Identification switch for power supply and the power supply

The present invention relates to a multi-selection switch, and more particularly to an identification switch for a power supply and the power supply.

With the advancement of modern technology, many electrical appliances have been miniaturized and digitized, so that the power supply that can convert the output power of power plants into voltages and currents suitable for various household appliances cannot be built in miniaturization or portable. In electrical products. Coupled with the commercial considerations of various electrical appliance manufacturers, the power supply specifications, even the battery that can be integrated with such electronic products such as notebook computers and mobile phones, are exclusively dedicated, and even cannot be produced with the same company. The other models are interchangeably used, resulting in at least several or even dozens of different sizes of batteries and power supplies for each household or even each consumer.

In view of this, the market has introduced a power supply that can switch a variety of output voltage options by switching, in order to greatly reduce the number of power supplies, while reducing the inconvenience of traveling abroad or traveling.

However, as shown in FIG. 1, a conventional power supply 1 with an adjustable output voltage has a body 11 that changes the resistance of the resistor in the toggle switch 14 by a toggle switch 14 connected to the output conductor. And selecting a voltage value for switching the power output to the output terminal 13. This combination can only provide the effect of voltage conversion, and can be switched and changed by the toggle switch 14 when the power supply 1 of the output voltage can adjust the output voltage. In conclusion, if the toggle switch 14 is accidentally touched, the power product may be damaged or even cause a safety problem; in particular, after a long period of use, the lever 15 in the toggle switch 14 will be loosened due to long-term movement, causing occurrence The chance of accidental touch is gradually increased, thereby increasing the risk of unstable output.

In addition, with the current increase in portable portable appliances such as notebook computers and mobile phones, some electrical products such as the iPod introduced by Apple Computer do not have a rechargeable battery that can be disassembled and replaced by itself. Once the dedicated battery built in the fuselage is damaged, It takes time to send the original factory for repair. Subsequently, some battery manufacturers have introduced multi-purpose external batteries, which are used as backup power supplies on the one hand, and can be directly used externally when the built-in battery is damaged, thereby reducing the above inconvenience. And because the external battery needs to match various voltage requirements and different plug sizes, not only must the output voltage be switched, but also the replaceable connector of the current power supply, so there are also the above stability problems of the power supply. .

Therefore, if a power supply with a recognition switch can be provided, not only the switched power supply can be fixed, but also the voltage or current of the output can be changed by different driving devices, so that the user can hold only most of the power supply. The electricity demand of electrical appliances does not need to "collect" a variety of batteries or power supplies, and the output voltage can be changed by plugging and unplugging different driving devices, thereby reducing the loosening or mis-touching of the toggle switch 15 14 risk. Moreover, the driving device is simple in manufacture, low in price, small in size, easy to carry, and free from electromagnetic interference, ensuring and recognizing the power supply that is enabled and supplied with stable power supply, such as in the transmission of electrical energy to electrical appliances. Specifications to ensure the safety of electrical appliances. Such a power supply identification switch and the power supply should be the best solution to protect consumers' choice of rights.

The foregoing and other objects, features, and advantages of the invention are set forth in the <RTIgt; For convenience of description, in the following preferred embodiments, a single driving piece will be used to represent the driving device, and the driving relationship between the driving device and the switch body will be explained. The power supply device is respectively illustrated as a power supply or an externally rechargeable battery.

In the first embodiment of the identification switch 3 of the present invention, as shown in FIGS. 2 and 3, there are mainly five conductive electrodes 32 spaced apart from each other, five corresponding flexible conductive terminals 34, and a driving blade 5. And defining a direction in which one end of the flexible conductive terminal 34 extends is a long direction L. In this example, the conductive electrode 32 also extends along the same length and one-to-one corresponding to the flexible conductive terminal 34. For the sake of explanation, the portion where the flexible conductive terminal 34 is used to contact the conductive electrode 32 or the driving sheet 5 to form a via is the contact 348, and the conductive electrode 32 is in contact with the contact 348 or the driving sheet 5 to form a via. The portion is the conductive contact portion 328; and the direction substantially perpendicular to the longitudinal direction is defined as the angle V in the angle. In this example, the initial state of the identification switch 3 is that all the conductive electrodes 32 and the flexible conductive terminals 34 are not turned on, that is, each set of corresponding flexible conductive terminals 34 and conductive electrodes 32 are formed with an interval in the above-mentioned angle direction. And make the initial state non-conductive state.

As shown in FIG. 4, the driving piece 5 includes a driving body 52 and a driving tooth portion 54 for the user to hold the driving body 52 and insert the identification in a direction substantially parallel to the long direction toward the flexible conductive terminal 34. In the switch body, the driving tooth portion 54 has different shapes according to different designs, and has at least one pushing tooth 542 therein. In this example, as shown by the broken line, each pushing tooth 542 has a tilt guide away from one end of the driving body 52. Since the sliding surface 544 is formed, a total of five push-out teeth 542 respectively corresponding to the flexible conductive terminals 34 can be disposed on the one-piece plastic driving sheet 5 as shown in this example.

Furthermore, when the driving piece 5 is inserted from the starting position 42 from the insertion opening 6 at the upper left of the dielectric housing 7 in parallel with the long-distance insertion switch body, the inclined sliding surface 544 at which the pushing-out tooth 542 is disposed will be downward. The corresponding flexible conductive terminal 34 is pushed until it reaches the predetermined driving position 44 indicated by the broken line, and one end of the flexible conductive terminal 34 away from the opening contacts the conductive electrode 32 to form a conductive state indicated by a broken line. And by pushing and extracting the position distribution of the teeth, the on and off of the corresponding conductive electrodes 32 and the flexible conductive terminals 34 of all the groups in the identification switch 3 can respectively form the effects of encoding 1 and 0, resulting in, for example, 11111. A set of signals. In addition, in FIG. 2, the identification switch 3 further includes a set of locking/ejection devices 8, which include a push rod 82 (indicated by a dashed box) and an elastic member 81 for driving the push rod 82 to drive The sheet 5 can be locked when first pushed to the predetermined drive position 44 and pushed backwards when the drive sheet 5 is pushed inward a second time.

Therefore, as shown in FIG. 5, the identification switch is disposed in the power supply 10, wherein the identification switch 3 located at the lower right of the input port 21 of the power supply 10 has a driving piece 5 inserted therein for driving the power supply. A switch in the housing. This case The circuit of the power supply is as shown in FIG. 6, wherein the conductive electrode 32 and the flexible conductive terminal 34 will change the conduction state according to the driving signal of the driving piece 5, affecting the voltage changing selection circuit 16; when the power is input from the input port 21 The main body 12 changes the output voltage by the identification switch 3 instructing the transformation selection circuit 16, and outputs it via the output port 22.

Of course, those skilled in the art can easily understand that the above description is only for convenience of description. The identification switch is not limited to the voltage that can only be built in the power supply main body and switches the power supply; and the driving piece is not limited to homogenization. The non-conductive non-magnetic material and the access position of the identification switch are not unadjustable, and the configuration and relative position of the conductive electrode and the flexible conductive terminal can also be changed according to market demand. Therefore, as shown in FIG. 7, the initial state of the identification switch 3' in the second embodiment of the present invention is that the contact 348' of the flexible conductive terminal 34' has touched the conductive contact portion 328' and is in a conducting state, so that the identification switch is enabled. The initial state of 3' is that all sets of terminals are in a conducting state. In this example, the inclined sliding surface 544' of the driving piece 5' is curved into a curved convex shape and is injection molded from a non-conductive plastic material, and the insertion opening 6' of the switch is disposed at the center of the right side, when the driving piece is When 5' is inserted into the predetermined driving position, the applied flexible conductive terminal 34' is pushed to the non-conductive position, and the applied flexible conductive terminal 34' is separated from the conductive electrode 32' to form an open circuit. That is, the original output of the power supply 10' can preset a common voltage and current value, and can still supply a common electric appliance with a preset power supply without the driving piece 5' interposed, and use the driving piece for special needs. 5' switch identification switch 3'.

Referring to FIG. 8 together, in this example, the eight sets of corresponding conductive electrodes 32' and the flexible conductive terminals 34' provided by the identification switch 3' are set with three pairs of conductive electrodes 32'-flexible conductive terminals 34'. The current is adjusted, and the other five pairs of conductive electrodes 32'-flexible conductive terminals 34' are exemplified for adjusting the voltage. Each of the flexible conductive terminals is connected at one end to a different pin of the microprocessor 17', and the microprocessor 17' outputs a signal to the voltage varying selection circuit 16' in the power supply 10'. Therefore, when the identification switch 3' is driven, the information about the related conduction and disconnection will be transmitted to the microprocessor 17', and the voltage-variable selection circuit 16' is adjusted with the result of the interpretation of the microprocessor 17' to output the required voltage, Current.

Referring to FIG. 9, the driving piece 5" has a conductive portion 56" which is connected to the body 52" and made of a conductive material 562" made of a material such as metal or graphite. The driving piece 5" activates the signal of the identification switch. 1010101 from top to bottom. As shown in FIG. 10, the flexible conductive terminal 34" and the conductive electrode 32" are oppositely spaced apart from each other in the initial direction, and are not in contact with each other only in the conductive portion 56". The driving piece 5" of the conductive tooth 562" is moved to the predetermined driving position 44", and the flexible conductive terminal 34" and the conductive electrode 32" are abutted up and down along the angle direction, as shown by a broken line, to form an electrical path.

In a fourth embodiment, as shown in FIG. 11, the conductive contact portion 328"' of the conductive electrode and the corresponding flexible conductive terminal contact 348"" are spaced apart from each other along the long direction, and are formed by covering with a thin layer of conductor. The driving piece 5 ′′′ of the conductive tooth 562 ′′′ extending along the long direction is located at a predetermined driving position 44 ′′′, and the identification switch is driven, and the conductive contact portion 328 ′′′ and the corresponding contact can be simultaneously guided. 348''' and the two form a pathway.

Of course, the driver chip can only change the voltage and current in order to avoid any accident or human error, causing foreign matter to invade the switch and touch the conductive electrode/flexible conductive terminal to change the original state, causing unknown danger. A portion of the conductive teeth act as a "key" that actually drives the switch. As shown in FIG. 12, three kinds of octave driving sheets 5''' are illustrated, and the conductive portions 56''' respectively form a group of signals by the distribution of the conductive teeth 562''', from left to right: 11000000, 10001000 , 10000001. In this example, the leftmost digit "1" of each group of signals is preset, that is, the leftmost conductive tooth 562'" of each driver slice 5"' is "informed" that the switch driver 5"' has been placed. The conductive teeth 562"' at other locations are used to change voltage or current.

As described above, the power supply is a power supply or a battery that can be plugged into a power supply socket of an electronic product. Therefore, FIG. 13 illustrates a battery 9 provided with an identification switch. The battery can be used as an external power supply or a backup battery, so there is no need to worry about when the portable electronic products such as notebook computers, PDAs, or mobile phone batteries are lost, damaged, or used in the vicinity of the power supply. The driving piece is inserted into the insertion inlet of the identification switch, and the transmission port 91 as an output port is electrically connected to the electronic product, and the power can be supplied at any time.

However, the above is only the embodiment of the present invention, and the scope of the present invention cannot be limited thereto. That is, the simple equivalent changes and modifications made by the present invention in the scope of the invention and the contents of the invention are still within the scope of the invention.
