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 device of the shell body and the lead wire consists of the shell body (1) provided with a group of holes; the walls of the holes are provided with grooves (2); the holes are internally provided with the lead wire columns (3); the lead wire columns are sintered and fixed in the holes by glass (4); the lead wire columns are provided with circular wale (5). The utility model can serve as the sealing device of the high pressure resistant sensor.
Description
Technical field:
The utility model relates to a kind of high pressure resistant housing and 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, by the design of burr on groove in the hole and the stem, can strengthen 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 hole, the hole wall in described hole has groove, in the described hole stem is housed, described stem is fixed in the hole by glass sintering, and described stem has annular burr.
Described high pressure resistant housing and lead sealing equipment, described groove and burr can be spiral fashion or non-helical shape.
The beneficial effects of the utility model:
The utility model is processed with several holes on housing, be processed with groove on the hole wall, has burr above the stem, can increase the contact area of the glass between stem and the metal shell like this, strengthens anti-extrusion degree, improves bearing capacity, can bear big pressure.
Description of drawings:
Accompanying drawing 1 is the structural representation of this product.
