Embodiment

Below in conjunction with drawings and Examples electric connector for socket of the present invention is elaborated:

Consult Fig. 3, the preferred embodiment of electric connector for socket 4 of the present invention comprises a metal shell 41, two pairs of

welding arms

42,43, two perforated portions 44, an insulating body 45 and most signal terminals 46, and definition has the grafting direction (direction shown in Fig. 3 arrow) of pegging graft for a plug connector (figure does not show).

Metal shell 41 has the two relative upstanding side faces 411,412 parallel with the grafting direction, and be located at a bottom surface 413 and the end face 414 on bottom and top of described side 411,412 respectively, push up, bottom surface 414,413 and this two side faces 411,412 define a slot 416 with an interface 415 jointly.In the present embodiment, metal shell 41 outward appearances are cuboid, and bottom surface 413 is designed to the oblique angle with the corner that side 412 is connected, and are the fool proof design of electric connector for socket 4.

Two pairs of

welding arms

42,43 are located at the surface of metal shell 41, be used for fixing metal shell 41 on circuit board (figure does not show), cooperate Fig. 4 and Fig. 5, in present embodiment, metal shell 41 and two pairs of welding arms 42, the 43rd, by a metal plate punching press and a bending forming, form each to welding arm 42 with impact style in metal shell 41, in the time of 43, the corresponding perforated portion that forms is in metal shell 41, in this two side faces 411,412 when forming wherein a pair of welding arm 42 near interface 415 sides, in this two side faces 411,412 corresponding respectively these two perforated portions 44 that form, each perforated portion 44 has a first side portion 441 and the second side portion 442 away from this interface near interface 415, the oblique outstanding metal shell 41 of the rim of the second side portion 442 of each perforated portion 44 forms a slide guide face 443.

One end of each welding arm 42 is connected the top of first and second side portion 441,442 of one of them perforated portion 44, and respectively towards two opposition sides that are positioned at metal shell 41 away from side 411,412 directions bend extension outwardly and down.43 of a pair of in addition welding arms are arranged at the end of metal shell 41 away from interface 415, and this bends outwardly and down respectively from these two side faces 411,412 tops welding arm 43 and extends, and are positioned at two opposition sides of metal shell 41.

Consult Fig. 3 and Fig. 5, insulating body 45 comprises a pedestal 451, a tongue piece 452 and two reference columns 453.Pedestal 451 is embedded at metal shell 41, is positioned at this two perforated portion 44 away from interface 415 sides, and an end is embedded in the metal shell 41, and the other end then exposes to the end of metal shell 41 away from interface 415.Tongue piece 452 is embedded in metal shell 41 from pedestal 451 a end extends towards interface 415 directions, and with top, bottom surface 414,413 separately.453 of two reference columns are positioned at the end that pedestal 451 exposes to metal shell 41, and extend towards bending away from interface 415 directions from pedestal 451 tops two opposition sides, are used for assistant metal housing 41 and are positioned circuit board (figure does not show).

Consult Fig. 3 and Fig. 6, described signal terminal 46 is embedded at the pedestal 451 of insulating body 45 respectively, and an end of each signal terminal 46 extends the surface of tongue piece 452, and is arranged in slot 416, its other end then protrudes in the end of pedestal 451 away from interface 415, and stretches out metal shell 41.In present embodiment, one end of part signal terminal 46 is positioned at the end face of tongue piece 452, as the terminal of USB (USB) B type specification signal transmission usefulness, an end of part signal terminal 46 then is positioned at the bottom surface of tongue piece 452, as the terminal of other standard interface specification signal transmission usefulness.
