Abstract:
1. An electrical connector to be mounted on a printed circuit board, comprising: an insulative housing having a front mating face, an upper wall, a lower wall, a receiving cavity recessed rearwardly from the front mating face to receive a mating plug and a plurality of passageways; and a plurality of contacts retained in the passageways respectively, including: a first contact having a first vertical base portion extending along a height direction of the housing, a first contacting arm projecting inwardly into the receiving cavity, a connection portion connecting with the first vertical base portion and the first contacting arm, and a first soldering portion connected to a bottom end of the first vertical base portion; wherein the connection portion is disposed between the first vertical base portion and the first contacting arm along a lateral direction of the housing, the connection portion includes a first curved portion being curved forwardly from an upper side of the first vertical base portion, a second curved portion connected to the first contacting arm and a vertical plate portion connecting with both the first curved portion and the second curved portion, both the connection portion and the first contacting arm is deflectable; wherein the lower wall defining a retaining hole extending therethrough, the retaining tab is fixed in the retaining hole and extends beyond the lower wall to be mounted onto the printed circuit board; wherein the first vertical base portion defines a lower side edge, and an upper side edge connecting with the first curved portion, the upper side edge extends upwardly and obliquely with respect to the lower side edge; wherein the first vertical base portion is of trapezium shape, the first contacting arm extends rearwardly from the second curved portion, the second curved portion defines a pair of opposite vertical side edges connected to the first contacting arm and the vertical plate portion respectively; and wherein the first vertical plate portion defines a protrusion tab extending upwardly from an upper side thereof, the protrusion tab is adjacent to an upper end of the upper side edge, the upper wall defines a first though hole extending therethrough and communicating with the receiving cavity, the protrusion tab is fixed in the first through hole.
