Description

Technical Field

[0001] This invention relates to the field of cable technology, and in particular to a lightweight anti-interference composite cable for ships. Background Technology

[0002] Ships operate in marine environments, which place extremely stringent demands on cables. They must withstand moisture, salt corrosion, and other adverse conditions, and the ship's interior houses numerous electronic and electrical devices. Current shipboard composite cables consist of multiple cable bundles, all wrapped with a layer of tape, and then an outer protective layer. These composite cables can only fulfill control or signal transmission functions. Furthermore, the outer protective layer and tape are easily damaged. If water enters a section of the cable due to damage or other reasons, it can spread inwards along multiple cable bundles. Replacing the cable in such cases requires replacing the entire cable, significantly increasing costs. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a lightweight anti-interference composite cable for ships, which can improve the overall protection and waterproofing effects of the cable.

[0004] (II) Technical Solution To achieve the above objectives, this application provides a lightweight anti-interference composite cable for ships, comprising multiple cable bundles in the middle, with a filling layer, an outer shielding layer, an outer waterproof layer, and an outer protective layer sequentially arranged from the inside to the outside of all the cable bundles; multiple blocking components are spaced apart along the length direction on the outside of the cable bundles, the blocking components being sealed to each cable bundle, and the blocking components being located within the filling layer.

[0005] Preferably, the cable harness includes a central conductor core, an inner shielding layer is disposed outside the conductor core, and an inner waterproof layer is disposed outside the inner shielding layer. Preferably, the blocking assembly... The system includes a first plate and a second plate, with a circular sleeve between the first and second plates. Multiple first support tubes are provided on the side of the first plate away from the second plate, and these first support tubes penetrate the first plate. Multiple second support tubes are provided on the side of the second plate away from the first plate, and these second support tubes penetrate the second plate. The first and second support tubes correspond one-to-one and are coaxially aligned. All first and second support tubes are connected to the inner side of the circular sleeve. Each cable harness passes through one first support tube and one second support tube.

[0006] Preferably, a waterproof sealing layer is provided between the first support tube, the second support tube and the cable harness.

[0007] Preferably, the circular sleeve has multiple connecting ports, and the filling layer includes a first filling layer located between the two blocking components and a second filling layer located outside the blocking components; the second filling layer enters the interior of the circular sleeve through the connecting ports and is in sealed contact with the cable harness; the first filling layer and the second filling layer are integrally formed.

[0008] Preferably, all of the cable bundles are in contact with each other between the two blocking components to form a bus bundle, and the first filler layer is formed on the outside of the bus bundle.

[0009] Preferably, multiple limiting rings are provided at intervals along the length direction on the outer side of the bus bundle.

[0010] Preferably, the outer diameter of the first filling layer is smaller than the outer diameter of the second filling layer.

[0011] Preferably, the thickness of the outer protective layer outside the first filler layer is greater than the thickness of the second filler layer.

[0012] Preferably, a decorative layer is provided on the outer side of the outer protective layer. The decorative layer includes a first decorative layer located in the cable segment where the first filling layer is located and a second decorative layer located in the cable segment where the second filling layer is located. The first decorative layer and the second decorative layer are different.

[0013] (III) Beneficial Effects This invention provides a lightweight anti-interference composite cable for ships. The cable bundle's gaps are filled by an outer filling layer, and it is shielded by an outer shielding layer. An outer waterproof layer provides waterproofing, and an outer protective layer protects the cable. By incorporating blocking components, waterproofing is achieved along the cable bundle's length, preventing water from spreading along the bundle's length after a section is damaged.

[0014] By forming a bus bundle and reducing the outer diameter of the first filler layer, a thicker outer protective layer can be fabricated outside the first filler layer. This provides better protection for the bus bundle area, preventing cable damage at that location. Simultaneously, the inclusion of a blocking component reduces the risk of cable damage and, in the event of damage, prevents water from spreading along its length, facilitating future maintenance.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example This invention provides a lightweight anti-interference composite cable for ships, see [link / reference]. Figures 1-3 It includes multiple cable bundles 100 in the middle, each cable bundle 100 is used to transmit electrical signals. From the inside out, a filling layer 200, an outer shielding layer 300, an outer waterproof layer 400, and an outer protective layer 500 are sequentially arranged on the outside of all cable bundles 100. The outer filling layer 200 fills the gaps in the cable bundles 100, the outer shielding layer 300 provides shielding, the outer waterproof layer 400 provides waterproofing, and the outer protective layer 500 protects the cable.

[0018] Furthermore, multiple blocking components 600 are spaced apart along the length of the cable harness 100 on its outer side. Each blocking component 600 is sealed to each cable harness 100 and is located within the filler layer 200. The blocking components 600 provide waterproofing along the length of the cable harness 100, preventing water from spreading along its length after a section is damaged.

[0019] The cable harness 100 includes a conductor core 110 in the middle, an inner shielding layer 120 on the outside of the conductor core 110, and an inner waterproof layer 130 on the outside of the inner shielding layer 120. By providing the inner shielding layer 120 on the outside of the conductor core 110, signals from adjacent cable harnesses 100 can be shielded, preventing mutual interference. The inner waterproof layer 130 further enhances the waterproofing of the conductor core 110, preventing water from interfering with the normal operation of the conductor core 110 after a section of the cable is damaged.

[0020] The blocking component 600 includes a first plate 610 and a second plate 620, with a circular sleeve 630 disposed between the first plate 610 and the second plate 620.

[0021] On the side of the first plate 610 away from the second plate 620, a plurality of first support tubes 640 are provided, and the first support tubes 640 penetrate the first plate 610; on the side of the second plate 620 away from the first plate 610, a plurality of second support tubes 650 are provided, and the second support tubes 650 penetrate the second plate 620. The first support tubes 640 and the second support tubes 650 correspond one to one and are arranged coaxially; all the first support tubes 640 and the second support tubes 650 are connected to the inside of the circular sleeve 630; each cable bundle 100 passes through one first support tube 640 and one second support tube 650.

[0022] To enhance the blocking effect, a waterproof sealing layer 660 is provided between the first support pipe 640, the second support pipe 650 and the cable harness 100. The waterproof sealing layer 660 can seal the contact points between the cable harness 100 and the first support pipe 640 and the second support pipe 650, thereby blocking the spread of water.

[0023] The circular sleeve 630 has multiple connecting ports 631. The filling layer 200 includes a first filling layer 210 located between the two blocking components 600 and a second filling layer 220 located outside the blocking components 600. The second filling layer 220 enters the interior of the circular sleeve 630 through the connecting ports 631 and is in sealed contact with the cable harness 100. The first filling layer 210 and the second filling layer 220 are integrally formed. The filling layer 200 fills the interior of the circular sleeve 630.

[0024] All cable bundles 100 are in contact with each other between the two blocking components 600, forming a bus bundle 100a. By forming a bus bundle 100a, better protection can be provided at the location of the bus bundle 100a, thereby preventing damage to the bus bundle 100a. At the location of the blocking component 600, due to the presence of the blocking component 600, while achieving the purpose of blocking, it can also protect the inner cable bundles 100.

[0025] A first filling layer 210 is formed on the outside of the bus bundle 100a. Multiple limiting rings 140 are spaced apart along the length of the outside of the bus bundle 100a. The limiting rings 140 can limit and fix the bus bundle 100a. During cable manufacturing, multiple cable bundles 100 are fixed together at the location of the bus bundle 100a, thus preventing movement of the cable bundles 100 during the filling process of the filling layer 200, and ensuring a seamless connection between the cable bundles 100 and the filling layer 200.

[0026] The outer diameter of the first filling layer 210 is smaller than the outer diameter of the second filling layer 220. The thickness of the outer protective layer 500 outside the first filling layer 210 is greater than the thickness of the second filling layer 220. By making the outer diameter of the first filling layer 210 smaller, a thicker outer protective layer 500 can be fabricated outside the first filling layer 210, thus providing better protection for the bus bundle 100a and preventing cable damage at that location. Simultaneously, the cable incorporates the blocking component 600, reducing the risk of cable damage and, in the event of cable damage, preventing water from spreading along its length, facilitating future maintenance.

[0027] Even better, a decorative layer is provided on the outside of the outer protective layer 500. The decorative layer includes a first decorative layer 700a located in the cable segment where the first filling layer 210 is located and a second decorative layer 700b located in the cable segment where the second filling layer 220 is located. The first decorative layer 700a and the second decorative layer 700b are different. By distinguishing between the first decorative layer 700a and the second decorative layer 700b, it is easier to locate the blocking component 600 during later maintenance.
