Description
Technical field
The present invention relates to a kind of microswitch, more particularly to a kind of band to force the microswitch of separating mechanism.
Background technology
Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power
The contact mechanism of work, is covered with shell, there is a kind of switch of frizzen outside it, because the contact spacing of its switch is smaller,
Therefore named microswitch.Outer mechanical force is acted on power on action reed by actuated element (push-piece, button, lever, roller etc.),
Produce snap action when acting reed and being displaced to critical point, make the movable contact of action reed end and fixed contact quick-make or
Disconnect.After the active force on actuated element is removed, action reed produces counteragent power, when actuated element reverse stroke reaches
After the action critical point of reed, counteragent is instantaneously completed.The contact spacing of microswitch is small, actuating length is short, by power it is small,
Break-make is rapid.The responsiveness of its movable contact is unrelated with actuated element responsiveness.
Traditional microswitch includes housing, panel, normally opened connector, normally closed connector, public connector and normally opened
The dynamic slide plate switched between patch piece and normally closed connector, the single shell fragment or Single spring of dynamic slide plate action are driven, at present on the market
The microswitch used can not meet that many professional standards will because the limitation of its own structure can not realize pressure separation function
Ask, it is impossible to used in the higher occasion of safety coefficient requirement or field.
Microswitch commercially uses equivalent to standard component on existing market, but be substantially all can not for all microswitches
Realize and force separation, its reason is as follows：
1. microswitch overall structure size is small, 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, and basic is difficult again extra increase pressure separation member.
2. microswitch largely leans on extension spring, reed or monoblock type shell fragment Self-resetting, original state generally switchs dynamic tactile
Piece upper contact contacts up with normally closed connector upper contact, forces separation member more using seesaw motion mode come real in switch
Now switch forces separation, when movable contact spring upper contact contacts up with normally closed connector upper contact, triggered during button pressed downwards
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
Do not work, this also causes microswitch is difficult to realize to force separation function.
3. microswitch inner elastomeric part uses extension spring, reed or monoblock type shell fragment trigger switch power on/off more, switch moves
Make all to complete by elastic component with reset, elastic component elastic force is generally smaller, if internally separation member is forced in increase, forces to divide
Off member oneself can not be resetted, it is necessary to make its reset by switch shrapnel elastic force, but the universal power of microswitch elastic component elastic force is less than normal, needed
Additionally to separate power to be used to force separation member to reset, add elastic component burden, easily influence switch action characteristic, when switch bullet
Power decays, and serious situation can cause switch motion to be failed, and forces separation member to shake during vibration environment if switch is arranged on to have
It is dynamic also easily to cause to go wrong.
4. microswitch uses reed or monoblock type shell fragment, 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 elastic deformation is offset
The effect of pressure separation member, it can cause to force separation member not work, to solve this problem 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 increase switch total kilometres,
Because microswitch largely resets by reed or monoblock type shell fragment, total kilometres, which increase, can cause movable contact spring can not reset or take off groove
Switch is caused not act.Even if movable contact spring does not fall piece, because gap is smaller between microswitch sound contactor gap, when opening
Close and force centrifugation big in elastic movable contact spring up stroke, also easily cause movable contact spring to be permanently deformed, movable contact spring is once permanent to be become
Shape can cause change in shape, change in shape and then cause movable contact spring position of the fulcrum to change, and cause switch motion Parameters variation, seriously
Switch can be caused can not to act or reset.
Some problem causes in the market to be substantially not visible same type or possesses pressure separation function similar to microswitch above,
Belong to microswitch industry bottleneck, switch does not possess pressure separation function, when there are abnormal conditions in switch, dynamic and static contact by
Button can not be separated normally during pushing, and bring severe compromise sometimes, because existing microswitch can not realize pressure point
From, therefore it can not apply and have the field of safety requirements, especially have an industry security standards industry at some, such as elevator industry
Deng, cause switch application severely limited, restrict industry development.
