Problems solved by technology

However, on the one hand, the size of the insert is small, so it is difficult to achieve precise positioning. On the other hand, during injection molding, the injection molding material in the molten state will generate a huge impact force when it enters the mold cavity and cause the insert to shift. Therefore, There are often different degrees of eccentricity between the storage space and the lens, resulting in the eccentricity of the optical fiber in the storage space and the lens, increasing the loss of light transmission
In addition, since the lens is exposed to the outside, it is easy to be polluted or scratched, which will also increase the loss of light transmission

Embodiment Construction

[0014] see Figure 1-2 , the optical fiber connector 10 according to the preferred embodiment of the present invention comprises a transparent housing 100 with two blind holes 110 and two lens fibers 200 accommodated in the two blind holes 110 respectively. One end of the lens fiber 200 extending into the blind hole 110 is formed with a conical lens surface 210 for converging light passing through the transparent housing 100 to the lens fiber 200 .

[0015] In this way, there is no eccentric problem between the lens and the optical fiber, and the conical lens surface 210 is protected in the transparent housing 100 to avoid contamination or scratches, thus reducing the loss of light transmission.

[0016] Specifically, the transparent casing 100 is substantially rectangular, and includes a front surface 120 and a rear surface 130 opposite to the front surface 120 . The two blind holes 110 are defined on the rear surface 130 .

[0017] The lensed fiber 200 includes a fiber cor...

Abstract

The invention provides an optical fiber connector which comprises a transparent outer shell provided with a blind hole and a lens optical fiber accommodated in the blind hole. The end, stretching into the blind hole, of the lens optical fiber forms a conical lens face which is used for converging light passing through the transparent outer shell to the lens optical fiber. Therefore, the eccentricity problem between a lens and an optical fiber can not happen, the conical lens face is protected in the transparent outer shell so that the conical lens face can not be polluted or scrapped, and optical transmission loss can be lowered.

Description

technical field [0001] The invention relates to an optical fiber connector (lightpeak), in particular to an optical fiber connector which reduces the loss of light transmission. Background technique [0002] A fiber optic connector usually includes a housing and an optical fiber. Optical fibers are usually covered by protective sleeves to prevent them from being broken. The housing includes an integrally formed lens and fiber holder. The optical fiber receiving seat is formed with an accommodating space facing away from the lens and used for accommodating the optical fiber and the protective sleeve. The lens is aligned and coupled with the optical fiber in the receiving space, so that the light can be converged to the optical fiber to reduce the loss of light transmission. The casing is usually made by injection molding of a mold, and in order to form a receiving space, the mold has an insert whose shape corresponds to that of the optical fiber. However, on the one hand,...
