Electrical connector having contacts with anti-wicking means

摘要

An electrical connector (1) for soldering to a printed circuit board includes a housing (10) defining a number of channels (22) therethrough, a number of contacts (12) received in corresponding channels. At least two contacts share a same channel. Each contact includes an intermediate portion (124) pre-coated with a Sn-Pb plating which has a higher melting point than that of the soldering paste. The intermediate portions of corresponding contacts in the same channel are soldered with each other by heating the Sn-Pb plating and a wicking barrier (28) is formed on soldering area. The wicking barriers block the melted soldering paste from passing therethrough to thereby protect contact portions when soldering the contacts with the printed circuit board.
