Description

Technical Field

[0001] The utility model belongs to the technical field of optical elements, and in particular relates to an optical communication lens tube cap. Background Art

[0002] In the field of optical fiber communication, optical transceivers mainly rely on optical elements such as spherical lenses and non-spherical lenses to achieve optical focusing. As a key coupling component in the optical communication system, the cap provides effective protection for the lens, ensuring that the lens works in a stable and suitable environment; on the other hand, the cap connects the lens with the external complex optical communication system to ensure that the optical signal can be transmitted smoothly.

[0003] The traditional installation method is usually to place the optical communication lens on the top or above the tube cap. This installation method causes the optical communication lens to be partially exposed and the contact area with the tube cap is small. During transportation and movement, the optical communication lens is easily moved due to insufficient installation, which in turn causes the optical axis to deviate and affects the collimation of the optical focus. In addition, during the molding process of the optical communication lens, due to the gaps inside the tube cap, air is easily trapped in these gaps during molding to form bubbles, which not only reduces the airtightness of the optical communication lens tube cap, but also interferes with the normal operation of the optoelectronic device. Utility Model Content

[0004] The utility model aims to provide an optical communication lens tube cap, which can effectively remove the gap gas inside the tube cap during the optical communication lens molding process, avoid the formation of bubbles in the tube cap, and reduce the damage to the surface of the optical communication lens.

[0005] To achieve the above purpose, the technical solution of the utility model is:

[0006] The optical communication lens tube cap comprises a tube cap base, a lens packaging part is arranged at the top of the tube cap base, a limiting structure is arranged around the inner wall of the lens packaging part in cooperation with the optical communication lens, a reinforcing structure is arranged inside the tube cap base in cooperation with the lens packaging part, a buffer surface one is arranged around the inner wall of the reinforcing structure in cooperation with the lens packaging part, a buffer surface two is arranged around the inner wall of the tube cap base in cooperation with the reinforcing structure, a positioning structure is arranged around the bottom of the tube cap base, a buffer surface three is arranged around the inner wall of the positioning structure in cooperation with the tube cap base, and a clamping part is arranged on the outer wall of the lens packaging part, and the height of the clamping part is equal to the height of the lens packaging part.

[0007] in:

[0008] The tube cap base and the lens packaging part are both arranged in a hollow cylindrical shape.

[0009] The outer diameter of the tube cap base is greater than the outer diameter of the lens packaging part.

[0010] The inner diameter of the tube cap base is larger than the inner diameter of the lens packaging part.

[0011] A stopper protrusion is arranged around the bottom of the positioning structure.

[0012] The cross section of the stopper protrusion is an inverted isosceles trapezoid.

[0013] The top of the outer wall of the lens packaging part is surrounded by a beveled surface 1.

[0014] The top of the outer wall of the tube cap base is surrounded by a second chamfered surface.

[0015] The buffer surface one, buffer surface two and buffer surface three are all arranged in arc-shaped grooves.

[0016] The beneficial effects of the utility model are:

[0017] By setting buffer surface one, buffer surface two, and buffer surface three, the optical communication lens and the tube cap can be tightly fitted during the optical communication lens compression molding process, and the gap gas inside the tube cap can be effectively removed to avoid the formation of bubbles in the tube cap, while reducing damage to the surface of the optical communication lens; the height of the clamping part is equal to the height of the lens packaging part, which improves the stability of the tube cap clamping and reduces the error generated during the optical communication lens compression molding process; the optical communication lens tube cap can significantly improve the stability of the optical communication lens compression molding and ensure the efficient and stable operation of the optical communication lens in the optical communication system.

[0028] The outer diameter of the cap base 1 is larger than the outer diameter of the lens packaging part 2 .

The stopper protrusion 9 is conducive to the rapid and accurate assembly of the optical communication pipe cap and the pipe socket, improving the assembly efficiency, and at the same time enhancing the stability of the connection between the optical communication pipe cap and the pipe socket, reducing the loose connection caused by external forces such as vibration and collision.
