Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular to a shaped wire conductor cable and a preparation method and a preparation device thereof. Background Art

[0002] Core cables are cables with a specific core structure and shape, usually used in specific industrial applications and electrical engineering. The core part consists of one or more conductors, which are wrapped by insulating materials, and the whole structure can be protected by an outer sheath material. Core cables are widely used in power transmission, communication, control systems and other fields.

[0003] The existing invention patent application with application publication number CN107068280A discloses a cable, the cable comprising at least one liquid cooling tube and at least one bare conductor, the bare conductor is accommodated in the liquid cooling tube, and an insulating liquid flows between the inner wall of the liquid cooling tube and the outer wall of the bare conductor;

[0004] For example, the cable in the above technical solution is covered with an outer insulating layer to cover the bare conductor and the wire core. The cable with this structure will form a cavity area inside, so the cable has a weak anti-extrusion ability and is prone to deformation. Although a filling layer can be set for filling, it is difficult to completely fill the cavity area, and there will still be gaps, and the relative positions of the internal wire cores are unstable.

[0005] There is also an invention patent application with application publication number CN118522496A, which discloses an improved TPU material laser handheld welding line and a preparation method thereof, wherein the laser handheld welding line includes an outer sheath, a control line, a switch line, a signal line, an armored cable optical fiber and an air pipe;

[0006] As in the above technical solution, the cable is also provided with control lines, switches and signal line light functional harnesses inside. Currently, several core cables also use this method to integrate cables. When the core uses a large number of bare stranded wire cores, several bare stranded wires will be arranged in parallel instead of being twisted together.

[0075] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0076] like Figures 1 to 16As shown, the wire conductor cable of the present invention includes a star frame 1, an inner shell 2, a functional wire harness 3, a wire core 4, a reinforcement bar 5, an insulating layer 6, an armor layer 7 and a cabling layer 8.

[0077] The unfolding device 100 of the present invention comprises a carrier 1001 , an inner support 1002 , a connecting portion 10021 and a positioning portion 10022 , a forming roller 1003 and a limiting roller 1004 .

[0078] like Figures 1 to 5 As shown, the star frame 1 has a plurality of angle regions 101; the inner shell 2 is arranged in the angle region 101 of the star frame 1, the inner shell 2 is located at the center of the star frame 1, and forms an accommodating cavity 102; the functional wire harness 3 is arranged in the accommodating cavity 102; the wire core 4 is arranged in the angle region 101, and abuts against the star frame 1 and the inner shell 2, and the wire core 4 is a bare stranded wire core;

[0079] As described above, in the present type of wire conductor cable, the inner shell 2, the functional wire harness 3 and the wire core 4 are arranged depending on the angle area 101 of the star frame 1;

[0080] During preparation, the functional harness 3 is arranged to fit the inner angle of the angle area 101, and then the inner shell 2 is arranged to cooperate with the star frame 1 to form the accommodating cavity 102, thereby realizing protection of the functional harness 3;

[0081] Then, the wire core 4 is laid out in the star frame 1 in accordance with the inner shell 2, so that the functional wire harness 3 is located at the innermost side. Under the effect of this layout structure, the inner functional wire harness 3 can be effectively protected from being squeezed and damaged; relying on the star frame 1, the anti-extrusion ability of the cable can be improved, and the convenience of integration and partitioning of the functional wire harness 3 and the wire core 4 can be improved;

[0082] The wire core 4 is a bare stranded wire core. When a plurality of wire cores 4 are arranged in parallel to fill the angle area 101, they can be adaptively deformed to fit well with the inner shell 2 to fully fill the gap. They are suitable for the angle area 101 of the star frame 1, and the star frame 1 is also suitable for integrating bare stranded wire cores.

[0083] In some embodiments, the multiple angle regions 101 are used to accommodate different types of wire cores 4 .

[0084] With respect to the structural layout of the star frame 1 and the inner shell 2 , the present invention provides two embodiments.

[0085] Example 1, see Figures 1 to 7 :

[0086] like Figures 1 to 7As shown, the star frame 1 includes a first partition plate 11 and a first reinforcement layer 12, and the inner shell 2 includes an arc plate 21 and a side plate 22, wherein a plurality of first partition plates 11 are arranged in a star shape and connected to each other to form an angle area 101, and a notch 103 is provided on the side away from the center position of the first partition plate 11; side plates 22 are arranged on both sides of the arc plate 21, and the two side plates 22 abut against two adjacent first partition plates 11 to form an accommodating cavity 102; the functional wiring harness 3 is located on the inner side of the arc plate 21; and the first reinforcement layer 12 is sleeved on the star frame 1;

[0087] As described above, in this embodiment, the first partition plate 11 and the first reinforcement layer 12 of the star frame 1 are separately arranged, and the inner shell 2 is provided with a plurality of corresponding angle areas 101;

[0088] Wherein, a plurality of first partition plates 11 are connected to each other to form a star-shaped structure to form an angle area 101 for accommodating the inner shell 2, the functional wiring harness 3 and the wire core 4;

[0089] When the inner shell 2 is installed to form the accommodating cavity 102 to protect the functional wiring harness 3, the inner shell 2 is supported on the first partition plate 11 of the star frame 1 through the two side plates 22, so that when the wire core 4 is integrated and bundled, the positions of the inner shell 2 and the star frame 1 can be ensured to be relatively stable, so as to avoid the problem of misalignment caused by squeezing and slipping of the inner shell 2 during integration;

[0090] After the wire core 4 is arranged outside the inner shell 2, the first reinforcement layer 12 is arranged on the outermost side for bundling to form a complete star frame 1 to ensure the structural stability of each component;

[0091] In the present structure, in order to improve the bending resistance of the cable, a slot 103 is provided on the side of the first spacer 11 away from the center position. By setting the slot 103, the side length of the first spacer 11 is increased. When the cable is bent, the first spacer 11 can better adapt to the deformation to reduce the occurrence of tearing and ensure its service life.

[0092] like Figures 4 to 6 As shown, the star frame 1 further includes an outward expansion plate 13, which is arranged on the side of the first partition plate 11 away from the center position; the thickness of the outward expansion plate 13 is less than or equal to one half of the thickness of the first partition plate 11, and two outward expansion plates 13 are provided, which are folded relative to each other to press and hold the wire core 4;

[0093] As in the above structure, by providing the outer expansion plate 13, after the wire core 4 is assembled into the angle area 101, the outer expansion plate 13 can be folded to press the outer side of the wire core 4, thereby achieving the pre-positioning of the wire core 4, which facilitates the subsequent provision of the first reinforcement layer 12, thereby increasing the stability of each component to a certain extent;

[0094] The thickness of the outward expansion plate 13 is set to half of the first spacer plate 11, or the thickness is set to be less than half, which is convenient for integration with the first spacer plate 11 and can also reduce the inner gap after the first reinforcement layer 12 is set to ensure a compact structure.

[0095] like Figure 6 As shown, the outward expansion plate 13 may be flush with the first partition plate 11 in the initial state, and after the wire core 4 is arranged, it is folded to both sides to press and hold the wire core 4 .

[0096] like Figure 3 As shown, the arc plate 21 is concentrically arranged with the star frame 1, and the accommodating cavity 102 is fan-shaped; the length of the straight side of the accommodating cavity 102 is greater than or equal to the diameter of the functional wiring harness 3, and the accommodating cavity 102 is provided with a foam filling material 14;

[0097] As in the above structure, after the inner shell 2 is laid, the functional harness 3 cannot completely fill the accommodating cavity 102, so in order to ensure the stability of the functional harness 3, it is filled with a foaming filling material 14 to prevent the functional harness 3 from being displaced;

[0098] In order to ensure the stability of the functional harness 3, its diameter is controlled to be less than or equal to the length of the straight side of the fan-shaped cavity 102;

[0099] When the diameter of the functional harness 3 is equal to the length of the straight side of the accommodating cavity 102, it will be squeezed by the inner shell 2 and the star frame 1. Then, when the foaming material is injected, the functional harness 3 will be further squeezed to stabilize its position.

[0100] When the diameter of the functional harness 3 is smaller than the length of the straight side of the accommodating cavity 102 , the foaming material can completely fill the accommodating cavity 102 and also stabilize the position of the functional harness 3 .

[0101] Example 2, see Figures 13-16 :

[0102] The difference between this embodiment and the first embodiment is that the structures adopted by the star frame 1 and the inner shell 2 are different.

[0103] like Figures 13-15 As shown, the star frame 1 includes a second partition plate 111 and a second reinforcement layer 112, and the inner shell 2 includes a tube frame 221 and a limit plate 222, wherein the tube frame 221 is a circular tube structure, the functional wiring harness 3 is arranged in the tube frame 221, and the tube frame 221 is provided with a foam filling material 14; the limit plate 222 and the second partition plate 111 are both arranged around the tube frame 221; one side of the second partition plate 111 is plugged and limited with two limit plates 222; the other side of the plurality of second partition plates 111 is provided with a second reinforcement layer 112, and the plurality of second reinforcement layers 112 are curved and abut against each other to form an annular shell;

[0104] As described above, in this embodiment, the second partition plate 111 and the second reinforcement layer 112 are divided into multiple parts, and the second partition plate 111 and the second reinforcement layer 112 are connected to form multiple independent connection structures;

[0105] The pipe frame 221 and the limiting plate 222 are an integrated structure, which can be integrally formed by extrusion and wrapped on the functional wiring harness 3; a cavity can be formed to accommodate the functional wiring harness 3 and filled with the foaming filling material 14; or the functional wiring harness 3 can be directly extruded and wrapped, and the inner shell 2 is in direct contact with the functional wiring harness 3;

[0106] Subsequently, a star frame 1 is arranged on the inner shell 2, and the second partition plate 111 is plugged into the limit plate 222, and the wire core 4 is laid out at the same time, and then the second reinforcement layer 112 is folded over to cover the wire core 4; wherein, the second reinforcement layer 112 can be arranged on the first partition plate 11 like the arrangement structure of the outer expansion plate 13 in the first embodiment, and the thickness of the second reinforcement layer 112 is set to be less than or equal to one half of the thickness of the first partition plate 11; after all the second partition plates 111 and the second reinforcement layers 112 are laid out, the edges of adjacent second reinforcement layers 112 are in contact with each other to fully cover the wire core 4 and ensure the stability of the needle body structure.

[0107] like Fig.16 As shown, two adjacent second reinforcement layers 112 overlap each other, and the overlapping portions of the two second reinforcement layers 112 are stamped and stretched so that the thickness of the overlapping portions is smaller than the thickness of other portions;

[0108] As in the above structure, in order to further ensure the covering effect, the second reinforcement layer 112 can be set wider, so that adjacent second reinforcement layers 112 can overlap and contact each other to ensure structural stability;

[0109] In order to avoid the tightness of the second reinforcement layer 112 overlapping each other and wrapping the outer functional layer, the edge of the second reinforcement layer 112 is stamped and extended to form an overlapping section, which can reduce the thickness of the second reinforcement layer 112 at the edge, so that the second reinforcement layer 112 has a uniform thickness as a whole after overlapping each other, thereby better contacting with the outer functional layer, reducing the generation of gaps and preventing delamination problems.

[0110] Specifically, the star frame 1 is made of metal or flexible insulating material; the reinforcing strip 5 is connected to the star frame 1 and arranged along the length direction or radial direction of the star frame 1;

[0111] As in the above structure, the star frame 1 can be made of metal material to cooperate with the wire core 4 to improve the conductivity; specifically, it uses flexible metal, or relatively thin ordinary metal;

[0112] In order to adapt to different wire core integration, the star frame 1 can also be made of insulating material to ensure that different wire cores are insulated from each other;

[0113] In order to improve the structural strength of the star frame 1, a reinforcement strip 5 is arranged to improve its strength;

[0114] Specifically, the reinforcing strip 5 can be a flexible metal strip or a nylon strip, and is arranged on the first spacer plate 11 along the length direction or radial direction of the star frame 1 .

[0115] In some embodiments, the first spacer plate 11 of the star frame 1 is a mesh plate.

[0116] like Figures 1 to 5 As shown, the insulating layer 6 is sleeved on the star frame 1; the armor layer 7 is sleeved on the insulating layer 6; and the cabling layer 8 is sleeved on the armor layer 7;

[0117] As in the above structure, the insulating layer 6 is used to improve the insulation effect of the cable, the armor layer 7 is used to further improve the structural strength of the cable, and the cabling layer 8 further achieves a protective effect. For example, the cabling layer 8 adopts a shielding layer, or is formed by a composite of multiple layers of materials.

[0118] A method for preparing a medium-sized wire conductor cable according to a first embodiment of the present invention comprises the following steps:

[0119] S1. The first partition plate 11 of the incoming material star frame 1 is a strip structure, and the first partition plate 11 is fully unfolded by the unfolding device 100;

[0120] S2, laying the functional wiring harness 3 in the angle area 101 formed by the first partition plate 11, and covering it with the inner shell 2;

[0121] S3, laying out the wire core 4 in contact with the star frame 1 and the inner shell 2;

[0122] S4, wrapping the first reinforcement layer 12 on the outside to form a complete star frame 1;

[0123] S5, encapsulating the star frame 1, the inner shell 2, the functional wiring harness 3 and the wire core 4 by at least one metal layer;
