Description

Technical Field

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

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply for industrial and mining enterprises, and underwater power transmission lines across rivers and seas.

[0003] For example, a cable with authorization announcement number "CN 2724154Y" can be fixed to soft materials, ultra-hard steel, and fragile surfaces, making wiring construction simpler, with a wide range of applications, convenient on-site construction, reduced labor intensity, improved work efficiency, and good fixing effect. However, this device is not convenient for supporting the internal core of the cable. When the cable is transported or subjected to compression, the device cannot effectively support the internal structure, making it prone to damage. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of easy damage to the device, and a cable is proposed accordingly.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a cable including an insulating outer layer and a metal braided layer, wherein the metal braided layer is fixedly connected to the inner wall of the insulating outer layer, and an insulating layer is fixedly connected to the inner wall of the metal braided layer, wherein the insulating layer abuts against multiple wire cores through grooves opened in its inner wall.

[0007] Preferably, the outer walls of the plurality of wire cores are all abutted against the bracket, and the inner wall of the bracket is fixedly connected to the steel wire.

[0008] Preferably, the outer wall of the bracket has multiple arc-shaped grooves.

[0009] The cable proposed in this utility model has the following advantages: through the cooperation of the bracket and the metal braided layer, the strength of the device can be effectively improved under the action of the bracket and the metal braided layer, so that the squeezing during handling and use can be blocked, and the pressure that can be withstood can be greater. At the same time, the insulating layer can prevent the core wires from being damaged when sharp objects pierce the outer side of the insulation due to excessive pressure, thus making the device more durable and less prone to damage during transportation and use. Under the action of the bracket, the stability between multiple core wires can be supported, and the device can be further supported, increasing its strength and making it more durable and less prone to damage.

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] See attached document Figure 1-4 In this embodiment, a cable includes an outer insulating layer 1 and a metal braided layer 6. The outer insulating layer 1 is made of rubber. The inner wall of the outer insulating layer 1 is fixedly connected to the metal braided layer 6. The inner wall of the metal braided layer 6 is fixedly connected to an insulating layer 5. The insulating layer 5 is pressed against multiple wire cores 4 through grooves opened in its inner wall. The outer walls of the multiple wire cores 4 are pressed against a bracket 2. The inner wall of the bracket 2 is fixedly connected to a steel wire 3. The outer wall of the bracket 2 has multiple arc-shaped grooves. The bracket 2 is made of rubber, the metal braided layer 6 is made of stainless steel wire, and the insulating layer 5 is made of rubber. The insulating layer 5 can isolate the metal braided layer 6 and the wire cores 4, preventing contact between the metal braided layer 6 and the wire cores 4. The metal braided layer 6 can increase the common tensile strength from 500MPa to 1500MPa.

[0017] Working principle:

[0018] When transporting and using cables:

[0019] The support 2 and the metal braided layer 6 effectively improve the strength of the device, preventing compression during handling and use and allowing it to withstand greater pressure. At the same time, the isolation layer 5 prevents the core wire 4 from being damaged when sharp objects puncture the outer insulation layer 1 due to excessive pressure, which would damage the metal braided layer 6. The steel wire 3 can improve the tensile strength during tension, making the device more durable and less prone to damage during transportation and use. The support 2 can also support the stability between multiple core wires 4.

[0020] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
