Abstract

The utility model relates to a timing on-off device for a power supply, which can provides a timing switch function to electric appliances without timing switch. In an insulating casing, a power lead <U>, a timing switch <A>, a timing on/off functional converter (B. can adopts a bigeminaland bidirectional switch) and a multi-purpose socket <C> are electrically connected in series and in turn. Thus, an independent device with four fundamental modes of timing on, timing off, on and off is formed. While the utility model is used, the power supply <U> is switched on first; then, the timing on/off function and the time are set, and the electric appliance plugged with the multiple used socket.

Description

Timing switch socket

The utility model relates to a kind of power supply time switching device.

Possessing that prior art is produced regularly opened or/and regularly close the electrical equipment of function, all be that regular switching device is directly installed on the electrical equipment, series connection with it, must dispose on one to one ground, and resemble difficult installation regular switching devices such as radio-cassette player, combination audio, ceiling fan, electric furnace, water pump, just be difficult to possess and regularly open, thereby reduced the performance easy to use of many electrical equipment or/and function is closed in timing.

The purpose of this utility model provides a kind of Timing switch socket, and it is separated timing switch controlled function part from traditional electrical equipment, and connects with multipurpose socket, becomes a power supply Timing switch socket device independently.As long as having or not the electrical equipment of control switch to be serially connected on this device, just can realize that the timing of this electrical equipment is opened or regularly closed with power supply.

The purpose of this utility model is achieved in that power supply lead wire, regular switching device, regularly opens/regularly close mode shift key and multipurpose socket is electrically connected in proper order, make electric current successively by regular switching device, regularly open/regularly closing mode shift key transports to socket.Utilize regular switching device regularly to connect the power supply that (perhaps cutting off) transfers to socket, control the electrical work (perhaps stopping) that accesses power supply from multipurpose socket.

Owing to the employing such scheme, just can make still not possess regularly to open and realize that timing is opened or/and timing is opened or/and regularly close the electrical equipment of function, and simple to operation.If adopt smart electronics regular switching device (existing product), then just can join plugging that the timing of putting is repeatedly opened, the timing pass time, and realize the real-time automatic switchover of these two kinds of working methods.In addition, can also further expand its service function by installing devices such as infrared remote control, function display screen, voltage stabilizing, overload protection, prompting alarm bell additional.

Below in conjunction with basic circuit principle accompanying drawing and Timing switch socket embodiment, to timing of the present utility model open, regularly close, open and close four kinds of fundamental modes and using method be described further (present embodiment is to adopt the mechanical timer derailing switch, to adopt bigeminy bidirectional switch＜realizations regularly to open/regularly close the working mode selection function〉to constitute timing switch controlled function part and the Timing switch socket of taking the single line timing control circuit to make be example.If use the smart electronics timer instead or/and adopt two-wire＜or triple line during timing control circuit, circuit diagram is understood some change, but basic functional principle is constant).

Among the figure: A. regular switching device B. bigeminy bidirectional switch C. multipurpose socket U. power supply lead wire L ₁. insert power supply indicator L ₂. regularly close indicator light L ₃. regularly open indicator light L ₄. the socket power indicator light

Regularly open.Time (regular switching device＜A this moment〉interior movable contact spring connect a-b) is set earlier, puts bigeminy bidirectional switch＜B more promptly connect f-d in " regularly opening ", a-b-i-g also connects simultaneously, and indication＜L is opened in timing ₃Lamp is bright, regularly finishes moment, regular switching device＜A〉to c, ab disconnects L to interior movable contact spring by b place bullet ₃Lamp goes out, and a-e-f-d connects, socket power indication＜L ₄Lamp is bright, is plugged on socket＜C on closed electrical equipment obtain power supply and start working.

Regularly close.Time (regular switching device＜A〉interior movable contact spring connect a-b) is set earlier, puts bigeminy bidirectional switch＜B more promptly connect e-d in " regularly closing ", also connect a-b-h-g and a-b-e-d simultaneously, regularly close indication＜L ₂, socket power indication＜L ₄Lamp is bright.Regularly finish moment, ab disconnects, L ₂, L ₄Lamp extinguishes simultaneously, is plugged on socket＜C〉on closed electrical equipment quit work because of outage.

Push And Release.Regular switching device＜A〉not work, movable contact spring is connected a-c always, so L ₂, L ₃Lamp does not work.As shown in drawings, put bigeminy bidirectional switch＜B〉when right-hand member, a-c-f-d connects to opening L ₄Lamp is bright; Otherwise for closing L ₄Lamp goes out.

This embodiment only relies on indicator light L when practical application ₁, L ₂, L ₃, L ₄The just working method of Timing switch socket as can be known of light on and off.
