Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric wires, in particular to a braided electric wire in which an electric wire and a braided net are adhesively connected to each other. Background Art
[0002] With the development of science and technology and the continuous progress of industrial technology, the consumption of electric wires is increasing day by day. An electric wire is usually a cable similar to a rope formed by twisting several or several groups of wires, with at least two wires in each group twisted together. The wires in each group are insulated from each other and are often twisted around a central wire, and the whole is covered with a highly insulating covering layer. According to different application occasions and environments, the requirements for the performance of electric wires are also different. In any case, on the one hand, due to the limited wiring environment, it is necessary for the electric wire to be curled in the direction perpendicular to the axial direction according to the wiring environment. On the other hand, the electric wire is often bent by external forces during use, such as the reciprocating movement of a robot, a robot arm, a car door, a carving machine, a machine tool processing device, a woodworking machine, a logistics conveying system, a crane, and the electric wires used in the metallurgical industry. The repetitive actions will repeatedly bend and pull the electric wire, which puts high requirements on the flexibility and tensile strength of the electric wire.
[0003] In order to improve the mechanical strength of the electric wire, a braided net (braided wire material) is usually wound around the outside of the electric wire by a braiding machine to form a braided layer. However, since there is no specific connection structure between the braided net and the electric wire, the connection strength between the braided net and the electric wire is not high, thus affecting the use of the electric wire. For example:
[0004] ① When a certain length of electric wire needs to be taken, the electric wire needs to be cut. Since the braided layer has a certain tension during the winding and braiding process, the braided layer has a certain internal stress. When the electric wire is cut, due to the internal stress of the braided layer, the cut braided layer is likely to shrink backward or even become loose, affecting the further use of the electric wire.
[0005] ② In the application of an electric wire automatic rewinder, after repeated stretching and retracting, the internal stress of the braided layer gradually decreases, causing the braided layer to gradually become loose, making it difficult for the braided layer to maintain close contact with the electric wire, and thus it is likely that the electric wire automatic rewinder cannot be retracted, affecting the further use of the electric wire automatic rewinder.
[0006] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Summary of the Utility Model
[0007] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

The wire body has a sheath layer on its outer side, and the braided layer is coated on the outer side of the sheath layer. Among them, an adhesive layer is formed on the outer side of the sheath layer by heating, so that the sheath layer and the braided layer are adhesively connected to each other through the adhesive layer.
[0009] As a further solution of the present utility model: The adhesive layer includes an adhesive layer body and a penetration layer located on the outer side of the adhesive layer body, and at least part of the penetration layer penetrates into the braided layer.

[0018] As a further solution of the present utility model: The specification of the braided layer is 50D - 1800D.
[0019] As a further solution of the present utility model: A separation layer is further provided between the insulating layer and the sheath layer, and the separation layer is attached to the outer side of the insulating layer.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0021] 1) On the outer side of the wire body, a braided mesh (braided wire material) is wound by a braiding machine to form a braided layer acting on the outer sheath layer of the wire body. Thus, through the setting of the braided layer, the properties of this braided wire such as high temperature resistance, aging resistance, and friction resistance are effectively improved;
[0022] 2) By heating this braided wire, the sheath layer is heated and at least partially melted, so that its outer side is softened by heat to form an adhesive layer. Then, through the adhesive layer, the sheath layer and the braided layer can adhere to each other, realizing the bonding and fixing of the braided layer and the sheath layer, that is, realizing the bonding and fixing of the braided layer and the wire body, and ensuring the connection strength between the braided layer and the wire body;
[0023] 3) Since the braided layer can be bonded and fixed to the wire body, the tensile strength is effectively improved, and the surface becomes more flat, compliant, and not prone to phenomena such as fuzzing and fly wire; also, during the cutting process, the braided layer at the cut will not shrink back or become loose (dispersed), demonstrating the non-opening property of this braided wire, which is more conducive to peeling processing, welding, etc.; and when coiling or stretching, the braided layer on the surface is not prone to loosening, and the overall practicality is extremely strong;
[0024] 4) During the heating process of the sheath layer, its melt can at least partially penetrate along the inner surface gap of the braided layer to form a penetration layer. Through the setting of the penetration layer, the sheath layer and the braided layer can penetrate each other, thus effectively strengthening the connection contact area between the wire body and the braided layer, and further enhancing the bonding strength between the braided layer and the wire body;
[0025] 5) During the heating process of the sheath layer, the adhesive layer body formed by its melt can form patterns corresponding to the inner surface of the braided layer. Thus, during the peeling processing of this braided wire, after removing the braided layer, the surface of the wire body has obvious braided patterns, and the connection contact area between the wire body and the braided layer can be further strengthened through the braided patterns, thereby facilitating the enhancement of the bonding strength between the braided layer and the wire body.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Please refer to Figure 1-2 , in the embodiment of the present utility model, a braided wire in which a wire is adhesively connected to a braided mesh includes a wire body 1 and a braided layer 2. The wire body 1 has a sheath layer 3 on its outer side, and the braided layer 2 is wrapped around the outer side of the sheath layer 3. Among them, an adhesive layer 4 is formed by heating the outer side of the sheath layer 3, so that the sheath layer 3 and the braided layer 2 are adhesively connected to each other through the adhesive layer 4.
[0034] In the technical solution of the present utility model, a braided mesh (braided wire material) is wound around the outer side of the wire body 1 by a braiding machine to form a braided layer 2 acting on the sheath layer 3 on the outer side of the wire body 1. Thus, through the setting of the braided layer 2, the properties of high temperature resistance, aging resistance, friction resistance, etc. of the present braided wire are effectively improved;
[0035] On the basis of not affecting the properties of the wire body 1 and the braided layer 2, by heating the present braided wire, the sheath layer 3 is heated and at least partially melted, so that its outer side is softened by heat to form an adhesive layer 4. Furthermore, through the adhesive layer 4, the sheath layer 3 and the braided layer 2 can be adhesively connected to each other, realizing the bonding and fixing of the braided layer 2 and the sheath layer 3, that is, realizing the bonding and fixing of the braided layer 2 and the wire body 1, ensuring the connection strength between the braided layer 2 and the wire body 1, and thus effectively ensuring the effective use of the present braided wire;
[0036] Specifically, the braided layer 2 can be adhesively fixed to the wire body 1, effectively improving the tensile strength and making the surface smoother, softer, and less likely to produce fluffing and flying filaments. It also ensures that during the cutting process, the braided layer 2 at the cut will not shrink back or become loose, demonstrating the non-opening property of this braided wire, which is more conducive to peeling, welding, and other operations. Moreover, when the wire is curled or stretched, the braided layer 2 on the surface is not easily loosened, making the overall practicality extremely high.
[0037] Among them, it can be understood that the outer sheath layer 3 of conventional wires mainly includes plastic materials such as polyvinyl chloride (PVC), polyethylene (PE), perfluoroethylene propylene (F46), nylon, and polyolefin, as well as rubber materials such as chlorinated polyethylene (CPE), chlorosulfonated polyethylene (CSM), chloroprene rubber, and silicone rubber. Due to its own characteristics, during the heating process, its melt can have viscosity.
[0038] More specifically, in the embodiment of the present utility model, the adhesive layer 4 includes an adhesive layer body 5 and a penetration layer 6 located outside the adhesive layer body 5, and at least part of the penetration layer 6 penetrates into the braided layer 2.
[0039] During the heating process of the sheath layer 3, its melt can penetrate at least partially along the inner surface gap of the braided layer 2 to form the penetration layer 6. Through the setting of the penetration layer 6, the sheath layer 3 and the braided layer 2 can penetrate each other, effectively strengthening the connection contact area between the wire body 1 and the braided layer 2, and further enhancing the adhesive strength between the braided layer 2 and the wire body 1.
[0040] More specifically, in the embodiment of the present utility model, the outer side of the adhesive layer body 5 is formed with patterns corresponding to the braided layer 2.
[0041] During the heating process of the sheath layer 3, the adhesive layer body 5 formed by its melt can form patterns corresponding to the inner surface of the braided layer 2. Thus, during the peeling process of this braided wire, after the braided layer 2 is removed, the surface of the wire body 1 has obvious braided patterns, and the connection contact area between the wire body 1 and the braided layer 2 can be further strengthened through the braided patterns, thereby facilitating the improvement of the adhesive strength between the braided layer 2 and the wire body 1.
[0042] More specifically, in the embodiment of the present utility model, the wire body 1 further includes a metal conductor 7 and an insulating layer 8 covering the metal conductor 7, and the sheath layer 3 covers the outside of the insulating layer 8.
[0043] The metal conductor 7 and its corresponding insulating layer 8 can be provided in one strand or multiple strands according to actual needs.
[0044] More specifically, in the embodiments of the present utility model, the braided layer 2 is one of PU, PE, PP, PET, and PA chemical fiber materials;
[0045] Or the braided layer 2 is one of PU, PE, PP, PET, and PA monofilament materials.
[0046] It can correspond to flat wire or round wire. The braided layer 2 is made of corresponding chemical fiber materials or monofilament materials. Among them, the chemical fiber specification of the braided layer 2 is 50D - 1800D, and the monofilament diameter of the braided layer 2 is 0.05mm - 0.35mm.
[0047] More specifically, in the embodiments of the present utility model, the sheath layer 3 is one of PVC, PU, TPE, TPU, silica gel, and rubber.
[0048] More specifically, in the embodiments of the present utility model, the insulating layer 8 is one of PE, PP, PVC, SR - PVC, TPEE, and PTFE.
[0049] More specifically, in the embodiments of the present utility model, the metal conductor 7 is one of bare copper wire, tin - plated copper wire, bare copper - clad steel wire, tin - plated copper - clad steel wire, enameled copper wire, bare copper - clad aluminum wire, tin - plated copper - clad aluminum wire, and alloy copper wire.
[0050] In the prior art, wires are divided into round wires and flat wires. The braided wire can be heated by an oven (applicable to round wires and flat wires), so as to realize the mutual adhesion between the braided layer 2 and the sheath layer 3;
[0051] Or through a hot - press bonding machine (applicable to flat wires), in a wire - passing manner, to synchronously realize heating and pressing, so as to realize the mutual adhesion between the braided layer 2 and the sheath layer 3, and make the flat wire flatter, that is, the bonding between the wire body 1 and the braided layer 2 is more sufficient.
[0052] In summary, for this braided wire, a metal conductor 7, an insulating layer 8, a sheath layer 3, and a braided layer 2 are sequentially arranged from inside to outside. Its heating principle is: by utilizing the characteristic that the melting points between each layer are inconsistent, on the basis of not affecting the characteristics of the metal conductor 7, the insulating layer 8, and the braided layer 2, the sheath layer 3 is heated and at least partially melted, so as to realize the mutual adhesion between the sheath layer 3 and the braided layer 2;
[0053] The following lists a specific embodiment:
[0054] The metal conductor 7 generally has a melting point of over 600 degrees. The insulating layer 8 is made of PP or PE material with a melting point of about 200 degrees. The sheath layer 3 is made of PVC material with a melting point of about 170 degrees. The braided layer 2 is made of PET chemical fiber or PET monofilament material with a melting point of about 240 degrees. Thus, the heating temperature is controlled within 170 degrees to 200 degrees, enabling at least partial melting of the sheath layer 3 to achieve the mutual adhesion between the sheath layer 3 and the braided layer 2, realizing the bonding and fixation of the wire body 1 and the braided layer 2, and demonstrating the feasibility of the technical solution of the present utility model.
[0055] Furthermore, the adhesion effect between the sheath layer 3 and the braided layer 2 lies in the control of the heating temperature, heating time, and pressure to achieve at least partial melting of the sheath layer 3.
[0056] Furthermore, an isolation layer (not shown) is provided between the insulating layer 8 and the sheath layer 3. That is, a layer of talcum powder can be attached to the surface of the insulating layer 8 to play an isolation role, making it easier for the insulating layer 8 and the sheath layer 3 to separate and less likely to adhere, thus helping to reduce the friction between the wire cores and preventing them from directly contacting and breaking the wire core skin (i.e., the insulating layer 8).
[0057] This braided wire can be applied to the conduction of electronic devices such as computer power output lines, mobile phone chargers, power plug lines, electronic device conduction, connectors, audio - video lines, telescopic charging lines, and in - vehicle charging devices.
[0058] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above - mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any perspective, the embodiments should be regarded as exemplary and non - restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
