Description

Electric power supply apparatus for portable electric device capable of substitute it's storage battery}

The present invention relates to a power supply that can be used as a battery substitute for portable electronic devices. More specifically, in various portable electronic devices such as mobile phones, PDAs (Personal Digital Assistants), digital cameras, digital camcorders, etc., each dedicated battery is used to replace each dedicated battery using commercially available batteries. The present invention relates to a battery substitute power supply of a portable electronic device capable of supplying driving power to the portable electronic device.

Recently, thanks to the rapid development of wired / wireless communication technology and high density integration technology of various electronic devices, mobile phones, PDAs (Personal Digital Assistants), digital cameras, digital camcorders, etc., which are convenient to carry and use large amounts of information Various portable electronic devices are widely used.

In addition, various portable electronic devices are generally driven by rechargeable rechargeable batteries. These dedicated batteries are essential parts of portable electronic devices, and are usually used as separate chargers using 110V or 220V commercial voltages supplied to homes or businesses. It is often recharged.

When the battery is exhausted without a spare battery, there is no countermeasure other than recharging using a charger, which is only possible when electricity is supplied. Although the driving power can be directly supplied through an adapter having a converter function depending on the type of portable electronic device, this is also limited to a specific place where electricity is supplied such as a vehicle or a home.

Therefore, when the battery is exhausted in places where electricity cannot be supplied, such as in the mountains or outdoors, a big failure can be seen.In contrast, the battery of portable electronic devices can be recharged using batteries that can be easily obtained from the surroundings. Several simple chargers have been introduced.

1 is a perspective view of the 'charging device for replacing and charging the battery of the mobile phone' introduced in the Republic of Korea Utility Model Registration No. 0253479 as an example, briefly summarized, the main body that the built-in converter circuit and the battery is stored ( 30) and a spring-shaped wire 20 extending to the outside of the DC power source of the battery and the socket connector of the mobile phone 1, which is attached to the end of the wire 20, is called a carkit connector. A plug connector 10 is included.

Similarly, Korean Utility Model Registration Publications 0210704, 211542, 0278387, 0314202, 0314667, 0314668, 0314669, etc., introduced a variety of simple chargers for mobile phones. The plug connector 10 fitted into the socket connector of the mobile phone 1 is adopted as a common component.

Therefore, the range of their use is limited to the mobile phone 1 equipped with the socket connector, and since the plug connector 10, which is a relatively precise component, is an essential component, the manufacturing cost and the selling price are high, and the possibility of failure and malfunction is high. It is difficult to be widely used as a response to rare emergencies such as travel.

In particular, considering that the socket connector of the existing mobile phone 1 is different by manufacturer and model, the above-mentioned simple charger for a mobile phone has a fatal disadvantage that it can be applied to only a limited number of models. It is equipped with a complex configuration has a disadvantage in that it is inconvenient to move and carry in the state connected to the mobile phone 1 because of its large volume.

Furthermore, even a small impact is often observed that the plug connector 10 and the socket connector of the mobile phone (1) is detached, and as a result of this inconvenience as well as to break the socket connector of the mobile phone (1).

On the other hand, although the battery used in various portable electronic devices including the mobile phone 1 can be recharged, there is no limit to the lifespan. This is greatly reduced and the amount of exhaustion is so large that it can be used only for a short time. However, most conventional simple chargers indirectly supply driving power to the mobile phone 1 by recharging the battery of the mobile phone 1, so when the battery is old, it is difficult to expect a very useful utility.

Accordingly, the present invention has been made to solve the above problems, and can be applied to all kinds of portable electronic devices as well as mobile phones, and has a relatively simple configuration while using a battery that can be easily obtained in the vicinity. The purpose of the present invention is to provide a battery substitute power supply for portable electronic devices that can be produced and sold, and in particular, can maintain a stable and intimate connection state.

2 and 3, a flexible printed circuit 130 drawn out from the (+) (-) output terminal 120 of the main body 110 to the outside is commonly used. A signal line made of a plurality of conductive metals is embedded therein and a FPC film rich in ductility is coated therein.

One end 130a of the flexible printed circuit board 130 is connected to the (+) and (-) output terminals 120 and the other end is divided into two branches, respectively (+) of the main body 110 battery group 100. When the (-) voltage is drawn out, the reason for using the flexible circuit board 130 in the present invention is to enable a flexible response despite the movement of the main body 110 and the portable electronic device. This is described in more detail in that section.

Next, the other end 130b of the flexible printed circuit board 130 is connected and fixed to the positive and negative connection terminals of the portable electronic device through a predetermined adhesive member 140. FIG. As a partial exploded perspective view showing an enlarged portion A, the adhesive member 140 is a view for explaining.

As shown, the adhesive member 140 according to the present invention may be any type of adhesive pad 142a coated on at least one surface and made of an insulating material, and these adhesive pads 142a may be a pair having a predetermined size. It is provided as to cover the other end 130b of the flexible printed circuit board 130, respectively.

At this time, the other end (130b) of the flexible circuit board 130 is exposed to the signal line (S) for outputting the (+), (-) voltage of the battery group 100 of the main body 110, respectively, a pair of The adhesive pads 142a cover these signal lines S, respectively, and apply pressure to contact and fix them with (+) and (-) connection terminals of portable electronic devices described later.

Therefore, the other end 130b of the flexible printed circuit board 130 is tightly fixed in the state of being electrically connected with the (+) and (-) connection terminals of the portable electronic device, respectively. In the drawing, reference numeral 144 denotes a protective cover such as vinyl covering the adhesive surface of the adhesive pad 142a. When the adhesive material is coated on both surfaces of the adhesive pad 142a, the protective cover 144 is It may be attached to both sides thereof, which is the part removed when using the power supply according to the invention.

Meanwhile, the adhesive member 140 may be deformed as long as it can electrically connect and fix the other end 130b of the flexible circuit board 130 to the (+) and (-) connection terminals of the portable electronic device, respectively. 5 is a partial exploded view showing another example thereof.

In the above drawings, an anisotropic conductive film (ACF) pad 142b is used as the adhesive member 140, which, as is well known, contains conductive particles dispersed in an adhesive insulating material. Enable electrical connection.

Therefore, the pair of anisotropic conductive film pads 142b are interposed between the other end 130b of the flexible circuit board 130 and the (+) and (-) connection terminals of the portable electronic device, respectively, and the other end of the flexible circuit board 130. The signal lines S exposed to the 130b and drawn out the positive and negative voltages of the battery group 100 are closely adhered to the positive and negative connection terminals of the portable electronic device. Can be connected.

In addition, the reference numeral 144 denotes a vinyl cover which can be attached to the front and back surfaces thereof to protect the anisotropic conductive film pad 142b as described above, and is also removed when used, and FIGS. 4 and 5 also play the same role. The same reference numerals are used to designate the same parts, and thus redundant descriptions are omitted.

Hereinafter, a method of using the power supply apparatus according to the present invention will be described with reference to FIGS. 6 and 2 to 5.

6 is an exploded perspective view showing a case in which the power supply device according to the present invention is connected to the mobile phone 1, and as shown, all types of mobile phones 1 are biased toward the bottom of the rear side (+) and (-) connection terminals. (5) is provided. In addition, the dedicated battery 3 is provided with corresponding (+) and (-) output terminals 3a as corresponding parts, respectively, so that the dedicated battery 3 is bound and used in the rear direction of the mobile phone 1.

In this case, when all the dedicated batteries 3 are exhausted, the power supply device according to the present invention is used for emergency purposes. First, the battery 3 is separated from the mobile phone 1, and then the flexibility of the power supply device according to the present invention. The protective cover 144 attached to the other end 130b of the circuit board 130 is peeled off and connected to the (+) and (-) connection terminals 5 of the mobile phone 1, respectively.

For reference, in addition to the above (+) and (-) connection terminals 5, the general mobile phone 1 may include various terminals 6 of the same type. 5) The other end 130b of the flexible circuit board 130 may be connected to each other, but if it is not, inquire to a place that provides a mobile phone charging service such as a convenience store, it is easy to distinguish the (+) and (-) connection terminals (5). I can do it.

Therefore, the adhesive line 142a and the signal line S of the other end 130b of the flexible printed circuit board 130 are sequentially positioned from the (+) and (-) output terminals 3a of the battery 3, and then the battery 3 By binding), the flexible circuit board 130 is naturally connected and fixed by the (+) (-) connection terminal 5 of the mobile phone 1.

In addition, in this case, when the signal line S at the other end of the flexible circuit board 130 is not arranged, it may be contacted with the other terminal 6 which is unnecessary, although not shown in the drawing, preferably, A separate vinyl cover or the like having a hole for opening the corresponding part may be interposed so that only the (+) (-) connection terminal 5 of (1) can be connected.

In addition, as mentioned earlier, three AAA size 1.5V batteries may be included in the main body, and thus, the other end 130b of the flexible circuit board 130 may have 4.5V corresponding to the output voltage of the battery 3, respectively. Since DC power is output, the mobile phone 1 can be used stably despite the exhaustion of the dedicated battery 3.

7 is a partial perspective view illustrating a connection state of another portable electronic device except for a mobile phone and a power supply device according to the present invention, wherein the portable electronic device includes a battery storage unit 7 in which a dedicated battery can be stored. Here, (+) and (-) connection terminals 5 are exposed in the form of springs and protruding pieces, respectively.

Therefore, each of the corresponding connection terminal 5 is used to bond the other end 130b of the flexible circuit board 130 of the power supply according to the present invention, in this case, the adhesive member 140 is coated with an adhesive material on one surface It is preferable that the adhesive pads. Accordingly, the other end of the flexible printed circuit board may be covered and fixed to be in contact with the (+) and (-) connection terminals, respectively.

In addition, the power supply device according to the present invention as described above may be interposed with a coupling medium such as Velcro tape or double-sided adhesive tape to one side of the main body 1 for more convenient use, by attaching to a portable electronic device using the same It can be stably used by those skilled in the art, and reference numeral 110a of FIGS. 2 and 3 indicates these bonding media.

The power supply apparatus according to the present invention uses a method of physically contacting the other end of the flexible circuit board to the (+), (-) connection terminal of the portable electronic device as a method of connecting the portable electronic device, Since it does not require a separate connecting part such as a plug connector, it can be used universally for mobile phones and all kinds of portable electronic devices.

In addition, the other end of the flexible printed circuit board can be electrically connected with (+) and (-) connection terminals through an adhesive member, as well as tightly fixed, and thus has a simple and convenient configuration with less chance of failure or malfunction. The advantage is that the price can be lower. Therefore, it can be used critically in emergency such as hiking or traveling where the use of charger is impossible.

In particular, the present invention has the advantage that there is no limitation by manufacturers, models of all kinds of portable electronic devices, including mobile phones, there is a disadvantage that the volume is easy to carry and convenient to use. In addition, when applied to a mobile phone, for example, the other end of the flexible circuit board and the (+), (-) connection terminal of the power supply according to the present invention after fixing the battery to the upper part of the close contact with the external impact. There is an advantage to maintain.

In addition, since the power supply device according to the present invention does not use a port (for example, a USB port) of the portable electronic device, the portable electronic device can be freely connected to an external device using the port while using the device. This can be particularly beneficial in some cases, such as when working on a PC for download.
