Novel cable

Technical Field

The invention relates to the technical field of wires and cables, in particular to a novel cable.

Background

A cable is a conductor made of one or more conductors insulated from each other and an outer insulating sheath that carries power or information from one location to another. Typically a rope-like cable made up of several or groups of at least two twisted conductors, each group insulated from each other and often twisted around a center, the entire outer surface being covered with a highly insulating covering. The cable has the characteristics of internal electrification and external insulation.

The cable needs to be butted with two cable wires due to the limited length in the installation process, the traditional butt joint mode usually screws the core conductors of the two cable ends together, winds insulating materials outside and closes the butt joint position, however, the butt joint mode often has some problems:
