This application relates to an oil collecting plate for a high-pressure fuel pump. The oil collecting plate has a protrusion extending from both sides, located on the side edges. This protrusion increases the thread depth of the high-pressure fuel outlet connector, thereby increasing the effective number of thread turns and also increasing the thickness of the high-pressure sealing area, effectively blocking the impact of high-pressure fuel. To avoid stress concentration at the contact point between the high-pressure fuel outlet connector and the oil collecting plate, the original planar seal is replaced with a conical seal, improving the sealing performance of the oil collecting plate and reducing stress concentration within it. This application is applicable to the high-pressure sealing of diesel engine oil collecting plates.
