Abstract
The utility model relates to a socket, in particular to a socket which is capable of automatically switching off power source of peripheral equipments while a host computer is switched off, thus avoiding electric power waste when users forget to switch off other peripheral equipments and the host computer has been switched off and abrasive aging due to long-term switch-on state for the equipments. The utility model utilizes power source provided by a computer USB interface to control an electromagnetic relay, thus controlling power switch-on/off over peripheral computer equipments.
Description
Technical field:
The utility model relates to a kind of socket, relates in particular to a kind of computer private jack that also can close the peripheral equipment power supply behind the host power supply of shutting down computer simultaneously automatically, and affiliated technical field is office electric equipment field.
Background technology:
Most equipment beyond the main frame all needs to provide separately power supply, as display, audio amplifier, external MODEM, printer, scanner etc., often forgotten to turn off simultaneously the power supply of these equipment behind the Shutdown Hosts power supply, allow these equipment be in "on" position for a long time, not only waste electric power resource but also make the equipment accelerated ageing.And present socket kind is a lot of but function is very single, the function of power source conversion only is provided mostly, existing smart jack waits the break-make of controlling power supply by setting-up time, telephone line often, these mode complex operations, and can not succinctly control the power supply of computer and peripheral equipment thereof intuitively, not reach the purpose of real-time control.
Summary of the invention:
At the defective of prior art in computer and the control of peripheral equipment power supply thereof, the utility model has been realized the purpose of Based Intelligent Control computer and the timely break-make of peripheral equipment power supply thereof.
The utility model is achieved like this: during the main frame operation, USB interface on the mainboard will be kept the operating voltage of one+5V, this voltage signal is lost behind the Shutdown Hosts, utilize this operating voltage to come the break-make of the electromagnetic relay in the control circuit board (3), and socket electrode (6) links to each other with control circuit board (3) respectively with (7), and socket electrode (6) is subjected to the control of electromagnetic relay just to realize the purpose of the real-time break-make of controlled device power supply.Socket electrode (7) is not subjected to the control of electromagnetic relay, is in normal open state, for the equipment that need not control provides power supply, as main frame etc.
For this reason, the technical solution of the utility model is: it comprises housing (1) a kind of computer private jack, total power switch (2), control circuit board (3), status indicator lamp (4) is formed, it is characterized in that being arranged on and have electrode jack (5) on the housing (1), be provided with in the electrode jack (5) and be convenient to the socket electrode (6) and (7) that are connected with plug electrode, the socket electrode (6) in the housing (1) is connected with control circuit board (3) respectively with (7).
Be provided with electromagnetic relay (8), USB interface (9) in the described control circuit board (3).
The specified loaded current of described electromagnetic relay is that 10A, specified carrying voltage are 250V.
Described indication respectively: USB control signal, alternating current 220V input signal, be subjected to control socket electrode alternating current 220V output signal, be not subjected to the status indicator lamp (4) of control socket electrode alternating current 220V output signal, constitute by D1, D2, four light-emitting diodes of D3, D4.
The components and parts of described computer private jack control circuit connect and circuit diagram is:
The utility model has the advantages that after having used computer, can automatically the peripheral equipment power supply together be closed when shutting down computer main frame, avoid the wear and aging of having forgotten behind the computer that having used the electric power resource of closing other peripheral equipment power supply and bringing is wasted and equipment is in "on" position for a long time and cause.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model outward appearance front view
Fig. 2 is the utility model outward appearance cutaway view
Fig. 3 is each pin function schematic diagram in the USB interface
Fig. 4 is the utility model control circuit schematic diagram
As shown in Figure 1, 2, the utility model is by housing (1), total power switch (2), control circuit board (3), status indicator lamp (4) is arranged on the electrode jack (5) on the housing (1) and is arranged on socket electrode (6) and (7) being convenient in the electrode jack (5) be connected with plug electrode and forms.Socket electrode (6) is connected with control circuit board (3) respectively again with (7), and the control of the electromagnetic relay (8) in the controlled circuit board of socket electrode (6) (3) has realized the real-time break-make of controlled device power supply.Socket electrode (7) is not subjected to the control of electromagnetic relay (8), is in normal open state, for the equipment that need not control provides power supply.
As shown in Figure 3, have four pins in the USB interface on the computer motherboard and be respectively: 1, DC+5V, 2, PORT-, 3, PORT+, 4, GND.Wherein 2 and 3 is the transfer of data pin, and 1 and 4 is supply pin, and the voltage that provides during the main frame operation is the 5V direct current, and electric current is 500mA.The utility model utilizes this power supply to control electromagnetic relay (8) exactly, realizes the break-make of power supply.
As shown in Figure 4, K is a total power switch, and F is the overcurrent protective tube; R1, R2, R3, R4 are current-limiting resistance, and the operating current of four light-emitting diodes is limited in 5mA-10mA; D1, D2, D3, D4 are light-emitting diode, indicate the on off operating mode of each road signal; C1, C2 are for the charged closed moment elimination contact spark of electromagnetic relay, reduce the high withstand voltage filter capacitor that surge current is established.Electromagnetic relay J selects for use 5V DC control 250V to exchange, and rated current is the high-quality electromagnetic relay of 10A, its rated power P=U*I=2500W, and for computer and peripheral equipment thereof, this power is enough.
Execution mode:
Link to each other with USB interface of the present utility model (9) with the USB interface of USB connecting line main frame, plug general supply, connect master switch K, socket electrode (7) is energising always just, for equipment such as main frame provide power supply, the electromagnetic relay of this moment is in off-state.When the main frame energized, the electromagnetic relay closure, socket electrode (6) energising is the computer peripheral power supply.After the main frame outage, electromagnetic relay returns to initial condition, and socket electrode (6) outage reaches the controlled purpose of computer peripheral.
