Electrical connector with improved contacts retaining mechanism

Abstract

An electrical connector includes an insulative housing having a front mating face, a base portion, a mating portion protruding forwardly from the base portion and a number of passageways recessed rearward from the front mating face, the housing defining a number of blocks on a rear side thereof, the blocks each having an abutting face on a lower end thereof; a number of first contacts received in the passageways respectively and each including a contacting portion exposed in the passageway to mate with a corresponding mating connector, a level retaining arm fixed in the passageway and defining a front end connecting with the contacting portion and a rear end opposite to the front end, and a vertical mounting portion extending downwardly from a rear end of the retaining arm, the vertical mounting portion including a soldering portion to be soldered onto a printed circuit board and a protrusion tab extending laterally to have a larger width than that of the soldering portion, the protrusion tab abutting against the abutting face to prevent the vertical mounting portion from moving upwardly.
