摘要

One of the connected parts has a slot (N) on the edge of an upper side (OS). The slot is covered by a lamella (L) which pref. forms an extension of the upper side. The second part (B1) has a bladelike insertion region . After the insertion region of the second part is inserted into the slot in the first part, burrs (P1) are formed in the region of the lamella in the surface of the first part. USE/ADVANTAGE - Esp. for fixing rail with cover plate on screened carrier for holding electronic assemblies. Enables screened fixing to be performed more simply.
