Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0039] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention provides a temperature and pressure sensor, which comprises a shell, a ceramic piece, a circuit board, a pressure sensitive element, a conductive element and a temperature sensitive element, and is characterized in that the shell is provided with a mounting cavity with an upper opening and a lower opening, the ceramic piece is arranged in the mounting cavity and is provided with a pressure hole in a penetrating manner, the ceramic piece is in sealed connection with the inner wall of the mounting cavity so as to divide the mounting cavity into an upper cavity and a medium channel, the circuit board is mounted at the upper end of the ceramic piece, the pressure sensitive element is mounted on the upper surface of the ceramic piece, covers the pressure hole and is electrically connected with the circuit board, one end of the conductive element is electrically connected with the circuit board, the other end of the conductive element penetrates through the ceramic piece and is hermetically connected with the ceramic piece through a sealant, and the temperature sensitive element is electrically connected with the conductive element.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of pressure sensors, in particular to a temperature and pressure sensor. Background technique [0002] The temperature and pressure sensor is an integrated sensor that can measure the medium pressure and temperature at the same point at the same time. The temperature and pressure sensor is suitable for the occasion of measuring the temperature of the medium while measuring the pressure, such as the measurement of the pressure and temperature of the automobile air conditioner. [0003] In the prior art, the pressure chip is usually mounted on the TO seat, and the probe of the TO seat usually needs to be sealed by a glass insulator, and the glass insulator seal is prone to micro-cracks at high temperature, and the thermal matching is poor, which affects the sealing of the temperature and pressure sensor. It is even prone to liquid leakage or air leakage, and the TO seat is affected by th...
