Abstract
An automatic power cutoff computer socket belongs to daily electrician device field, which comprises a plug, a lead, a shell and a metal sheet, wherein, the shell is provided with an insertion hole with the metal sheet arranged downside of the insertion hole, which is characterized in that an automatic power cutoff device is arranged between the plug and the metal sheet, one end of which is connected with the plug by the lead, while the other end of which is connected with the metal sheet inside of the shell. The utility model with the arrangement of automatic power cutoff device to cut off the main circuit when the computer closes the system, current in the main circuit of computer is reduced and voltage can not reach the action voltage of the automatic power cutoff device without waiting for system close time particularly, therefore improving the close efficiency with a simple structure and convenience.
Description
Technical field
The utility model relates to a kind of Socket for computor of automatic outage, belongs to daily electrical equipment field.
Background technology
Usually the open and close machine of computer needs the process of a wait, particularly when shutdown, after needing computer system to close, could disconnect general supply, but because system closing needs a period of time, a lot of users do not wait system closing just to withdraw from a room, after allowing computer close always for the holding state before starting, after testing, under the holding state of computer (comprising peripheral hardwares such as display and sound equipment or printer) before startup, total about 0.1A of circuit circuital current, the about 0.7A of the electric current during operate as normal.If computer standby every day 12 hours, the electric energy that consume every day is 220v * 0.1A * 12h=0.264 degree.Waste valuable electric energy like this, and will shorten the life-span of computer power part.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, and is easy to use, the Socket for computor that can cut off the power supply automatically after closing computer system.
The technical scheme that its technical problem that solves the utility model adopts is: the Socket for computor of automatic outage, comprise plug, lead, shell and sheet metal, leave jack on the shell, sheet metal is installed in the jack bottom, it is characterized in that between plug and sheet metal, auto-power-off device being set, plug is by an end of lead connection auto-power-off device, and the other end of auto-power-off device connects the sheet metal of enclosure by lead.
Described auto-power-off device comprises joint J1, J2, transformer T1, capacitor C 1, diode D1-D6, button AN1, relay K M1, KM2 and with relay K M1, the normally opened contact K1 that KM2 is associated, K2, normally opened contact K1 is connected on the lead, be in series with capacitor C 1 successively near between the lead of joint J1, diode D6 and relay K M1, normally opened contact K2 is in parallel with button AN1, be connected then between diode D6 and the relay K M1, at primary side near connection transformer T1 on the lead of joint J2, the secondary side of transformer T1 connects the input of the rectifier bridge of being made up of diode D1-D4, diode D5 is in parallel with relay K M2, be connected on then between the output of rectifier bridge, joint J1 is connected with attaching plug, and joint J2 is connected with sheet metal.
Its operation principle is, auto-power-off device is provided with certain operation voltage, when normally using computer, main circuit current is bigger, has reached the operation voltage of auto-power-off device, and main circuit is kept path, after the computer shutdown system, the computer main circuit current reduces, and voltage does not reach the operation voltage of auto-power-off device, and auto-power-off device disconnects main circuit.
Advantage of the present utility model: by auto-power-off device is set, after the computer shutdown system, the computer main circuit current reduces, voltage does not reach the operation voltage of auto-power-off device, auto-power-off device disconnects main circuit, does not need the special waiting system unused time, has improved the pass engine efficiency, and it is simple in structure, easy to use.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is the circuit theory diagrams of auto-power-off device of the present utility model;
Among the figure: 1 attaching plug, 2 leads, 3 auto-power-off devices, 4 shells, 5 sheet metals, 6 jack AN1 button C1 electric capacity D1-D6 diode K1, K2 contact KM1, KM2 relay J 1, J2 joint T1 transformer
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is the Socket for computor of outage automatically, comprise attaching plug 1, lead 2, shell 4 and sheet metal 5, leave jack 6 on the shell 4, sheet metal 5 is installed in jack 6 bottoms, attaching plug 1 is by an end of lead 2 connection auto-power-off devices 3, and the other end of auto-power-off device 3 connects the sheet metal 5 of shells 4 inside by lead 2.
Auto-power-off device 3 can also be installed in shell 4 outsides as required.
As shown in Figure 2, the joint J1 of auto-power-off device of the present utility model connects attaching plug, and normally opened contact K1 is connected on the lead, is being in series with capacitor C 1, diode D6 and relay K M1 successively near between the lead of joint J1.Normally opened contact K2 is in parallel with button AN1, is connected then between diode D6 and the relay K M1.At the primary side near connection transformer T1 on the lead of joint J2, the secondary side of transformer T1 connects the input of the rectifier bridge of being made up of diode D1-D4, and diode D5 is in parallel with relay K M2, is connected on then between the output of rectifier bridge.Joint J2 connects sheet metal.
During start, press the button AN1, relay K M1 energising, the normally opened contact K1 closure that is associated with relay K M1 has been connected main circuit, and computer begins to start.Simultaneously, the secondary side induced voltage of transformer T1 makes relay K M2 get electric adhesive normally opened contact K2 associated therewith through the rectified action of diode D1-D4, and button AN1 no longer works, the main circuit continuous firing.After computer system was closed, main circuit current was reduced to about 0.1A, and transformer T1 secondary side induced voltage is very low, behind over commutation, was not enough to make relay K M2 to continue adhesive, and contact K2 disconnects, relay K M1 dead electricity, and contact K1 disconnects main circuit.During application, only need be closed computer system and be got final product, and socket will cut off the socket main circuit automatically behind system closing.
Relay K M1, KM2 can select different rated voltages for use according to the standby current size of peripheral hardwares such as computer and sound equipment, printer.
