Description
Technical field
The utility model relates to a kind of flat controllable silicon.
Background technology
Plurality of advantages such as controllable silicon is claimed thyristor again, and silicon controlled rectifier has withstand voltage height, capacity is big, efficient is high, control characteristic is good, volume is little, the life-span is long, development is swift and violent.In the century application, the flat controllable silicon of the general employing of high-power thyristor rectifying device is characterized in doing two-sided cooling.The encapsulating structure form of ceramic package is generally adopted in high-power flat formula silicon controlled encapsulation at present, though ceramic material can insulate, heat-resisting because characteristics such as ceramic process is frangible, the difficult controls of impurity; Its processing request is very high; And need through the multiple working procedure in being welded on during encapsulation, complex process, cost is high; Encapsulation back yield is on the low side, does over again and need seal off devastatingly.
Summary of the invention
It is number good that the utility model technical problem to be solved provides a kind of simple and compact for structure, sealing, the flat simply and easily controllable silicon of encapsulation operation.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of flat controllable silicon; Comprise controllable silicon tube core and the shell that has pin hole; Described shell has the vestibule of axial perforation, and the controllable silicon tube core is embedded in the vestibule, closure and following closure on the metal that the both sides of controllable silicon tube core are respectively equipped with shell is fixedly connected; Following closure is fixedly sleeved in the vestibule of tube core anode tap, and connects airtight with the tube core anode; Last closure fixed cover is in the vestibule of tube core cathode terminal; And connect airtight with the tube core negative electrode, last closure is through with the line hole that is communicated with the shell pin hole, and line is provided with gate lead in the hole; One end of gate lead connects the pin of shell, and the other end connects the negative electrode of controllable silicon tube core.Said shell is preferably resin enclosure.
Adopt the flat controllable silicon of technique scheme, its global design is scientific and reasonable, and simple in structure, compact, encapsulation operation is simple and convenient, does not change and influences existing use habit, is used in high-power thyristor rectification equipment.Thermal diffusivity during work is good, and is under adverse circumstances, safe and reliable.Parts such as the last closure of tube core, shell, metal and following closure have good general interchangeability, can recycle repeatedly.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Embodiment
Shown in accompanying drawing, a kind of embodiment of the flat silicon controlled of the utility model comprises controllable silicon tube core 2 and the shell 1 that has pin hole.Present embodiment adopts resin enclosure, and it is non-friable, and is easy to process, and security performance is stable, can prolong the useful life of product.Described shell 1 is provided with the vestibule of axial perforation, and the controllable silicon tube core is embedded in the vestibule.Closure 3 and following closure 4 on the metal that the both sides of controllable silicon tube core 2 are respectively equipped with shell is fixedly connected.Present embodiment shell 1 also can be fixedly connected through other modes through neck bush 7 and last closure 3, closure 4 clampings down certainly, as be adhesively fixed, mode such as hinged securement.Following closure 4 is fixedly sleeved in the vestibule of tube core 2 anode taps, and connects airtight with the tube core anode.Last closure 3 fixed covers are in the vestibule of tube core 2 cathode terminals; And connect airtight with tube core 2 negative electrodes; Last closure 3 is through with the line hole 6 that is communicated with shell 1 pin hole; Be provided with gate lead in the line hole 6, an end of gate lead connects the pin 5 that places in shell 1 pin hole, and the other end connects controllable silicon tube core 2 negative electrodes.
Its principle is: outside through the gate lead in the pin 5 in shell 1 pin hole, the line hole 6 pilot is connected to the control utmost point of tube core 2 cathode terminals, is used for the triggering control of thyristor rectifier device circuit to the SCR control utmost point.
