Abstract: Medium or High Voltage Circuit-Breaker Abstract The present invention relates to a medium- or high-voltage circuit breaker (10) comprising a first electric arcing contact (11) and a second electric arcing contact (12) that are axially movable relative to each other between an open position, where the arcing contacts are separated, and a closed position, where the arcing contacts (11, 12) are in contact. The circuit breaker (10) includes an auxiliary nozzle (22) made of a fluorocarbon polymer or of polyeth1ylene, polyamide, polyimide, polyketone, polyacetal, poly1sulfone, polysulfur, which is connected to a support member (20) via a threaded connection (24). To prevent loosening caused by operational vibrations or shockwaves during arc1ing events, the threaded connection is equipped with an anti-loosening mechanism. Various embodiments of the anti1loosening means (25) are disclosed, including a compressi1ble annular member (27) that increases friction between threads, spring- loaded pins (32) interacting with contour pockets (36), elastic ratchets (39) engaging with recesses (41), and an annular brim (47) cooperating with an annular protrusion (45). These mechanisms ensure that the auxiliary nozzle (22) remains securely attached to the support member (20) in a screw-in position, while allowing for easy assem1bly. The invention provides a robust, reliable connection between the auxiliary nozzle (22) and the support member (20), enhancing the performance and durability of the cir1cuit breaker (10) under high mechanical and thermal stress conditions.
