Problems solved by technology
In this structure, the V-groove as the connection unit is difficult to process, and the machining accuracy is not easy to guarantee. It is easy to affect the structural accuracy due to the easy deformation of the material, and the positioning accuracy of the optical fiber in the V-groove is not high. These factors will cause the docking quality. Decline
In addition, in the existing above-mentioned structure, it is difficult to detect the connection quality through simple operations after the optical fiber is connected, which brings inconvenience to subsequent testing and use

Embodiment Construction
[0019] Such as figure 1 As shown, the optical fiber connection unit 1 of the present invention has a ceramic rod 11 as a substrate, and a central hole 12 that runs through the front and back is opened in the center of the ceramic rod, and a radial direction that makes the central hole communicate with the outside is opened in the middle section of the ceramic rod. Hole 13. The diameter of the central hole is 0-0.001 mm larger than the diameter of the optical fiber to be connected. One end of the central hole is set as a tapered opening 14 . The ceramic rod with the central hole can be manufactured by using the existing equipment and process for processing ceramic pins.
[0020] The optical fiber connection device of the present invention may be an optical fiber connector or an optical fiber cold junction using the above optical fiber connection unit.
[0021] Such as figure 2 As shown, the optical fiber connector of the present invention is composed of a connector housing...

The invention relates to an optical fiber connection device and an optical fiber connection and detection method for detecting the connection quality of the optical fiber. The optical fiber connection unit of the present invention includes a ceramic rod as a base body, a central hole through the center of the ceramic rod is opened, and a radial hole is opened in the middle section of the ceramic rod to communicate the central hole with the outside. The advantages of the present invention are: replace the V-groove in the traditional structure with a ceramic rod with a central hole as an optical fiber connection unit, the material has good stability, is not easy to deform, and has high docking positioning accuracy and success rate; because the ceramic rod can be used in traditional optical fiber devices - Formed by adding radial holes on the basis of ceramic pins, the manufacturing process is mature, the processing is convenient, and the manufacturing cost is low.
Description
technical field [0001] The invention relates to an optical fiber connection device and an optical fiber connection and detection method for detecting the connection quality of the optical fiber. Background technique [0002] For the butt joint of two optical fibers, quick connectors or optical fiber cold junctions are traditionally used for connection. In addition to the different housing structures, these two connection methods have basically the same structural principle of the core connection unit. They both use plastic or metal V-groove parts to position and connect the ends of the two optical fibers. In this structure, the V-groove as the connection unit is difficult to process, and the machining accuracy is not easy to guarantee. It is easy to affect the structural accuracy due to the easy deformation of the material, and the positioning accuracy of the optical fiber in the V-groove is not high. These factors will cause the docking quality. Decline. In addition, in t...
