Description

Technical Field

[0001] The utility model relates to the technical field of tantalum shells, in particular to an anti-radiation heat dissipation tantalum shell. Background Technique

[0002] A tantalum shell is a shell made of tantalum material. Due to its excellent physical and chemical properties, the tantalum shell has the function of anti-radiation and relatively excellent heat dissipation performance, and has important applications in many fields. For example, in the electronic field, the tantalum shell can be used as the electrode of an electron tube, a rectifier, an electrolytic capacitor, etc.

[0003] In the prior art, when assembling the tantalum shell and the tantalum cover, the tantalum cover is generally pressed into the upper part of the inner cavity of the tantalum shell, so that the upper end of the tantalum cover is flush with the upper end of the tantalum shell. However, due to the lack of a limiting structure, the tantalum cover is likely to enter the inside of the tantalum shell too much during the pressing process, and the tantalum cover is not stable enough after installation.

[0004] Therefore, we propose an anti-radiation heat dissipation tantalum shell. Content of the Utility Model
