Refer to shown in Fig. 1 to Fig. 4, the application's positive anti-plug USB socket comprises interfacing part 10, be sheathed on the metal shell 20 outside described interfacing part 10 and be shaped in the insulation afterbody 30 of described interfacing part 10 and described metal shell 20 rear end.Plate 13, the insulating body 15 that described first end subgroup 11, second terminal group 12 and plate 13 in described isolation are taken shape in one and the earthing member 14 be sheathed on described insulating body 15 in the isolation that described interfacing part 10 comprises first end subgroup 11, second terminal group 12, be held between described first end subgroup 11 and described second terminal group 12.
Described first end subgroup 11, second terminal group 12 comprises some conducting terminals respectively and described some conducting terminals is taken shape in the collets of one.In described isolation, plate 13 is taken shape in one with described second terminal group 12 by described collets.Plate 13 in described first end subgroup 11, second terminal group 12 and interior isolation thereof is taken shape in one by described insulating body 15.
The docking tongue 101 that described interfacing part 10 comprises base portion 103, extend to form from base portion forward direction and in described base portion 103 and the stage portion 102 of docking between tongue 101.Described stage portion 102 external diameter is greater than described docking tongue 101 and is less than described base portion 103.Described earthing member 14 is sheathed in described stage portion 102.The both sides end face of described base portion 103 is provided with fixture block 151.
Refer to shown in Fig. 5 to Fig. 7, Fig. 9, Figure 10, the leg 135 that in described isolation, plate 13 comprises main part 131, is formed at the docking draw-in groove 132 of front end, described main part 131 both sides, is positioned at the protuberance 136 in described docking draw-in groove 132 front, is positioned at the spot-welding part 134 at described docking draw-in groove 132 rear and extends from rear end, described main part 131 both sides.Described spot-welding part 134 is positioned at stage portion 102 position of described interfacing part 10, and described spot-welding part 134 is exposed to described insulating body 15 outer surface in both lateral sides.
Described earthing member 14 in the form of a ring structure is sheathed on described stage portion 102 place, described earthing member 14 comprises circular body portion 141, from the upper and lower both sides, rear end of described circular body portion 141 respectively to the upper extension extension 144, the catch 145 that extends to form respectively to upper bending from upper and lower both sides, described circular body portion 141 rear end that are formed of bending again, described catch 145 is positioned at described extension 144 both sides.Hole clipping 143 on the fixture block 151 being snapped in described base portion 103 in addition integrally extended to form with described extension 144.
In described isolation, the spot-welding part 134 of plate 13 contacts with the both sides 142 of the circular body portion 141 of described earthing member 14 extend the two sides of described insulating body 15 at stage portion 102 place after, by the technique of spot welding, described spot-welding part 134 is welded in one with the both sides 142 of earthing member 14.The end face up and down that the Extendible flake 144 of described earthing member 14 is positioned at described base portion 103 contacts with described metal shell 20, by the technique of spot welding, described Extendible flake 144 is welded on described metal shell 20.So, when described butt connector (not shown) insertion is docked with interfacing part 10, the insertion force that in the isolation of described interfacing part 10, the protuberance 136 of front end, plate 13 both sides bears will pass to described earthing member 14 by described spot-welding part 134, strength is then finally passed to metal shell 20 by described Extendible flake 144 by described earthing member 14, docking strength is digested and assimilated by socket entirety, and not merely relies on plate 13 in isolation to digest.Meanwhile, spot welding connected mode, make the ground connection contact performance of earthing member better, more enhance the globality of USB socket, intensity is higher.
Described earthing member 14 is positioned at the catch 145 of described Extendible flake 144 both sides for keeping out described butt connector, prevents butt connector from excessively inserting and injuring interfacing part 10.The strength that described butt connector abuts described catch 145 also can be connected with the spot welding of metal shell 20 by described Extendible flake 144 and pass to metal shell 20, prevents butt connector insertion force from acting on described interfacing part 10 and causing the dislocation between interfacing part 10 and metal shell 20.
Refer to shown in Fig. 8, in described isolation, the middle vacancy of the main part 131 of plate 13 forms breach 133, and described first end subgroup 11, second terminal group 12 comprises earth terminal 121, power supply terminal 122, some signals and control terminal 123, power supply terminal 124, earth terminal 125 successively respectively.Described power supply terminal 122, some signals and control terminal 123, power supply terminal 124 are arranged in breach 133 position of described isolation plate 13, and described earth terminal 121,125 is arranged in main part 131 position of described isolation plate 13.Because of some particular/special requirement, described power supply terminal 122, the terminal thickness of 124 is greater than described earth terminal 121, the thickness of 125, by described power supply terminal 122, the 124 gap position places being placed in described isolation plate 13 can prevent the power supply terminal 122,124 of described thickening and plate 13 in described isolation from the problem of short circuit occurring.
The spot-welding part 134 that the application's positive anti-plug USB socket is arranged in the isolation plate 13 at stage portion 102 place of described interfacing part 10 is exposed to the both sides of described insulating body 15 and contacts with the both sides 142 of the earthing member 14 being sheathed on described stage portion 102 place, by the mode of spot welding, plate 13 and described earthing member 14 fixing in described isolation are integrated again, the grafting strength of butt connector is born by USB socket entirety, strengthens the steadiness of product.
