Description
Technical field
The present invention relates to a kind of mechanical switch, and in particular to a kind of passive and wireless micro-machinery switch.
Background technology
The place for needing to be controlled the break-make of signal will use switch.The switch used in electronic circuit mainly has
Two major class of mechanical switch and semiconductor switch；The advantages of mechanical switch is that its OFF state signals leakiness is very small, and shortcoming is one
As volume it is larger, switch time delay is longer, there is service life number；The advantages of semiconductor switch is that small, switching voltage and switch prolong
When it is small, the drawback is that standoff voltage leakage it is larger.
Passive and wireless switch refers to switch on-off by passive and wirelessly realize.It is wireless to refer to control section and open
Close part and do not have wired connection, it is passive to refer to that switch sections do not have power supply or battery.And existing wireless switching, generally using radio frequency
Transmitting-receiving mode is controlled switch, and battery is needed in switch element and is powered to transmission circuit.Because containing battery, therefore this
The service life of kind wireless switching is limited.
Micro-machinery switch is one kind of mechanical switch, it uses micro Process mode to make.Therefore, it is remained mechanically
The characteristics of OFF state signals leakiness of switch is very small, and have small advantage, available for the logical of direct current, low frequency or radiofrequency signal
Disconnected control.Since the execution voltage of micro-machinery switch is higher, generally higher than 30V, therefore existing control micro-machinery switch is logical
Disconnected mode is all wired.
The content of the invention
Goal of the invention：To overcome above-mentioned the deficiencies in the prior art, the present invention provides a kind of passive and wireless micro-machinery switch.It is logical
Cross using wirelessly come controlling switch, it is easy for installation, the trouble of wiring is saved, it is more intelligent, be free of in Simultaneous Switching
Power supply or battery, add service life.
Technical solution：A kind of passive and wireless micro-machinery switch, including receiving coil, micro-machinery switch, rectification circuit, signal
Input terminal and signal output part；Wherein, micro-machinery switch includes movable electrode, contact, bias electrode and output electrode；Rectified current
Road includes resistance, capacitance and rectifier diode；
Rectifier diode series capacitance, resistor coupled in parallel capacitance, the output terminal of resistance and the output terminal of rectifier diode are distinguished
As the output terminal of rectification circuit, the input of the input terminal of rectifier diode and the output terminal of capacitance respectively as rectification circuit
End；The input terminal of the input terminal of movable electrode and the input terminal of bias electrode respectively as micro-machinery switch.
The both ends of receiving coil connect the input terminal of rectifier diode and the output terminal of capacitance respectively, and the input terminal of resistance connects
Connect the input terminal of movable electrode, the input terminal of the output terminal connection bias electrode of resistance, the input terminal connection signal of movable electrode
Input terminal, the output terminal connection signal output part of output electrode.
The break-make of micro-machinery switch can be controlled by the way of passive and wireless.
Beneficial effect：It is easy for installation by using wirelessly carrying out controlling switch, save the trouble of wiring, mobility
By force, it is more intelligent without the limitation in space, without using power supply or battery in Simultaneous Switching, use cost is saved, adding makes
Use the service life.
Brief description of the drawings
Fig. 1 is the circuit diagram of the present invention；
Fig. 2 is the principle of the present invention block diagram.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of passive and wireless micro-machinery switch, including receiving coil 1, micro-machinery switch 2, rectification circuit 3,
Signal input part 4 and signal output part 5；Wherein, micro-machinery switch 2 includes movable electrode 201, contact 202, bias electrode 203
With output electrode 204；Rectification circuit 3 includes resistance 301, capacitance 302 and rectifier diode 303.
In rectification circuit 3,303 series capacitance 302 of rectifier diode, 301 shunt capacitance 302 of resistance, resistance 301 it is defeated
The output terminal of outlet and rectifier diode 303 respectively as rectification circuit 3 output terminal, the input terminal of rectifier diode 303 with
Input terminal of the output terminal of capacitance 302 respectively as rectification circuit 3.In micro-machinery switch 2, the input terminal of movable electrode 201
Input terminal with the input terminal of bias electrode 203 respectively as micro-machinery switch 2.
Using the near-field coupling of inductance, AC controling signal is coupled on receiving coil 1, the both ends point of receiving coil 1
Not Lian Jie rectification circuit 3 input terminal, the AC signal that rectification circuit 3 will be coupled on receiving coil 1 becomes after over commutation
Direct current signal sends micro-machinery switch 2 to, and the output terminal of rectification circuit 3 connects input terminal and the biasing of movable electrode 201 respectively
The input terminal of electrode 203, the input terminal connection signal input part 4 of movable electrode 201, the output terminal connection letter of output electrode 204
