Optical fiber coupling connector

Abstract

The invention relates to an optical fiber coupling connector in coupling connection with an optical fiber. The optical fiber coupling connector comprises a body, an optical fiber accommodation groove and a cover body, wherein the body comprises a first surface and a second surface, which are opposite to each other, a third surface which is respectively connected with the first surface and the second surface, and a lens which is protruded on the first surface; the lens is provided with a light incidence surface which is positioned between the first surface and the second surface; the optical fiber accommodation groove is provided with an arc-shaped bottom surface which is used for carrying the optical fiber; the optical fiber accommodation groove is formed on the third surface and extends into the light incidence surface of the lens from the second surface, so a light emergence surface of the optical fiber can be pressed against the light incidence surface of the lens; the cover body comprises a V-shaped bearing surface; and the V-shaped bearing surface is matched with the arc-shaped bottom surface and used for clamping and fixing the optical fiber which is borne on the arc-shaped bottom surface.

Description

technical field [0001] The invention relates to an optical fiber coupling connector. Background technique [0002] Optical fiber coupling connectors are used to realize the connection between optical fibers and the transmission of optical signals. A fiber coupling connector generally includes a blind hole for accommodating an optical fiber and a lens located at the bottom of the blind hole to optically couple with the fiber. The coupling precision between the fiber and the lens determines the optical signal transmission efficiency of the fiber coupling connector. [0003] Most of the fiber-coupled connectors are made by injection molding, and generally use blind holes as the way to control and fix the optical fibers. As long as the position of the blind holes is controlled accurately, the optical fibers can be directly assembled into the blind holes to achieve accurate alignment with the lens. counterpoint. However, in the injection molding process, the outer diameter of t...

Problems solved by technology

However, in the injection molding process, the outer diameter of the core inserts used to form blind holes is mostly thin and long, so the impact of the molding material during the molding process has a great influence on the alignment of the core inserts. Large, so it is very difficult to precisely control the size of the blind hole
