Housing to prevent wicking of molten solder and flux |
摘要 |
An electrical connector of the present invention comprises an insulative housing defining a plurality of contact receiving holes for receiving corresponding contacts. The housing forms a protrusion laterally extending into each contact receiving hole from a bottom of an inner wall thereof. Each contact includes an upper contacting section for engaging with a mating lead pin of a chip, a middle fixing section located below the upper contacting section for having an interferential fit with the housing, and a lower inserting section for being soldered to a printed circuit board. The fixing section has an embossment for engaging with the protrusion of the housing to sealingly separate the lower inserting section from the upper contacting section so that solder and flux is prevented from wicking upward to contaminate the upper contacting section when soldering the lower inserting section to the printed circuit board.
