Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connectors, in particular to a clamp used for adapting optical fiber connectors. Background Art

[0002] The optical fiber connector fixture is a tool for fixing and clamping optical fiber connectors, which plays a very important role in the production, testing and installation of optical fiber connectors. The existing patent announcement number is CN220944799U. The patent records an optical fiber connector grinding fixture. When using it, the user inserts the optical fiber ferrule between the clamping plate on the extrusion block and the clamping plate on the groove on the hexagonal base, and then rotates the bolt to drive the extrusion block to clamp and fix the ferrule under the restriction of the limit rod and the limit groove. At the same time, during the clamping and fixing process, the elastic force of the spring can be used to avoid the situation where the surface of the ferrule is damaged due to excessive clamping force. Then, multiple ferrules are fixed on the hexagonal base in turn, and then the fixture is connected to the grinding machine through the positioning column and the inner six grooves, and then grinding can be performed. The operation is simple. You only need to turn the bolt to fix multiple ferrules, and multiple ferrules can be ground in turn. However, after the fixture recorded in the above patent is used for a long time, the clamp for clamping the ferrule cannot be used normally due to wear, and the clamp cannot be replaced, which reduces the grinding efficiency.

[0003] Based on this, a clamp for adapting an optical fiber connector is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content
