Abstract
A coupler plug, in particular for a planar lambda probe, made up of a housing, i.e., a base element and a cover element, as well as electrical components, which may be placed inside in the housing and fixed in place, and a balancing unit for a probe, in particular a planar broad-band lambda probe, which is to be mounted inside the coupler plug or, via an additional contact element, outside the coupler plug, a secondary locking element being provided as locating element to fixate at least one electrical flat plug-connector placed inside in the housing. In addition to the flat plug-connectors, flat contacts are provided in the plug housing, which are able to be fixed in place simultaneously by means of the secondary locking element, the secondary locking element having, on a first level A, receiving device for the flat plug-connectors in the form of a locking plate, and, on an additional level B, a locating device in the form of a locking hook.
