Processing method of bundle pipe type light-duty optical cable

Abstract

The invention discloses a processing method of a bundle pipe type light-duty optical cable. First of all, two copper wires and multiple annular reinforced ribs spaced at equal intervals are symmetrically arranged along the axis of a PE sheath in the PE sheath, the multiple annular reinforced ribs are sleeved on the two copper wires along the radial direction of the PE sheath, a tubular-like a support frame is formed in the PE sheath, a center sleeve is fixed at the central portion of the PE sheath, after multiple fibers are arranged in the center sleeve, then the center sleeve is filled up with a fiber paste, the inner wall of the PE sheath is enabled to be fully supported, and thus processing of the optical cable is completed. When the optical cable encounters a corner or an area section with quite large bending amplitude, the PE sheath is deformed and distorted, at the moment, portions disposed inside the PE sheath extrude one another, the tubular frame formed by the copper wires and the reinforced ribs inside the PE sheath is correspondingly deformed in response to borne distortion stress so as to buffer the stress effect transmitted by the PE sheath to the sleeve and reduce the probability that the PE sheath is severely deformed and damaged.

Description

technical field [0001] The invention relates to the field of optical cable manufacturing, in particular to a processing method for a bundle tube type light optical cable. Background technique [0002] In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. Most optical fibers must be covered by several layers of protective structures before use. The coated cable is called an optical cable. The protective layer and insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from harming the optical fiber, such as water, fire, electric shock, etc. . [0003] The bundle tube type has a simple structure, simple manufacturing process, better protection of optical fibers than other optical cables, and the bundle tube type optical cable has the advantages of lateral pressure resistance, small cable cross-section, light weight, ...

AI Technical Summary

Problems solved by technology

However, once the existing bundle-tube optical cable encounters a corner or a region with a large bending angle during use, the protective layer of the optical cable will crack due to local stress concentration, thereby reducing the service life of the optical cable. The means to solve this problem in the prior art is to increase the filling paste in the protective layer and the hard plastic filling matrix, but this method greatly reduces the bending resistance of the optical cable, making the stressed part of the optical cable easy to break
