Description

Ferrule end face grinding device

Technical Field

The utility model belongs to the optical fiber communication equipment field, concretely relates to lock pin terminal surface grinder.

Background

Optical connectors are often used in the optical communications industry to enable rapid pluggable optical fibers between different devices/modules/devices. Optical splice types are many, LC, CS, MPO, MT, etc. and ideally, the fiber-splicing faces should be clean, so properly designed optical splice splices generally do not result in scratching of the splicing faces. However, in practical situations, dust and dirt always exist, dust may be mixed on the end faces of the two ferrules butted with each other when the optical connector is butted, and slight radial relative sliding may exist on the end faces of the two ferrules contacted with each other due to the assembly gap, which may cause scratches/grinding on the end faces of the optical fibers of the ferrules, affect the optical performance and even cause the optical connector to be directly scrapped. The optical connector belongs to a high-precision part, so that the actual production and the test process need means to grind and repair the insertion core with less serious grinding. To tubulose optical joint lock pin flower polishing reprocess, there are two kinds in current solution, the first is make split type with the optical joint, and the lock pin in the optical joint can be taken out and go up the mill and reprocess, and the second is to use the cleaning rod to be stained with the grinding paste and try to reprocess.

The first solution is relatively complex in structure, the new detachable structure brings more tolerance chains, the optical precision is reduced, and the grinding process needs to be opened more, and the grinding process cannot be directly carried out on the equipment/module/device using the optical connector.
