Description

Electric conductance sound-imitating switch

The utility model relates to a kind of electrical load device for controlling dynamically, and especially when load was opened, this device can send imitative sound automatically and ring, and in load running, has overcurrent protection, and multi-functional electricity such as dynamic demonstration are led sound-imitating switch.

At present, known load device for controlling dynamically, the lighting switch as commonly used comprises pulling switch and key swich, generally all is the hilted broadsword control type, only the load circuit single conductor is played on-off action.In case circuit breaks down, the electric blind user for considerable part fixes a breakdown and just has no way of doing it.The switches such as temperature adjustment, speed governing, pressure regulation that also have some household electrical appliances except that the advantage with self, owing to having only basic control function, and do not have overcurrent protection and load dynamic display of functional.In real life, often bring some unexpected loss and inconvenience to the people.

The purpose of this utility model; provide a kind of modern design; multifunction electric rational in infrastructure is led sound-imitating switch; it not only plays the dynamic control action of load; and have overcurrent protection and a load dynamic display of functional; particularly work as switch connection, when load brought into operation, this device can send the imitative sound of the Nature such as masterpiece in music, name song or language automatically and ring.To show that load movement is normal.

The purpose of this utility model is achieved in that arbitrary end of overflow protecting element BX is connected with the one electrode of double-pole switch K output; arbitrary end of light display element neon bulb ND4; arbitrary end of load-transducing element CT; the negative electrode of controlled rectification element SCR connects with another electrode of double-pole switch K output; controlled rectification element SCR anode connects with arbitrary end of pressure limiting resistance R 2; the negative pole of the other end of resistance R 2 and filter capacitor C; the negative pole of the arbitrary end of load resistance R3 and imitative sound ic chip connects; the output stage of imitative sound ic chip connects with (1) pin of matching transformer B and arbitrary electrode of horn in H TD; another electrode of horn in H TD connects with matching transformer (3) pin; (2) pin of transformer B; the positive pole of imitative sound ic chip; the other end of load resistance R3; the positive pole of the molten C of filtered electrical; the other end of protection component BX connects resistance R 1 arbitrary end with neon bulb and connects; the other end that connects resistance R 1 connects with the other end of neon bulb, and the control utmost point of controlled rectification element SCR and the other end of load-transducing element connect.For improving volume, horn in H TD is added with sound-aid cavity.

The utility model utilizes semiconductor element load and nonlinear physics performance and designs, select for use bidirectional diode as the load-transducing element, because its volume is little in light weight, easy for installation, after passing through, electric current do not change original waveform, particularly the sensing trigger impulse voltage that is produced in the working range reaches the influence that not changed by bearing power, thereby impels the silicon controlled angle of flow to keep certain scope, guarantees that imitative sound integrated package can obtain relative stable DC voltage.In addition, the voltage drop of this sensing element only is 1V, compares with supply voltage 220V or 380V, can not influence the serviceability of each power consumption equipment.

Whether imitative sound of the present utility model ring the connection generation synchronous reaction with switch, and critical component is a resistance R 3.Here the effect of resistance R 3; the one, the imitative sound of protection integrated package is not impacted by peak voltage, and the 2nd, form discharge circuit with capacitor C, as not establishing resistance R 3; when switching circuit disconnects; the triggering signal of sensing element disappears, and causes controllable silicon to be closed when obstructed, and capacitor C is still charged; owing to connecting the circuit reason; charged between two both positive and negative polarities of imitative sound integrated package, when switch was connected continuously once more, this device can not pronounce yet yet.Have only when switching circuit and connect in--disconnections--connects during this period of time again, capacitor C is to resistance R 3 discharge offs, pronounce for imitative could with the connection generation pull(ing) effect of switch.

Electricity work principle of the present utility model is: work as switch connection, when load current passes through sensing element CT, its two ends produce the sine pulse voltage of 1V, trigger unidirectional controllable silicon S CR conducting with this sensing pulse signal, under the alternating current 220V Power Supplies Condition, the silicon controlled anode just produces the halfwave rectifier voltage of 110V, and through the filtering and the load resistance R3 effect of resistance R 2 step-downs, capacitor C, imitative sound assembly (comprising IC integrated package, transformer and loudspeaker) obtains corresponding direct voltage and sends sound equipment again; Pronounce some second after, imitative sound assembly stops pronunciation automatically, connect after switch cuts out, or load is when intermittently working once more automatically again, this device still can repeat-of-pronunciation.Break down as load wire short circuit or electrical equipment itself, when causing electric current excessive, protection component BX fuses at once, thereby has protected sensing element and the following load circuit of switch.The light display element of this device, switch connection will be luminous.If light shows normally not to be rung and there is imitative sound, illustrate that switch following load and power supply do not form the loop in the use, still not reaction after the replacing load, fault is undoubtedly the BX element, and sensing element or lead and contact have fault.

Owing to adopt such scheme, under the prerequisite that does not influence the electrical work performance, changed the single on-off action of switch, improved the Electrical Safety index, particularly help to improve people to load Dynamic Recognition ability, and the accident analysis elimination ability.
