Description

Miniaturized pressure sensor

Technical Field

The utility model belongs to the technical field of pressure sensor, especially, relate to a miniaturized pressure sensor.

Background

The pressure sensor is a measuring device for converting a pressure signal into an electrical signal, and the use environment of the pressure sensor in some occasions is changed, for example, the altitude changes when the pressure sensor is used in different places, and the atmospheric pressure serving as a reference changes along with the altitude change, and if a gauge pressure sensor is adopted, the atmospheric pressure change caused by the altitude will bring measurement errors, so the pressure sensor is generally required to adopt an absolute pressure design. Due to the sealing design of the sensitive core body in the absolute pressure design, external water vapor, salt mist or dust cannot enter the core body, and the reliability of the sensor is improved.

However, the existing pressure sensor is generally connected to the wiring board of the sensor through the wiring thimble, so that the pressure sensors of different models need to be manufactured at different sensor installation positions for adaptive installation, and the cost is high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a miniaturized pressure sensor, this pressure sensor simple structure, the cost of manufacture is low, but the suitability is high, provides manifold selectivity in using.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a miniaturized pressure sensor, this miniaturized pressure sensor includes sensor base member, wire, urceolus, sensor base member bottom is threaded connection head, and the top is the metal film core, sensor base member top is equipped with the wiring board, and the wiring board is connected with the metal film core electricity, and the wiring board is equipped with the urceolus with sensor base member outside, and the urceolus inner wall is sticky with sensor base member, wiring board respectively, the wire is connected on the wiring board, and the urceolus is stretched out to the upper end, and the urceolus top is equipped with the through-hole that supplies the wire to wear out.

Furthermore, the wire is far away from the terminal plate end and is externally connected with any wiring port.

By adopting the scheme, the pressure sensor can be adapted to various automobiles through the arranged wires, and the selectivity is high.

The utility model has the advantages that: the pressure sensor has the advantages of simple structure, low manufacturing cost and high adaptability, and provides various selectivity in application.
