Detailed Description

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The utility model provides a rotatory diode of high-speed high voltage includes: base 1, electrode column 3, chip 2, tube shell 9.

The pipe shell sleeve 9 is connected with the base 1 in a welding mode, and the axis of the pipe shell sleeve 9 is perpendicular to the base 1. Chip 2 and electrode column 3 all set up in tube shell 9, and base 1 and electrode column 3 are laminated respectively to the positive and negative pole surface of chip 2. It is to be noted that the orientation of the cathode and anode surfaces of the chip 2 is not particularly limited. A sealing cover 8 is arranged at the end of the pipe housing 9 facing away from the base 1, but the electrode shaft 3 extends from the sealing cover 8.

An insulating sleeve 4, a disc spring 5 and a threaded sleeve 7 which are sleeved outside the electrode column 3 are sequentially arranged in the tube shell sleeve 9, the insulating sleeve 4 is positioned on one side, close to the base 1, of the threaded sleeve 7, gaskets 6 are respectively arranged on two sides of the disc spring 5, and the gaskets 6 are directly contacted with the disc spring 5.

The inner wall of the pipe shell sleeve 9 and the outer wall of the thread sleeve 7 are respectively provided with an internal thread and an external thread which are matched with each other. The threaded sleeve 7 is in threaded connection with the pipe shell sleeve 9. The threaded sleeve 7 is arranged in the tube sleeve 9, the electrode column 3 can be firmly pressed on the chip 2, and meanwhile, the pressure of the electrode column 3 on the chip 2 can not be too large due to the fact that the threaded sleeve 7 can linearly adjust the position and the use of the disc spring 5 is combined, so that the phenomenon that the acting force is too large due to the fact that the threaded sleeve 7 is directly pressed on the electrode column 3 is avoided, and meanwhile, the disc spring 5 also plays a role in preventing looseness of the threaded sleeve 7. The washers 6 on both sides of the disc spring 5 play a role in protection, and other parts are prevented from being crushed by the disc spring 5.

In addition, as the threaded sleeve 7 has the characteristic of being detachable, after the product is damaged, the threaded sleeve 7, the insulating sleeve 4, the disc spring 5 and the gasket 6 in the threaded sleeve can be detached, so that the damage condition of the chip 2 can be observed, the damage reason can be analyzed, and the method is obviously different from the prior art. And the pipe shell 9 and the sealing cover 8 can be recycled, which cannot be realized by the prior art.

Insulating cover 4 has located and has filled up outside between electrode post 3 and packing ring 6, and insulating cover 4 self still is provided with the cladding in the tubular structure's of electrode post 3 outer wall part, can further restrict the electric leakage like this, improves the whole high pressure resistant ability of product.

Still be provided with integrated into one piece's strengthening rib 91 at the outer wall of tube shell 9, strengthening rib 91 is used for improving the structural strength of tube shell 9 self and the structural strength of tube shell 9 and base 1 junction, and based on this, strengthening rib 91 can make the product have higher reliability under the operating mode of higher rotational speed, higher centrifugal force.

Generally speaking, because the product has been designed from the structure again for the bearing capacity of product is higher, and withstand voltage is higher, and is more firm, and the bearable rotational speed is also higher.
