US Patent 7607947 Electrical connector

An electrical connector adapted for being electrically connected with a PCB stably, includes an insulating housing defining a plurality of terminal passageways for receiving terminals and at least one through-hole located at one side of the terminal passageways. The insulating housing has two opposite holding blocks which defines two guiding recesses facing each other for locating the PCB. A shell encircles the insulating housing and defines at least one pressing slice passing through the through-hole and pressing against one surface of the PCB. Each of the terminals has a soldering portion exposed out of the terminal passageway and pressing against the other surface of the PCB.
