ARCING CONTACT TULIP WITH FLOW OPTIMIZED SLITS AND INTEGRATED STRESS RELIEF FEATURE

摘要

A tulip contact for a power switch, comprises a rotationally symmetric contact body 100 having a first end 120, a second end, and a plurality of slits 210, 220. The slits are arranged in the body and extend parallel to the symmetrical axis 140 of the body. The slits define a length between the first end and a root of the slits.The slits have a first width at the first end and a second width at the root of the slits, wherein the first width is bigger than the second width. A stress-relief element 400 is provided to mitigate mechanical stress in the material of the body 100 in case the slits 210, 220 close.
