Embodiment
To accompanying drawing embodiments of the invention are described further below:
Shown in figure, a kind of RCCB comprises housing 1; Be provided with support 2, handle 3, U type bar 4, connecting rod 5, rotating shaft connecting rod 6, flap 7, rotating shaft 8 in the said housing 1 and indicate 9, said handle 3, U type bar 4, connecting rod 5, rotating shaft connecting rod 6, flap 7 are positioned at the inboard of support 2, and the inboard of said support 2 is provided with first fixed axis 10; Said flap 7 is articulated on first fixed axis 10, and said U type bar 4 one ends are connected with handle 3, and an end of the other end and connecting rod 5, rotating shaft connecting rod 6 is hinged; The other end of said connecting rod 5 and flap 7 are hinged, and the other end of said rotating shaft connecting rod 6 and rotating shaft 8 are hinged, and said support 2 is provided with second fixed axis 11; Be hinged with tripping 12 on said second fixed axis 11, described tripping 12 is positioned at the upper end of flap 7, connecting rod 5, and said tripping 12 is provided with the open slot 13 of " L " type; Said flap 7 outer ends are the holding section that inclined plane 71 and cambered surface 72 constitute " L " type; Said holding section and open slot 13 match, and said first fixed axis 10 is hinged with snap close 14, said snap close 14 and tripping 12 clamping matching; Said support 2 is provided with fixed leg 19; Said fixed leg 19 is provided with elastic component 20, and an end of said elastic component 20 is connected with tripping 12, and the other end of said elastic component 20 is connected with snap close 14.According to such scheme, because disconnection or closure that this RCCB adopts the handle 3 of compact conformation to realize contact are simple, convenient; In terms of existing technologies; Also can realize identical functions even omit a plurality of parts, effectively save production cost, improve production efficiency.
In the present invention, shown in figure, said tripping 12 is provided with bending part 121, and said snap close 14 is provided with tip 141, and said bending part 121 blocks formation tripping 12 circumferential spacing cooperations mutually with tip 211.During the closure contact, handle 3 drives U type bars 4 and rotates, and drivening rod 5 and 6 actions of rotating shaft connecting rod; Connecting rod 5 drives flap 7 and rotates counterclockwise, and the inclined plane 71 on the flap 7 affacts on the open slot 13 of tripping 12, drives tripping 12 and rotates; Snap close 14 rotates and tripping 12 screens realization spacing to tripping 12 mutually; Flap 7 rotates till its outer surface circular arc withstands open slot 13 outer surfaces of " L " type of tripping, and rotating shaft connecting rod 6 promotes rotating shafts 8 actions, makes moving contact contact with fixed contact; Simultaneously, rotating shaft 8 drives indication 9 actions.When the electric leakage that detects is threaded off; The push rod of the release on the circuit breaker promotes snap close 14 and rotates counterclockwise; The contact-making surface of tripping 12 and snap close 14 breaks away from, and has destroyed the dead point of quadric chain, thereby makes tripping 12 be rotated counterclockwise to slip away the contact-making surface of flap 7; Flap 7 is also owing to the effect of connecting rod 5 is rotated counterclockwise; Continue to be rotated counterclockwise under the effect of the counterclockwise active force of handle spring with back handle, 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 and is rotated counterclockwise to initial position and presses.
In the present invention; Shown in figure; Said indication 9 comprises indicating section 91, hinge portion 92 and shackle portion 93; Said indicating section 91 matches with indicator hole 15 on the housing 1, and said hinge portion 92 is hinged with the sidepiece of support 2, and said shackle portion 93 matches with rotating shaft 8 to form and indicates 9 to swing.Rotation drive indication 9 through rotating shaft 8 is moved, compact conformation, and action is simple, convenient.
In the present invention, shown in figure, the outside of said support 2 is provided with through hole, and said hinge portion 92 is provided with the jointed shaft 16 that is hinged with through hole.Rotating shaft 8 drives indication 9 and rotates around the through hole on the support 2, and the axle 16 that perhaps on support 2, is fixedly hinged is provided with through hole in indication 9.
In the present invention, shown in figure, the end of said shackle portion 93 is provided with to a side stretches out limited post 17, and said rotating shaft 8 is provided with draw-in groove 18, and said limited post 17 matches with draw-in groove 18 and constitutes rotating shaft 8 and indication 9 circumferential transfer torques.The handle action drives 4 actions of U type bar; U type bar 4 drives 6 actions of rotating shaft connecting rod, and rotating shaft connecting rod 6 drives rotating shaft 8 and rotates, because the limited post 17 in the indication is to be stuck in the draw-in groove 18 of rotating shaft 8; Rotate around through hole thereby make rotating shaft 8 drive indication 9, realize the variation of indication.
In the present invention, shown in figure, said operating mechanism 3 is positioned at the sidepiece of housing 1 upper end.The position at the handle place on the position of this sidepiece and the miniature circuit breaker is identical, so when RCCB and miniature circuit breaker were assembled together, the position of handle is identical, thereby makes harmony better, and was aesthetic in appearance.
Embodiment should not be regarded 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.
