Problems solved by technology

From the analysis of kinematics theory, this method only fixes three degrees of freedom of one translation and two rotations, and it is difficult to achieve full positioning or quasi-positioning. Not only is the operation difficult and the consistency is poor, but also the verticality is difficult to guarantee. , the return loss does not meet the requirements

Embodiment Construction

[0026] The grinding fixture structure is composed of two parts: one is a rigid main board, and the other is fastening screws. image 3 Shown is a symmetrical elastic micro-deformation area, which is divided into three relatively independent and interrelated areas by left, middle, and right three parallel grooves with basically the same length: the left elastic deformation area, the right Elastic deformation zone, rigid zone of main board. The middle channel is composed of a slender slot 5, a threaded hole 4, a transition arc and a round hole 3-1. The diameter of the round hole 3-1 is φ3mm, and the transition arc of R2.5mm is smoothly connected with the middle channel 5, and its center line is located at The central circular hole 6 of the main board is in the diameter direction. The middle through groove opens on the central circular hole 6 of the main board and ends at the circular hole 3-1. The central line of the middle through groove passes through the center of circle of...

Abstract

A novel fixture for grinding MT optical fibre connector is composed of rigid main plate, clamping hole on said main plate, regulable gap of clamping hole and fastener. The clamping hole of optical fibre connector is divided by the diagonal lines of rectangular hole and arranged at both sides of regulable gap on rigid main plate. The width of gap can be regulated by fastener, that is, the aspect ratio of rectangular clamping hole is regulated. In a preferred embodiment, said regulable gap is three parallel through slots made on said main plate, which has basically equal length.

Description

technical field [0001] The invention mainly belongs to the optical fiber end surface grinding jig of an optical passive device MT optical fiber connector in the field of optical communication, including vertical grinding and inclined grinding. Background technique [0002] Among optical passive devices, fiber optic connectors are used in optical communication or optical signal transmission. Optical fiber connectors have the function of connecting optical fibers to active components, optical fibers to other passive components, optical fibers to systems and instruments, and realize the connection between optical circuits. The joint surface of the optical fiber connector is processed into a plane, a spherical surface or an inclined spherical surface according to different requirements, so that when the two connectors are joined, the insertion loss between the two is minimized, and the reflection loss meets the requirements. [0003] MT connector is a co...
