1results about How to "No processing costs" patented technology

The application relates to a circular multi-core optical fiber contact piece which comprises a plug-in pin mechanism and a plug-in hole mechanism, the plug-in pin mechanism comprises a circular plug-in pin outer shell and a plug-in pin, the plug-in hole mechanism comprises a circular plug-in hole outer shell and a plug-in pin, the plug-in pin comprises a main body part and a positioning convex part formed at the tail periphery of the main body part, a plurality of optical fiber holes which are parallel to each other and are used for fixing the front-end optical fibers of an optical cable are arranged in the main body part, and the periphery of the main body part comprises a first plane and a second plane which are parallel to each other, the first plane and the second plane are connected through three circular arc surfaces, the three circular arc surfaces comprise a first circular arc surface, a second circular arc surface which realizes smooth connection between the first circular arc surface and the first plane, and a third circular arc surface which realizes smooth connection between the first circular arc surface and the second plane, and the periphery of the positioning convex part has a circular arc outer periphery surface which is consistent with the radial dimension of the first circular arc surface. The contact piece can simultaneously meet the characteristics of small size and small plug-in force.
