Embodiment
For accompanying drawing, embodiments of the invention are described further below:
Shown in figure, a kind of residual current circuit breaker, comprise housing 1, in described housing 1, be provided with support 2, handle 3, U-shaped bar 4, connecting rod 5, rotating shaft connecting rod 6, flap 7, rotating shaft 8 and indication 9, described handle 3, U-shaped bar 4, connecting rod 5, rotating shaft connecting rod 6, flap 7 is positioned at the inner side of support 2, the inner side of described support 2 is provided with the first fixed axis 10, described flap 7 is articulated with on the first fixed axis 10, described U-shaped bar 4 one end are connected with handle 3, the other end and connecting rod 5, one end of rotating shaft connecting rod 6 is hinged, the other end of described connecting rod 5 and flap 7 are hinged, the other end of described rotating shaft connecting rod 6 and rotating shaft 8 are hinged, described support 2 is provided with the second fixed axis 11, on described the second fixed axis 11, be hinged with tripping 12, described tripping 12 is positioned at flap 7, the upper end of connecting rod 5, described tripping 12 is provided with the open slot 13 of " L " type, described flap 7 outer ends are the holding section that inclined plane 71 and cambered surface 72 form " L " type, described holding section and open slot 13 match, described the first fixed axis 10 is hinged with snap close 14, described snap close 14 and tripping 12 clamping matching, described support 2 is provided with fixed leg 19, described fixed leg 19 is provided with elastic component 20, one end of described elastic component 20 is connected with tripping 12, the other end of described elastic component 20 is connected with snap close 14.According to such scheme, because adopting the handle 3 of compact conformation, this residual current circuit breaker realizes the disconnection of contact or closure, and simple, convenient, in terms of existing technologies, even if omit a plurality of parts, also can realize identical function, effectively save production cost, improve production efficiency.
In the present invention, shown in figure, described tripping 12 is provided with bending part 121, and described snap close 14 is provided with tip 141, and described bending part 121 blocks mutually and forms circumferential spacing cooperation of tripping 12 with tip 211.During closed contact, handle 3 drives U-shaped bar 4 to rotate, and drivening rod 5 and 6 actions of rotating shaft connecting rod, connecting rod 5 drives flap 7 to rotate counterclockwise, inclined plane 71 on flap 7 is applied on the open slot 13 of tripping 12, drive tripping 12 to rotate, snap close 14 rotates with tripping 12 phase screens realizations spacing to tripping 12, flap 7 rotates until its outer surface circular arc withstands open slot 13 outer surfaces of " L " type of tripping, and rotating shaft connecting rod 6 promotes rotating shaft 8 actions, moving contact is contacted with fixed contact, and meanwhile, rotating shaft 8 drives indication 9 actions.When the electric leakage detecting is threaded off, the push rod of the release on circuit breaker promotes snap close 14 and rotates counterclockwise, the contact-making surface of tripping 12 and snap close 14 departs from, destroyed the dead point of quadric chain, thereby tripping 12 is rotated counterclockwise slip away the contact-making surface of flap 7, flap 7 is also because the effect of connecting rod 5 is rotated counterclockwise, with back handle, under the effect of the counterclockwise active force of handle spring, continue to be rotated counterclockwise, flap 7 also turns clockwise under the thrust along with connecting rod 5, and elastic component torsion spring 20 drives trippings 12 and snap close 14 to be rotated counterclockwise to initial position and presses.
In the present invention, shown in figure, described indication 9 comprises indicating section 91, hinge portion 92 and shackle portion 93, described indicating section 91 matches with the indicator hole 15 on housing 1, described hinge portion 92 is hinged with the sidepiece of support 2, and described shackle portion 93 matches with rotating shaft 8 to form and indicates 9 to swing.Rotation by rotating shaft 8 drives indication 9 to move, compact conformation, and action is simple, convenient.
In the present invention, shown in figure, the outside of described support 2 is provided with through hole, and described hinge portion 92 is provided with the jointed shaft 16 being hinged with through hole.Rotating shaft 8 drives indication 9 to rotate around the through hole on support 2, or the axle 16 that is fixedly hinged on support 2, in indication 9, through hole is set.
In the present invention, shown in figure, the end of described shackle portion 93 is provided with to a side stretches out limited post 17, and described rotating shaft 8 is provided with draw-in groove 18, and described limited post 17 matches with draw-in groove 18 and forms rotating shaft 8 and indication 9 circumferential transmitting torques.Handle action drives U-shaped bar 4 actions, U-shaped bar 4 drives 6 actions of rotating shaft connecting rod, and rotating shaft connecting rod 6 drives rotating shaft 8 to rotate, because the limited post 17 in indication is to be stuck in the draw-in groove 18 of rotating shaft 8, thereby make rotating shaft 8 drive indication 9 to rotate around through hole, realize the variation of indication.
In the present invention, shown in figure, described operating mechanism 3 is positioned at the sidepiece of housing 1 upper end.The position of this sidepiece is identical with the position at handle place on miniature circuit breaker, so when residual current circuit breaker and miniature circuit breaker are assembled together, the position of handle is identical, thereby makes harmony better, aesthetic in appearance.
Embodiment should not be considered as the restriction to invention, but any improvement of doing based on spirit of the present invention, all should be within protection scope of the present invention.
