Description
Technical field
The utility model relates to electric and electronic technical field, in particular to the replaceable built-in electrode ceramic packing shell of one.
Background technology
Conventional electric power electron device mainly refers to thyristor, in many essential domains, still there is irreplaceable effect, but in recent years along with the development of the novel power transistors such as IGBT, MOSFET, the market space of middle low power thyristor is progressively compressed, competition is tending towards fierce, and cost problem starts to show especially.
On the other hand, device integrated, lightness, miniaturization has become a kind of trend of device technology iteration,
Therefore aluminium electrode replaces copper electrode has become the important channel that industry seeks to fall this, but the fusing point of aluminium is very low, and brazing temperature and device operating temperature gap are less than normal, and reliability is queried.
From standardization of products angle; because the factor impacts such as application scene is different, Application Areas is extensive, design theory difference; cause existing power electronic devices specification numerous; even if same specification, physical dimension is identical, but the small variations due to electrode size; often a kind of specification has just derived several hundred kinds; therefore ceramic package is all that customized type is produced, and production cost is very high, cannot accomplish scale production.
Practical novel content
Technical problem to be solved in the utility model provides a kind of replaceable built-in electrode ceramic packing shell for above-mentioned prior art; a soldering difficult problem for aluminium electrode can be avoided; reduce costs and significantly alleviator weight revolutionaryly; realize product diversification by the same ceramic package of different electrode configurations simultaneously; both met custom IC formula requirement, the large-scale production of ceramic package can have been realized again.
The technical scheme in the invention for solving the above technical problem is: a kind of replaceable built-in electrode ceramic package, including and can mutually cover ceramic base together and upper cover, described ceramic base includes anode flange, porcelain ring, anode seal bowl, gate lead pipe and built-in anode electrode; Described anode flange is welded in the upper surface of porcelain ring with one heart, described anode seal bowl is welded in the lower surface of porcelain ring with one heart, described anode flange, porcelain ring and anode seal bowl be superimposed concentric welding from top to bottom, described gate lead pipe is connected on the shell wall of porcelain ring, and described built-in anode electrode is placed in anode seal bowl;
Described upper cover includes negative electrode sealing bowl and built-in cathode electrode, and described built-in cathode electrode is placed in negative electrode sealing bowl.
Preferably, the anode locating dowel mutually agreed with and anode pilot hole it is respectively arranged with at the center of described anode seal bowl and built-in anode electrode.
Preferably, it is respectively arranged with, at the center of described negative electrode sealing bowl and built-in cathode electrode, the negative electrode locating dowel and negative electrode pilot hole mutually agreed with.
Compared with prior art, the utility model has the advantage of:
1, compared with existing welded type electrode, electrode can customize according to customer demand, and its housing parts can carry out standardized production.
2, electrode is without the need to welding, can not affect the original working accuracy of electrode because of high temperature brazing, and built-in electrode is by crimping with the comprehensively long-pending seamless of sealing bowl, and reliability is higher.
3, electrode is without the need to welding, avoids a soldering difficult problem for aluminium electrode, provides reliable technological approaches for aluminium electrode replaces copper electrode, can replace copper electrode in major applications scene, thus reduces costs revolutionaryly and significantly alleviate device weight.
