The radius of first holding surface and second holding surface is inequality. The utility model discloses saving the cost, can realizing the assembly of different quotation thyristors, reduce the material kind, save the cost, avoid simultaneously obscuring makeing mistakes, make things convenient for the reliable location of screw, the convenient to use spanner assembles and dismantles.
Description
Technical field
The utility model relates to a kind of screw, particularly a kind of thyristor supporting screw of new structure.
Background technique
In electric power system, thyristor is the core parts of a lot of equipment, during use, forms thyristor press-fit integrated unit with thyristor radiator together with being alternately fitted in by several thyristors.As nucleus equipment, thyristor press-fit quality, vital effect is played to the safety of equipment, stable operation.For the thyristor that size is less, many uses positioning dowel ensures the centering of thyristor and radiator, and for larger-size thyristor, supporting screw is generally used to fix thyristor, during use, hold the negative electrode card of thyristor with supporting screw, so both can ensure that thyristor at different levels is at same center line, also facilitates the dismounting of thyristor.
Along with increasing of thyristor manufacturer, the thyristor of same specification, the card size of different manufacturers is slightly different, causes the versatility of thyristor and radiator bad like this.At present, a lot of producer solves by offering multiple screw mounting hole on radiator different radii, and the method can be dealt with problems, but the cost of radiator can be caused to increase, simultaneously in order to avoid tapped hole is interfered, some supporting screws cannot obtain best Support Position.Research finds, same specification, and the thyristor card gap of different manufacturers is not very large; For this problem, the structure of the utility model to screw is improved, and its thyristor that can meet the different card size of same specification is used.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of thyristor supporting screw of new structure, and the supporting surface of screw is designed to different radii size, and helical thread portion is provided with abnormal screw thread, and afterbody is regular hexagon structure, effectively solves the problem in background technique.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
The utility model relates to a kind of thyristor supporting screw of new structure, comprise screw body, described screw body afterbody is provided with regular hexagon structure, supporting section is provided with in the middle of described screw body, described supporting section one end is provided with the first supporting surface, the described supporting section the other end is provided with the second supporting surface, and described bolt body nose threads part is provided with abnormal screw thread.
As a kind of optimal technical scheme of the present utility model, described first supporting surface is not identical with the radius of the second supporting surface.
The beneficial effect that the utility model reaches is:
1, radiator only needs to open two holes on a radius, saves cost, can obtain best support angle simultaneously;
2, the assembling of different card thyristor can be realized, reduce material variety, save cost, avoid confusion simultaneously and make mistakes;
3, screw nose threads part, individual threads is designed to abnormity (as quadrilateral), facilitates the reliable location of screw;
4, screw afterbody is regular hexagon structure, and spanner easy to use carries out assembling and dismantling;
5, adopt the edge supports of thyristor but not centralized positioning finger setting, facilitate installation and the replacing of thyristor.
Accompanying drawing explanation

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1, the thyristor supporting screw of a kind of new structure of the utility model, comprise screw body 1, described screw body 1 afterbody is provided with regular hexagon structure 2, supporting section 3 is provided with in the middle of described screw body 1, described supporting section 3 one end is provided with the first supporting surface 4, and described supporting section 3 the other end is provided with the second supporting surface 5, and described bolt body 1 nose threads part is provided with abnormal screw thread 6.Described first supporting surface 4 is not identical with the radius of the second supporting surface 5.
First supporting surface 4 of screw body 1 intermediate support section 3 is not identical with the radius of the second supporting surface 5, achieves the support demand that a kind of screw meets different card thyristor, achieves the versatility of material.
Screw body 1 front end is provided with abnormal screw thread 6, facilitates the reliable location of screw.
Screw body 1 afterbody is regular hexagon structure 6, and spanner easy to use carries out assembling and dismantling.
As shown in Figure 2, during use, first according to the size of thyristor 8 card, confirm the radius of arc of screw body 1, when mounted, screw body 1 is fixed on radiator 7, require fixing reliable, do not rock, guarantee is simultaneously used for the center of arc section towards radiator 7 of supporting section 3, then thyristor 8 to be put on screw body 1, can to ensure that thyristor 8 and radiator 7 are at same center line.
Radiator 7 needs leave two holes on a radius, save cost, can obtain best support angle simultaneously.
Adopt the edge supports of thyristor 7 but not centralized positioning finger setting, facilitate installation and the replacing of thyristor 8.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
