An outside mains supply is connected with the power supply circuit through the input socket. The computer power supply further comprises a relay and at least one output socket, a coil of the relay is connected with the output end of the power supply circuit, a zero line/firing line end of the input socket is correspondingly connected to a zero line/firing line end of the output socket, and a normally open contact of the relay is in series connection with a position between the zero line ends or the firing line ends of the input socket and the output socket. The output socket is installed on the shell. The computer power supply enables a power supply input end of an external connection device of a computer to be conveniently and directly connected to the computer power supply so as to obtain power supply to work.

Description

A kind of computer power

Technical field

The utility model relates to supply unit, especially a kind of computer power.

Background technology

The power supply of the PC computer that uses at present comprises housing and the feed circuit that are installed in the housing, and these feed circuit convert mains supply (220V alternating current) to direct current and supply the PC main frame to use, and wherein, the input socket that is used to import external power source is installed in housing; Use computer power when external other peripheral hardwares of needs (like printer, display, sound equipment etc.), must plate of extra increase or a plurality of plate come to supply power to peripheral hardware, make troubles to the user, and in disorder winding displacement is not attractive in appearance.And most of users use up computer directly do not have initiatively after the shutdown yet outside the Pass the custom of plugboard, can bring peripheral hardwares such as printer, display, sound equipment to continue holding and power consumption like this, the waste electric power resource.

The utility model content

The purpose of the utility model is to provide a kind of computer power, the power input of the external equipment of computer can be directly connected to easily obtain power supply on the computer power and work.

The purpose of the utility model realizes through following technical scheme: a kind of computer power; Comprise housing; Be installed on the feed circuit in the housing and be installed on the input socket on the case side panel; Outside mains supply is connected with feed circuit through input socket, it is characterized in that: also comprise a relay and at least one accessory power outlet; The coil of said relay is connected with the output terminal of feed circuit; Corresponding zero line/live wire the end that connects accessory power outlet of the zero line of said input socket/live wire end, the normally opened contact of said relay is serially connected between the zero line side or live wire end of input socket and accessory power outlet; Said accessory power outlet is installed on the housing.

The line bag two ends of the said relay of the utility model also are connected to voltage stabilizing diode.

Between the live wire end of the zero line side of the said input socket of the utility model and input socket and be connected to electric capacity.

The said accessory power outlet of the utility model mutually and connect.

Said input socket of the utility model and accessory power outlet all are installed on the same side panel of housing and constitute plate.

Compared with prior art, the utility model technology has the following advantages:

1, convenient external miscellaneous equipment, the input end of the external equipment of computer can directly be inserted in easily and obtain power supply on the accessory power outlet of this computer power and work, and make that also the power lead winding displacement of computer and peripheral hardware is succinctly attractive in appearance.

2, realize that through relay a key closes computer and peripheral hardware simultaneously, the power supply of peripheral hardware is in time closed, with energy savings.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

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

Embodiment

As shown in Figure 1; A kind of computer power comprises housing, is installed on the feed circuit in the housing and is installed on the input socket 1 on the case side panel; Outside mains supply (AC220V) is connected with feed circuit through input socket; Also comprising three accessory power outlets 2, is respectively a 2pin socket and two 3pin sockets, and the number of accessory power outlet and the pin pin type of accessory power outlet also can be set as required;

Accessory power outlet and input socket all are installed on and constitute plate 3 on the same side panel of housing, also can as required accessory power outlet and input socket branch be located on the different side panels; Between three accessory power outlets mutually and the corresponding zero line/live wire end that connects input socket of the zero line after connecing/live wire end; Ground connection after the ground wire of the socket of two 3pin links together.

As shown in Figure 2; This computer power also comprises relay K T; The coil of relay K T is connected with the output terminal of feed circuit, relay /dead electricity and feed circuit are synchronous, and the normally opened contact KT1 of relay K T is serially connected between the zero line side of input socket and accessory power outlet; Also can be serially connected between the live wire end of input socket and accessory power outlet, with getting/dead electricity of control accessory power outlet.

The line bag two ends of relay also are connected to voltage stabilizing diode D1, to play voltage stabilizing purpose and the back-emf of eliminating relay coil.Between the live wire end of the zero line side of input socket and input socket and be connected to capacitor C 1, this capacitor C 1 is a safety electric capacity, to play voltage stabilizing and filter action.

As shown in Figure 2, behind the power switch K4 that presses host computer, computer power normally starts; Feed circuit are imported outside 220V alternating voltage; Output+12V DC voltage, relay K T coil gets electric adhesive, and its normally opened contact KT1 is closed; Make accessory power outlet K1, accessory power outlet K2, accessory power outlet K3 output AC220V voltage on the plate, this moment, peripheral hardware can obtain power supply through these three sockets easily;

When the power switch K4 of host computer breaks off; The computer power dead electricity, promptly feed circuit do not have+output of 12V DC voltage, and relay K T resets; Its normally opened contact KT1 breaks off; Make accessory power outlet K1, accessory power outlet K2, accessory power outlet K3 dead electricity on the plate, three sockets and feed circuit are dead electricity simultaneously, reaches the purpose that a key is closed armamentarium.

The embodiment of the utility model is not limited thereto; According to foregoing; Ordinary skill knowledge and customary means according to this area; Do not breaking away under the above-mentioned basic fundamental thought of the utility model prerequisite, equivalent modifications, replacement or change that the utility model can also be made other various ways all can realize the utility model purpose.
