Description

전기자동차 충전용 컨넥터의 결합구조{COMBINATION STRUCTURE OF CONNECTOR FOR CHARGING ELECTRIC VEHICLE}CONNECTION STRUCTURE OF ELECTRIC VEHICLE CONNECTOR {COMBINATION STRUCTURE OF CONNECTOR FOR CHARGING ELECTRIC VEHICLE}

본 발명은 전기자동차 충전기용 컨넥터의 결합구조에 관한 것으로서, 보다 구체적으로는 전기자동차 충전기용 컨넥터를 사용하지 않을 때에 홀더에 적절하게 지지하여 부주의로 떨어뜨리거나 이탈되지 않도록 하는 전기자동차 충전기용 컨넥터의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a connector for an electric vehicle charger, and more specifically, to a connector for an electric vehicle charger that is appropriately supported in a holder when the electric vehicle charger connector is not in use to prevent it from being inadvertently dropped or deviated. It relates to a coupling structure.

최근, 지구 환경 문제의 관점에서 화석연료를 이용하지 않는 전기 자동차가 주목되어 있다. 전기 자동차는 구동용 배터리를 탑재하고 배터리에 충전된 전기에 의해 주행할 수 있다.Recently, electric vehicles that do not use fossil fuels have been noted in view of global environmental problems. The electric vehicle is equipped with a driving battery and can be driven by electricity charged in the battery.

전기 자동차에 대해서 충전을 하기 위해서는 차량 탑재 측의 수전 커넥터와 이것에 적합한 전원 측의 전원 공급 커넥터가 필요하다. 또한 정전 시에는 자동차에 수전된 전기를 이용하여 가정용 전원으로 하는 것도 가능하다. 이 경우에도 자동차 측에서 수전하는 수전 커넥터가 필요하다. 이들의 커넥터는 전기 자동차를 대상으로 사용 편의성이나 안전성 등을 고려한 설계가 이루어져 있고 종래부터 전력선으로 이용되고 있는 커넥터와는 다른 형태를 가지고 있는 것이 일반적이다.In order to charge the electric vehicle, a power receiving connector on the vehicle-side side and a power supply connector on the power side suitable for this are required. Also, in the event of a power failure, it is possible to use electricity received in a vehicle as a household power source. Even in this case, a power receiving connector for receiving power from the vehicle side is required. These connectors are designed for ease of use, safety, etc. for electric vehicles, and generally have a different form from the connectors used in power lines.

이러한 전기 자동차용 전원 공급 커넥터로서는 예를 들어 케이스와 이 케이스로 슬라이드 가능하게 장착되어 복수의 단자를 수용한 커넥터 본체와 커넥터 본체와 동축 방향으로 슬라이드 가능하게 장착하는 파이프형 핸들과 레버를 구비하고, 레버의 회동에 의해 핸들이 전진해 커넥터 본체를 상기 수전 측 커넥터의 커넥터 본체와 끼워맞추는 전원 공급 커넥터가 있다.Examples of the power supply connector for an electric vehicle include, for example, a case and a connector body that is slidably mounted in the case and accommodates a plurality of terminals, and a pipe-shaped handle and a lever that are slidably mounted in a coaxial direction with the connector body, There is a power supply connector that moves the handle by the rotation of the lever and fits the connector body to the connector body of the power receiving side connector.

한편, 이러한 전기 자동차의 충전기용 커넥터에는 충전 중 통전하고 있는 상태의 전원 공급 커넥터를 수전 커넥터에서 분리하는 것을 방지하는, 잠금 기구가 마련되어 있다. 이 잠금 기구가 없으면 통전하고 있는 상태에서 전원 공급 커넥터가 수전 커넥터에서 분리해지고 분리한 순간에 아크가 발생하는 위험이 있다.On the other hand, such a connector for a charger for an electric vehicle is provided with a locking mechanism that prevents the power supply connector in the energized state from being disconnected from the power receiving connector during charging. Without this locking mechanism, the power supply connector is disconnected from the power receiving connector while energized, and there is a risk of arcing at the moment of disconnection.

이러한 잠금 기구로서는 예를 들면 전원 공급 커넥터 측에 마련된 래치(핀 형상 포함)을 수전 커넥터 측의 걸림부에 걸리게 하는 방법이 있다. 통전중은 이 잠금 기구가 해제되지 않도록 함으로써, 통전중에 전원 공급 커넥터가 수전 커넥터에서 분리해지는 것을 방지할 수 있다.As such a locking mechanism, for example, there is a method of engaging a latch (including a pin shape) provided on the power supply connector side with a locking portion on the power receiving connector side. By preventing this locking mechanism from being released during energization, it is possible to prevent the power supply connector from being disconnected from the power receiving connector during energization.

그러나 이러한 전원 공급 커넥터는 사용 시 이외에는 충전 장치 등에 재치되거나 후크 등에 걸 수 있어 지지되어 있다.However, such a power supply connector is supported because it can be mounted on a charging device or hooked to a hook or the like except for use.

이 때문에 케이블을 발에 거는 등 했을 경우에 커넥터가 낙하해 케이스나 전술한 래치나 단자부 등이 파손할 우려가 있다. 또한 사용자 이외의 사람이 용이하게 커넥터를 손에 들 수 있기 때문에, 장난 등에 의해 파손의 우려도 있다.For this reason, when the cable is hung on the foot or the like, the connector may fall, and the case, the latch and the terminal portion described above may be damaged. In addition, since the connector can be easily held by a person other than the user, there is a risk of damage due to mischief.

이하, 본 발명에 따른 전기자동차 충전기용 컨넥터의 결합구조의 동작에 대하여 상세히 설명한다.Hereinafter, the operation of the coupling structure of the connector for an electric vehicle charger according to the present invention will be described in detail.

사용자가 전기자동차의 충전을 위하여, 컨넥터(10)를 충전기(1)로부터 분리하고자 할 때, 사용자는 약간의 힘을 주어 컨넥터(10)의 손잡이를 잡아당기면 된다.When the user wants to disconnect the connector 10 from the charger 1 for charging the electric vehicle, the user needs to pull the handle of the connector 10 with little force.

그러면, 컨넥터(10)의 잠금홈(15)에 지지되어 있던 제 1전방회동편(31)의 제 1잠금핀(37)과 제 2전방회동편(131)의 제 2잠금핀(137)이 라운드 형태로 되어 있기 때문에 자연스럽게 상기 잠금홈(15)으로부터 분리되게 되고, 상기 제 1전방회동편(31)과 제 2전방회동편(131)은 외측으로 벌어지게 된다. 이와 함께, 상기 제 1힌지축(35)과 제 2힌지축(135)를 중심으로 상기 제 1후방경사편(33)과 제 2후방경사편(133)이 내측으로 좁혀지게 된다. 이때, 상기 제 1판스프링(40)과 제 2판스프링(140)이 그 본래의 복원력에 의해 제 1후방경사편(33)과 제 2후방경사편(133)을 내측방향으로 더 밀게 되고, 제 1힌지축과 제 2힌지축을 중심으로 상기 제 1전방회동편(31)과 제 2전방회동편(131)이 외측으로 더 벌어지면서, 상기 컨넥터(10)를 충전기로부터 분리할 수 있는 것이다.Then, the first locking pin 37 of the first front pivoting piece 31 and the second locking pin 137 of the second forward pivoting piece 131 supported by the locking groove 15 of the connector 10 are Since it is in a round shape, it is naturally separated from the locking groove 15, and the first front pivoting piece 31 and the second front pivoting piece 131 are opened outward. At the same time, the first rear inclined piece 33 and the second rear inclined piece 133 are narrowed inwards around the first hinge axis 35 and the second hinge axis 135. At this time, the first plate spring 40 and the second plate spring 140 pushes the first rear inclined piece 33 and the second rear inclined piece 133 further inward by its original restoring force, The first front pivoting piece 31 and the second front pivoting piece 131 are further spread outward around the first hinge axis and the second hinge axis, so that the connector 10 can be separated from the charger.

반대로, 사용자가 충전기를 사용하고 홀더(20)에 거치시키기 위해서, 컨넥터(10)를 홀더(20)에 삽입하게 되면, 상기 컨넥터부(11)가 내측삽입부(27)에 삽입될 때 쯤, 상기 케이스(13)의 선단부가 상기 제 1후방경사편(33)과 제 2후방경사편(133)을 밀고 들어가게 된다. 그러면, 상기 제 1힌지축과 제 2힌지축을 중심으로 상기 제 1전방회동편(31)과 제 2전방회동편(131)이 내측으로 좁혀지면서 상기 제 1잠금핀(37)과 제 2잠금핀(137)이 상기 잠금홈(15)에 삽입되면서, 상기 컨넥터(10)가 상기 홀더(20)에 안정적으로 안착될 수 있는 것이다.Conversely, when the user uses the charger and the connector 10 is inserted into the holder 20 in order to be mounted on the holder 20, when the connector portion 11 is inserted into the inner insertion portion 27, The front end of the case 13 is pushed into the first rear inclined piece 33 and the second rear inclined piece 133. Then, the first locking pin 37 and the second locking pin while the first forward pivoting piece 31 and the second forward pivoting piece 131 are narrowed inward about the first hinge axis and the second hinge axis. As the 137 is inserted into the locking groove 15, the connector 10 can be stably seated on the holder 20.

이상에서 본 발명의 바람직한 실시예에 대하여 상세하게 설명하였지만 본 발명의 권리범위는 이에 한정되는 것은 아니고 다음의 청구범위에서 정의하고 있는 본 발명의 기본 개념을 이용한 당업자의 여러 변형 및 개량 형태 또한 본 발명의 권리범위에 속하는 것이다.Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concept of the present invention defined in the following claims are also provided.
