Abstract

The invention relates to an optical fiber beam expanding connector, optical fiber beam expanding contact thereof and sleeve assembly. The optical fiber beam expanding contact comprises lens and optical fiber contact pin, and also sleeve assembly. The sleeve assembly contains the sleeve connected by optical fiber contact pin. The front end cover is set at the front end of sleeve and the front clamping portion is provided in the front end cover. The rear clamping portion set relatively with the front clamping portion and used for cooperating with front clamping portion and clamping and fixing the lens is set on the sleeve. The optical fiber beam expanding connector, optical fiber beam expanding contact thereof and sleeve assembly have solved the easy pollution for lens by gluing in current technology.

Description

technical field [0001] The invention relates to an optical fiber beam expansion connector in the field of optical signal transmission, an optical fiber beam expansion contact piece and a sleeve assembly thereof. Background technique [0002] The optical fiber beam expander connector is a high-end new type of optical fiber connector. The difference between it and the traditional contact optical fiber connector is that its contact is an optical contact with an optical lens. Optical lenses can effectively expand the size of the transmitted light beam, and can efficiently transmit optical signals in a non-contact state. [0003] Existing optical fiber beam expansion connectors such as the "Fiber Optic Beam Expansion Contact and Optical Fiber Beam Expansion Connector Using the Contact" disclosed in Chinese patent CN201780391U, the optical fiber beam expansion connector includes an optical fiber beam expansion contact, an optical fiber beam expansion contact The parts include a s...
