| Zusammenfassung: | The air pressure sensor convenient to mount comprises a cylindrical shell and a circuit board mounted on the shell, an opening in the bottom face of the shell is mounted on the circuit board, the circuit board is circular, the diameter of the circuit board is the same as the diameter of the shell, and the circuit board is provided with an opening in the bottom face of the shell. The side face of the bottom of the shell is bent inwards to form a circle of curled edge used for tinning. According to the utility model, the diameter of the circuit board is set to be the same as the diameter of the shell, the volume of the sensor can be further reduced, and meanwhile, the bottom of the shell is bent inwards to form a circle of curled edge for tinning, so that solder paste can be intensively adsorbed between the lower side of the curled edge and the circuit board under the guidance of the curled edge during surface mounting, and the surface mounting precision is improved. Therefore, sealing failure caused by air lea |
