机动车辆电气系统极性反转保护装置

Polarity reversal protection unit for vehicle electric systems of motor vehicles
Abstract:
A polarity reversal protection device for motor vehicles has a detection device (10), a first connection element (22) electrically connected to a supply tap (94), a second connection device (24) having the electrical potential of the vehicle body. In case of a polarity reversal, the first connection element (22) is electrically connected to the first connection element (24) via the detector device (10). Further, the reverse polarity protection device is characterized in that a insulating layer (26) is provided between the first connection element (22) and the second connection element (24), that each of the connection elements (22, 24) has at least one receptacle (36, 38) and that the detection device (10) is at least positively engaged in at least one receptacle (36, 38).
Abstract(Chinese):

用于机动车辆的极性反转保护装置具有检测装置（10），电连接到供给抽头（94）的第一连接元件（22），具有车身电位的第二连接装置（24）。 在极性反转的情况下，第一连接元件（22）经由检测器装置（10）与第一连接元件（24）电连接。 此外，反极性保护装置的特征在于，在第一连接元件（22）和第二连接元件（24）之间设置绝缘层（26），每个连接元件（22,24）至少具有 一个容器（36,38），并且所述检测装置（10）至少主动地接合在至少一个容器（36,38）中。
