Description

전기차 충전기의 충전 플러그{CHARGING PLUG OF ELECTRIC VEHICLE CHARGER}Charging plug of electric vehicle charger {CHARGING PLUG OF ELECTRIC VEHICLE CHARGER}

본 발명은 전기차 충전기의 충전 플러그에 관한 것으로서, 보다 상세하게는 전기자동차의 충전부에 접속되도록 전기차 충전기의 충전케이블에 연결되는 전기차 충전기의 충전 플러그에 관한 것이다.The present invention relates to a charging plug of an electric vehicle charger, and more particularly, to a charging plug of an electric vehicle charger connected to a charging cable of an electric vehicle charger so as to be connected to a charging unit of an electric vehicle.

일반적으로 자동차는 가솔린이나 디젤 등과 같은 화석 연료를 직접 연소하여 사용하는데, 이때 발생하는 유해가스는 대기오염을 일으킬 뿐만 아니라, 지구온난화를 촉진시키는 주범이 되고 있어, 녹색교통 수단의 개발이 신속히 이루어질 필요가 있다.In general, automobiles directly burn fossil fuels such as gasoline or diesel, and the harmful gases generated at this time not only cause air pollution, but also become the main culprit in promoting global warming, so the development of green transportation means needs to be made quickly. There is.

더불어, 가솔린이나 디젤을 만드는 화석연료가 지구상에 얼마 남아있지 않기 때문에, 각 산업분야에서 대체 에너지 개발을 서두르고 있으며, 그 해결책의 일환으로 전기자동차의 보급화를 위한 노력이 진행 중이다.In addition, since fossil fuels that make gasoline or diesel are few on the planet, each industry is in a hurry to develop alternative energy, and as part of that solution, efforts are underway to popularize electric vehicles.

전기자동차는 전기를 동력 공급원으로 하여 운행하는 자동차를 의미하며, 자동차 자체에 전력 공급원으로 충전할 수 있는 배터리를 탑재하고, 탑재된 배터리에서 공급되는 전력을 이용하여 주행한다.An electric vehicle refers to a vehicle that operates with electricity as a power supply source, and a battery that can be charged as a power supply source is mounted in the vehicle itself, and the vehicle runs using power supplied from the mounted battery.

그런데, 전기자동차의 배터리에 전기를 충전하는 것은 각별한 주의가 필요하기 때문에, 전기자동차의 보급 활성화를 위해 다양한 형태로 개발되고 있는 전기자동차 기술의 발전과 더불어, 전기차의 충전기에는 누전, 감전 등의 안전사고를 사전에 미리 예방할 수 있는 구성이 미미하다는 문제가 있었다.However, since charging electricity to the battery of an electric vehicle requires special attention, with the advancement of electric vehicle technology that is being developed in various forms to promote the spread of electric vehicles, electric vehicle chargers have safety such as short circuits and electric shocks. There was a problem that the composition that can prevent accidents in advance is insignificant.

특히, 전기자동차는 충전시간을 단축하기 위하여 급속 충전될 수 있으며, 급속 충전을 위한 전기자동차 충전장치는 완속 충전을 위한 전기자동차 충전장치와 구별될 수 있다.In particular, the electric vehicle can be rapidly charged to shorten the charging time, and the electric vehicle charging device for fast charging can be distinguished from the electric vehicle charging device for slow charging.

급속 충전장치의 경우, 그 구조가 간단하고, 부품의 개수를 최소화하며, 사용자 편의성이 향상되고, 안전 또는 규격상의 요구사항을 만족시킴과 동시에 큰 힘을 요하지 않고 커넥터의 장착 및 탈착이 가능하지만, 충전과정에서 의도하지 않은 상태에서 커넥터가 분리되어 누전이나 스파크에 의한 안전사고가 발생하는 문제점이 있었다.In the case of a quick charging device, the structure is simple, the number of parts is minimized, user convenience is improved, safety or standard requirements are satisfied, and the connector can be mounted and removed without requiring a large force. There is a problem in that the connector is disconnected in an unintended state during the charging process, resulting in a safety accident due to a short circuit or spark.
