  • Patent number: 7931501
    Abstract: An electrical connector includes an insulating housing, a plurality of terminals and a shielding shell. The insulating housing has a base body and a tongue. Two sides of the front surface of the base body define two inserting slots. A propping portion is perpendicularly connected between two face-to-face insides of the inserting slot. The terminals are disposed in the insulating housing respectively. The shielding shell is mounted to the insulating housing, and has a tongue sheath with two side plates. A rear edge of each side plate extends rearward to form a fastening piece with a clipping opening.

  • Patent number: 7837506
    Abstract: An electrical connector includes an inner shell which defines a receiving recess and has a base board, an insulating body which defines a receiving chamber with a front end being opened freely for receiving the inner shell therein, a plurality of terminals insert-molded in the insulating body and exposed to the receiving recess, and an outer shell which encloses the insulating body and has a base plate. A connecting slot is opened in and penetrates through a rear wall of the receiving chamber. A rear edge of the base board is provided with a contact slice passing through the connecting slot and then bent against the rear wall. A rear edge of the base plate is bent downward and then arched forward to form a contact tail which is located behind the rear wall and electrically abuts against the contact slice to achieve a ground function of the inner shell.

  • Publication number: 20100068903
    Abstract: An electrical connector includes a housing, a plurality of terminals fixed in the housing and a shell encircling the housing. The shell has two opposing sidewalls each having a holding portion extending and bending outward therefrom and being spaced a distance from a bottom of the shell. An inserting portion extends downward from a place of the holding portion. The electrical connector is adapted for being mounted to a printed circuit board which defines a receiving space and two fixing holes with the inserting portions inserted into the fixing holes and the holding portions placed on the printed circuit board. Therefore, the electrical connector has a portion below the holding portions sunk in the receiving space and the total height thereof is reduced.
