Abstract:
1. A receptacle connector matched with a plug connector, comprising: an insulating housing having a base portion and a tongue portion protruding forward from a front of the base portion, a rear of the base portion being concaved inward to define an accommodating space, the insulating housing defining a plurality of upper terminal grooves penetrating through a top of the tongue portion and an upper portion of the base portion to communicate with the accommodating space, and a plurality of lower terminal grooves penetrating through a bottom of the tongue portion and a lower portion of the base portion to communicate with the accommodating space; a plurality of upper terminals of which each has a first fastening portion disposed in the upper terminal groove, a front of the first fastening portion connecting with a first contact portion projecting beyond the top of the tongue portion from a front of the upper terminal groove to electrically contact with the plug connector, and a rear of the first fastening portion connecting with a first soldering portion projecting into the accommodating space from a rear of the upper terminal groove; a plurality of lower terminals of which each has a second fastening portion disposed in the lower terminal groove, a front of the second fastening portion connecting with a second contact portion projecting under the bottom of the tongue portion from a front of the lower terminal groove to electrically contact with the plug connector, and a rear of the second fastening portion connecting with a second soldering portion projecting into the accommodating space from a rear of the lower terminal groove; a locating element positioned in the accommodating space, the locating element defining a plurality of through-holes aligned with the upper and lower terminal grooves respectively for positioning the corresponding first and second soldering portions therein, the first soldering portions and the second soldering portions further passing through the through-holes to project behind the locating element for being soldered with a circuit board; and a shielding shell surrounding the insulating housing, wherein the shielding shell includes a first shielding shell having a bottom plate, two first side plates and a first top plate which are interconnected to define an accommodating chamber thereamong, the insulating housing together with the upper terminals, the lower terminals and the locating element is inserted into the accommodating chamber, wherein a bottom face of the base portion defines two first recesses at a front side thereof, and two second recesses at a rear side thereof and in alignment with the two first recesses respectively, the first recess is spaced from the second recess to define a blocking portion therebetween with a guiding surface being formed in a front thereof, two portions of a top face of the base portion protrude upward to form two buckling blocks, two portions of a rear end of the bottom plate are punched inward to form two resisting pieces sliding into the second recesses through the first recesses and along the guiding surfaces, the resisting pieces are blocked in the second recesses by the blocking portions, the first top plate defines two notches at a rear thereof for buckling the two buckling blocks.
