Detailed description1,745 words

#With reference to FIG. 1, FIG. 3 and FIG. 6, an electrical connector in accordance with an embodiment of the present invention is adapted for being vertically mounted on a circuit board 70 placed horizontally. The electrical connector includes an insulating housing 10, a plurality of conductive terminals 20, a front shell 30 looped from a metal plate to show a rectangular tubular shape, and a rear shell 40 curved from a metal plate.

#Referring to FIG. 1, FIG. 3 and FIG. 6, the insulating housing 10 has an erect base body 11 and an erect tongue board 12 extending forward from a front of the base body 11. Each of the conductive terminals 20 has a fastening arm 21 vertically disposed in the base body 11 of the insulating housing 10. A top distal end of the fastening arm 21 extends forward and is inclined sideward to form a contact arm 24 of which a free end is slantwise bent back. A bottom distal end of the fastening arm 21 extends rearward and is inclined downward to form a touching arm 25 of which a free end is slantwise bent back. The contact arms 24 elastically project sideward out of a side face of the tongue board 12 and are arranged at regular intervals along a vertical direction. The touching arms 25 project rearward out from a bottom of the base body 11 and are horizontally arranged at regular intervals along a transverse direction. The front shell 30 is mounted rearward to the insulating housing 10 with the tongue board 12 together with the contact arms 24 of the conductive terminals 20 being apart located therein. The rear shell 40 is covered to the base body 11 of the insulating housing 10 and over the touching arms 25 of the conductive terminals 20. The electrical connector is mounted onto the circuit board 70 with the touching arms 25 of the conductive terminals 20 being elastically against and further pressed upward by the circuit board 70 to form electrical connection with the circuit board 70.

#Referring to FIG. 3, FIG. 4, FIG. 5 and FIG. 6, a back of the base body 11 is concaved forward to form a receiving chamber 17. The fastening arm 21 of the conductive terminal 20 is substantially of an inverted-L shape. The fastening arms 21 are apart arranged in the receiving chamber 17 of the base body 11 at regular intervals with the overall length thereof lengthening by degrees from the bottom up. The rear shell 40 seals up the receiving chamber 17. The side face of the tongue board 12 of the insulating housing 10 defines a plurality of terminal grooves 13 arranged at regular intervals along the vertical direction and each longitudinally extending through the base body 11 to communicate with the receiving chamber 17. A connecting arm 22 is longitudinally connected between the top distal end of the fastening arm 21 and the contact arm 24 with a pair of fixing barbs 221 oppositely protruding at two edges thereof. The contact arm 24 passes forward through the base body 11. The fixing barbs 221 are snapped in two opposite inner sidewalls of a rear of the corresponding terminal groove 13 to secure the connecting arm 22 in the rear of the terminal groove 13 so as to ensure the contact arm 24 is steadily pressed into the terminal groove 13. A plurality of restraining portions 14 is protruded in a bottom of the receiving chamber 17 of the base body 11 and arranged at regular intervals along the transverse direction. A holding arm 23 is longitudinally connected between the bottom distal end of the fastening arm 21 and the touching arm 25 with a fixing ear 231 protruding sideward at one edge thereof. A bottom of each fastening arm 21 is clamped between adjacent two restraining portions 14. The fixing ear 231 abuts against a bottom of the corresponding restraining portion 14 to prevent the conductive terminal 20 from moving upward when the circuit board 70 presses the touching arm 25 upward.
