Abstract: A signal transmission line disposed with a conductive plastic material layer is provided, which relates to the field of signal transmission line technologies, and specifically to electromagnetic interference (EMI) protection of the signal transmission line. The signal transmission line at least includes a metal wire disposed with an insulation layer, a conductive plastic material layer is disposed outside the metal wire disposed with the insulation layer, and an insulation outer coating layer is disposed outside the conductive plastic material layer. A conductive plastic material layer is used as a shielding layer for EMI protection. The conductive plastic material is also called conductive polymer plastic and has characteristics such as good conductivity and good antistatic property.

Abstract: An integral data line storage structure of a digital device relates to the technical field of digital devices, and in particular, to improvements of a data connection line storage structure of a digital device such as a mobile hard disk, a multimedia player, a DV, a digital camera, a mobile phone, a tablet computer, an MP4, or a recorder pen, so as to solve the technical disadvantage that the data connection line matching the existing digital device is inconvenient to carry and store. The integral data line storage structure of a digital device includes a digital device body and a data connection line connected to the digital device body. The data connection line is of a flat shape through injection molding, and a wiring groove for receiving the data connection line when not used is disposed on the digital device body.
