Lower grounded metal sheet 270 has the metal shell 101 extended forward for socket connector 100 and contacts Shell fragment 271, described shell fragment 271 is in the horizontal between two power supply terminal Vbus.Described shell fragment 271 is two.Described lower grounded metal sheet 270 includes horizontal body 272 and from horizontal body 272 upwards The installation foot 273 extended, described insulating body 201 is provided with and inserts, for installation foot 273, the installing hole installed. Described lower grounded metal sheet 270 is additionally provided with the lower frame mouth 274 vertically run through, 271, described shell fragment In the front end of lower frame mouth 274, described lower grounded metal sheet 270 is additionally provided with three the overhanging sheets extended back 275.Grounded metal sheet 260 and lower grounded metal sheet 270 front end and socket connector 100 on this utility model The shell fragment 261,271 of contact changes the two panels of contact in the middle of only into, reduces grounded metal sheet short with Vbus The risk on road.Three overhanging sheets 265,275 are connected with plug metal housing 280, it is achieved grounding function.

As shown in Figure 14 to Figure 23, plug metal housing 280 is assembled in the outside of insulating body 201, Top metal-back 281 and substrate shell 282 in the vertical direction coordinate the rear end of plug metal housing 280 Being coated with within it with interior circuit board 250, cable 285 advances through top metal-back 281 and substrate shell 280 Rear end be connected on interior circuit board 250.Insulation shell 290 Overmolded (Over molding) is on top On metal-back 281, substrate shell 282 and cable 285.

Upper shielding plate 286 and lower shielding plate 287 are respectively overlay in upper ledge mouth 264 and lower frame mouth 274.

Compared with prior art, the inner metal sheets 170 on socket connector 100 of the present utility model is at horizontal stroke On direction between two power supply terminal Vbus, will the upper inner metal sheets narrowed width of standard, can To increase upper distance between inner metal sheets 170 and power supply terminal Vbus, reduce the risk of both short circuits. On this utility model pin connector 200, the shell fragment 261 of metal earthing sheet 260 is positioned in a lateral direction Between two power supply terminal Vbus, the shell fragment width of standard will diminish, shell fragment 261 and electricity can be increased Distance between source terminal Vbus, reduces the risk of both short circuits.

This utility model is not limited to above-mentioned specific embodiment, and those of ordinary skill in the art is from upper State design to set out, without performing creative labour, done all conversion, all fall within this utility model Protection domain within.
