A pressure sensor used in an air conditioner comprises a connector, a connector sealing ring, a circuit board assembly, a shielding case, a separation plate, a pressure core body, an insulation sleeve and a shell. The shell is divided into upper and lower portions. The upper portion is a cavity and the lower portion is connected to a joint of a using place. The upper portion and the lower portion are separated by an insulation sleeve placing plane. A through hole connected to an external using place is arranged on the insulation sleeve placing plane. The shielding case is provided with an inner cavity. A step is arranged in the inner cavity. The separation plate is placed below the step of the inner cavity of the shielding case and is limited by the step. The pressure core body is placed in the inner cavity of the shielding case below the separation plate. A bottom of the insulation sleeve is provided with a plane used for placing the shielding case. The plane is provided with the through hole. The through hole is connected to an internal channel of the joint of the shell. The insulation sleeve sleeves the shielding case. An upper portion of the insulation sleeve is connected to a lower portion of the connector and then the whole insulation sleeve is put into the cavity of the upper portion of the shell. An outer edge of the upper portion of the shell fastens a lower portion of the connector. The circuit board assembly is fixed to a bottom plane of the connector and enters into the inner cavity of the shielding case.
Description
technical field [0001] The invention relates to a pressure sensor, in particular to a pressure sensor suitable for air conditioners. Background technique [0002] The structure of the existing air-conditioning pressure sensor is as follows: figure 1 As shown, it includes connector 11 , flexible circuit board assembly 12 , ceramic capacitive pressure core 13 , stainless steel shell 14 , insulating paper 15 , sealing pad 6 , sealing ring retaining ring 17 , O-ring 18 , and housing 19 . The pressure medium enters the interior of the sensor through the small hole on the shell 19, passes through the small hole on the stainless steel shell 14 and acts on the ceramic capacitor pressure core 13, and the ceramic capacitor pressure core 13 converts the pressure into an electrical signal and transmits it to the flexible circuit board assembly 12. After signal processing by the flexible circuit board assembly 12 , the pressure signal is output through the connector 11 . [0003] There...
