Description
Technical field
The utility model is related to a kind of fastener for IGCT, more particularly to a kind of for high-power thyristor
Two point form dish suppresses the pressing element backboard of tool.
Background technology
In the prior art, IGCT is particularly more than 3.5 inches of IGCT, is crimped using twin tong, installs complicated, and one
As pressing element backboard use carbon steel backboard, in the environment of big magnetic field easily produce vortex unnecessary damage is caused to high power device
Lose, it is impossible to meet and require.
The content of the invention
To overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of easy to use for high-power crystalline substance
The pressing element backboard of brake tube, it is rational in infrastructure for more than the 3.5 inches fastenings of IGCT, improve fastening effect.
To achieve the above object, the utility model is achieved through the following technical solutions：
A kind of pressing element backboard for high-power thyristor, including aluminum alloy bottom plate, spheric washer, base, fixing screws,
Aluminum alloy bottom plate two ends are provided with ball-type packing ring, and the used fixing screws of aluminum alloy bottom plate bottom center are connected with base, aluminium alloy bottom
Headspace is provided between plate and base, aluminum alloy bottom plate is cambered surface with the contact surface of base.
Described base top is plane.
Compared with prior art, the beneficial effects of the utility model are：
Suitable for more than the 3.5 inches fastenings of IGCT, it is easy to install and fix, simple structure is with low cost, easy to operate
Installation effectiveness is high, is convenient for changing single IGCT, high working efficiency, uniform force reliability.Using spheric washer power transmission, can make
Power is effectively delivered on uniform face, does not damage IGCT, meets the installation requirement of IGCT.Bottom is connected using fixing screws
Seat and aluminum alloy bottom plate, while the contact surface of the two uses cambered surface, are capable of achieving the angle adjustment between base and aluminum alloy bottom plate.

Specific embodiment
The utility model is described in detail with reference to Figure of description, it should be noted that of the present utility model
Implementation is not limited to following implementation method.
Fig. 1-Fig. 3 is seen, for the pressing element backboard of high-power thyristor 5, including aluminum alloy bottom plate 1, spheric washer 3, base
2nd, fixing screws 4, the two ends of aluminum alloy bottom plate 1 are provided with ball-type packing ring, the used fixing screws 4 of the bottom center of aluminum alloy bottom plate 1 and bottom
Seat 2 is connected, and headspace 8 is provided between aluminum alloy bottom plate 1 and base 2, and aluminum alloy bottom plate 1 is cambered surface with the contact surface of base 2,
Angle between fine-tuning aluminum alloy bottom plate 1 and base 2, enables IGCT 5 more firmly to fasten.Aluminum alloy bottom plate 1 can lead to
Cross extrudate or machining is realized.
Wherein, the top of base 2 is plane, and the bottom of aluminum alloy bottom plate 1 is provided with the arch gap matched with cambered surface, so may be used
The headspace 8 of arch is formed between aluminum alloy bottom plate 1, to facilitate the angle between adjustment aluminum alloy bottom plate 1 and base 2.
When using, this backboard is placed on fixture, the bottom of base 2 is resisted against on fixture, fixture fixes IGCT 5,
The bottom of IGCT 5 is provided with heat sink 6, and the opposite side of heat sink 6 is fixed with furniture, is then successively disc spring fixture, is determined above-mentioned
Behind the position of part, then worn by screw rod 7 and connect, then fixed against spheric washer 3 by nut, enable aluminum alloy to base plate 1 by power
Uniformly pass to IGCT 5, it is to avoid damage IGCT 5.
The utility model is applied to more than the 3.5 inches fastenings of IGCT 5, it is easy to installs and fixes, simple structure, low cost
Honest and clean, easy to operate installation effectiveness is high, is convenient for changing single IGCT 5, high working efficiency, uniform force reliability.Using ball ring
3 power transmissions are enclosed, power can be made effectively to be delivered on uniform face, IGCT 5 is not damaged, meet the installation requirement of IGCT 5.Adopt
With the connect base 2 of fixing screws 4 and aluminum alloy bottom plate 1, while the contact surface of the two uses cambered surface, it is capable of achieving base 2 and is closed with aluminium
Angle adjustment between au base plate 1.
