Abstract

The utility model relates to an electric source socket for the computer and the peripherals of the computer, comprising an insulating casing. The casing is provided with a plug jack. The socket is provided with an electric source input line. The utility model is characterized in that the electric source socket has two sets of output lines; one set of output line is directly connected with the input line; the other set of output line comprises a switch control circuit comprising a USB 5V output electric source of the computer and a relay. The normally open contact of the relay is arranged on the electrode of the fire line; the USB 5V electric source of the computer is connected with the coil of the relay. When using specifically, the electric source line of the computer is directly inserted on the first set of output line, and the electric source lines of the other electric equipment are connected to the second set of output line. When the computer is turned off, the USB 5V output of the computer is powered off, the normally open contact of the relay is turned off, at this time, the second set of output line is powered off, and the peripherals matching the computer inserted on the second set of output line are automatically powered off. When the electric source of the computer is turned on again, the output line returns to the original state again, realizing the purpose of turning off the electric source of all the equipment by operating one key.

Description

A kind of supply socket

Technical field

The utility model relates to a kind of supply socket, particularly a kind of supply socket that is used for computer and supporting peripheral thereof.

Background technology

Supply socket of the prior art comprises that fixed supply socket is as being contained in supply socket and portable supply socket such as the wiring board etc. on the wall, its structure all comprises an insulator shell, on shell, have jack with the plug coupling, be respectively equipped with firewire electrode, zero wire electrode and ground line electrode with each jack corresponding position in the housing, each homonymy electrode is connected in parallel.During use, live wire, zero line, the ground wire of extraneous power supply received respectively on firewire electrode, zero wire electrode and the ground line electrode of socket, thereby obtained electric energy.The deficiency that such supply socket exists when being used for computer equipment is must be one by one with the power-off as power consumption equipments such as display, stereo sets after main frame is closed, operating process is loaded down with trivial details, often because of forgetting that powered-down makes these equipment still be in holding state, not only wasted electric energy but also dangerous.In addition, the supply socket that has only limits to provide power interface, hand switch, electric leakage and the overload protection function of expansion power consumption equipment, can not satisfy the requirement that simple operations can be turn-offed whole power consumption equipment circuit.

Summary of the invention

The purpose of this utility model is to provide a kind of supply socket that is used in particular for computer and associated peripheral thereof, and simple operations can be cut off the power supply of whole power consumption equipments, has remedied the defective of prior art.

In order to realize that the technical scheme that the purpose of this utility model is taked is such.A kind of supply socket, comprise an insulation shell, have jack on the housing, be respectively equipped with firewire electrode, zero wire electrode and ground line electrode with each jack correspondence position in the housing, be characterized in that it has two groups of outlet lines, one group of outlet line directly is connected with incoming line, another group outlet line comprises an ON-OFF control circuit of being made up of computer USB 5 volts of out-put supplies, relays, the normally opened contact of relay is arranged on the firewire electrode, and 5 volts of power supplys of the USB of computer are connected with the coil of relay.

Supply socket of the present utility model, further characteristics are that described ON-OFF control circuit is to be made of 5 volts of out-put supplies of computer USB and controllable silicon.

Supply socket of the present utility model, its further characteristics are to be equipped with the multi-group power jack on two groups of outlet lines.

For easy to connect, this supply socket is provided with extraneous attaching plug and 5 volts of power connections of computer USB.

The course of work of the present utility model is as follows: extraneous power supply inputs to socket, first group of outlet line OUT1 directly is connected with incoming line, when concrete the use, the computer power supply line directly is inserted on first group of output line OUT1, other power consumption equipment power line is connected on second group of output line OUT2, during computer operation, 5 volts of output of computer USB electric energy, the relay normally open contact k ' 2 that is located on the live wire L of second group of outlet line is in open mode, live wire L conducting, second group of outlet line OUT2 has electric energy equally, after computer cuts out, and 5 volts of output outages of the USB of computer, the normally opened contact K ' 2 of relay closes, at this moment, the live wire of second group of outlet line does not have electric energy, cuts off the power supply automatically so be plugged on second group of computer supporting peripheral on the outlet line.When opening computer power supply once more, outlet line OUT2 restores to the original state again, has electric energy to pass through, and repeats the purpose that other supporting peripheral power supply turn-offs simultaneously when having realized shutting down computer successively.

The utility model has the advantages that and realized computer peripheral one-key operation when computer booting and shutdown, not only save the energy but also made things convenient for the operator, reduced potential safety hazard because of forgetting that powered-down causes.

Description of drawings

Fig. 1 is a circuit structure schematic diagram of the present utility model.

Fig. 2 is that switching circuit is the circuit structure schematic diagram of controllable silicon form.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Referring to Fig. 1, supply socket has insulation crust, built-in electrode, computer USB 5V joint and extraneous power connection, in insulation crust, be provided with ON-OFF control circuit, be respectively equipped with firewire electrode L with each jack correspondence position in the insulation crust, zero wire electrode N and ground line electrode E, socket has power input line road AC220V IN, on the live wire L of incoming line, be provided with hand switch K1 and fuse F, this supply socket has two groups of outlet lines, first group of outlet line OUT 1 directly is connected with incoming line AC220V IN, another group outlet line OUT 2 comprises one by 5 volts of out-put supplies of computer USB, relay K 2, the ON-OFF control circuit that K ' 2 forms, the normally opened contact K ' 2 of relay is arranged on the firewire electrode L, and the USB 5VIN power supply of computer is connected with the coil of relay K 2.

As shown in Figure 2, the relay in the switching circuit among second group of outlet line OUT 2 of supply socket is replaced by controllable silicon, and its operation principle is identical with the embodiment that Fig. 1 provides.
