Power adapter for interconnecting different types of power connectors

A power adapter, comprising:

• a first power connector comprising a first housing having a first abutment surface at a rear end thereof and a first contact module having a plurality of first contact unit, the first housing defining a plurality of passageways at a front end, and a rear slot defined from the first abutment surface and communicating with the passageways, each first contact unit having a body potion remained in the rear slot and a plurality tail portions extending forwardly from an edge of the body portion and received in a corresponding passageway;
• a second power connector comprising a second housing and a plurality of second contacts, the second housing having a second base having a second abutment surface and a forwardly projecting shroud defining a receiving cavity therein, the second base defining a plurality of second passageways extending from the second abutment surface through the second base and communicating with the receiving cavity, each second contact comprising a contact portion projecting into the receiving cavity and a mounting portion retained in a corresponding second passageway and extending outwardly beyond the second abutment surface;
• wherein
• the first connector and the second connector are fastened with each other in a back-to-back manner, the first abutment surface of the first housing confronts the second abutment surface of the second housing, and the mounting portions of the second contacts mate with corresponding body portions of the first contact modules.

A power adaptor comprising:

• different first and second connectors substantially back to back assembled to each other,
• said first connector including a first housing with a plurality of first contacts therein and a first mating port thereof for coupling with a complementary first connector,
• said second connector including a second housing with a plurality of second contacts therein and a second mating port thereof for coupling with a complementary second connector different from said first complementary connector,
• some of said first contacts being grouped with plural sets in compliant contact with a number of the second contacts along a front-to-back direction;
• wherein
• a pitch of said plural sets of first contacts is different from that of said plural second contacts;
• wherein
• each of said plural sets engages the corresponding second contact at one specific relative position thereof, which is different from another specific relative position of another of said plural sets where another corresponding second contact engages, so as to allow the sets of first contacts and the second contacts, with pitches different from each other, to be interconnected with each other without varying configurations of said sets of first contacts and said second contacts individually for compensating pitch difference.
