Abstract

The invention provides a pressure sensor and a method for manufacturing the same, and the pressure sensor comprises a housing, one end of which is provided with an accommodation cavity; a core body module which is arranged in the accommodating cavity; a connecting module which comprises a shell, wherein the shell is arranged at the end, provided with the accommodation cavity, of the shell in a sleeving mode, and the shell is machined through an injection molding technology. By means of the technical scheme, the problems that in the prior art, production procedures are complex, and the sealing effect is poor can be solved.

Description

technical field [0001] The present invention relates to the technical field of pressure sensors, in particular to a pressure sensor and a manufacturing method of the pressure sensor. Background technique [0002] Such as figure 1 As shown, the pressure sensor includes a sensor plug 1 , a sensor housing 2 , a circlip 3 , a backing ring 4 , a pressure core 5 and a sealing ring 6 . Wherein, the circlip 3 , the backing ring 4 , the pressure core 5 and the sealing ring 6 are all arranged in the sensor housing 2 . [0003] In the prior art, when assembling the pressure sensor, first put the circlip 3, backing ring 4, pressure core 5 and sealing ring 6 into the sensor housing 2, and then insert the sensor plug 1 into the sensor housing In the body 2, by disposing the silica gel 7 between the sensor plug 1 and the sensor case 2, the gap between the sensor plug 1 and the sensor case 2 is sealed with the silica gel 7. [0004] However, in the prior art, the pressure sensor is prone...
