Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a high-speed line backplane connector plug. Background Art

[0002] The backplane connector is generally composed of two pairs of connectors, which are connected to each subsystem through the conversion of the PCB circuit board. The specific method is to install the backplane connector plug on the edge of the subsystem board and install the socket on the PCB circuit board. The socket and plug on the PCB circuit board are connected through the signal line. The two system boards are plugged into each other through the backplane connector plug and the socket on the PCB circuit board, thereby connecting the two subsystems.

[0003] As we all know, PCB circuit boards are generally made of glass fiber mesh cloth and the signal lines arranged on it, which are bonded together by resin. As the signal transmission rate increases, the glass fiber mesh cloth of PCB circuit boards has become the biggest shortcoming in signal transmission. The reason is that the glass fiber mesh cloth is arranged in an up-down structure, and there is always a gap between the signal line and the glass fiber mesh cloth, which is filled with resin. The signal line is equivalent to switching back and forth between the glass fiber mesh cloth and the resin. Because the electrical properties of the glass fiber mesh cloth and the resin are different, the signal will be lost when passing through these two media, just like the light passing through the interface between air and water, part of the light will scatter in other directions to weaken the light intensity, which leads to the transmission loss problem of the signal line on the PCB circuit board.
