Abstract
The utility model relates to a full turn-off protector for computer, comprising a casing and an internal circuit. The internal circuit comprises a two-way tumbler switch K, a relay J and a control circuit of the relay J. The normally open contact J1-1 of the relay is connected in series with the alternating current supply return circuit of the host computer power supply. The control circuit of the relay J comprises a source triggering power supply return circuit of the relay coil regarding one switch of the two-way tumbler switch as the conductive switch and a maintenance power supply return circuit of the relay coil connected with the direct current output end of the host computer power supply. The other switch of the two-way tumbler switch still serves as the triggering conductive switch of the computer mainboard. The utility model can realize the current-time turn-off of the 220 V alternating current input when turning off the computer, that is to say, realize the full turn-off of the computer. The utility model is needed to be connected to the host computer simply, having reasonable and simple design.
Description
Technical field
The utility model relates to a kind of main frame power supply auxiliary equipment, is specially the computing machine pass protector that cuts off the power supply entirely.
Background technology
Active computer shutdown back (but not turn-offing 200 volts AC power), in fact computing machine is in the soft-off state, and host power supply this moment (ATX power supply) still is in electriferous state, consumed power not only, and easily cause the computing machine damage because of the line voltage instability.
Summary of the invention
The utility model solves can not the cut off the power supply full problem of shutdown of active computer, and a kind of computing machine pass protector that cuts off the power supply entirely is provided.
The utility model is to adopt following technical scheme to realize: the computing machine pass protector that cuts off the power supply entirely, comprise housing and internal circuit, internal circuit comprises the control circuit of a two-way tumbler switch K, relay J and relay J, and the normally opened contact J1-1 of relay J is serially connected with the ac power supply circuit of main frame power supply; The control circuit of relay J comprises the current supply circuit of keeping of the relay coil that links to each other with dc output end with host power supply (ATX power supply) as the active triggering current supply circuit of the relay coil of actuating switch with one of them switch of two-way tumbler switch, and another switch of two-way tumbler switch is still as the triggering and conducting switch of computer motherboard.Press two-way tumbler switch K (moment), battery in the control circuit of relay J triggers power supply to relay coil, the normally opened contact closure of relay, the ac power supply circuit conducting of host power supply, host power supply work, the simultaneous computer mainboard is started working under the triggering of two-way tumbler switch, and the direct current output (12 volts) of host power supply is kept power supply to relay coil, to guarantee the adhesive of its normally opened contact in the computer booting process.During the computing machine normal shutdown, host power supply is subjected to operating system control shutdown, the power supply voltage of keeping of relay coil makes zero, the relay coil dead electricity, its normally opened contact disconnects, the ac power supply circuit of host power supply disconnects, and computing machine is disconnected with 220 volts of alternating currents fully, realizes the full outage shutdown of computing machine.
The control circuit of relay J is exactly charged, dead electricity, the disconnection of contact, the closure of pilot relay, its circuit structure is to electricity field, particularly the technician of electric control field is the known technology of realizing very easily, and multiple circuit structure modification can easily be arranged.The utility model has provided a kind of particular circuit configurations of control relay circuit in embodiment.
The utility model can be realized disconnecting the now of computer shutdown 220 volts and exchange input, promptly realizes the full outage shutdown of computing machine.It is reasonable in design, simple, only it need be connected in the main frame simply to get final product.

Embodiment
The computing machine pass protector that cuts off the power supply entirely comprises housing and internal circuit, and internal circuit comprises the control circuit of a two-way tumbler switch K, relay J and relay J, and the normally opened contact J1-1 of relay is serially connected with the ac power supply circuit of main frame power supply P; The control circuit of relay J comprises the current supply circuit of keeping of the relay coil that links to each other with dc output end with host power supply (ATX power supply) as the active triggering current supply circuit of the relay coil of actuating switch with one of them switch of two-way tumbler switch, and another switch of two-way tumbler switch is still as the triggering and conducting switch of computer motherboard.
Active triggering current supply circuit in the control relay circuit is formed by connecting by diode D1, two-way tumbler switch K, capacitor C 1, the diode D2 in parallel with relay coil J, keeps current supply circuit and is formed by connecting by diode D3, resistance R 1.It is instantaneous to press two-way tumbler switch K, battery E is to capacitor C 1 charging, after two-way tumbler switch is decontroled, capacitor C 1 is through the coil discharge of relay J, make that relay coil is charged, normally opened contact J1-1 closure, behind 220 volts of alternating current normal power supplies, the output of the direct current of host power supply P is kept power supply through diode D2, resistance R 1 to the relay J coil.
Also be provided with the battery charge loop that is formed by connecting by diode D4, resistance R 2, voltage stabilizing diode D5 in the control relay circuit.Computing machine is normal start after, the direct current output (12 volts) of host power supply P through charge circuit to battery charge.
Two-way tumbler switch in this protective device is fixed on the host panel.5 internal circuit extension lines are arranged on the housing, i.e. the extension line at the normally opened contact J1-1 two ends of relay J is used for an extension line linking to each other with the host power supply dc output end, is used for two extension lines that link to each other with two-way tumbler switch (one of them switch).
Two-way tumbler switch adopts the doubly-linked touch-switch.Battery in the control relay circuit adopts 9 volts of stacking rechargeable batteries.
