesses were not present on the crosspieces 2, incisions are provided on the short leg 11 of the locking arm 6 in or parallel to the pivoting plane of this locking arm, into which the crosspieces 2 dividing the receiving chambers 3 project in the locking position of the locking arm.
  • the above-mentioned webs 9 are provided at the upper edge of the opening 14. It is also possible to arrange these webs at the lower edge of this opening 14. Instead of two webs, only one web can be provided or more than two webs.
  • FIG. 6 now shows a vertical cross section like FIG. 5, but here a commercially available contact element 19 with a lead wire 20 connected to it is already inserted into the receiving chamber 3.
  • This contact element 19 has resilient spreading wings 21, with which it holds itself in the receiving chamber 3.
  • the locking arm is pressed against the housing 1 (arrow 22), its short leg 11 snapping in and snapping in the manner illustrated here and thereby positively engaging behind the part of the contact element 19 serving to connect the lead wire 20 and so forms a second fuse for the contact element.
  • the latching edge 12 of the leg 11 passes over the lower boundary edge 17, this leg 1 being raised somewhat and then, as soon as the latching edge 12 has passed over the lower boundary edge 17, snaps in and engages.
  • FIGS. 1 to 6 has a row of receiving chambers 3.
  • FIG. 7 shows a housing which has two parallel rows of such receiving chambers 3. Slot-like openings 14 and locking arms 6 are formed and formed on both broad sides 13 of this housing 1, so that the housing 1 has a substantially symmetrical cross section.
  • the contact element 19 is designed as a receiving contact element.
  • the measure according to the invention which relates to the housing, can also be used where pin-shaped contact elements are arranged in the receiving chambers of the housing and are received by the contact elements 19 shown during the production of the contact connection.
