Impact-resistant cable

Abstract

The invention discloses an anti-impact cable which comprises a cable core, a supporting structure which plays a role in damping and anti-extrusion protection is attached to the outer wall of the cable core, the cable core and the supporting structure are coated with an insulating layer, and the insulating layer is sleeved with a buffering layer which provides additional buffering and damping protection. According to the anti-impact cable, in order to further enhance the anti-impact performance of the cable, a supporting structure is further introduced. When the cable is impacted, the structure can uniformly transmit impact force into the cavity, and then the impact force acts on the built-in damping ball. And the shock absorption balls continuously jump and impact in the cavity, so that vibration caused by impact is effectively counteracted, and the cable is protected from being damaged. The design not only improves the durability of the cable, but also ensures the reliability and stability of the cable in long-term use.

Description

Technical Field

[0001] The present invention relates to the technical field of cables, and particularly to an impact-resistant cable. Background Art

[0002] A cable is a conductor used to transmit electricity or information, usually consisting of one or more mutually insulated conductors and an outer insulating protective layer. Cables are widely used in the fields of electricity, communication, industrial automation, etc., and are an indispensable part of modern electrical systems.

[0003] With the increasingly complex application environment of cables, higher requirements are put forward for the impact resistance of cables. In some harsh working environments, such as subway transportation, mines, construction sites, etc., cables are often subject to external force impacts, which may cause damage to the conductors inside the cables, thereby affecting the normal transmission function of the cables and even leading to safety accidents.

[0004] The traditional cable structure has obvious deficiencies in terms of impact resistance. For example, although the outer sheath material of conventional cables has certain insulation and protection functions, it is easily damaged when subjected to large external force impacts, resulting in the exposure of the internal conductors, thereby reducing the service life of the cables. In addition, the conductors inside the cables are also prone to deformation or fracture when subjected to impacts, further affecting the electrical performance of the cables.

[0005] In view of the above problems, there is an urgent need to innovate and design on the basis of the original cables. Summary of the Invention

[0006] The technical solution of the present invention provides a solution for an impact-resistant cable that is significantly different from the prior art to solve the problems raised in the above background art for the technical problem of the overly single solution of the prior art solution.

[0007] To achieve the above object, the present invention provides the following technical solution: an impact-resistant cable, including a cable core, a support structure for shock absorption and anti-extrusion protection is attached to the outer wall of the cable core, and an insulating layer is wrapped around the cable core and the support structure. An additional buffer shock-absorbing protection layer is provided outside the insulating layer, and an additional mechanical protection armor side is provided outside the buffer layer, and a corrosion-resistant outer layer is provided outside the armor side.

[0008] Preferably, the support structure includes a support sleeve, a cavity, and shock-absorbing balls. The support sleeves and the cable core are arranged alternately in a ring shape. A cavity is opened in each support sleeve, and each cavity is divided into shock-absorbing chambers similar to bamboo joints, and a number of shock-absorbing balls for colliding with each other to offset impacts are provided in each shock-absorbing chamber.

[0009] Preferably, the insulating layer is cross-linked polyethylene with excellent thermal stability, electrical properties, and mechanical properties.

[0010] Preferably, the buffer layer is provided with a hollow X-shaped structure, and the buffer layer is ethylene propylene rubber with ozone resistance, heat resistance, moisture resistance, low temperature flexibility and electrical insulation properties.

[0011] Preferably, the armored side is woven from copper wire and aluminum wire, so as to provide mechanical impact resistance and play a role in shielding and anti-interference.

[0012] Preferably, the outer sheath is made of chloroprene rubber material with good oil resistance, heat resistance, aging resistance and chemical corrosion resistance.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: for this impact-resistant cable, cross-linked polyethylene is selected as the material of the insulating layer. We have not only significantly improved the thermal stability and electrical performance of the cable, but also greatly enhanced its mechanical properties. This material innovation enables the cable to show higher tolerance when facing impacts and bends, thus standing out in harsh working environments.

[0014] In addition, we have innovatively designed the buffer layer with a hollow X-shaped structure. This design endows the cable with a shock-absorbing effect similar to that of a cushioned shoe, further enhancing the cable's protection ability when being impacted. This unique buffer structure can effectively disperse and absorb external impact forces, reducing damage to the internal structure of the cable.

[0015] In order to further enhance the impact resistance of the cable, we have also introduced a support structure. When the cable is impacted, this structure can evenly transfer the impact force into the cavity, and then act on the built-in shock-absorbing balls. The continuous bouncing and impact of the shock-absorbing balls in the cavity effectively counteract the vibration brought by the impact, thus protecting the cable from damage. This design not only improves the durability of the cable, but also ensures its reliability and stability during long-term use. Description of the Drawings
