Description of the invention: [Technical field to which the invention pertains] The present invention relates to a kind of power supply device for the use of the end-of-sector power supply (four) components 种 - the type of conduction [first technology] = alternating current ' Axis ==:2 Ο Ο In order to respond to the different electric grinds required for various electrical products, there is a power supply 12 with an adjustable output voltage. The power supply is provided, and the toggle switch 14 connected to the turn-out wire changes the switch Μ inner resistor t, although it can replace the unnecessary change of the consumer _ changer two-touch probability gradually & south, the output is not generated Stable situation. And the electric switch can be switched by the switch 14 to change the output voltage, and the accidental touch may cause damage to the electric product, which causes the unsafe risk to be more serious. In addition, in order to reduce costs and reduce the volume of electrical appliances, the appliance manufacturer only designs a safety loop in the exclusive face, and must not use other converters other than the dedicated transformer. According to the notebook computer currently seen in the market, the voltage changes that it can withstand are often limited to only five percent of the voltage value. That is, if the voltage of the supplied electric energy exceeds this range, the internal circuit of the notebook computer will be damaged. If you don't carry the original accessories, or the original transformer transformers that are equipped with the original ones must be purchased separately, you have to buy the appropriate ones from the market, for those who are not familiar with the technology in this field. The composition is quite troublesome. On the other hand, in order to reduce costs, the transformers circulating in the market may not be designed with 201044157 circuit's more automatic warning when the output voltage is wrong; especially the quality is not good, that is, the ship has monitoring circuit, it may still happen. The sudden change of the electric energy voltage of the wind I electrical appliance forced the consumer to face the invention patent application No. 97106821 of Fig. Shen, and the output of the converter 3 can be output by the end component when the electric device needs to be charged. In other words, the indoor socket 8 is electrically connected to the transformer body 30 via the plug 32, and transmitted to the mobile phone 91 for charging by using the 々 Ο 辑. In the static (4) case, the end of the towel 'silk tillage as a control = device, so that the child can be charged regardless of the state of charge or voltage is not ideal == the Ministry will continue to consume electricity, on the one hand does not meet the trend of environmental protection, and other aspects continue to heat May cause additional problems. Use the mouth for consumers to choose, and compared with the portable electric appliance ^^_, the volume is very small and easy to lose, to ensure that by any transformer to brain transmission (four) electrical energy transmission ^, its, is inevitably stable, She does not need to use = ah, do not need to spend extra ^ in the state of not charging, the converter changes the output voltage by itself until it meets the best solution for the choice of interests. It will become a guarantee 4 fee. [Invention] The intended purpose is to provide an end-of-life component that is extremely safe and does not meet the expected power supply. Another object of the present invention is to provide an end piece for a power supply device which is simple in structure and small in size and which is compact and convenient for portable electric appliances. Cheng, the purpose of the provision of a kind of hybrid electric power active components, does not consume unnecessary electrical energy and meets the environmentally friendly end parts of the power supply device. 4 201044157 ★ Re-purpose 'in the offer - kind of holdable, (four) control output power / electricity ": immediately block the power supply" to ensure that electrical appliances are not damaged by the supply _ Ben = have = end in the Ministry and then - The purpose is to provide a kind of end component that is not allowed to change (4) until the obsolescence, the variable commutator body can change the output by itself, and set the 'spinning wire, the surface assurance system and the safe power supply assembly. A power supply device =: a variable voltage output of the output voltage output power of the cattle should have: ΐίΓ s can be a power device, the end parts include: the wire of the wire & · Hi line ί - root fresh material line, wealth The power output of the wheel: one = the output of the electric energy meets the predetermined iron circumference = non; and the electric energy from the electric wire group is allowed to be transmitted to the electric power installation, and the electric power can be installed. For the pressure body; a set of turns to the power device: root height = line: a low-referred to activate the switch unit. When the non-active component group is closed, The invention disclosed in this case, the voltage and current specifications of the utensils, the choice of the person according to the electricity 20104415 7 The electrical appliances ensure the quality of each power supply; more non-active components are used in the end parts to avoid unnecessary power consumption in the non-conducting condition. ^These parts are simple in circuit and low in cost. The small size does not damage the portability of electrical appliances. Therefore, when consumers cherish some electrical appliances, they can choose the safety output device that guarantees the specifications of the appliance. From the unscrupulous match with any power supply device There is no need to worry about the stability of each power supply device itself. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be clearly described in the following with reference to the preferred embodiment of the reference formula. For convenience of explanation, the description of the embodiment of the present invention will follow the example shown in FIG. 2, and the power supply device is exemplified as the _converter 3' and the electric device is left as the mobile phone 9. Of course, it can be easily understood by those skilled in the art. Here, the transformer can be replaced by an external rechargeable battery, and the power device can be changed to a notebook computer or a personal digital processing device (PDA). Or any other similar product. As shown in Fig. 3, the end piece 2 disclosed in the embodiment has a set of wire sets 21, a set of non-active component sets 23 and a switch unit. The wire set 21 comprises at least one wire. The high-level wire 211 for receiving the electric energy supplied from the outside, and the low-level wire 213 for grounding; the non-active component group 23 includes the capacitor and the Zener diode 23 as the load member 233. a resistor, and an NPN-type transistor 235, the base (10) of the transistor 235 is connected between the Zener diode 231 and the load member 233; and the switch unit 25 in this example is one When the voltage electric energy value meets the predetermined voltage range (for example, a power supply of 16.5 volts), the non-active component group 23 is activated, and the electric energy from the wire group 21 is allowed to be transmitted to the electric device via the wires 271, 2γ3. The integrated circuit element 251. When the n-axis impurity 21 input terminal 2 from the transformer body (not shown) passes through the capacitor between the high-position wire 211 and the low-position wire 213, the high-frequency portion of the input power towel is turned to the ground. The remaining DC components are input to the 201044157 non-active component group 23. In this example, for example, a Zener diode 231 ' having a breakdown voltage of 16.5 volts is selected and electrically connected to the high-level wire 211 at the wheel end, and the input terminal is electrically connected to the low-position wire 213 to be reversely disposed. Therefore, when the voltage Vcc from the high-level wire 211 is less than the predetermined 16.5 volts, the Zener diode 231 directly conducts the blocking current to the grounded low-level wire 213' to cause the Zener of the low-level wire 213 to be connected. The input terminal of the diode 231, the load member 233, and the base 2350 of the transistor 235 are both equal to the potential of the ground point, and the collector and emitter of the transistor 235 are thus disconnected, so that the base potential of the subsequent transistor 237 is Vcc 'electric After the collector and emitter of the crystal 237 are turned on, the potential of the collector 2371 is lowered to a low potential, and the fourth pin of the integrated circuit component 251 is input as a low level signal, and the component 251 blocks the current from Micro Motion. The bit line 211 is transferred to the wire 271. If the input power voltage is greater than 16.5 volts, the reverse-set Zener diode 231 will collapse and conduct. At this time, the base 235 of the transistor 235 reaches a high level, and the collector and emitter of the transistor 235 are turned on. The collector is electrically connected to ground, and the potential drop to a low level also causes the base of the transistor 237 to drop to a low level, and its collector 2371 and the emitter open 'collector 2371 potential are close to Vcc, so that the integrated body The fourth pin of the circuit π 251 inputs a high level signal, so that the switch unit forms a path 'outputs the input electric energy from the high level wire 211 to the electric device (not shown) via the wire 271. With such a control structure, it is possible to block a voltage that is too low and not in accordance with the expected input power, and in particular, the non-active component group 23 does not consume power when it is not turned on. Conversely, 'If you want to protect the electrical device from excessive voltage attack, you can easily choose - for example, the fourth pin will enter the low-level signal to turn on, and the input high-level signal will be disconnected. In the example, the unit 25 can achieve the above purpose. Of course, 'familiar with the technical field, when you need, for example, 19 volts DC to input human energy, 'can also choose - the group voltage is not higher than 19 5 volts to conduct the $ road and - group voltage is not lower than 18 5 scales to conduct the circuit In series, in order to ensure the accuracy of the input power by the pressure and the two-way door. 201044157 Of course, the structure of the non-active component can also be changed as shown in FIG. 4, and the npn-type transistors 235 and 237 are changed to the field-effect transistors 235, 237, or as shown in FIG. The same effect can be achieved by changing to relay 253. In addition, the above input voltage is lower than the predetermined safety threshold to be turned on. As shown in FIG. 6, when the voltage of Vcc is too high and the Zener diode 231 collapses, the base 2350 of the transistor 235 becomes high. At the level, the collector and the emitter of the transistor 235 are thus turned on, and the relay 253 is connected to the collector 235 to become a low level at the collector pin, and a magnetic field is generated in the coil of the relay 253 to disengage the high-position wire 211. The wire 271 is broken, thereby blocking the passage of excessive voltage. The so-called non-active components in this case are not limited to, for example, Zener diodes. Since the voltage across the two ends of the light-emitting diode does not reach a predetermined threshold (for example, 24 volts), no current is allowed to pass, and the potential difference between the two ends must be equal. At 24 volts, a small amount of current flows through the beginning. Therefore, the fifth embodiment of the present invention, as shown in FIG. 7, is a light-emitting diode 231 that is connected by three forward high-level wires 211" and a low-position wire 213". In place of the Zener diode of the foregoing embodiment, when a voltage of, for example, 9 volts is transmitted from the J-position wire 2H" in the wire group 21, there will be a current flowing through the load member 233", the transistor 235" The base 2350" thus becomes a high level, and its collector and emitter are turned on as the integrated circuit element "I of the switching unit 25", and the potential of the fourth pin is thus at a low level, and the switch is thereby blocked. Conversely, when Vcc is lower than, for example, 7.2 volts, no current flows through the light-emitting body 231 'base 2350' to a low level, the collector and the emitter are disconnected, and the collector potential is close to Vcc' such that the integrated circuit components 251, the fourth foot is high level, high level wire 211" The transmitted electric energy is thus transmitted to the wire. The non-wire component of the present invention is in the unconducted state and consumes only a small amount of electric energy. In terms of power consumption, it meets environmental protection requirements, and when the power supply device is mainly charging electricity or a pool. In order to provide convenience to the user, the transformer body of the present embodiment includes an input port 301, a transformer unit 302, an output port 3〇3, and a control unit 3 as shown in FIG. 〇4, the feedback terminal 305 of 201044157, the clock generator 306, and a group of selection control units 3〇7, wherein the input electric energy enters the transforming unit 3〇2 from the input port 301, and is converted and output 埠303 The output is to the end component of the present invention. In this example, as shown in FIG. 9 together, the wire set of the end component includes a feedback wire in addition to the high-level wire 211 and the low-position wire 213 of the above embodiment. 215, for example, when the electric device adopts the electric device 9' of the 19 volt county and selects the resistance H of the control unit 3〇7 to be the same as the resistance value of each other, and the same electric power (4) is connected to the transformer 放大器ί amplifier Phase input, with amplifier inverting input The resistance on one side produces different ratios, which changes the output voltage of the output 。. Ο 单元 The surface element view may be output from the originally set minimum output η μ 1%, when the inactive component group 23 and ϊΐ ΐϋ 当If the power is blocked from being transmitted to the power device 9, the sensor 27 will not be able to provide any signal to the feedback terminal, such as the feedback terminal 3G5 of the it5, so that the signal will not be received, and the selected control unit is turned on.

' ah order change ' will output the voltage protection of the end parts, according to the power generation can be used to match the position of the appropriate input, the self-changing J transformer * body will be output after the output of the financial output until the ink is correct, provide The user has great convenience and security of 201044157. Of course, the end member is not limited to being disposed on the side of the electric device, and the electric device can be a computer 92, as shown in Fig. 1A. And the internal loop structure of the above-mentioned variable county body, or the end component feedback = road design 'because of the secondary technical features of this case' is not the main technical feature of the case, for example, the switching output voltage is switched by using, for example, PWM or other similar control methods. To the ideal value, it is still within the scope of this case. Take this ^
