Patent ID: 7473143

Claim:
A low profile electrical connector comprising: a plurality of conductors ( 2 ); an insulative housing ( 1 ) including a seat ( 11 ), a mating portion ( 15 ) extending forwardly from the seat ( 11 ) and having a plurality of parallel troughs ( 181 ), a first groove ( 12 ) on a middle of an upper surface of the seat ( 11 ), each of two spaced second grooves ( 13 ) on a side portion of a front end of a lower surface of the seat ( 11 ), two spaced cavities ( 14 ) each on a side portion of a rear end of the lower surface of the seat ( 11 ) and the open side direction thereof opposite to that of the second grooves ( 13 ), two arms ( 16 ) each extending rearward from two rear corners of the seat ( 11 ) and each having a pole ( 161 ) projecting downward from an end of the arms ( 16 ), and a well ( 17 ) on a rear end of the seat ( 11 ) and having a plurality of through holes ( 18 ) communicating with the corresponding troughs ( 181 ) for disposing the conductors ( 2 ) therein; and a rectangular metal shell ( 3 ) including a first surface ( 31 ) having a first latching portion ( 311 ) disposed at a middle of the first surface ( 31 ) corresponding to the position of the first groove ( 12 ), a second surface ( 32 ) having two second latching portions ( 321 ) each disposed at a side portion of the second surface ( 32 ) corresponding to the position of the second grooves ( 13 ) and cavities ( 14 ), two sides ( 33 ) each interconnecting the first and second surfaces ( 31 , 32 ), and two spaced flexible latches ( 34 ) extending outward from either side ( 33 ), the latch ( 34 ) including a level portion ( 341 ) having a top concave portion ( 343 ), and a solder leg ( 342 ) extending downward from the level portion ( 341 ) and having a curved portion ( 344 ) extending from the concave portion ( 343 ) to the solder leg ( 342 ); wherein upon assembling, the first latching portion ( 311 ) is lockingly engaged with the first groove ( 12 ) and the second latching portions ( 321 ) are lockingly engaged with the second grooves ( 13 ) and the cavities ( 14 ) for securing the insulative housing ( 1 ) to the metal shell ( 3 ); and the insulative housing ( 1 ) and the metal shell ( 3 ) together are mounted at a recess ( 40 ) on an edge of a printed circuit board (PCB) ( 4 ) by inserting the solder legs ( 342 ) into a plurality of first holes ( 41 ) of the PCB ( 4 ) and inserting the poles ( 161 ) into a plurality of second holes ( 42 ) of the PCB ( 4 ) respectively with a bottom of the level portions ( 341 ) firmly rested upon the PCB ( 4 ) to thereby lower a profile of the whole connector above the PCB.
