  • Power socket device having switches
    Patent number: 8066523
    Abstract: A power socket device having switches is disclosed and has a housing, socket units, positioning members and conductive frames. The housing is formed with recesses communicated with an inner space thereof. The socket unit is installed in the recess, and can be slid forward and backward therein. The socket unit has a socket body and conductive terminals, each of which has a conductive block. The positioning member can be elastically received in the recess and stand upward. The conductive frames are engaged in the housing, and the conductive block can be in contact with or disconnected from the conductive frames. Thus, when the socket unit is slid forward or backward, a close circuit or an open circuit will be formed between the conductive block and the conductive frames, so that it is convenient to switch off the power without additionally adding redundant switches.

  • Electrical connector
    Patent number: 8052467
    Abstract: An electrical connector includes an inner shell, an insulating housing, a plurality of terminals disposed in the insulating housing, an insulating jacket and an outer shell. The inner shell is looped from a metal plate to define an accommodating chamber therein and form a joint at a first top plate thereof. Two portions of the first top plate are punched outward to form two hollow receiving hats. The insulating housing is fastened in the accommodating chamber. The insulating jacket includes a first frame substantially airtightly surrounding the inner shell and a covering piece protruded frontward from a front of a top part of the first frame for covering the joint and locating between the receiving hats. The outer shell surrounds and electrically connects with the inner shell. The outer shell has at least one soldering arm soldered to the printed circuit board for achieving a ground function.
