Electrical connector with connecting bars therein to reduce cross talking

An electrical connector assembly for mounting to a printed circuit board, comprising:

• an elongated insulative housing defining a lengthwise direction and a transverse direction perpendicular to the lengthwise direction;
• a mating port formed in the housing along said lengthwise direction and forwardly communicating with an exterior in a front-to-back direction perpendicular to said lengthwise direction and said transverse direction;
• and
• a set of contacts including at least two differential pair contacts for signal transmission and three grounding contacts alternately arranged with each other along the lengthwise direction;
• wherein
• a connecting bar extends along the lengthwise direction and is linked at and unitarily formed with front ends of said three grounding contacts;
• wherein
• the housing defines a mating tongue in the mating port, and the contacting define corresponding contacting sections exposed upon the mating port under condition that said connecting bar is essentially hidden in a front edge of the mating tongue;
• wherein
• the contacts are integrally formed with the housing via insert molding;
• wherein the housing includes a first part and a second part discrete from each other while being assembled together in the transverse direction under condition that the contacts are integrally formed with the first part via insert molding.

An electrical connector assembly comprising:

• an insulative housing defining a lengthwise direction and a transverse direction perpendicular to each other;
• said housing defining a mating tongue extending along the lengthwise direction and defining opposite first and second surfaces in said transverse direction;
• a first group of contacts disposed in the housing with first contacting sections exposed on the mating tongue, said first group of contacts including first differential pair contacts and first grounding contacts;
• and
• a second group of contacts disposed in the housing with second contacting sections exposed on the mating tongue, said second group of contacts including second differential pair contacts and second grounding contacts;
• wherein
• the two outermost ones of said first group of contacts are the first grounding contacts to enclose the first differential pair contacts therebetween in the lengthwise direction under condition that a first connection bar connects to said two outermost ones of the first group of contacts;
• the two outermost ones of said second group of contacts are the second grounding contacts to enclose the second differential pair contacts therebetween in the lengthwise direction under condition that a second connection bar extends in the lengthwise direction and connects to said two outermost ones of the second group of contacts;
• wherein
• said first group of contacts and said second group of contacts are directly neighboring to each other without any other contacts therebetween in said lengthwise direction;
• wherein
• both the first group of contacts and the second group of contacts include corresponding contacting sections exposed upon a same face of said mating tongue, and a pair of ribs are formed on an opposite face of the mating tongue, said pair of ribs being spaced from each other in the lengthwise direction while each of said pair of ribs extending in a front-to-back direction perpendicular to both said lengthwise direction and said transverse direction.
