Electrical connector with power contacts designed to handle instantaneous inrush current

An electrical connector assembly, comprising:

• a first connector having an insulative body, and a plurality of terminals assembled onto the insulative body;
• a second connector for mating with the first connector, the second connector, comprising:
• an insulative housing including a mating tongue;
• and
• a plurality of contacts assembled onto the insulative housing, comprising:
• two power contacts being on two opposite side regions of the mating tongue;
• two power ground contacts associated with said two power contacts;
• wherein
• the first connector and the second connector mate at a position where one of said two power contacts is electrically engaged by a corresponding terminal of the first connector while the other of said two power contacts is not electrically engaged;
• wherein the second connector comprising three type contacts including three signal ground contacts located between said two power contacts and two pairs of signal contacts, each pair being located between the corresponding two adjacent signal ground contacts, said signal contacts, said signal ground contacts and said power contacts are disposed on a same face of the mating tongue;
• wherein said two power ground contacts located at a plane different from that of said power contacts, said signal contacts and said signal ground contacts.

An electrical connector comprising:

• a mating port defining a mating face;
• a mating tongue exposed in said mating portion;
• four type contacts including:
• two first type contacts located on two opposite side regions of the mating portion;
• second and third type contacts disposed on a same face of the mating tongue and located between said two first contacts;
• two fourth type contacts located on said two opposite side regions while being located at a different level with regard to the first type contacts;
• wherein said first type contacts are named as power contacts, the second type contacts as signal contacts, the third type contacts as signal ground contacts for the signal contacts to ground, and the fourth type contacts as power ground contacts for the power contacts to ground;
• wherein said two power contacts are located on the mating tongue and wider than said signal contacts and said signal ground contacts, under a condition that the signal ground contacts extend forwardly beyond the signal contacts and one of said power contacts extends forwardly longer than the other of said power contacts to be flush with the signal ground contacts while the other of said power contacts extending forwardly to be flush with the signal contacts.
