Fastener between electrical apparatus and carrier rails - has flat plug element with two parallel springs and crossbar fitting into socket on apparatus

摘要

To attach electrical apparatus to carrier rails, the apparatus has a slot- shaped socket into which is slid a flat plug element. This has two parallel springs connected to a wedge-shaped latch at the front end and to a crossbar at the rear. The plug is fastened in position by recesses in the sidewalls of the socket, the abutting edge of the handle fitting under a corresponding edge of the socket by elastic deformation of the base rails on either side. To achieve this locking position, and also to disconnect from it, a screwdriver or similar tool is used in an opening on the handle. A connection piece can combine two adjacent fasteners. ADVANTAGE Versatile fastening which can be combined with adjacent fastenings
