Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a multi-core network cable. Background Art

[0002] Currently, there are four main types of communication media available for data network cables: unshielded twisted pair, shielded twisted pair, coaxial cable and optical cable. Under poor environmental conditions, such as low temperature, oil pollution, acid and alkali corrosion, existing network cables often experience low-temperature cracking, high-temperature deformation, blurred transmission signals, deterioration, and hardening. In addition, due to the close spacing between the cables, crosstalk occurs, which affects the signal bandwidth and rate.

[0003] After searching, publication number CN217767882U discloses a multi-core network cable, which belongs to the field of cable technology. It mainly aims at the problem that the separation of multiple cores in existing products is not thorough enough, and proposes the following technical solution, including a protective sleeve composed of an anti-cracking layer, a sheath and a shielding layer, the interior of the protective sleeve is provided with a partition component for interval protection, and a core component is provided on the partition component, and the partition component includes a partition frame, and an insulating sleeve is provided on the peripheral wall of the partition frame, and a plurality of pressure-resistant pads are filled between the partition frame and the insulating sleeve. The utility model not only avoids the occurrence of crosstalk through the combination of various structures of this product, but also separates and places multiple cores inside the cable by setting a partition component, replacing the splicing between multiple soft plastic tubes used in the prior art, which is not only inconvenient to combine, but also the soft plastic is easily damaged after bending, and then crosstalk may still occur between the cores.

[0004] In the above scheme, a built-in separator component is used to separate the wire core components to achieve the purpose of preventing crosstalk. However, since the assembly of the separator component requires connecting multiple wire cores to the separator component first, the production time of the multi-core network cable is extended, the labor burden of production-related personnel is increased, and this may lead to low production capacity of this type of multi-core network cable.

[0005] To this end, a multi-core network cable is proposed, which has the advantages of anti-crosstalk effect and easy assembly, thereby solving the problems in the above-mentioned background technology. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a multi-core network cable.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-core network cable, comprising a cable body, the outer surface of the cable body is covered with an outer sheath, and the outer surface of the outer sheath is provided with a plurality of V-shaped grooves around, an armor layer is arranged on the inner side of the outer sheath, and a shielding layer is arranged on the inner side of the armor layer, an inner sheath is arranged on the inner side of the shielding layer, and a core assembly composed of a plurality of cores is arranged on the inner side of the inner sheath, a plurality of partitions are integrally injection molded on the inner surface of the inner sheath, and an inclined portion is arranged on the bottom of each partition, and a plurality of supporting horizontal bars are equidistantly arranged in the inner cavity of each partition, a strip opening is provided on the surface of the inner sheath, and an H-shaped seal is provided on the inner side of the strip opening, and sealant is filled between the H-shaped seal and the strip opening of the inner sheath.

[0008] As a further description of the above technical solution: the inclined portion of the separator is a trumpet-shaped structure, and the inclined portion of the separator is connected to the inner surface of the inner sleeve.

[0009] As a further description of the above technical solution: the wire core assembly is composed of a central wire core and a plurality of side wire cores arranged around the outer periphery of the central wire core, and a plurality of the separators are distributed between two adjacent side wire cores.

[0010] As a further description of the above technical solution: both ends of the H-shaped seal are provided with strip-shaped grooves, and the strip-shaped grooves are connected to the strip-shaped opening part of the inner sheath.

[0011] As a further description of the above technical solution: an arc-shaped concave surface is provided at one end of the separator away from the inclined portion.

[0012] As a further description of the above technical solution: the shielding layer is made of aluminum foil or tinned copper wire braided mesh material.

[0013] The utility model has the following beneficial effects:

[0014] In the utility model, a plurality of partitions are arranged around the inner ring of the inner sheath to form an anti-crosstalk structure of the wire core assembly. By covering the inner sheath on the outer surface of the wire core assembly, the plurality of partitions provided on the inner ring of the inner sheath separate the plurality of wire cores of the wire core assembly, so that two adjacent wire cores do not interfere with each other, thereby preventing the occurrence of wire core crosstalk. The inclined portion of the lower part of the partition and the plurality of supporting horizontal bars equidistantly arranged on the inner side of the partition provide limiting support for the wire core while also having an elastic buffering function, thereby improving the protective effect of the wire core assembly. Since the partition is between two adjacent wire cores, there is no need to carry out targeted insertion and assembly of the wire core, thereby reducing the difficulty of assembling the inner sheath. The V-shaped groove is opened around the outer surface of the outer sheath so that when the cable body is in a bent state, a buffer space is provided in the form of a larger angle of some V-shaped grooves to avoid rupture of the outer sheath, thereby extending the service life of the cable body.

In the open, since the surface of the inner sheath 6 is provided with an opening of a strip structure, and the inner side of the opening is sealed with an H-shaped sealing strip 9 and a sealant, it is convenient for the assembly of the inner sheath 6. Through the arrangement of multiple partitions 7, the two adjacent cores do not interfere with each other, thereby preventing the core crosstalk from occurring. The inclined portion 11 at the lower part of the partition 7 and the multiple supporting horizontal bars 8 equidistantly arranged on the inner side of the partition 7 provide limiting support for the core and also have an elastic buffering function, thereby improving the protective effect of the core assembly 5. The V-shaped groove 10 is provided around the outer surface of the outer sheath 2 to provide a buffer space in the form of a larger angle of the partial V-shaped groove 10 when the cable body 1 is bent, thereby preventing the outer sheath 2 from breaking and achieving the purpose of extending the service life of the cable body 1. The arrangement of the V-shaped groove 10 provides the outer sheath 2 with a buffer space, so that the bending of the cable body 1 can be responded to by enlarging the angle of the V-shaped groove 10.
