  • Patent number: 9306337
    Abstract: An electrical connector includes an insulative housing, a number of contacts retained in the insulative housing, a metallic outer shell enclosing the insulative housing, and a metallic inner shell positioned between the metallic outer shell and the insulative housing. The insulative housing includes a base and a tongue portion protruding from the base. The contacts include a number of flat contacting portions exposed on a top surface and a bottom surface of the tongue portion, respectively. The metallic inner shell includes at least two pieces which are separately made and fixed to the insulative housing.

  • Patent number: 7399188
    Abstract: A receptacle connector includes a housing, an insulating body and a plurality of terminals. The housing defines a recess for receiving the insulating body. The insulating body defines cavities on top and bottom surfaces thereof. A back surface of the insulating body defines terminal channels communicating with the corresponding cavities. Each of the terminals has a base portion. The middle of the base portion extends forward to form an annular soldering portion and a connecting portion extends rearward from the base portion. A free end of the connecting portion bends to form a contact portion. The base portion and the connecting portion are received in the cavities and the contact portion is received in the terminal channel. The soldering portion protrudes out from a front surface of the insulating body for being soldered in a printed circuit board.

  • Patent number: 7285016
    Abstract: A connector assembly includes a dielectric housing and a plurality of conductive terminals. The dielectric housing defines a plurality of terminal slots and terminal pores, which together contain said conductive terminals. Said terminal pores are defined on both sides of the dielectric housing. Each of the conductive terminals contains a vertical leg, and the vertical leg bends sideward and forms a bending portion, the bending portion extends upward bends to form a grasping portion. The grasping portion expands an arm and forms a contact portion at its end. The bending portions bending left and those bending right together forms a space between their vertical legs, which divides the vertical legs into two groups. The vertical legs are contained into said terminal pores and extrude beyond the bottom surface of the dielectric housing. Thus, an interspace for extra cables threading through is formed between the two groups of vertical legs.
