Abstract
A kind of TO absolute pressures pressure sensor pedestal, including base body, base sleeve, acupuncture needle, base body are weldingly fixed in base sleeve, and acupuncture needle is fixed through base body and by glass insulator.Compared with prior art, the beneficial effects of the utility model are：The utility model provides a kind of TO absolute pressures pressure sensor pedestal, and baroque integrated base is divided into two parts simple in construction, and carries out machining process respectively, is then welded and fixed by stored energy welding.Two-part structure is all very simple, thus processing technology is simple, saves machining process cost.In addition, base body can be installed according to the supporting selection of model of pressure sensor pressure chip, and base sleeve can use unified standard model, the processing and assembling that make sensor are all standardized, and the man-hour during sensor production and cost of labor are also saved while processing cost is reduced.
Description
Technical field
It the utility model is related to a kind of TO absolute pressures pressure sensor pedestal.
Background technology
Existing pressure sensor pedestal is mostly integrated base, all internal millings of structural requirement of integrated base
Hole, and machining accuracy requires higher, and processing technology is excessively complicated, thus causes machining process cost too high.Simultaneously because
Pedestal belongs to integral structure, thus pressure sensor must be according to pile line operation in assembling process is produced, the production cycle
It is longer.
The content of the invention
The purpose of this utility model is to provide a kind of TO absolute pressures pressure sensor pedestal, is by base sleeve and base body two
Divide and form, parts processing, two-part structure is all very simple, thus processing technology is simple, saves machining process cost.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of TO absolute pressures pressure sensor pedestal, including base body, base sleeve, acupuncture needle, base body are weldingly fixed on pedestal
In set, acupuncture needle is fixed through base body and by glass insulator.
Seal groove is provided with the outside of the base sleeve, the lower surface of base sleeve inner chamber is provided with the tip projection of annular,
The projection is welded and fixed with base body, and the upper surface of base sleeve is additionally provided with silicon oil infilling chamber.
The base body is circular sheet-like structures, and acupuncture needle mounting hole is provided with base body.
Compared with prior art, the beneficial effects of the utility model are：
The utility model provides a kind of TO absolute pressures pressure sensor pedestal, and baroque integrated base is divided into knot
Simple two parts of structure, and machining process is carried out respectively, then it is welded and fixed by stored energy welding.Two-part structure is all very simple
It is single, thus processing technology is simple, saves machining process cost.
Base sleeve is simple in construction, and inner chamber does not need excessive hole milling to finish, and simplifies machining process technique, reduces system
Make cost.
Base body structure is more simple, and its overall structure is sheet, individually carries out hole milling processing, and mechanical processing technique is more simple
It is single, it can effectively reduce cost of manufacture.
In addition, base body can be installed according to the supporting selection of the model of pressure sensor pressure chip, and base sleeve can be with
Using unified standard model, the processing and assembling for making sensor are all standardized, also saved while processing cost is reduced
Man-hour and cost of labor during sensor production.

Embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Implementation is not limited to following embodiment.
As Figure 1-Figure 4, a kind of TO absolute pressures pressure sensor pedestal, including base body 1, base sleeve 3, acupuncture needle 5, pedestal
Body 1 is weldingly fixed in base sleeve 3, and acupuncture needle 5 is fixed through base body 1 and by glass insulator 6.
Seal groove 4 is provided with the outside of the base sleeve 3, the lower surface of the inner chamber of base sleeve 3 is provided with the sophisticated convex of annular
7 are played, the projection 7 is welded and fixed with base body 1, and the upper surface of base sleeve 3 is additionally provided with silicon oil infilling chamber 2.
The base body 1 is circular sheet-like structures, and acupuncture needle mounting hole is provided with base body 1.
O-ring seal is placed in seal groove 4, realizes sealing during pressure measurement installation.The cavity of the lower end of base body 1 is compensation
Plate mounting groove, the circuit board of temperature-compensating is carried out to pressure chip for laying.
A kind of TO absolute pressures pressure sensor pedestal of the utility model, because base body 1 and the closing of base sleeve 3 weld, encapsulation
The base body 1 of acupuncture needle is full-closed structure, and the inner chamber of base sleeve 3 is divided into two cavitys mutually completely cut off by base body 1.Using
The pressure sensor of the utility model assembling, the back side local environment of the pressure chip in it is vacuum environment, therefore measured
Pressure value is relative to the absolute pressure under vacuum condition.
A kind of TO absolute pressures pressure sensor pedestal of the utility model, for assembling absolute pressure sensor, employs metal base
Body 1 and the split structure of Metal Substrate cover for seat 3, carry out machining process, are then welded and fixed, simplify mach processing work respectively
Skill, reduce production cost.
