Definitions
- the invention relates to a coupling plug, in particular for a planar lambda probe, consisting of a housing, namely a base body and a Deckelele- ment and electrical components that can be inserted and fixed in the housing and a balancing element for a probe, in particular a planar broadband Lambda probe which is to be mounted in the coupling plug or via a further contact element outside the coupling plug, wherein a secondary locking element is provided as a fixing element for fixing at least one inserted in the housing electrical tab.
- Coupling plugs of the above type are usually for the connection between a harness connector and a lambda probe formed, wherein the terminals, which are provided in the coupling plug, are provided for adjustment, signal and / or heating of the probe.
- the lambda sensor and the lambda control in conjunction with the 3-way catalytic converter represent an effective exhaust gas purification process.
- the lambda probe which is screwed into an exhaust system, for example, includes a sensor for determining the oxygen content in the exhaust gas.
- the residual oxygen content is very well suited as a measure and regulates the air-fuel ratio, as it indicates precisely whether the air-fuel mixture burns completely.
- the La bda probe supplies a voltage signal that represents the instantaneous value of the mixture composition and tracks changes in the mixture.
- heated or unheated probes are used. Further applications finds the lambda probe outside of motor vehicles, eg. As for the control of gas engines or oil gas burners for heating systems.
- broadband lambda probes have a modular design and, in conjunction with the planar technology, allow the integration of several functions.
- they have functional layers which consist of a porous protective layer, 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 connection contacts.
- each probe is to be adjusted individually.
- the probe has a built-in resistor (mini hybrid).
- the adjustment which preferably takes place by means of a laser beam, is carried out by removing the resistance layer, which is located on a ceramic substrate, in a corresponding manner, whereby a resistance change is brought about and thus an adjustment takes place.
- the adjustment unit or the resistor is arranged directly on the probe.
- the resistor is accommodated outside, for example, on a harness connector coupled to the probe.
- the coupling plug has sealing elements, for example arranged on the plug Cover element or additionally provided pressure compensation elements.
- Coupling plugs of the above type can be made in many forms. As a rule, these are multi-pole coupling plugs which have corresponding tabs.
- a disadvantage of the last-mentioned embodiment of coupling plugs is that additional working and assembly steps are necessary in order to carry out a corresponding fixation by means of a secondary locking of both tabs and flat contacts.
- the object of the invention is to avoid the disadvantages of the cited prior art.
- a significant advantage of the inventive solution is that with a single component locking in two different levels can be brought about.
- the secondary lock according to the invention is a one-piece component. This also reduces the storage and storage of the components and increases the number of possible coupling plug designs, without even increasing the number of components.
- Fig. 1 is a perspective view of the embodiment of a secondary lock according to the invention
- FIG. 2 shows a perspective view of a coupling plug with the secondary lock according to the invention according to FIG. 1, in an exploded view;
- FIG. 3 shows a longitudinal section through a coupling plug according to FIG. 2;
- FIG. 4 shows a cross section through the coupling plug according to FIG. 2;
- FIG. 5 shows a further cross section through the coupling plug according to FIG. 2, the secondary locking being in a pre-locking division
- FIG. 6 shows a further cross section through the coupling plug according to FIG. 2, the secondary locking being in an end position
- Fig. 7 is a longitudinal section through a coupling plug according to
- FIG. 8 shows a partial cross section through the coupling plug according to FIG. 7, wherein the secondary locking shown here is in a pre-locking division;
- FIG. 9 shows a partial cross section through the coupling plug according to FIG. 7, wherein the secondary lock shown here is in an end position.
- FIG. 1 the secondary lock 1 according to the invention is shown.
- This secondary lock 1 comprises two levels A, B, wherein in the first plane A, a locking plate 2 is provided, which can receive 3 record tabs, which are not shown in detail in the drawing by recording device and fix.
- a snap hook 4 pointing away from the locking plate 2 is provided.
- This snap hook 4 serves to fix the flat contacts, not shown in detail in the drawing, which pass through the opening 5 through the locking plate.
- the secondary lock 1 is a one-piece plastic tip casting. This secondary latch 1 is inserted according to FIGS. 2 to 4 in a plug housing 6 of a coupling plug K, in particular to secure tab 7 and flat contacts 8, which are arranged within the plug housing 6.
- a contact carrier lower part 9 to be inserted, which cooperates with the secondary latch 1.
- a balancing resistor 10 is arranged, which is protected by a lid 11 together with a seal 12 from dirt, moisture or the like (in Fig. 3, the lid 11 and the seal 12 for clarity reasons not shown).
- the secondary lock 1 according to the invention is shown in a so-called pre-locking position. This pre-locking position is achieved immediately after the assembly of the coupling plug K shown in FIGS. 2 to 4, and the illustrated tabs 7 are spaced from the secondary lock 1. By moving the secondary lock in the direction of arrow 13, the immediate locking is brought about by taking the end position of the secondary latch 1 and the individual flat plug 7 are fixed.
