Abstract

The utility model relates to a timing power source socket, which is composed of a power source socket, a pointer type timer clock, a trigger switch, etc. for an integral structure; the timing power source socket uses the timer clock as a control kernel, and has the advantages of convenient operation, low cost, etc.

Description

Supply socket that can be regularly

The present invention relates to the electric switch technical field.

In daily life, people often need regularly to start or close the work of certain electrical equipment.Having occurred a kind of now on the market serves as the timing switch of control core with computer single-chip microcomputer or large scale integrated circuit, though this timing switch function is more, has troublesome poeration, shortcomings such as manufacturing cost height.If can make timing switch with the common pocket timing small alarm clock of average family, though function has been lacked, easy to manufacture, with low cost, it is also simple and convenient to operate.

The objective of the invention is to design a kind of serves as control Timing power supply socket core, cheap practicality with pocket small alarm clock.

This supply socket that can regularly connect is formed integral structure by several parts such as supply socket, pointer type timer clock and trigger switches.Supply socket is used for inserting electric current from power supply, and then to the electric power supply of outside; The effect of pointer type timer clock is the demonstration time, sets the quarter-bell time and export triggering signal on time; Trigger switch can be carried out switch motion after receiving the triggering signal that timer clock sends here, the coupled situation between control supply socket and the power supply, thereby the electrical work on the Timing controlling plug seat.

Be described below in conjunction with embodiment.

Fig. 1 is the appearance and modeling figure of present embodiment Timing power supply socket, and wherein 1-a is a front elevation, and 1-b is a back view.

With reference to Fig. 1, the Timing power supply socket is formed integral structure by power line (1), indicator light (2), flip button (3), trigger switch (4), pointer type timer clock (5) and supply socket parts such as (6) in the present embodiment.Wherein trigger switch (4) can be controlled the coupled situation between supply socket (6) and the power line (1), but trigger switch (4) is limited by pointer type timer clock (5) again simultaneously, is trigger action when.Timer clock (5) is provided dry cell for oneself, it can send ring tone after running to the quarter-bell setting-up time, also can produce the triggering signal of telecommunication simultaneously, and this triggering signal is delivered to after the trigger switch (4), the wherein built-in actuating of relay realizes periodically controlling the household electrical appliance in the supply socket (6).Timer clock (5) can come correction time from the knob at the back side and set the quarter-bell time---and this also is the operate time of trigger switch (4) simultaneously.

Signal lamp (2) is used to indicate the current on off operating mode of supply socket (6).Flip button (3) can allow the state of a control of trigger switch (4) overturn at any time.

Fig. 2 is the appearance and modeling figure of pointer type timer clock in the present embodiment.Wherein 2-a is positive, and 2-b is a back view.

Pointer type timer clock (5) in the present embodiment is directly selected all very common pocket electronics small alarm clock at present a lot of families for use, it is embedded in the supply socket (6) then.Referring to Fig. 2, model that the small alarm clock of this pointer type also has nothing concrete, its inside is that the oscillating circuit by the fixed cycle encourages stepping motor, promotes gear train and pointer and comes instruction time.The principle and the detailed structure of alarm clock do not dwell on here, and we get final product at ready-made copying mechanically.

A miniature contact-making switch is generally all arranged in this small alarm clock, is its schematic diagram as Fig. 3.When the small alarm clock pointer ran to the moment that quarter-bell sets, the movable contact spring N utmost point of this contact-making switch can fall, and with two electrode short circuits of static contact M1, M2, so the circuit that M1, M2 two electrodes link causes the quarter-bell circuit working, rang when quarter-bell is opened.Here we need process slightly to this contact-making switch, are promptly welding a wires L1, L2 on M2, N the two poles of the earth respectively, and are drawing after an aperture is bored in the alarm clock side, export to trigger switch (4) as line trigger signal.Need only timing one like this and arrive, the contact-making switch closure, trigger switch (4) is also with regard to trigger action, and supply socket (6) is gone up electrical equipment and is just started working.

Fig. 4 is the circuit diagram of trigger switch in the present embodiment (4).

Trigger switch (4) circuit board is hidden in the inside of supply socket (6).

With reference to Fig. 4, the trigger switch circuit is made up of several parts such as voltage stabilizing circuit, relay, trigger switches.

At first need to prove: the relay K is here selected homemade novel memory latching relay ZS-01F for use, is characterized in that it can remember and keep state of a control before the power down.Because special internal structure, the every energising of this relay are once, the switch that it is controlled just overturns once, promptly is connection from blocking jumping, or jumps to blocking from connecting, and it just maintains the power failure back connection or block state.The circuit diagram of relevant memory latching relay ZS-01F and trigger switch (4) has introduction on 2000 the 1st phases " CYBERSPACE ".

Voltage stabilizing circuit is by R ₁, D ₁, C ₁, D ₂Deng composition, civil power is through R ₁Step-down, D ₁After the rectification, by D ₂Voltage stabilizing is about 12V.C ₁It is storage capacitor.When K2 or K3 closure, C ₁Just to the relay K discharge, so the K that this memory latching relay K is controlled ₁Just adhesive, supply socket R _LObtain power supply, with R _LIndicator light LED in parallel is also simultaneously luminous.Work as K ₂Or K ₃After the disconnection, since the memory latching characteristics of relay K, K ₁Still keep closure, supply socket R _LStill can continue external power supply.

Work as K ₂Or K ₃When closed once more, relay K can be moved again, K ₁To overturn to disconnecting.And so forth.

K ₃What overlap is the triggering signal of drawing self-timing alarm clock (5), and contact-making switch one closure when timer clock (5) lining also just is equivalent to K ₃Closure, the trigger switch circuit will overturn once certainly.K ₂That has addressed exactly is placed in flip button (3) on the electric socket panel, and LED is exactly indicator light (2).

Element is selected for use.R ₁: 150K Ω, 1/4W fixed carbon resister; D ₁: 1N4007; R ₂: 150K Ω, 1/4W fixed carbon resister

C ₁: the CD11-16V electrochemical capacitor; D ₂: 12V, 1/4W ordinary silicon voltage stabilizing didoe;

K:ZS-01F remembers latching relay; LED: neon bulb.

Can supply socket regularly have the following advantages:

Employing is made control core with the pocket timer clock of pointer, and easy to manufacture, cost is low, behaviour Do simple and convenient.

Claims

A kind of supply socket that can timing switch is formed integral structure by supply socket, pointer type timer clock and trigger switch etc., it is characterized in that: the Timing power supply socket serves as the control core with the pointer type timer clock.
