Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a combined cable. Background Art

[0002] As an indispensable component of electrical and electronic systems, cables carry the heavy responsibility of transmitting current and signals. From simple power cables to complex data communication cables, cables are of various types and widely used. With the advancement of science and technology, cable technology is also constantly developing. Modern cables are not only required to have good electrical conductivity and signal transmission stability, but also need to meet special requirements such as environmental protection, flame retardancy, and high temperature resistance. At the same time, the manufacturing process of cables is also constantly improving, such as the use of high-precision automated equipment for production, and the application of advanced testing technology to ensure cable quality. In terms of materials, the application of new alloys, polymer materials, etc. has also brought better performance and a wider range of application space for cables.

[0003] As the name implies, a combined cable is a special cable composed of multiple cables. The original intention of designing this cable is to meet the needs of simultaneous transmission of multiple currents and signals in complex systems. The combined cable can contain multiple types of cables such as power cables, signal cables, and control cables. They each undertake different transmission tasks, but are protected and fixed by a unified external sheath. This design not only improves the integration of cables, reduces wiring space, but also facilitates the installation and maintenance of the system. With the continuous advancement of technology, the manufacturing process and materials of combined cables are also constantly innovating. For example, the use of advanced twisting technology and shielding technology can improve the anti-interference ability of cables, and the application of new environmentally friendly materials makes combined cables more in line with the requirements of sustainable development.

[0004] The combination cable in the prior art usually has a layer of insulation sheath on the outside of multiple branch cables to form a complete cable. However, when one or several cables inside need to be repaired or replaced, the outer insulation sheath must be destroyed, and then the cables that need to be repaired must be pulled out for repair or replacement. Afterwards, the repaired cables must be put back into the insulation sheath, and the damaged insulation sheath must be repaired. This method is not only complicated and cumbersome, but it is also easy to accidentally damage the internal cables in the process of damaging the insulation sheath. Another method is to pull out the internal branch cables from one end of the cable, but due to the large friction between the cable materials, it is often difficult to put the repaired branch cables back into the cable. Therefore, there is an urgent need for a combination cable that is convenient for separating the internal cables from the outer insulation sheath and for refilling. Utility Model Content
