The output member 10 is provided as required, and the output member 10 may be a flip-chip signal terminal connected to another crystal head, or may be a clip-type terminal or a piercing-type signal terminal connected to a subsequent network cable. When an external plug is inserted into the plug cavity 44 and is communicatively connected to the input terminal 11, the electrical signal from the external plug will pass through the input terminal 11 and then enter the transmission line layer inside the PCB 2, pass through the transmission line layer to the output component 10, and pass through the output component 10 to the subsequent network cable, control chip, crystal head, etc. Because this embodiment replaces the insulation board in traditional connector through adopting PCB board 2, avoids in traditional setting mode because the separation of plastic slab, and the problem that leads to the unable improvement of signal transmission rate.
