Wiring harness plug, especially as planar two-cell limiting current probe having an injection-molded cover element

Abstract

For the adjustment of planar broad-band lambda probes, direct access is obtained to an adjustment element made of a resistor layer applied to a ceramic substrate. For this purpose a corresponding cover element is removed from the probe, or rather, from the probe developed as a wiring harness plug. A cover element is formed directly with the remaining part of wiring harness plug, preferably connected as one piece, and the cover element is made transparent in such a way that a laser beam can penetrate cover element, and processing can occur at adjustment element, even when cover element has already been mounted on wiring harness plug.
