Description

Technical Field

[0001] The utility model relates to the technical field of optical cable structures, in particular to a flat optical cable hybrid cable. Background Art

[0002] With the development of optical communication networks, flat optical cables have become the main component of optical cable lines. The existing flat optical cables include a notch in the middle, which is used to tear and separate the optical unit part in the middle and the wire parts on both sides. After the notch is torn, the outer sheath of the optical unit part is also destroyed. The optical unit part at the corresponding position needs to be covered with an outer sheath before the connection operation can be carried out. Otherwise, the single-layer sheath and aramid yarn layer alone cannot effectively protect the tight-fitting optical fiber inside. Based on this, it is urgent to develop a hybrid optical cable that can quickly separate the optical unit and the wire parts on both sides, and ensure that the optical unit and the wire parts are reliably covered with an outer sheath. Thereby, the subsequent optical unit and wire parts can be used independently and reliably. Summary of the invention

[0003] In view of the above problems, the utility model provides a flat optical cable hybrid cable, which enables the optical unit and the conductor part to be quickly torn apart, and both can be reliably used as independent cables.

[0004] A flat optical hybrid cable, characterized in that it comprises:

[0005] an outer sheath, which is flat;

[0006] First sheath wire;

[0007] Second sheath wire;

[0008] and a center light unit;

[0009] In the longitudinal section state, a first sheath wire is laid on the left side of the central light unit, and a second sheath wire is laid on the right side of the central light unit; the first sheath wire, the central light unit and the second sheath wire are arranged in parallel and spaced apart; the outer sheath covers the first sheath wire, the central light unit and the second sheath wire to form an overall flat structure; the outer sheath is provided with concave first tearing notches at the upper and lower positions corresponding to the spacing area between the first sheath wire and the central light unit, and the outer sheath is provided with concave second tearing notches at the upper and lower positions corresponding to the spacing area between the central light unit and the second sheath wire.

[0010] It is further characterized by:

[0011] A color marking line is coated in the area of ​​the upper surface and the lower surface of the outer sheath corresponding to the first sheathed wire, and the color marking line is used to distinguish the first sheathed wire from the second sheathed wire, so as to facilitate subsequent wiring operations;

[0012] The upper and lower surfaces of the outer sheath corresponding to the first sheathed wire are provided with concave identification grooves, and the identification grooves are used to distinguish the first sheathed wire from the second sheathed wire, so as to facilitate subsequent wiring operations;

[0013] The identification slots are embedded with color strips of different colors, and the function of the entire hybrid cable can be easily identified through the color strips;

[0014] The first tearing notch is an inwardly concave acute-angle notch, and the acute angle of the acute-angle notch is an arc transition, ensuring that an external force is required to separate the outer sheath corresponding to the first sheath line from the outer sheath body;

[0015] The second tearing notch is an inwardly concave acute-angle notch, and the acute angle of the acute-angle notch is an arc transition, ensuring that the outer sheath corresponding to the second sheath line can be separated from the outer sheath body only by external force;

[0016] The first tearing notch and the second tearing notch are the same isosceles triangle inwardly concave notches, ensuring that the first sheath wire, the second sheath wire, and the outer sheath part of the central light unit obtained by being torn independently are all beautiful;

[0017] The central optical unit includes a plurality of tight-buffered optical fibers and a peripheral aramid yarn. The plurality of tight-buffered optical fibers enclose a central area, and then the peripheral aramid yarn is coated on the periphery of the central area. The outer sheath is coated on the periphery of the peripheral aramid yarn. Since the outer sheath will not be damaged when torn, the peripheral aramid yarn does not need to be coated with an independent sheath, thereby saving material costs.

[0018] The first sheathed wire and the second sheathed wire are sheathed wires of the same model, but the colors of the insulation layers are different;

[0019] The inner cavities of the insulating layers of the first sheathed wire and the second sheathed wire are filled with a plurality of thin copper wires.

[0020] After adopting the above technical scheme, since the outer sheath is respectively provided with a concave first tear notch at the upper and lower positions corresponding to the spacing area between the first sheath wire and the central light unit, and the outer sheath is respectively provided with a concave second tear notch at the upper and lower positions corresponding to the spacing area between the central light unit and the second sheath wire, when it is necessary to set the sheath wire and the central light unit independently, reliable tearing is completed through the first tear notch located at the upper and lower positions and the corresponding second tear notch located at the upper and lower positions, thereby obtaining the first sheath wire, the second sheath wire and the central light unit coated with independent outer sheaths, which enables the light unit and the conductor part to be quickly torn, and both can be reliably used as independent cables.

[0026] The outer sheath 10 is flat and arranged horizontally, with semicircular structures at both ends in the width direction, and its upper and lower surfaces are both flat;

[0027] The first sheathed wire 20 and the second sheathed wire 30 are the same type of sheathed wires, and the colors of the insulation layers 1 of the first sheathed wire 20 and the second sheathed wire 30 are different. In specific implementation, the central inner cavity of the first sheathed wire and the second sheathed wire is formed by a combination of 1+6 thin copper wires 2;

[0028] The central optical unit 40 includes two tight-buffered optical fibers 41 and an outer aramid yarn 42. The two tight-buffered optical fibers 41 are combined to form a central area, and then the outer aramid yarn 42 is coated on the periphery of the central area, and the outer sheath 10 is coated on the periphery of the outer aramid yarn 42. Since the outer sheath 10 will not be damaged when torn, the outer aramid yarn 42 does not need to be coated with an independent sheath, saving material costs.

[0029] In the longitudinal section state, the first sheath line 20 is laid on the left side of the central light unit 40, and the second sheath line 30 is laid on the right side of the central light unit 40. The first sheath line 20, the central light unit 40, and the second sheath line 30 are arranged in parallel and spaced apart. The outer sheath 10 covers the first sheath line 20, the central light unit 40, and the second sheath line 30 to form an overall flat structure. The outer sheath 10 is respectively provided with a concave first tear notch 3 at the upper and lower positions of the spacing area between the first sheath line 20 and the central light unit 40, and the outer sheath 10 is respectively provided with a concave second tear notch 4 at the upper and lower positions of the spacing area between the central light unit 40 and the second sheath line 30.

[0031] The first tearing notch 3 is an inwardly concave acute-angle notch, and the acute angle of the acute-angle notch is an arc transition 6, ensuring that an external force is required to separate the outer sheath corresponding to the first sheath line 20 from the outer sheath body;

[0032] The second tear notch 4 is an inwardly concave acute-angle notch, and the acute-angled position of the acute-angle notch is an arc transition 6, ensuring that an external force is required to separate the outer sheath corresponding to the second sheath line 30 from the outer sheath body.

[0033] In specific implementation, the first tear notch 3 and the second tear notch 4 are the same isosceles triangle concave notches, ensuring that the outer sheath parts of the first sheath wire 20, the second sheath wire 30 and the central light unit 40 obtained by being torn independently are all beautiful.

[0034] Its working principle is as follows: since the outer sheath is provided with a concave first tear notch at the upper and lower positions corresponding to the spacing area between the first sheath line and the central light unit, and the outer sheath is provided with a concave second tear notch at the upper and lower positions corresponding to the spacing area between the central light unit and the second sheath line, when the sheath line and the central light unit need to be set independently, reliable tearing is achieved through the first tear notch located at the upper and lower positions and the corresponding second tear notch located at the upper and lower positions, thereby obtaining the first sheath line, the second sheath line and the central light unit covered with independent outer sheaths.
