INSULATING NOZZLE AND ELECTRICAL SWITCHING DEVICE COMPRISING THE INSULATING NOZZLE

摘要

Insulating nozzle (1) for an electrical switching device (14) and electrical switching device (14) comprising the insulating nozzle (1), comprising a first inner region on a first side (3), configured to receive a first electrical contact part (15), and a second inner region on a second side (4), configured to receive a second electrical contact part (16). The second contact part (16) can be arranged moveably with respect to the first contact part (15). The insulating nozzle (1) further comprises a through-channel (5), arranged in a region between the first and second inner regions, configured as a narrowing of the insulating nozzle (1). The channel (5) has at least two different regions (8, 9) having different cross-sections from one another.
