A USB3.0 connector includes an insulative body, a plurality of first and second terminals, and an outer shell covering the insulative body. The insulative body includes a base that has a base upper wall, a base lower wall, and two base sidewalls. The base lower wall has a rear end notched in a frontward direction to form a plurality of alternating shallow and deep notches to position first and second legs of the first and second terminals, which are bent downwardly. The alternating shallow and deep notches space the first legs apart from the second legs, respectively. The number of component parts for assembly is therefore reduced. |

1. A method of making a USB 3.0 connector, comprising:
preparing an insulative body including a base that has a base upper wall, a base lower wall, and two base sidewalls interconnecting said base upper and lower walls, a tongue plate projecting forwardly from a front side of said base, a clamp plate projecting forwardly from a bottom side of said base lower wall, and a rear recess that is formed in a rear part of said base and that is surrounded by said base upper and lower walls and said base sidewalls, said base lower wall having a rear end notched in a frontward direction to form a plurality of alternating shallow and deep notches, each of said base sidewalls having a guide groove extending in a front-rear direction, and wherein said insulative body further includes an engaging slot formed in said front side of said base above said clamp plate; preparing first terminals each having a first contact plate for fitting in a bottom side of said tongue plate, and a first leg bending downwardly from said first contact plate for extending through one of said deep notches; fitting the first contact plates of the first terminals in the bottom side of the tongue plate, and extending the first legs respectively through the deep notches; forming second terminals each having a second contact plate for fitting in a top side of said tongue plate, and a second leg bending downwardly from said second contact plate for extending through one of said shallow notches; forming a connection plate which interconnects the second terminals; assembling the second terminals with the tongue plate by pushing forwardly and fitting the second contact plates of the second terminals in the top side of the tongue plate, by extending the second legs of the second terminals through the shallow notches, respectively, and by engaging the second legs of two of the second terminals, which are respectively proximate to the base sidewalls, with the base lower wall in such a manner that each of the two second terminals has the projecting outer edge abutting against an edge of the base lower wall proximate to the respective one of the shallow notches, and has the indented inner edge receiving and engaging an edge of the base lower wall proximate to the respective one of the shallow notches; cutting off the connection plate of the second terminals; preparing an outer shell for covering said insulative body and including a shell top wall, a shell bottom wall, and two shell sidewalls, said shell top wall being longer than and extending beyond a rear end of said shell bottom wall, each of said shell sidewalls having a guide tab for engaging said guide groove of one of said base sidewalls, and said outer shell further includes an engaging lug projecting rearwardly from said shell bottom wall, said shell bottom wall having a bottom side abutting against said clamp plate, said engaging lug being insertable into said engaging slot; and assembling the outer shell with the insulative body by moving forwardly and inserting the insulative body into an interior of the outer shell, wherein the guide tabs are guided into the respective guide grooves by sliding over the respective wedge-shaped protrusions, the engaging lug of the outer shell is inserted into the engaging slot of the base, the clamp plate of the base clamps the bottom side of the shell bottom wall, and the shell bottom wall contacts against the base. |
