Description
Technical field
This utility model relates to a kind of press button.
Background technology
Button switch has following defects that one is without power-off restarting defencive function in the market.When connecting electrical work, occur power-off or attaching plug to be pulled out by other people by mistake, operator is also in and presses during switch key makes electrical appliance, the most suddenly send a telegram here or switch on power, conducting motor work rapidly in the case of operator is not vigilant, impulsive force during electric motor starting easily causes the injury of operator and the damage of electrical equipment.Two is to use controllable silicon to combine single-chip microcomputer element to realize defencive function.But the method reliability is low, and cost is high.Main cause has: electrical equipment uses for a long time or over loading uses, and temperature of silicon controlled rectifier constantly raises, and easy electrical breakdown burns, and loses defencive function；Single-chip microcomputer auxiliary electronic element is various, electronic component destructible or come off under adverse circumstances (very hot, the coldest), loses defencive function, even there is potential safety hazard.So some higher-end businesses do not approve this protection scheme, even resist.
Chinese patent once disclosed the press button (CN201420837169) of a kind of band power-off protection; including press button body; described press button is the most internal is integrated with power failure protection module; each being connected to switch contact and power failure protection module on biphase power transmission line, described power failure protection module is in parallel with described switch contact by signal spring；Described signal spring detects the input by monitoring switch contact and the contrast of output voltage; determine whether that voltage passes through described switch contact; and send a signal to described power failure protection module; if described power failure protection module receives voltage passes through the signal of described switch contact, the most described power failure protection module keeps voltage conveying；If described power failure protection module receives the signal not having voltage to pass through described switch contact, the most described power failure protection module cuts off voltage conveying.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art to exist; the press button that a kind of band power-off restarting is protected is provided; it can be under normal work conducting state; burst power-off is sent a telegram in reply again; operator needs to decontrol switch key so that it is reset completely, and the most again pressing switch key can turn-on power; start electric equipment products work, otherwise cannot turn-on power.
For reaching above-mentioned purpose; the solution that this utility model is taked is: the press button of a kind of band power-off restarting protection; it includes button and circuit; circuit arranges normally open contact K1, normally closed interlock K2; normally open contact K1 moved end meets inductive electromagnetic mechanism KM one end and power supply L; normally closed interlock K2 moved end connects from even circuit KM1 moved end and power supply N; normally open contact K1 quiet termination motor M one end; motor M another termination inductive electromagnetic mechanism KM other end, the quiet end of normally closed interlock K2, normally open at the even quiet end of circuit KM1, the most even circuit KM1；Normally open contact K1 is turned on or off with button with normally closed interlock K2, when pushing button, before normally open contact K1 conducting, normally closed interlock K2 is bound to disconnect, and decontrols button, after first disconnecting normally open contact K1, normally closed interlock K2 could turn on, and inductive electromagnetic mechanism KM obtains electric, from even circuit KM1 adhesive, operating current turns on, and could continue adhesive work from even circuit KM1 Guan Bi inductive electromagnetic mechanism KM.
In this kind of band power-off restarting realizes the press button of protection, normally closed interlock K2 is the activate switch of inductive electromagnetic mechanism KM.When LN switches on power, being worked by normally closed switch K2 Dai Tong inductive electromagnetic mechanism KM, from even circuit KM1 Guan Bi, then operate button, the normally open contact K1 that is turned on or off realizes work or the stopping controlling motor M.When power-off is sent a telegram in reply again, power-off i.e. inductive electromagnetic mechanism KM dead electricity, disconnect from even circuit KM1, motor M also stops power supply, after telegram in reply, but normally open contact K1 is also under closed action state, and motor M cannot start, because also locating in the off state from even circuit KM1, need operator's reset switch button, disconnected normally open contact opens K1, connects normally closed interlock K2, and inductive electromagnetic mechanism KM could obtain electric, from even circuit KM1 Guan Bi, operator presses switch key again, and normally open contact K1 closes, and motor M could normally work.Thus realize the prompting to operator and protection.
This switch is a kind of mechanical keyswitch, presses connection, decontrols and disconnects.When switching manipulation switches on power work, when power-off is sent a telegram in reply again, operator need decontrol switch key so that it is reset completely, the most again press switch key can turn-on power, start electric equipment products work, otherwise cannot turn-on power.Thus realize the protection to operator when power-off is sent a telegram in reply again, prevent unexpected generation.Using electromagnetic induction circuit, combine from even structurally and mechanically structure, have protection reliable, stable, delicate structure, cost of manufacture is cheap, is widely used in the electric tools such as angle grinding machine, buffing machine, wax-polishing machine.
Owing to using such scheme; the press button of this kind of band power-off restarting realization protection has the following advantages and effect: (1) has big electric current machinery break-make and uses function; in the case of endurance life is long, then power-off is sent a telegram in reply again, effectively realize the prompting to operator and defencive function.(2) expanded function, is i.e. using dual alloy material on even circuit KM1 movable contact spring, can realize current overload protection protective function.(3) protection reliability height, compact conformation, cheap, practical, application is extensive.
