Problems solved by technology

[0004] However, the above-mentioned fiber-optic coupling connector requires very high coupling accuracy between the lens in the fiber plug and the lens in the receptacle. If there is any error in production, assembly or use, it will seriously affect the fiber-optic coupling connector. Coupling precision, which in turn affects the transmission efficiency of the optical transmission device, and the fiber coupling connectors currently used generally use blind holes to accommodate and fix optical fibers, which requires good control of the diameter of the blind holes to avoid larger The diameter of the blind hole causes unstable displacement of the optical fiber in the blind hole, which affects the alignment and transmission efficiency of the optical fiber

Abstract

The invention provides an optical fiber coupled connector. The connector comprises an optical fiber plug and a socket matched with the optical fiber plug, wherein the optical fiber plug is used for accommodating an optical fiber; an optical lens which is optically coupled with the optical fiber and a photoelectric signal converter are arranged at the socket end; and after an optical fiber signal enters the socket and is converged once through the optical lens, an optical signal is converted into an electric signal directly through the photoelectric signal converter for transmission. By the structure of combining the optical fiber plug and the socket with the structure, the coupling accuracy of the optical fiber coupled connector is greatly improved.

Description

technical field [0001] The invention relates to the field of Universal Serial Bus (USB), in particular to an optical fiber coupling connector. Background technique [0002] The USB data transmission technology has been widely used, and USB coupling connectors of different technical standards have different data transmission rates. The current mainstream USB2.0 products in the market have a transfer rate of about 500MB / Sec, and the transfer rate of the next-generation product USB3.0 reaches 3-5G / Sec. The transmission media of these two products are metal wire transmission. In order to meet higher transmission requirements, fiber-coupled connectors with higher data transmission rates have emerged. [0003] Existing optical fiber coupling connectors include optical fiber plugs and socket ends that cooperate with each other. Optical fibers and lenses coupled with the light are respectively arranged in the optical fiber plugs and socket ends. Optical signals are emitted from th...
