Strain relief, strain relief connector for optical waveguide and a process for the preparation of a strain relief

摘要

A strain relief, comprising:– an optical waveguide (24) with at least one optical fiber (28) and a casing (26),– a first, outer surface of the optical fiber (28) of the casing (26) is enclosed, and– wherein the enclosure (26) comprises a first inner surface and a first, outer diameter;– a metal tube (22), which surrounds the optical waveguide (24),– the metal tube (22) a first inner surface with a first, inner diameter, and– the first, inner diameter of the metallic tube (22) is greater than the first, outer diameter of the casing (26); and– a a molded crimping region of the metal hose (22) with a reduced inner volume and a compressed region of the optical waveguide (24),– wherein the molded crimping region of the metal hose (22) and the pressed area of the optical waveguide (24) have widths which are greater than their height,– the metal tube (22) in the crimping region (molded a second, inner surface and– wherein the enclosure (26) in the pressed area of the optical waveguide (26) has a second, outer surface,whereini) an axial flow of a casing material of the casing (26) along the longitudinal axis of the optical fiber (28) on the basis of a pressing operation caused by means of a frictional contact between the second inner surface of the metallic tube (22) and the second, outer surface of the casing (26), and enforceableii), by means of a combination of reduced internal volume and forced axial flow of the casing (26), an increased local density of the casing (26) and an increase in the local elasticity coefficient (of the casing (26), which is in contact with the optical fiber (28), can be generated, so that a frictional force and a consequent resistance with respect to the axial movement of the optical fiber (28) in order to optimize the tensile and / or pressure loads is increased.
