Description
Technical field
The utility model relates to a kind of electronic devices and components, is specially metal discrete device triode.
Background technology
Current To-257A type metal discrete device triode is on the market in following defect, less by electric current; Copper post adopts with molybdenum plate and firmly connects, and because expansion coefficient difference pulls molybdenum sheet during high/low-temperature impact, cause the pottery of the beryllium bottom molybdenum sheet cracked cracked with insulator, thus insulation resistance is bad and products air tightness is bad.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of impact-resistant metal discrete device triode.
Concrete technical scheme is:
Metal discrete device triode, comprise housing, oxygen-free copper base plate, beryllium potsherd, molybdenum sheet, two side lead-in wires and middle leads, described housing is arranged on oxygen-free copper plate upper surface, described housing inner bottom part has beryllium potsherd, beryllium potsherd lower surface and oxygen-free copper contacts baseplate, the upper surface of beryllium potsherd connects molybdenum sheet, two described side lead-in wires lay respectively at the both sides of middle leads, described side lead-in wire and middle leads are sintered on the sidewall of housing by glass insulator, side lead-in wire is connected with molybdenum sheet by C type fine silver sheet, middle leads is connected with molybdenum sheet by copper post.
The metal discrete device triode that the utility model provides, improves lead-in wire and the annexation of molybdenum sheet, improves the impact of high-low temperature resistant.
