Description

The computer power supply socket

The utility model relates to supply socket, is specifically related to the supply socket that computing machine is used.

Present widely used supply socket generally is to be made by plastic casing and bag electrical contact within it, and plastic casing has a plurality of jacks, and the plug of electrical appliance inserts above-mentioned jack both can contact electrical contact, thus energized.The computer power supply socket is identical with above-mentioned common power socket principle of work, the different jacks that only is socket be arranged to and the suitable jacks of external device attaching plug such as main frame attaching plug, display power supply plug, printer power supply plug.This computer power supply socket in use, external devices such as main frame, display are independent energized respectively, during start, must open host power switch, display power supply switch and other external device power switch respectively; During shutdown, essential Shutdown Hosts power switch, display power supply switch and other external device power switch respectively.The computing machine great majority adopt the ATX cabinet at present, the power switch of when shutting down computer, shutting down computer automatically, and other peripheral hardware electrical appliance such as display is manual-lock one by one.We know, after computer power supply is closed automatically, and the indicator screen deepening, the operator often neglects and closes the display power supply switch, and easy like this other external device such as display that causes damages.

The purpose of this utility model is to provide a kind of after computer power supply is closed automatically to the public, the supply socket that display can be closed thereupon automatically.

The utility model computer power supply socket, comprise a baseplug, this baseplug is electrically connected by control socket with at least one by a control circuit, described control circuit is made up of electricity consumption perceptron, current rectifying and wave filtering circuit, trigger circuit and electronic switch, described electricity consumption perceptron is connected in the above-mentioned baseplug power circuit, and be connected with above-mentioned current rectifying and wave filtering circuit, the other end of current rectifying and wave filtering circuit is connected with described trigger circuit, the other end of trigger circuit is connected with described electronic switch, and this electronic switch is connected in the described controlled socket power circuit simultaneously.Described electricity consumption perceptron can be D.C mutual-inductor or Hall element.Described electronic switch can be bidirectional triode thyristor or relay.Described trigger circuit can be photoelectric coupled circuit or transistor switching circuit.

The utility model computer power supply socket is formed by baseplug, control circuit with by control socket, the attaching plug of main frame is inserted in the baseplug, the display power supply plug is inserted in by in the control socket, when the main frame power connection, the electricity consumption perceptron obtains an AC signal, through after the AC mutual induction, at alternating voltage of secondary output, behind rectifying and wave-filtering, this level makes trigger circuit export a high level, this just makes that electronic switch is in open mode, and by the control socket energized, display can start; When the main frame power supply is closed automatically, the level that the electricity consumption perceptron obtains becomes low level, like this, the output of current rectifying and wave filtering circuit becomes low level, and trigger circuit do not have can be for the voltage signal that triggers, therefore, do not export the power level that triggers electronic switch, so just make that electronic switch is in closed condition, by the control socket deenergization, display is closed automatically.Like this, display can overcome operator's carelessness and close the generation of display power supply switch with main frame energized or deenergization, avoids display to be damaged.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model principle of work block diagram;

Fig. 2 is the circuit theory diagrams of the utility model one embodiment.

As shown in Figure 1, the utility model computer power supply socket, comprise a baseplug, this baseplug is electrically connected by control socket with one by a control circuit, above-mentioned control circuit is made up of electricity consumption perceptron, current rectifying and wave filtering circuit, trigger circuit and electronic switch, the electricity consumption perceptron is connected in the baseplug power circuit, and be connected with current rectifying and wave filtering circuit, the other end of current rectifying and wave filtering circuit is connected with trigger circuit, the other end of trigger circuit is connected with electronic switch, and this electronic switch is connected in the controlled socket power circuit simultaneously.

As shown in Figure 2, a kind of embodiment of the utility model is: baseplug P2 is connected with D.C mutual-inductor TF, after the electric current that D.C mutual-inductor TF produces passes through diode D1 and capacitor C rectifying and wave-filtering, enter photoelectric coupled circuit OPTOTRIAC, this photoelectric coupled circuit itself is trigger circuit, it passes to controllable silicon TRIAC with signal, and controllable silicon TRIAC connects by control socket P1, but energized or deenergization.In addition; resistance R 1 in the circuit plays the effect of protection and restriction controllable silicon gate pole Control current and protection photoelectric coupled circuit OPTOTRIAC; resistance R 2 and capacitor C 3 have constituted the surge current when the Ru Erfu circuit is used for suppressing the controllable silicon break-make together; play the effect of protection controllable silicon TRIAC, variable resistor R3 plays the effect of regulating the electric current power.
