이동통신 단말기의 배터리 충전 상태를 표시하기 위한 충전기{Charger for displaying electrification state of battery loaded on mobile phone}Charger for displaying the battery charging status of the mobile terminal {Charger for displaying electrification state of battery loaded on mobile phone}

본 발명은 이동통신 단말기의 배터리 충전 상태를 표시하기 위한 충전기에 관한 것으로서, 특히 이동통신 단말기에 탑재되는 배터리의 충전 상태를 표시할 수 있는 충전기에 관한 것이다.The present invention relates to a charger for displaying a battery charging state of a mobile communication terminal, and more particularly, to a charger capable of displaying a charging state of a battery mounted in a mobile communication terminal.

산업이 발달하고 인간의 활동 영역과 활동 시간이 늘어남에 따라 이를 뒷받침하기 위해 이동통신수단이 혁신적으로 발전을 거듭하고 있으며, 국내의 경우에도 무선통신용 이동전화의 보급이 이미 2천 5백만명을 넘어섰다.As the industry develops and the area of human activity and activity increases, mobile communication means have been innovatively developed, and in Korea, the spread of wireless mobile phones has already exceeded 25 million. .

이와 같은, 무선통신을 위해 사용되는 이동통신 단말기는 이동중에 어느 장소에서나 편리하게 통화나 데이터 전송을 할 수 있는 편리한 통신수단으로 사회의 발전과 함께 널리 사용되고 있으며, 이동전화의 경우 질적 및 양적으로 발전하여 아날로그에서 디지탈방식으로 발전되었다. 이러한, 이동통신 단말기는 개인이 휴대용으로 사용하므로 에너지를 저장해두는 충전식 배터리를 사용하고 있다.As such, the mobile communication terminal used for wireless communication is widely used with the development of society as a convenient communication means that can conveniently call or transmit data at any place during the movement. It has evolved from analog to digital. The mobile communication terminal uses a rechargeable battery that stores energy because it is used by a person.

일반적으로, 이동통신 단말기를 충전하는 충전기는 크게 그 용도에 따라 데스크 탑형 충전기와 여행용 충전기로 분류된다.In general, chargers for charging mobile communication terminals are largely classified into desktop chargers and travel chargers according to their purpose.

데스크 탑형 충전기는 2개의 슬롯을 가지고 있으며, 그 중에 전면 슬롯에는 배터리가 탑재된 이동통신 단말기나 배터리가 장착되고, 다른 후면 슬롯에는 배터리만 장착된다. 즉, 데스크 탑형 충전기는 2개의 배터리를 동시에 충전할 수 있는 장점을 가지고 있다.The desktop charger has two slots, one of which is equipped with a battery-powered mobile terminal or battery in the front slot and the other in the rear slot. In other words, the desktop charger has the advantage of charging two batteries at the same time.

그리고, 여행용 충전기는 이동통신 단말기에 직접 커넥터를 연결하여 충전하거나 데스크 탑 홀더에 커넥터를 연결하여 충전한다. 이러한 여행용 충전기는 휴대를 위해 소형 제작이 가능하도록 하나의 슬롯을 갖고 있다.In addition, the travel charger charges by connecting a connector directly to the mobile communication terminal or by connecting a connector to the desktop holder. These travel chargers have a slot to allow for compact production for portable use.

그러나, 상기한 바와 같은 종래의 충전기의 경우, 배터리의 충전 상태를 표시하여 주고 있지 않기 때문에, 사용자는 배터리의 충전시 이와 같은 정보를 확인하기 위해 이동통신 단말기의 폴더를 직접 열고 이를 확인해야 하는 번거로운 문제점이 있었다.However, in the case of the conventional charger as described above, since it does not indicate the state of charge of the battery, the user has to open the folder of the mobile communication terminal to check such information when the battery is charged. There was a problem.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 이동통신 단말기에 탑재되는 배터리의 충전 상태를 표시하여 사용자가 충전시 배터리의 충전량을 신속히 확인할 수 있도록 하는 충전기를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a charger for displaying a state of charge of a battery mounted in a mobile communication terminal so that a user can quickly check the amount of charge of the battery during charging. have.
