Abstract
A packaging structure of a tube base housing and a switching terminal of a wide range pressure sensor comprising the base tube housing and the switching terminal, wherein the switching terminal is shaped as a cylinder, the switching terminal is packaged in the tube base housing via glass sintering, a lower end of the packaging position between the tube base housing and the switching terminal is shaped as a cone, an upper end of the packaging position between the tube base housing and the switching terminal is shaped as a boss, and the external of the tube base housing is threaded. The packaging structure is highly reliable and high in pressure resistant performance.
Description
Technical field
The utility model relates to the inner encapsulating structure of a kind of pressure transducer, is specially a kind of base housing of wide range pressure transducer and the encapsulating structure of conversion terminal.
Background technology
Existing sensors market; With OEM type presser sensor core body is that pressure transducer and the derivatives market share of core component surpasses 50%; Though the OEM core body of this structure possesses advantage flexible for installation, that application is wide, cheap; But receive its structure influence; Also there is certain limitation, as: when pressure acted on core body, the axle pressure that columned conversion terminal receives was along with being increased by the increase of measuring pressure; Surpass load that its encapsulating structure can bear will cause conversion terminal from sintered glass or conversion terminal deviate from from shell with sintered glass, how to develop that to measure the OEM type pressure transducer that range surpasses 100MPa be the problem of main required solution.
Summary of the invention
To the problem of above-mentioned existence, the purpose of the utility model is to be to provide a kind of base housing of wide range pressure transducer and encapsulating structure of conversion terminal of being applicable to, can realize that the measurement range of pressure transducer surpasses more than the 150MPa.
The utility model is realized through following content: a kind of base housing of wide range pressure transducer and the encapsulating structure of conversion terminal; Comprise base housing and conversion terminal; Conversion terminal is cylindrical; Conversion terminal is encapsulated in the base enclosure interior through glass sintering, and the lower end of encapsulation place of base enclosure interior and conversion terminal is a cone shape, and the upper end of base housing and conversion terminal encapsulation place is the boss shape.
The utility model also has following characteristic: there is screw thread the outside of described base housing.
The utlity model has the advantage of high reliability and high resistance to pressure.

Embodiment
Further specify according to Figure of description 1
A kind of base housing of wide range pressure transducer and the encapsulating structure of conversion terminal; Comprise base housing and conversion terminal, conversion terminal is cylindrical, and conversion terminal is encapsulated in the base enclosure interior through glass sintering; The encapsulation place lower end of base enclosure interior and conversion terminal is a cone shape; Changed the integrated structure of traditional round column sintered glass powder, improved strength of joint and sealing between base housing and the sintered glass, the upper end of base housing and conversion terminal encapsulation place is the boss shape; Change the structure of traditional single cylindric conversion terminal, improved strength of joint and sealing between conversion terminal and the sintered glass.There is screw thread the outside of described base housing, manufacturability and reliability that high base is connected with system under test (SUT).
Adopted aforesaid structural design, improved the whole withstand voltage properties of base, voltage endurance capability reaches more than the 150MPa.
Base in use, presser sensor chip is gluedd joint at the middle part of base upper end, the pad of sensitive chip is connected with conversion terminal through gold ball bonding.Base upper end soldering stainless steel convoluted diaphragm and measured medium are isolated, and form seal chamber with base, and filling silicon oil transmits pressure in the cavity.When pressure acts on the convoluted diaphragm, make presser sensor chip experience pressure through silicone oil, produce electric signal, reach tonometric purpose.
