As a further improvement of the invention, the anode joint comprises a connecting part and a bearing cavity, wherein the connecting part is positioned in the opening, the body part of the bearing cavity is carried on the bottom wall, and the inner cavity of the bearing cavity bears the anode tube core assembly.
As a further improvement of the present invention, a ceramic metallization layer is formed on the surface of the bottom wall near the periphery of the opening, and a body portion of the bearing cavity in contact with the bottom wall is welded integrally with the ceramic metallization layer.
As a further development of the invention, the holder body comprises a ceramic layer, which constitutes the side wall and most of the bottom wall of the holder body.
The beneficial effects of the invention are as follows: through the support body that will contact with the positive pole connects the ceramic metallization layer that forms through ceramic metallization method, then through welded mode, combines positive pole connects and support body and forms overall structure, the positive pole support that constitutes from this can support the CT frame rotational speed of higher speed, the difficult phenomenon that positive pole connects and support body become flexible appears, effectively reduces the destruction effect to the battery pack glass envelope.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
The inventor of the present invention found in practical work that the current anode support is a non-integral component, the structure of the anode support is easy to loosen when the X-ray tube assembly is arranged on the CT frame rotating at a high speed, and extra mechanical vibration can increase the risk of breakage of the anode glass shell to cause early failure of the X-ray tube core, and the higher CT frame rotating speed cannot be supported. To this end, the inventors of the present invention propose an improved anode support structure that can support higher CT gantry rotational speeds while reducing the risk of anode glass shell breakage.
Fig. 1 is a schematic structural view of an anode support according to an embodiment of the present invention, as shown in fig. 1, the anode support 10 includes a support body 1 and an anode connector 2, in this embodiment, the support body 1 includes a bottom wall 11 and a side wall 12 extending obliquely upward along the bottom wall 11, the bottom wall 11 and the side wall 12 form a substantially horn-shaped accommodating cavity, the bottom wall 11 has an opening 13, and the anode connector 2 can be at least partially accommodated in the opening 13. It is understood that the structure of the bracket body 1 is not limited to this, and may take on other shapes according to actual needs.
The bracket body 1 has a ceramic metallization layer 3, specifically, in this embodiment, the bracket body 1 includes a ceramic layer and a ceramic metallization layer 3, the ceramic layer forms a side wall 12 and a majority of a bottom wall 11 of the bracket body 1, the ceramic metallization layer 3 is formed on a surface of the bottom wall 11 near a periphery of the opening 13, the anode joint 2 and the ceramic metallization layer 3 are combined into a whole, but not limited to this, the ceramic metal oxide layer 3 may be formed at other positions of the bracket body 1, so long as the anode joint 2 and the ceramic metallization layer 3 can be combined into a whole, for example, the ceramic metallization layer 3 may be formed on an inner wall surface of the opening. The ceramic metallization layer 3 may be formed on the surface of the ceramic layer by a thin film method, a thick film method, a co-firing method, or the like, for example. Methods of ceramic metallization are well known to those of ordinary skill in the art and are not described in detail herein.
The anode tap 2 comprises a connection 22 and a carrier cavity 21, the connection 22 being located in the opening 13. Specifically, the anode tap 2 is made of a metal material, and in one embodiment of the present invention, the radial width of the bearing cavity 21 is larger than the radial width of the connecting portion 22, that is, the body of the bearing cavity 21 protrudes from the connecting portion 22, so that the cavity of the bearing cavity 21 is mounted on the bottom wall 11 of the bracket body. The body of the carrier cavity 21 in contact with the bottom wall 11 is integrated with the ceramic metallization 3 by means of welding. Specifically, in the present embodiment, the inner cavity of the carrying chamber 21 is used to carry the anode die assembly 4, and generally, the anode die assembly 4 has a glass housing.
According to the anode support provided by the embodiment of the invention, the support body contacted with the anode connector forms the ceramic metallization layer through the ceramic metallization method, and then the anode connector and the support body are combined into an integral structure through a welding mode, so that the anode support formed by the anode support can support the rotating speed of the CT frame at a higher speed. Compared with the prior art that the anode connector is directly arranged on the bracket body, other components (such as the anode tube core component) are in contact and fixed, and the anode bracket provided by the embodiment of the invention is not easy to loose with the bracket body in the process of transportation or high-speed rotation, so that the damage effect on the glass shell of the tube core component is effectively reduced.
