Definitions

  • the invention is based on a multi-pole plug device according to the preamble of the main claim.
  • additional contact springs are arranged in the receptacle having the plug, which are connected at one end to a circuit arrangement of a control unit and rest with their spring end on an associated plug of the receptacle when the plug connector containing the receptacles from the receptacle is withdrawn.
  • the plug connector has a contact carrier which receives the contact parts struck at the ends of the cable harness and which has projections on its side facing the plugs on which certain contact springs of the receiving part slide when the plug connector is in the inserted state.
  • the projections are of different lengths, the connections between contact springs and plugs are released depending on how far the plug connector is plugged into the receiving part. Accordingly, when the connector is removed from the receiving part and thus from the plugs, the plugs are successively connected to independent circuits via the contact springs.
  • Units connected to the wiring harness cannot, however, be secured against undesired and / or damaging actuation with the known short-circuit connection.
  • a plug-in device in which the plug of the plug connector is short-circuited via an intermediate plug when the plug connector is removed from the plugs in the receiving part.
  • the invention has for its object to provide a multi-pin connector, in which the connector connected to the cable harness is to be secured in the withdrawn state against false triggering of units connected to the cable harness.
  • the contact parts connected to the wiring harness are short-circuited when the connector is removed.
  • the gas generators which inflate the airbag or tighten the belt are connected to the electronic release device via the ignition circuit. If the disconnected connector comes into contact with a current-carrying device, for example with a test device, or if assigned pairs of contact parts come into contact due to electrostatic charging when touched by the fitter, the airbag or belt tensioner can no longer be triggered incorrectly because they are connected to the gas generators via the wiring harness connected contact parts are short-circuited by means of the short-circuit bridge.
  • Another advantage is that the pivoting closing and pulling movement of the connector requires a low insertion force or pulling force for the successive closing and opening of the individual contact pairs.
  • the short-circuit bridge can be particularly easily attached to the edge of the connector housing designed as a grip shell.
  • the short-circuit bridge is completely covered or fastened to the contact carrier from the handle shell to the outside, and is thus even better protected against shaking influences during rough operation in motor vehicles and against improper handling leading to damage.
  • the contact tongues of the short-circuit bridge have a longer permissible spring travel, so that the receptacle edge surrounding the plug in the receptacle part can be pushed between the spring tongues and the contact carrier in such a way that the spring tongues are lifted safely and far enough from the contact parts with all permissible tolerance combinations.
  • FIG. 1 shows a first exemplary embodiment of a connector of a multi-pole connector with a short-circuit bridge arranged on the handle, partially in longitudinal section
  • FIG. 2 shows the connector in cross section along the line II-II in FIG. 1
  • FIG. 3 shows a partial section through the released multi-connector with a short-circuited connector Contact part, on a larger scale
  • Figure 4 shows a partial section through the connector in the inserted state with the short-circuit bridge released, also on a larger scale
  • Figure 5 shows a second embodiment of the connector with the short-circuit bridge arranged on the contact carrier, partly in longitudinal section
  • Figure 6 shows the connector in cross section along the Line VI-VI in FIG.
  • FIG. 7 shows a partial section through the released plug device with a short-circuit bridge detachably attached to the contact carrier, on a larger scale
  • FIG. 8 shows a view of the contact carrier in the direction of arrow VIII in FIG. 5
  • FIG. 9 shows a partial section through a modification of the plug connector of the multi-pole plug device according to FIGS. 5 to 8 with a released short-circuit bridge, which is permanently attached to the contact carrier, again on a larger scale.
  • a multi-pole plug device has a plug connector 1 which is connected to a cable harness in a manner known per se and not shown in detail.
  • the plug connector 1 has a contact carrier 2 with contact chambers 3 formed in rows, in which the contact parts 4 which are attached to the ends of the conductors forming the wiring harness and are designed as contact sleeves are inserted.
  • the contact carrier 2 is in a housing designed as a grip shell 5 housed.
  • Contact carrier 2 and handle 5 are made of insulating plastic.
  • the handle 5 is provided on a narrow side with a hook 6, with which the handle 5 and thus the connector 1 in a known and not shown manner on a receiving part 7, in which the contact parts 4 corresponding connectors 8 are arranged, hung and for closing or releasing the multi-pole plug device relative to the receiving part 7 is pivotable.
  • a short-circuit bridge 9 is suspended on the two long sides of the grip shell 5.
  • the short-circuit bridge 9 is provided with spring tongues 10 which, when the connector 1 is removed, protrude through assigned openings 11 in the outer wall 12 of the outer rows of contact chambers and rest on the contact parts 4 used there.
  • their back 13 is U-shaped. Lugs 15 are reeved on its short leg 14 and bent inwards.
  • the grip shell 5 is accordingly provided with notches 16.
  • the U-shaped back 13 of the essentially comb-shaped short-circuit bridge 9 is pushed onto the edge of the grip 5 and is detachably held on the grip 5 by the detents 15 which are engaged in the notches 16.
  • the receiving part 7 has a receiving edge 17 surrounding the area of the connector 8, which projects beyond the ends of the connector 8. On the outside, the receiving edge 17 is provided with a bevel 18 in the end region.
  • the receiving edge 17 slides onto the contact carrier 2 and thus onto the outer walls 12 of the outer rows of contact chambers.
  • the receiving edge 17 lifts the spring tongues 10 of the shorting bridges 9 from the contact parts 4 with the bevel 18.
  • the ent speaking contact parts 4 are no longer short-circuited, but rather, for example, the ignition circuit is connected to an electrical switching device by the plug 8 of the receiving part 7 which is now accommodated in the contact parts 4.
  • FIGS. 5 to 8 A second exemplary embodiment of the plug connector of the multipole plug device is shown in FIGS. 5 to 8. As far as the parts are the same as those of the first embodiment, they have the same reference numbers.
  • the connector 19 in turn has a contact carrier 20 in which contact chambers 3 are formed.
  • the outer wall 12 of the outer rows of contact chambers is also provided with openings 11.
  • the contact parts 4 are arranged, which are attached to the associated ends of the lines forming the wiring harness.
  • the contact carrier 20 is accommodated in a housing of the connector 19 designed as a grip shell 21, from which the cable harness is guided in a manner known per se and not shown in detail.
  • the grip shell 21 surrounds an enlarged end section 23 in the end region of its inner wall 22, which runs parallel to the outer walls 12 of the rows of contact chambers.
  • the contact carrier 20 has a guide section 24 against which the inner wall 22 of the grip shell 21 bears.
  • two slots 26 are formed in the guide section 24 on each longitudinal side 25 of the contact carrier 20.
  • two recesses 27 running parallel to the slots 26 are formed on the longitudinal sides 25 of the contact carrier 20 outside the pair of slots 26 (FIG. 8).
  • a rib 28, which is formed on the contact carrier 20 and projects parallel to the slots 26, is aligned with the bottom of each recess 27.
  • the ribs 28 are formed on the side of the guide section 24 facing the wiring harness.
  • a short-circuit bridge 29 is arranged on each longitudinal side 25 of the contact carrier 20.
  • the short-circuit bridge 29 consists of spring plate and is essentially comb-like.
  • the spring tongues 30 have a long, approximately V-shaped leg.
  • two guide tabs 32 are bent in accordance with the length of the slots 26 of the contact carrier 20 and the distance of the slots 26 from one another and to the same side of the short-circuit bridge 29 as the legs of the spring tongues 30.
  • Via the back 31 of the short-circuit bridge 29 protrude two retaining tabs 33, which correspond in spacing and width to the recesses 27 of the contact carrier 20.
  • the free end of the retaining tabs 33 is bent as a latching lug 34 to the same side as the guide tabs 32.
  • the short-circuit bridges 29 are releasably attached to the contact carrier 20.
  • the guide tabs 32 are inserted into the slots 26 of the contact carrier 20 from the plug-in side of the connector 19, while the retaining tabs 33 guided in the recesses 27 and on the outside of the ribs 28 snap into place with their latching lug 34 at the free end of the ribs 28.
  • the handle shell 21 pushed over the contact carrier 20 rests with its inner wall 22 on the back 31 of the short-circuit bridge 29.
  • the spring tongues 30 of the short-circuit bridge 29 extend into the widened end section 23 of the grip shell 21 and the free legs of the spring tongues 30 protrude through the openings 11 in the outer wall 12 of the outer rows of contact chambers and abut the associated contact parts 4 in the spring chambers 3. As a result, the associated contact parts or contact part pairs 4 are short-circuited when the plug connector 19 is removed (FIG. 7).
  • the spring tongues 30 have such a long spring travel that they can be lifted safely and far enough from the contact parts 4 in the inserted state by the receiving edge 17, 18. Additions of permissible manufacturing tolerances, different thermal behavior of the Materials of the parts and shaking influences during rough operation in motor vehicles do not lead to undesirable short circuits in the plugged-in state of the multi-pole plug device.
  • FIG. 9 shows a modification of the second exemplary embodiment of the plug device 19, 7 according to FIGS. 5 to 8. As far as the parts are the same as those of this device, they have the same reference numbers.
  • the contact carrier 35 has a recess 36 on its longitudinal sides in the region of the guide section 24.
  • At least one pin 38 which can be thermoformed perpendicularly to the longitudinal axis of the contact chambers 3, is formed on both sides of its narrower section 37 bordering the guide section 24.
  • the back 39 of a comb-like short-circuit bridge 40 is bent in such a way that it bears in the recess 35, on the side of the guide section 24 facing the wiring harness side of the modified plug connector 41 and with its free edge 42 on the section 37 of the contact carrier 35.
  • the edge 42 is provided with holes 43 which are aligned with the pins 38 and plugged onto the pins 38.
  • the short-circuit bridge is then non-detachably attached to the contact carrier 35 by riveting the pin end.
