Description

젠더 구조의 USB 충전기Gender Rescue USB Charger
본 발명은 충전기에 관한 것으로, 더욱 상세하게는 가정의 220V 혹은 자동차의 시가 잭을 통해서 충전하는 방법대신 자동차나 컴퓨터의 USB 포트를 통한 젠더구조의 USB충전기에 관한 것이다.The present invention relates to a charger, and more particularly, to a USB charger having a gender structure through a USB port of a car or a computer instead of a charging method through a 220V home or a cigar jack of a car.
현재 아이폰 혹은 스마트폰의 경우 전원 충전을 위하여 자동차내부 시가 잭 방식의 충전기를 이용하는데, 보통 자동차 안에는 하이패스 단말기를 위한 충전기, 내비게이션을 위한 충전기 등, 많은 용도의 시가 잭 방식의 충전기들로 인하여 충전이 여의치가 않은 것이 현실이다. 또한 가정에서는 220V 혹은 110V의 전원을 이용한 어댑터방식의 충전기를 사용하고 있다. 그러나 최근 많은 사람들이 도로에서 시간을 보내거나 전원이 공급되지 않는 곳에서 노트북을 이용하는 경우가 많다. 또한 아이폰의 경우 배터리 교환이 불가능하게 만들어진 관계로 인하여 충전된 양이 부족할 때, 대부분 사람들이 불편함으로 배터리의 즉각적인 충전을 필요로 하고 있다.Currently, the iPhone or smartphone uses a cigar jack charger inside the car to charge the power, but in a car, a charger for a high pass terminal, a charger for navigation, etc. This is not true. In addition, the household uses an adapter type charger using a 220V or 110V power supply. Recently, however, many people spend time on the road or use laptops where there is no power. In addition, the iPhone is not able to replace the battery due to the lack of charge, most people are inconvenient and need to recharge the battery immediately.
이에 첨부된 그림(XX)에서 도시된 바와 같이 자동차나 노트북에는 USB 포트가 존재하지만, 일반 스마트폰의 경우 적은 양의 전류로 충전을 할 수 밖에 없고, 아이폰의 경우는 전혀 충전이 안 되는 경우가 많다. 그 이유는 각각의 스마트폰과 아이폰에서는 충전하기 전에 전원을 공급하는 장치를 보호하기 위해 USB 포트가 일반 데이터통신용 포트인지 USBIF 국제학회에서 정한 충전 ID 프로토콜 방식을 갖고 있는지, 아니면 애플사가 정한 아이폰 고유의 충전 ID 프로토콜 지원 여부에 따라 충전 전류가 차이가 나거나 충전이 전혀 되지 않는다.As shown in the attached figure (XX), there is a USB port in a car or a notebook, but in general, a smartphone can only charge with a small amount of current, and an iPhone can not be charged at all. many. The reason is that in each smartphone and iPhone, the USB port is a general data communication port or a charging ID protocol set by the USBIF International Society to protect the device supplying power before charging, or Apple-specific iPhone The charging current differs or does not charge at all, depending on whether the charging ID protocol is supported.
따라서 본 발명이 이루고자 하는 기술적 과제는 스마트폰 혹은 아이폰을 자동인식하고 그에 따른 충전ID를 출력으로 보내는 반도체 탑재용 회로 및 A타입 플러그와 리셉터클을 일체형으로 구성한 젠더구조의 USB 충전기를 제공하는데 목적이 있다.Accordingly, an object of the present invention is to provide a USB charger having a gender structure in which a circuit for mounting a semiconductor and an A-type plug and a receptacle are integrated with an automatic recognition of a smartphone or an iPhone and a charging ID according to the output. .
상기한 목적을 달성하기 위한 본 발명의 특징은 A타입의 플러그, 리셉터클 그리고 USB 충전 ID를 제공하는 반도체를 탑재하는 기판회로가 일체형으로 구성된다. 플러그에서는 데이터 통신용 핀(pin)인 DP와 DM의 연결을 단절시켜서 탑재 반도체 및 리셉터클의 DP와 DM에 연결되지 않도록 하여 충전ID가 파괴되지 않도록 한다, 단 전원(VBUS)과 접지(GROUND)를 받아서 반도체와 리셉터클의 전원과 접지에 연결해서 충전 ID이 출력이 가능하도록 반도체를 능동모드로 하고, 리셉터클을 통해서 스마트폰에 전류가 흐르도록 한다. 그리고 리셉터클의 4핀(pin)에서는 반도체에서 나오는 DP와 DM, VBUS, GND가 연결되어 스마트폰에 따른 충전 ID를 제공하도록 한다.A feature of the present invention for achieving the above object is an integral type of a circuit board mounted with a type A plug, a receptacle and a semiconductor providing a USB charging ID. The plug disconnects DP and DM, the data communication pins, so that they do not connect to the DP and DM of the onboard semiconductor and receptacle, so that the charging ID is not destroyed. However, the power supply (VBUS) and ground (GROUND) It is connected to the power supply and ground of the semiconductor and receptacle, and the semiconductor is in active mode so that the charging ID can be output. And on the 4 pins of the receptacle, DP, DM, VBUS, and GND from the semiconductor are connected to provide charging ID according to the smartphone.
개개의 플러그와 리셉터클을 접합할 경우, 부러지기 쉬운 단점이 존재하므로 신뢰성 있게 만들기 위하여 일체형인 구조물 즉, 젠더구조의 USB충전기를 제공하며, 그 연결선상에 반도체를 탑재하여 충전이 안 되거나 적은 양의 충전만 이루어지던 기존의 USB 포트로부터 원하는 만큼의 전류를 충전 받도록 할 수 있다.When joining individual plugs and receptacles, there is a disadvantage that breaks easily. Therefore, in order to make it reliable, it provides an integrated structure, that is, a gender USB charger, and a semiconductor is mounted on the connection line to prevent charging or a small amount of charge. You can get as much current as you want from a traditional USB port that only charges.
상기한 바와 같이 본발명의 실시 예에 따른 충전 ID 반도체 탑재된 젠더 구조의 USB 충전기는 충전하고자 하는 스마트폰 혹은 아이폰에 대하여 자동인식 및 각기 다른 충전 ID를 제공함으로써 기존의 USB 포트를 통해서 전원을 충전 받을 수 있다. 즉, 자동차 안의 USB 포트에서 공급되는 전원을 다른 충전기와의 충돌 없이 자동차 안에서 충전할 수 있으며, 전원이 공급되지 않는 곳에서 노트북 USB 포트로부터 가정의 220V 혹은 110V 전원에서 공급받는 것과 같은 양의 충전을 쉽게 받을 수 있다.As described above, a USB charger of a gender structure equipped with a charge ID semiconductor according to an exemplary embodiment of the present invention charges power through an existing USB port by providing automatic recognition and different charging IDs for a smartphone or iPhone to be charged. I can receive it. In other words, the power from the USB port in the car can be charged in the car without clashing with other chargers, and the same amount of charging from the 220V or 110V power source in the home from the USB port of the notebook is not available. You can get it easily.

FIGS. 1 and 2 are exploded perspective views of the present invention.
본 발명인 젠더 구조의 USB 충전기는 A타입 플러그(1) 과, 충전ID 반도체 탑재용 회로(2), A타입 리셉터클(3) 및 이 구성 품들을 보호하는 하우징(11)(12)로 구성된다. 충전ID 반도체 탑재용 회로에는 A타입 플러그에서 전달받는 전원 (4)과 접지(7)와 연결되는 부분과 A타입 리셉터클의 DP, 양의 데이터 시그널 (6)과 DM, 음의 데이터 시그널(5)을 연결되는 부분으로 회로구성을 하였으며 이 회로들은 젠더 구조물 안에 구성된다.The USB charger having a gender structure according to the present invention is composed of an A type plug 1, a charging ID semiconductor mounting circuit 2, an A type receptacle 3, and a housing 11 and 12 for protecting these components. The circuit for charge ID semiconductor mounting includes the part connected to the power source (4) and ground (7) received from the type A plug, the DP of the type A receptacle, the positive data signal (6) and the DM, and the negative data signal (5). The circuit is composed of the parts connected to the circuits, and these circuits are constituted in the gender structure.
기존의 전원 220V에 대한 충전기와 자동차 시가 잭 충전기는 부피도 크지만, 선택의 여지가 부족하며, 안전성에도 문제가 있다. 220V로부터 강압을 하여야 하는 것이므로 저가의 제품에서는 안전성이 많이 의심이 된다. 그러나 본 발명품은 엄격한 검증 하에 만들어져 자동차나 컴퓨터 안에서 5V까지 강압되어서 나오는 충전전류이므로 안전성에 있어서는 월등한 장점을 갖고 있다.The charger for a conventional power supply of 220V and the car cigar jack charger are bulky, but there is a lack of choice and safety problems. Since it is necessary to step down from 220V, there is much doubt about safety in low-cost products. However, the present invention is made under strict verification and has a superior advantage in terms of safety since it is a charging current that is stepped down to 5V in a car or a computer.
본 발명의 충전기를 자동차의 USB포트에 꽂아놓은 경우, 내부에 탑재된 충전 ID반도체는 항상 능동모드에 있으며, 스마트폰이 플러그인 되는 순간 스마트폰의 종류를 인식하여 그에 따른 충전ID를 보내고 나서 1초~2초안에 스마트폰 자체가 원하는 충전 전류로 충전을 시작하게 된다. 컴퓨터의 USB포트에 꽂아놓은 경우 또한 위와 같은 방식으로 충전을 시작하게 된다.When the charger of the present invention is plugged into the car's USB port, the built-in charging ID semiconductor is always in the active mode, and recognizes the type of smartphone at the moment the smartphone is plugged in and sends the corresponding charging ID for 1 second. In 2 seconds, the smartphone itself will start charging with the desired charging current. If you plug it into your computer's USB port, it will start charging the same way.
