AI Technical Summary
Existing power cables lack pressure-proof structures, which are prone to deformation, damage or breaking of cable cores when subjected to pressure or impact, affecting their performance.
A composite impact-resistant flexible cable is designed, adopting a double impact-proof layer structure inside and outside. The inner impact-proof layer is in a diamond shape and the outer impact-proof layer is a thermoplastic elastomer. The impact force is dispersed through buffer holes, buffer strips and buffer grooves.
Through the design of double impact-proof layers inside and outside, when the cable is impacted, the external impact-proof layer serves as the first layer of buffering, and the internal impact-proof layer further disperses the impact force through the buffer holes and grooves, which significantly improves the impact resistance of the cable.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a composite impact-resistant flexible cable. Background Art
[0002] With the continuous advancement of modernization, cables are increasingly used in buildings. Power cables are made of multiple mutually insulated cable cores and an outer insulating protective layer. Their function is to transmit electricity from one place to another. In the actual laying process of power cables, power cables are very likely to collide with other objects or be squeezed by other objects. The existing power cables on the market lack a certain anti-pressure structure, which can easily cause the cable core of the power cable to deform, damage or break due to pressure or impact, making it difficult to ensure the performance of the power cable.
[0003] For multi-core power cables, when under pressure or impact, multiple cable cores may be damaged due to mutual squeezing, resulting in a short circuit, thereby affecting the normal use of the power cable. Therefore, it is necessary to design a high-strength and impact-resistant composite cable. Utility Model Content
[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.
[0005] The composite impact-resistant flexible cable comprises an inner core, an inner impact-proof layer is arranged on the outside of the inner core in sequence, the inner impact-proof layer is arranged in a diamond shape, and each diamond edge of the inner impact-proof layer is covered with an outer impact-proof layer; buffer holes are arranged in an array between each diamond edge of the inner impact-proof layer and the inner core, buffer strips are arranged in the buffer holes, and buffer grooves are arranged between adjacent buffer holes; the inner impact-proof layer is in a concave arc shape, the outer impact-proof layer is made of thermoplastic elastomer, and the outer impact-proof layer is filled in the concave arc.
[0006] Furthermore, the inner anti-impact layer is made of polyethylene material.
[0007] Furthermore, the buffer groove is configured to be in a semi-arc shape.
[0008] Furthermore, the inner impact-proof layer is configured to be in a four-sided shape.
[0009] Furthermore, the connection between adjacent diamond edges of the inner impact-proof layer is an arc-shaped connection.
[0010] The beneficial effect of the utility model is that the inner and outer anti-impact layers are designed in a double manner. When the cable is hit, the outer anti-impact property is first used as a buffer. On the other hand, during the extrusion process, the buffer holes and buffer grooves are used to further disperse the impact force, thereby improving the impact resistance of the cable.

Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0016] See also Figures 1-2 The utility model comprises an inner core 1, an inner anti-impact layer 2 is sequentially arranged outside the inner core 1, the inner anti-impact layer 2 is arranged in a rhombus shape, and each rhombus edge of the inner anti-impact layer 2 is covered with an outer anti-impact layer 3; buffer holes 4 are arranged in an array between each rhombus edge of the inner anti-impact layer 2 and the inner core 1, buffer strips 5 are arranged in the buffer holes 4, and buffer grooves 6 are arranged between adjacent buffer holes 4; the inner anti-impact layer 2 is in a concave arc shape, the outer anti-impact layer 3 is made of thermoplastic elastomer, and the outer anti-impact layer 3 is filled in the concave arc.
[0017] This technical solution mainly utilizes the characteristics of structure and materials to improve the impact resistance and flexibility of the cable.
[0018] From the structural design point of view, an inner impact-proof layer 2 is firstly provided outside the inner core 1. For the inner impact-proof layer 2, the inner impact-proof layer 2 is set in a diamond shape, and a buffer hole 4 is arranged in an array between each diamond edge of the inner impact-proof layer 2 and the inner core 1. A buffer card strip 5 is arranged in the buffer hole 4, and a buffer groove 6 is arranged between adjacent buffer holes 4. The design mainly realizes buffering and impact prevention through the buffer hole 4 and the buffer groove 6 by means of air holes. The buffer holes 4 are assembled in an array form between each diamond edge of the inner impact-proof layer 2 and the inner core 1, and a buffer groove 6 is arranged between adjacent buffer holes 4, that is, During the extrusion impact process, no matter the buffer hole 4 is subjected to a large extrusion pressure or the buffer groove 6 is subjected to a large extrusion pressure, the forces will be dispersed against each other, and the buffer groove 6 is set in a semi-arc shape. When the buffer groove 6 is subjected to force, the dispersion force is dispersed diffusion, and for the buffer hole 4, a buffer strip 5 is set therein, that is, when the buffer hole 4 is subjected to force, the buffer strip 5 will have a reaction force as a dispersion of the external extrusion force, thereby achieving anti-impact force. Furthermore, each diamond edge of the inner anti-impact layer 2 is covered with an outer anti-impact layer 3, and the outer anti-impact layer 3 further achieves external extrusion impact.
[0019] From the perspective of material design, the outer impact-proof layer 3 is made of thermoplastic elastomer, which mainly utilizes the elasticity, flexibility, and resistance to corrosion or dissolution of thermoplastic elastomer itself, and is set on the outermost layer, so that it can adapt to a wide range of environmental scenarios. The inner impact-proof layer 2 is made of polyethylene material, specifically high-density polyethylene material, to obtain good wear resistance and impact resistance to protect the inner core 1 part.
[0020] The inner impact-proof layer 2 is configured to be a four-sided rhombus shape, and the adjacent rhombus edges of the inner impact-proof layer 2 are connected in an arc shape. The arc shape of the rhombus edges ensures the dispersion of force at the outer surface when subjected to extrusion impact.
