Description

Technical Field

[0001] The utility model relates to the technical field of cloth wires, in particular to an integrally insulated multi-core aramid-reinforced conductor groove cloth wire. Background Art

[0002] Cloth wires are mainly used to transmit power supply from the power source to various electrical equipment or sockets, and are an indispensable part of the power system. According to different characteristics and application scenarios, cloth wires can be divided into various types. For example, PVC-insulated cloth wires are widely used in residential, commercial and industrial buildings due to their good insulation performance and wear resistance; XLPE-insulated cloth wires are suitable for high-temperature and high-pressure environments due to their excellent chemical stability and electrical performance.

[0003] The connection method of the existing cloth wires is relatively cumbersome and does not have a modular design, making the installation and disassembly processes not flexible and convenient enough. Moreover, the materials that the cloth wires may use have poor high-temperature resistance, resulting in a decline in electrical insulation performance in high-temperature environments and posing potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide an integrally insulated multi-core aramid-reinforced conductor groove cloth wire to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an integrally insulated multi-core aramid-reinforced conductor groove cloth wire, including a plurality of connection seats. A groove is opened on the left side of the connection seat, and a block is fixedly arranged on the right side of the connection seat. The block is clamped in the groove. A connection protection ring is fixedly arranged on the top of the connection seat. A cloth wire body passes through between the connection seat and the connection protection ring. Inside the cloth wire body, a conductor core wire, an inner insulation layer, an aramid reinforcement layer, an outer insulation layer, a shielding braid layer, a flame retardant layer, a self-repairing insulation layer, and a bio-based sheath are sequentially arranged from inside to outside.

[0006] A limiting hole is opened on the connection seat.

[0007] The inner insulation layer is made of a polyimide nano-composite material, and the outer insulation layer is made of a new thermoplastic polyurethane elastomer material.

[0008] The flame retardant layer is made of a polymer material containing a new halogen-free flame retardant.

[0009] The bio-based sheath is made of renewable resources.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. Excellent high-temperature resistance and electrical insulation performance: Since the inner insulating layer uses a polyimide nanocomposite material, this material can provide excellent high-temperature resistance, ensuring that the wire can still maintain stable electrical insulation performance in high-temperature environments. This is crucial for equipment that needs to operate in high-temperature or complex environments.

[0012] 2. Outstanding physical properties: The outer insulating layer uses a new type of thermoplastic polyurethane elastomer material, which not only has good elasticity but also excellent wear resistance, oil resistance, and cold resistance. This means that the wire can maintain good performance in harsh environments, extending its service life.

[0013] 3. Effective electromagnetic shielding: The shielding braid layer is made of fine copper wires or silver wires woven together, which can effectively reduce electromagnetic interference and improve the stability of the wire in complex electromagnetic environments.

[0014] 4. High flame retardancy: The flame-retardant layer uses a polymer material containing a new type of halogen-free flame retardant, which not only improves the safety performance of the wire but also meets environmental requirements, reducing the fire risk.

[0015] 5. Self-healing function: The design of the self-healing insulating layer is a major highlight of this technology. When the insulating layer has minor damage, the microcapsule repair agent will automatically fill the cracks and restore the insulating performance. This function greatly reduces the safety hazards caused by insulation layer damage.

[0016] 6. Environmentally friendly and sustainable: The bio-based sheath is made of renewable resources, which is not only environmentally friendly and degradable but also has good durability. This meets the current urgent needs for sustainable development and environmental protection.

[0017] 7. Modular design: The design of the connection seat and the clamping block makes the wire easy to install and disassemble, improving the flexibility and convenience of wiring. At the same time, the fixing method through the limit hole and the bolt also enhances the stability and safety of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: an integrally insulated multi-core aramid-reinforced conductor card slot cloth wire, including a plurality of connecting seats 1. A card slot 3 is opened on the left side of the connecting seat 1, and a card block 6 is fixedly arranged on the right side of the connecting seat 1. The card block 6 is clamped in the card slot 3. A connecting protection ring 4 is fixedly arranged on the top of the connecting seat 1. A cloth wire body 5 passes through between the connecting seat 1 and the connecting protection ring 4. Inside the cloth wire body 5, there are successively arranged a conductor core wire 7, an inner insulation layer 8, an aramid reinforcement layer 9, an outer insulation layer 10, a shielding braid layer 11, a flame retardant layer 12, a self-healing insulation layer 13, and a bio-based sheath 14 from the inside to the outside.

[0025] A limiting hole 2 is opened on the connecting seat 1. The limiting hole can limit the connecting block through bolts and fix the connecting seat 1 to the installation position.

[0026] The inner insulation layer 8 is made of a polyimide nanocomposite material, providing excellent high-temperature resistance and electrical insulation performance. The outer insulation layer 10 is made of a new thermoplastic polyurethane elastomer material, which not only has good elasticity but also excellent wear resistance, oil resistance, and cold resistance. The shielding braid layer 11 is woven with fine copper wires or silver wires to form an effective electromagnetic shielding layer to reduce electromagnetic interference.

[0027] The flame retardant layer 12 is made of a polymer material containing a new halogen-free flame retardant.

[0028] The self-healing insulation layer 13 adopts the self-healing material technology that has emerged in recent years. Microcapsule repair agents are added to the insulation layer. When the insulation layer has minor damage, the repair agents will automatically flow out and fill the cracks to restore the insulation performance. The bio-based sheath 14 is made of a bio-based plastic sheath made of renewable resources (such as corn starch), which is not only environmentally friendly and degradable but also has good durability.
