Description

Technical Field

[0001] The utility model relates to an aspherical double-light window protective shell, belonging to the technical field of optical communication devices. Background Art

[0002] With the development of the industry, optical communication devices are becoming more and more integrated and compact. When using single-light window protective cases, different crystals require convex mirrors with different refractive indices, so multiple types of single-light window protective cases are needed, which may cause installation errors. Summary of the Invention

[0003] According to the background problem, the problem to be solved by the present invention is:

[0004] A small-volume integrated multi-light window protective shell is designed.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An aspherical double-light window protective shell includes a protective shell body and a convex mirror light window. The protective shell body is a cover-shaped shell with a hollow interior and an open bottom. Two light window mounting openings are provided on the top of the protective shell body. The convex mirror light window is sintered on the light window mounting openings through high-temperature sintering.

[0007] Preferably, the side wall profile of the protective shell body is a racetrack shape, an ellipse shape or an 8 shape.

[0008] Preferably, the convex mirror light window is umbrella-shaped, the handle of the convex mirror light window passes through the light window installation opening, and the size and shape of the cross section of the handle are the same as those of the light window installation opening.

[0009] Preferably, a process groove is provided on the top of the protective shell body.

[0010] Preferably, there are two or more light window mounting openings.

[0011] The utility model can increase the number of light windows and change the shape of the protective shell body according to customer design needs to meet integration requirements.

[0012] The beneficial effects of the utility model are:

[0013] The protective shell is used according to multiple adjacent transistors. Compared with the traditional single-window protective shell, it occupies a smaller volume with the same number of light windows. Convex mirror light windows with different refractive indices can be integrated on the same light window protective shell, which can adapt to a more diverse transistor distribution.

[0014] This practicality meets engineering design needs, conforms to integration needs, and can adapt to more application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1

[0019] An aspherical double-light window protective shell includes a protective shell body 1 and a convex mirror light window 2. The protective shell body 1 is a cover-shaped shell with a hollow interior and an open bottom. Two light window mounting openings 3 are provided on the top of the protective shell body 1. The convex mirror light window 2 is sintered on the light window mounting openings 3 by high-temperature welding.

[0020] The side wall profile of the protective shell body 1 is a racetrack shape, an ellipse shape or an 8 shape.

[0021] The convex mirror light window 2 is umbrella-shaped, and the handle of the convex mirror light window 2 passes through the light window installation opening 3 . The size and shape of the cross section of the handle are the same as those of the light window installation opening 3 .

[0022] A process groove 4 is provided on the top of the protective shell body 1 .

[0023] There are two or more light window installation openings 3 .

[0024] The protective shell is used according to multiple adjacent transistors. Compared with the traditional single-window protective shell, it occupies a smaller volume with the same number of light windows. Convex mirror light windows 2 with different refractive indices can be integrated on the same light window protective shell 1, which can adapt to a more diverse transistor distribution.

[0025] This practicality meets engineering design needs, conforms to integration needs, and can adapt to more application scenarios.
