Abstract
The invention relates to a multifunctional power supply adapter for a notebook computer with the functions of temporary electricity supply, supply interruption indication, energy saving and environmental protection. The power supply adapter comprises a common switch S at one end of an alternating current mains supply incoming line, a contactor attracting coil KM1 with an auxiliary action switch at the other end, a charging capacitor C1, an alarming circuit, a capacitor voltage stabilizing and reducing direct-current power circuit and a dual-core power access plug for connecting with a computer host. The adapter has the functions of electric power storage and static electricity consumption avoidance under the state of normal operation. The adapter has the functions of supplying electricity for a computer host temporarily and providing power interruption indication for a user under the state of the power supply interruption of the alternating current mains. The user can use the adapter more safely, simply and conveniently.
Description
Affiliated technical field
The present invention relates to a kind of power supply adapter for notebook computer, the especially a kind of multifunctional power adapter that can power temporarily, have outage prompting and energy saving and environmental protection effect.
Background technology
At present, the power supply adapter for notebook computer that circulates on the market is to adopt transformer step-down and function singleness.This power supply adaptor uses fairly simple convenience, also is easy to carry.But when sudden power and under the situation of not adorning cells in notebook computer, computer will shut down suddenly, this can cause certain injury to the hardware of computer, if the information that the user will just not operate on computer is preserved in advance, then these information be can lose, serious loss and inconvenience brought to the user; If do not need at computer and do not pull out the plug of power supply adaptor under the situation of normal shutdown, then can make power supply adaptor still be in "on" position and consume electrostatic energy, cause the unnecessary wasting of resources.
Summary of the invention
Deficiency for this power supply adaptor that overcomes current circulation, patent of the present invention provides a kind of multifunctional power supply adapter for notebook computer, this adapter not only has interim power supply, the function of outage prompting is provided in sudden power, but also has the effect of energy-conserving and environment-protective.
The technical solution adopted for the present invention to solve the technical problems is: the termination at the electric main electric power incoming line of traditional notebook computer power adapter is gone into a regular tap, the other end connects one and has the auxiliary moving contactor sucking coil that closes that disconnects, insert a charging capacitor at the two ends of inlet wire then, simultaneously an alarm in parallel and capacitance voltage stabilizing decompression DC power circuit, and connect the two core power supplys that are used to connect host computer and insert plug and get final product.
The invention has the beneficial effects as follows, when the electric main sudden power, the charging capacitor that has been full of electricity can be powered to host computer temporarily, and alarm also enters duty simultaneously, remind the user that the information of preserving is immediately also in time closed computer, so just retrieved user's unnecessary loss.And when the user need not use computer with its shutdown, can pull up the plug of power supply adaptor, and get final product and directly the regular tap of power supply adaptor is disconnected, so just reduced the static power consumption of power supply adaptor, reached purpose of energy saving.
Description of drawings
Fig. 1 is a circuit structure sketch of the present invention.
1. regular tap S among the figure, 2. alarm, 3. charging capacitor C1,4. contactor sucking coil 5. closes with supporting auxiliary moving disconnection of contactor sucking coil, 6. capacitance voltage stabilizing decompression DC power circuit, 7. two core power supplys insert plug.
Embodiment
In Fig. 1, one end A of electric main power supply meets a regular tap S, other end B meets a contactor sucking coil KM1, insert a charging capacitor C1 then at two ends, have auxiliary moving alarm 2 that closes KM1 and the capacitance voltage stabilizing decompression DC power circuit of forming by capacitor C 2, C3, resistance R, voltage stabilizing diode DW, commutation diode D 6 run jointly, and form two core power supplys access plug 7 connecting two output lead E, F that are used for linking to each other thereafter with host computer.Just formed circuit structure of the present invention thus.
When power supply adapter for notebook computer is connected on the electric main power supply, closed regular tap S, and two core power supplys are inserted plug 7 be connected on the host computer, main frame just can be started shooting and be entered duty, this moment, capacitor C 1 was in the duty of charging, and alarm 2 opens circuit because of the auxiliary moving pass KM1 that disconnects, and does not have the function of warning.After electric main power supply sudden power, the charging capacitor C1 that has been full of will power for host computer temporarily, alarm 2 also closes the closed warning of working of KM1 because of auxiliary moving the disconnection, after pointing out the user to preserve the information of handling as early as possible, in time carry out normal shutdown, the serious consequence of so just having avoided unexpected shutdown that the injury and the information dropout of computer hardware are brought.And when the user need not use computer with its normal shutdown, the user can pull up the plug of power supply adaptor incoming transport mains supply end, get final product and directly the regular tap S on the power supply adaptor is disconnected, this has just reduced static power consumption and the unnecessary trouble of user.
Claims (1)
1. multifunctional power supply adapter for notebook computer, it inserts plug by the capacitance voltage stabilizing decompression DC power circuit of electric main power inleting terminal with the two core power supplys that are used to be connected host computer and forms.It is characterized in that: at a termination one regular tap of electric main electric power incoming line, the other end connects and has the auxiliary moving contactor sucking coil that closes that disconnects, subsequently at inlet wire two terminations one charging capacitor, and in parallel one have the auxiliary moving warning circuit that disconnects the alarm that closes.
