Abstract
Abstract An electrical connector ( 10 ) includes an insulative housing ( 20 ) having a mating face ( 21 ) and a mounting face ( 22 ) and a plurality of contacts ( 30, 40 ). Two receiving slots ( 26 ) are defined between the mating face and the mounting face. A plurality of passageways ( 24 ) are defined in the housing and communicate with the receiving slots. The contacts are arranged into the passageways. Each contact comprises a contact portion ( 301, 401 ) received in the passageway and partly exposed in the slot, a first mounting portion ( 303, 403 ) fixed within the housing, a second mounting portion ( 306, 406 ) offset the first mounting portion and fixed with the housing, a bending portion ( 304, 404 ) having a first part bent toward the contact portion and a second part connecting with the second mounting portion, and tail portion ( 306, 406 ) extending downwardly from the second mounting portion.
