Abstract

The invention discloses a pressure sensor shell structure comprising a cylinder-shaped pedestal and a connecting plug. One end of the connecting plug is arranged in a cavity of the pedestal. The matching end part of the pedestal and the connecting plug is provided with an "O "-shaped ring. The matching side part of the pedestal and the connecting plug is provided with a groove and the "O "-shaped ring which is matched with the groove so that sealing performance of matching between the pedestal and the connecting plug is enhanced, and position of the connecting plug in the pedestal before rolling depression can be ensured and quality of the rolling depression pedestal side part is enhanced.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a housing structure of a pressure sensor. Background technique [0002] The current housing structure of the pressure sensor mainly includes a metal base and a plastic plug-in head. A cylindrical plug-in joint is arranged in the cavity of the base, and the side of the base is fixed in the base by rolling the plug-in joint. [0003] The existing shell structure has the following disadvantages: the fit between the plug connector and the base is not tight, and air leakage is prone to occur; before the edge of the base is rolled, the plug connector is installed in the base, and the plug connector and the base There is a gap between the bases, and the position is not correct, which affects the rolling quality. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a housing structure ...
