Description

Technical Field

[0001] The utility model relates to the technical field of composite cables, in particular to a composite cable that is resistant to bending. Background Art

[0002] Composite cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. They are especially used to reduce consumption losses. They are transportation and distribution cables made of composite materials. Composite materials have the advantages of high strength, good designability, no creep, corrosion resistance and easy use. In terms of fire resistance, the oxygen index of the developed composite cable bracket is greater than or equal to 70%, which meets the safety requirements of fire resistance, low smoke, halogen-free and non-toxic.

[0003] During use, the composite cable may be bent multiple times or for a long time, and the existing composite cables are often single-structured and cannot withstand bending, which may cause the inner core to break or be damaged, thereby causing signal damage. Therefore, a bending-resistant composite cable is proposed. Utility Model Content

[0004] The utility model aims to provide a composite cable that is resistant to bending, thereby solving the problem that the existing composite cables are often not resistant to bending due to their single structure.

[0005] The utility model is implemented as follows: a bending-resistant composite cable comprises a composite cable body, wherein the composite cable body is provided with: an outer sheath, an insulating layer, a sealing member, a protective bracket, a cable and a metal reinforcement member in sequence from the outside to the inside;

[0006] There are several sealing members, which are evenly distributed on the protective bracket;

[0007] Wherein, the cable is arranged inside the protective bracket.

[0008] A further technical solution of the utility model is: the protective bracket comprises: a round tube, a reinforcing rib arranged on the round tube, an anti-pressure layer arranged on the reinforcing rib and an installation port arranged on the anti-pressure layer, and the material of the protective bracket can be glass fiber.

[0009] A further technical solution of the utility model is: there are a plurality of reinforcing ribs, which are circumferentially distributed on the circular tube.

[0010] A further technical solution of the utility model is: a protection compartment is formed between two adjacent reinforcing ribs, and the cable is arranged inside the protection bracket through the protection compartment.

[0011] A further technical solution of the utility model is: the sealing member is arranged on the protective bracket through the installation opening, and the material of the sealing member can be epoxy resin.

[0012] A further technical solution of the utility model is: the metal reinforcement is arranged inside the round tube, and the diameter of the metal reinforcement is matched with the inner diameter of the round tube, and the metal reinforcement can be made of brass.

[0013] Beneficial effects of the utility model: Compared with traditional composite cables, the utility model includes three layers of protection, namely, an outer sheath, an insulating layer and a protective bracket. While ensuring wear resistance and insulation, it can also take into account bending resistance. At the same time, metal reinforcements are provided inside the protective bracket to improve the strength of the composite cable, which can effectively prevent the inner core from breaking or being damaged, thereby causing signal damage.

[0020] Figure 1-Figure 3 The main structural components of a bending-resistant composite cable are shown. The bending-resistant composite cable includes a composite cable body 8. The composite cable body 8 is provided with: an outer sheath 1, an insulating layer 2, a sealing member 3, a protective bracket 4, a cable 5 and a metal reinforcement member 6 in sequence from the outside to the inside;

[0021] There are several seals 3, which are evenly distributed on the protective bracket 4;

[0022] The cable 5 is arranged inside the protection bracket 4 .

[0023] like Figure 3 As shown, the protective bracket 4 is the main anti-bending component of the bending-resistant composite cable. The material of the protective bracket 4 can be glass fiber to increase the overall strength of the composite cable. The protective bracket 4 includes: a round tube 43, a reinforcing rib 42 arranged on the round tube 43, an anti-pressure layer 41 arranged on the reinforcing rib 42, and an installation port 44 arranged on the anti-pressure layer 41.

[0024] There are several reinforcing ribs 42, which are circumferentially distributed on the round tube 43. The main function of the reinforcing ribs 42 is to support and connect. While connecting the pressure-proof layer 41, it can also play a supporting role to prevent the external force from directly acting on the cable 5 when the composite cable body 8 is compressed, thereby causing damage to the cable 5.

[0025] like Figure 1 As shown, a protective compartment 7 is formed between two adjacent reinforcing ribs 42, and the cable 4 is arranged inside the protective bracket 4 through the protective compartment 7. The cable 5 in the protective compartment 7 is between the round tube 43 and the pressure-proof layer 41, so as to protect the cable 5.

[0026] like Figure 2 As shown, the seal 4 is arranged on the protective bracket 4 through the mounting opening 44; at the same time, the material of the seal can be selected from epoxy resin. The seal 4 has the following two functions:

[0027] First, the seal 4 can prevent moisture or water vapor from entering the protective compartment 7 through the installation opening 44 when the outer layer of the composite cable body 8 is damaged, thereby causing a short circuit in the cable 5 .

[0028] Secondly, the seal 4 can improve the overall wear resistance of the composite cable body 8 to a certain extent, and prevent the protective bracket 4 from directly contacting the outside due to the poor wear resistance of the insulating layer 2 when the outer sheath 1 is damaged.

[0029] like Figure 2 As shown, the metal reinforcement 6 is disposed inside the round tube 43, and the diameter of the metal reinforcement 6 matches the inner diameter of the round tube 43. The material of the metal reinforcement 6 can be brass to increase the overall bending resistance and strength of the composite cable body 8.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
