Pin, described lower metal-back bottom mask is raised, and ceramic core is arranged in lower metal-back and is engaged with projection, the ceramics
Radial seal between core body and projection；Ceramic core upper surface is provided with dividing plate, and flexible board integrated chip is arranged on dividing plate upper end；Institute
The lower metal-back inwall stated, which corresponds to, has internal thread segment above dividing plate, dividing plate upper surface is then provided with what is be threadedly coupled with internal thread segment
The threaded pressure ring that dividing plate and ceramic core are fixed.
Further, raised step-like in " convex " type, ceramic core is then for Open Side Down and raised " Contraband " type being engaged
Structure.
Further, radial seal is carried out using O-ring between ceramic core and projection.
Further, lower metal-back epimere is crimped on the hypomere outer surface of plastic housing around outsourcing.
The beneficial effects of the utility model are：Explosion-proof type pressure sensor provided by the utility model, simple in construction, design
Rationally, using radial seal, dividing plate is installed additional on ceramic core, and dividing plate, ceramic core and sealing are compressed using screw clamp plate
Circle does not react with medium, and good sealing effect, pressure-resistant burst pressure is higher, applied widely.
Brief description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Raised 7. dividing plates of 2. times metal-backs of plastic housing, 3. cavity, 4. flexible board integrated chip, 5. pin 6. on 1. in figure
8. the threaded pressure ring 10.O type circles of internal thread segment 9.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of explosion-proof type pressure sensor as shown in Figure 1, including coordinate the upper plastic housing 1 being fastenedly connected and lower metal up and down
Shell 2, the lower epimere of metal-back 2 are crimped on the hypomere outer surface of plastic housing 1 around outsourcing.In the upper plastic housing 1 and lower metal-back 2
Portion is hollow to have cavity 3, and flexible board integrated chip 4 and ceramic core are provided with the cavity 3, run through in upper plastic housing 1 provided with
The pin 5 that flexible board integrated chip 4 connects, described lower metal-back 2 bottom mask projection 6, ceramic core is arranged on lower metal
It is engaged in shell 2 and with projection 6.Projection 6 is step-like in " convex " type, and then Open Side Down is engaged with raised 6 for ceramic core
" Contraband " type structure.
Radial seal is carried out using O-ring 10 between ceramic core and projection 6.Ceramic core upper surface is provided with dividing plate 7, soft
Property plate integrated chip 4 is arranged on the upper end of dividing plate 7；The described inwall of lower metal-back 2, which corresponds to the top of dividing plate 7, has internal thread segment 8, every
The upper surface of plate 7 is then provided with the threaded pressure ring 9 for being fixed dividing plate 7 and ceramic core being threadedly coupled with internal thread segment 8.Interior spiral shell
The screw thread of line section 8 can be 3/8-24UNF external screw threads, G1/4 external screw threads, 7/16-20UNF internal threads, M10*1.25 internal threads, 1/
8-27NPT external screw threads, M14*1.5 external screw threads, etc. various screw thread and fast interface.
