[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

Please refer to Fig. 1 to shown in Figure 8, the utility model electric connector comprises a lengthwise type insulating body 10 and two liftout attachments 20 in order to circuit board 3 is connected on the motherboard (not shown).

Insulating body 10 comprises pair of sidewalls 11,11 of sidewalls are provided with central slot 12 along long axis direction, central authorities slot 12 both sides are provided with two row and form the terminal accommodation holes 13 that is communicated with central slot, conducting terminal 14 is contained in the described terminal accommodation holes 13, a pair of turriform portion 15 is extended vertically upward by these insulating body 10 two ends integratedly, and form a pair of receiving space 16 to accommodate liftout attachment 20, this receiving space 16 is connected with above-mentioned central slot 12, turriform portion 15 is provided with a pair of sidewalls 156 and an end wall 157, surround above-mentioned receiving space 16 jointly by a pair of sidewalls 156 and an end wall 157, be provided with an accepting hole 1571 in the end wall 157, electric connector is provided with the metallic tines 18 in order to locate mutually with motherboard in addition, this metallic tines 18 is contained in the accepting hole 1571, on insulating body side wall ends (being turriform portion 15) inboard, be provided with stop section 151, the stop section is provided with downwards and outward-dipping inclined-plane 152, turriform portion 15 inboard positions near end wall 157 are provided with and articulate axis hole 153, and turriform portion upper outside is provided with draw-in groove 154.
