    • An electromagnetic coupling device for charging an electric motor vehicle is provided which is easy for handling a charging coupler and hardly lowers electric power transmission efficiency for a long period of time. A charging coupler (10) containing a primary coil (15) is provided with a pair of heat-shielding covers (16), which are pivotably mounted on the coupler (10) by pins (17). When the charging coupler (10) is inserted into a depression (31) in an incoming unit of the electric motor vehicle, guides (21) push lower ends (16a) of the covers (16) to open the covers (16). The primary coil (15) in the charging coupler (10) is electromagnetically coupled to a pair of secondary coils (32, 32) in the depression (31). After charging, when the charging coupler (10) is drawn out of the depression (31), the heat-shielding covers (16) are closed by tension coil springs (18), thereby protecting the primary coil (15) and preventing a person from carelessly touching it.
    • 提供一种用于对电动车辆充电的电磁耦合装置,其容易处理充电耦合器并且几乎不降低电力传输效率长时间。 包含初级线圈(15)的充电耦合器(10)设置有一对隔热罩(16),它们通过销钉(17)可枢转地安装在耦合器(10)上。 当充电耦合器(10)插入到电动车辆的进入单元中的凹部(31)中时,引导件(21)推动盖(16)的下端(16a)打开盖子(16)。 充电耦合器(10)中的初级线圈(15)电磁耦合到凹陷(31)中的一对次级线圈(32,32)。 充电后,当将充电耦合器(10)从凹陷(31)中拉出时,隔热罩(16)被张力螺旋弹簧(18)封闭,从而保护初级线圈(15)并防止一个人 从不小心碰到它。
