Detailed description of the invention

Referring to shown in Fig. 1 to Fig. 5, this utility model USB plug 100 includes an insulating body 10, some conducting terminals 20, metal shell 30, internal circuit board 40 and a cable (not shown).

Insulating body 10 includes the hyoplastron 12 that a main part 11 and main body 11 protrude out forward.Being provided with an opening 13 bottom main part 10 and be positioned at two locating dowels 14 of opening 13, opening 13 is rearwardly through main part 10, and opening 13 includes top board 131 and the biside plate 132 downwardly extended from top board 131 left and right sides, and locating dowel 14 is located on top board 131.

Conducting terminal 20 is insert molded in insulating body 10, it includes ground terminal 21, power supply terminal 22 and a pair difference signal terminal 23 between ground terminal 21 and power supply terminal 22, each conducting terminal 21 is provided with the contact site 24 being positioned at front end and the weld part 25 extending back insulating body 10, and contact site 24 is arranged on hyoplastron 12.Ground terminal 21 and power supply terminal 22 are each provided with two weld parts 25 separated between left and right, and difference signal terminal 23 only has a weld part 25, and six weld parts 25 are in line in left-right direction, are positioned at same level.

Relative to prior art, owing to ground terminal 21 and power supply terminal 22 arrange two weld parts 25, USB plug 100 is when transmitting power supply, and electric current can be shunted by two weld parts 25, it is simple to transmits big electric current.

Metal shell 30 houses insulating body 10, and it is provided with a spliced eye 32, and in order to house socket connector (not shown), insulating body 10 hyoplastron 12 is positioned at spliced eye 32, and contact site 24 is exposed to spliced eye 32, in order to dock with socket connector.

Internal circuit board 40 horizontal positioned, is plugged in forward in insulating body 10 opening 13, by side plate 132 clamping position, abuts up simultaneously and be affixed on top board 131.Internal circuit board 40 has the hole, location 44 inserted for locating dowel 14, upper surface be provided with weld together one by one with weld part 25 some before weld sheet 45 and weld together with cable some weld sheet 46, making conducting terminal 20 and cable realize electrically conducting, cable extends back metal shell 30.

Although being example purpose, have been disclosed for preferred implementation of the present utility model, but those of ordinary skill in the art is it will be appreciated that in the case of without departing from by scope and spirit of the present utility model disclosed in appending claims, various improvement, to increase and replace be possible.
