Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific implementations described here are only used to explain the present invention, not to limit the present invention.

[0059] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. In contrast, when an element is referred to as being "directly" connected to another element, there are no intervening ele...

Abstract

The invention relates to a shell structure, an electronic component and a medical system. The shell structure comprises a first shell and a second shell, and the first shell covers the outside of thefirst shell through a plurality of first fasteners to form a shielding structure; a part, overlapped with the second shell, in the first shell comprises a first insulating layer and a first conductinglayer which are sequentially distributed from inside to outside; a part, overlapped with the first shell, in the second shell comprises a second conducting layer, a second insulating layer and a third conducting layer which are sequentially distributed from inside to outside; the first conducting layer comprises a plurality of connecting parts which are distributed at intervals along the openingdirection of the first shell, or / and the second conducting layer comprises a plurality of connecting parts which are distributed at intervals along the opening direction of the second shell, and the connecting parts are provided with through holes for the corresponding first fasteners to penetrate through. According to the invention, electromagnetic waves can be shielded, and a sparking phenomenoncan be avoided.

Description

technical field [0001] The invention relates to the field of medical mechanical devices, in particular to a casing structure, electronic components and a medical system. Background technique [0002] For each chassis-like electronic component in the magnetic resonance system, in order to meet the requirements of electromagnetic shielding, the shell is usually made of a metal plate with a certain thickness. In application, the casing generally includes a lower casing and an upper casing mounted on the outside of the lower casing by a plurality of screws, wherein the plurality of screws are distributed at intervals along the periphery of the first casing. However, when the magnetic resonance system is working, the contact parts of the upper casing and the lower casing between the two adjacent screws may spark due to vibration and friction, which in turn will cause artifacts in the magnetic resonance image. Contents of the invention [0003] Based on this, it is necessary to...
