Tensioning arrangement e.g. for compression or draw-spring of low voltage (LV) power switch

摘要

The arrangement includes a latching wheel arranged on a tensioning shaft, which is turned gradually in a rotation direction by device of a transport latch activated through a tensioning lever. The latch wheel tensions during its rotation over lever drive the arrangement up to a locking of a lock arrangement which is released for switching. A reverse turn of the latch wheel is prevented through a pawl. A control disk (9) moving together with the latch wheel (5) is arranged on the tensioning shaft (1). The control disk has a concentric contour over the largest part of its extent, and a nose (10) projecting above the concentric contour over the remaining part of its extent. The transport latch (4) comprises a control pin (11) which engages with the control disk.
