ADAPTER FOR MOUNTING SINGLE- OR MULTI-PIN OVERVOLTAGE PROTECTION DEVICES THAT ARE DESIGNED AS PLUG-IN MODULES, AND USE OF SUCH AN ADAPTER

The invention relates to an adapter for mounting single- or multi-pin overvoltage protection devices that are designed as plug-in modules on a wiring carrier, wherein the adapter has a base and at least one chamber that is open upward and bounded by side walls, from the bottom side of which chamber a plurality of mounting protrusions extend, which each have a contour that is substantially complementary to corresponding openings in the wiring carrier. According to the invention, the mounting protrusions have a hook shape in order to engage under the wiring carrier as a result of sliding of the adapter in the plane of the wiring carrier, after the adapter has been inserted into the openings by means of the mounting protrusions, wherein through-holes are formed in the base, the dimensions of which through-holes allow plug-in connections of the plug-in modules to be fed through to the wiring carrier. Furthermore, metallized holes corresponding to the dimensions of the plug-in connections of the plug-in module are formed in the wiring carrier in such a way that the holes are located congruently with the through-holes in the base after the adapter has been inserted and slid, such that self-securing locking of the combination of the adapter, the plug-in module, and the wiring carrier is provided in addition to electrical contacting, after the plug-in module has been inserted.
