Cable electrical connector assembly having an insulative body with a slot

A cable assembly comprising:

• a printed circuit board having a surface defining thereon region and a rear region along a front-to-back direction;
• a plurality of front pads formed on the front region;
• a plurality of rear pads formed on the rear region and electrically connected to the corresponding front pads
• a plurality of wires including inner conductors with exposed front end sections mechanically and electrically connected to the corresponding rear pads, respectively;
• and
• an insulative body applied upon the surface to enclose the rear pads and the exposed front end section of the corresponding wires;
• wherein
• a slot is formed in the insulative body between a pair of rear pads in a transverse direction perpendicular to said front-to-back direction to increase impedance thereabouts.

A method of assembling an cable assembly comprising steps of:

• providing a printed circuit board with a plurality of front pads and a plurality of rear pads along a front-to-back direction on a surface thereof;
• providing a plurality of circuit traces on the surface to electrically connect the corresponding front pads and rear pads;
• providing a plurality of wires with exposed inner conductors;
• soldering said exposed inner conductor to the corresponding rear pads, respectively;
• applying an insulative body upon the surface to cover the rear pads and the exposed inner conductors of the corresponding wires in a vertical direction perpendicular to said front-to-back direction;
• and
• forming a slot in said insulative between a pair of rear pads, which belong to a differential pair, in a transverse direction perpendicular to both said front-to-back direction and said transverse direction.
