Description
본 발명은 핸드폰용 배터리에 관한 것으로, 특히 현재 사용되고 있는 모든종류의 핸드폰 배터리에 적용되어 하나의 충전기에 공용으로 충전할 수 있도록 한 핸드폰용 배터리의 충전접속장치에 관한 것이다.The present invention relates to a battery for a mobile phone, and more particularly, to a charging connection device for a mobile phone battery that can be applied to all kinds of mobile phone batteries currently being used to charge in common to a charger.
일반적으로 핸드폰은 이동성이 좋고, 휴대가 간편하여 보편적으로 사용되고 있으나, 각 제조업체마다 핸드폰의 크기와 형태를 서로 달리하여 제조하고 있으며, 핸드폰 배터리를 충전하는 충전기 또한 제조된 핸드폰 배터리의 형태나 규격에 맞추어 서로 다른 형태로 제조되고 있을 뿐만 아니라, 소비자의 요구에 부합되도록 핸드폰의 기능 향상과 경량화를 추구하려는 경향으로 인하여 동일한 제조업체에서도 다양한 형태의 핸드폰과 이에 맞는 다양한 형태의 핸드폰 충전기가 제조되고 있는 실정이다.In general, mobile phones are widely used because they have good mobility and are easy to carry, but each manufacturer manufactures different sizes and shapes of mobile phones, and chargers for charging mobile phone batteries also conform to the shape or specifications of manufactured mobile phone batteries. In addition to being manufactured in different forms, due to the tendency to improve the functionality and light weight of the mobile phone to meet the needs of consumers, the same manufacturer has been manufacturing various types of mobile phones and various types of mobile phone chargers.
따라서, 종래의 핸드폰 충전기로는 동일 기종에 해당하는 종류의 핸드폰만을 충전시킬 수 있으며, 다른 업체에서 제조된 기종으로 핸드폰을 변경할 경우는 물론이고, 동일한 업체에서 제조된 핸드폰으로 기종을 변경하더라도 핸드폰 배터리의 전극단자와 충전기의 충전단자의 위치가 서로 맞지 않게 되어 핸드폰을 충전할 수 없기 때문에 핸드폰과 충전기를 함께 교체해야 하며, 이에 따라 새로운 모델의 핸드폰을 개발할 경우 이에 맞는 충전기를 더불어 제작해야 하기 때문에 개발비가 추가로 소요되고, 그 개발비를 소비자가 부담하게 되는 악순환이 반복되는 문제점이 있다.Therefore, the conventional mobile phone charger can only charge the type of mobile phone corresponding to the same model, the mobile phone battery even if you change the model to a mobile phone manufactured by the same company, as well as changing the mobile phone to a model manufactured by another company Since the electrode terminals of the charger and the charging terminals of the charger do not match each other, the mobile phone cannot be charged. Therefore, the mobile phone and the charger must be replaced together. There is a problem that the additional cycle, the vicious cycle that the consumer bears the development cost is repeated.
한편, 호텔이나 기타 공공장소에서는 서비스의 일환으로 각종 핸드폰의 충전기를 구비하여 일반 대중에게 핸드폰을 충전할 수 있도록 하고 있다.On the other hand, hotels and other public places are equipped with a charger of various mobile phones as part of the service to allow the public to charge the phone.
그런데, 핸드폰의 종류별로 그에 맞는 별도의 충전기를 사용하여야 하기 때문에 호텔이나 기타 공공장소에 서비스의 차원으로 핸드폰 충전기를 설치하고자 할 경우에는 수시로 변화되는 핸드폰의 기종에 맞추어 여러 가지 형태의 충전기를 비치해야 되므로 설치경비가 과다하게 지출되고, 모든 기종의 충전기를 하나의 장소에 설치하여야 함으로써 설치공간을 확보하는 것이 용이하지 않음으로 인하여 소수의 기종에 맞는 충전기만을 일정 공간에 비치하게 됨으로써 호텔이나 공공장소를 이용하는 모든 사람이 핸드폰을 충전할 수는 없는 문제점이 있었다.However, since a separate charger for each type of mobile phone must be used, when a mobile phone charger is to be installed as a service in a hotel or other public place, various types of chargers must be provided according to the type of mobile phone that changes frequently. Therefore, the installation cost is excessively spent, and it is not easy to secure the installation space by installing all kinds of chargers in one place, so that only a few chargers suitable for a few models are provided in a certain space. There was a problem that not everyone can charge the phone.
본 발명은 이러한 점을 해결하기 위한 것으로, 각기 다른 제조사의 핸드폰인 경우는 물론이고, 동일제조사의 핸드폰임에도 불구하고 고유 모델 번호에 해당하는 핸드폰이 아닌 경우에도 핸드폰의 기종에 상관없이 충전기에 거치시켜 충전할 수 있도록 한 핸드폰용 배터리의 충전접속장치를 제공하는 데 그 목적이 있다.The present invention is to solve this problem, as well as the case of mobile phones of different manufacturers, even if the mobile phone of the same manufacturer, even if the cell phone corresponding to the unique model number, regardless of the type of mobile phone to be mounted on the charger The object of the present invention is to provide a charging connection device for a mobile phone battery that can be charged.

도시된 바와 같이, 본 발명에 적용되는 충전기(10)는 그 일측면에 핸드폰 배터리(20)가 거치되도록 거치면이 형성되고, 이 거치면에는 자력을 발생시키는 복수의 자석(12)이 마련된다. 그리고, 상기 거치면의 하측에는 후술하는 핸드폰 배터리(20)의 전극단자(21)와 도통되도록 충전단자(12)가 마련된다.As shown, the charger 10 applied to the present invention is provided with a mounting surface so that the mobile phone battery 20 is mounted on one side thereof, the mounting surface is provided with a plurality of magnets 12 for generating a magnetic force. In addition, a charging terminal 12 is provided below the mounting surface so as to conduct with the electrode terminal 21 of the mobile phone battery 20 to be described later.
또한, 본 발명에 적용되는 핸드폰 배터리(20)는 통상적으로 제작 및 사용되고 있는 각 제조업체의 다양한 기종을 모두 포함한다.In addition, the mobile phone battery 20 applied to the present invention includes all the various models of each manufacturer that is typically manufactured and used.
이러한 배터리(20)에는 기본적으로 각 핸드폰에 대응되도록 제작된 충전기(10)의 충전단자(12)에 접속되어 배터리(20)를 충전시키기 위한 전극단자(21)가 구비되며, 이러한 전극단자(21)는 통상 배터리(20)의 배면 하단에 위치된다.The battery 20 is basically provided with an electrode terminal 21 for charging the battery 20 is connected to the charging terminal 12 of the charger 10 made to correspond to each mobile phone, such an electrode terminal 21 ) Is usually located at the bottom bottom of the battery 20.
이때, 본 발명에서는 상기 배터리(20)의 배면에 모든 기종의 배터리에 상관없이 충전 가능하도록 하는 충전접속장치(充電接續裝置)(30)가 부착된다.At this time, in the present invention, a charge connection device 30 is attached to the rear surface of the battery 20 so as to be able to charge regardless of batteries of all models.
상기 충전접속장치(30)는 배터리(20)의 배면에 부착되는 소정 두께의 판재(31)와, 이 판재(31)의 배면에 장착되되 상기 충전기(10)의 자석(12)에 대응되어 자화(磁化)되는 자성체(32)와, 상기 판재(31)의 배면에 장착되는 연결단자(33)를 포함하여 구성된다.The charging connection device 30 is mounted on the back plate 31 of the predetermined thickness and the back of the battery 20, and is mounted on the back of the plate 31, the magnet 12 corresponding to the magnet 12 of the charger 10 And a connecting terminal 33 attached to the rear surface of the plate member 31.
상기 판재(31)는 배터리(20)의 배면 형상에 대응 밀착 가능하도록 플렉시블한 재질, 예컨대 합성수지패드 등으로 형성하는 것이 바람직하다.The plate 31 is preferably formed of a flexible material, such as a synthetic resin pad, so as to be in close contact with the back shape of the battery 20.
상기 자성체(32)는 충전기(10)의 거치면에 마련된 자석(12)에 대응 부착되도록 이루어진다. 즉, 본 실시예에서는 상기 충전기(10)의 거치면에 1극성의 자석(12)을 장착하고 판재(31)에는 상기 자석(12)에 대응하여 인력을 발생시킬 수 있도록 자성체(32)가 마련되었지만, 상기 판재에 자석을 장착하고 상기 충전기의 거치면에 자성체를 구비하는 것도 가능하다. 또한, 상기 충전기의 거치면에 1극성의 자석을 장착하고 판재에는 상기 자석과 반대극성의 자석을 장착하는 것 역시 용이하게 실시 가능하다.The magnetic body 32 is made to correspond to the magnet 12 provided on the mounting surface of the charger 10. That is, in the present embodiment, the magnetic material 32 is provided to mount the monopolar magnet 12 on the mounting surface of the charger 10 and to generate the attraction force corresponding to the magnet 12 on the plate 31. It is also possible to mount a magnet on the plate and to have a magnetic material on the mounting surface of the charger. In addition, it is also possible to easily mount a magnet of one polarity on the mounting surface of the charger and a magnet of opposite polarity to the magnet on the plate.
상기 연결단자(33)는 충전기(10)의 충전단자(11)와 배터리(20)의 전극단자(21)를 상호 전기적으로 연결시켜 주는 매개체로서, 이 연결단자(33)는 그 전방으로 연장 인출되는 통전리드(34)에 의해 배터리(20)의 전극단자(21)와 도통하게 된다. 이 때, 상기 판재(31) 및 통전리드(34)는 양면테이프(35)에 의해 배터리(20)의 배면에 안정적으로 부착된다.The connection terminal 33 is a medium for electrically connecting the charging terminal 11 of the charger 10 and the electrode terminal 21 of the battery 20 to each other, and the connection terminal 33 extends outward in front thereof. The conductive lead 34 is used to conduct the electrode terminal 21 of the battery 20. At this time, the plate 31 and the conducting lead 34 is stably attached to the back of the battery 20 by the double-sided tape (35).
따라서, 본 발명에 의한 핸드폰 배터리(20)를 충전하기 위해 배터리(20)를 충전기(10)에 거치할 경우, 사용자가 배터리(20)를 충전기(10)에 대응되도록 위치시키면, 충전기(10)의 자석(12)과 배터리(20)에 부착된 충전접속장치(30)의 자성체(32)의 상호간의 인력에 의해 배터리(20)는 충전기(10)의 거치면에 용이하게 안착되는 것이다. 또한, 상기 자석(12)과 자성체(32)가 인력에 의해 상호 부착될 경우 통전리드(34)에 의해 배터리(20)의 전극단자(21)와 연결된 연결단자(33)는 충전기(10)의 충전단자(11)에 안정적으로 접속된다.Therefore, when the battery 20 is mounted on the charger 10 to charge the mobile phone battery 20 according to the present invention, when the user places the battery 20 to correspond to the charger 10, the charger 10 The battery 20 is easily seated on the mounting surface of the charger 10 by the attraction between the magnet 12 and the magnetic body 32 of the charging connection device 30 attached to the battery 20. In addition, when the magnet 12 and the magnetic body 32 are attached to each other by the attraction force, the connecting terminal 33 connected to the electrode terminal 21 of the battery 20 by the conducting lead 34 is connected to the charger 10 of the charger 10. It is connected to the charging terminal 11 stably.
도 3은 본 발명에 의한 핸드폰용 배터리의 충전접속장치의 다른 실시예를 보인 것으로, 충전접속장치(30)의 연결단자(33)를 배터리(20)의 전극단자(21)에 연결하기 위한 수단으로서 제1실시예에서의 통전리드(34) 대신 탄성체(34')를 장착하되, 이 탄성체(34')는 판재(31)의 전방으로 소정량 돌출되도록 탄지된다.3 shows another embodiment of the charging connection device for a mobile phone battery according to the present invention, and means for connecting the connection terminal 33 of the charging connection device 30 to the electrode terminal 21 of the battery 20. As an example, an elastic body 34 'is mounted in place of the energizing lead 34 in the first embodiment, and the elastic body 34' is supported to protrude a predetermined amount toward the front of the plate 31. As shown in FIG.
즉, 상기 탄성체(34')를 예컨대 도전성 판스프링 등으로 형성함으로써 충전접속장치(30)를 배터리(20)의 배면에 양면테이프(35)로 부착할 경우 탄성체(34')는 그 탄성력에 의해 배터리(20)의 전극단자(21)에 항시 접촉된 상태를 유지하게 되며, 상기 탄성체(34')에 의해 연결단자(33)는 전극단자(21)와 통전되는 것이다.이 때, 본 실시예에서는 배터리(20)의 전극단자(21)와 충전접속장치(30)의 탄성체(34')가 상호 대응되도록 위치되어야 한다는 점이 수반되나, 전극단자(21)와 탄성체(34') 간의 위치가 상호 대응될 경우 탄성체(34')의 탄성력에 의해 전극단자(21)와의 접속은 원활하게 이루어진다는 장점이 있다.That is, when the charging unit 30 is attached to the back surface of the battery 20 with the double-sided tape 35 by forming the elastic body 34 'by, for example, a conductive leaf spring, the elastic body 34' is caused by its elastic force. The electrode terminal 21 of the battery 20 is always kept in contact with the electrode, and the connecting terminal 33 is energized with the electrode terminal 21 by the elastic body 34 '. In this case, the electrode terminal 21 of the battery 20 and the elastic body 34 'of the charging connection device 30 must be located to correspond to each other, but the position between the electrode terminal 21 and the elastic body 34' In this case, the connection with the electrode terminal 21 is made smooth by the elastic force of the elastic body 34 '.
한편, 본 실시예에서는 핸드폰 배터리와 이 배터리를 충전시킬 수 있는 충전기를 일예로 설명하였으나, 본 발명에 따른 충전접속장치는 전기적 연결 및 분리가 잦은 모든 장치 간의 접속단자에 사용될 수 있다. 예컨대, 핸드폰의 스피커 출력단자 및 마이크로폰 입력단자를 핸드폰의 배면을 통해 배터리의 배면까지 연장하고, 배터리 배면에 충전단자와 별도의 스피커 출력단자 및 마이크로폰 입력단자를 형성한 후, 이에 대응하여 핸즈프리(hands free)의 상면에 핸즈프리 스피커 입력단자 및 핸즈프리 마이크로폰 출력단자를 구비하면, 핸드폰과 핸즈프리 간의 음성신호 접속단자 간의 전기적 접속에도 본 발명이 적용될 수 있는 것이다.On the other hand, in the present embodiment has been described as a mobile phone battery and a charger that can charge the battery as an example, the charging connection device according to the present invention can be used in the connection terminal between all the frequent electrical connection and disconnection. For example, the speaker output terminal and the microphone input terminal of the mobile phone are extended to the back of the battery through the back of the mobile phone, and a speaker output terminal and a microphone output terminal separate from the charging terminal are formed on the back of the battery, When the hands-free speaker input terminal and the hands-free microphone output terminal are provided on the upper surface of the free), the present invention can be applied to the electrical connection between the voice signal connection terminal between the cellular phone and the hands-free.
이상에서 설명한 바와 같이, 본 발명에 의하면 각기 다른 제조업체의 핸드폰은 물론이고, 동일제조업체의 핸드폰임에도 불구하고 고유 모델 번호에 해당하는 핸드폰이 아닌 경우에도 핸드폰의 기종에 상관없이 충전기에 거치시켜 충전할 수 있게 된다.As described above, according to the present invention, even if the cell phone of the different manufacturers, as well as the cell phone of the same manufacturer, even if the cell phone corresponding to the unique model number can be charged to the charger regardless of the model of the cell phone Will be.
