Abstract

The utility model relates to a remote signalling sensing socket used in an alternating current branch. A voltage indicating instrument and an interface component which meets the requirement of different plugs are installed in a beautiful plastic housing. The utility model is characterized in that the utility model has a current-controlled switch, an over-current protecting element, an optical display element, a current sensing element, a triggering controlled rectifying component and a sound emulating component which are welded, thus forming a circuit board. When the circuit load plug is contacted with the interface component of the device, because of the effect of the sensing element, the sound emulating component gets triggering controlled rectifying voltage and sends out the sound, such as famous songs, famous music or languages to show that the connecting performance of a load circuit and the device is good. When the load is in an intermittent operation (such as a refrigerator), the device can send out sound when the utility model works every time.

Description

Remote signalling sensing socket

The utility model relates to the plug assembly that a kind of power supply is connected with load circuit, especially has the remote electrical equipment Dynamic Signal of sensing, and the remote signalling sensing socket of multiple function.

At present, known socket has only single grafting effect mostly, shows and overcurrent protection function that dynamic for the following loaded work piece of socket, itself can not show intuitively though there are some products to increase voltage.The popularization and application of the household electrical appliance of current a multitude of names and the business automation equipment of various functions has brought a lot of convenience for people's life, work, study.But some socket reasons are also arranged, cause the electrical equipment cisco unity malfunction, fault having occurred can not in time get rid of.So existing outlets level can not satisfy people's life requirement.

The purpose of this utility model provides a kind of remote signalling sensing socket, not only plays the grafting effect of power supply and load circuit, and has supply voltage demonstration, load circuit overcurrent protection and load dynamic sensitive Presentation Function.Particularly when load plug inserts this device socket, this device can send the imitative sound of the Nature such as masterpiece in music, name song or voice automatically and ring, and collection uses and appreciates and be one.

Two binding posts that the purpose of this utility model is achieved in that voltmeter V respectively with (3) .(4 of this device K switch) pin is connected; the end of overflow protecting element BX is connected with K switch (3) pin; the other end is connected with jack interface spare An end; the end of load-transducing element CT is connected with controlled rectification diode SCR negative electrode with K switch (4) pin; the other end is connected with jack interface spare Bn with the controlled rectification diode triggered utmost point; the anode of controlled rectification diode is connected the other end of resistance R 2 and the negative pole of capacitor C with an end of resistance R 1 and an end of resistance R 2.One end of resistance R 3 is connected with the negative pole of imitative sound ic chip, (2) pin of transformer B, and positive pole, the other end of resistance R 3, the positive pole of capacitor C, indicator light ZD one end of imitative piece ic chip are connected resistance R with mouthpiece An ₁The other end be connected with the other end of indicator light ZD, (1) pin sound of transformer B is connected with the output stage of imitative sound ic chip and one of them terminals of horn in H TD, the other end of horn in H TD and transformer B(3) pin is connected, and is to improve volume, and horn in H TD is added with sound-aid cavity.

The utility model utilizes the negative resistance of semiconductor element and nonlinear physics performance to design.Select for use double diode as the load-transducing element, because its volume is little, and is easy for installation, sensing trigger impulse voltage and the influence that not changed by bearing power, can impel the silicon controlled angle of flow to keep certain scope, guarantee that imitative sound integrated package can obtain relative stable DC voltage.

Electricity work principle of the present utility model is: the interface that inserts this device when load plug, and switch between the loop inserted connection, when load current passes through sensing element CT, there is the sine pulse voltage of IV at its two ends, trigger unidirectional controllable silicon S CR conducting with this sensing pulse signal, alternating current is behind silicon controlled rectifier, and commutating voltage one tunnel is through R ₁Luminous to indicator light, another road is by the pressure limiting resistance R ₂The filtering of step-down, capacitor C and load resistance R ₃Effect, imitative sound assembly (comprising integrated package, transformer and loudspeaker) obtains corresponding direct voltage and sends the sound.10-30 is after second in pronunciation, and imitative sound assembly stops pronunciation automatically, and the indicator light continuation is luminous.When load plug breaks away from interface 1-2 second, or load is when intermittently connecting once more, and this device still can repeat-of-pronunciation.Be out of order when causing electric current excessive as load wire short circuit or electrical equipment, protection component BX fuses at once, thereby has protected sensing element and the following whole load circuit of socket.When finding that indicator light does not work, do not have imitative sound yet and ring, promptly be considered as load and power supply and do not form the loop.

Imitative sound of the present utility model rings assembly, does not connect to melt to send out pin and can connect pronunciation synchronously with load, and critical component is a resistance R ₃, resistance R here ₃Effect one be that the imitative sound of protection integrated package is not impacted by peak voltage, the 2nd, form discharge circuit with capacitor C.When plug breaks away from socket, the sensing triggering signal disappears, and controllable silicon is when obstructed, and capacitor C is still charged, and two of imitative certainly sound ic chip are positive and negative extremely also charged, even load is connected once more, imitative sound assembly can not pronounce yet.Have only this following period of time of connecting again when the plug disengaging, capacitor C is to the R3 discharge off, and imitative sound pronunciation could be inserted interface formation pull(ing) effect with plug.

Owing to adopt such scheme, under the prerequisite that does not influence the electrical work performance, changed the single grafting effect of socket, particularly help improving the load Dynamic Recognition ability of people to maybe feeling beyond the visual line of sight, and accident analysis, elimination ability.
