Description
Technical field
This utility model relates to a kind of RCCB, and especially a kind of service life is long, the RCCB that reliable operation degree is high.
Background technology
RCCB refers to close, carry and cut-off the electric current under normal loop condition the switching device of electric current that can close, carry within the time of regulation and cut-off under abnormal loop condition.RCCB generally includes contact system, arc quenching system, operating mechanism, electrical apparatus release, shell etc. and constitutes.Wherein, operating mechanism includes again connecting rod, connector, fastener completes a series of dropout or connecting moves again, but in existing RCCB, there are the following problems, 1, tripping and again button between annexation the most unstable, and on the other hand its connection is also arc surface, skidding can often occurs, cause RCCB the most unstable and unreliable after so arranging.2, detaining owing to being easily deformed under gravity and high-temperature condition, button deforms and will affect the use of whole RCCB more again.
Summary of the invention
It is long for service life that problem to be solved in the utility model is to provide one, the RCCB that reliable operation degree is high.
For solving above-mentioned technical problem, including housing, the contact system be located in housing, arc quenching system, operating mechanism, described operating mechanism includes the connecting rod being connected with contact, the tripping being socketed in connecting rod and be connected with connection-rod linkage, and the detaining again of contacting of leaning with tripping one end, described tripping is connected respective joint face with button again and leans, the described again joint face that button leans with tripping is provided with the first connector, described tripping and detain the joint face leant again and be provided with second connector suitable with the first connector.
After have employed said structure, owing to each adding the first connector and the second connector on joint face, technology effect of locking is added so that in operation, its stability and reliability are all greatly increased RCCB on the basis of originally relying only on plane-plane contact.
As further improvement of the utility model, described first connector is the groove being arranged on the joint face that button and tripping lean again, described second connector is to be arranged in tripping and the most advanced and sophisticated projection suitable with groove, described most advanced and sophisticated protruding shape and size arrange and are placed in groove, and groove is that inclined-plane coordinates with tip projection.
After have employed said structure, owing to the first connector and the second connector are inclined-plane and tip projection, coordinated by inclined-plane and not only instead of the technical barrier that the cooperation of original cambered surface is easily skidded, and the setting of groove and tip projection also considerably increases fastening effect.
As further improvement of the utility model, described connecting rod includes two sleeving connecting rods being separated by setting, described button again is arranged at being separated by space of two sleeving connecting rods, described sleeving connecting rod side is additionally provided with second consistent with the abutment face shape buckling button and tripping more again buckle side again, described second again buckle side with detain inclined-plane again and be in same level, and the most advanced and sophisticated projection of tripping can lean with button and second buckle side more simultaneously.
After have employed said structure, two abutment faces are utilized to define dual fail-safe, and but two abutment faces are to be connected mutually with gangbar split setting, during when one of them abutment face because high temperature or gravity reason are damaged, another one abutment face also can ensure the normal work of RCCB.

Detailed description of the invention
As shown in Figure 1, including housing 1, the contact system be located in housing, arc quenching system, operating mechanism, described operating mechanism includes the connecting rod 2 being connected with contact, the tripping 3 being socketed in connecting rod and be connected with connection-rod linkage, and lean with tripping 3 one end contact detain 4 again, described tripping 3 with detain 4 again and be connected respective joint face and lean, described 4 joint faces leant with tripping 3 of detaining again are provided with the first connector 5, described tripping with detain the joint face leant again and be provided with second connector 6 suitable with the first connector.Owing to each adding the first connector 5 and the second connector 6 on joint face, on the basis of originally relying only on plane-plane contact, add technology effect of locking so that in operation, its stability and reliability are all greatly increased RCCB.Described first connector 5 is the groove 51 being arranged on the joint face that button and tripping lean again, described second connector 6 is for being arranged in tripping and the most advanced and sophisticated projection 61 suitable with groove 51, the described most advanced and sophisticated shape of protruding 61 and size arrange and are placed in groove 51, and groove is that inclined-plane coordinates with tip projection.Owing to the first connector and the second connector are inclined-plane and tip projection, are coordinated by inclined-plane and not only instead of the technical barrier that the cooperation of original cambered surface is easily skidded, and the setting of groove 51 and tip projection 61 also considerably increases fastening effect.
As shown in Figure 2, described connecting rod includes two sleeving connecting rods 7 being separated by setting, described button again is arranged at being separated by space of two sleeving connecting rods, described sleeving connecting rod side is additionally provided with second consistent with the abutment face shape detaining button and tripping again on 4 again buckle side 8 again, described second again buckle side 8 with detain inclined-plane again and be in same level, and most advanced and sophisticated protruding the 61 of tripping can lean with button and second buckle side more simultaneously.Utilizing two abutment faces to define dual fail-safe, and but two abutment faces are to be connected mutually with gangbar split setting, during when one of them abutment face because high temperature or gravity reason are damaged, another one abutment face also can ensure the normal work of RCCB.
