Abstract

The utility model relates to the electronic field, particularly an electronic controlling timer socket. The purpose of the utility model is to provide a socket which can control the time accurately with a large time control range, and protect the electric apparatus effectively with a higher efficiency. The utility model mainly comprises a setting control circuit, a control circuit, a display circuit and socket hole circuit. The outer side of a shell is also provided with a time setting button, a time on-off button and a time on-off converting button. All the buttons are connected by a circuit. The electronic display amplifies the signal through D4, and the timer drives a relay through the rectification and the filtration of C3.

Description

Electronic controlling timer socket

The utility model relates to electronic applications, particularly relates to regularly socket of a kind of Electronic Control.

Present employed socket be multiple shape receptacle combinations together, wherein have annexes such as switch, indicator light, voltmeter, only play general power supply connection effect, if the long-term connection circuit of socket, itself also consumes certain electric energy, under unserviced situation, after household electrical appliance need use and finish using, can not will produce serious consequence in time with dump.

The purpose of this utility model provides a kind of socket of Electronic Control timing switch, and the accurately control time, and time range is wide, can effectively protect electrical appliance again, raises the efficiency.

The purpose of this utility model is finished by following scheme: the Electronic Control Timing switch socket comprises: set control circuit, control circuit, display circuit, socket aperture circuit, and be installed in the Socket casing, outside housing, also be provided with timing setting button, timing pass startup button, timing switch change-over switch, all buttons connect by circuit, electronics shows by D4 exports the signal amplification, regularly drives relay by the C3 rectifying and wave-filtering.

The utility model has overcome the single defective of existing function of socket by such scheme; can protect electrical appliance electrical energy saving again simultaneously; not only can be communicated with power supply but also can be regularly from a minute to tens hours for a long time by change over switch, control precision error per minute was less than 0.01 second.

In conjunction with the embodiments the utility model is described in detail at the reference accompanying drawing down:

Fig. 1 is an installation drawing of the present utility model.

Fig. 2 is Electronic Control timing circuit figure of the present utility model.

Among the figure: (1) socket part; (2) regularly show; (3) timing switch change-over switch; (4) timing setting button; (5) timing and common socket change over switch; (6) indicator light; (7) fuse; (8) three terminal regulator; (9) high speed switch tube.

Embodiment: with reference to Fig. 1, outer being provided with of Socket casing (1) regularly shows (2), in order to show the setting of time, simultaneously can show the morning and the time in the afternoon, in addition, also be provided with timing switch switching button (3), regularly with common change-over switches (5) may command long-time and short time to the use of socket.

With reference to Fig. 2, when the digital and electronic table is in hour when transferring than state, the morning of demonstration, the A in afternoon, P printed words are arranged, the voltage output when showing A, P is different, the running that the voltage difference when therefore changing with it is come control relay.Electronic watch has AC signal output when showing A, be added on the high speed switch integrated circuit end after field effect transistor is amplified signal by D4, C3 rectifying and wave-filtering, drives the relay adhesive and reaches regularly purpose.The effect of C4 is to prevent relay contact shake, and D5 plays protection relay, the very little deficiency of output voltage when electronic watch shows P so that the relay adhesive regularly stop.Power supply by alternating current 220V after the transformer step-down by full-bridge rectification, C1 filtering prevents timing circuit because spread of voltage produces misoperation after use for timing circuit after the three-terminal regulator block voltage stabilizing.

Claims

1, a kind of Electronic Control Timing switch socket, it comprises sets control circuit, control circuit, display circuit, socket aperture circuit, it is characterized in that: setting control circuit, control circuit, display circuit, socket aperture circuit are installed in the Socket casing.

2, Electronic Control Timing switch socket according to claim 1 is characterized in that: be provided with regularly design, regularly start or stop, timing switch switching button outside Socket casing.
