Description
Technical field
The utility model belongs to microswitch, and more particularly to a kind of band is forced to detach universal microswitch.
Background technology
Microswitch is equivalent to standard component and uses on the market on existing market, and all microswitches can not all be realized substantially
Separation is forced, the reason is as follows that：
1st, microswitch overall structure size is small, and switch internal narrow space, inner space component structure is compact, is opening
Closing the constant situation switch of mounting hole dimensional standard can not do greatly, basic it is difficult to which additional again increase pressure separation member.
2nd, largely by tension spring, reed or monoblock type shrapnel Self-resetting, original state usually switchs dynamic tactile microswitch
Piece upper contact contacts above with normally closed connector upper contact, forces separation member mostly using seesaw motion mode come real in switch
Now switch forces separation, and when movable contact spring upper contact contacts above with normally closed connector upper contact, button pressed downwards trigger in the process
Separation member one end is forced to be moved downward around fulcrum, it is upward to force the separation member other end direction of motion, and forces separation member only
Pressure separation function can just be played by being acting downwardly on movable contact spring, therefore it is to be upwards to force the separation member other end direction of motion
It does not work, this also causes microswitch to be difficult to realize pressure separation function.
3rd, mostly using tension spring, reed or monoblock type shrapnel trigger switch power on/off, switch moves microswitch inner elastomeric part
Make with resetting all by elastic component completion, elastic component elastic force is generally smaller, and separation member is forced if increased in inside, forces to divide
Off member oneself can not reset, and need to make its reset, but the universal power of microswitch elastic component elastic force is less than normal by switch shrapnel elastic force, need
Power additionally to be separated for separation member to be forced to reset, elastic component burden is increased, easily influences switch action characteristic, switch elastic force
Attenuation, serious situation can cause switch motion to be failed, if forcing separation member vibration during switch installation environment vibration environment
Also it is easy to cause and goes wrong.
4th, when microswitch uses reed or monoblock type shrapnel, because movable contact spring wall thickness itself is thin and flexible, work as pressure
When separation member acts on flexible movable contact spring, because microswitch actuating length is all shorter, movable contact spring flexible deformation is offset
The effect of pressure separation member can cause separation member is forced not work, and solve the problems, such as that this needs to increase switch total kilometres, but micro-
The dynamic switch confined space does not allow to be further added by stroke, and otherwise switch reforms into nonstandard switch, even if allowing to increase switch total kilometres,
Because microswitch is largely resetted by reed or monoblock type shrapnel, total kilometres increasing, which can cause movable contact spring to be disengaged from the groove, to be caused to switch nothing
Method acts.Even if movable contact spring does not fall piece, because gap is smaller between microswitch sound contact, separation is forced to be made when switch touches
It is big used in elastic movable contact spring up stroke, movable contact spring permanent deformation is also easy to cause, movable contact spring can lead to shape once being permanently deformed
Variation, change in shape so that cause movable contact spring position of the fulcrum variation lead to switch motion Parameters variation, can seriously cause switch nothing
Method is acted or is resetted.
Some above problem causes to be substantially not visible same type in the market or similar microswitch has pressure separation function,
Belong to microswitch industry bottleneck, switch does not have pressure separation function, when there are abnormal conditions in switch, dynamic and static contact by
Button can not be detached normally during pushing, and bring severe compromise sometimes, because existing microswitch can not realize pressure point
From, therefore the field for having safety requirements can not be applied, especially there are professional standard industry, such as elevator industry etc. at some.Cause
Switch application is severely limited, restricts industry development.
