摘要： A knocking sensor comprises a casing for receiving a pickup assembly including a transducer, which produces an electrical signal in accordance with engine vibrations, and a connector having at least a single pin electrically connected to the transducer. The casing comprises a threaded projection to be screwed in a screw hole of an engine, and a nut-like periphery to be rotated by a tool. The knocking sensor can be attached to the engine by means of an impact wrench, by rotating the nut-like portion. A plug connected to one end of a shielding code can be plugged in the connector to make an electrical connection between the transducer and a signal processing circuit after the knocking sensor has been attached to the engine, and therefore, the shielding code is prevented from being damaged during installation of the knocking sensor. The use of an impact wrench ensures secure attachment of the sensor, and reduces the installation time.
摘要翻译：爆震传感器包括用于接收拾取组件的壳体，该拾取器组件包括根据发动机振动产生电信号的换能器，以及具有至少一个与换能器电连接的单个销的连接器。壳体包括螺纹突起，该螺纹突起被拧入发动机的螺孔中，以及螺母状周边，由工具旋转。敲击传感器可以通过冲击扳手通过旋转螺母状部分而附接到发动机。连接到屏蔽码的一端的插头可以插入连接器中，以在爆震传感器已经附接到发动机之后在换能器和信号处理电路之间进行电连接，因此防止屏蔽码爆震传感器安装过程中损坏。使用冲击扳手确保传感器的安全连接，并减少安装时间。
