Description

Plug cable assembly Technical Field The utility model relates to the technical field of plug cables, in particular to a plug cable assembly. Background The main working content of the plug cable assembly is that different devices are connected through cables to realize electric connection and signal transmission, when a plug is inserted into a socket, a metal contact sheet and a metal contact in the socket form a closed circuit, and current can pass through to drive electric equipment to operate. When the assembly works, the insulation distance between conductors cannot be effectively ensured, and once the insulation paint layer on the surface of the conductor is damaged, aged and the like, short-circuit faults are extremely easy to occur, and electromagnetic leakage and invasion of external electromagnetic interference in the signal transmission process are caused. Electromagnetic leakage can enable signal energy to be dispersed, strength and definition of signals are reduced, and after the device works for a long time, the connection part is easy to break due to excessive bending, so that electric transmission is unstable.
