LOCKING MECHANISM WITH MOVING SPINDLE Russian patent published in 2010 - IPC H01H71/52 

FIELD: mechanics.

SUBSTANCE: invention is a breaker consisting of at least a single movable contact (4) intended for interaction with one or more stationary contacts (12). The mechanism (1) switches over between the fixation position for coupling and defixation position for decoupling of lines and controlled by an electrical device, an executive tool (2) which enables variation of the mechanism (1) position to control it depending on any decoupling caused by appearance of at least a single line of electrical conditions incompatible with its coupling. The executive tool (2) is connected to the locking mechanism (1) via a link rod (3). Each movable contact (4) is rigidly connected to the contact retainer (17) while the flexible elements (6b, 16) for pressure provision, retaining each movable contact (4) on a stationary contact (12), are connected to the contact retainer (17) c with the help of a link (7b; 21, 22) providing for movement of the first turn axle relative to the support area(s) of the movable (4) and the stationary (12) contact in case of pressure occurrence.

EFFECT: simplification of the locking mechanism and its assembly in devices with exclusion of the necessity to set the locking mechanism when placed inside a housing.
