In order to align the angle or direction of the front end of the ferrule, the ferrule tail handle is provided with a plurality of slots, the relative positions of the tail handle and the ferrule are prevented from too large change by being matched with the clamping point 1 on the frame sleeve, and then the frame sleeve is matched with the guide clamping slot on the adapter through the clamping point 2, so that the alignment of the angles or the directions of the ferrules on two sides is realized.
The main problem of this positioning mode is that the ferrule tail handle and the frame sleeve (especially the frame sleeve) are affected by the requirements of machining precision and interchangeability and assembly, the dimensional tolerance and precision can only be controlled in a certain range, and the dimensional tolerance and precision are still certain tolerance through clearance fit of a plurality of positions (for example, the fit clearance between the ferrule tail handle and the clamping point 1 is about 0.1mm, the clearance between the clamping point 2 and the adapter guide clamping groove is about 0.1 mm). The accumulation of these dimensional and positional tolerances can cause a substantial reduction in the accuracy of the final product's butt joint, thereby causing a substantial reduction in the product's interchangeability and test reliability.
