双屏蔽层的USB连接器制造技术

本发明专利技术提供一种低电磁干扰的USB悬浮设计方法，特别是在终端设备的USB接口的引脚与金属外壳之间的距离越来越小的场景下，采用具有第一屏蔽层和第二屏蔽层的连接线连接第一插头与第二插头，其中，第一屏蔽层与第二屏蔽层是重叠且无电气连接的，第一屏蔽层的一端连接第一插头的金属外壳，另一端悬空，第二屏蔽层的一端连接到第二插头的金属外壳，另一端悬空。另外，第一插座的金属外壳与第二插座的金属外壳可以用过容性器件连接到终端设备的外壳或者适配器外壳。利于终端设备降低短路的风险以及辐射。

USB Connector with Double Shielding Layer

The invention provides a USB suspension design method with low electromagnetic interference, especially in the case that the distance between the pin of the USB interface of the terminal device and the metal shell is getting smaller and smaller, a connection line with the first shield layer and the second shield layer is used to connect the first plug and the second plug, where the first shield layer and the second shield layer are overlapping and without electrical connection, and the first shield layer is used to connect the first plug and One end is connected to the metal housing of the first plug, the other end is suspended, one end of the second shielding layer is connected to the metal housing of the second plug, and the other end is suspended. In addition, the metal housing of the first socket and the metal housing of the second socket can be connected to the housing of the terminal device or the adapter housing by capacitive devices. It is beneficial for terminal equipment to reduce the risk of short circuit and radiation.
