Description

전기자동차용 충전플러그Charging plug for electric vehicle

본 발명은 전기자동차용 충전플러그에 관한 것으로, 특히 충전플러그 자체에서 충전상태와 금액을 표시해 줄 수 있게 되고, 손으로 잡기 편리한 형태로 되어 충전작업이 매우 용이하게 이루어질 수 있도록 된 전기자동차용 충전플러그에 관한 것이다.The present invention relates to a charging plug for an electric vehicle, and in particular, it is possible to display the state of charge and the amount of charge in the charging plug itself, and the charging plug for an electric vehicle that can be made very easy to charge by a convenient form to hold by hand. It is about.

일반적으로 전기자동차는 1회 충전으로 주행할 수 있는 거리가 오일에 의해 주행하는 자동차에 비해 매우 짧으므로 그 만큼 충전을 자주 해 주어야만 한다.In general, the electric vehicle can be driven by a single charge is very short compared to the vehicle driven by oil, so the charge should be frequently frequented.

따라서, 충전작업을 얼마나 편리하게 행할 수 있느냐는 자동차의 상품성과도 직결되는 중요한 문제라 할 수 있겠다.Therefore, how convenient it is to perform the charging operation can be said to be an important problem directly connected to the merchandise performance of the car.

한편, 전기자동차의 충전은 도 3에 도시된 바와 같이 충전소에 구비된 충전기(11)에 케이블(12)을 매개로 연결된 충전플러그(13)를 자동차의 측부 또는 전/후방부에 설치되어 있는 소켓에 삽입하여 양자간의 단자를 연결시킴으로써 충전기(1)로부터 전기를 자동차의 충전배터리로 공급함으로써 이루어지도록 되어있으며, 종래 전기자동차용 충전플러그(13)는 도 4에 도시된 바와 같이 케이블(12)에 플러그케이스(13a)가 직접 연결되고, 이 플러그케이스(13a)내에 구비된 2개의 충전단자(13b)에 상기 케이블(12)로부터 인출된 전선(12a)가 연결되는 구조로 되어 있었다.On the other hand, the charging of the electric vehicle, as shown in Figure 3, the socket 11 is provided with a charging plug 13 connected to the charger 11 provided in the charging station via the cable 12 via the side of the vehicle or the front / rear It is made by supplying the electricity from the charger 1 to the charging battery of the vehicle by connecting the terminals between the two, and the conventional electric vehicle charging plug 13 is connected to the cable 12 as shown in FIG. The plug case 13a was directly connected, and the electric wire 12a drawn out from the cable 12 was connected to the two charging terminals 13b provided in the plug case 13a.

또한, 상기 충전플러그(13)가 삽입되는 종래의 소켓(14)은 케이블(16)에 소켓케이스(14)가 직접 연결되고, 이 소켓케이스(14)의 내에는 상기 플러그케이스(13a)가 수용될 수 있는 수용홈(14a)가 형성되며, 이 수용홈(14a)의 사이에 상기 충전플러그(13)의 충전단자(13b)가 삽입되면서 접촉되는 수용단자(15)가 구비되며, 이 수용단자(15)는 상기 케이블(16)에 인출된 전선(16a)과 연결되는 구조로 되어 있다.In the conventional socket 14 into which the charging plug 13 is inserted, a socket case 14 is directly connected to a cable 16, and the plug case 13a is accommodated in the socket case 14. The receiving groove 14a may be formed, and the receiving terminal 15 is provided between the receiving grooves 14a to be contacted while the charging terminal 13b of the charging plug 13 is inserted therein. 15 is structured to be connected to the electric wire 16a drawn out to the said cable 16. As shown in FIG.

따라서, 상기 플러그케이블(13a)가 수용홈(14a)에 안착되도록 충전플러그(13)를 소켓(14)에 끼우면, 이때 상기 충전단자(13b)가 소켓(14)의 수용단자(15)에 접속되어 전기가 흐를 수 있게 됨으로써 충전작업이 이루어지게 된다.Therefore, when the plug plug 13 is inserted into the socket 14 so that the plug cable 13a is seated in the receiving groove 14a, the charging terminal 13b is connected to the receiving terminal 15 of the socket 14. As the electricity can flow, the charging operation is performed.

그러나, 상기 충전플러그(13)는 그 크기나 형태가 직접 손으로 잡고 충전작업을 행하기가 다소 불편하였고, 또한 충전작업 도중 충전상황이나 요금상황을 알아보기 위해서는 고개를 돌려 충전기에 표시되는 수치를 읽어야 했으므로 이 또한 불편한 점이 아닐 수 없었다.However, the charging plug 13 was somewhat inconvenient to carry out the charging operation by holding the size or shape of the hand by hand, and in order to find out the charging status or the charging status during the charging operation, the numerical value displayed on the charger was turned. This was also inconvenient because it had to be read.

이에 본 발명은 상기와 같은 불편함을 해소하기 위해 안출된 것으로, 충전플러그의 형태를 손으로 잡기 쉬운 형태로 개선하고, 충전플러그 자체에 충전상황이나 금액을 표시해줄 수 있도록 함으로서 충전작업을 보다 손쉽게 행할 수 있도록 한 전기자동차용 충전플러그를 제공함에 그 목적이 있다.Accordingly, the present invention has been devised to solve the above inconvenience, improve the shape of the charging plug into a form that is easy to grasp by hand, and to make the charging work more easily by displaying the charging status or the amount on the charging plug itself. It is an object of the present invention to provide a charging plug for an electric vehicle.
