Description

The optical fiber connector

This creation is to provide a fiber optic connector, especially in the docking space of the base body, the surface of the fiber connector is clamped by the elastic arms of the plurality of fixing frames, so that the fiber connector of various specifications will not be shaken when inserted, and it is not easy Collision between the optical fiber connector and the base body occurs to avoid breakage or twisting of the optical fiber connector, thereby improving the stability of optical signal transmission.

Press, with the rapid development of current communication technology, and the use of telephone, network and other communication equipment, the distance between people is getting closer and closer, and the transmission of communication equipment is to transmit electrical or optical signals through cables As a signal transmission line, Fiber Optics, which uses optical signals as the transmission medium, has the fastest transmission method. Because the optical fiber is made of non-metallic materials such as plastic or glass, it has excellent resistance to electromagnetic and noise. The ability of interference and the advantages of high bandwidth, light weight, long signal transmission distance and good confidentiality have made optical fibers gradually replace traditional metal transmission lines.

At present, there are many types of optical fiber connectors that can be inserted into the market to transmit or receive optical signals. Please refer to Figures 9 and 10, which are the three-dimensional exploded view and side sectional view of the conventional optical fiber connector.
