Description

Technical Field

[0001] This utility model relates to the field of multi-core cable technology, specifically a multi-core cable. Background Technology

[0002] With the continuous development of electrical equipment and electronic systems, the requirements for the function and performance of cables are increasing, leading to the emergence of multi-core cables. The earliest multi-core cables had a relatively simple structure, mainly consisting of several single-core cables simply combined together and wrapped with an outer sheath.

[0003] The patent publication number "CN220106064U" discloses "a multi-core cable", which includes a protective component. The protective component has a protective layer inside, and a limiting layer is provided on the inner wall of the protective layer. The limiting layer has several wire-holding cavities inside, and an insulation layer is provided inside the several wire-holding cavities. The improved multi-core cable, through the cooperation between the spring and the rubber clamping pad, can buffer the multi-core cable when it is subjected to external pressure and damage during laying or use, avoid damage to the main body of the multi-core cable, reduce the frequency of maintenance and replacement, and thus significantly improve the service life of the multi-core cable by utilizing the cooperation between the protective layer, the limiting layer and the filler rope.

[0004] The aforementioned patent describes a multi-core cable that can be used in various complex environments, solving the problem of bending and cracking that occurs during prolonged use and significantly improving its practicality. However, structurally, this device incorporates protective components, a protective layer, a limiting layer, and a cable-holding cavity, as well as springs and rubber clamping pads. This complex structure may lead to complicated manufacturing processes, increasing production difficulty and cost, and also increasing the cable's weight. Furthermore, if the cable is subjected to uneven external impact, it may experience excessive localized stress, failing to adequately protect the cable.

[0005] Therefore, this utility model provides a multi-core cable to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multi-core cable that solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-core cable, including a protective component, the protective component including a large rubber protective sleeve, the outer surface of a rubber barrier strip being fixedly connected to the inner wall of the large rubber protective sleeve, and a small rubber protective sleeve being fixedly connected to the inner surface of the rubber barrier strip.

[0008] Furthermore, the number of rubber barrier strips is several and they are evenly distributed on the inner wall of the large rubber protective sleeve.

[0009] By adopting the above technical solution, a hollow space is formed between the rubber barrier strips, which provides a certain buffer space for the conductor when the cable is subjected to external impact or compression. The hollow part can be compressed, absorbing and dispersing the external force, reducing the direct transmission of external force to the conductor, thereby protecting the conductor from damage and achieving the beneficial effects of improving cable shock absorption and service life.

[0010] Furthermore, the inner wall of the small rubber protective sleeve is fixedly connected to the outer surface of the rubber barrier strip.

[0011] By adopting the above technical solution, the rubber barrier strip plays a role in isolation and support, connecting the large rubber protective sleeve and the small rubber protective sleeve. At the same time, it can prevent moisture, dust and other impurities from penetrating between different protective sleeves to a certain extent, thereby enhancing the sealing and protection of the cable.

[0012] Furthermore, a rubber core is fixedly connected to the inner surface of the rubber barrier strip.

[0013] By adopting the above technical solution, the rubber core can play a further supporting role, especially for the central part inside the cable, which can maintain the circular structure of the cable and prevent deformation or collapse during use.

[0014] Furthermore, an annular indentation is formed on the outer surface of the large rubber protective sleeve.

[0015] By adopting the above technical solution, the annular indentation increases the friction on the surface of the large rubber protective sleeve, which can better fix the cable during cable laying and use, prevent it from slipping, and improve the convenience and stability of cable installation and use.

[0016] Furthermore, a conductive component is provided between two adjacent rubber barrier strips. The conductive component includes a conductor core, and an insulating layer is sleeved on the outer surface of the conductor core. The outer surface of the insulating layer is fixedly connected to the side surface of the rubber barrier strip.

[0017] By adopting the above technical solution, fewer components mean a corresponding reduction in the costs of raw materials, parts procurement, and processing during the production process. This avoids the problem of high production costs caused by a large number of cables, thereby reducing overall production costs and making the product more price-competitive in the market, achieving the beneficial effect of saving production costs.

[0018] Beneficial effects

[0019] This utility model provides a multi-core cable. Compared with the prior art, it has the following advantages:

[0020] 1. This multi-core cable has a hollow space formed between the rubber barrier strips, which provides a certain buffer space for the conductor when the cable is subjected to external impact or compression. The hollow part can be compressed to absorb and disperse external force, reducing the direct transmission of external force to the conductor, thereby protecting the conductor from damage and achieving the beneficial effects of improving cable shock absorption and service life.

[0021] 2. This multi-core cable, with fewer components, means a reduction in the costs of raw materials, parts procurement, and processing during production. This avoids the problem of higher production costs associated with a larger number of cables, thus lowering overall production costs and making the product more price-competitive in the market, achieving the beneficial effect of saving production costs.

[0028] It should be noted that in the description of the embodiments of this application, the terms "front," "rear," "left," "right," "up," "down," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 4 This application provides a multi-core cable, including a protective component 1. The protective component 1 includes a large rubber protective sleeve 101. The outer surface of a rubber barrier strip 103 is fixedly connected to the inner wall of the large rubber protective sleeve 101. A small rubber protective sleeve 104 is fixedly connected to the inner surface of the rubber barrier strip 103. The number of rubber barrier strips 103 is several and they are evenly distributed on the inner wall of the large rubber protective sleeve 101.

[0031] In this embodiment, the large rubber protective sleeve 101 serves as the outermost layer of protection for the cable, resisting external physical impacts, abrasion, and chemical corrosion, and protecting the internal conductive components 2 and other structures. The rubber barrier strips 103 are evenly distributed on the inner wall of the large rubber protective sleeve 101, dividing the internal space of the large rubber protective sleeve 101 into multiple areas. On the one hand, this enhances the structural strength of the large rubber protective sleeve 101, and on the other hand, it provides support and fixation for the small rubber protective sleeve 104. The small rubber protective sleeve 104 further protects the internal rubber core 105 and conductive components 2, and also helps maintain the stability of the internal structure of the cable.

[0032] Reference Figures 1 to 4 In one aspect of this embodiment, the inner wall of the small rubber protective sleeve 104 is fixedly connected to the outer surface of the rubber barrier strip 103.

[0033] In this embodiment, the inner wall of the small rubber protective sleeve 104 is fixedly connected to the outer surface of the rubber barrier strip 103. This connection method allows the small rubber protective sleeve 104 to be stably installed between the rubber barrier strips 103, forming an integral protective structure. When the cable is subjected to external force, the small rubber protective sleeve 104 can distribute the external force to the entire protective component 1 through its connection with the rubber barrier strip 103, avoiding damage caused by excessive local force.

[0034] Reference Figures 1 to 4 In one aspect of this embodiment, a rubber core 105 is fixedly connected to the inner surface of the rubber barrier strip 103.

[0035] In this embodiment, the rubber core 105 is fixed to the inner surface of the rubber barrier strip 103, and it mainly serves to fill and support. The rubber core 105 fills the center of the cable, making the cable structure more compact, and also provides a stable support center for the surrounding conductive components 2 and protective structures. When the cable is subjected to bending or tensile forces, the rubber core 105 can buffer and disperse these external forces through its own elastic deformation, preventing the internal structure of the cable from shifting or being damaged due to uneven force.

[0036] Reference Figures 1 to 4 In one aspect of this embodiment, an annular groove 102 is formed on the outer surface of the large rubber protective sleeve 101.

[0037] In this embodiment, the annular groove 102 on the outer surface of the large rubber protective sleeve 101 can increase the friction of the cable surface, making the cable easier to fix and less prone to slippage during laying and use. In addition, the annular groove 102 can also enhance the flexibility of the large rubber protective sleeve 101 to a certain extent. When the cable is bent, a certain deformation can occur at the annular groove 102 to adapt to the bending radius of the cable, reduce the stress concentration caused by bending of the large rubber protective sleeve 101, thereby improving the bending performance and service life of the cable.

[0038] Reference Figures 1 to 4 In one aspect of this embodiment, a conductive component 2 is provided between two adjacent rubber barrier strips 103. The conductive component 2 includes a conductor core 201. An insulating layer 202 is sleeved on the outer surface of the conductor core 201. The outer surface of the insulating layer 202 is fixedly connected to the side surface of the rubber barrier strip 103.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] Working principle: The conductor core 201 is the core component of the cable for transmitting current and conducting electrical energy. The insulation layer 202 is sleeved on the outside of the conductor core 201. Its main function is to isolate the conductor core 201 from other conductor cores 201 and the external environment to prevent current leakage and short circuits. The outer surface of the insulation layer 202 is fixedly connected to the side surface of the rubber barrier strip 103, so that the conductive component 2 can be stably installed between two adjacent rubber barrier strips 103. The rubber barrier strip 103 not only provides mechanical support for the conductive component 2, but also further enhances the insulation performance and helps heat dissipation, ensuring that the conductor core 201 can work stably when transmitting current.
