Embodiment 1

[0029] Such as figure 1 A marine power communication composite cable is shown, including a cable core, an inner sheath 8, an outer shielding layer 9 and an outer sheath 10, which are sheathed sequentially from the inside to the outside. figure 1 and image 3 , the cable core includes a communication wire harness 11 located on the axis, a rubber tube 2 sleeved outside the communication wire harness 11, an inner helical chain 3 spirally wound along the length direction of the rubber tube 2, and a spiral type along the length direction of the rubber tube 2, etc. The support bars 4 with spacing distribution, the outer helical chain 7 spirally wound on the outside of the support bar 4 along the length direction of the cable core, and a plurality of power cores 6 ( Eight power wire cores 6) are shown in the figure;

[0030] Such as figure 2 As shown, the communication wire harness 11 is twisted by at least two groups of communication core groups 111 (three groups of communicatio...

Embodiment 2

[0035] The difference between this embodiment and embodiment 1 is:

[0036] In this example, if Figure 6 As shown, the communication harness 11 is sheathed with elastic rubber rings 13 at equal intervals along its length direction, and the outer side of the elastic rubber ring 13 is attached to the inner surface of the rubber tube 2 . The elastic rubber ring 13 can be used to limit the communication harness 11 inside the rubber tube 2, so that an annular gap can be formed between the communication harness 11 and the rubber tube 2; and the elastic rubber ring 13 itself has better elasticity, can It is compressed and deformed, so as not to affect the retraction of the rubber tube 2, and can help the rubber tube 2 to reset.

[0037] In this embodiment, each row of support bars 4 is helically distributed along the length direction of the rubber tube 2, and each power core 6 is helically wound around the outside of the inner helical chain 3 along the length direction of the rubbe...

Abstract

The invention discloses a marine power communication composite cable, which belongs to the technical field of cables and includes a cable core, an inner sheath, an outer shielding layer and an outer sheath. Spiral chain and power wire core, the communication wire harness is twisted by at least two communication wire core groups, each communication wire core group is twisted by two communication wire cores, and a central through-hole is opened on the axis of the rubber tube , the inside of the support bar is provided with a cavity connected to the central straight-through cavity, the support bars are arranged in rows at equal intervals along the rubber tube, and a power core is arranged between every two adjacent rows of support bars, and the rotation of the outer spiral chain The rotation direction of the internal spiral chain is opposite to that of the internal spiral chain. Both the internal spiral chain and the external spiral chain include alternately intermittently arranged vertical buckle circles and horizontal buckle circles, and each vertical buckle circle is buckled with the horizontal buckle circles on both sides. together. The invention has excellent torsion resistance and good bending performance, and can better protect the wire core.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a marine power communication composite cable. Background technique [0002] Marine cable is a kind of wire and cable used for power, lighting, control and communication transmission of various ships and offshore or offshore buildings, including marine power cables, marine control cables, marine communication cables, etc. Among them, marine communication cables It is used in signal transmission and control systems in various communication, electronic computers, and information processing equipment. Usually the laying space of marine cables is limited, so the armored structure adopts the wire braiding method, which is the biggest difference in structure from ordinary power, control and communication cables for land use. [0003] At present, the torsion resistance and bending performance of the existing marine communication cables are poor, which makes it easier to cause damage to t...
