Abstract
Disclosed is a thyristor welding crimping assembly. The thyristor welding crimping assembly comprises a thyristor chip. The two ends of the thyristor chip are electrically connected with an upper pole plate and a lower pole plate; the connection piece of the upper pole plate and the lower pole plate is integrally fixed through a fixation screw; insulation pads are arranged between the fixation screw and the upper pole plate and between the fixation screw and the lower pole plate for insulation isolation; the thyristor chip is clamped between the upper pole plate and the lower pole plate; the other surface of the lower pole plate is in crimping connection with one surface of insulation heat conduction ceramic; and the other surface of the insulation heat conduction ceramic is in crimping connection with a radiator. By adopting the technical scheme provided by the utility model, the heat dissipation performance is good, the service life is long, the processing process is simple, and the manufacturing cost is low.
Description
Technical field
The utility model relates to a kind of thyristor assembly, particularly a kind of thyristor weldering crimp assemblies.
Background technology
Thyristor is a kind of power electronic device, can cut-off operation to the electric current on circuit, in interrupting process, be difficult to accomplish zero-current switching, therefore in turn off process, can produce certain heat, these heats are very large on the turn-off characteristic impact of thyristor, therefore need the effective cooling of thyristor, in general can establish in thyristor bottom an insulating heat-conductive pottery, below insulating heat-conductive pottery, metal fin is installed, original like product complex process on market, long processing time, and when welding, temperature requirement is high, and because insulating heat-conductive ceramic coefficient is low, area is little, and adopt Plastic Package around heat conduction electrode, thereby heat radiation can only be leaned on the heat radiation of heat conduction electrode below, cause heat dispersion poor, also make product short useful life.And cause the coefficient of expansion different because insulating heat-conductive pottery and bottom electrode adopt welding manner to connect, therefore make product easily produce thermal fatigue.
Utility model content
Goal of the invention of the present utility model is to provide the thyristor weldering crimp assemblies that a kind of perfect heat-dissipating, technique are simply easy to process, cost is low, and its concrete technical scheme is:
A kind of thyristor weldering crimp assemblies, comprise thyristor chip, thyristor chip two ends electrical connection top crown and bottom crown, the connector entirety of top crown and bottom crown is fixed by fixed screw, between fixed screw and top crown and bottom crown, there is insulation spacer insulation isolation, thyristor chip is held between top crown and bottom crown, and the another side of bottom crown is connected with the crimping of insulating heat-conductive pottery one side, and the another side of insulating heat-conductive pottery is connected with radiator crimping.
Further, described thyristor chip and top crown and bottom crown be connected to welding.
Further, described thyristor weldering crimp assemblies adopts silica gel packaging around.
Further, the thyristor in this programme also can use diode to replace.
Adopt technique scheme, perfect heat-dissipating, long service life, processing technology is simple, low cost of manufacture.

Embodiment
The embodiment setting forth below represents and allows those skilled in the art to put into practice necessary information of the present utility model, and illustrates and put into practice best mode of the present utility model.Once read with reference to the accompanying drawings following description, those skilled in the art just will understand design of the present utility model and will recognize the application of these designs of not illustrating especially herein.Should be appreciated that these designs and application fall into the scope of disclosure and the accompanying claims book.
As accompanying drawing 1, a kind of thyristor weldering crimp assemblies shown in 2, comprise thyristor chip 7, thyristor chip 7 two ends electrical connection top crown 4 and bottom crowns 3, connected mode can be welding, the connector entirety of top crown 4 and bottom crown 3 is fixing by fixed screw 6, between fixed screw 6 and top crown 4 and bottom crown 3, there are insulation spacer 5 insulation isolation, thyristor chip 7 is held between top crown 4 and bottom crown 3, the another side of bottom crown 3 is connected with the 2 one side crimping of insulating heat-conductive pottery, can solve the pottery problem different with expansion of metal coefficient, the another side of insulating heat-conductive pottery 2 is connected with radiator 1 crimping, crimping can effectively improve the efficiency of production, whole thyristor weldering crimp assemblies adopts silica gel packaging around, be beneficial to the heat radiation of assembly.
As shown in Figure 3,4, also can adopt above-mentioned weldering crimping structure for diode, also can play good effect.
Thyristor in this programme also can use diode to replace.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all execution modes.And these belong to apparent variation that spirit of the present utility model extended out or variation still among protection range of the present utility model.
