Plug connector assembly and manufacturing method of the same

A method of manufacturing a plug connector assembly, comprising the steps of:

• processing first core wires to expose respective inner conductors and shielding layers thereof;
• fixing the first core wire to a wire management block and positioning the exposed shielding layer and the inner conductor on a front side of the wire management block;
• processing a second core wire to expose an inner conductor thereof;
• engaging the second core wire into a fixing hole of the wire management block and arranging the inner conductor of the second core wire beside the shielding layers of the first core wires;
• soldering the inner conductors of the first core wires to corresponding first conductive pads of a printed circuit board at a first stage;
• and
• soldering the inner conductor of the second core wire and the shield layers to corresponding second conductive pads of the printed circuit board at a second stage after the first stage;
• wherein
• the fixing hole is essentially an open type clamping slot to communicate with an exterior in a vertical direction so that the second core wire is retained in the fixing hole only after the first stage and before the second stage for not only not hindering soldering the inner conductor of the first core wires to the first conductive pads during the first stage but also stably holding the second core wire in position during the second stage.

A plug connector assembly comprising:

• a housing;
• a printed circuit board received in the housing, the printed circuit board including first conductive pads laterally arranged in a row in a transverse direction, and one or more second conductive pads arranged in another row in the transverse direction, and located behind the first conductive pads in a front-to-back direction perpendicular to the transverse direction;
• a wire management block;
• and
• a cable electrically connected with the printed circuit board, the cable including a plurality of first core wires and a plurality of second core wires, each of said first core wires including a first inner conductor and a shielding layer surrounding the first inner conductor, each of the second core wires including a second inner conductor, each of the first core wires being mounted to the wire management block while exposing the first inner conductor and the shielding layer at a front side of the wire management block, wherein
• the wire management block is provided with a plurality of clamping slots, the clamping slots run through the wire management block along the front-to-back direction, each of the second core wires is clamped in the corresponding clamping slot and exposes the second inner conductor at the front side of the wire management block, the first inner conductors of the first core wires are arranged in a row and soldered to the first conductive pads of the printed circuit board via a first soldering strip, and the second inner conductors of the second core wires and the shielding layers of the first core wires are arranged in another row and soldered to the one or more second conductive pads of the printed circuit board via a second soldering strip.
