DISPOSITIVO PER LA SALDATURA DI TESTA DI FIBRE OTTICHE PER STRATI EPROCEDIMENTO DI SALDATURA CON IMPIEGO DI TALE DISPOSITIVO

摘要

A method of welding several optical fibers end to end in layers in a common welding plane. Each fiber (31) includes a bared portion and a covered portion. The method is applied by a device including: (a) a microplasma welding torch (40) with a vertical axis movable in said weld plane; (b) a supporting block (39) with: parallel positioning grooves for positioning the bared portions of the fibers; an opening (42) in the neighborhood of the weld plane; and a chamber (43) for slowing down the gases of the plasma disposed below said opening and connected thereto; and (c) components for gripping the covered portions of the fibers said gripping components being constituted by supports (11, 12) provided with parallel optical fiber positioning grooves. A positive pressure difference is set up between the upper portion and the lower portion of the fibers. The fibers are translated parallel to the axes of the optical fibers.
