However, with the development of electronic technology, especially the widespread use of digital circuits, mobile communications and switching power supplies, there is also an increase in intangible pollution that is not perceived by the senses, namely electromagnetic interference (EMI), or electromagnetic noise. With the improvement of the intelligent degree of the automobile, the electromagnetic energy formed by the automobile electronic equipment in the automobile driving environment is more and more complex and variable, which also means that the system is subjected to a wider source of electromagnetic interference.
The automobile wire harness is spread over the whole automobile, is a main source of electromagnetic interference in the automobile, and is often interfered by the electromagnetic interference, so how to deal with the electromagnetic interference by the automobile wire harness is particularly important. For low-voltage wires, the following design is mainly selected to deal with electromagnetic interference: twisted pair wires are used, shielded wires are used, and a shielding protector is used for the wires, and shielding tape is one of the shielding protectors.
The conventional shielding tape is easily damaged due to the structure of the shielding tape. Usually can twine the PVC sticky tape of no glue again at shielding sticky tape skin in practical application, such combination has solved the too thin easy damaged problem of shielding sticky tape, but has brought very big problem for the production staff in the technology, great increase staff's man-hour to because the characteristic of PVC substrate itself, such combination is not fit for using under the environment that has high temperature resistant, high resistant and high wear-resisting demand.
In conclusion, the existing shielding adhesive tape has the defects of easy damage, inconvenient use, poor applicability and the like.
