Description

Technical Field

[0001] The utility model relates to the technical field of automobile sensors, in particular to a vehicle sensor structure with an anti-twist plug. Background Art

[0002] Automotive sensors are input devices for automotive computer systems. They convert various operating information during vehicle operation, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and transmit them to the computer so that the engine is in the best working state. Automotive sensors need to ensure reliable electrical connections during long-term use.

[0003] The automotive sensor consists of a sensor plug and a shell made of different materials, which are fixedly connected by riveting. The specific method is to directly insert the sensor plug into the shell, apply external force to rivet the sensor plug at the joint of the shell, so as to achieve the purpose of connecting the two. Since the sensor plug and the shell are made of two different materials, there is inevitably a gap in the riveted connection between the sensor plug and the shell. When the gap reaches a certain level, the sensor plug will loosen and then twist inside the shell, causing damage to the internal circuit board. Utility Model Content

After the sensor plug is riveted relative to the shell, the pin is connected to the core body and the limit pile is inserted into the limit groove to limit the relative rotation between the pin and the core body.

[0011] In an embodiment of the present invention, the number of the riveting parts is the same as the number of the pressing grooves, and a single riveting part is correspondingly riveted into one pressing groove.

[0012] In an embodiment of the present invention, the plurality of pressing grooves and the plurality of pressing blocks are arranged in an interval state on the upper edge of the convex ring.

[0013] In an embodiment of the present invention, the housing is made of metal material, and the sensor plug is made of plastic material.

[0014] As described above, the anti-twist plug vehicle sensor structure of the utility model has the following beneficial effects:
