Abstract

This utility model relates to a household electronic wire, comprising a wire body and a circumferentially arranged TPU reinforcing strip structure. The TPU reinforcing strip is arranged radially along the wire body, with its end extending beyond the wire body to form a flared structure. The wire body, from the outside to the inside, includes an outer sheath layer, an insulation core layer, and an elastic buffer layer. The wire core is made of twisted copper alloy wire. The TPU reinforcing strip mechanically engages with the outer sheath layer through mounting pads, forming a multi-dimensional support system that significantly improves tensile and torsional resistance, effectively disperses external stress, and suppresses structural deformation. The flared design enables a smooth transition with connecting components, reducing the risk of stress concentration at the interface. During wiring, the TPU reinforcing strip and insulating tape work together to provide additional support and fixation at the connection point through a tight fit. This structure ensures connection reliability while forming an elastic buffer interface, possessing both vibration resistance and long-term stability.

Description

Technical Field

[0001] This utility model relates to the field of electronic wires, specifically to a household electronic wire. Background Technology

[0002] As a key component for power transmission and signal transmission in the home environment, the performance and stability of household electrical wiring directly affect the safety and lifespan of electrical appliances. With the increasing popularity of smart home devices, household electrical wiring needs to withstand complex operating conditions such as frequent bending, twisting, and external environmental vibrations, while also ensuring ease of installation and long-term reliability. This places higher demands on the structural design of the wiring.

[0003] Traditional household electronic wires typically use a single-material sheath or a simple braided reinforcement structure, which has significant limitations in terms of tensile and torsional resistance. When the wire is subjected to radial tension or torsional stress, the sheath layer and the internal conductor are prone to relative displacement, leading to wire deformation or even breakage. Connections often rely on adhesive bonding or direct nesting for fixation, which can easily lead to structural loosening due to material creep or vibration impact during long-term use. Furthermore, vibration energy can be directly transferred through the rigid connection interface, exacerbating the risk of interface fatigue. In addition, the transition area between the end of traditional wires and the connecting components is often at a right angle, resulting in a significant stress concentration effect. The lack of effective auxiliary fixing structures during wiring makes the connection points prone to poor contact or loosening due to external pulling or insufficient insulation tape wrapping. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide a household electronic wire that solves the aforementioned technical problems.

[0005] The objective of this utility model is achieved through the following means:

[0006] A household electronic wire includes a wire body and TPU reinforcing strips. The TPU reinforcing strips are radially mounted on the outer surface of the wire body, and there are no fewer than three sets of TPU reinforcing strips arranged circumferentially around the outer surface of the wire body. The ends of the TPU reinforcing strips extend beyond the ends of the wire body and are flared out. The outer ring of the wire body is an outer sheath layer. An insulating main body layer is lined inside the outer sheath layer. An elastic buffer layer is also attached inside the insulating main body layer. A wire core is provided inside the insulating main body layer. The wire core is made of high-purity copper alloy wire twisted together. The TPU reinforcing strips are evenly distributed outside the outer sheath layer, and the TPU reinforcing strips are connected to the outer sheath layer by mounting pads.

[0007] Preferably, the inner cavity of the elastic buffer layer is filled with fiber filling material, and the wire core is inserted into the inside of the fiber filling material. The fiber filling material is made of polyester fiber. Polyester fiber has a stable structure and is not easy to collapse after filling, which improves the stability of the wire core installation.

[0008] Preferably, the mounting pads are spaced 3-5cm apart, and the mounting pads, TPU reinforcing strips, and outer sheath are all bonded together. The inner wall of the TPU reinforcing strip is evenly covered with mounting pads, and the mounting pads are all installed on the surface of the outer sheath. The TPU reinforcing strip is installed on the surface of the outer sheath by means of bonding.

[0009] Preferably, the TPU reinforcing strip is lined with steel wire, and the TPU reinforcing strip protrudes outward with the mounting pad as the connection point, so that when the electronic wire is wired, the TPU reinforcing strip and the protective layer can be avoided being cut together.

[0010] Preferably, the inner layer of the outer sheath is an environmentally friendly flame-retardant outer skin, and the outer surface of the environmentally friendly flame-retardant outer skin is covered with a wear-resistant layer. The outer sheath is composed of an environmentally friendly flame-retardant outer skin and a wear-resistant layer. The environmentally friendly flame-retardant outer skin is composed of a halogen-free polymer substrate, an inorganic flame retardant, and a synergist, and the wear-resistant layer is an epoxy resin-based coating.

[0011] The beneficial effects of this utility model are:

[0012] This household electronic wire uses a multi-group arrangement of TPU reinforcing strips in the circumferential direction to form a multi-dimensional support system in the radial direction of the wire, which significantly improves tensile and torsional resistance, effectively disperses external stress to prevent wire deformation or breakage. The PU reinforcing strips and the outer sheath layer are mechanically engaged through mounting pads, forming an elastic buffer interface while ensuring connection reliability, effectively suppressing vibration transmission and reducing the risk of structural loosening during long-term use.

[0013] The flared end design allows for a smooth transition between the reinforcing strip and the connecting components, reducing the risk of stress concentration at the interface. Furthermore, during wiring, the presence of the TPU reinforcing strip ensures that when insulating tape is used for wrapping, the tape adheres tightly to the TPU reinforcing strip and the wiring point, providing additional support and fixation, thereby improving the stability of the wiring.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In this embodiment, refer to Figures 1-4 The present invention relates to a household electronic wire, comprising a wire body 1 and TPU reinforcing strips 2. The TPU reinforcing strips 2 are radially mounted on the outer surface of the wire body 1, and there are no fewer than three sets of TPU reinforcing strips 2, which are circumferentially arranged around the outer surface of the wire body 1. The ends of the TPU reinforcing strips 2 extend out of the ends of the wire body 1 and are in the shape of a trumpet. The outer ring of the wire body 1 is an outer sheath layer 101. An insulating main body layer 102 is lined on the inner side of the outer sheath layer 101. An elastic buffer layer 103 is also attached inside the insulating main body layer 102. A wire core 105 is provided inside the insulating main body layer 103. The wire core 105 is made of high-purity copper alloy wire twisted together. The TPU reinforcing strips 2 are evenly distributed on the outside of the outer sheath layer 101, and the TPU reinforcing strips 2 and the outer sheath layer 101 are connected by mounting pads 3.

[0021] The high-purity copper alloy wire stranded structure used in the core 105 increases the cross-sectional area of ​​the conductor, thereby reducing resistance, heat generation, and voltage instability, ensuring the normal operation of electrical equipment. Furthermore, the elastic buffer layer 102 enhances the flexibility of the wire, allowing it to withstand frequent bending and folding, significantly extending its service life. Simultaneously, the outer sheath layer 101 prevents the spread of fire in the event of a fire, further improving safety. This allows the wire to be used for extended periods in high-temperature environments without insulation problems, effectively avoiding leakage hazards and enhancing safety in use.

[0022] During wiring, the TPU reinforcing strip 2 can be placed at the wiring point. When insulating tape is used for wrapping, the insulating tape will tightly adhere the TPU reinforcing strip 2 to the wiring point, allowing the TPU reinforcing strip 2 to make full contact with the wiring point, thereby providing additional support and fixation for the wiring point and improving the stability of the wiring point.

[0023] The insulating main layer 102 is composed of a high-temperature resistant polymer matrix and nano-ceramic particles, the elastic buffer layer 103 is made of a high-elasticity rubber matrix, and the fiber filling material 104 is made of polyester fiber.

[0024] The inner cavity of the elastic buffer layer 103 is filled with fiber filling material 104, and the wire core 105 is inserted into the fiber filling material 104. The fiber filling material 104 is made of polyester fiber. The polyester fiber structure is stable and does not easily collapse after filling, which improves the stability of the installation of the wire core 105.

[0025] The spacing between the mounting pads 3 is 3-5cm, and the mounting pads 3 are bonded to the TPU reinforcing strip 2 and the outer sheath layer 101. The mounting pads 3 are evenly distributed on the inner wall of the TPU reinforcing strip 2. The mounting pads 3 are all installed on the surface of the outer sheath layer 101. The mounting pads 3 are bonded to the surface of the outer sheath layer 101 to the TPU reinforcing strip 2.

[0026] The TPU reinforcing strip 2 is lined with steel wire. The TPU reinforcing strip 2 protrudes outward with the mounting pad 3 as the connection point. That is, in the working state, each TPU reinforcing strip 2 segment separated by the mounting pad 3 is in a tightened state, i.e., protruding outward. When the electronic wire is cut for wiring, the outer reinforcing strip will naturally open up to facilitate wiring operations.

[0027] The inner layer of the outer sheath 101 is an environmentally friendly flame-retardant outer skin 1011. The outer surface of the environmentally friendly flame-retardant outer skin 1011 is covered with a wear-resistant layer 1012. The outer sheath 101 is composed of the environmentally friendly flame-retardant outer skin 1011 and the wear-resistant layer 1012. The environmentally friendly flame-retardant outer skin 1011 is composed of a halogen-free polymer substrate, an inorganic flame retardant and a synergist. The wear-resistant layer 1012 is an epoxy resin-based coating.

[0028] This embodiment of a household electronic wire includes an outer sheath 101 composed of an environmentally friendly flame-retardant outer sheath 1011 and a wear-resistant layer 1012. The environmentally friendly flame-retardant outer sheath 1011 is composed of a halogen-free polymer substrate, an inorganic flame retardant, and a synergist.

The inner wall of the outer sheath 101 is provided with an insulating main layer 102, which is composed of a high-temperature resistant polymer matrix and nano-ceramic particles. The inner wall of the insulating main layer 102 is provided with an elastic buffer layer 103, which is made of a highly elastic rubber matrix. Its inner cavity is filled with a fiber filling material 104 made of polyester fiber. The wire core 105 is made of high-purity copper alloy wire twisted together and inserted inside the fiber filling material 104. The outer sheath 101 is uniformly covered with TPU reinforcing strips 2, and the inner wall of the TPU reinforcing strips 2 is uniformly covered with mounting pads 3. The mounting pads 3 are used to install the TPU reinforcing strips 2 onto the surface of the outer sheath 101 by adhesive bonding.

Under this structure, the twisted structure of the wire core 105 reduces resistance, heat generation and voltage instability, the elastic buffer layer 103 enhances flexibility, and the outer sheath 101 prevents the spread of fire and improves safety in case of fire. When wiring, the TPU reinforcing strips 2 are wrapped tightly with insulating tape to the wiring point, providing additional support and fixation and improving the stability of the wiring point.
