Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, specifically to a silicone-coated shielded wire and cable. Background Technology

[0002] Wires and cables are wire products used to transmit electrical energy, information, and realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also simply referred to as cables. In a narrow sense, cables refer to insulated cables, which can be defined as: an assembly consisting of one or more insulated conductors, and their respective possible coverings, overall protective layers, and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] Existing silicone-coated shielded wires and cables lack orderly constraint on the internal cable cores, making them prone to tangling and compression. This not only increases the difficulty of cable management during installation but may also cause wear on the insulation layer due to friction, affecting shielding performance and service life. At the same time, the traditional structure has insufficient buffer protection design, making the internal cable cores susceptible to damage when subjected to external impacts or frequent bending. Furthermore, the overall structure has limited anti-interference capabilities, making it difficult to meet the signal transmission stability requirements of high-precision equipment, and its applicability needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a silicone-coated shielded wire and cable to overcome the aforementioned technical problems in related existing technologies.

[0005] A silicone-coated shielded wire and cable includes a silicone sleeve, a cable management soft rubber plate, and cable cores. A buffer layer is fixedly connected to the inner wall of the silicone sleeve, and a shielding layer is fixedly connected to the inner wall of the buffer layer. Foam filler is filled between the inner wall of the shielding layer and the outer wall of the cable management soft rubber plate. Multiple core slots are formed inside the cable management soft rubber plate, and the cable cores are embedded in these slots. A second buffer layer is fixedly connected to the inner wall of each core slot. A filling groove is formed at the edge of the cable management soft rubber plate, and the filling groove is filled with foam filler. An installation groove is formed in the middle of the cable management soft rubber plate, and multiple cable management holes are formed through the inner wall of the installation groove.

[0006] Preferably, the first buffer layer is made of silicone sponge material, and the first buffer layer is bonded and fixed to the silicone sleeve and the shielding layer by a hot melt adhesive layer.

[0007] Preferably, the shielding layer is a metal woven mesh structure, woven from tin-plated copper wire or aluminum-magnesium alloy wire.

[0008] Preferably, the cable management soft rubber board is integrally molded from flame-retardant silicone material.

[0009] Preferably, both the first foam filler and the second foam filler are polyurethane foam materials.

[0010] Preferably, the second buffer layer is a nitrile rubber microbubble layer, and it is integrally formed with the inner wall of the core groove through injection molding.

[0011] Preferably, the cable core includes a conductor and an insulating layer covering the outside of the conductor. The conductor is made of multiple strands of nickel-plated copper wire twisted together, and the insulating layer is made of PFA material.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a silicone-coated shielded wire and cable. By incorporating a flexible cable management board, wire core grooves, and cable management holes, the flexible cable management board is integrally molded from flame-retardant silicone material, possessing excellent flame-retardant properties. Combined with the wire core grooves that separate the cable cores, it effectively prevents the spread of fire caused by localized overheating or short circuits, thus improving the fire safety level of the wire and cable during use. Simultaneously, the cable management holes are designed to accommodate auxiliary fasteners of different specifications, allowing the wire and cable to be flexibly adjusted in their fixing positions according to actual needs in complex wiring environments. This enhances the flexibility and adaptability of the wiring, reducing installation difficulty caused by wiring limitations.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1-4 As shown, this utility model provides a silicone-coated shielded wire and cable, including a silicone sleeve 1, a cable management soft rubber plate 2, and a cable core 3. A buffer layer 101 is fixedly connected to the inner side wall of the silicone sleeve 1, and a shielding layer 102 is fixedly connected to the inner side wall of the buffer layer 101. Foam filler 103 is filled between the inner side wall of the shielding layer 102 and the outer side wall of the cable management soft rubber plate 2. Multiple core grooves 203 are opened inside the cable management soft rubber plate 2, and the cable core 3 is embedded in the core groove 203. A second buffer layer 202 is fixedly connected to the inner side wall of the core groove 203. A filling groove 204 is opened at the edge of the cable management soft rubber plate 2, and a second foam filler 4 is filled in the filling groove 204. An installation groove 201 is opened in the middle of the cable management soft rubber plate 2, and multiple cable management holes 5 are opened through the inner side wall of the installation groove 201.

[0023] In this embodiment, the multiple core grooves 203 of the cable management board 2 physically isolate the cable cores 3, preventing the insulation layer from being worn due to the entanglement and friction of multiple cable cores. The buffer layer 202 inside the core groove 203 absorbs the local stress generated by the cable cores when bending and moving through micro-elastic deformation, reducing the risk of conductor fatigue fracture. In particular, it provides targeted protection for multi-strand stranded nickel-plated copper wire conductors, ensuring stable conductivity. All layers of materials have high and low temperature resistance and aging resistance. The elastic material design of the buffer layer and filler allows the cable to maintain structural integrity under frequent bending and twisting scenarios, adapting to various complex working conditions.

[0024] Example 2

[0025] like Figure 1-4As shown, in one embodiment, the buffer layer 101 is made of silicone sponge material, and the buffer layer 101, silicone sleeve 1, and shielding layer 102 are all bonded and fixed by hot melt adhesive. The shielding layer 102 is a metal braided mesh structure, made of tin-plated copper wire or aluminum-magnesium alloy wire. The cable management soft rubber board 2 is integrally molded with flame-retardant silicone material. The foam filler 103 and foam filler 204 are both polyurethane foam materials. The buffer layer 202 is a nitrile rubber microbubble layer, and is integrally molded with the inner sidewall of the core groove 203 by injection molding. The cable core 3 includes a conductor and an insulation layer covering the outside of the conductor. The conductor is made of multiple strands of nickel-plated copper wire twisted together, and the insulation layer is made of PFA material.

[0026] In this embodiment, the silicone sponge material has good elasticity and cushioning properties, effectively absorbing external impacts. The hot melt adhesive layer ensures a firm connection between the cushioning layer, the silicone sleeve, and the shielding layer, preventing detachment. Tin-plated copper wire has excellent conductivity and oxidation resistance, while aluminum-magnesium alloy wire offers good shielding and lightweight characteristics. The metal braided mesh structure effectively blocks external electromagnetic interference, ensuring the stability of the cable core's signal transmission. The flame-retardant silicone material has excellent flame-retardant properties, reducing the risk of fire. The one-piece molding process makes the cable management soft rubber board structure stable and has good overall integrity, while also possessing a certain degree of flexibility, facilitating cable bending and installation. The cable is constructed with lightweight polyurethane foam, which provides excellent filling and cushioning properties. This fills the gaps between the shielding layer and the cable management board, as well as within the filling grooves, reducing internal structural movement and improving overall stability. The nitrile rubber microbubble layer offers good wear resistance and elasticity, reducing friction between the cable core and the core groove. Integrated injection molding ensures a tight bond between the cushioning layer and the core groove, enhancing protection for the cable core. The conductor, composed of multiple strands of nickel-plated copper wire, exhibits good flexibility and conductivity, while the nickel plating improves corrosion resistance. PFA material provides excellent high-temperature resistance and insulation, ensuring the safe and stable operation of the cable core.

[0027] The working principle of this silicone-coated shielded wire and cable will be explained in detail below:

[0028] During use, the silicone sleeve 1 provides outer protection, the buffer layer 101 absorbs the impact of external forces on the whole; the shielding layer 102 blocks external electromagnetic interference, ensuring the stability of the signal transmission of the cable core 3; the foam filler 103 and the foam filler 2 4 fill the gaps and reduce the shaking of the internal structure; the core groove 203 on the cable management board 2 positions and organizes the cable core 3, and the buffer layer 202 reduces the friction between the cable core 3 and the core groove 203; the mounting groove 201 and the cable management hole 5 facilitate the installation and management of the cable, improving the efficiency of installation and disassembly.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
