Definitions

  • Coupling plugs of the above type are usually for the connection formed between a harness connector and a lambda probe, the connections provided in the coupling plug being for adjustment, Signal and / or heating of the probe are provided.
  • the lambda probe and the lambda control provide today in conjunction with the 3-way catalytic converter an effective emission control method.
  • the lambda probe which is screwed, for example, in an exhaust system, includes a Sensor for determining the oxygen content in the exhaust gas.
  • the residual oxygen content is very suitable as a measured variable and regulates the air-fuel ratio, as this indicates precisely whether the air-fuel mixture completely burned.
  • the lambda probe supplies a voltage signal that is the current one Value of the mixture composition represented and the mixture changes follows.
  • heated or unheated probes used find more applications the lambda probe outside of fuel vehicles, eg. B. for regulation of gas engines or oil / gas burners.
  • broadband lambda probes are modular and allow in conjunction with the planar technology, the integration of several functions. They usually have functional layers made of a porous Protective layer, comprising an outer electrode, a sensor foil, an inner electrode, a reference air channel foil, an insulating layer, a Heating element, a heating foil, a resistor or a balancing element and connecting contacts exist.
  • a porous Protective layer comprising an outer electrode, a sensor foil, an inner electrode, a reference air channel foil, an insulating layer, a Heating element, a heating foil, a resistor or a balancing element and connecting contacts exist.
  • each probe is to be adjusted individually.
  • the probe has a built-in resistor ("mini-hybrid") on.
  • the balance preferably is carried out by means of a laser beam, is carried out by that Resistor layer, which is located on a ceramic substrate, accordingly is removed, causing a change in resistance and thus an adjustment takes place.
  • the balancing unit or the Resistor is arranged directly on the probe.
  • the resistance outside for example accommodated on a harness connector coupled to the probe is.
  • the adjustment is carried out in that the housing of the coupling plug, in which the resistor is installed, without the cover element for Matching point is transported. After the appropriate laser processing for the adjustment was then followed by another mounting point the cover element plugged.
  • the cover element After attaching the lid member, it is for both the supplier the coupling plug as well as the user possible, the cover element to remove and possibly perform a further adjustment or perform manipulations on the coupling plug itself.
  • a coupling plug for a planar lambda probe according to the preamble of claim 1 is off WO 0245212, published June 6, 2002
  • the object of the invention is an embodiment of the coupling plug, in particular for a planar broadband lambda probe is provided in such a way that it can be produced very inexpensively is and has a Kontrolluflementionslement, by means of easy way to determine whether the lid member by third unauthorized has been removed or not.
  • An essential advantage of the invention is that the present invention proposed coupling plug designed cloved is because of the compact design, namely the insertion of electrical Contacts in a body and the arrangement of the adjustment element also in the coupling plug, the outer dimensions of the coupling plug, preferably between a wire harness and a Lambda probe is arranged, are very small.
  • Coupling plug has only a few components. This is a cost-effective and efficient production possible.
  • this also supports the locking of the lid member to the Body.
  • a front and a final latch or a Primary and a secondary locking provided.
  • This is designed in such a way that the cover element has latching arms, which are in the closed Apply condition of the cover to the body of the coupling plug and there catch with latching noses a catch.
  • This primary locking takes place in two stages.
  • a first stage locks the lid member such that it is held on the body becomes.
  • the lid member By further pressing the lid member in the direction of Base body is caused that the inserted in the body fixing on the guided in the body electrical contact element, For example, a flat plug sleeve, in conjunction with the Lambda probe is stationary, is fixed.
  • the fixation takes place only in the Form that the fixing element is pressed onto the contact element, so that the contact element and the fixing element form a firm connection.
  • the fixing element is forcibly guided in the basic body, this means that in the fixed state of the contact element, the fixing element only move in the axial direction of attachment of the lid can.
  • These control elements engage in the functional state a hold-down fixed to the body of the coupling plug connected is.
  • the longitudinal movement of the secondary lock in limited the type that the fixing element only in the direction of the body can move. Is the installation of the secondary locking system incorrect? takes place, so are the control elements on the hold-down and the fixing can not be by pressing down the lid member move in the direction of the body. This can be done immediately be found that still no functional installation of secondary locking is done.
  • the support elements are so far over the main body of the coupling plug addition, that the cover element only in the first latching of the primary latch. Just with complete actuation and thus correct fixation of the contact element the cover element also passes the second latching of the primary latch one.
  • a further advantage of the invention is that the aforementioned Seals can be molded onto the lid member, so that these are arranged captive.
  • the cover element consists of PBT (polybutylene terephthalate) or equivalent materials.
  • a further advantageous embodiment of the invention is that the cover element is designed to be transparent. That's it possible that the cover element are already mounted before the adjustment can, as with transparent cover elements of the balance by means of a Laser beam can be done through the lid member therethrough.
  • coupling plug 1 is itself to such a plug, which consists of a housing 2 that composed of a base body 3 and a cover element 4.
  • a balancing unit 6 On the base body 3 is in a holding device 5 is a balancing unit 6, which in turn via electrical contact elements 7 with the connected via a connecting element 8 lambda probe or with the over the inserted into the coupling connector 1 and in the drawings not shown plug is connected.
  • the electrical contact elements 7 are made of a track similar shaped Metal strips which are in the area of the coupling possibility 9 (FIG. 4) of the coupling plug 1 ends with its one side.
  • the adjustment unit 6 is about guide elements 10, the largest Part are arranged on the base body 3, guided and by the electrical Contact elements 7 held in position.
  • the fixing element 12 is provided as a secondary locking element and has the function of an arranged in the housing 2 electrical Contact 13, in particular associated with the lambda probe, to keep in position.
  • the fixing element 12 is preferably W-shaped in its cross section formed, being it axially between its two legs 12a / 12b in the assembled state ( Figure 7) includes the electrical contact 13.
  • the secondary locking element or the fixing element 12 is also designed such that this preferably with the support elements 11th forms an integral part.
  • each Legs 12a, 12b control elements 20 arranged in the in 9 and 10 embodiment shown perpendicular to this stand out and form nose-like bulges.
  • These control elements 20 engage in a hold-down 21, which directly with the housing. 2 the coupling plug 1 is connected.
  • the hold-down 21 has a Recess 22, in which the control element 20 of the fixing element 12th engages, provided the secondary lock is installed correctly.
  • the coupling plug 1 has grooves 14 at its periphery, which allow a coupling plug 1 in designated holder insert.
  • the holding element 15 is formed like a clip, so that the coupling plug 1 in the open position of the holding element 15 on a Harness can be plugged, and by means of another movement this can then be closed.
