Plug connector with improved cable arrangement

A plug connector comprising:

• a unitary longitudinal insulative housing defining an uninterrupted central receiving cavity along a lengthwise direction, the central receiving cavity defining a middle portion in said lengthwise direction, said housing comprising opposite first and second sidewalls located at two elongated sides of said central receiving cavity, said second sidewall being thicker than the first sidewall in a transverse direction perpendicular to said lengthwise direction;
• a recess recessed from an inner face of the second sidewall and in communication with the middle portion of the central receiving cavity along said transverse direction;
• and
• an expansion portion integrally formed on an exterior face of the first sidewall and in alignment with the cavity in said transverse direction;
• a plurality of contacts received in the second sidewall;
• and
• a plurality of wires respectively electrically connecting with the contacts;
• and wherein
• at least a pair of wires are arranged to extend along opposite directions perpendicular to said lengthwise direction and electrically connect with the same contact.

A plug connector comprising:

• an insulative housing defining a mating port along a longitudinal direction and communicatively exposed to an exterior in a front-to-back direction perpendicular to said longitudinal direction;
• a plurality of contacts disposed in the housing, each of said contacts defining a contacting section extending into the mating port and a tail section mechanically and electrically connected to a printed circuit board which extends in a plane perpendicular to said front-to-back direction;
• a first group of wires mechanically and electrically connected to the printed circuit board in a first transverse direction perpendicular to both said longitudinal direction and said front-to-back direction;
• a second group of wires mechanically and electrically connected to the printed circuit board in a second transverse direction perpendicular to both said longitudinal direction and said front-to-back direction while opposite to said first transverse direction.
