The crank position sensor is one of the most prominent sensors in the electronic control system of the engine, and provides a signal for confirming the ignition timing (ignition advance angle) and the crank position for detecting the piston top dead center, the crank angle and the engine speed. The structure adopted by the crankshaft position sensor is different according to different vehicle types, and can be divided into three categories of magnetic pulse type, photoelectric type and Hall type. It is typically mounted on the front end of the crankshaft, the front end of the camshaft, the flywheel, or within the distributor.
According to the Chinese patent publication No. CN208156030U, the utility model discloses a crankshaft position sensor, which comprises a crankshaft position probe, a wire harness plug-in connector and a sealing ring, wherein the sealing ring is sleeved on the outer wall of the crankshaft position probe. The utility model aims at: aiming at the problem that the installation position of the existing crankshaft position sensor is greatly limited, the crankshaft position sensor is provided. The sealing ring of the sensor can enable the sealing effect on two sides of the sensor mounting hole to be better after the sensor is mounted on the basis that the transmission of a rotating speed signal between the crankshaft position probe and the wire harness plug connector is not affected. Therefore, when the sensor is arranged at the position, the problem of leakage such as lubricating oil is not needed to be considered, the installation position range is wider, and the arrangement mode of the components in the engine compartment is more flexible.
However: some existing sensor devices are easy to fix and loose, so that cables are easy to loose, and are easy to damage after long-time abrasion.
