Electrical connector having low board mounting profile

Claim 1

An electrical connector, comprising: an insulated housing having an elongated base portion with a mating head and a bottom-end opposite to the mating head; a mounting foot formed on the bottom-end, said mounting foot engaging a top mounting surface for mounting said electrical connector to a circuit board; a metal fitting member set on the top mounting surface of the mounting foot; and a plurality of terminals inserted into said insulated housing from the bottom-end to the mating head; a protrusion is formed on the top mounting face to leave an intervening space around the metal fitting member to avoid floating of the connector while it is welding; a pair of guiding blocks parallel to the base portion and join with elongated two ends of the base portion, the top end of each guiding block is located above the mating head; a mating slot is hollowed on the base portion vertical to the top mounting surface, and said mating slot is L-shaped; the mounting foot defines a slit, and wherein the metal fitting member has an engaging section retained in the slit and a fitting section for engaging the circuit board; said metal fitting member is assembled to the mounting foot through the back surface and extending from the top mounting surface; said mounting foot defines a back surface opposite and parallel to the top mounting surface, some supporting portions are extending from the back surface at a boundary of the mounting foot; two molding posts extending from the mounting surface in different size for keying and positioning the connector.
