Electrical connector and electrical connector assembly with the same

An electrical connector, comprising:

• an insulative housing having a plurality of contact-receiving passageways extending along a front-and-back direction;
• and
• a plurality of power contact pairs mounted in the corresponding contact-receiving passageways, and each power contact pair having two power contacts, each power contact defining a flaky retaining portion held in the relative contact-receiving passageway, a number of contacting portions extending forwards from a front end of the retaining portion and a soldering portion extending from a rear end of the retaining portion;
• wherein
• the contacting portions of the two power contacts in each power contact pair are arranged alternately and circularly, and one of two neighboring contacting portions has a projection on a vertical plane at least partially overlapped with that of the other of two neighboring contacting portions.

An electrical connector assembly, comprising:

• an insulative housing having two rows of contact-receiving passageways separating from each other via a transverse interval wall, and each contact-receiving passageway extending along a front-and-back direction;
• a plurality of power contact pairs mounted in the corresponding contact-receiving passageways, and each power contact pair having two power contacts, each power contact defining a flaky retaining portion held in the relative contact-receiving passageway, a number of contacting portions extending forwards from the retaining portion and a soldering portion extending from a rear end of the retaining portion;
• and
• a printed circuit board connected with the soldering portions of the power contact pairs;
• wherein
• the contacting portions of the two power contacts in each power contact pair are arranged alternately and circularly, and located on one side of the interval wall of the insulative housing in a height direction.
