AI Technical Summary
The connection between the existing tantalum shell and the tantalum cover is unstable and easy to slide and displace. The tantalum cover is prone to excessively enter the tantalum shell during assembly, and the lack of a limit structure leads to poor assembly quality.
The upper part of the inner cavity of the tantalum shell is provided with a limit ring and an extended outer frame. The outer wall of the tantalum cover is equipped with an annular limit groove and a second chamfer. The reinforcement ring is fixed with the inner wall of the tantalum shell through the limit ring. The annular protrusion is clamped with the limit groove, which increases the contact area and resistance, and guides assembly.
Improve the connection stability and assembly quality between the tantalum cover and the tantalum shell, avoid excessive entry of the tantalum cover into the tantalum shell, and enhance assembly efficiency and accuracy.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tantalum shells, in particular to a protective shell structure. Background Art
[0002] Tantalum shell is a shell made of tantalum material. Due to its excellent physical and chemical properties, tantalum shell has radiation resistance and excellent heat dissipation. It has important applications in many fields. For example, in the electronics field, tantalum shell can be used as electrodes for electron tubes, rectifiers, electrolytic capacitors, etc.
[0003] The connection between the tantalum shell and the tantalum cover in the prior art has the following disadvantages:
[0004] 1. In the existing technology, 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 prone to excessively enter the interior of the tantalum shell during press-fitting;
[0005] 2. In the prior art, after the tantalum shell is pressed into the interior of the tantalum shell, the contact area between the tantalum shell and the inner wall of the tantalum shell is small, so the resistance is small and sliding displacement is likely to occur.
[0006] To this end, we propose a protective shell structure. Utility Model Content

[0009] (2) Technical solution
[0010] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a protective shell structure, comprising a tantalum shell, an outer wall of the tantalum shell is provided with a first chamfer, a tantalum cover is press-fitted on the upper part of the inner cavity of the tantalum shell, a tantalum wire mounting hole is provided in the middle part of the outer surface of the upper end of the tantalum cover, a limit ring is fixedly installed on the upper part of the inner cavity of the tantalum shell, and an extended outer frame is provided on the outer wall of the tantalum cover.
[0011] Preferably, the extended epitaxial frame and the tantalum cover are an integrally formed structure.
[0012] Preferably, an annular limiting groove is provided on the outer ring of the outer surface of the lower end of the tantalum cover.

[0016] (3) Beneficial effects
[0017] Compared with the prior art, the present invention provides a protective shell structure with the following beneficial effects:
[0018] 1. The protective shell structure is provided with an extended outer frame, which increases the contact area between the tantalum cover and the tantalum shell after connection, increases resistance, and improves the stability between the tantalum cover and the tantalum shell after assembly.
[0019] 2. This protective shell structure facilitates the positioning of the tantalum cover by providing a limiting ring, thereby improving the quality of the tantalum cover after assembly and preventing the tantalum cover from being pressed into a deeper position inside the tantalum shell.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] This embodiment is a protective shell structure.
[0027] like Figure 1-4As shown, it includes a tantalum shell 1, the outer wall of the tantalum shell 1 is provided with a first chamfer 2, a tantalum cover 3 is pressed on the upper part of the inner cavity of the tantalum shell 1, a tantalum wire mounting hole 4 is provided in the middle of the outer surface of the upper end of the tantalum cover 3, a limit ring 5 is fixedly installed on the upper part of the inner cavity of the tantalum shell 1, and the outer wall of the tantalum cover 3 is provided with an extended outer frame 10.
[0028] The extended outer frame 10 and the tantalum cover 3 are an integrally formed structure; an annular limiting groove 9 is provided on the outer ring of the lower outer surface of the tantalum cover 3; a second chamfer 8 is provided at the position where the tantalum cover 3 is connected to the extended outer frame 10; a reinforcement ring 6 is fixedly installed between the lower outer surface of the limiting ring 5 and the inner wall of the tantalum shell 1, and an annular protrusion 7 is fixedly installed on the upper outer surface of the limiting ring 5; the outer wall of the annular protrusion 7 is clamped to the annular limiting groove 9.
[0029] It should be noted that the utility model is a protective shell structure. When assembling between the tantalum cover 3 and the tantalum shell 1, the tantalum cover 3 is pressed into the interior of the tantalum shell 1, and the pressing depth of the tantalum cover 3 is limited by the limiting ring 5, thereby improving the accuracy of assembly and improving the quality of the product. After the pressing is completed, the annular protrusion 7 is snapped into the annular limiting groove 9, thereby improving the stability of the connection between the tantalum cover 3 and the tantalum shell 1; the extended outer frame 10 is set, and after the tantalum cover 3 is pressed into the interior of the tantalum shell 1, the extended outer frame 10 increases the contact area between the tantalum cover 3 and the tantalum shell 1, thereby increasing the resistance and improving the stability of the connection between the tantalum cover 3 and the tantalum shell 1; the second chamfer 8 is set to play a guiding role, thereby improving the efficiency of assembly between the tantalum cover 3 and the tantalum shell 1, and there is no need to accurately place the tantalum cover 3 on the upper outer surface of the tantalum shell 1, thereby improving the efficiency of pressing.
