Embodiment

Consult Fig. 1 and Fig. 2, first embodiment of the utility model provides a kind of electric connector socket, and it comprises an insulating body 100, a plurality of signal terminal set 200 and a plurality of ground terminal set 300.

Insulating body 100 comprises a base 110 and a tongue piece 120.Base 110 comprises at least one holes 111; This holes 111 is opened in the surface of base 110; Preferably holes 111 is offered for running through base 110 in the present embodiment, but the utility model do not limit and run through, and all offers holes 111 between adjacent signal terminal set 200 and the ground terminal set 300.Tongue piece 120 is for extending the flat board from base 110, and it comprises a faying surface 121, and this faying surface 121 is in order to overlap corresponding electrical connector plug.

Consult Fig. 3 and Fig. 4, a plurality of signal terminal set 200 are embedded in the insulating body 100, and each signal terminal set 200 extends to base 110 and passes base 110 from tongue piece 120.In the present embodiment, preferably each signal terminal set 200 comprises two signal terminals 210/220 (positive pole and negative pole), and each signal terminal 220 (210) comprises a signal contact jaw 221, a signal welding ends 222 and a signal stage casing 223.Signal contact jaw 221 is embedded in the faying surface 121 that in the tongue piece 120 and partly exposes to tongue piece 120, in order to electrically connect corresponding electrical connector plug.Signal welding ends 222 passes base 110, in order to be welded in a circuit board.223 in signal stage casing is embedded in the base 110 and between signal contact jaw 221 and signal welding ends 222.

A plurality of ground terminal set 300 are worn fork with aforesaid a plurality of signal terminal set 200 and are embedded in side by side in the insulating body 100, and ground terminal set 300 extends to base 110 and passes base 110 from tongue piece 120.In the present embodiment; Preferably each ground terminal set 300 comprises two earth terminals 310/320; Each earth terminal 310 (320) comprises a ground connection contact jaw 311, a ground connection welding ends 312 and a ground connection stage casing 313; Ground connection contact jaw 311 is embedded in the faying surface 121 that in the tongue piece 120 and partly exposes to tongue piece 120, and in order to electrically connect corresponding electrical connector plug, preferably ground connection contact jaw 311 exposes to faying surface 121 side by side with signal contact jaw 221.Ground connection welding ends 312 passes base 110, in order to be welded in aforesaid circuit board.313 in ground connection stage casing is embedded in the base 110 and between ground connection contact jaw 311 and ground connection welding ends 312.Holes 111 is through running through base 100 between adjacent signal terminal set 200 and the ground terminal set 300; Preferably holes 111 be opened in a signal stage casing 223 and the ground connection stage casing 313 that is adjacent between; All offer a holes 111 between signal stage casing 223 that each is adjacent and the ground connection stage casing 313, and the degree of depth of holes 111 foot exposes in the same holes 111 signal stage casing 223 and adjacent ground connection stage casing 313 parts.
