Ultra high speed signal cable connector and assembly method thereof

Abstract

An ultra high speed signal cable connector includes an insulating housing, a PCB fixedly mounted inside the insulating housing, and at least one row of cables without grounding wires welded to the PCB. The end portion of a connecting finger of the PCB extends out of the insulating housing, and the PCB is provided with a signal bonding pad and a grounding wire bonding pad. Each cable without grounding wires includes a plurality of electric wires, a conductive jacket for wrapping the plurality of electric wires together, and an insulating jacket wrapped on the outer layer of the conductive jacket. Each electric wire includes a core wire and an insulating layer wrapped on the outer layer of the core wire. One ends of the core wires are welded on the signal bonding pad; a section of insulating jacket is stripped from the foremost end of each cable without grounding wires to expose the conductive jacket. The conductive jackets are electrically and fixedly connected to the grounding wire bonding pad. According to the ultra high speed signal cable connector provided by the present disclosure, there is no need to weld the grounding wire during welding, the welding efficiency can be significantly improved, the connector is compact in structure, small in occupied space and high in strength, and the inner mold is adopted to wrap the welding spots between the cables and the PCB, so that the welding spots are protected, and the electrical performance is significantly improved compared with that of the existing products.
