资料介绍

The signals between the top and bottom of the receptacle tongue are isolated by a mid-plate inside the tongue. Figure 3-10 shows a reference design of the mid-plate. It is important to pay attention to the following features of the middle plate:

· The distance between the signal contacts and the mid-plate should be accurately controlled since the variation of this distance may significantly impact impedance of the connector.

· The mid-plate in this particular design protrudes slightly beyond the front surface of the tongue. This is to protect the tongue front surface from damage caused by miss-

insertion of small objects into the receptacle.

· The mid-plate is required to be directly connected to the PCB ground with at least two grounding points.

· The sides of the mid-plate mate with the plug side latches, making ground connections to reduce EMC. Proper surface finishes are necessary in the areas where the side latches and mid-plate connections occur.
