Technical Field

[0001] The present application relates to the technical field of composite insulated flexible cables, and in particular to a composite insulated flexible cable. Background Art

[0002] Flexible cables are wires that transmit current. Usually, the current is transmitted point-to-point. Cables can be divided into AC cables and DC cables according to their uses. Usually, AC cables are wires that transmit higher voltage alternating current. The structure of the cable mainly includes an outer sheath, an inner sheath, and a conductor. Common transmission conductors include copper and aluminum wires. Cables include straight cables and spiral cables. Spiral cables are often used in various fields because they can be flexibly bent.

[0003] However, in actual applications, most of the existing flexible cables are usually wound and stored after production. However, during the winding process, the flexible cables will be squeezed against each other and cause different degrees of deformation. The diameter of the deformed cable will exceed the pre-buried wire tube. Therefore, it will have a certain impact on the subsequent cable threading operation and is not conducive to promotion and use.

[0004] Therefore, those skilled in the art provide a composite insulated flexible cable to solve the problems raised in the above background technology. Summary of the invention

[0005] In order to solve the problem proposed in the above background technology that during the winding process of the flexible cables, the cables will be squeezed against each other and thus deformed to varying degrees, and the diameter of the deformed cables will exceed the pre-buried wire tubes, thereby causing a certain impact on the subsequent cable threading operations and being unfavorable for promotion and use, the present application provides a composite insulated flexible cable.

[0006] A composite insulated flexible cable provided in the present application adopts the following technical solution: it includes multiple cable bodies, the outer sides of the multiple cable bodies are in contact with the same support block, the multiple cable bodies are surrounded by the outer side of the support block at equal angles, six support rods are fixedly connected to the outer side of the support block, the six support rods are grouped in pairs and the outer side of each group of support rods is sleeved with an arc-shaped support sleeve, the outer sides of the multiple cable bodies are wrapped with an insulating thin sleeve, and the outer side of the insulating thin sleeve is wrapped with a polyvinyl chloride sheath.

[0007] Preferably, the outer sides of the six support rods are each provided with a slot, and the three arc-shaped support sleeves are each fixedly connected with a hook on the inner wall of the support rod sleeve slot.

[0008] Preferably, a through hole is provided at the center of the support block.

[0009] Preferably, the outer surface of the insulating thin sleeve is coated with red epoxy zinc-rich paint.

[0010] Preferably, the interior of the polyvinyl chloride sheath is filled with annularly staggered steel wires.

[0011] Preferably, the support block, the six support rods and the three arc-shaped support sleeves are all made of plastic material.

[0012] Preferably, the plurality of cable bodies are all made of a rubber insulation layer and copper wires, and the rubber insulation layer is wrapped around the outside of the copper wires.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. By setting support blocks and arc-shaped support sleeves, during the overall production process of the cable, the support blocks can be used to fill the gaps between multiple cables to avoid the generation of gaps, thereby improving the pressure-bearing capacity and reducing the degree of deformation. At the same time, multiple arc-shaped support sleeves are installed on the outside of multiple support rods. The installed arc-shaped support sleeves can wrap the cables to a certain extent, and the arc-shaped support sleeves can directly transmit the extrusion force to the support blocks through the support rods, and the extrusion forces in different directions can be used to offset each other. In this way, the protection of the cables can be maximized during the cable winding process, and the degree of deformation can be reduced, which improves the convenience of subsequent threading operations and is conducive to promotion and use.

[0015] 2. By setting the slot and the hook, when the arc-shaped support sleeve and the support rod are installed, the hook will be engaged with the inner wall of the slot, thereby preventing the arc-shaped support sleeve and the support rod from being separated, thereby further improving the stability of the connection.

[0016] 3. By setting the through holes, when the cable is affected by the ambient temperature during use and undergoes thermal expansion and contraction, the through holes can provide sufficient space for thermal expansion and contraction, thereby preventing the cable from being deformed as a whole due to thermal expansion and contraction.

At the same time, multiple arc-shaped support sleeves 4 are installed on the outside of multiple support rods 3. The installed arc-shaped support sleeves 4 can wrap the cable to a certain extent, and the arc-shaped support sleeves 4 can directly transmit the extrusion force to the support block 2 through the support rod 3, and the extrusion forces in different directions can be used to offset each other. In this way, the protection of the cable can be maximized during the cable winding process, the degree of deformation can be reduced, the convenience for subsequent threading operations is improved, and it is conducive to popularization and use.

[0025] In the present application, a card slot is provided on the inner side of the outer sides of the six support rods 3, and a card hook 7 is fixedly connected to the inner wall of the card slot of the three arc-shaped support sleeves 4 and the support rod 3. By setting the card slot and the card hook 7, when the arc-shaped support sleeve 4 and the support rod 3 are fitted together, the card hook 7 will be engaged with the inner wall of the card slot, thereby preventing the arc-shaped support sleeve 4 and the support rod 3 from detaching, thereby further improving the stability during connection.

[0026] In the present application, a through hole 8 is opened at the center of the support block 2; by providing the through hole 8, when the cable is affected by the ambient temperature during use and undergoes thermal expansion and contraction, the through hole 8 can provide sufficient thermal expansion and contraction space, thereby preventing the cable from being deformed as a whole due to thermal expansion and contraction.

[0027] In the present application, the outer surface of the insulating sleeve 5 is coated with red epoxy zinc-rich paint; by setting the outer surface of the insulating sleeve 5 to be coated with red epoxy zinc-rich paint, the red epoxy zinc-rich paint can improve the corrosion resistance of the insulating sleeve 5.

[0028] In the present application, the interior of the polyvinyl chloride sheath 6 is filled with annular interlaced steel wires; by setting the interior of the polyvinyl chloride sheath 6 to be filled with annular interlaced steel wires, the overall load pressure and impact force of the cable can be increased, thereby enhancing the strength and rigidity of the cable.

[0029] In the present application, the support block 2, six support rods 3 and three arc-shaped support sleeves 4 are all made of plastic material; by setting the support block 2, six support rods 3 and three arc-shaped support sleeves 4 to be made of plastic material, the support block 2, six support rods 3 and three arc-shaped support sleeves 4 can have a certain elastic deformation ability, thereby avoiding breakage when being squeezed and bent.

[0030] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings.

Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0031] The implementation principle of a composite insulated flexible cable in an embodiment of the present application is as follows: during the overall production process of the cable, the support block 2 can be used to fill the gaps between multiple cables to avoid the generation of gaps, thereby improving the pressure-bearing capacity and reducing the degree of deformation. At the same time, multiple arc-shaped support sleeves 4 are mounted on the outer sides of multiple support rods 3. The installed arc-shaped support sleeves 4 can form a certain wrapping for the cable, and the arc-shaped support sleeves 4 can directly transmit the extrusion force received to the support block 2 using the support rod 3, and the extrusion forces in different directions can be used to achieve the effect of mutual offset. In this way, the protection of the cable can be maximized during the cable winding process, and the degree of deformation can be reduced, which improves the convenience of subsequent threading operations and is conducive to promotion and use. When the arc-shaped support sleeve 4 and the support rod 3 are mounted, the hook 7 will be engaged with the inner wall of the slot, thereby preventing the arc-shaped support sleeve 4 from detaching from the support rod 3. , so as to further improve the stability of the connection. When the cable is affected by the ambient temperature during use and expands and contracts, the through hole 8 can provide sufficient space for expansion and contraction, thereby avoiding the overall deformation of the cable due to expansion and contraction. The red epoxy zinc-rich paint can improve the corrosion resistance of the insulating thin sleeve 5. At the same time, when the surface of the polyvinyl chloride sheath 6 is damaged, the red epoxy zinc-rich primer will form a sharp color difference with the polyvinyl chloride sheath 6, thereby increasing the conspicuousness of the damaged position. The interior of the polyvinyl chloride sheath 6 is filled with annular staggered steel wires, thereby increasing the overall load pressure and impact force of the cable, thereby enhancing the strength and rigidity of the cable. The support block 2, the six support rods 3 and the three arc-shaped support sleeves 4 are all made of plastic materials, so that the support block 2, the six support rods 3 and the three arc-shaped support sleeves 4 have a certain elastic deformation ability, and avoid breakage when squeezed and bent.
