Description

Mobile phone charger with battery and nickel plated magnets {Battery and nickel plating magnet used seperation type mobile phone charger}

The present invention relates to a detachable mobile phone charger using a battery and a nickel-plated magnet, and more specifically, using a connection connector and combining a charger for supplying general battery power through an external power connection port of a mobile phone by a magnetic force of a magnet. And detachable housing in multiple stages so that it can be detached as needed. Small and light, so that it can be attached and detached as needed. The present invention relates to a detachable mobile phone charger using a battery and nickel-plated magnet that can be easily used.

As is well known, as a mobile communication terminal that can carry and communicate while being carried, users are increasing day by day because they can be used and are convenient to carry and store without being restricted by time and space. You can listen to music in the form or connect to the Internet and receive information in real time. Recently, various functions, such as video information, are added to increase the talk time and standby time. Although a rechargeable battery is required, its development is delayed due to technical limitations, and thus there is a problem in that it needs to be frequently charged when discharged with a small capacity rechargeable battery.

Due to the above problems, mobile phone users always carry large and heavy separate mobile phone chargers while charging at home or office, or using battery chargers such as cigarette lighter jacks in vehicles or charging chargers that differ by manufacturer. Possible universal mobile phone fast charger is a cumbersome and inconvenient problem because it must be charged using a limited charging place installed in large quantities.

In order to solve the above problems, as a primary battery, a device for charging a discharged mobile phone battery using a DC power source of a general battery which can be easily purchased on the market, the Republic of Korea Patent Office (KR) Registered Utility Model Publication (Y1) Power supply device "(notice date: 2000.7.15) describes a mobile phone charging device with a connection connector connected by a cable to connect to a connection port of a mobile phone in a case in which a voltage stabilization circuit is built in and a common battery compartment is provided. (KR) Registered Utility Model Bulletin (Y1) "Auxiliary battery pack for power supply of mobile communication terminal" (Notice date: 2002.2.9) can be easily obtained when the battery is discharged without the charger to charge the battery attached to the mobile terminal. Attach the battery pack containing the power supply medium (battery, solar cell, etc.) to the back of the mobile communication terminal A secondary battery for power supply of a mobile communication terminal is provided for supplying power through a battery. Both of the advantages of using a DC power source of a commercially available battery can be quickly charged and used when a cell phone battery is discharged. However, there is a problem in that the body housing is integral and large and heavy compared to a mobile phone which is miniaturized and light weight as a single body, which is inferior in practicality or decorativeness.

In addition, the charging of such a battery can be obtained by applying electrons to the negative electrode of the battery. Usually, a DC component controlled by a constant voltage is applied to charge the battery by supplying electrons due to the difference of the applied voltage and the battery internal voltage. The applied voltage is determined per unit cell (C). Normally, lithium ion batteries and lithium polymer batteries for mobile phones should be applied with a constant voltage of 3.6V per cell and strictly limited to 4.2V. When the gas is decomposed and the pressure-opening valve is operated, leakage occurs and if there is a danger of explosion, the rated voltage must be maintained and the charging current must be limited to maintain the specified current to maintain the battery of the phone.

The present invention has been made in order to achieve the above object, the charger case does not require a separate battery storage space, the upper head portion with a nickel-plated magnet and the intermediate body equipped with a boost converter circuit, the lower connector provided with a connection jack It is formed by three-stage detachable type, and each component is assembled and integrated by magnetic force in the usual time, and it is separated when charging.The battery is placed between the upper head and the middle body, and the connecting jack of the connector part is provided in the mobile phone. It is intended to provide a detachable mobile phone charger using a battery and a nickel-plated magnet, which enhances the convenience of carrying and storage by being attached to and detachable from the user.

Intermediate body portion 20 is equipped with a substrate with a built-in converter circuit 23 is connected to the upper head portion 10 and the corrugated fixing line 13, the lower connection jack is connected to the mobile phone connection port 51 Three stages of the connector portion 30, which is provided with a 31 and electrically connected to the converter circuit 22 by an electric wire 32 To form a de-removable,

Reference numeral 50 is a mobile phone.

The first aspect of the present invention is to improve the problem that the battery charger for charging a mobile phone using a DC power supply of a conventional battery does not correspond to a mobile phone which is becoming smaller and lighter, and occupies the space of the battery compartment, thereby becoming bulky. By using the magnetic force of the magnet and forming a casing in three stages, the housing can be detached and detached without a separate locking device if necessary, so that the battery can be fixedly stored by the magnet attraction. 30 is simply pushed into the intermediate body 20 is simply coupled by the elastic force of the spring.

That is, the upper head portion 10 of the present invention is a plate-shaped nickel-plated magnet 12 that sucks the magnetic material is embedded in the middle and one end of the recess groove (12a) (12b) and the positive and negative terminals of the battery 40 In contact with each other, the intermediate body portion 20 also contacts the positive and negative electrodes of the battery 40 individually by contacting the catching grooves 21a and 22a of the nickel plated magnets 21 and 22, and is connected to the lower IC substrate. Power is supplied to the boost converter circuit 23 located therein to extract the rated voltage of 4.2V and the current of 500 mA by the operation of the converter circuit 23, and the connector portion 30 is freely crimped in length extension in the form of an elastic spring. The connection jack 31 having the wire 32 attached thereto is connected to the external connection port 51 of the mobile phone. The magnet is plated with nickel having good conductivity, so that the plate is adhered closely and the corrosion resistance is improved.
