Abstract
This utility model provides a kind of micro-pressure sensor based on pottery pressure resistance type, including pressure port, O, ceramic core, jump ring, connector, flexible circuit plate module；It is provided with boss, fixing described O in described pressure port；Described ceramic core is arranged at the boss in described pressure port, forms radial seal；Described ceramic core is positioned by described jump ring；Described connector is riveted on described pressure port；Described ceramic core and described connector are welded by described flexible circuit plate module and realize signal of telecommunication transmission.This utility model feature is that the boss in pressure port forms radial seal with ceramic core, solves the produced hidden danger of O assembling in traditional handicraft well, also better assures that product reliability and stability in actual applications.
Description
Technical field
This utility model relates to ceramic pressure sensor encapsulation technology field, a kind of based on pottery pressure particularly to being specially
The micro-pressure sensor of resistive.
Background technology
Pottery pressure resistance type micro-pressure sensor be mainly used in automobile and industrial control field, be usually used in monitoring machine oil pressure and
Pipeline pressure, it requires higher for the media compatibility of sensor and sealing property and long-term reliability.Existing pottery
Pressure resistance type micro-pressure sensor pressure port internal seal structure design hidden danger is relatively big, and fault rate is high in actual applications, its dress
The position joining process O is uncontrollable, if by the boss top within pressure port to ceramic core diaphragm position, then product is defeated
Go out and can produce skew, if being pressed in pressure port bottom by ceramic core, the most easily being damaged by pressure by ceramic core or damaging；Connector
With pressure port riveted position many employings embedding silica gel sealing, embedding silica gel affects product appearance, and operation is more complicated, and easily shells
Fall；Welded by PCB and high temperature wire between ceramic core with connector, poor reliability.
Utility model content
This utility model, for the problems referred to above, designs and develops out a kind of micro-pressure sensor based on pottery pressure resistance type, including
Pressure port, O, ceramic core, jump ring, connector, flexible circuit plate module；
It is provided with boss, fixing described O in described pressure port；In described ceramic core and described pressure port
Boss shape radially seals；Described ceramic core is positioned by described jump ring；Described connector is riveted on described pressure port；Institute
State ceramic core and described connector to be welded by described flexible circuit plate module and realize signal of telecommunication transmission.
Further, the O in described pressure port seal groove uses hydrogenated nitrile-butadiene rubber (HNBR).
Further, described spacer ring it is provided with between described ceramic core and jump ring.
Further, described pressure port upper end is provided with described gasket seal.
This utility model feature is that the boss in pressure port forms radial seal with ceramic core, solves biography well
In system technique, the produced hidden danger of O assembling, also better assures that product reliability and stability in actual applications.
Meanwhile, pressure port upper end is provided with gasket seal, and connector compresses gasket seal, and will be patched by rotated riveting device
Part is integrated with pressure port riveted, and this mode seals reliably, and technique realizes relatively simple.
It addition, ceramic core is welded by flexible circuit plate module with connector, compare conventional high-temperature wire and row array weldering
Connecing, welding procedure is simpler, and connected mode is more reliable.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below in conjunction with the accompanying drawings, this utility model is made
Further details of explanation, wherein,
Fig. 1 a kind of micro-pressure sensor structural representation based on pottery pressure resistance type described in the utility model；
Figure is expressed as: 1-pressure port；2-ceramic core；3-O type circle；4-spacer ring；5-jump ring；6-sealing gasket
Sheet；7-connector；8-flexible circuit plate module.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing to this practicality
Novel embodiment is described in further detail.
As it is shown in figure 1, based on pottery pressure resistance type micro-pressure sensor, including pressure port 1, O 3, ceramic core 2,
Spacer ring 4, jump ring 5, gasket seal 6, connector 7, flexible circuit plate module 8, have the boss of particular design in pressure port 1
Fixing O 3, to ensure to seal reliably, ceramic core 2 manually press entangles the boss in pressure port 1, and forms footpath
To sealing, ceramic core 2 is positioned by jump ring 5, is provided with spacer ring 4 between ceramic core 2 and jump ring 5, and pressure port 1 upper end sets
Having gasket seal 6, connector 7 is integrated with pressure port 1 riveted by rotated riveting device, and compresses gasket seal 6 guarantee sealing,
Ceramic core 2 and connector 7 weld by flexible circuit plate module 8 and realizes signal of telecommunication transmission.
Obviously, above-described embodiment is only for clearly demonstrating example, and not restriction to embodiment.Right
For those of ordinary skill in the field, can also make on the basis of the above description other multi-form change or
Variation.Here without also cannot all of embodiment be given exhaustive.And the obvious change thus extended out or
Change among still in protection domain of the present utility model.
