Description
Technical field
The utility model belongs to low tension switch technical field, is specifically exactly to be related to a kind of reliably turning for switch auxiliary contact
Mode is changed, ensure that the reliability of handoff procedure.
Background technique
Low tension switch usually requires electric accessories of the configuration auxiliary contact as switch, and " the dividing " of switch, " conjunction " state can
To pass through electric signal instruction switch by the movement of the normally-open normally-close transition response switch operating mechanism of auxiliary contact
" dividing ", " conjunction " state.
Actuator in traditional auxiliary contact handoff procedure, on multi-pass lever one end really up to the mark and switch operating mechanism
Contact, the other end is contacted with the microswitch on auxiliary contact, thus the division state of search switch, generally, in switch point
In place in a flash, the microswitch on auxiliary contact is converted to normally-closed contact from normally opened contact to lock, but traditional switch exists
There is the case where moving contact rebound when separating brake, microswitch is caused to be converted to normally-closed contact from normally opened contact, then from normally closed touching
Point is converted to normally opened contact, cyclic switching, and until rebound stops, such words passes through the division shape of auxiliary contact acquisition switch
State signal occurs as soon as frequent switching, extremely inaccurate to the signal of client feedback, the electric appliance malfunction that is likely to result on route and
Biggish loss.
The reason of causing above-mentioned phenomenon to occur is to switch during the opening process, the driving auxiliary touching of operating mechanism cantilever drive part
Hard lever, the microswitch on hard lever driving contact contact, make its it is normally opened with it is normally closed between switch.Due to operating mechanism
Drive moving contact together separating brake when, moving contact movement have certain initial velocity and quality, when separating brake encounters limit shaft in place,
Moving contact moves a distance by reaction force pull operation mechanism cantilever, then toward combined floodgate direction, is just struck against in place in separating brake
When limit shaft, contact is switched to normally-closed contact by normally opened contact, but encounters when moving a distance toward combined floodgate direction after limit shaft,
Contact is switched to normally opened contact by normally-closed contact, causes contact switching unreliable.
Chinese patent ZL200810244463.7 discloses a kind of auxiliary switch for circuit breaker, belongs to low-voltage electrical apparatus attachment technique
Field.The shell being fitted to each other including a pair, the microswitch that is located in the shell chamber of shell and the shell chamber for being similarly located at shell
In driving member, constituting on the driving member has the first contact arm of the haptic element for activating the microswitch and composition to have spy

On the upper surface of arm, and the second working face is formed in the auxiliary switch on the top end face of the first contact arm and has protected making for shield microswitch
Use the service life；Reliability of Microprocessor and the safety that microswitch can be improved, finally enable the reliability of auxiliary switch ensure.But
The auxiliary contact is the protection considered when circuit breaker operation mechanism generates overshoot phenomenon to microswitch, on solving
It states since the presence of moving contact rebound phenomena causes microswitch to be converted to normally-closed contact from normally opened contact, then turns from normally-closed contact
Chemical conversion normally opened contact cyclic switching is to make the technical problem of signal inaccuracy.
