Abstract
The utility model relates to a high pressure resistant sealing device of a shell body and a lead wire; in the common pressure sensor, as lead wire columns are directly sintered with a metal shell body by glass, the glass can not bear high pressure and is easy to damage. The high pressure resistant sealing structure consists of the shell body (1) provided with a group of tapered holes; the tapered holes are internally sintered and fixed with tapered wiring terminals (2) by glass powder (3). The utility model can serve as the sealing structure of the high pressure resistant sensor.
Description
Technical field:
The utility model relates to a kind of to high pressure resistant housing and the improvement of lead-in wire hermetically-sealed construction.
Background technology:
At present increasing to the demand of pressure transducer at Aeronautics and Astronautics and field of petrochemical industry, and also urgent day by day to the tonometric demand under the special environment condition.Therefore pressure transducer has been proposed such as high voltage bearing requirement.Common pressure transducer is owing to directly use glass sintering between stem and the metal shell, and glass bears incessantly high pressure, and is very easily damaged.
Summary of the invention:
The purpose of this utility model provides a kind of high pressure resistant housing and lead sealing equipment, and the design by bellmouth can reduce shearing force, increases anti-extrusion degree, improves bearing capacity.
Above-mentioned purpose realizes by following technical scheme:
High pressure resistant housing and lead sealing equipment, its composition comprises: housing, described housing have one group of bellmouth, are sintered to fix the taper binding post by glass dust in the described bellmouth.
Described high pressure resistant housing and lead sealing equipment, the surface of contact of described bellmouth and taper binding post are smooth or are with line.
Described high pressure resistant housing and lead sealing equipment, described taper binding post is single taper, or taper and columniform combination.
Described high pressure resistant housing and lead sealing equipment have a winding terminal in the described bellmouth.
The beneficial effects of the utility model:
The utility model is processed several bellmouths on housing, this structure can reduce shearing force, increases anti-extrusion degree, improves bearing capacity, can bear big pressure.
