Embodiment

For further understanding feature of the present utility model, technological means and the specific purposes that reached, function, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

See also Fig. 1 to Fig. 3, the utility model USB socket connector 100 comprises that an insulating body 10, plurality of terminals 20 and are coated on the shield shell 30 of insulating body 10 peripheries.Described insulating body 10 comprise a base portion 11 that roughly is cuboid, one from base portion 11 front surfaces forward the hyoplastron 12 and of projection from the base portion 11 lower front surface center fixed block 13 of projection forward.

The periphery that described shield shell 30 is positioned at hyoplastron 12 forms a plug receiving space 40, and hyoplastron 12 lower surfaces roughly front end place offer the accepting groove 14 that extends back and run through base portion 11 rear surfaces.Hyoplastron 12 upper surfaces one side place offers one and extends back and run through the signal detection terminal groove 15 of base portion 11 rear surfaces, and signal detection terminal groove 15 rear ends and an accepting groove 14 are electrical connected, and fixed block 13 tops offer a support slot 16.

Described plurality of terminals 20 comprises three conducting terminals 21, an earth terminal 22 and a signal detection terminal 23.Described each conducting terminal 21 and earth terminal 22 have a tabular holding parts 221, and turn forward the elastic arm that extends to form 222, by elastic arm 222 weld part 224 that extended to form by the bending downwards of holding parts 221 rear ends of the contact site 223 that extends to form of bending and upwards forward by holding parts 221 front ends, and bending extends to form described signal detection terminal 23 before the holding parts 221 1 side direction extroversions.

Described shield shell 30 forms hollow structure by sheet metal punching press bending, it comprises roof 31, two side 32 and diapire 33, described roof 31, two side 32 and diapire 33 are equipped with the elastic arm 34 in order to compress USB plug when the USB plug (not shown) stretches into plug receiving space 40, two side 32 rear end lower are provided with the weld part 35 that extends to form downwards, and middle part, diapire 33 rear ends projection backward forms a holding section 36.

Described conducting terminal 21, earth terminal 22 and signal detection terminal 23 are placed in accepting groove 14 and the signal detection terminal groove 15 respectively and bury underground and take shape in the insulating body 10.The holding section 36 of shield shell 30 is fastened in the support slot 16 of insulating body 10, shield shell 30 is sheathed on the insulating body 10, the fixed block 13 of insulating body 10 is butted on the diapire of shield shell 30 with fixed mask housing 30, earth terminal 22 and signal detection terminal 23 conducting in insulating body 10.
