Description

Modular jack

Technical field

The utility model belongs to the electric equipment products manufacturing, and particularly electromagnetic relay and modular jack are used.

Background technology

In the student dormitory of electricity failure at night, a part of student is not related to electrical appliances such as outage lamp, electric blanket at present, and computer is in holding state, waits when having a power failure and closes automatically.These electrical appliances delay work under must not operating position and waste electric energy when restoring electricity.School wished can only use in the apartment and provided electric fan for oneself night in summer, but can not stop other electrical equipment to use.

The utility model content

The utility model purpose is in the system that stops power supply night, and electrical appliance nobody's that the back that restores electricity is connected with electrical network operational order is not worked; For night in summer student dormitory can only use sleep wind function electric fan to provide convenience and guarantee.

This practical new construction is a modular jack, by by control socket X ₁, X ₂, electric fan private jack X ₀, control relay coil J ₁And relay contact J _1-K, K switch ₁, voltage-stabiliser tube D ₁, resistance R ₁, decompression capacitor C ₁, storage capacitor C ₂, rectifier (1), oscillator (2), photoelectrical coupler (3), noncontacting switch (4) form, its control section is characterised in that: decompression capacitor C ₁, rectifier (1), control relay coil J ₁, K switch ₁, voltage-stabiliser tube D ₁Series connection; Control relay coil J ₁, K switch ₁, voltage-stabiliser tube D ₁After the series connection again with storage capacitor C ₂In parallel; Noncontacting switch (4) output and electric fan private jack X ₀Connect.This structure has guaranteed that the electrical appliance of working when electric power system has a power failure can not work on, and only obtains could being activated again after the manual operation instruction at controlled electrical appliance when restoring electricity.

School better has a rest in order to make the student night in summer, and the controller that only allows the work of power batch (-type) varying duty is installed in the student dormitory electric power system; When night in summer, the student slept, can only use intermittently used load (electric fan of output sleep wind) in the controlled electric power system.Can work in the controlled electric power system at night in summer for the wind function electric fan of not sleeping, one of them socket of the modular jack that uses in the student dormitory is connected with the output of noncontacting switch.

Fig. 1 the utlity model has electric fan sleep air generator modular jack structural representation.

Fig. 2 is the utility model simple combination formula socket schematic diagram.

Embodiment

Embodiment 1, the utlity model has electric fan sleep air generator modular jack.Be to form to have electric fan sleep air generator modular jack structural representation as shown in Figure 1, by by control socket X ₁, X ₂, electric fan private jack X ₀, control relay coil J ₁And relay contact J _1-K, K switch ₁, voltage-stabiliser tube D ₁, resistance R ₁, decompression capacitor C ₁, storage capacitor C ₂, rectifier (1), oscillator (2), photoelectrical coupler (3), noncontacting switch (4) form.Decompression capacitor C ₁, rectifier (1), relay coil J ₁, K switch ₁(K switch ₁With resistance R ₁Parallel connection), voltage-stabiliser tube D ₁Series connection; Relay coil J ₁, K switch ₁, voltage-stabiliser tube D ₁After the series connection again with storage capacitor C ₂In parallel.Because rectifier (1), voltage-stabiliser tube D ₁Voltage drop is constant, storage capacitor C ₂Two ends do not have voltage stabilizing element and work as K switch ₁When on off operating mode changes, relay coil J ₁Both end voltage variable quantity and storage capacitor C ₂The both end voltage variable quantity equates.Modular jack power switch K ₂During disconnection, storage capacitor C ₂When both end voltage reaches stable state greater than relay J ₁Pick-up voltage and voltage-stabiliser tube D ₁Both end voltage sum, at this moment Closing Switch K ₁Relay J ₁Adhesive is by control socket X ₁, X ₂The load that connects can be worked; K switch ₁Closed back storage capacitor C ₂Both end voltage descends, relay coil J ₁Both end voltage is reduced between the pick-up voltage and release voltage of relay, and relay is kept adhesive.Modular jack power switch K ₁Resistance R when closed ₁By short circuit, storage capacitor C ₂The two ends steady state voltage is less than relay pick-up voltage and voltage-stabiliser tube D ₁The both end voltage sum, relay J ₁Not adhesive.Has only K switch ₁Disconnect back storage capacitor C ₂Two ends steady state voltage increase is Closing Switch K again ₁, just can make relay J ₁Adhesive.So just can make and be inserted in by control socket X ₁, X ₂On do not close and load on when restoring electricity after the power failure, do not have artificial console switch K ₁The state of can not resuming work automatically.

The student dormitory student sleeps school when only allowing to provide electric fan for oneself with sleep wind at night in summer, the electric power system 5 seconds modular jack K switch of powering again that have a power failure ₁Be in any state by control socket X ₁, X ₂All can not power; Voltage-stabiliser tube D ₁The square wave that both end voltage makes oscillator (2) work produce EDM Generator of Adjustable Duty Ratio drives noncontacting switch (4) work by photoelectrical coupler (3).Because noncontacting switch (4) output and electrical network, electric fan private jack X ₀Connect, be inserted in electric fan private jack X ₀Electric fan can produce sleep wind.

Embodiment 2, the utility model simple combination formula socket.Be to form simple combination formula socket schematic diagram as shown in Figure 2, by by control socket X ₁, X ₂, electric fan private jack X ₀, control relay coil J ₁And relay contact J _1-K, K switch ₁, resistance R ₁, decompression capacitor C ₁, storage capacitor C ₂, rectifier (1) forms.Relay coil J ₁, K switch ₁Series connection and storage capacitor C ₂After the parallel connection again with decompression capacitor C ₁, rectifier (1) series connection; K switch ₁Storage capacitor C during disconnection ₂The two ends steady state voltage is greater than the relay pick-up voltage; K switch ₁Storage capacitor C when closed ₂During the both end voltage stable state between relay pick-up voltage and release voltage, must console switch K when restoring electricity ₁Just can make by control socket X ₁, X ₂Restore electricity.

The student dormitory student sleeps school when only allowing to provide electric fan for oneself with sleep wind at night in summer, the electric power system power failure 5S modular jack K switch that restores electricity again ₁Be in any state by control socket X ₁, X ₂All can not power; Be inserted in electric fan private jack X ₀The electric fan that possesses sleep wind function can work, produce sleep wind.
