Abstract

The utility model relates to a clock controlled power socket which is composed of an electronic clock, a clock controlled timing switch, a power socket plug, a power indicator, etc. The clock controlled power socket primarily outputs the driving control signal from the K-shaped drawing electrode in the electronic clock chip circuit and the COM public electrode lead. After the rectification, the voltage reduction, and the wave filtering in the clock controlled circuit, the driving control signal acts as the clock controlled signal source of the clock controlled circuit to realize that the power socket is automatically controlled in a timing way. The clock controlled power socket integrates the electronic clock, the clock controlled timing switch, the power indicator, the socket and the connecting plug into a whole body. The utility model has the advantages of simple and compact structure, high accuracy, convenient operation, low cost, easy fabrication, large timing control range, and large direct controlled power. The utility model is suitable for all household appliances, and electronic instruments and devices as a timing automatic control switch.

Description

Clock-controlled power socket

The utility model is a kind of current collection period of the day from 11 p.m. to 1 a.m clock, the clock timing switch, and the power supply indication, socket, connecting plug is in the clock supply socket of one.Existing various timed unit can be divided into two big classes substantially: a class is made up of complicated integrated circuit and discrete component, though performance is more comprehensive, because the circuit complexity, therefore the cost height, in present stage, is difficult to generally promote the use of to general family; Another kind of is to utilize existing analog timepiece, joins the part machine components and electronic component is formed through some repacking or increase, lower than preceding class from cost, but its mechanical structure and circuit are still complicated, and timing accuracy is not high, uses not enough flexibly, convenient.

The purpose of this utility model is to overcome above-mentioned deficiency, provide on a kind of the K stroke electrode and COM public electrode in the chip circuit of clock, lead-in wire connects clock control circuit, by rectification, step-down, the filtering of clock control circuit, output clocked signal and realize the clock supply socket that timing automatic control is opened and closed.

Be described further below in conjunction with accompanying drawing and enforcement:

Fig. 1 is a surface structure schematic diagram of the present utility model, (1) mains switch among the figure, (2) clock control circuit, (3) electronic clock, the indication of (4) power supply, (5) socket group, (6) connecting plug, (7) clock regulatory function switching button, (8) clock collating time button;

Fig. 2 is a circuit theory schematic diagram of the present utility model, mains switch among the figure (1) is the normally opened contact J1-2 and the normally-closed contact J1-3 of relay, perhaps use bidirectional triode thyristor element and change over switch K1, clock control circuit (2) is by silicon rectifier diode D1 and D2, filtering capacitor C1 and C2, dropping resistor R, miniature high power relay J, formations such as fet power pipe V-MOS, electronic clock (3) is the chip circuit that adopts 3 half digital liquid crystal display 24 stroke outputs, power supply indication (4) is to utilize the capacitor C3 of fluorescent lamp starter and neon lamp ND reconfiguration to form, socket group (5) is by the garden, flat pin two, three sockets of four kinds of forms of three plugs rearrange, and connecting plug (6) (contains fire by one the three soft electric wire of core, zero, ground wire) and flat pin three plugs form; Except that connecting plug (6), other (1), (2), (3), (4), (5) part are assembled in the Socket casing that an insulating material makes;

Fig. 3, the 4th, two kinds of switching circuit schematic diagrames in addition of mains switch (1).

According to shown in Figure 2: the silicon rectifier diode D1 of clock control circuit (2), dropping resistor R and filtering capacitor C1, be used separately as 220 volts of ac voltage rectifiers, step-down and low-voltage filter, the two ends operating voltage that makes miniature high power relay J is 12 volts of direct currents, silicon rectifier diode D2 and filtering capacitor C2, use 32 hertz of square-wave signals to carry out rectification and filtering respectively to clock circuit output, when 32 hertz of square wave clocked signal output, drain electrode at field effect power tube V-MOS, the source electrode conducting, make the relay J energising and the normally opened contact J1-2 and the release normally-closed contact J1-3 of adhesive mains switch (1), its time control range turn in 9 hours, in 3 hours, close electrical equipment certainly, as shown in Figure 3, normally opened contact J1-2 by relay, the connection of normally-closed contact J1-3 and usefulness, or as shown in Figure 4, normally opened contact J1-2 by relay, the connection of normally-closed contact J1-3 and change over switch K1, the time control range was opened in 9 hours certainly, close electrical equipment, electronic clock (3) is with the chip circuit of 3 half digital liquid crystal display 24 stroke outputs, on the K stroke electrode and COM public electrode from chip circuit, 32 hertz of square wave driving signals of lead-in wire output K stroke, clocked signal source as clock control circuit, regulate the function switching button (7) and the time adjustment button (8) of clock, change the time of its demonstration, just can arbitrarily the automatic energising work and the outage of control apparatus quit work in 9 hours scopes.Electronic clock adopts existing finished product, itself can make clock separately uses, cooperate the socket time spent, add on welding two go between K and COM electrodes, be placed in the socket, just become the clock supply socket, if make common socket usefulness, as long as clock is regulated October, November or the December that is presented at moon demonstration; Power supply indication (4) is to utilize capacitor C3 and neon lamp ND reconfiguration in the fluorescent lamp starter to form, and represents "on" position when neon lamp is bright, represents off-position when putting out; Socket group (5) is by rearranging for three sockets that are fit to garden, four kinds of form plugs of flat pin two, three plugs; Connecting plug (6) is made up of one the three soft electric wire of core (containing fire, zero, ground wire) and flat pin three plugs.

For example, after clock was passed by X hour, as the timing automatic energized, then regulate the function switching button (7) and the time adjustment button (8) of clock, make clock show that time y(established then y=10:00-X=3 hour 40 minutes X=6 hour 20 minutes), like this, after clock was walked X hour, the clock supply socket just can be connected the working power of electrical equipment automatically; And after clock passed by X ' hour, automatically shut down the power supply of electrical equipment, then the adjustment clock shows that time y ' (establishes X '=1 hours 30 minutes, then y '=13:00-X '=11 are hours 30 minutes), like this, after clock was walked X ' hour, the clock supply socket just can automatically shut down the working power of electrical equipment.

The supply socket of this clock be applicable to the timing automatic control switch of all household electrical appliance and electronic instrument and equipment, and timing range is big, and precision is accurate, and directly power controlling is big, simple in structure, and cost is low, easily produces.
