Embodiment 1

[0041] A double-color double-color strip optical cable, such asfigure 1 , comprising a cable core 1 and an outer sheath 11 arranged outside the cable core 1, two colored stripes are arranged on the outer wall of the outer sheath 11, and the colored stripes are embedded in the outer sheath 11, when the colored stripes are embedded in the outer sheath 11 , the outer wall of the color bar and the outer wall of the outer sheath 11 are on the same cylindrical surface, and each color bar is composed of two color bars 12 of different colors. At this time, one color bar is composed of two kinds of color bars 12 , which can quickly identify the optical cable, which is different from the optical cable without color marking and the optical fiber cable marked with a single color.

Embodiment 2

[0043] A kind of extruder mold that manufactures above-mentioned embodiment 1, as figure 2 and image 3 , including the outer mold casing 2, the outer module 21 embedded in the outer mold casing 2, the inner module 22 arranged in the outer module 21, and the outer mold casing 2, the outer module 21 and the inner module 22 are respectively provided with coaxially distributed conical The first feed hole 23, the second feed hole 24, the third feed hole 25, the taper of the first feed hole 23 is greater than the taper of the second feed hole 24, to facilitate the entry of the outer sheath 11 material, the outer sheath The module 21 and the inner module 22 are respectively provided with a coaxially distributed first discharge port 26 and a second discharge port 27 communicating with the second feed hole 24 and the third feed hole 25. The first discharge port 26 There is a first gap between the second discharge port 27, which is convenient for the removal of the outer sheath 11 ma...

Abstract

The invention discloses a bicolor double-colorful strip optical cable and an extruder mold thereof, and relates to the field of manufacturing of optical cables. The problems that colorful strips of the same color on the left and right sides are not enough to distinguish all optical cables, and different colors need to be added on the same colorful strip to distinguish more optical cables are solved. The bicolor double-color strip optical cable is characterized by comprising a cable core and an outer sheath arranged on the cable core, several colorful strips are arranged on the outer wall of the outer sheath and embedded in the outer sheath, and each colorful strip is composed of two color strips of different colors; double-color colorful strips sleeve the outer sheath and are beneficial for cable recognition.

Description

technical field [0001] The invention relates to the field of optical cable manufacturing, more specifically, it relates to a two-color double-color strip optical cable and an extruder mold thereof. Background technique [0002] In the prior art, in order to ensure the transmission performance, mechanical performance and environmental resistance performance of the optical fiber cable, it is necessary to sheath the outer layer of the optical fiber with a sheath material such as monochromatic polyethylene, polyvinyl chloride or nylon to form an optical fiber cable. However, it is not easy to identify when multiple optical cables are laid in the same pipe and groove, which increases the difficulty of installation, maintenance and detection. [0003] The Chinese patent with the notification number CN206946057U discloses an outdoor optical cable with two-color stripes, including: an outer sheath, a double-sided plastic-coated steel strip and a cable core; the cable core is install...
