Title:
DUAL-SHIELDING LAYER USB CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2018/171241
Kind Code:
A1
Abstract:
Provided is a USB suspension design method with low electromagnetic interference. Especially in a scenario where the distance between a pin and a metal housing of a USB interface of a terminal device becomes smaller and smaller, a connection line having a first shielding layer and a second shielding layer is used to connect a first plug and a second plug, wherein the first shielding layer and the second shielding layer overlap and are not in electrical connection with each other; one end of the first shielding layer is connected to a metal housing of the first plug, and the other end thereof is suspended; and one end of the second shielding layer is connected to a metal housing of the second plug, and the other end thereof is suspended. In addition, the metal housing of the first plug and the metal housing of the second plug can be connected to the housing of the terminal device or a housing of an adapter by means of an over-capacitive element. The present invention facilitates the reduction of the risk of short circuiting and the radiation of a terminal device.
