Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is the configuration diagram of the utility model under off-state;
Fig. 2 is the configuration diagram of the utility model in closing course;
Fig. 3 is the configuration diagram of the utility model under closure state.
As shown in the figure, the utility model comprises housing 16, is provided with electromagnetic trip device in housing 16, fixed contact 17, moving contact 11, snap close 15, tripping 4, handle 1 and kinematic link 2.Fixed contact 17 links to each other with the coil of tripgear and together is fixed in the housing 16 with tripgear, moving contact 11 be located at fixed contact 17 corresponding positions on, be provided with opening and small column in the upper end of housing 16, handle 1 passes opening and is installed in a spiral manner on the housing 16 by small column and housing 16 hinged handle springs 3, its other end is fixed on the handle 1 and makes handle 1 deflection open position, kinematic link 2 one ends and the handle 1 hinged other end and tripping 4 are hinged, in housing 16, also be provided with snap close 15 and release lever 12, snap close 15 is hinged in the housing 16 by snap close axle 5, latch spring 8 is installed in the below of snap close 15 in a spiral manner, the one end is fixed on snap close 15 " L " the shape barb, the other end is fixed on " L " shape barb of support 6 belows, in the middle of the support 6, hinged by snap close axle 5 and snap close 15, the bottom is hinged by rivet 14 and moving contact 11, top is hinged by rivet 7 and tripping 4, extension spring 10 1 ends are held moving contact 11 tops, make the tip side of moving contact 11 rely on contact 21 1 sides of fixed contact 17.Extension spring 10 other ends are pulled on the axle 9 that is fixed in the housing 16.Also be provided with a push rod spring 19 on housing 16, push rod spring 19 1 ends withstand on moving iron core 18 inboards, and the other end withstands on skeleton 20 outer ends, and moving iron core 18 pulls to push rod 22 at an end of snap close 15.
Under off state (Fig. 1), the position that handle 1 is opened circuit by handle spring 3 pressed rightwards, at this moment, the elbow that connects the kinematic link 2 of handle 1 inserts in the hole of tripping 4, makes tripping 4 under the effect of latch spring 8, temporary transient realization is hinged with snap close 15, moving contact 11 leaves fixed contact 17 under extension spring 10 effects simultaneously, and at the push rod 22 of tripgear, push rod spring 19 effects down, make iron core 18 to left movement, push rod 22 is in no stress; Release lever 12 is in the centre position of snap close 15 circular arcs, during with the operating mechanism closure (Fig. 2), handle 1 is pulled toward closed position.Handle 1 rotates tripping 4 by kinematic link 2, and drive snap close 15, support rotates moving contact 11 is moved toward fixed contact 17 directions, and extension spring 10 stops moving contact 11 to move to fixed contact 17, extension spring 10 will be elongated like this, continue to pull handle 1, handle 1 is turned to closed extreme position (Fig. 3), this moment, handle 1 was crossed with the hinged dead point of kinematic link 2, cross the dead point and handle spring 3 the power on the handle 1 of acting on is not enough to overcome handle 1, thus handle 1 fix at this extreme position, under this state, moving contact 11 is being pressed under the effect of extension spring 10 on the fixed contact 17, and the lower end of snap close 15 is near the push rod 22 at tripgear.The position of release lever 12 in snap close 15 is in the circular arc end.When short circuit current, moving iron core 18 on the tripgear will overcome the resistance of push rod spring 19, push rod 22 is pushed to the lower end of snap close 15, the resistance that overcomes push rod spring 19 simultaneously makes snap close 15 do the limited tripping 4 that is rotated away from counterclockwise, the snap close 15 and the hinged relationship of tripping 4 are removed, this moment, snap close 15 was got back to original position under the effect of latch spring 19, and moving contact 11 is in the position under the effect of extension spring 10, when handle 1 is moved back under the effect of handle spring 3 and disconnects.When overload, two gold pulling release levers 22 make 15 inverse times of snap close clockwise moving, and course of action is identical during with short circuit current.
