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.
