Abstract

The utility model discloses a clock controlled multifunctional socket which belongs to the electronic technical field and is a novel household appliance orderly connected with a digital display electronic clock, a relay, a power regulator, a safety fuse and a combined socket to form integration. A clock integrating path is used for timing, also sends out control signal according to predetermined switching on and off process to drive the relay and control the switching on and off of the combined socket, and the number of times of switching on and off can reach 1-2. A double direction silicon controlled pressure regulating route adjusts output power; the combined socket is suitable for plugs in various shapes and realizes timed switching on and off process controlling and power adjusting for various household appliances.

Description

Clock controlled multifunctional socket

The utility model belongs to electronic technology field.

From existing document, the digital clock of simple function, time switch or power governor are existing varied, but these are all at certain concrete application target and design separately, and great majority are applied to the Industry Control aspect, lack versatility.The utility model adopts extensive integrated circuit of clock, numeral is shown that electronic clock, relay, power governor are incorporated in band and protect in the plate connector test silk and form the clock multi-function jack, realized timed sequence control and power adjustments various household electrical appliance.

The purpose of this utility model is to provide household electrical appliance attractive in appearance, practical, economic, multi-functional for family.

Figure one is a clock timer circuit block diagram.Power supply is a direct current of voltage regulation, installs standby power supply additional.The clock IC of band display driver utilizes the power frequency of 50Hz or quartz oscillator as the timing source, except that being used for general timing, also is used for time switch control.Clock IC exports high level by default conduction time, makes the triode conducting and the relay 1 that drives two pairs of contacts is realized opening automatically of socket power, in case arrive power off time, then the high level of clock IC output is converted to low level and cuts off the electricity supply.Select suitable clock IC, 1～2 time power on/off control program can be arranged every day.K switch is manually and automaticallyes switch among the figure, and 2 is electromotion pilot lamp, and 3 is the auto-programming functional indicator light, and 4 is digital display board, can select light emitting diode or liquid crystal digital plate for use.

Figure two is the power governor wiring diagram, among the figure, 5 is two pairs of contact switchs of relay, and 6 is two-way silicon diode, control the bidirectional triode thyristor conduction angle with potentiometer and capacitor, change voltage, to reach the purpose of regulating power, 7 for there being a plurality of jack plate connectors, wherein two stamen sockets do not have the power adjustments function, be used for can not pressure regulation electrical equipment, parallel three stamen sockets both had been suitable for three stamen plugs, were fit to three stamen plugs again.

Figure three is a clock multi-function jack panel arrangement sketch plan.Among the figure 8 when being the school, school branch, preset switches time-program(me) button, 9 is the power adjustments knob, 10 is fuse.

Claims

1, a kind of clock multi-function jack, showing by numeral that electronic clock, relay, pressure regulator, fuse, plate connector box connect in turn forms, the break-make that it is characterized in that socket power is controlled by digital electronic clock, clock IC exports high level signal in default conduction time, through amplifying the rear drive relay, the conducting socket power, in non-conduction time, clock IC output low level signal, relay discharges, cut off socket power, the silicon-controlled voltage regulation device scalable power that between relay and socket, installs additional.

2, by 1 described digital electronic clock, base when clock IC does with power frequency or crystal oscillator frequency, display panel used light emitting diode or liquid crystal digital plate; The power supply rectification DC power supply installs reserve battery additional.

3, all use push-botton operation by the time adjustment of 1 described clock multi-function jack and the switching programme of socket power, corresponding time showing is arranged, the power adjustments knob-operated on the display board simultaneously.
