Abstract
The utility model relates to a high-frequency wire shielding wrapping band structure. The high-frequency wire shielding wrapping band structure is wrapped around a core wire. The high-frequency wire shielding wrapping band structure is a spiral structure which is formed in a manner that shielding foils are spirally wrapped around the core wire. The spiral structure is composed of multiple circles of spiral single bodies. A metal foil is adhesive to a Mylar to form each shielding foil. Each shielding foil comprises a body part and a folding part. A first overlapping conductive surface is formed on each body part, and a second overlapping conductive surface is formed on each folding part. The first overlapping conductive surface on the body part of any circle of the spiral single bodies is connected with the second overlapping conductive surface on the folding part of another spiral single body in an overlapping manner to form an overlapping part. In the overlapping part, the metal foil on the first overlapping conductive surface is contacted with the metal foil on the second overlapping conductive surface. According to the high-frequency wire shielding wrapping band structure, the body part and the folding part are disposed on each shielding foil, contacting connections are formed at the overlapping parts between the spiral single bodies, signals can be directly transmitted from each front spiral single body to each rear spiral single body when the signals are transmitted in the shielding foils, and an effect which occurs because each shielding foil discontinuously faces high-frequency signals is reduced.
