Self-supporting type indoor and outdoor easily-branched optical cable and extrusion mold thereof

Abstract

The invention discloses a self-supporting type indoor and outdoor easily-branched optical cable and an extrusion mold thereof. The extrusion mold comprises a mold sleeve and a mold core, the mold coreis a disc with a conical protrusion, a pair of symmetrically-distributed mold core and mold sleeve matching rods are arranged on the disc, and the top surface of the conical protrusion is provided with a penetration-in groove of the easily-branched optical cable; the mold sleeve is a cylinder with a conical groove, the center of the cylinder is provided with an optical cable forming groove for containing the easily-branched optical cable, the two sides are provided with mold sleeve positioning holes, and the mold core and the mold sleeve are connected by enabling the mold core and mold sleevematching rods to penetrate into the mold sleeve positioning holes; and a protective sleeve material extrusion channel is arranged between the mold sleeve and the mold core. The easily-branched optical cable is stripped from outer arc surfaces of upper and lower V-shaped grooves and C-shaped gaps to the upper and lower ends of a tight-buffered optical fiber, and the tight-buffered optical fiber ofthe easy-branched optical cable can be separated from an outer protective sleeve. The optical cable has the advantages of being small in weight, easy to branch, large in core number and excellent inmechanical property.

Description

technical field [0001] The invention belongs to the field of optical cable manufacturing, and relates to a self-supporting indoor and outdoor easy-branch optical cable and an extrusion die thereof. Background technique [0002] In rural areas and some areas where houses are relatively scattered, most of them are single-family houses, and there is a certain distance between the houses. The existing laying method is to introduce a self-supporting optical cable from the light splitting point for each house. This method The construction cost is high, and the laying efficiency is low. Contents of the invention [0003] In view of the above problems, a self-supporting indoor and outdoor easy-branch optical cable can well solve the problem of optical cable laying in rural areas, effectively improve construction efficiency and reduce construction costs. This type of optical cable contains multi-core tight-buffered optical fibers, and the outer sheath can be stripped at any positi...
