Embodiment Construction
[0028] Such as Figure 1-11 As shown, the plug connector assembly 100 of the present invention includes a plug connector 1 , a cable 2 connected to the plug connector 1 , a sleeve 4 disposed on the cable 2 , and a fixing member 5 disposed on the sleeve 4 . The plug connector 1 includes a conductive outer shell 3 and a circuit board 11 accommodated in the outer shell 3 . The plug connector assembly 100 of this embodiment conforms to the QSFP-DD specification, which defines 8 transmission channels and 8 reception channels, and the signal transmission rate of each channel is above 28Gbps. Of course, the present invention can also be applied to high-speed plug connector assemblies that are being developed such as SFP-DD or other undeveloped high-speed plug connector assemblies with the same or different channel numbers or higher transmission rates.
[0029] The circuit board 11 includes a docking end 110 that can be matched with a docking connector, and a connecting end 111 oppos...

The invention discloses an assembly method of a plug connector assembly. The assembly method comprises the following steps of providing a circuit board, wherein a first row of conductive pieces are arranged on a side surface of the circuit board, and a second row of conductive pieces are arranged at a front side; providing a cable, wherein the cable comprises a plurality of core lines, exposing the core lines out of one end of the cable, processing the core lines to form a first group of core lines and a second group of core lines extending forwards, and welding the first group of core lines and the corresponding first row of conductive pieces; and providing a first insulation piece, wherein the first insulation is arranged at a region where the first group of core lines and the first rowof conductive pieces are welded after the first group of core lines and the corresponding first row of conductive pieces are welded, and the second group of core lines cross over the first insulationpiece and then are welded with the corresponding second row of conductive pieces. The assembly method comprises the step of arranging the first insulation piece. Accident short circuit probably causedby welding of the cable of a high-density plug connector assembly and the circuit board can be prevented.
