The invention relates to an optical fiber coupling connector and a manufacturing method of the optical fiber coupling connector. The optical fiber coupling connector comprises a plug body, a first lens embedded in the plug body, a socket body and a second lens embedded in the socket body, wherein the first lens comprises a first optical surface; the second lens comprises a second optical surface which is coupled with the first optical surface in an optical way; the plug body is molded with the first lens in an integral way by transparent plastic, and the socket body is also molded with the second lens in an integral way by the transparent plastic, wherein the melting point of the transparent plastic is lower than that of polyetherimide, and the fluidity of the transparent plastic is better than that of the polyetherimide; and the first optical surface and the second optical surface are respectively plated with a transparent film. After the optical fiber coupling connector is manufactured by the method, the optical characteristics of the optical fiber coupling connector can be maintained, and the production cost is greatly reduced.
Description
technical field [0001] The invention relates to the field of optical fiber coupling connectors, in particular to an optical fiber coupling connector and a manufacturing method thereof. Background technique [0002] Optical fiber transmission has outstanding advantages such as fast transmission speed, wide frequency bandwidth, low loss, strong anti-interference ability, high fidelity and reliable working performance, and has been more and more widely used in the communication field. [0003] In order to meet higher transmission rate requirements, fiber-optic coupling connectors with high data transmission rates have emerged as the times require. Existing optical fiber coupling connectors usually consist of a plug end and a receptacle end. The plug end and the socket end respectively include a body, an optical lens and an optical fiber. The body is provided with a blind hole. The optical lens is embedded in the body and is located in the axial direction of the blind hole. ...
