Patent ID: 8801467

Claim:
An electrical connector adapted for being vertically mounted on a circuit board placed horizontally, comprising: an insulating housing having an erect base body and an erect tongue board extending forward from a front of the base body; a plurality of conductive terminals each having a fastening arm vertically disposed in the base body of the insulating housing, a top distal end of the fastening arm extending forward and being inclined sideward to form a contact arm of which a free end is slantwise bent back, and a bottom distal end of the fastening arm extending rearward and being inclined downward to form a touching arm of which a free end is slantwise bent back, the contact arms elastically projecting sideward out of a side face of the tongue board and being arranged at regular intervals along a vertical direction, the touching arms projecting rearward out from a bottom of the base body and being horizontally arranged at regular intervals along a transverse direction; a front shell looped from a metal plate to show a rectangular tubular shape, the front shell being mounted rearward to the insulating housing with the tongue board together with the contact arms of the conductive terminals being apart located therein; and a rear shell curved from a metal plate, the rear shell being covered to the base body of the insulating housing and over the touching arms of the conductive terminals, wherein the electrical connector is mounted onto the circuit board with the touching arms of the conductive terminals being elastically against and further pressed upward by the circuit board to form electrical connection with the circuit board, wherein a back of the base body is concaved forward to form a receiving chamber, the fastening arm of the conductive terminal is substantially of an inverted-L shape, the fastening arms apart arranged in the receiving chamber of the base body at regular intervals with the overall length thereof lengthening by degrees from the bottom up, the rear shell seals up the receiving chamber, and wherein a plurality of restraining portions is protruded in a bottom of the receiving chamber of the base body and arranged at regular intervals along, the transverse direction, a holding arm is longitudinally connected between the bottom distal end of the fastening arm and the touching arm with a fixing ear protruding sideward at one edge thereof, a bottom of each fastening arm is clamped between adjacent two restraining portions, the fixing ear abuts against a bottom of the corresponding restraining portion to prevent the conductive terminal from moving upward when the circuit board presses the touching arm upward.
