The utility model is characterized in that the utility model is provided with a porcelain shell body, the upper part of a cavity of the porcelain shell body is provided with an opening, the diode core which is imbedded with the epoxy resin is arranged in the cavity and the two extraction electrodes of the diode core extend out outwards by the epoxy resin. The utility model has the advantages of good heat dispersion, lower cost, simple and convenient installation, etc.
Description
Technical field
The utility model relates to a kind of diode, particularly a kind of porcelain shell power diode.
Background technology
At present, TO-220 encapsulation monomer rectifier diode all needs finned when using, and the pipe price is also higher.A lot of producers are in order to reduce production costs, two normal that price is lower column type plastic package diodes are in parallel to be used, but because the inconsistency of two diode forward pressure drops, and the plastic-sealed body heat radiation is relatively poor, during practical application, if overheated burning of pipe is arranged, just cause damage of product, fail safe is relatively poor.
Summary of the invention
The utility model provides a kind of porcelain shell power diode, make its good heat dispersion performance, and price is lower.
Described a kind of porcelain shell power diode, the epoxy resin that comprises diode core, two extraction electrodes and embedding, be characterized in: a ceramic shell is arranged, the upside of this ceramic shell cavity is uncovered, be provided with diode core and encapsulated epoxy resin in the cavity, two extraction electrodes of diode core are protruding through epoxy resin.
Described ceramic shell profile and cavity all can be cuboid; A metallic plate can be set in the described cavity, the bottom of diode core is welded on the end of metallic plate, the other end of the top of diode core and metallic plate respectively with two extraction electrodes welding, embedding has epoxy resin in the cavity, and two extraction electrodes are protruding through epoxy resin.
The utility model has been owing to adopted the ceramic shell encapsulation of good heat dispersion performance, its good heat dispersion performance during application, and price is lower, simple installation.The metallic plate that one block welding has diode core and extraction electrode is set in the cavity of ceramic shell, encapsulated epoxy resin in the cavity, the heat dispersion of its pipe will be better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the syndeton schematic diagram of extraction electrode and diode core and metallic plate among Fig. 1.
As shown in Figure 1 and Figure 2, the utility model comprises epoxy resin 1, extraction electrode 2, ceramic shell 3, diode core 4, and metallic plate 5.
Ceramic shell 3 profiles are cuboid, a metallic plate 5 is set in the cavity of ceramic shell 3, the bottom of diode core 4 is welded on the end of metallic plate 5, the other end of the top of diode core 4 and metallic plate 5 respectively with 2 welding of two extraction electrodes, 1, two extraction electrode 2 of encapsulated epoxy resin protrudes upward through epoxy resin 1 in the cavity.
Embodiment
A kind of porcelain shell power diode, the epoxy resin that comprises diode core, two extraction electrodes and embedding, be characterized in a ceramic shell, the upside of this ceramic shell cavity is uncovered, a heat-conductive characteristic preferred metal plate is set in the cavity of housing, the bottom of diode core is welded on the end of metallic plate, the other end of the top of diode core and metallic plate respectively with two extraction electrodes welding, encapsulated epoxy resin in the cavity, two extraction electrodes are protruding through epoxy resin.
The ceramic shell profile is a cuboid, and stretch out up the upper end of two extraction electrodes.In addition, two extraction electrodes also can stretch out to other direction through epoxy resin.
The utility model output current is used in the 6-15A scope can not install heat abstractor additional, and simple installation, and its surface temperature rise hangs down 15-25 ℃ than the 6A diode of two parallel connections.Compare with same specification TO-220 encapsulation monomer rectifier diode, price is lower, use does not need finned.
